throughout their life-cycle, to protect associated personnel and property, unrelated personnel and
property, and the environment from the potential damaging effects of an accident involving
ammunition and explosives.

This Standard applies to the Office of the Secretary of Defense, the Military
Departments, the Office of the Chairman of the Joint Chiefs of Staff, the Combatant Commands,
the Office of the Inspector General of the Department of Defense, the Defense Agencies, the
DoD Field Activities, and all other organizational entities in the Department of Defense
(hereafter referred to collectively as the “DoD Components”).

This Standard is effective immediately and is mandatory for use by all DoD Components.
The Heads of the DoD Components may issue supplementary guidance only when necessary to
provide for unique requirements within their respective Components. A copy of such
supplementary guidance shall be forwarded to the Chairman, Department of Defense Explosives
Safety Board (DDESB).

Forward recommendations for change to this Standard through channels to:

C1. CHAPTER 1
INTRODUCTION

C1.1. GENERAL

C1.1.1. These explosive safety standards (hereafter referred to as “Standards”) are issued
under the authority of DoD Directive 6055.9E (Reference (a)). These Standards are designed to
manage risks associated with DoD-titled ammunition and explosives (AE) by providing
protection criteria to minimize serious injury, loss of life, and damage to property. It is DoD
policy to comply with the applicable Federal and State laws and regulations. Where the Standard
conflicts with such laws and regulations, DoD components shall ensure the safety of DoD
personnel and the public while complying and notify the Chairman, DDESB, through its Board
Member, of the conflict. These Standards are not intended to be so rigid as to prevent the DoD
Components from accomplishing their assigned missions.

C1.1.2. Criteria provided by these Standards are given in English units (e.g., ft, lb, psi.) with
metric equivalents shown in brackets (e.g., [m, kg, kilopascal (kPa)]).

C1.2. EXPLOSIVES SAFETY MANAGEMENT (ESM) POLICY

As established in DoD Directive 6055.9E (Reference (a)) and consistent with peacetime,
contingency, or wartime operational requirements and corresponding DoD military munitions
requirements from the broadest and most fundamental Explosives Safety Management (ESM)
perspective, it is DoD policy to:

C1.2.1. Provide the maximum possible protection to people and property from the potential
damaging effects of DoD military munitions (explosive and chemical). Applying the Standards
herein provides only the minimum protection criteria for personnel and property, and greater
protection should always be provided when practicable.

C1.2.2. Minimize exposures consistent with safe and efficient operations (i.e., expose the
minimum number of people for the minimum time to the minimum amount of explosives or
chemical agents).

C1.3. APPLICABILITY

These Standards:

C1.3.1. Apply to DoD-titled AE wherever it is located.

C1.3.2. Apply to DoD personnel and property when potentially endangered by known
host-nation or off-installation AE hazards.

19 CHAPTER 1
DoD 6055.09-STD, February 29, 2008

C1.3.3. Govern DoD facilities siting and construction, except as indicated in paragraph
C1.3.5.

C1.3.4. Apply to the evaluation of non-DoD explosives siting submissions on DoD installations
(see paragraph C9.8.22.).

C1.3.5. Do not apply for the exceptions described in subparagraphs C1.3.5.1. through
C1.3.5.3. These exceptions must be documented per subparagraph C1.3.5.4.

C1.3.5.1. Existing facilities, or those approved for construction under then-current

editions of these Standards. This exception applies for the balance of the useful lives of such
facilities provided:

C1.3.5.1.1. The facility continues to be used for its intended purpose.

C1.3.5.1.2. The explosives safety hazards are not increased.

C1.3.5.1.3. Redesign or modification is not practicable.

C1.3.5.1.4. The quantity of AE cannot be reduced for reasons of operational

necessity.

C1.3.5.2. Those planned facilities that do not meet these Standards, but have been
certified by the Head of the DoD Component (see paragraph C1.5.4.) as essential for operational
or other compelling reasons.

C1.3.5.3. To other situations that, upon analysis by both the DoD Component and the
Department of Defense Explosives Safety Board (DDESB), are determined to provide the
required degree of safety through use of protective construction or other specialized safety
features.

C1.3.5.4. The DoD Components must document the above exceptions in permanent
records. These records must include:

C1.3.5.4.1. The effective date the applicable Standards were first published.

C1.3.5.4.2. The date the deviant facility was either approved, from an explosives
safety viewpoint, for use or was first used in the deviating manner.

C1.4. TERMINATION OF USE OF FACILITIES STORING AE

Each storage facility no longer used to store ammunition and explosives must undergo a process
to ensure that AE and any visible explosives residues are removed within 180 days from the last
use of the storage facility. Those procedures help ensure that no threats to human health or the
environment remain when the unit is no longer to be used to store AE. (Ammunition storage

20 CHAPTER 1
DoD 6055.09-STD, February 29, 2008

units (ASU) that have been used to store waste military munitions must also comply with the
closure procedures in Chapter 14, section C14.6.) Those procedures shall include the following:
C1.4.1. Emptying the storage facility of all AE and related materials.

C1.4.2. Cleaning the storage facility, as required, to remove any visible explosives residue.

C1.4.3. Visually inspecting the storage facility for the presence of remaining ammunition or
explosives or visible explosives residue by a knowledgeable individual appointed by the
installation or responsible activity commander.

C1.4.4. Removing from the storage facility all fire and chemical hazard symbols and
marking the storage facility as empty.

C1.4.5. Securing the storage facility to prevent inadvertent use or access.

C1.4.6. Notifying the applicable emergency response and regulatory authorities of the
change in the storage facility’s use.

C1.4.7. Recording the date the storage facility was inspected, the name and position of the
inspector, and the results in permanent real estate records.

C1.5. WAIVERS, EXEMPTIONS, AND SECRETARIAL EXEMPTIONS OR

CERTIFICATIONS

C1.5.1. General. When strategic or compelling operational requirements necessitate

deviation from these Standards, the DoD Component shall:

C1.5.1.1. Acknowledge and accept the added risk to personnel or property.

C1.5.1.2. Document both the risk and methods used to reduce it to an acceptable level in
relation to the operational requirements.

C1.5.2. Waivers. A waiver is a written authority that permits temporary deviation from
these Standards for strategic or compelling operational requirements. Generally, it is granted for
a period not to exceed 5 years pending termination of the waiver or correction of the waived
conditions. Exceptional situations may require a waiver to be reissued to allow either
completion of the operation requiring the waiver or time for completion of the corrective action.
In such cases, the next higher approval authority shall reissue the waiver; the exception is when
the head of the DoD Component or the responsible Combatant Commander has issued the
waiver. Waivers shall be reviewed for applicability and currency at intervals not to exceed 2
years. Waivers may be granted by the official with both:

C1.5.2.1. The assigned responsibilities consistent with the level of risk.

21 CHAPTER 1
DoD 6055.09-STD, February 29, 2008

C1.5.2.2. The authority to control the resources required to accomplish the corrective
action.

C1.5.3. Exemptions. An exemption is a written authority that permits long-term

noncompliance with these Standards for strategic or compelling operational requirements.
Exemptions shall be reviewed for applicability and currency at intervals not to exceed 5 years.
Exemptions may be granted by law, Congressional action, and the official assigned
responsibilities consistent with the level of risk.

C1.5.4. Secretarial Exemptions or Certifications. A Secretarial Exemption or Certification is

a written authority granted by a Secretary of a Military Department to deviate from the
requirements of these Standards to allow the construction of new potential explosion sites (PES)
or exposed sites (ES). To validate the strategic or compelling operational requirements and
ensure the identification of risks and exposures, these exemptions or certifications shall be
reviewed at intervals not to exceed 5 years.

C1.5.5. Report Control Symbol (RCS) DD-AT&L(AR)1643. (See DoD 8910.1-M

(Reference (b)).) When the DDESB requests information on exemptions and waivers, the DoD
Components shall provide the following, as applicable:

C1.5.5.1. Identification number (DoD Component-derived).

C1.5.5.2. Classification (waiver or exemption); approval authority’s title; and date of

approval, expiration, or cancellation, as applicable.

C1.5.5.3. Location.

C1.5.5.4. Condition waived or exempted.

C1.5.5.5. Net Explosive Weight (NEW) or Net Explosive Weight for Quantity-Distance
(NEWQD) by Hazard Division (HD) at a PES.

C1.5.5.6. Distance from the PES to any ES and a brief description of the ES to include:
type, estimated value of any property involved, and location of the property (e.g., on or off
installation).

C1.5 5.7. Estimated number of DoD and non-DoD personnel located at the ES.

C1.5.5.8. Calculated hazard distances (see public exclusion distance), as applicable.

C2. CHAPTER 2
REACTION EFFECTS

C2.1. INTRODUCTION

This chapter describes the expected effects of AE reactions.

C2.2. HD 1.1 EFFECTS

C2.2.1. Blast

C2.2.1.1. Blast Wave Phenomena. In an incident involving HD 1.1 or HD 1.1 with any
other HD (a HD 1.1 event), the violent release of energy creates a sudden and intense pressure
disturbance termed the “blast wave.” The blast wave is characterized by an almost instantaneous
rise from ambient pressure to a peak incident pressure (Pi). This pressure increase, or “shock
front,” travels radially outward from the detonation point, with a diminishing velocity that is
always in excess of the speed of sound in that medium. Gas molecules making up the front
move at lower velocities. This velocity, which is called the “particle velocity,” is associated with
the “dynamic pressure,” or the pressure formed by the winds produced by the shock front.

C2.2.1.1.1. As the shock front expands into increasingly larger volumes of the
medium, the incident pressure decreases and, generally, the duration of the pressure-pulse
increases.

C2.2.1.1.2. If the shock wave impinges a rigid surface (e.g., a building) at an angle to
the direction of the wave’s propagation, a reflected pressure is instantly developed on the surface
and this pressure rises to a value that exceeds the incident pressure. This reflected pressure is a
function of the incident wave’s pressure and the angle formed between the rigid surface and the
plane of the shock front.

C2.2.1.2. Partially Confined Explosions. When an explosion occurs within a structure,

the peak pressure associated with the initial shock front will be both high and amplified by
reflections within the structure. In addition, the accumulation of gases from the explosion will
exert additional pressure and increase the load duration within the structure. This effect may
damage or destroy the structure unless the structure is designed to either withstand or vent the
gas and shock pressures. Structures that have one or more strengthened walls may be vented for
relief of excessive gas by either using frangible construction for the remaining walls or roof or
through the use of openings. This type of construction will allow the gas from an internal
explosion to spill out of the structure. Once released from confinement, these pressures, referred
to as “exterior” or “leakage” pressures, expand radially and may affect external structures or
personnel.

C2.2.1.3. Quantity-Distance (QD) – K-factors. Throughout this Standard, NEW is used

to calculate Quantity-Distance (QD) by means of a formula of the type D (ft) = K•W1/3, where

23 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

“D” is the distance in feet, “K” is a factor (also called K-factor) that is dependent upon the risk
assumed or permitted, and “W” is the NEW in pounds. When metric units are used, the symbol
“Q” denotes Net Explosive Quantity (NEQ) in kilograms. In the formula D (m) = Km•Q1/3, the
distance “D” is expressed in meters. Thus, the units of the K-factor ("K" in the English system)
are ft/lb1/3 and ("Km" in the metric system) m/kg1/3. The value of “K” in English units is
approximately 2.52 times “Km.” For example, if D (m) = 6•Q1/3, then D (ft) = 15.12•W1/3.
Distance requirements determined by the formula with English units are sometimes expressed by
the value of “K,” using the terminology K9, K11, K18, to mean K = 9, K = 11, and K = 18.

C2.2.1.4. Expected Blast Pressures at QD. Table C2.T1. presents the incident pressures
that would be expected at various K-factors from HD 1.1 events.

C2.2.1.5. General Blast Effects On Structures

C2.2.1.5.1. Conventional Structures. Conventional structures are generally designed

to withstand roof-snow loads of 0-50 pounds per square foot [0-2.4 kPa] or wind loads up to 90
miles per hour [145 kilometers per hour] or both. At 90 mph [145 kph], the wind load equates to

24 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

0.14 psi [1.0 kPa]. Given the pressures shown in Table C2.T1. for the selected K-factors, it is
evident that, even at IBD, conventional structures may not provide complete protection from the
blast. Generally, the weakest portions of any conventional structure are the windows. Table
C2.T2. provides the probability of breaking typical windows at various K-factors and associated
incident pressures from HD 1.1 events.

25 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.1.5.2. Above Ground Structures (AGS). These are generally considered

conventional structures and provide little protection from blast or fragmentation. (See paragraph
C2.2.5.).

C2.2.1.5.3. Earth-Covered Magazines (ECM). High reflected pressure and impulse

produced by an explosion at an adjacent ECM can damage doors and headwalls and propel
debris into an ECM so that explosion is communicated by impact of such debris upon the
contents. When separated from each other by the minimum distances required by Table C9.T6.,
ECM (see paragraph C5.2.1.) provide virtually complete protection of AE against the
propagation effects of an explosion. However, AE in adjacent ECM may be damaged and
structural damage ranging from cracks in concrete, damage to ventilators and doors, to complete
structural failure, may occur. (When ECM containing HD 1.1 AE are sited so that any one is in
the forward sector of another, the two must be separated by distances greater than the minimum
permitted for side-to-side orientations. The greater distances are required primarily for the
protection of door and headwall structures against blast from a PES forward of the exposed
magazine, and to a lesser extent due to the directionality of effects from the source.)

C2.2.1.5.4. Underground Storage Facilities. Underground facilities sited per section

C9.7. provide a high degree of protection against propagation of an explosion between chambers,
and between underground and aboveground structures. An HD 1.1 explosion in an underground
storage facility causes very high pressures of prolonged duration. Blast waves and the
accompanying gas flows will travel throughout the underground facility at high velocity.

C2.2.1.5.5. Barricaded Open-Storage Modules. Barricaded open-storage modules

(see paragraph C5.2.2.) provide a high degree of protection against propagation of explosion.
However, if flammable materials are present in nearby cells, subsequent propagation of
explosion by fire is possible. When an explosion occurs, AE in adjacent modules separated by
K1.1 [Km 0.44] will be thrown tens of meters, covered with earth, and unavailable for use until
extensive uncovering operations, and possibly maintenance, are completed. Items at K2.52
[Km 1.0] separation distance from a donor explosion are expected to be readily accessible.

C2.2.1.5.6. High Performance Magazine (HPM). When separated from other AE

storage magazines by the minimum distances required by Table C9.T6., the HPM provides
virtually complete protection of AE against the propagation effects of an explosion. The HPM’s
2-story transfer and storage areas are enclosed by a pre-engineered metal building, which may be
severely damaged as a result of an explosion at a nearby PES. The amount of damage to be
expected at various pressure levels is described in paragraph C2.2.5. Access to the AE in a HPM
may require extensive cleanup and the use of a mobile crane, unless special design
considerations are incorporated into the metal building design. The HPM contains multiple
storage cells, which are designed to limit the maximum credible event, as discussed in
subparagraph C9.3.1.1.3. In the event of an internal explosion involving the maximum credible
event (MCE), the pre-engineered metal building can be expected to be completely destroyed, and
AE not involved in the explosion can be expected to be significantly damaged and no longer
usable.

C2.2.1.6. General Blast Effects on Personnel. Tables C2.T3. through C2.T5. describe
the expected effects of blasts on personnel.

C2.2.1.7. Computation of Blast Effects. Many of the blast effects described in this
section were computed with the DDESB Blast Effects Computer (Reference (c)), which can be
used to estimate similar effects associated with various NEW, facilities, and distances.

* Lethality due to lung rupture is caused by a combination of pressure
and impulse. This combination will vary with the charge weight.
(NOTE: In this example, the probability of lethality is assumed to be 99.9%.)

C2.2.2. Fragments

C2.2.2.1. General. An important consideration in the analysis of the hazards associated

with an explosion is the effect of any fragments produced. Although most common in HD 1.1 or
HD 1.2 events, fragmentation may occur in any incident involving AE. Depending on their
origin, fragments are referred to as “primary” or “secondary” fragments.

C2.2.2.1.1. Primary fragments result from the shattering of a container (e.g., shell
casings, kettles, hoppers, and other containers used in the manufacture of explosives and rocket
engine housings) in direct contact with the explosive. These fragments usually are small,
initially travel at thousands of feet per second, and may be lethal at long distances from an
explosion.

C2.2.2.1.2. Secondary fragments are debris from structures and other items in close
proximity to the explosion. These fragments, which are somewhat larger in size than primary
fragments and initially travel at hundreds of feet per second, do not normally travel as far as
primary fragments.

C2.2.2.1.3. The earth cover of an underground facility may rupture and create a
significant debris hazard.

C2.2.2.1.4. A hazardous fragment is one having an impact energy of 58 ft-lb

[79 joules] or greater.

C2.2.2.1.5. The Hazardous Fragment Distance is the distance at which the areal
density of hazardous fragments or debris becomes one per 600 ft2 [55.7 m2].

C2.2.3. Thermal Hazards

C2.2.3.1. General. Generally, thermal hazards from a HD 1.1 event are of less concern
than blast and fragment hazards.

28 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.3.2. Personnel. It normally takes longer to incur injury from thermal effects than
from either blast or fragmentation effects because both blast and fragmentation occur almost
instantaneously. The time available to react to a thermal event increases survivability.

C2.2.3.3. Structures, Material, and AE. The primary thermal effect on structures,
material, and AE is their partial or total destruction by fire. The primary concern with a fire
involving AE is that it may transition to a more severe reaction, such as a detonation.

C2.2.4. Groundshock and Cratering

C2.2.4.1. General

C2.2.4.1.1. In an airburst, there may be a downward propagation of groundshock and

cratering may be reduced or eliminated.

C2.2.4.1.2. In a surface burst, groundshock is generated and cratering can be

significant.

C2.2.4.1.3. A buried or partially buried detonation produces the strongest

groundshock; however, if the explosion is deep enough, no crater will be formed.

C2.2.4.2. Underground Facilities. AE protection can be achieved by proper chamber

spacing. An HD 1.1 explosion will produce ground shocks that may rupture the earth cover and
eject debris. (See section C9.7.)

C2.2.5. Expected Consequences

C2.2.5.1. Barricaded Aboveground Magazine (AGM) Distance - 6W1/3 ft [2.38Q1/3 m] -

27 psi [186.1 kPa]. At this distance:

C2.2.5.1.1. Unstrengthened buildings will be destroyed.

C2.2.5.1.2. Personnel will be killed by blast, by being struck by debris, or by impact

against hard surfaces.

C2.2.5.1.3. Transport vehicles will be overturned and crushed by the blast.

C2.2.5.1.4. Explosives-loaded vessels will be damaged severely, with propagation of

explosion likely.

C2.2.5.1.5. Aircraft will be destroyed by blast, thermal, and debris effects.

C2.2.5.1.6. Control. Barricades are effective in preventing immediate propagation of

explosion by high-velocity, low-angle fragments. However, they provide only limited protection

29 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

against any delayed propagation of explosives caused by a fire resulting from high-angle
firebrands.

C2.2.5.2. Barricaded Intraline Distance (ILD) - 9W1/3 ft [3.57Q1/3 m] - 12 psi [82.7 kPa].
At this distance:

C2.2.5.2.1. Unstrengthened buildings will suffer severe structural damage

approaching total destruction.

C2.2.5.2.2. Personnel will be subject to severe injuries or death from direct blast,
building collapse, or translation.

C2.2.5.2.3. Aircraft will be damaged beyond economical repair both by blast and
fragments. If the aircraft are loaded with explosives, delayed explosions are likely to result from
subsequent fires.

C2.2.5.2.4. Transport vehicles will be damaged heavily, probably to the extent of

total loss.

C2.2.5.2.5. Improperly designed barricades or structures may increase the hazard

from flying debris, or may collapse in such a manner as to increase the risk to personnel and
equipment.

C2.2.5.2.6. Control. Barricading is required. Direct propagation of explosion

between two explosive locations is unlikely when barricades are placed between them to
intercept high-velocity, low-angle fragments. Exposed structures containing high-value,
mission-critical equipment or personnel may require hardening.

C2.2.5.3. Unbarricaded AGM Distance - 11W1/3 ft [4.36Q1/3 m] - 8 psi [55.3 kPa]. At

this distance:

C2.2.5.3.1. Unstrengthened buildings will suffer damage approaching total

destruction.

C2.2.5.3.2. Personnel are likely to be injured seriously due to blast, fragments,

debris, and translation.

C2.2.5.3.3. There is a 15 percent risk of eardrum rupture.

C2.2.5.3.4. Explosives-loaded vessels are likely to be damaged extensively and

delayed propagation of explosion may occur.

C2.2.5.3.5. Aircraft will be damaged heavily by blast and fragments; destruction by

resulting fire is likely.

30 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.5.3.6. Transport vehicles will sustain severe body damage, minor engine
damage, and total glass breakage.

C2.2.5.3.7. Control. Barricading will significantly reduce the risk of propagation of

explosion and injury of personnel by high-velocity, low-angle fragments.

C2.2.5.4. Unbarricaded ILD - 18W1/3 ft [7.14Q1/3 m] - 3.5 psi [24 kPa]. At this distance:

C2.2.5.4.1. Direct propagation of explosion is not expected.

C2.2.5.4.2. Delayed propagation of an explosion may occur at the ES, as either a

direct result of a fire or as a result of equipment failure.

C2.2.5.4.3. Damage to unstrengthened buildings may approximate 50 percent, or

more, of the total replacement cost.

C2.2.5.4.4. There is a two percent chance of eardrum damage to personnel.

C2.2.5.4.5. Personnel may suffer serious injuries from fragments, debris, firebrands,
or other objects.

C2.2.5.4.6. Fragments could damage the decks and superstructure of cargo ships and
overpressure could buckle their doors and bulkheads on weather decks.

C2.2.5.4.7. Aircraft can be expected to suffer considerable structural damage from

blast. Fragments and debris are likely to cause severe damage to aircraft at distances calculated
from the formula 18W1/3 [7.2Q1/3] when small quantities of explosives are involved.

C2.2.5.4.8. Transport vehicles will incur extensive, but not severe, body and glass
damage consisting mainly of dishing of body panels and cracks in shatter-resistant window glass.

C2.2.5.4.9. Control. Suitably designed suppressive construction at PES or protective

construction at ES may be practical for some situations. Such construction is encouraged when
there is insufficient distance to provide the required protection.

C2.2.5.5. Public Traffic Route Distance (PTRD) (under 100,000 lbs of High Explosives
(HE)) 24W1/3 ft [9.52Q1/3 m] - 2.3 psi [15.8 kPa]. At this distance:

C2.2.5.5.1. Unstrengthened buildings can be expected to sustain damage

approximately 20 percent of the replacement cost.

C2.2.5.5.2. Occupants of exposed structures may suffer temporary hearing loss or

injury from blast effects, building debris and displacement.

C2.2.5.5.3. Although personnel in the open are not expected to be killed or seriously
injured by blast effects, fragments and debris may cause some injuries. The extent of these

31 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

injuries depends largely upon the PES structure and the amount and fragmentation characteristics
of the AE involved.

C2.2.5.5.4. Vehicles on the road should suffer little damage, unless they are hit by a
fragment or the blast causes a momentary loss of control.

C2.2.5.5.5. Aircraft may suffer some damage to the fuselage from blast and possible
fragment penetration, but should be operational with minor repair.

C2.2.5.5.6. Cargo-type ships should suffer minor damage to deck structure and
exposed electronics from blast and possible fragment penetration, but such damage should be
readily repairable.

C2.2.5.5.7. Control. Barricading can reduce the risk of injury or damage due to
fragments for limited quantities of AE at a PES. When practical, suitably designed suppressive
construction at the PES or protective construction at the ES may also provide some protection.

C2.2.5.6. PTRD (over 250,000 lbs HE) 30W1/3 ft [11.9Q1/3 m] - 1.7 psi [11.7 kPa]. At
this distance:

C2.2.5.6.1. Unstrengthened buildings can be expected to sustain damage that may

approximate 10 percent of their replacement cost.

C2.2.5.6.2. Occupants of exposed, unstrengthened structures may be injured by

secondary blast effects, such as falling building debris.

C2.2.5.6.3. Pilots of aircraft that are landing or taking off may lose control and crash.

C2.2.5.6.4. Parked military and commercial aircraft will likely sustain minor damage
due to blast, but should remain airworthy.

C2.2.5.6.5. Although personnel in the open are not expected to be killed or seriously
injured by blast effects, fragments and debris may cause some injuries. The extent of these
injuries will largely depend upon the PES structure, the NEW, and the fragmentation
characteristics of the AE involved.

C2.2.5.6.6. Control. Barricading or the application of minimum fragmentation

distance requirements may reduce the risk of injury or damage due to fragments for limited
quantities of AE at a PES.

C2.2.5.7. Inhabited Building Distance (IBD) 40W1/3 ft - 50W1/3 ft [15.87Q1/3 - 19.8Q1/3

m] - 1.2 psi - 0.90 psi [8.3 kPa - 6.2 kPa]. At this distance:

C2.2.5.7.1. Unstrengthened buildings can be expected to sustain damage that

approximates five percent of their replacement cost.

32 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.5.7.2. Personnel in buildings are provided a high degree of protection from

death or serious injury; however, glass breakage and building debris may still cause some
injuries.

C2.2.5.7.3. Personnel in the open are not expected to be injured seriously by blast
effects. Fragments and debris may cause some injuries. The extent of injuries will depend upon
the PES structure and the NEW and fragmentation characteristics of the AE involved.

C2.2.5.7.4. Control. Elimination of glass surfaces is the best control. If determined

to be necessary, reducing the use of glass or the size of any glass surfaces and the use of blast-
resistant glass will provide some relief. For new construction, building design characteristics
should include consideration of how any required glass surfaces are oriented and use of blast-
resistant glass to reduce glass breakage and structural damage.

C2.3. HD 1.2 EFFECTS

C2.3.1. Blast

C2.3.1.1. HD 1.2, when not stored with HD 1.1 or HD 1.5, is not expected to mass
detonate. In an incident involving HD 1.2, when stored by itself or with HD 1.3, HD 1.4, or HD
1.6 (a HD 1.2 event), AE can be expected to both explode sporadically and burn. Fire will
propagate through the mass of the AE over time. Some AE may neither explode nor burn. Blast
effects from the incident are limited to the immediate vicinity and are not considered to be a
significant hazard.

C2.3.1.2. An HD 1.2 event may occur over a prolonged period of time. Generally, the
first reactions are relatively nonviolent and, typically, begin a few minutes after flames engulf
the AE. Later reactions tend to be more violent. Reactions can continue for some time (hours),
even after a fire is effectively out. Generally, smaller AE tends to react earlier in an incident
than larger AE.

C2.3.1.3. The results of an accidental explosion in an underground facility will depend

on the type and quantity of munitions, the type of explosion produced, and the layout of the
facility. Hazards created outside the underground facility will likely not be as severe as those
produced by HD 1.1 or 1.3 material.

C2.3.2. Fragments

C2.3.2.1. The primary hazard from a HD 1.2 event is fragmentation. Fragmentation may
include primary fragments from AE casings or secondary fragments from containers and
structures. At longer ranges, primary fragments are the major contributors to fragment hazards.

C2.3.2.2. During a HD 1.2 event, fragmentation may extensively damage exposed

facilities. However, less fragmentation damage can be expected from a given quantity of HD 1.2

33 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

than would be expected from the corresponding quantity of HD 1.1 because not all the HD 1.2
will react.

C2.3.3. Thermal Hazards

C2.3.3.1. An incident involving a quantity of HD 1.2 poses considerably less thermal

risk to personnel than an incident involving corresponding quantities of either HD 1.1 or HD 1.3
because a HD 1.2 event’s progressive nature allows personnel to immediately evacuate the area.

C2.3.3.2. A HD 1.2 event’s progressive nature provides an opportunity for a fire

suppression system, if installed, to put out a fire in its early stages.

C2.3.4. Ejected Items. In HD 1.2 events, a reaction may eject (lob) unreacted-AE or AE
components from the event site. These ejected items may subsequently react.

C2.3.5. Propelled Items. In HD 1.2 events, some AE or AE components may become

propulsive and travel well beyond IBD.

C2.3.6. Firebrands. In an incident involving only HD 1.2 or HD 1.2 with HD 1.4,

firebrands are considered to be a hazard only in the immediate vicinity of the incident site.

C2.3.7. Expected Consequences

C2.3.7.1. The expected consequences for HD 1.2 AE are similar to those for HD 1.1.
The effects of HD 1.2 AE are NEW dependent.

C2.3.7.2. The principal hazard to personnel in the open, to aircraft, and to occupied
vehicles is fragments.

C2.3.7.3. Airblast, fragment, and thermal hazards to buildings and parked aircraft or
vehicles cannot be predicted reliably because the effects will depend on the MCE.

C2.4. HD 1.3 EFECTS

C2.4.1. Gas Pressures. In an incident involving only HD 1.3 or HD 1.3 with HD 1.4 (a HD
1.3 event):

C2.4.1.1. Where sufficient venting is provided, gas pressures generated by the event are
not a significant concern. Examples of sites with sufficient venting include open storage and
structures where internal pressures do not exceed 1-2 psi [6.9-13.8 kPa] (non-confinement
structure).

C2.4.1.2. Where venting is insufficient, internal gas pressures may be substantial.

In such situations, these pressures may blow out vent panels or frangible walls and, in some
instances, cause partial or complete structural failure.

34 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.4.1.3. Where there is minimal venting and structural containment (extreme

confinement), a detonation of the HD 1.3 may occur with effects similar to those of a HD 1.1
explosion. For example, HD 1.3 AE is considered as HD 1.1 (mass explosion) for QD purposes
when stored in underground chambers.

C2.4.2. Fragments. In an HD 1.3 event, fragments are considerably less hazardous than
those produced by HD 1.1 and HD 1.2 events. Internal gas pressures may produce fragments
from the bursting of containers or the rupture of containment facilities. In general, such
fragments will be large and of low velocity. (For exceptions, see subparagraph C2.4.1.3.)

C2.4.3. Thermal Hazards. In an HD 1.3 event, heat flux presents the greatest hazard to
personnel and assets. Energetic materials in HD 1.3 articles include both fuel components and
oxidizers. Burning these materials emits fuel-rich flammable gases, fine particles, or both. This
unburned material may ignite when it comes in contact with air and cause a large fireball. This
fireball will expand radially from the ignition site and could wrap around obstacles, even those
designed to provide line-of-sight protection from HD 1.1 events. Shields and walls can be
designed to provide protection from thermal effects (see Chapter 4).

C2.4.3.1. The nominal spherical fireball that would be expected from the rapid burning
of HD 1.3 can be calculated by DFIRE = 10 x WEFF1/3 where “DFIRE” is the diameter of the
fireball (ft) and “WEFF” is the quantity of HD 1.3 involved (lb), multiplied by a 20 percent safety
factor (e.g., “W” of 100 pounds = “WEFF”of 120 pounds) [DFIRE (meters) = 3.97 x WEFF
(kilograms) 1/3].

C2.4.3.2. In addition to the fireball itself, the thermal flux from the fireball can ignite
fires out to Intermagazine Distance (IMD).

C2.4.4. Propelled Items. In an HD 1.3 event, some AE or AE components may become

propulsive and travel well beyond IBD.

C2.4.5. Firebrands. In an HD 1.3 event, a severe fire-spread hazard may result from
firebrands projected from the incident site. Firebrands can be expected to be thrown more than
50 ft [15.2 m] from a HD 1.3 event. Firebrands can ignite fires well beyond the distance to
which a fireball poses a threat.

C2.4.6. Expected Consequences

C2.4.6.1. Exposed personnel may receive severe burns from fireballs or flash burning in
an HD 1.3 event. The hazard distance is dependent on the quantity and burning rate of the HD
1.3 involved.

C2.4.6.2. Buildings, vehicles, and aircraft may be ignited by radiant heat, sparks, or
firebrands or may be damaged by heat (searing, buckling, etc.).

35 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.4.6.3. Personnel in nearby buildings, vehicles, or aircraft may be injured unless

evacuated before heat conditions reach hazardous levels.

C2.5. HD 1.4 EFFECTS

C2.5.1. Blast. There is no blast associated with an incident involving only HD 1.4
(an HD 1.4 event).

C2.5.2. Fragmentation. An HD 1.4 event will not produce fragments of appreciable energy
(i.e., greater than 14.8 ft-lbs [20 joules]). Fragments from HD 1.4S have energies less than or
equal to 5.9 ft-lbs [8 joules].

C2.5.3. Thermal Hazard. AE given this designation are considered to provide only a
moderate fire hazard. A fireball or jet of flame may extend 3 feet [1 m] beyond the location of
the HD 1.4 event. A burning time of less than 330 seconds (5.5 minutes) for 220 lbs [100 kg] of
the HD 1.4 AE is expected.

C2.5.4. Firebrands. No fiery projections are expected beyond 50 feet [15.2 m].

C2.5.5. Compatibility Group (CG) -S Items. HD 1.4 AE assigned a CG-S designation (see
subparagraph C3.2.2.1.13.) is the most benign of all AE. In an HD 1.4 event that only involves
CG-S, the expected blast, thermal, and projection effects will not significantly hinder fire
fighting or other emergency responses.

C2.5.6. Expected Consequences. There may be minor consequences (projection, fire,

smoke, heat, or loud noise) beyond the AE itself.

C2.6. HD 1.5 EFFECTS

HD 1.5 effects are similar to those produced by HD 1.1, without the fragmentation effects.

C2.7. HD 1.6 EFFECTS

HD 1.6 effects are similar to those produced by HD 1.3.

DoD 6055.09-STD, February 29, 2008

C3. CHAPTER 3
HAZARD CLASSIFICATION,
STORAGE AND COMPATIBILITY PRINCIPLES,
AND MIXING RULES

C3.1. HAZARD CLASSIFICATION

To ease identification of hazard characteristics for storage and transportation, the Department of
Defense shall use:

C3.1.1. DoD Ammunition and Explosives Hazard Classification Procedures as a basis for
assigning hazard classifications to all AE for both storage and transportation applications. (See
Technical Bulletin (TB) 700-2, Naval Sea Systems Command Instruction (NAVSEAINST)
8020.8B, Technical Order (TO) 11A-1-47, Defense Logistics Agency Regulation (DLAR)
8220.1 (Reference (d)).

C3.1.2. The applicable Department of Transportation (DoT) hazardous materials regulations

per 49 Code of Federal Regulations (CFR) parts 171 to 177 (Reference (e)).

C3.1.3. The United Nations’ (UN) international system of classification developed for the
transport of dangerous goods. See ST/SG/AC.10 (Reference (f)).

C3.2. DOD HAZARD CLASSIFICATION SYSTEM

C3.2.1. The DoD hazard classification system consists of nine hazard classes plus a non-
regulated category that applies when explosives and hazardous materials are present in an item,
but not to the degree that criteria for assignment to one of the nine classes are met. AE is
assigned to the class that represents an item’s predominant hazard characteristic. Class 1 applies
to AE where the explosive hazard predominates. The six Class 1 divisions, and three division
1.2 subdivisions (subdivisions are only applicable for storage applications), which are outlined
below, are used to indicate the character and predominance of explosive hazards. In addition to
the classes, divisions, subdivisions, and the non-regulated category, thirteen Compatibility
Groups (CG) are used for segregating AE on the basis of similarity of function, features, and
accident effects potential. Furthermore, a parenthetical number is also used to indicate the
minimum separation distance (in hundreds of feet) for protection from debris, fragments, and
firebrands, when distance alone is relied on for such protection. This number is placed to the left
of the hazard classification designators 1.1 through 1.3 (e.g., (18)1.1, (08)1.2.3, or (02)1.3). To
simply express an item’s hazard classification, this Standard uses the term “Hazard Division
(HD)” to avoid repeatedly using the more cumbersome terminology “Subdivision X of Division
Y of Class Z.” The six Class 1 divisions and three hazard subdivisions are:

C3.2.1.1. Mass explosion (HD 1.1).

C3.2.1.2. Non-mass explosion, fragment producing (HD 1.2). (See paragraph C9.4.2.)

37 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

C3.2.1.2.1. HD 1.2.1. Those items with a NEWQD > 1.60 pounds [0.73 kg] or that
exhibit fragmentation characteristics similar to or greater than (higher density, longer distance)
M1 105 mm projectiles regardless of NEWQD.

C3.2.1.2.2. HD 1.2.2. Those items with an NEWQD < 1.60 pounds [0.73 kg] or that
at most exhibit fragmentation characteristics similar to high-explosive 40 mm ammunition
regardless of NEWQD.

C3.2.1.2.3. HD 1.2.3. AE that exhibits at most an explosion reaction in the

sympathetic reaction test, and no reaction more severe than burning in the liquid fuel/external
fire test, bullet impact test, and slow heating test.

C3.2.1.3. Mass fire, minor blast or fragment (HD 1.3).

C3.2.1.4. Moderate fire, no significant blast or fragment (HD 1.4).

C3.2.1.5. Explosive substance, very insensitive (with mass explosion hazard) (HD 1.5).

C3.2.1.6. Explosive article, extremely insensitive (no mass explosion hazard) (HD 1.6).

C3.2.2. Storage and Transportation CG

C3.2.2.1. The thirteen CG assigned to AE based on similarity of function, features, and

accident effects potential are:

C3.2.2.1.1. Group A. Initiating (primary) explosives. Bulk initiating explosives that

have the necessary sensitivity to heat, friction, or percussion to make them suitable for use as
initiating elements in an explosive train. Examples include the following: bulk lead azide, lead
styphnate, mercury fulminate, tetracene, dry cyclotrimethylenetrinitramine (RDX) (also known
as cyclonite, hexogen, or Royal Demolition Explosive), and dry pentaerythritol tetranitrate
(PETN).

C3.2.2.1.2. Group B. Detonators and similar initiating devices not containing two or
more effective protective features. Items containing initiating (primary) explosives that are
designed to initiate or continue the functioning of an explosive train. Examples include the
following: detonators, blasting caps, small arms primers, and fuzes.

C3.2.2.1.3. Group C. Bulk propellants, propelling charges, and devices containing

propellant with, or without, its own means of ignition. Examples include the following: bulk
single-, double-, or triple-base, and composite propellants, rocket motors (solid propellant), and
propelled AE with inert projectiles.

C3.2.2.1.4. Group D. Bulk black powder; bulk HE (secondary explosives); and AE

without a propelling charge, but containing HE (secondary explosives) without its own means of
initiation, i.e., no initiating device is present or the device has two or more effective protective
features. Examples include the following: bulk trinitrotoluene (TNT), Composition B, and black

38 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

powder; bulk wet RDX or PETN; bombs, projectiles, Cluster Bomb Units (CBU), depth charges,
and torpedo warheads.

C3.2.2.1.5. Group E. AE containing HE (secondary explosives) without its own

means of initiation and either containing, or with, a solid propelling charge. Examples include
the following: artillery AE, rockets, and guided missiles.

C3.2.2.1.6. Group F. AE containing HE (secondary explosives) with its own means

of initiation, i.e., the initiating device present has less than two effective protective features, and
with or without a solid propelling charge. Examples include the following: grenades, sounding
devices, and similar items having explosive trains with less than two effective protective
features.

C3.2.2.1.7. Group G. Illuminating, incendiary, and smoke- (including

hexachlorethane (HC)) or tear-producing AE, excluding those that are water-activated or that
contain white phosphorus (WP) or a flammable liquid or gel. Examples include the following:
flares, signals, and pyrotechnic substances.

C3.2.2.1.8. Group H. AE containing WP. AE in this group contains fillers that are
spontaneously flammable when exposed to the atmosphere. Examples include the following:
WP and plasticized white phosphorus (PWP).

C3.2.2.1.9. Group J. AE containing flammable liquids or gels other than those that
are spontaneously flammable when exposed to water or the atmosphere. Examples include the
following: liquid- or gel-filled incendiary AE, Fuel-Air Explosive (FAE) devices, and
flammable liquid-fueled missiles and torpedoes.

C3.2.2.1.10. Group K. AE containing toxic chemical agents. AE in this group

contain chemicals specifically designed for incapacitating effects more severe than lachrymation
(tear-producing). Examples include the following: artillery or mortar AE (fuzed or unfuzed),
grenades, rockets and bombs filled with a lethal or incapacitating chemical agent. (See note 4,
Table C3.T1.)

C3.2.2.1.11. Group L. AE not included in other CG, having characteristics that

present a special risk that does not permit storage with other types of AE, or other kinds of
explosives, or dissimilar AE of this group. Examples include the following: water-activated
devices, pyrophorics and phosphides and devices containing these substances, prepackaged
hypergolic liquid-fueled rocket engines, triethyl aluminum (TEA), thickened TEA (TPA), and
damaged or suspect AE of any group. Different types of AE in CGL presenting similar hazards
may be stored together.

C3.2.2.1.12. Group N. AE containing only Extremely Insensitive Detonating

Substances (EIDS). An example is HD 1.6 AE.

C3.2.2.1.13. Group S. AE that presents no significant hazard, packaged or designed

so that any hazardous effects from accidental functioning are limited to the extent that they do

39 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

not significantly hinder firefighting. Examples include the following: explosive switches or
valves and small arms ammunition.

C3.2.3. Sensitivity Groups (SG). For the purpose of storage within a HPM (see paragraph
C3.3.7.) or where ARMCO, Inc. revetments (see paragraph C5.3.5.) or Substantial Dividing
Walls (SDW) are utilized to reduce MCE, each HD 1.1 and HD 1.2 AE item is designated, based
on its physical attributes, into one of five SG. Directed energy weapons are further identified by
assigning the suffix “D” following the SG designation (e.g., SG2D). The SG assigned to an HD
1.1 and HD 1.2 AE item is found in the Joint Hazard Classification System (JHCS).

C3.2.3.1. The five SG, in relative order from least sensitive to most sensitive, are:

C3.2.3.1.1. SG 2: Non-robust or thin-skinned AE (see glossary).

C3.2.3.1.2. SG 1: Robust or thick-skinned AE. A SG 1 item meets any two of the

following criteria:

C3.2.3.1.2.1. Ratio of explosive weight to empty case weight < 1.

C3.2.3.1.2.2. Minimum case thickness > 0.4 inches [1 cm].

C3.2.3.1.2.3. Ratio of case thickness to NEWQD1/3 > 0.05 in/lb1/3 [0.165

cm/kg1/3].

C3.2.3.1.3. SG 3: Fragmenting AE. These items, which are typically air-to-air

missiles, have warhead cases designed for specific fragmentation (e.g., pre-formed fragment
warhead, scored cases, and continuous rod warheads).

C3.2.3.1.4. SG 4: Cluster bombs/dispenser munitions.

C3.2.3.1.5. SG 5: Other AE (items for which HPM non-propagation walls are not
effective). Items are assigned to SG 5 because they are either very sensitive to propagation or
their sensitivity has not been determined.

C3.2.3.2. Item-specific testing or analyses can be used to change an item’s SG.

C3.3. STORAGE AND COMPATIBILITY PRINCIPLES

C3.3.1. Separate storage of AE by HD and type provides the highest degree of safety.
Because such storage is generally not feasible, mixed storage—subject to compliance with these
Standards—is normally implemented when such storage facilitates safe operation and promotes
overall storage efficiency.

40 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

C3.3.2. The CG assigned to AE indicates what it can be stored with or without significantly
increasing either an accident’s probability or, for a given quantity, the magnitude of an accident’s
effects. Only compatible AE will be stored together.

C3.3.3. AE may not be stored with dissimilar substances or articles (e.g., flammable or
combustible materials, acids, or corrosives) that may present additional hazards to the AE unless
they have been assessed to be compatible. Non-Regulated AE and AE assigned to Classes 2
through 9 may have a CG assigned. When so assigned, the AE may be stored in an explosives
magazine in accordance with the CG. The explosive weight of non-regulated AE and AE
assigned to Classes 2 through 9 is not considered for QD purposes.

C3.3.4. The DoD hazard classification system classifies articles that contain riot control
substances, without explosives components, and bulk toxic chemical agents as HD 6.1.

C3.3.5. AE in damaged packaging, in a suspect condition, or with characteristics that

increase risk in storage, are not compatible with other AE and will be stored separately (in CG
L).

C3.3.6. If different types of CG N munitions are mixed together and have not been tested to
ensure non-propagation, the mixed munition types are individually considered to be HD 1.2.1 D
or HD 1.2.2 D based on their NEWQD or overriding fragmentation characteristics.

C3.3.7. High Performance Magazine. Because of its construction (see paragraph C5.2.4.),
each HPM storage cell is treated as a separate magazine for the purposes of meeting
compatibility and mixing requirements. Within a HPM cell, all current compatibility and mixing
regulations apply. The maximum allowable NEWQD is 30,000 lbs [13,608 kg] in a HPM cell
and 60,000 lbs [27,215 kg] in the loading dock with the following restraints:

C3.3.7.1. When SG 1, 2, or 3 AE is present in a HPM cell, the allowable NEWQD in all

cells (adjacent, across, and diagonal) and in the loading dock remains the maximum.

C3.3.7.2. When SG 4 AE is present in a HPM cell, the allowable NEWQD in each

adjacent cell and in the cell directly across from it is reduced to 15,000 lbs [6,804 kg]. The
allowable NEWQD in diagonal cells and in the loading dock remains the maximum.

C3.3.7.3. When SG 5 AE is present in a HPM, the NEWQD of all cells and the loading
dock must be summed for quantity-distance purposes.

C3.3.7.4. When directed energy weapons are present in a HPM, they must be oriented in
such a manner that if initiation were to occur, the consequences would be directed away from
any other cell. Otherwise, the NEWQD of all cells and the loading dock must be summed for
quantity-distance purposes.

C3.3.7.5. When HD and SG are mixed within a HPM cell, the most sensitive SG
associated with the AE in that cell controls the allowable NEWQD in each adjacent cell. For

41 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

example, when HD 1.3, HD 1.4 and HD 1.6 items are stored with HD 1.1 or HD 1.2 items, the
most sensitive SG of the HD 1.1 and HD 1.2 items controls the storage requirements.

C3.4. MIXED COMPATIBILITY GROUP STORAGE

C3.4.1. AE of different CG may only be mixed in storage as indicated in Table C3.T1. The
exceptions are when Chapter 10 is being applied, and at specific continental United States
(CONUS) locations that a DoD Component designates to store AE packaged and configured for
rapid response (e.g., Rapid Deployment Force) for which the DDESB has approved the site plan.
Such designated locations are authorized to mix CG, without complying with the compatibility
and mixing requirements, as operationally required to achieve the optimum load needed by the
intended receiving troops. The MCE allowable at any of these storage sites shall be limited to
8,818 lbs NEWQD [4,000 kg NEQ]. When computing QD requirements for such sites, Chapter
9 applies. However, the following AE will be excluded for NEWQD determination at such
storage sites:

C3.4.1.1. Propelling charges in HD 1.2 fixed, semi-fixed, mortar, and rocket AE (see
glossary).

C3.4.1.2. The NEWQD of HD 1.3 items, except at sites that contain only HD 1.3 items.
At such sites, HD 1.3 QD applies. (NOTE: In the application of this paragraph to separate
loading AE, the explosive weight of propelling charges is generally excluded when matched
pairs of projectiles and propelling charges are at the site. However, if the quantity of propelling
charges at the site exceeds the maximum usable for the quantity of projectiles at the site, the
explosive weights of all propelling charges and projectiles at the site must be summed for
NEWQD determination.)

Notes for Table C3.T1.:
1 An “X” at an intersection indicates that the groups may be combined in storage. Otherwise, mixing is either
prohibited or restricted per Note 2.
2 A “Z” at an intersection indicates that when warranted by operational considerations or magazine non-
availability, and when safety is not sacrificed, mixed storage of limited quantities of some items from
different groups may be approved by the DoD Components. Such approval documentation must be kept on
site. Component approval of mixed storage in compliance with Z intersections does not require a waiver or
exemption. Mixed storage of items within groups where no X or Z exists at that pair’s intersection beyond
the prohibitions and limitations of Note 7, however, requires an approved waiver or exemption.
Examples of acceptable storage combinations are:
a. HD 1.1A initiating explosives with HD 1.1B fuzes not containing two or more effective protective
features.
b. HD 1.3C bulk propellants or bagged propelling charges with HD 1.3G pyrotechnic substances.
3 Equal numbers of separately packaged components of hazard-classified complete rounds of any single type
of AE may be stored together. When so stored, compatibility is that of the complete round.
4 CG K requires not only separate storage from other groups, but also may require separate storage within the
group. The controlling DoD Component will determine which items under CG K may be stored together
and those that must be stored separately. Such documentation must be kept on site.
5 AE classed outside Class 1 may be assigned the same CG as Class 1 AE containing similar hazard features,
but where the explosive hazard predominates. Non-Class 1 AE and Class 1 AE assigned the same CG may
be stored together.
6 The DoD Components may authorize AE-designated “Practice” or “Training” by nomenclature, regardless
of the CG assigned, to be stored with the tactical AE it simulates. Such documentation must be kept on site.
7 The DoD Components may authorize the mixing of CG, except items in CG A, K and L, in limited
quantities generally of 1,000 lb [454 kg] total NEWQD or less. Such documentation must be kept on site.
8 For purposes of mixing, all AE must be packaged in its standard storage and shipping container. AE
containers will not be opened for issuing items from storage locations. Outer containers may be opened in
storage locations for inventorying and for magazines storing only HD 1.4 items, unpacking, inspecting, and
repackaging the HD 1.4 ammunition.
9 When using the “Z” mixing authorized by Note 2 for articles of either CG B or CG F, each will be
segregated in storage from articles of other CG by means that prevent propagation of CG B or CG F articles
to articles of other CG.
10 If dissimilar HD 1.6N AE are mixed together and have not been tested to ensure non-propagation, the mixed
AE are individually considered to be HD 1.2.1 D or HD 1.2.2 D based on their NEWQD or overriding
fragmentation characteristics for purposes of transportation and storage. When mixing CG N AE with CG
B through CG G or with CG S, see subparagraphs C9.2.2.1.1., C9.2.2.4., C9.2.2.10., and C9.2.2.11. to
determine the HD for the mixture.

C4. CHAPTER 4
PERSONNEL PROTECTION

C4.1. SCOPE AND APPLICATION

This chapter establishes blast, fragment, and thermal hazards protection principles. It applies to
all operations and facilities within an Explosives Safety Quantity-Distance (ESQD) arc in which
personnel are exposed to AE hazards. Technical Manual (TM)-5-1300, Naval Facilities
Engineering Command (NAVFAC) P-397, Air Force Manual (AFM) 88-22 (Reference (g))
contains design procedures to achieve personnel protection, protect facilities and equipment, and
prevent propagation of explosions.

C4.2. RISK ASSESSMENT

The responsible DoD Component shall perform a risk assessment on new or modified operations
and facilities involving AE. Based upon such an assessment, engineering design criteria for
facilities and operations shall be developed for use in the selection of equipment, shielding,
engineering controls, and protective clothing for personnel.

C4.2.1. The risk assessment shall include:

C4.2.1.1. Initiation sensitivity.

C4.2.1.2. Quantity of materials.

C4.2.1.3. Heat output.

C4.2.1.4. Rate of burn.

C4.2.1.5. Potential ignition and initiation sources.

C4.2.1.6. Protection capabilities of shields, various types of clothing, and fire protection
systems.

C4.2.1.7. Personnel exposure.

C4.2.2. New or modified facilities, located within the IBD arc of any PES, that will include
glass panels and will contain personnel, shall have a glass breakage personnel hazards risk
assessment conducted.

C4.3. PERMISSIBLE EXPOSURES

C4.3.1. Accidental Ignition or Initiation of Explosives.

43 CHAPTER 4
DoD 6055.09-STD, February 29, 2008

C4.3.1.1. When a risk assessment indicates that there is an unacceptable risk from an
accidental explosion or a flash fire, personnel shall be provided protection from blast, fragments,
and thermal effects, to include respiratory and circulatory hazards.

C4.3.1.2. When required, personnel protection must limit incident blast overpressure to
2.3 psi [15.9 kPa], fragments to energies of less than 58 ft-lb [79 joules], and thermal fluxes to
0.3 calories per square centimeter per second [12.56 kilowatts per square meter].

C4.3.1.3. K24 [9.52] distance provides the required level of protection for blast and
thermal effects only.

C4.3.1.4. Shields that comply with Military Standard (MIL-STD)-398 (Reference (h))
provide acceptable protection for blast, thermal and fragment effects.

C4.3.2. Intentional Ignition or Initiation of AE. At operations (e.g., function, proof, lot
acceptance testing) where intentional ignition or initiation of AE are conducted and where
shielding is required, as determined on a case-by-case basis by the DoD Component concerned,
personnel protection shall:

C4.3.2.1. Meet the requirements of subparagraph C4.3.1.2.

C4.3.2.2. Limit overpressure levels in personnel-occupied areas to satisfy MIL-STD-

1474D (Reference (i)).

C4.3.2.3. Contain or defeat all fragments.

C4.3.2.4. Limit thermal flux to: “Q” (calories/square centimeter/second) = 0.62t-0.7423

where “t” is the time in seconds that a person is exposed to the radiant heat. (Shields that comply
with Reference (h) provide acceptable protection.)

C4.4. PROTECTIVE MEASURES

Personnel protection may be achieved by:

C4.4.1. Eliminating or establishing positive control of ignition and initiation stimuli.

C4.4.2. Using sufficient distance or barricades to protect from blast or fragments.

C4.4.3. Using fire detection and extinguishing systems (e.g., infra-red (IR) actuated deluge
system) in those areas where exposed, thermally-energetic materials that have a high probability
of ignition and a large thermal output are handled. Such systems shall maximize the speed of
detection, have adequate capacity to extinguish potential flash fires in their incipient state, and
maximize the speed of the application of the extinguishing agent.

44 CHAPTER 4
DoD 6055.09-STD, February 29, 2008

C4.4.4. Using thermal shielding between the thermal source and personnel in AE operational
areas, where it is essential for personnel to be present and the risk assessment indicates that an
in-process thermal hazard exists. Any shielding used shall comply with Reference (h). When
shielding is either not possible or inadequate, to include a failure to protect exposed personnel’s
respiratory and circulatory systems, augmentation with improved facility engineering design and
personnel protective clothing and equipment may be necessary.

C4.4.5. Using thermal protective clothing that is capable of limiting bodily injury to first
degree burns (0.3 calories per square centimeter per second [12.56 kilowatts/m2]) with personnel
taking turning-evasive action, when the maximum quantity of combustible material used in the
operation is ignited.

C4.4.6. Using protective clothing capable of providing respiratory protection from the
inhalation of hot vapors or any toxicological effects, when the risk assessment indicates adverse
effects would be encountered from the inhalation of combustion products.

C4.4.7. Minimizing the number and size of glass panels in an ES and, if possible, orienting
the ES to minimize blast loads on glass panels, when a risk assessment (see section C4.2.)
indicates that a glass hazard is present.

C4.4.7.1. When use of window panels is determined to be necessary and a risk

assessment determines that there will be an associated glass hazard, blast-resistant windows of
sufficient strength, as determined by an engineering analysis, shall be used for:

C4.4.7.1.1. Existing ES, upon major modification or modified operations.

C4.4.7.1.2. New construction. (The use of glass panels in new construction should
be avoided.)

C4.4.7.2. The framing and sash of such panels shall be of sufficient strength to retain the
panel in the structure for the expected blast loads from an explosion at any PES.

DoD 6055.09-STD, February 29, 2008

C5. CHAPTER 5
CONSTRUCTION CRITERIA PERMITTING REDUCED SEPARATION DISTANCES

C5.1. GENERAL

C5.1.1. This chapter contains DoD standards for construction of ECM, barricades,
barricaded open storage modules, special structures, ARMCO, Inc. revetments, and underground
storage facilities. Facilities constructed per this chapter:

C5.1.1.1. Are permitted to use reduced separation distance criteria.

C5.1.1.2. Must meet the criteria of Chapters 6 and 7.

C5.1.2. Construction features and location are important safety considerations in planning
facilities. The effects of potential explosions may be altered significantly by construction
features that limit the amount of explosives involved, attenuate blast overpressure or thermal
radiation, and reduce the quantity and range of hazardous fragments and debris. (NOTE: Proper
location of ES in relation to PES helps minimize unacceptable damage and injuries in the event
of an incident.) The major objectives in facility planning shall be to:

C5.1.2.1. Protect against explosion propagation between adjacent bays or buildings and
protect personnel against death or serious injury from incidents in adjacent bays or buildings.
The construction of separate buildings to limit explosion propagation, rather than the use of
either protective construction or separation of explosives within a single building should be
considered when safety would be greatly enhanced or cost would be significantly reduced.

C5.1.2.2. Protect assets, when warranted.

C5.1.3. Hardening an ES or constructing a PES to suppress explosion effects to provide an

appropriate degree of protection may allow a reduction of the separation distances required by
QD tables. The rationale and supporting data that justify any such QD reduction shall be
submitted to the DDESB with the site and general construction plans for approval (see section
C5.4.).

C5.1.4. New construction of previously DDESB-approved 7-Bar and 3-Bar ECM must meet
the minimum requirements of the current revisions of the approved drawings.

C5.2. AE STORAGE FACILITIES

C5.2.1. ECM. An ECM’s primary purpose is to protect AE. To qualify for the default IMD
in Table C9.T6., an ECM, acting as an ES, must not collapse. Although substantial permanent
deformation of the ECM may occur, sufficient space should be provided to prevent the deformed
structure or its doors from striking the contents.

46 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.1.1. ECM may be approved for storage of up to 500,000 lbs NEW [226,795 kg
NEQ] of HD 1.1 in accordance with Table C9.T5. DDESB Technical Paper (TP) No. 15,
(Reference (j)) provides listings of the various types of ECM that have been constructed. These
magazines are identified by their structural strength designator (i.e. 7-Bar, 3-Bar, or Undefined).
Table AP1-1. of Reference (j) lists the 7-Bar and 3-Bar ECM designs that are currently approved
for new construction.

C5.2.1.1.1. If an ECM’s drawing number(s) are not listed in Reference (j), it shall be
treated as an “Undefined” ECM, until a structural analysis is performed to show that the ECM
qualifies for another structural strength designation, or support documentation is provided to
prove the ECM had been approved by the DDESB with a different structural strength
designation.

C5.2.1.1.2. For existing, arch-shaped Undefined ECM, U. S. Army Corps of

Engineers (CoE) Report HNDED-CS-S-95-01 (Reference (k)) may be used to determine if an
Undefined ECM could qualify as a 7-Bar or a 3-Bar ECM.

C5.2.1.1.3. DDESB approval is required prior to any change in an ECM’s structural

strength designator.

C5.2.1.1.4. Certain ECM, aboveground storage magazines, and containers have been
approved with reduced NEW and/or reduced QD and these are listed in Table AP1-4. of
Reference (j). Use of these structures/containers requires that their use and siting meet all
conditions AND restrictions specified in the design and approval documentation, as described in
Reference (j).

C5.2.1.2. ECM must be designed to withstand the following:

C5.2.1.2.1. Conventional (e.g., live, dead, snow) loads for the barrel of an
arch-shaped ECM.

C5.2.1.2.2. Conventional (e.g., live, dead, snow) and blast-induced loads for the roof
of a flat-roofed ECM.

C5.2.1.2.3. Conventional (e.g., live, dead, snow) loads for the rear wall of an
arch-shaped ECM and for the rear and side walls of a flat-roofed ECM.

C5.2.1.2.4. Expected blast loads, as applicable:

C5.2.1.2.4.1. On the head wall and door of 3-Bar ES ECM is a triangular pulse
with peak overpressure of 43.5 psi [3 bars, 300 kPa] and impulse of 11.3W1/3 psi-ms [100Q1/3
Pa-s].

C5.2.1.2.4.2. On the head wall and door of 7-Bar ES ECM is a triangular pulse
with peak overpressure of 101.5 psi [7 bars, 700 kPa] and impulse of 13.9W1/3 psi-ms [123Q1/3
Pa-s].

47 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.1.2.4.3. On the roof of a flat-roofed Undefined, 3-Bar, or 7-Bar ES ECM is

a triangular pulse with peak overpressure of 108 psi [7.5 bars, 745 kPa] and impulse of 19W1/3
psi-ms [170Q1/3 Pa-s].

C5.2.1.3. Earth cover for ECM.

C5.2.1.3.1. Earth cover shall be reasonably cohesive and free from harmful (toxic)
matter, trash, debris, and stones heavier than ten pounds [4.54 kg] or larger than six inches [152
mm] in diameter. Solid or wet clay or similar types of soil shall not be used as earth cover
because it is too cohesive. The larger of acceptable stones shall be limited to the lower center of
fills and shall not be used for earth cover over magazines. The earthen material shall be
compacted and prepared, as necessary, for structural integrity and erosion control. If it is
impossible to use a cohesive material (e.g., in sandy soil), the earth cover over ECM shall be
finished with a suitable material (e.g., geotextiles, gunnite) that will ensure structural integrity.

C5.2.1.3.2. The earth fill or earth cover between ECM may be either solid or sloped.
A minimum of 2 ft [0.61 m] of earth cover shall be maintained over the top of each ECM. If the
specified thickness and slope of earth on the ECM is not maintained, the ECM shall be sited as
an AGM.

C5.2.2. Barricaded Open Storage Modules

C5.2.2.1. As depicted in Figure C5.F1., a module is a barricaded area composed of a

series of connected cells with hard surface (e.g., concrete, packed earth, engineered
materials, etc.) storage pads separated from each other by barricades. Although a light metal
shed or other lightweight fire retardant cover may be used for weather protection for individual
cells, heavy structures (e.g., reinforced concrete, dense masonry units), or flammable material
shall not be used.

C5.2.2.2. The maximum NEW [NEQ] permitted to be stored within each cell is 250,000
lbs [113,398 kg].

C5.2.2.3. Module storage is considered a temporary expedient and may be used as the
DoD Component concerned determines necessary. However, from an explosives safety and
reliability standpoint, priority shall be given to the use of ECM for items requiring protection
from the elements, long-term storage, or high security protection.

C5.2.2.4. Storage shall be limited to AE that will not promptly propagate explosions or
mass fire between modules, and that are not susceptible to firebrands and fireballs. These
restrictions allow storage at K1.1 [0.44] separation.

C5.2.2.4.1. Only the following AE are approved for modular storage:

C5.2.2.4.1.1. Robust HD 1.1 AE (e.g., HE bombs, fuzed or unfuzed, with or

without fins) when stored on nonflammable pallets.

48 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.2.4.1.2. The below items when contained in nonflammable shipping

containers:

C5.2.2.4.1.2.1. 30 mm and smaller AE.

C5.2.2.4.1.2.2. CBU.

C5.2.2.4.1.2.3. Inert AE components.

C5.2.2.4.1.2.4. HD 1.4 AE.

C5.2.2.4.2. Module storage of AE items in flammable outer-packaging

configurations shall be minimized. AE items in flammable outer-packaging configurations must
be covered with fire retardant material. Combustible dunnage or other flammable material shall
not be stored either in, or within, 100 ft [30.5 m] of modules.

C5.2.2.4.3. When fire retardant materials are used to cover AE items stored in
modules, ventilation shall be provided between the covers and the stored AE items to minimize
the effects of solar heating upon the stored AE.

C5.2.2.4.4. AE stored in each module shall normally be limited to one type of item,
unless the DoD Component concerned authorizes mixed storage.

C5.2.2.5. Barricade Requirements:

C5.2.2.5.1. All barricades used in forming the module shall meet the requirements in
section C5.3. The width or length of the stack of AE (controlled by the pad size of the cell) and
the distances between the stack and the top of the barricade influences the minimum barricade
height requirement. The heights listed in Table C5.T1. are the minimum requirements for
barricade locations. These minimum heights are based upon both the storage pad sizes and the
separations shown. When feasible, barricade heights should be increased (see subparagraph
C5.3.2.3.).

C5.2.2.5.2. The centerlines of barricades between cells of the module shall be located
at a point halfway between adjacent AE storage pads. Back and end (outside) barricades shall be
located at the same distance from the pads as those between the cells.

C5.2.2.5.3. When selecting a site for a module, maximum advantage should be taken
of natural topographical barriers. When used, natural barriers shall provide the same level of
protection as the barricade shown in Figure C5.F1.

C5.2.2.6. Table C5.T1. provides the minimum pad sizes necessary to store the NEWQD
indicated. The pad’s size may need to be adjusted to accommodate specific AE. This
adjustment will impact the required barricade height (see Note 2 of Table C5.T1.).

49 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.2.7. The only restriction on the arrangement of cells within a module and of groups
of modules is that cell openings may not face each other, unless they are either barricaded or
meet QD criteria for an unbarricaded AGM (see Table C9.T6.).

C5.2.3. Underground Storage Facilities

C5.2.3.1. General Design Considerations

C5.2.3.1.1. Underground storage facilities may consist of a single chamber or a series

of connected chambers and other protective construction features. The chambers may be either
excavated or natural geological cavities. Figure C5.F2. shows the layout of several typical
underground facilities. To qualify as an underground facility, the minimum distance from the
perimeter of a storage area to an exterior surface shall be greater than 0.25 W1/3 [0.10 Q1/3]. This
minimum distance normally, but not always, equals the thickness of the earth cover. If this
criterion cannot be met, the facility must be sited as an AGM.

C5.2.3.1.2. Design of new underground storage facilities must take into account site
conditions, storage requirements, and operational needs. Once these are established, a design
may be developed based on the CoE definitive drawing, DEF 421-80-04, discussed in Chapter 5
of Reference (j). Special features (e.g., debris traps, expansion chambers, closure blocks, portal
barricades, and constrictions) may be incorporated in the design of underground storage facilities
to reduce the IBD for both debris and airblast. The specifications for these special features are
also given in CoE definitive drawing, DEF 421-80-04, and their effects are discussed below.

C5.2.3.2. Special Design Considerations

C5.2.3.2.1. Debris Mitigation. Debris IBD may be reduced through the use of debris
traps, expansion chambers, high pressure closures, and portal barricades.

C5.2.3.2.1.1. Debris traps are pockets excavated in the rock at or beyond the end
of sections of tunnel that are designed to catch debris from a storage chamber detonation. Debris
traps should be at least 20 percent wider and 10 percent taller than the tunnel leading to the trap,
with a depth (measured along the shortest wall) of at least one tunnel diameter.

C5.2.3.2.1.2. Expansion chambers are very effective in entrapping debris, as long

as the tunnels entering and exiting the chambers are either offset in axial alignment by at least
two tunnel widths, or enter and exit the chambers in directions that differ by at least 45 degrees.

C5.2.3.2.1.3. To be effective, debris traps and expansion chambers that are

intended to entrap debris must be designed to contain the full potential volume of debris, based
on the maximum capacity of the largest storage chamber.

C5.2.3.2.1.4. Portal barricades provide a means of reducing IBD from debris by

obstructing the path of the debris as it exits the tunnel.

C5.2.3.2.1.5. High-pressure closures are large blocks constructed of concrete or

other materials that can obstruct or greatly reduce the flow of blast effects and debris from an
explosion from or into a storage chamber. For chamber loading density (w) of about 0.625 lb/ft3
[10 kg/m3] or above, closure blocks will contain 40 percent or more of the explosion debris
within the detonation chamber, provided that the block is designed to remain intact. If a closure
block fails under the blast load, it will produce a volume of debris in addition to that from the
chamber itself. However, because the block’s mass and inertia are sufficient to greatly reduce
the velocity of the primary debris, the effectiveness of other debris-mitigating features (e.g.,
debris traps, expansion chambers, and barricades) is increased.

C5.2.3.2.1.6. Use of barricades with any other of these features will lower the
debris hazard to a level where QD considerations for debris is not required.

C5.2.3.3. Airblast Mitigation. Special features that may be used in underground storage
facilities to reduce airblast IBD include:

C5.2.3.3.1. Facility Layouts. A facility’s layout and its volume control the external
airblast effects.

C5.2.3.3.1.1. In a single-chamber facility with a straight access tunnel leading

from the chamber to the portal, which is commonly called a “shotgun” magazine, the blast and
debris are channeled to the external area as if fired from a long-barreled gun. In this type of
facility design, airblast mitigation, given a fixed NEWQD, can be provided by increased
chamber and tunnel dimensions.

C5.2.3.3.1.2. In more complex facility layouts, reflections of the explosive shock

against the various tunnel walls may reduce the exit pressures. The cumulative effects of these
reflections may reduce the overpressure at the shock front to that of the expanding gas pressure.
In addition, the detonation gas pressure decreases as the volume it occupies increases.
Therefore, larger, more complex facilities will produce greater reductions in the effective
overpressure at the opening, which will reduce the IBD.

C5.2.3.3.1.3. In a more complex facility with two or more openings, the IBD will
be reduced by about 10 percent.

C5.2.3.3.2. Expansion-Chambers. Expansion-chambers provide additional volume

for the expansion of the detonation gasses behind the shock front as it enters the chamber from a
connecting tunnel. Some additional reduction of the peak pressure at the shock front occurs as
the front expands into the expansion-chamber and reflects from the walls. Although expansion-

54 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

chambers may be used as loading areas or as turn-around areas for transport vehicles servicing
facilities through a single entry passage, they shall not be used for storage.

C5.2.3.3.3. Constrictions. Constrictions are short lengths of tunnel whose cross-

sectional areas are reduced to one-half or less of the normal tunnel cross-section. Constrictions
reduce the airblast effects passing through them. To be effective, constrictions should be placed
within five tunnel diameters of the tunnel exit or to the entrances of storage chambers. As an
added benefit, constrictions at chamber entrances also reduce the total loading on blast doors that
may be installed to protect a chamber’s contents.

...... C5.2.3.3.4. Portal Barricades. A barricade in front of the portal (entrance into tunnel)
will reflect that portion of the shock wave moving directly outward from the portal, thereby
reducing the pressures along the extended tunnel axis and increasing the pressures in the opposite
direction. The result is a more circular IBD area centered at the portal. A portal barricade
meeting the construction criteria of the CoE definitive drawing discussed in subparagraph
C5.2.3.1.2. will reduce the IBD along the extended tunnel axis by 50 percent. The total IBD area
is only slightly reduced, but will change to a circular area, half of which is behind the portal.

...... C5.2.3.3.5. High-Pressure Closures. High-Pressure Closures are large blocks

constructed of concrete or other materials that obstruct or greatly reduce the flow of blast effects
and debris from an explosion from or into a storage chamber.

C5.2.3.3.5.1. When used to reduce QD, by restricting the blast outflow from a
chamber, the block must be designed to be rapidly driven from an open to a closed position by
the detonation pressures in the chamber. While this type of block will provide some protection
of chamber contents from an explosion in another chamber, blast doors must also be used to
provide complete protection. Tests have shown that a closure block, with sufficient mass, can
obstruct the initial outflow of airblast from an explosion in a chamber to reduce pressures in the
connecting tunnels by a factor of two or more, even when the block is destroyed. Blocks with
sufficient strength to remain structurally intact can provide greater reductions. Because many
variables influence the performance of a closing device, their design details must be developed
on a site-specific basis.

C5.2.3.3.5.1.1. For loading densities (w) of 0.625 lb/ft3 [10 kg/m3] or higher,
a 50 percent reduction in IBD may be applied to the use of a high pressure closure block
provided it is designed to remain intact in the event of an explosion.

C5.2.3.3.5.1.2. For lower loading densities, use the following reductions:

C5.2.3.3.5.1.2.1. 0.0625 < w < 0.625 lb/ft3 [1.0 < w < 10 kg/m3],
reductions may be calculated by:
y(%) = 50log10(16.02w) [English EQN C5.2-1]
[y(%) = 50log10 (1.0w)] [Metric EQN C5.2-2]
where y is the percent reduction in IBD, and w is loading density in lb/ft3 [kg/m3]

C5.2.3.3.5.1.2.2. For w < 0.0625 lb/ft3 [w <1 kg/m3]:

55 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

y(%) = 0.

C5.2.3.3.6. When used to protect the contents of a chamber from an explosion in

another chamber, the block must be designed to move from a normally closed position to an
open position when entry is required. Blast doors are not required for this type of closure block.

C5.2.3.4. Chamber Separation Requirements. Minimum storage chamber separation

distances are required to prevent or control the communication of explosions or fires between
chambers. There are three modes by which an explosion or fire can be communicated: rock
spall, propagation through cracks or fissures, and airblast or thermal effects traveling through
connecting passages. Spalled rock of sufficient mass that is traveling at a sufficient velocity may
damage or sympathetically detonate impacted AE in the acceptor chambers.

C5.2.3.4.1. Prevention of Damage by Rock Spall (HD 1.1 and HD 1.3). The
chamber separation distance is the shortest distance (rock thickness) between two chambers.
When an explosion occurs in a donor chamber (a PES), a shock wave is transmitted through the
surrounding rock. The intensity of the shock decreases with distance. For small chamber
separation distances, the shock may be strong enough to produce spalling of the rock walls of
adjacent ES chambers. When no specific protective construction is used:

C5.2.3.4.1.1. For moderate to strong rock, with loading densities less than or
equal to 3.0 lb/ft3 [48.1 kg/m3], the minimum chamber separation distance (Dcd) required to
prevent hazardous spall effects is:
Dcd = 2.5W1/3 [English EQN C5.2-3]
[Dcd = .99Q1/3] [Metric EQN C5.2-4]
where Dcd is in ft and W is in lbs [Dcd is in m, and Q is in kg]. (NOTE: Dcd shall not be less than
15 ft [4.6 m].)

C5.2.3.4.1.1.1. For loading densities greater than 3.0 lbs/ft3 [48kg/m3], the
separation distance is:
Dcd = 5.0W1/3 [English EQN C5.2-5]
[Dcd = 1.98Q1/3] [Metric EQN C5.2-6]

C5.2.3.4.1.2. For weak rock, at all loading densities, the separation distance
is:
Dcd = 3.5W1/3 [English EQN C5.2-7]
[Dcd = 1.39Q1/3] [Metric EQN C5.2-8]

C5.2.3.4.1.3. The equations above are the basis for values of Dcd listed in Table
C5.T2.).

C5.2.3.5. Prevention of Propagation by Rock Spall (HD 1.1 and HD 1.3). Because rock
spall is considered an immediate mode of propagation, time separations between donor and
acceptor explosions may not be sufficient to prevent coalescence of blast waves. If damage to
AE stored in adjacent chambers is acceptable, chamber separation distances from those
determined to prevent damage (see subparagraph C5.2.3.2.1.) can be reduced to prevent

56 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

propagation by rock spall. To prevent propagation, the separation distances between donor and
acceptor chambers are calculated using the below equations. If the required separation distances
defined below cannot be met, explosives weights in all chambers must be added together to
determine W, unless analyses or experiments demonstrate otherwise.

C5.2.3.5.1. When no special protective construction is used, the separation distance

(Dcp) to prevent propagation by rock spall is:
Dcp = 1.5W1/3 [English EQN C5.2-9]
1/3
[Dcp = 0.59Q ] [Metric EQN C5.2-10]
where Dcp is in ft and W is in lbs. [Dcp is in m and Q is in kg]

C5.2.3.5.2. When the acceptor chamber has protective construction to prevent spall
and collapse, the Dcp to prevent propagation by impact of rock spall is:
Dcp = 0.75W1/3 [English EQN C5.2-11]
1/3
[Dcp = 0.30Q ] [Metric EQN C5.2-12]
where Dcp is in ft and W is in lbs. [Dcp is in m and Q in kg]

C5.2.3.5.3. Separation distances, Dcp and Dcd, are listed in Table C5.T2. These
distances are based on an explosive loading density of 17 lb/ft3 [272.3 kg/m3] and will likely be
safety conservative for lower loading densities.

C5.2.3.6. Prevention of Propagation Through Cracks and Fissures (HD 1.1 and HD 1.3).
Propagation between a donor and an acceptor chamber has been observed to occur when natural,
near-horizontal jointing planes, cracks, or fissures in the rock between the chambers are opened
by the lifting force of the detonation pressure. Prior to construction of a multi-chamber
magazine, a careful site investigation must be made to ensure that such joints or fissures do not
extend from one chamber location to an adjacent one. Should such defects be encountered
during facility excavation, a reevaluation of the intended siting is required.

C5.2.3.7. Prevention of Propagation through Passageways (HD 1.1 and HD 1.3). Flame
and hot gas may provide a delayed mode of propagation. Time separations between the events in
the donor chamber and the acceptor chamber by this mode will likely be sufficient to prevent
coalescence of blast waves. Consequently, siting is based on each chamber’s NEWQD. To
protect assets, blast and fire resistant doors may be installed within multi-chambered facilities.
Evaluations for required chamber separations due to this propagation mode should be made on a
site-specific basis using procedures outlined in CoE definitive drawing DEF 421-80-04. For HD
1.1 and HD 1.3 materials:

C5.2.3.7.1. Chamber entrances at the ground surface, or entrances to branch tunnels

off the same side of a main passageway, shall be separated by at least 15 ft [4.6 m].

C5.2.3.7.2. Entrances to branch tunnels off opposite sides of a main passageway shall
be separated by at least twice the width of the main passageway.

C5.2.3.8. Chamber Cover Thickness. The chamber cover thickness is the shortest
distance between the ground surface and the natural rock surface at the chamber’s ceiling or, in

57 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

some cases, a chamber’s wall. For all types of rock, the critical cover thickness required to
prevent breaching of the chamber cover by a detonation (Cc) is
Cc = 2.5W1/3 [English EQN C5.2-13]
1/3
[Cc = .99Q ] [Metric EQN C5.2-14]
where Cc is in ft and W is in lbs [Cc is in m and Q is in kg].

C5.2.4. HPM. HPM allow a reduction in encumbered land by limiting the MCE to a
quantity considerably less than that stored in the HPM. (NOTE: HPM are to be constructed per
NAVFAC guidance, as outlined in Table AP1-1. of Reference (j), and are to be sited at the IMD
provided by Table C9.T6.). HPM separation walls protect against fire propagation between
internal storage areas. Although IMD provides nearly complete asset protection between HPM
(MCE = 60,000 lbs [27,216 kg] maximum), AE damage may occur to about K9 [3.57] from a
donor NEW > 350,000 lbs [158,757 kg].

C5.2.5. AGM. There are no DDESB construction criteria for AGM. However, such
structures must meet the criteria of Chapters 6 and 7.

59 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.6. Special Structures. The DDESB has approved reduced QD for structures and
containers listed in Table AP1-4. of Reference (j).

C5.3. BARRICADES

C5.3.1. General

C5.3.1.1. Properly constructed and sited barricades and undisturbed natural earth have
explosives safety applications for both protecting against low-angle fragments and reducing
shock overpressure loads very near the barricade. Barricades provide no protection against high-
angle fragments or lobbed AE. If the barricade is destroyed in the process of providing
protection, then secondary fragments from the destroyed barricade must also be considered as
part of a hazards analysis.

C5.3.1.2. To reduce hazards from high-velocity, low-angle fragments, the barricade must
be placed between the PES and the ES so that the fragments of concern impact the barricade
before the ES. The barricade must both be thick enough so that it reduces fragment velocities to
acceptable levels and high enough so that it intercepts the ballistic trajectories of the fragments
of concern.

C5.3.1.3. A barricade placed between a PES and an ES interrupts the direct line-of-sight
motion of the shock wave. If the barricade has sufficient dimensions and is located close enough
to the ES, significant reductions in shock loading to selected areas of the ES may be realized.

C5.3.2. Barricade Designs

C5.3.2.1. Chapter 6 of Reference (j) lists DDESB-approved designs and construction

materials for barricades. Use of these barricades satisfies barricading criteria.

C5.3.2.2. Alternate barricade designs (e.g., earth-filled steel bin) may be approved by the
DDESB, provided that testing or analysis demonstrates their effectiveness in stopping high-
velocity, low-angle fragments.

C5.3.2.3. Barricade Size and Orientation for Protection Against High-Speed, Low-Angle
Fragments. The location, height, and length of a barricade shall be determined as follows:

C5.3.2.3.1. Location. The barricade may be placed anywhere between the PES and
the ES. The location shall determine the barricade’s required height and length.

C5.3.2.3.2. Height. To determine the required barricade height:

C5.3.2.3.2.1. Establish a reference point at the top of the far edge of one of the
two AE stacks between which the barricade is to be constructed. When both stacks are of equal
height, the reference point may be established on either stack. If the tops of the two stacks are
not of equal height (elevation), the reference point shall be on the top of the lower stack. To

60 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

preclude building excessively high barricades, the barricade should be located as close as
possible to the stack on which the reference point was established. (See Figure C5.F3.)

C5.3.2.3.2.2. Draw a line from the reference point to the highest point of the
other stack.

C5.3.2.3.2.3. Draw a second line from the reference point forming an angle of
two degrees above the line.

C5.3.2.3.3. Length. The barricade’s length shall be determined per Figure C5.F3.

C5.3.2.4. Barricade Size and Orientation for Protection Against Overpressure. General
procedures to predict pressure mitigation versus barricade design and location have not been
developed. However, based on direct-experimental work, the overpressure loading on a surface
area shielded by a barricade is reduced by approximately 50 percent when the following
conditions are met:

C5.3.2.4.1. Location. The barricade’s standoff is within two barricade heights of the
protected area.

C5.3.2.4.2. Height. The top of the barricade is at least as high as the top of the
protected area.

C5.3.2.4.3. Length. The length of the barricade is at least two times the length of the
protected area.

C5.3.3. Barricade Construction Materials

C5.3.3.1. Materials for earthen barricades shall be reasonably cohesive and free from
harmful (toxic) matter, trash, debris, and stones heavier than ten pounds [4.54 kg] or larger than
six inches [152 mm] in diameter. The larger of acceptable stones shall be limited to the lower
center of fills. Earthen material shall be compacted and prepared, as necessary, for structural
integrity and erosion control. Solid or wet clay or similar types of soil shall not be used in
barricades because they are too cohesive. If it is impossible to use a cohesive material (e.g., in
sandy soil) the barricade shall be finished with a suitable material (e.g., geotextiles, gunnite) that
shall not produce hazardous debris, but shall ensure structural integrity.

C5.3.3.2. The slope of an earthen barricade must be two horizontal to one vertical, unless
erosion controls are used. Earthen barricades with slopes no greater than one and one half
horizontal to one vertical that were approved prior to 1976 may continue to be used. However,
renovations to these facilities shall meet the above criteria, when feasible.

C5.3.4. Portal Barricades for Underground Storage Facilities. Portal barricades allow
reduction in IBD for underground magazines. Criteria for the location and construction of portal
barricades are illustrated in Figure C5.F4. and include:

C5.3.4.1. Location. Portal (entry or exit) barricades shall be located immediately in front
of an outside entrance or exit to a tunnel leading to an explosives storage point. The portal
barricade should be centered on the extended axis of the tunnel that passes through the portal and
shall be located a distance of not less than one and not more than three tunnel widths from the
portal. The actual distance should be no greater than that required (based on the turning radius
and operating width) to allow passage of any vehicles or materials handling equipment that may
need to enter the tunnel.

C5.3.4.2. Height. The height of the barricade, along its entire width, shall be sufficient
to intercept an angle of 10 degrees above the extended height of the tunnel.

C5.3.4.3. Width and Length

C5.3.4.3.1. The width of the central face typically equals the width of the tunnel at
the portal.

C5.3.4.3.2. The front face (i.e., the face toward the entry or exit) shall be vertical and
concave in plan view, consisting of a central face oriented perpendicular to the tunnel axis, and
wing walls.

C5.3.4.3.3. The wing walls shall be of sufficient width so that the entire barricade
length intercepts an angle of 10 degrees (minimum) to the right and left of the extended tunnel
width.

C5.3.4.4. Construction. To withstand the impact of debris ejected from the tunnel, the
front face (including wing walls) shall be constructed of reinforced concrete, with a minimum
thickness equal to 10 percent of the barricade height, but in no case less than 12 inches [30.5
cm]. The concrete wall shall have a spread footing of sufficient width to prevent significant
settlement. In addition, the central wall, wing walls, and footing shall be structurally tied
together to provide stability. The backfill behind the concrete wall may be composed of any fill
material, to include rock rubble from the tunnel excavation, with a maximum particle size of 6
inches [15.2 cm] within the area extending out to 3 feet [0.9 m] from the rear face of the wall.

C5.3.5. Earth-Filled, Steel Bin-Type Barricades (ARMCO Revetments or Equivalent) for

Outside Storage

C5.3.5.1. These barricades, also known as ARMCO, Inc. revetments, are earth-filled
steel bins used to separate AE awaiting scheduled processing (e.g., AE on a flight line associated
with aircraft parking or loading operations; or the temporary positioning of AE awaiting transfer
to preferred, long-term storage). These barricades, which are also used to separate explosive-
loaded aircraft, are normally used to form a series of cells. They are designed to limit the MCE,
for QD siting purposes, of AE properly positioned in separate cells by preventing prompt
detonation transfer to adjacent cells.

DoD 6055.09-STD, February 29, 2008

C5.3.5.2. ARMCO, Inc. Revetment Cells (see paragraph C6.2.3. of Reference (j)):

C5.3.5.2.1. ARMCO, Inc. revetments cells are approved for storage of any HD 1.1
and HD 1.2 AE assigned to SG 1 through 4, as discussed in paragraph C3.2.3. In addition,
storage of HD 1.3, HD 1.4, or HD 1.6 items is approved.

C5.3.5.2.2. When properly sited, these cells prevent prompt detonation transfer;
however, all assets in the series of cells are at risk of loss. Although a revetment is effective in
limiting the blast loading of an adjacent ES to that produced by the largest contents of a single
cell, there is a significant probability that the contents of many of the cells will be damaged or
destroyed by the initial and subsequent fire and explosion events. The extent of such losses
increases with the amount of explosives present.

C5.3.5.3. Types of ARMCO, Inc. Revetments

C5.3.5.3.1. Type A revetments, which must be a minimum of 7 feet [2.1 m]

thick, can be used to limit a MCE in a series of cells to the largest quantity in a single
cell, provided the quantity in the single cell does not exceed 30,000 pounds NEW [NEQ]
[13,608 kg].

C5.3.5.3.2. Type B revetments, which must be a minimum of 5.25 feet [1.6 m] thick,
can be similarly used to limit the MCE, provided no cell contains more than 5,000 pounds NEW
[2,268 kg NEQ].

C5.3.5.4. For ARMCO, Inc. revetments to be used effectively, the following conditions
must be met:

C5.3.5.4.1. The criteria shown in Figure C5.F3.

C5.3.5.4.2. AE shall be positioned no closer than 10 feet [3.1 m] from cell walls, no
closer than 3 feet [0.9 m] from the end of the wing walls, and no higher than 2 feet [0.6 m] below
the top of cell walls.

C5.3.5.4.3. AE shall be distributed over the available area within the cell, rather than
being concentrated in a small area.

C5.3.5.4.4. AE stored in a cell in quantities near the maximum NEW limit shall not
be configured into a single row of pallets, stacks, or trailers.

C5.3.5.4.5. The storage of AE in flammable outer-pack configurations shall be

minimized.

stringent explosives safety criteria. (For example, an airfield restricted to DoD use only,
changed to joint DoD and non-DoD use.)

C5.4.2. Vulnerable facility construction. Although site plans for construction of vulnerable
facilities (e.g., schools, high-rise buildings, restaurants) located on a DoD installation that are
outside but near QD arcs are not required, it is recommended that they be submitted to the
DDESB for review and comment.

C5.4.3. Site and general construction plans need not be submitted to the DDESB for facility
modifications, change of mission, or change of operations that do not introduce additional
explosives hazards or do not increase NEW, chemical agent hazards, or personnel exposure.

69 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C6. CHAPTER 6
ELECTRICAL STANDARDS

C6.1. GENERAL

This chapter establishes safety standards for the design and installation of electrical equipment
and wiring for explosives environments.

C6.1.1. For this purpose, the Department of Defense adopts Article 500 of the Code
“Hazardous (Classified) Locations” of the National Fire Protection Association (NFPA) 70
(Reference (l)) (a.k.a., National Electrical Code (NEC)). This Code establishes standards for the
design and installation of electrical equipment and wiring for atmospheres containing
combustible dusts, flammable vapors or gasses that are comparably hazardous.

C6.1.2. This chapter does not address extraordinarily hazardous situations (e.g.,
nitroglycerin manufacturing) that will require special consideration and design features. In these
situations, the DoD Components shall develop site-specific design criteria.

C6.2. HAZARDOUS LOCATIONS

NEC definitions of Class I, Division 1 and Class II, Division 1 hazardous locations are modified
as follows for DoD explosives applications:

C6.2.1. Areas containing explosives dusts or explosives that may through handling produce
dust capable of being dispersed in the atmosphere shall be regarded as Class II, Division 1.

C6.2.2. Areas in which explosives sublimation or condensation may occur shall be regarded
as both Class I, Division 1 and Class II, Division 1.

C6.3. SPECIAL OCCUPANCIES

To ensure assignment to the proper hazardous location, class, and group, it is necessary to have
knowledge of the properties of explosives involved. Minimum requirements include sensitivity
to heat and spark and thermal stability.

C6.3.1. If the properties of an explosive are such that Class I or Class II, or both, provide
inadequate protection under prevailing conditions, use of any of the following approaches is
acceptable:

C6.3.1.1. Intrinsically safe equipment.

C6.3.1.2. Purged or pressurized and suitably temperature-limited equipment.

70 CHAPTER 6
DoD 6055.09-STD, February 29, 2008

C6.3.1.3. Exclusion of electrical equipment from the hazardous atmosphere.

C6.3.1.4. Isolation of equipment from the hazardous atmosphere by means of dust, vapor,
or gas-free enclosures with surface temperatures positively maintained at safe levels.

C6.3.2. Underground Storage Facilities. All wiring and electrical equipment in underground
storage facilities shall, in addition to any other requirements of this chapter, be of moisture and
corrosion-resistant materials and construction unless a site-specific analysis indicates that such
construction is not necessary. Underground facilities shall have emergency lighting systems to
provide minimum illumination in the event of a power failure.

C6.4. STATIC ELECTRICITY

Personnel and equipment in hazardous locations (section C6.2.) and locations where static
sensitive Electro-Explosive Device (EED) are exposed shall be grounded in a manner that
effectively discharges static electricity and prevents static electricity accumulations that may be
capable of initiating dusts, gases, vapors, or exposed EED. Permanent equipment in contact with
conductive floors and tabletops shall not be considered grounded. Static grounds shall be
bonded to the facility’s grounding system. (See Chapter 7.)

C6.5. ELECTRIC SUPPLY SYSTEMS

There may be mutual hazards when PES are located near electric supply lines. To protect
against these hazards, the following separation requirements apply to all new construction
(PTRD and IBD specified in paragraphs C6.5.3. and C6.5.4. are based on airblast overpressure
only; fragment distances do not apply):

C6.5.1. Electric lines serving explosives operating facilities shall be installed underground
from a point not less than 50 ft [15.3 m] away from such facilities.

C6.5.2. Overhead electric service lines shall be no closer to combustible PES or to an open
PES than the length of the electric lines between the nearest service poles and the length of the
nearest service pole. An exception is when an effective means (e.g., line spacers, weights) is
provided to ensure that energized lines on breaking cannot come into contact with the facility or
its appurtenances.

C6.5.3. Electric distribution lines carrying less than 69 kilovolt (kV), the tower or poles
supporting those lines, and unmanned electrical substations shall be no closer to PES than PTRD.
(Lesser distance permitted by section C9.4. for the placement of electrical substations and
transformers that support explosives areas.)

C6.5.4. Electric transmission lines carrying 69 kV or more and the tower or poles supporting
them shall be located no closer to the PES than:

71 CHAPTER 6
DoD 6055.09-STD, February 29, 2008

C6.5.4.1. IBD, if the line in question is part of a grid system serving a large off-base
area.

C6.5.4.2. PTRD, if loss of the line does not create serious social or economic hardships.

C6.5.5. Electric transmission lines that can be interrupted without loss of power (i.e., power
is rerouted through existing lines or networks) shall be separated from explosives sites in
accordance with paragraph C6.5.2.

C6.6. HAZARDS OF ELECTROMAGNETIC RADIATION TO ORDNANCE (HERO)

Military Munitions (at times also referred to as ordnance or AE) containing Electrically Initiated
Devices (EID) shall be designed or protected such that Electromagnetic Radiation (EMR) does
not cause their inadvertent initiation, degradation, or disablement. Both direct Radio Frequency-
(RF) induced actuation of the EID or electrical coupling to and triggering of the associated firing
circuits can occur, especially in a tactical radiated Electromagnetic Environment (EME).
Examples of EID include the following: exploding foil initiators, laser initiators, burn wires,
fusible links, and EED, such as hot bridge wires, carbon bridges, and conductive compositions.

C6.6.1. During acquisition, HERO testing and certification shall be accomplished, both for
routine employment mission profiles, and for any anticipated joint- or combined-operational
employment to include transshipment exposures through EME differing from the employment
environment.

C6.6.2. During subsequent phases of life cycle munitions management, additional HERO
testing and certification shall be accomplished when legacy munitions are redesigned or before
any employment through EME for which they where not previously HERO certified.

C6.6.3. Minimally, HERO certification shall involve exposure without adverse effects of the
munitions to the EME relevant to all life cycle configurations, including packaging, handling,
storage, transportation, checkout, loading and unloading, and launch.

C6.6.4. All HERO test and certification data shall be compiled in a centralized data
repository to support the Joint Spectrum Center Ordnance Electromagnetic Environmental
Effects (E3) Risk Assessment Database (JOERAD), for subsequent use in information
applications supporting Combatant Commands and the DoD Components.

C6.6.5. The DoD Components shall take measures (e.g., identifying susceptibilities,
quantifying electromagnetic environments, evaluating risks associated with operating
procedures, and establishing tailored Emission Control (EMCON) instructions) to ensure that
HERO effects on munitions are resolved during the planning of joint or combined operations or
training exercises.

72 CHAPTER 6
DoD 6055.09-STD, February 29, 2008

C7. CHAPTER 7
LIGHTNING PROTECTION

C7.1. POLICY

This chapter defines minimum explosives safety criteria for the design, maintenance, testing, and
inspection of Lightning Protection Systems (LPS). Properly maintained LPS are required (with
exceptions) for AE facilities. If other LPS for these facilities are used, they shall offer equivalent
protection to the types prescribed herein.

C7.2. LPS DESIGN

C7.2.1. Design and installation of an LPS used to protect DoD AE must meet, at a minimum,
the requirements of NFPA 780 Lightning Protection Code (Reference (m)). LPS must feature air
terminals, low impedance paths to ground, sideflash protection, surge suppression or grounding
of all conductive penetrations into the protected area, and earth electrode systems. Structural
elements of the building may serve as air terminals, down conductors, or the earth electrode.
LPS used to protect DoD AE must be designed to intercept lightning at a 100 ft [30.5 m] or less
striking distance arc in accordance with Reference (m).

C7.2.1.1. Air Terminals. An air terminal is a component of an LPS that is able to safely
intercept lightning strikes. Air terminals may include overhead wires or grids, vertical spikes, or
a building’s grounded structural elements. Air terminals must be capable of safely conducting a
lighting strike.

C7.2.1.2. Down Conductors. Down conductors (flat or round) provide low impedance
paths from the air terminals to the earth electrode (ground) system. Structural elements having a
high-current capacity and a low impedance to ground need not be augmented with wires. Where
wires are used as down conductors, these shall meet the requirements of Reference (m).

C7.2.1.3. Sideflash Protection. Protection from sideflash caused by lightning shall be

obtained by either separation distance or bonding in accordance with Reference (m), except as
modified herein.

C7.2.1.3.1. Fences and railroad tracks located within six feet of a structure’s LPS
shall be bonded to the structure’s LPS.

C7.2.1.3.2. The reinforcing bars in adjacent structural elements must be joined in a

manner to provide electrical bonding between the elements. This is an absolute requirement for
facilities that are used to store AE. Techniques commonly used and approved in the construction
industry to join reinforcing steel are acceptable for this purpose. The steel arch of an ECM must
be similarly joined to the rebar in the floor.

73 CHAPTER 7
DoD 6055.09-STD, February 29, 2008

C7.2.1.4. Surge Protection for Incoming Conductors. An LPS shall include surge
protection for all incoming conductors. The surge protection must include suppression at the
entrance to the building from each wire to ground. Shielded cabling, power cabling,
communication lines, and electrical conduit shall be buried underground in conduit for a
minimum of 50 feet [15.3 m] before entering the structure. All other metallic utility lines and
pipes must be electrically connected to the LPS or the structural steel of the building just before
they enter the building.

C7.2.1.5. Earth Electrode System. Earth electrode systems dissipate the current from a
lightning strike to ground. Earth electrode systems may be Ufer grounds, ground loop
conductors, radials, grounding rods, ground plates, a cable immersed in nearby salt water,
chemical grounds that are installed for the purpose of providing electrical contact with the earth,
or combinations of these.

C7.2.2. Underground Storage Facility.

An underground storage site normally requires designed protection against lightning only for
exposed or partially exposed parts. Metal and structural parts of the site that have less than 2 feet
[60 cm] of earth cover shall be protected as for an aboveground site. Lightning protection
requirements shall be considered on a site-specific basis.

C7.3. INSPECTION, TESTING, AND TRAINING

C7.3.1. Visual inspection. LPS shall be periodically inspected at a frequency determined by

each DoD Component. Visual inspections shall be conducted at least yearly.

C7.3.2. Electrical tests. LPS shall be periodically tested electrically as specified in

subparagraphs C7.3.2.1. and C7.3.2.2. Electrical testing shall be accomplished at least every 2
years.

C7.3.2.1. Bonding (Resistance) Tests. Bonding (resistance) tests shall be conducted

periodically (or after facility modification that may affect bonding). A maximum resistance
value of one ohm is permitted across all bonds.

C7.3.2.2. Resistance to Earth Tests. Resistance to earth tests of LPS shall be conducted
periodically during the same season of the year (or after facility modification that may have
affected the system).

C7.3.3. Records. Records of resistance to earth tests shall be kept on file for the last six
inspection cycles. These records shall be reviewed for trend analysis.

C7.3.4. Training. Personnel responsible for maintenance, inspection, and testing must be
familiar with the fundamentals described in Reference (m) and herein as they relate to AE
facilities to ensure requirements of paragraphs C7.3.1. and C7.3.2. are met.

74 CHAPTER 7
DoD 6055.09-STD, February 29, 2008

C7.4. LIGHTNING PROTECTION EXCEPTIONS

Properly maintained LPS are required for AE facilities, with the follow exceptions:

C7.4.1. Explosives operations served by a local lightning warning system that permit
operations to be terminated before the incidence of an electrical storm, if all personnel are
provided with protection equivalent to PTRD, and the damage from a lighting strike is
acceptable to the DoD Component.

C7.4.2. Facilities containing only AE that cannot be initiated by lightning, as determined by

the DoD Component concerned and approved by DDESB, and where no fire hazard exists.

C7.4.3. Facilities where personnel are not expected to sustain injury and at the same time,
the resulting economic loss of the structure, its contents, and/or surrounding facilities is minimal.

75 CHAPTER 7
DoD 6055.09-STD, February 29, 2008

C8. CHAPTER 8
HAZARD IDENTIFICATION FOR FIREFIGHTING
AND EMERGENCY PLANNING

C8.1. SCOPE AND APPLICABILITY

C8.1.1. This chapter establishes standard firefighting hazard identification measures to

ensure a minimum practicable risk in fighting fires involving AE. These identification measures
are based on the classification of AE fires into four fire divisions according to their predominant
hazard. Guidelines are provided to DoD Components for the development of emergency plans,
which include safety, security, and environmental protection. These plans shall be coordinated
with local authorities.

C8.1.2. The following are outside the scope of this chapter and are the responsibility of the
DoD Component:

C8.1.2.1. Firefighting procedures.

C8.1.2.2. Training of firefighting personnel.

C8.1.2.3. Use and maintenance of firefighting equipment and vehicles.

C8.1.2.4. Provision of water supply and alarm systems.

C8.1.2.5. First aid measures.

C8.1.2.6. Other measures required in firefighting.

C8.1.3. AE hazard symbols and supplemental symbols including chemical agent symbols
(see section C8.4.) are for firefighting situations.

C8.2. FIRE DIVISIONS

There are four fire divisions. Fire division 1 indicates the greatest hazard. The hazard decreases
with ascending fire division numbers from 1 to 4 and is related to HD as shown in Table C8.T1.

Table C8.T1. Fire Divisions

Fire Division Predominant Hazard HD

1 Mass explosion 1.1 and 1.5
2 Non-mass explosion, fragment producing 1.2 and 1.6
3 Mass fire, minor blast or fragment 1.3
4 Moderate fire, no blast or fragment 1.4

76 CHAPTER 8
DoD 6055.09-STD, February 29, 2008

C8.3. FIRE DIVISION SYMBOLS

C8.3.1. The four fire divisions are represented by four distinctive symbols so that
firefighting personnel can recognize the hazards. A fire division number is shown on each
symbol. For the purpose of identifying these symbols from long range, the symbols differ in
shape as shown in Table C8.T2.

Table C8.T2. Fire Division Symbols

Shape Fire Division Symbol

Octagon 1
Cross 2
Inverted triangle 3
Diamond 4

C8.3.2. The shape and dimensions of the symbols are shown in Figure C8.F1. This shape
and color scheme is consistent with UN, North Atlantic Treaty Organization (NATO), and
International Maritime Organization (IMO) requirements. For application on doors or lockers
inside buildings, half-sized symbols may be used.

C8.3.3. At the discretion of the DoD Components, circumstances (e.g., security) may make
it undesirable to post fire symbols at an AE storage site.

C8.4. CHEMICAL AGENT AND CHEMICAL MUNITION HAZARD SYMBOLS

C8.4.1. The storage of chemical agents and chemical munitions requires the use of chemical
hazard symbols. These symbols (see Figures C8.F2. and C8.F3.) shall be used in conjunction
with fire symbols, where appropriate. Some of the common chemical agents used in AE, the CG
of that AE, and the chemical hazard symbols required in storage are specified in Table C8.T3.

C8.4.2. The following sections describe these symbols, the hazards indicated by the
symbols, and the recommended protective clothing and equipment to be used for fighting fires
involving these chemical agents and chemical munitions. The DoD Components shall determine
protective clothing requirements for other than firefighting situations.

C8.4.2.3. Set 3 of Chemical Hazard Symbol 1 requires full protective clothing (see
Figure C8.F2. and Table C8.T3.) and indicates the presence of WP or other spontaneously
combustible material. The following protective clothing shall be used:

C8.4.2.3.1. Service-certified protective gas masks or SCBA.

C8.4.2.3.2. Flame-resistant coveralls.

C8.4.2.3.3. Flame-resistant gloves.

C8.4.2.3.4. Firefighting personnel equipped with normal heat-resistant clothing (e.g.,

bunker suit) and gas mask or SCBA do not require the set 3 protective clothing.

C8.4.2.4. Chemical hazard symbol 2 requires the wearing of breathing apparatus (see
Figure C8.F2. and Table C8.T3.) and indicates the presence of incendiary or readily flammable
chemical agents that present an intense radiant heat hazard. Protective masks shall be used to
prevent inhalation of smoke from burning incendiary mixtures.

C8.4.2.5. Chemical hazard symbol 3 warns against applying water (see Figure C8.F2.
and Table C8.T3.) and indicates a dangerous reaction will occur if water is used in an attempt to
extinguish fire.

C8.5. FIREFIGHTING MEASURES

C8.5.1. Firefighters should have a thorough knowledge of the hazards associated with AE
fires and expected AE reactions. The DoD Component shall brief the firefighting forces and
other essential personnel before approaching the scene of the fire. They shall be informed of the
known hazards and conditions existing at the fire scene prior to proceeding to the fire location.

C8.5.2. Fires involving AE will be fought according to the HD, fire division, the progression
of the fire, and the procedures specified by the DoD Component. Special firefighting

82 CHAPTER 8
DoD 6055.09-STD, February 29, 2008

instructions addressing AE hazards will be developed according to the needs of the DoD
Component.

C8.5.3. All fires in the vicinity of AE shall be immediately reported and:

C8.5.3.1. Shall be fought if not involving AE.

C8.5.3.2. Shall not be fought if the fire involves AE, or is supplying heat to the AE, or is
so large that it cannot be extinguished with the equipment at hand. Personnel shall be evacuated
per paragraph C8.5.4.

C8.5.4. Emergency Withdrawal Distances. Commanders are responsible for developing

evacuation plans that include the applicable withdrawal distances as part of the installation’s
emergency planning (see section C8.6.).

C8.5.4.1. Nonessential Personnel. These emergency withdrawal distances are intended

for application in emergency situations only and are not used for facility siting.

C8.5.4.1.1. The initial withdrawal distance for nonessential personnel shall be at least
IBD for the PES involved. If the fire involves AE, AE involvement is imminent, or the fire is or
may become uncontrollable, then use the emergency withdrawal distances listed in Table C8.T4.
The emergency withdrawal distances depend on fire involvement and on whether or not the HD,
fire division and quantity of explosives are known. If fire is not affecting AE or involvement is
not imminent, then emergency authorities shall determine the withdrawal distance based on the
situation at hand.

C8.5.4.1.2. Structures or protected locations offering equivalent protection for the

distances in Table C8.T4. may be used in lieu of relocating personnel from the structure or
location to the specified emergency withdrawal distance.

C8.5.4.2. Essential Personnel. Emergency authorities on site shall determine the

withdrawal distance for essential personnel at accidents. Emergency authorities shall determine
the essential personnel.

C8.5.5. AE containing both explosives and chemical agents (see Table C8.T3.) requires
special attention and precautions in firefighting. Fires involving such AE shall be fought in
accordance with their fire division characteristics. Responding personnel must consider the
additional hazards and precautions discussed in Chapter 11 for the chemical agents involved.

C8.5.6. Entry to underground storage facilities following a fire or explosion requires special
precautions. Emergency personnel shall monitor for the presence of toxic fumes or oxygen-
depleted atmospheres and evaluate structural damage during initial entry following an accident.
Commanders shall develop written procedures that define actions to be taken in such emergency
situations.

83 CHAPTER 8
DoD 6055.09-STD, February 29, 2008

C8.6. EMERGENCY PLANNING

C8.6.1. Installations or responsible activities shall develop Standard Operating Procedures

(SOP) or plans designed to provide safety, security, and environmental protection for accidents
involving AE. Plans shall be coordinated with the applicable Federal, State, and local
emergency response authorities (e.g., law enforcement, fire departments, and hospitals) and any
established Local Emergency Planning Committees (LEPC). The SOP or plans shall include the
following:

C8.6.1.1. Specific sections and guidance that address emergency preparedness,

contingency planning, and security. (For security, the SOP or plans shall limit access to accident
sites to trained and authorized personnel.)

C8.6.1.2. Procedures that minimize the possibility of an unpermitted or uncontrolled

detonation, release, discharge, or migration of AE out of any storage unit when such release,
discharge, or migration may endanger human health or the environment.

C9. CHAPTER 9
QUANTITY-DISTANCE AND SITING

C9.1. GENERAL

The damage or injury potential of explosions is normally determined by the separation distance
between PES and ES; the ability of the PES to suppress blast overpressure, primary and
secondary fragments; and the ability of the ES to resist explosion effects. This chapter:

C9.1.1. Defines permissible exposures for both accidental and intentional detonations.

C9.1.2. Sets minimum standards for separation distances between PES and ES by taking into
account anticipated explosion effects, suppression, and resistance.

C9.1.3. Establishes explosives safety siting criteria (QD relationships) for PES and ES,
based on blast, fragment, firebrand, thermal, and groundshock effects. QD is determined by the
effect requiring the greatest distance.

C9.2. DETERMINING THE QUANTITY OF EXPLOSIVES

C9.2.1. General. The NEWQD in an AE facility is calculated as shown below. If DDESB-

approved buffer configurations are provided, the NEWQD is the explosives weight of the largest
stack plus the explosives weight of the buffer material, excluding the NEW of HD 1.4. Where
the DDESB has approved an HE equivalence for a propellant or pyrotechnic, then this HE
equivalence may be used in determining NEWQD. (The JHCS provides explosives weights for
all DoD Hazard Classified AE.)

C9.2.1.1. Mass-explosion (HD 1.1). The NEWQD is the total High Explosive Weight
(HEW) and the total Net Propellant Weight (NPW). For HD 1.1, NEWQD equals the NEW.

C9.2.1.2. Non-mass Explosion, Fragment Producing (HD 1.2).

C9.2.1.2.1. HD 1.2.1. The NEWQD is the HEW plus the NPW in all HD 1.2.1
items. In certain situations, the MCE, as outlined in subparagraph C9.4.2.5., shall be used as the
basis for determining applicable QD.

C9.2.1.2.2. HD 1.2.2. The NEWQD is the HEW plus the NPW in all HD 1.2.2
items.

C9.2.1.2.3. HD 1.2.3. The NEWQD is the HEW plus the NPW in all HD 1.2.3
items. This material is treated as HD 1.3, however, a minimum IBD shall apply, as outlined in
subparagraph C9.4.2.12.

88 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.2.1.3. Mass Fire, Minor Blast, or Fragment (HD 1.3). The NEWQD is the HEW plus
the NPW plus the total weight of pyrotechnics in all HD 1.3 items.

C9.2.1.4. Moderate Fire, No Blast, or Fragment (HD 1.4). The NEWQD is the HEW
plus the NPW plus the total weight of pyrotechnics in all HD 1.4 items.

C9.2.1.5. Explosive Substance, Very Insensitive (With Mass Explosion Hazard) (HD
1.5). The NEWQD is the HEW plus the NPW in all HD 1.5 items. For HD 1.5, NEWQD equals
the NEW.

C9.2.1.6. Explosive Article, Extremely Insensitive (HD 1.6). The NEWQD is the total
weight of EIDS in all HD 1.6 items. However, the weight of EIDS in a single HD 1.6 item shall
also be considered, as specified in Table C9.T15., for determining QD.

C9.2.1.7. Exclusions. Munitions’ fillers that do not contribute to explosive effects (e.g.
colored and HC smoke, dyes, irritants, WP, PWP, and TPA) are excluded when determining
NEWQD.

C9.2.2. Determining the NEWQD for Mixed HD

C9.2.2.1. General

C9.2.2.1.1. The presence of HD 1.4 does not affect the NEWQD of mixed HD.
However, for QD determinations, HD 1.4 criteria shall be considered.

C9.2.2.1.2. When HD 1.1 is mixed with any other HD, treat the mixture as HD 1.1
except as noted in subparagraph C9.2.2.2.

C9.2.2.1.3. HD 1.5 is always treated as HD 1.1.

C9.2.2.1.4. When dissimilar HD 1.6 are mixed and have not been tested to ensure
non-propagation, the mixed HD 1.6 AE shall be individually considered to be HD 1.2.1 or HD
1.2.2, based on their individual NEWQD or over-riding fragmentation characteristics.

C9.2.2.2. HD 1.1 with HD 1.2 (HD 1.2.1, HD 1.2.2, and HD 1.2.3). Use whichever of
the following generates the largest QD:

C9.2.2.2.1. Sum the NEWQD for HD 1.1 and NEWQD for HD 1.2 and treat the
mixture as HD 1.1.

C9.2.2.2.2. The NEWQD of the mixture is the NEWQD of the HD 1.2 subdivision
requiring the largest QD.

C9.2.2.3. HD 1.1 with HD 1.3. Sum the NEWQD for HD 1.1 and the NEWQD for HD
1.3 and treat the mixture as HD 1.1.

89 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.2.2.4. HD 1.1 with HD 1.6. Sum the NEWQD for HD 1.1 and the NEWQD for HD
1.6 and treat the mixture as HD 1.1.

C9.2.2.5. HD 1.2.1 with HD 1.2.2. The NEWQD for the mixture is the NEWQD of the
subdivision requiring the largest QD.

C9.2.2.6. HD 1.2.1 with HD 1.2.3. The NEWQD for the mixture is the NEWQD of the
subdivision requiring the largest QD.

C9.2.2.7. HD 1.2.2 with HD 1.2.3. The NEWQD for the mixture is the NEWQD of the
subdivision requiring the largest QD.

C9.2.2.8. HD 1.2.1 with HD 1.2.2 with HD 1.2.3. The NEWQD for the mixture is the
NEWQD of the subdivision requiring the largest QD.

C9.2.2.9. HD 1.2 (HD 1.2.1, HD 1.2.2, and HD 1.2.3) with HD 1.3. The NEWQD for
the mixture is the NEWQD of the HD requiring the largest QD.

C9.2.2.10. HD 1.2 (HD 1.2.1, HD 1.2.2, and HD 1.2.3) with HD 1.6. Treat the HD 1.6
as HD 1.2.3 and determine NEWQD in accordance with (IAW) subparagraphs C9.2.2.6. through
C9.2.2.8., as applicable.

C9.2.2.11. HD 1.3 with HD 1.6. Sum the NEWQD for the HD 1.6 and the NEWQD for
the HD 1.3 and treat the mixture as HD 1.3.

C9.3. QD PRINCIPLES

C9.3.1. General

C9.3.1.1. The bases for determining required separation distances (i.e.,QD) are:

C9.3.1.1.1 The HD types and NEWQD of AE present in an AE facility.

C9.3.1.1.2. The NEWQD of the HD requiring the greatest separation establishes the
QD for the facility when it is used for multiple operations.

C9.3.1.1.3. The NEWQD for the HPM is based on its MCE (i.e., the sum of the
contents of an individual open cell and the loading dock, rather than the aggregate NEWQD for
the entire magazine). (The MCE for the HPM shall not exceed 60,000 lbs [27,215 kg].)

C9.3.1.2. The bases for subdividing a quantity of AE into smaller units for the purpose of
QD reduction are provided below.

C9.3.1.2.1. Separation By Time. When two or more stacks of equal NEWQD

detonate within short time intervals, the blast waves will coalesce. A short time interval is

90 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

defined as a time in milliseconds that is less than 4.0W1/3 [5.21Q1/3] of any one stack in lbs [kg]
for lateral (side-to-side) target positions and less than 5.6W1/3 [7.29Q1/3] of any one stack in lbs
[kg] for axial target positions. (In the preceding formulas, the unit for the constant is
milliseconds/lbs1/3 [milliseconds/kg1/3].) The combined shock wave, after coalescence, will be
that of a single detonation of a charge equal to the summation of the several stacks. When
coalescence does not occur, the MCE for the stacks is equal to the NEWQD for one stack.

C9.3.1.2.2. Separation By Barriers. Barriers designed per the principles of Reference

(j) shall ensure no propagation between AE stacks. When barriers are constructed per this
guidance or when supported by test data, the MCE is equal to the NEWQD of the AE stack with
the largest QD requirement. Otherwise, QD computations must be based upon the summation of
NEWQD for all of the AE stacks. (Barrier design shall include adequate standoff distances and
take into account acceptor AE sensitivity.)

C9.3.1.3. The QD criteria for a PES-ES pair, when both contain AE, are determined by
considering each location, in turn, as a PES and an ES. The quantity of AE to be permitted in
each PES shall be the amount permitted by the distance specified in the appropriate QD tables.
The separation distance required for the pair is the greater of the two separation distances. An
exception is permitted for service magazines supporting an AE operation.

C9.3.1.4. Flight ranges for units (e.g., rockets, missile motors, and Cartridge or
Propellant Actuated Devices (CAD/PAD)) in a propulsive state shall be disregarded because it is
impractical to specify QD separations that allow for their designed flight range.

C9.3.1.5. Separation distances are measured along straight lines. For large intervening
topographical features such as hills, measure over or around the feature, whichever is shorter.
For golf courses, measure to the nearest edge of the tee or green or to the centerline of fairways.

C9.3.1.6. Measurements of distance for determining the maximum allowable quantity of

AE shall be made to the nearest part of an ES from:

C9.3.1.6.1. The nearest wall of the PES.

C9.3.1.6.2. The exterior of the nearest intervening wall to the controlling AE stack,
when the PES is subdivided.

C9.3.1.7. When an AE conveyance (e.g., railroad car or motor vehicle) containing AE is

not separated from a PES in such a manner as to prevent mass detonation, then the conveyance
and PES shall be considered as a unit and their NEWQD shall be summed. The separation
distance shall be measured from the nearest outside wall of the PES or conveyance, as
appropriate, to an ES. If the AE are separated so that mass detonation will not occur, the
separation distance shall be measured from the nearest controlling PES or conveyance to an ES.

C9.4. QD CRITERIA FOR ACCIDENTAL DETONATIONS

C9.4.1. HD 1.1.

C9.4.1.1. Permissible Exposures To Airblast Overpressure.

C9.4.1.1.1. 12 psi [82.7 kPa] at 9W1/3 [3.57Q1/3]. (Barricading is required.)

cannot be provided for technical or tactical reasons.

C9.4.1.1.1.1.4. Break rooms and change houses that are both part of an
operating line and used exclusively by personnel operating the line. An exception is when the
break room is integral to the PES and used only by personnel from that PES. For this situation,
no QD applies.

C9.4.1.1.1.1.5. Dunnage preparation or similar non-AE operations, if used

only by personnel employed at the PES.

C9.4.1.1.1.1.6. Temporary holding areas for AE conveyances servicing

minor maintenance, preservation, packaging, or surveillance inspection.

C9.4.1.1.1.1.8. Barricaded service magazines that are part of an operating

line. Separation distances shall be based on the NEWQD and the HD of the AE in the magazine
and not that in other parts of the operating line.

C9.4.1.1.1.2. Exceptions

C9.4.1.1.1.2.1. Unmanned auxiliary utility facilities (e.g., transformer

stations, water treatment and pollution abatement facilities) that serve, but are not an integral
function in the PES, and that would not create an immediate secondary hazard if lost. Such
unmanned facilities need not be barricaded. See subparagraph C9.8.1.2. for situations where
auxiliary facilities serving only one PES or AE operation are permitted to be separated from the
facility or operation they support based on fire separation distance only.

C9.4.1.1.1.2.2. Unmanned auxiliary power generation or conversion facilities

that exclusively supply power to an AE storage area or security fence lighting may be located at

92 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

fire protection distance (50 ft [15.2 m] for non-combustible structures, 100 ft [30.5 m] for
combustible structures) from AE facilities.

C9.4.1.1.2. 3.5 psi [24 kPa] at 18W1/3 [7.14Q1/3].

C9.4.1.1.2.1. Facilities that house:

maintenance, inspection) closely related to the PES.

C9.4.1.1.2.1.2. Buildings, excluding magazine-area loading docks, for

comfort, safety, or convenience (e.g., lunchrooms, motor pools, area offices, auxiliary fire
stations, transportation dispatch points, and shipping and receiving buildings) that are used
exclusively in support of the PES.

C9.4.1.1.2.1.3. Parallel operating lines, whether or not barricaded, provided

the AE involved in each operating line present similar hazards. (The criticality or survivability
of one or more of the operating lines may require that each line be given IBD-level protection.)

C9.4.1.1.2.1.4. Operational support buildings (e.g., day rooms, operation

offices, and similar functions) that only personnel from the activity operating the PES use or
attend.

C9.4.1.1.2.1.5. Training functions (e.g., classroom and field training of

personnel who may be required to engage in AE work) that only personnel from the activity
operating the PES use or attend. (Maneuver areas, proving ground tracks, and similar facilities
for armored vehicles also may be exposed to 3.5 psi [24 kPa] because the vehicles provide
adequate protection to the operators from fragments and debris.)

C9.4.1.1.2.1.6. Maintenance of military vehicles or equipment that are

located outside the United States (U.S.), when the PES is a basic load or a ready storage area. In
such cases:

C9.4.1.1.2.1.6.1. The NEWQD at each PES is limited to 8,818 lbs [4,000

kg] or less.

C9.4.1.1.2.1.6.2. The maintenance work must be performed exclusively

for the unit for which the basic load of AE is stored.

storage and issue; and handling equipment service, battery charging, and minor repair.

C9.4.1.1.2.1.7.1. When such facilities serve an entire naval station or base

complex, or when loss of the facility shall cause an immediate loss of vital function, the
minimum exposure level shall be IBD (40-50W1/3 [15.87-19.84Q1/3]).

93 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.1.2.1.7.2. Naval station “cold-iron” ship support facilities (e.g.,

supply and mechanical support) are excluded from QD criteria when they are not continuously
manned; when they are serving only the waterfront area; and when the PES is a ship or AE
handling location on the waterfront.

C9.4.1.1.2.1.8. Minimum distance between separate groups of AE-loaded,

combat-configured aircraft or between aircraft and a pre-load or “quick-turn” site that serves to
arm an aircraft. The use of intervening barricades is required to eliminate propagation by
primary fragment impact; thereby eliminating the need to total NEWQD. (Loading AE aboard
aircraft can be accomplished with each group of aircraft without additional protection.)

C9.4.1.1.2.1.9. Unbarricaded service magazine separation distances shall be

based on the NEWQD and the HD of the AE in the magazine and not that in other parts of the
operating line.

C9.4.1.1.2.1.10. Container stuffing and unstuffing operations that provide

routine support to a PES and apply only to main support functions that are set aside for support
of ship-loading, depot, or manufacturing operations. When in connection with ship-loading and
unloading and the ES is an AE ship, the quantity at the container site governs. (NOTE:
Container stuffing and unstuffing in a magazine area are permitted at IMD IAW Table C9.T6.)
Criteria applicable to the loading and unloading of a conveyance at a magazine are addressed in
paragraph C9.8.20.

C9.4.1.1.2.1.11. Combat Aircraft Support Facilities

C9.4.1.1.2.1.11.1. Between AE-loaded combat aircraft and those non-AE

facilities that directly support the servicing and launching of a unit’s armed aircraft. Such
facilities include operating facilities that handle AE on the flightline, prepare and service armed
aircraft, and those that house personnel who fly combat aircraft.

C9.4.1.1.2.1.11.2. Direct flightline combat aircraft associated facilities,

which may contain field offices, break rooms, unit training rooms, and equipment and supply
rooms, as well as Petroleum, Oils, Lubricants (POL) hydrant facilities and civil engineer fire
protection stations. (Morale, Welfare, and Recreation (MWR) facilities; base civil engineering
headquarters; and industrial facilities, including central base supply, are required to be at IBD.)

C9.4.1.1.2.1.12. Parking lots for Privately Owned Vehicles (POV) belonging

to personnel employed at or stationed at multiple PES. When a POV parking lot supports a
single PES, it may be separated at less than ILD only from its associated facility; however, a
minimum distance of 100 ft [30.5 m] is required to the PES it supports, to protect the PES from
vehicle fires. Access for emergency vehicles must be provided.

C9.4.1.1.2.2. Exposures indicated in this section that are provided blast

suppression and structure hardening so that comparable protection levels for personnel and
equipment as provided by 18W1/3 [7.14Q1/3] may be sited at 9W1/3 [3.57Q1/3].

94 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.1.3. 2.3 psi [15.8 kPa] at 24W1/3 [9.52Q1/3]. Personnel exposed to remotely
controlled operations.

C9.4.1.1.4. 2.3-1.7 psi [15.8-11.7 kPa] at 24-30W1/3 [9.52-11.9Q1/3].

C9.4.1.1.4.1. PTRD with medium and low traffic densities as described in

subparagraph C9.4.1.2.1.1.5.

C9.4.1.1.4.2. On-base roads. The DoD Components may provide protection less
than 60 percent of IBD to installation-related personnel transiting QD arcs, when the risks are
evaluated, are documented, and are IAW DoD Component-established procedures. (Effective
October 1, 2000, all new construction of AE storage and operating facilities, and any change in
operations within existing facilities that increases the explosive safety risk should provide both
the general public and installation-related personnel who are not involved in munitions-related
operations protection that provides a minimum of 60 percent of IBD.) When a DoD Component
determines exposures at less than 60 percent of IBD to be necessary, the DoD Component should
consider use of methods to inform transients of potential risks (e.g., written acknowledgement of
the risk by vendors or others with a recurring need to transit the ESQD area, warning signs,
flashing lights, physical barriers). The DoD Component’s decision to provide transients’
protection at less than 60 percent of IBD shall be:

C9.4.1.1.4.2.1. Supported by a qualitative risk assessment considering factors

such as:

C9.4.1.1.4.2.1.1. Operational necessity.

C9.4.1.1.4.2.1.2. The operation being performed (e.g., static storage,

maintenance, and production).

C9.4.1.1.4.2.1.3. Operational activity cycles.

C9.4.1.1.4.2.1.4. Alternate routes.

C9.4.1.1.4.2.1.5. Traffic density.

C9.4.1.1.4.2.1.6. Accident records.

C9.4.1.1.4.2.1.7. Time interval of exposure.

C9.4.1.1.4.2.1.10. The need for installation-related personnel to transit the

ESQD arc.

C9.4.1.1.4.2.2. Reviewed as changes occur to either operations, which would

increase the explosive safety risk, or the number of exposed, and upon change of the approving
authority.

C9.4.1.1.4.3. Open-air recreation facilities (e.g., ball diamonds, golf courses, and
volleyball courts), which do not contain structures, used for MWR and community relations’
purposes at military installations and activities. As an exception, neither blast nor fragment
criteria apply, when such facilities are located near AE support operations and used by off-duty
military or on-duty military or DoD civilians or contractors (e.g., munitions workers, security
guards, firefighters) who directly support these AE operations. However, when possible, such
facilities should fully comply with this Standard.

C9.4.1.1.4.4. Training areas (e.g., observation points, classrooms or other

instruction areas for ranges, and similar fixed facilities designed for occasional use coincident
with the use of the range). As an exception, to allow for realism in training, this separation does
not apply to AE needed for any particular exercise or on-the-job training. However, this
separation or equivalent protection is required from permanent PES and AE supply points.

C9.4.1.1.4.5. Open-air aircraft passenger loading and unloading areas.

C9.4.1.1.4.6. Parking lots for administrative areas. (Minimum fragment

distances apply, see subparagraph C9.4.1.2.)

C9.4.1.1.4.7. Inert storage located in the open (no structures involved) when not
directly related to the explosives mission and when accessed by personnel not directly related to
the explosives mission. (See subparagraph C9.4.1.1.6.9. if located within a structure.)

C9.4.1.1.5. 1.7 psi [11.7 kPa] at 30W1/3 [11.9Q1/3]. Combat aircraft parking areas

C9.4.1.1.6.2. An installation boundary, unless the area outside the boundary

naturally prohibits access, is government land that is not open to the public, or access is restricted
and controlled by other means. When IBD QD arcs penetrate an installation’s boundary, the
Service shall certify IBD protection does not apply to the encumbered area and shall establish
procedures to monitor the area for any change in status.

C9.4.1.1.6.3. Recreation facilities (e.g., ball diamonds, golf courses, and

volleyball courts) that contain structures.

96 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.1.6.4. Flight-line passenger service functions (e.g., terminal buildings).

C9.4.1.1.6.5. Main powerhouses that provide vital utilities to a major portion of

an installation.

C9.4.1.1.6.6. Shops that by reason of their vital strategic nature, or high intrinsic
value of their contents, should not be placed at risk.

C9.4.1.1.6.7. Functions that, if momentarily put out of action, would cause an

immediate secondary hazard by reason of their failure to function.

C9.4.1.1.6.8. PTRD with high traffic density as described in subparagraph

C9.4.1.2.1.1.5.

C9.4.1.1.6.9. Inert storage located in a structure when not directly related to the
explosives mission and when accessed by personnel not directly related to the explosives
mission. (See subparagraph C9.4.1.1.4.7. if no structure is involved.)

C9.4.1.2. Minimum Fragment Distances

C9.4.1.2.1. The minimum distance for protection from hazardous fragments shall be
based on primary and secondary fragments from the PES and the population or traffic density of
the ES. It is defined as the distance at which the density of hazardous fragments becomes 1 per
600 ft2 [55.7 m2]. (This distance is not the maximum fragment range.) DDESB-approved
analyses and/or approved tests may be used to determine minimum distances for both primary
and secondary fragments. DDESB TP No. 13 (Reference (o)) is an example of a method to
determine minimal distances for building debris, while DDESB TP No. 16 (Reference (p))
provides similar information to determine minimal distances for primary fragments. In the
absence of appropriate analyses or tests, default hazardous debris distances apply:

C9.4.1.2.1.1. For populous locations provided IBD protection, the minimum

distance shall be the Hazardous Fragment Distance (HFD). If this distance is not known, the
following shall apply:

C9.4.1.2.1.1.1. For all types of Hazard Division 1.1 in quantities < 450 lbs
NEWQD [204 kg], the HFD shall be determined as follows (NOTE: PTRD is 60 percent of the
specified HFD):

C9.4.1.2.1.1.1.1. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM, use

“Earth-Covered Magazine” distances shown in Table C9.T1., as discussed in subparagraph
C9.4.1.3. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.2. For Hazard Division 1.1 in an Undefined ECM, where

the loading density = NEWQD (lbs)/internal volume (ft3) [English EQN C9.4-1] is < 0.028
lbs/ft3 [loading density = NEWQD/internal volume (m3) [Metric EQN C9.4-2] is < 0.449 kg/m3]

97 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

use “Earth-Covered Magazine” distances shown in Table C9.T1., as discussed in subparagraph

C9.4.1.3. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.3. For Hazard Division 1.1 in an Undefined ECM where

the loading density is > 0.028 lbs/ft3 [> 0.449 kg/m3], use “Earth-Covered Magazine - side and
rear” distances of Table C9.T1. and for front exposure, apply the greater of “Earth-Covered
Magazine – front” IBD distance of Table C9.T1. or the HFD from the “STRUCTURE” column
of Table C9.T2., for the NEW in the ECM. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.4. Where ECM, regardless of structural designation, have

been designed, analyzed, or tested to have a reduced IBD and have been approved by the
DDESB, use the approved IBD. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.5. For Hazard Division 1.1 in a structure (excluding ECM)

capable of stopping primary fragments, but which can contribute to the debris hazard, use
hazardous debris and PTRD distances found in Table C9.T10. ILD shall be IAW subparagraph
C9.4.1.4. Structures that are capable of stopping primary fragments include all Heavy Wall (H)
and Heavy Wall/Roof (H/R) AGS, as defined in the legend for Table C9.T8. Doors and other
openings through which primary fragments could exit must be capable of stopping primary
fragments from exiting the facility or shall be barricaded IAW section C5.3. to trap primary
fragments that could exit the facility.

C9.4.1.2.1.1.1.6. For Hazard Division 1.1 in the open or in a structure

incapable of stopping primary fragments, use HFD listed in the “OPEN” column of Table C9.T2.
ILD shall be IAW subparagraph C9.4.1.4. Structures (other than ECM) that are capable of
stopping primary fragments include all H and H/R AGS, as defined in the legend for Table
C9.T8. All other structures (other than ECM) are considered incapable of stopping primary
fragments.

C9.4.1.2.1.1.1.7. Selected items have been evaluated for minimum HFD

with results shown in Table C9.T3. Other items, through testing, have been hazard classified
with a specific HFD presented in the format HD (xx)1.1. The HFD for these items is specified in
hundreds of feet (in parenthesis), and they may not be listed in Table C9.T3. The distances for
these two categories of select items apply only to items in the open. When in facilities,
secondary debris as well as primary fragments must be considered. If in a facility that can
contain primary fragments, apply criteria of subparagraphs C9.4.1.2.1.1.1.1. through
C9.4.1.2.1.1.1.5. If in a facility that cannot stop primary fragments, use the greater distance from
Table C9.T3. (for the item being considered) or the HFD associated with the (xx)(1.1) item or
from Table C9.T2. for determining the applicable HFD. ILD shall be IAW subparagraph
C9.4.1.4.

C9.4.1.2.1.1.1.8. For bare explosives in the open, distance is computed by

the formula d=40W1/3 [15.87Q1/3]. [English EQN C9.4-3] [Metric EQN C9.4-4]

98 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.2.1.1.2. For Hazard Division 1.1 NEWQDs in the range 451 to

30,000 lbs [205 to 13,608 kg], HFD shall be determined according to the below criteria. PTRD
is 60 percent of the specified HFD, and ILD shall be IAW subparagraph C9.4.1.4.

C9.4.1.2.1.1.2.1. The minimum HFD shall be 1,250 ft [381 m], as shown

in Table C9.T1. Lesser distances are permitted if supported by a structural analysis. Facilities
sited at 1,235 ft [376 m] or 1,245 ft [380 m] per past standards shall be considered to be in
compliance with the 1,250 ft [381 m] minimum requirement.

C9.4.1.2.1.1.2.2. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM, use

“Earth-Covered Magazine” distances shown in Table C9.T1., as discussed in subparagraph
C9.4.1.3.

C9.4.1.2.1.1.2.3. For Hazard Division 1.1 in an Undefined ECM, where

the loading density is < 0.028 lbs/ft3 [< 0.449 kg/m3], use “Earth-Covered Magazine” distances
shown in Table C9.T1., as discussed in subparagraph C9.4.1.3.

C9.4.1.2.1.1.2.4. For Hazard Division 1.1 in an Undefined ECM with

minimum internal dimensions of 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Earth-
Covered Magazine - side and rear” distances of Table C9.T1. and “Other PES” distance of Table
C9.T1. for the front exposure.

C9.4.1.2.1.1.2.5. For Hazard Division 1.1 in an Undefined ECM where

the loading density is > 0.028 lbs/ft3 [> 0.449 kg/m3] and internal dimensions are less than 26 ft
[7.92 m] wide and 60 ft [18.29 m] long, use “Other PES” distances of Table C9.T1. for front,
side, and rear exposures.

C9.4.1.2.1.1.2.6. Selected items have been evaluated for minimum HFD

with results shown in Table C9.T3. Other items, through testing, have been hazard classified
with a specific HFD presented in the format HD (xx)1.1. The HFD for these items is specified in
hundreds of feet (in parenthesis), and they may not be listed in Table C9.T3. The distances for
these two categories of select items apply only to items in the open. When these items are placed
in a facility, apply the criteria of subparagraphs C9.4.1.2.1.1.2.1. through C9.4.1.2.1.1.2.5. as
appropriate.

C9.4.1.2.1.1.2.7. For bare explosives in the open, distance is computed by

the formula d=40W1/3 [15.87Q1/3]. [English EQN C9.4-3] [Metric EQN C9.4-4]

C9.4.1.2.1.1.3. For Hazard Division 1.1 NEWQDs > 30,000 lbs [13,608 kg]
HFD will be in accordance with Table C9.T1. Lesser distances are permitted if supported by a
structural analysis. PTRD is 60 percent of HFD and intraline criteria will be in accordance with
subparagraph C9.4.1.4. The following apply to use of the reduced “Earth-Covered Magazine”
distances shown in Table C9.T1., for the NEW range between 30,000 lbs [13,608 kg] and
250,000 lbs [113,398 kg]

DoD 6055.09-STD, February 29, 2008

Notes for Table C9.T3.:

1. Ten units or more until the point is reached at which this distance is exceeded by the distance requirements of
Table C9.T1.
2. Use the distance shown only where there are less than 25 unrelated people exposed in any arc encompassing 45
degrees from 900 ft [274 m] to 1250 ft [381 m] from the PES.
3. More than 10 units may be involved before 1250 ft [381 m] is exceeded. For distances involving more than 10
units consult the applicable Service guidance.
4. When handling more than one missile, the missiles must be transported or handled in a nose-to-tail
configuration and in their launch capsule or shipping container; furthermore, they must be aligned and/or
handled so that each group of two missiles is located outside of the warhead fragment beam spray region of the
other two missiles.

General Comments for Table C9.T3.:

(a) Items identified by an asterisk “*” include fragments from shipping or storage container(s). However, all of the
HFD in this table may be applied to both packaged and unpackaged configurations.
(b) Those items with WAU-17 warhead.
(c) 105-mm projectiles and 105-mm complete rounds not in standard storage or shipping containers are HD 1.1.
(d) All models, including Advanced Capability (ADCAP).
(e) These distances must be used when handling torpedo(es) from motor vehicles where sandbag (or other
equivalent) shielding (as described in Note (f)) is not present between the leading edge of the torpedo(es)
warhead and the motor vehicle engine compartment/crew cab to prevent the engine compartment/crew cab from
contributing to the debris.
(f) These distances may be used when handling torpedo(es) from:
(i) Motor vehicles with sandbag (or other equivalent) shielding between the leading edge of the torpedo(es)
warhead and the motor vehicle engine compartment/crew cab to prevent the engine compartment/crew cab
from contributing to the debris, or
[NOTE: Sandbag shield requirement is equivalent to a minimum thickness of 2 ft [0.61 m] of sand
between the engine compartment/crew cab and the torpedo(es). The sandbags must shield all parts of the
engine compartment/crew cab from the torpedo warhead.]
(ii) Other means of transport such as boats, torpedo transporters, forklifts, or portable cranes.

C9.4.1.2.1.1.3.1. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM,

where internal dimensions are a minimum of 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use
“Earth-Covered Magazine” distances shown in Table C9.T1.

C9.4.1.2.1.1.3.2. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM,

where internal dimensions are less than 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Other
PES” distances of Table C9.T1. for front, side, and rear exposures.

C9.4.1.2.1.1.3.3. For Hazard Division 1.1 in an Undefined ECM, where

internal dimensions are a minimum of 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Earth-
Covered Magazine - side and rear” distances of C9.T1. and “Other PES” distance of Table
C9.T1. for the front exposure.

C9.4.1.2.1.1.3.4. For Hazard Division 1.1 in an Undefined ECM, where

internal dimensions are less than 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Other PES”
distances of Table C9.T1. for front, side, and rear exposures.

C9.4.1.2.1.1.4. For sparsely populated locations (i.e., no more than 25

persons located in any sector bounded by the sides of a 45-degree angle, with the vertex at the

106 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

PES, and the 900 ft [274 m] and 1,250 ft [381 m] arcs from the PES), the minimum 1,250 ft [381
m] fragment distance may be reduced to 900 ft [274 m] if the NEWQD of the PES does not
exceed 11,400 lbs [5,171 kg].

C9.4.1.2.1.1.5. For PTR, the minimum fragment distance for HD 1.1 AE shall
be based on the traffic density considered at three levels: high, medium, and low traffic density.
The traffic density shall be averaged over a normal (non-holiday) week in terms of number of
passengers during a 24-hour period. Minimum fragment distance reductions based on sparse
population considerations addressed above, do not apply to public traffic routes. (NOTE: In
applying criteria other than the default values given below (which are based on car (and rail)
speed of 50 mph [80 kph], and a ship speed of 10 mph [16 kph]), considerations such as the
following shall be taken into account to establish exposure levels: speed of vehicles, number of
passengers per vehicle, protection afforded by the vehicle, variation in daily traffic levels in
relation to AE activities, and seasonal traffic trends. The default value of two passengers per car
may be used to estimate traffic density.

C9.4.1.2.1.1.5.1. High Traffic Density. If routes have 10,000 or more car

or rail passengers per day, or 2,000 or more ship passengers per day, then IBD criteria apply.

C9.4.1.2.1.1.5.2. Medium Traffic Density. If routes have between 400

and 10,000 car or rail passengers per day, or between 80 and 2,000 ship passengers per day, then
60 percent of the specified minimum fragment distance for IBD applies. As a minimum, these
criteria apply to any recreational activity that is extensive and occurs on a regular basis.

C9.4.1.2.1.1.5.3. Low Traffic Density. If routes have fewer than 400 car
or rail passengers per day, or fewer than 80 ship passengers per day, then no minimum fragment
distance is required. Minimum distance shall be based on blast criteria (24W1/3/30W1/3
[9.52Q1/3/11.9Q1/3]).

C9.4.1.2.1.1.5.4. For other exposures that are permitted at PTRD,

fragment distance minimal for HD 1.1 AE shall be at least 60 percent of the specified minimum
fragment distance for IBD.

C9.4.1.2.1.2. Minimum fragment distances apply to:

C9.4.1.2.1.2.1. An installation’s boundary unless the area outside the

boundary naturally prohibits access or is government land that is not open to the public. When a
QD arc extends beyond an installation’s boundary, and the above exclusion applies, the DoD
Component shall certify IBD protection need not be applied to the encumbered area and shall
establish procedures to monitor the area for any change in status.

C9.4.1.2.1.2.2. Administration and housing areas.

C9.4.1.2.1.2.3. Recreation facilities (e.g., ball diamonds, golf courses, and

volleyball courts). (See subparagraph C9.4.1.2.1.3.1. for situations where minimum fragment
distances do not apply to recreational facilities.)

107 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.2.1.2.4. Flight-line passenger service functions (e.g., terminal

buildings).

C9.4.1.2.1.2.5. Main powerhouses that provide vital utilities to a major

portion of an installation.

C9.4.1.2.1.2.6. Inert storage and shops that by reason of their vital strategic
nature, or high intrinsic value of their contents, should not be placed at risk.

C9.4.1.2.1.2.7. Functions that, if momentarily put out of action, would cause

an immediate secondary hazard by reason of their failure to function.

C9.4.1.2.1.2.8. Private vehicles parked in administrative areas.

C9.4.1.2.1.3. Examples when minimum fragment and firebrand distances need

not apply are:

C9.4.1.2.1.3.1. Recreation or training facilities when such facilities are

located near AE support operations and are used by off-duty military or on-duty military or DoD
civilians or contractors (e.g., munitions workers, security guards, and firefighters) who directly
support these AE operations.

C9.4.1.2.1.3.2. Related and support DoD-controlled functions for which IMD

and ILD would normally apply.

C9.4.1.2.1.3.3. Maintenance, supply, training facilities, and operations offices

for logistical or operational support of combat aircraft, battalion-size or smaller delivery or AE
supply units, separate air defense firing batteries, or a single pier or wharf for which the AE in a
PES is intended.

C9.4.1.2.1.3.4. Between a PES and inert storage, whether in a facility or in

the open.

C9.4.1.2.1.3.5. Between facilities in an operating line; between operating

lines; and between operating lines and storage locations.

C9.4.1.3. IBD and PTRD. Subparagraph C9.4.1.2.1.1. specifies required separation

distances to inhabited buildings and public traffic routes for ECM and other types of PESs
containing HD 1.1. Permissible exposures at these distances are listed in subparagraphs
C9.4.1.1.4. through C9.4.1.1.6.

C9.4.1.3.1. ECM. Specified separations from ECM consider reductions in blast

overpressure attributable to the earth cover of ECM, when the earth cover has a minimum
thickness of 2 ft [0.61 m]. See subparagraph C9.4.1.2.1.1. for application of “Earth-Covered

Magazine” distances of Table C9.T1. to 7-Bar, 3-Bar, and Undefined ECM. The definitions for
“front,” “side,” and “rear” for ECM are illustrated in Figure C9.F1. and are described below:

C9.4.1.3.1.1. The forward sector, or “front,” for ECM is that area 60 degrees
either side of the ECM’s centerline (120 degrees combined angle), with the vertex of the angle
placed so that the sides of the angle pass through the intersection of the headwall and sidewalls.

C9.4.1.3.1.2. The rear sector, or “rear,” of an ECM is that area 45 degrees either
side of the magazine centerline (90 degrees combined angle) with the vertex of the angle placed
so that the sides of the angle pass through the intersection of the rear and side walls.

C9.4.1.3.1.3. All other orientations are considered “side” sectors.

C9.4.1.3.2. HPM. Testing has shown that the design of the earth-bermed HPM
attenuates pressures relative to an unconfined surface burst similar to that indicated above for an
ECM. The following pertain to siting of an HPM:

C9.4.1.3.2.1. An HPM has a “front” sector and a “side” sector. The definition of
“front” for ECM (see subparagraph C9.4.1.3.1.1.) applies to an HPM. All other orientations are
considered “side” sectors. Figure C9.F8. illustrates the sectors associated with an HPM.
(NOTE: An HPM has no “rear” sector.)

C9.4.1.3.2.2. The values shown in Table C9.T4. for front exposure from an ECM
also apply to the front of an HPM.

C9.4.1.3.2.3. The values shown in Table C9.T4. for side exposure from an ECM
apply to the remainder (all but the front) of an HPM.

C9.4.1.4. ILD. Separation distances required between AE and non-AE buildings and
sites within an AE operating line are listed for various quantities of HD 1.1 AE in Table C9.T5.
Permissible exposures at ILD are listed in subparagraphs C9.4.1.1.1. (barricaded ILD) and
C9.4.1.1.2. (unbarricaded ILD). In order to apply barricaded ILD, barricades must comply with
paragraph C5.3.2. (The separation distance between an operating building and its service
magazine shall be based on the NEWQD and the HD of the AE in the magazine and not that in
other parts of the operating line.)

C9.4.1.4.1. ILD from ECM. Testing has shown that some attenuation of airblast
overpressure relative to an unconfined surface burst occurs out the sides and rear of an ECM and
a slight increase occurs out the front of an ECM. The equivalent 9W1/3 [3.57Q1/3] (12 psi [82.7
kPa] (barricaded)) and 18W1/3 [7.14 Q1/3] (3.5 psi [24 kPa] (unbarricaded)) ILD from an ECM,
when accounting for this attenuation, are given in Table C9.T4. (Airblast forms the bases for the
equations given in the notes for Table C9.T4.)

C9.4.1.4.2. Barricaded ILD from an ECM. Subparagraph C9.4.1.5.4. provides

criteria for the application of barricaded ILD from an ECM.

109 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.4.3. ILD from HPM. The values shown in Table C9.T4. for front exposure
from an ECM also apply to front exposures from an HPM. The values shown in Table C9.T4.
for side exposure from an ECM apply to all other orientations of an HPM. (The side of an HPM
is considered barricaded, provided the earth barricading complies with the design drawing.)

C9.4.1.5. IMD. Magazines for HD 1.1 shall be separated one from another per Tables
C9.T6., C9.T7A., and C9.T7B. (NOTE: Table C9.T6. provides orientation relationships for
ECM and Tables C9.T7A. and C9.T7B. provide the actual separation distances.)

C9.4.1.5.1. Siting Rules. For examples of siting rules for various magazine
orientations see Figures C9.F1. through C9.F8.

C9.4.1.5.2. Barricaded IMD from ECM. Subparagraph C9.4.1.5.4. provides criteria

for the application of barricaded IMD from ECM.

C9.4.1.5.3. Other Factors Limiting ECM Storage. Other factors limiting ECM
storage include:

C9.4.1.5.3.1. Quantities above 500,000 lbs [226,795 kg] NEWQD in one ECM
are not authorized, except for energetic liquids.

C9.4.1.5.3.2. The 7-foot separation distance given in Table C9.T7A. for 100 lbs
[45.4 kg] NEWQD constitutes the minimum side-to-side magazine separation distance.

C9.4.1.5.4. Application of Barricaded ILD and Barricaded IMD from an ECM.

Figure C9.F7. illustrates the IMD relationships that can exist between an ECM and AGM and the
ILD relationships that can exist between an ECM and facilities permitted to be at ILD or
barricaded ILD from an ECM, when each contain HD 1.1 AE. Permissible exposures at ILD are
listed in subparagraphs C9.4.1.1.1. (barricaded ILD) and C9.4.1.1.2. (unbarricaded ILD). Siting
criteria for AGM are provided in Table C9.T6. The following criteria shall apply to the use of
barricaded IMD for AGM and for use of barricaded ILD:

C9.4.1.5.4.1. Front Sector of an ECM. Use of barricaded ILD or barricaded

IMD, as applicable, between an ECM and a facility located within the ECM’s front sector
requires that a properly constructed, intervening barricade be located between the ES and the
PES. This barricade must meet the construction and location criteria of section C5.3. If it does
not meet these criteria, then unbarricaded IMD or unbarricaded ILD, as applicable, shall be used
for siting purposes.

C9.4.1.5.4.2. Side and Rear Sectors of an ECM. If an ECM’s earth cover meets
all construction criteria of section C5.3., it will qualify as a barricade, and use of barricaded ILD
or barricaded IMD, as applicable, from the sides or rear of the ECM is permissible. Failure of
the ECM’s earth cover to meet these criteria shall require use of unbarricaded IMD or
unbarricaded ILD, as applicable, for siting purposes.

110 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.5.5. Application of Barricaded ILD and Barricaded IMD from an HPM.

Permissible exposures at ILD are listed in subparagraphs C9.4.1.1.1. (barricaded ILD) and
C9.4.1.1.2. (unbarricaded ILD). Siting criteria for HPM containing HD 1.1 are provided in
Table C9.T6. The following applies to an HPM:

C9.4.1.5.5.1. Front Sector of an HPM. Use of barricaded ILD or barricaded

IMD, as applicable, between an HPM and a facility located within the HPM’s front sector
requires that a properly constructed, intervening barricade be located between the ES and the
PES. This barricade must meet the construction and location criteria of section C5.3. If it does
not meet these criteria, then unbarricaded IMD or ILD, as applicable, shall be used for siting
purposes.

C9.4.1.5.5.2. Side Sector of an HPM. If the earth berm surrounding an HPM

meets all construction criteria shown on the DDESB-approved construction drawing, it will
qualify as a barricade and use of barricaded ILD or barricaded IMD, as applicable, from the
HPM’s sides is permissible. Failure to meet these criteria shall require use of unbarricaded IMD
or unbarricaded ILD, as applicable, for siting purposes.

C9.4.1.5.6. These IMD standards apply only to storage of HD 1.1 AE. Existing
ECM, regardless of orientation, that meet the construction and barricading requirements of
Chapter 5 and are sited one from another for a minimum of 100 lbs [45.4 kg] NEWQD of HD
1.1 may be used to their physical storage capacity for HD 1.2, HD 1.3, and HD 1.4 AE, provided
distances to other exposures comply with applicable QD requirements.

3. For less than 50 lbs [22.7 kg], less distance may be used when structures, blast mats, and the like can
completely contain fragments and debris. This table is not applicable when blast, fragments, and debris are
completely confined, as in certain test firing barricades.

4. Quantities above 500,000 lbs [226,795 kg] NEWQD are authorized only for HD 1.1 energetic liquids.

DoD 6055.09-STD, February 29, 2008

3. A description of an HPM can be found at paragraph C5.2.4. Additional information is provided in

subparagraph C9.4.1.3. The MCE in an HPM is limited to a maximum of 60,000 lbs [27,216 kg].
4. The unbarricaded front (entrance to loading area) is a factor when the HPM is the PES because the MCE
includes AE in the loading area. The hazard factors have been determined accordingly.
5. Those barricades serve to mitigate both fragments and overpressure hazards. (See section C5.3. for their
requirements.)
6. Use this K-factor for NEWQD in PES up to 250,000 lbs [113,398 kg].
7. Use this K-factor for NEWQD in PES greater than 250,000 lbs [113,398 kg].
8. Modules and/or cells are defined in paragraph C5.2.2.
9. The storage areas in the HPM are barricaded on all sides and protected by a reinforced concrete cover. All
directions are, therefore, considered to be Side (S) orientations when it is the ES. For siting purposes, an HPM
has no Rear (R) sector. See Figure C9.F8. for an illustration of the front and side sectors of an HPM.

C9.4.2. HD 1.2

C9.4.2.1. General

C9.4.2.1.1. HD 1.2 are items configured for storage and transportation that do not
mass detonate when a single item or package in a stack is initiated. Explosions involving the
items result in their burning and exploding progressively with no more than a few at a time
reacting. These reactions will project fragments, firebrands, and unexploded items from the
explosion site. Blast effects are limited to the immediate vicinity and are not the primary hazard.

C9.4.2.1.2. Small quantities of HD 1.2.1 (< 450 pounds NEWQD [204 kg],), in
certain packaging configurations, will react in a manner more typical of an HD 1.1 event. When
located in structures that stop primary fragments, but which generate a secondary debris hazard
(e.g., certain ECM and hardened structures), the structural damage and debris hazards produced
from these events are more characteristic of an HD 1.1 explosion, rather than the progressive
nature of an HD 1.2.1 event. When the NEWQD and the MCE of the packaged HD 1.2.1 items
fall within the ranges specified in equation {NEWQD < MCE < 450 lbs [204 kg]}, the HD 1.2.1
shall be treated as HD 1.1 and the criteria of subparagraph C9.4.1.2.1.1.1., as applicable, shall be
used. If they fall outside the ranges of the equation, then the criteria of Table C9.T8. shall be
applied.

C9.4.2.2. The NEW of an HD 1.2 item (used for transportation) is the sum of the weight
of the HD 1.1 and 1.3 material contained within the item. The NEWQD for an item is equal to
NEW (NEWQD = NEW) unless testing has been conducted. Based on testing, the NEWQD
may include a reduced contribution (less than or equal to 100 percent) from the HD 1.3 material
as a result of the HD 1.1 material being functioned. The NEWQD should be determined by the
Single Package Test (UN Test 6 (a) or its equivalent), not the Bonfire Test (UN Test 6 (c)). The
NEWQD for a specific item may be obtained from the JHCS. The effects produced by the
functioning of HD 1.2 items vary with the size and weight of the item. HD 1.2 AE is separated
into two subdivisions in order to account for the differences in magnitude of these effects for
purposes of setting QD criteria. The more hazardous items are referred to as HD 1.2.1 items.
The less hazardous items are referred to as HD 1.2.2. These two HD 1.2 subdivisions are shown
below with their definitions (NOTE: It is important not to exaggerate the significance of the
value of 1.60 lbs [0.73 kg] used above. It is based on a break point in the database supporting
the quantity-distance relationships and tables and the NEWQD of the rounds tested. If
comprehensive data are available for a particular item, then the item may be placed in that
category of HD 1.2 supported by the data and allocated the relevant quantity-distances.):

C9.4.2.2.1. HD 1.2.1: NEWQD > 1.60 lbs [0.73 kg]

C9.4.2.2.2. HD 1.2.2: NEWQD < 1.60 lbs [0.73 kg]

C9.4.2.3. The MCE for HD 1.2.1 is the NEWQD of an item times the number of items in
three unpalletized, outer shipping packages, unless a different MCE is demonstrated by testing or
analogy. The authorized MCE for a specific HD 1.2.1 item is listed in the JHCS.

126 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.2.4. The QD specified for HD 1.2 AE achieve the desired degree of protection
against immediate hazards from an incident. Events involving HD 1.2 items lob large amounts
of unexploded rounds, components, and subassemblies, which will remain hazardous after
impact. Such items are likely to be more hazardous than in their original state because of
possible damage to fuze safety devices or other features by heat and impact. Many types of AE
containing sub-munitions, such as cluster bombs, can be expected to be projected out to distances
as great as the relevant inhabited building distances. Furthermore, it is impractical to specify
quantity distances, which allow for the maximum possible flight ranges of propulsive items.

C9.4.2.5. Table C9.T8. provides a summary matrix of all the appropriate IBD, PTRD,
and ILD separations for HD 1.2.1 and HD 1.2.2 AE, for the various combinations of ES and
PES. When HD 1.2.1 items are stored in structures that may contribute to the debris hazard, the
IBD is determined by using the larger of the following two distances: either that given in Table
C9.T9. for the appropriate Explosive Weight (number of items x NEWQD) or that given in Table
C9.T10. for the appropriate MCE. (Hazardous Debris Distance (HDD) specified in Table
C9.T10. equates to IBD.)

C9.4.2.6. IMD are dependent upon the types of structures acting as both the PES and the
ES.

C9.4.2.7. PTRD given in Tables C9.T8. through C9.T11. give consideration to the
transient nature of the exposure in the same manner as for HD 1.1. PTRD is computed as 60
percent of the IBD for items in this HD, with minimum distances specified in Table C9.T8.

C9.4.2.8. ILD given in Tables C9.T8. through C9.T11. take into account the progressive
nature of explosions involving these items (normally resulting from fire spread), up to the
magnitude of the MCE, and the ability to evacuate personnel from endangered areas before the
progression involves large numbers of items. Exposed structures may be extensively damaged
by projections and delayed propagation of explosions may occur due to the ignition of
combustibles by projections. ILD is computed as 36 percent of the IBD for items of this HD,
with a minimum distance equal to the IMD given in Table C9.T8. for the applicable PES-ES
combination.

C9.4.2.9. When storing mixed subdivisions of HD 1.2 AE (HD 1.2.1 and HD 1.2.2), the
following rule shall apply: Consider each subdivision separately and apply the greater of the two
distances. The general mixing rules for HD 1.2 AE are given in Table C9.T12.

C9.4.2.10. For reasons of operational necessity, limited quantities of HD 1.2.2 items may
be stored in facilities such as hangars, troop buildings, and manufacturing or operating buildings
without regard to quantity distance. Fragmentation shielding shall be provided.

C9.4.2.11. HD 1.2.3 is a special storage subdivision for HD 1.2 AE (see subparagraph

C3.2.1.2.3.).

127 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.2.12. The IBD for HD 1.2.3 is determined using Table C9.T13. (HD 1.3 QD) for
the NEWQD of the HD 1.2.3 item multiplied by the number of rounds present, but with a
minimum IBD determined as follows:

AGS (L)—Aboveground Structure, Light; Light structure, open stack, truck, trailer, or railcar (open stacks—see
Note 4).

Notes for Table C9.T8.:

1. Practical considerations such as firefighting and security will dictate specific separation distances as specified
by DoD Component.
2. ILD = 36 percent of IBD with a minimum distance equal to the IMD given in this table for the applicable PES-
ES combination.
3. PTRD = 60 percent of IBD with a minimum distance equal to the IMD given in this table for light structures,
open stacks, trucks, trailers, or rail cars. Such structures are designated as AGS (L).
4. For HD 1.2.1 items in any structure, truck, trailer, or railcar, use the larger of the two applicable values given in
Tables C9.T9. and C9.T10.; for HD 1.2.1 items in the open, use Table C9.T9.; for HD 1.2.2 items, use Table
C9.T11.
5. See subparagraph C9.4.2.12. for HD 1.2.3.
6. When the NEWQD and the MCE of the packaged HD 1.2.1 items fall within the ranges specified in equation
{NEWQD < MCE < 450 lbs [204 kg]}, the HD 1.2.1 shall be treated as HD 1.1 and the criteria of subparagraph
C9.4.1.2.1.1.1., as applicable, shall be used (see subparagraph C9.4.2.1.2.).

General Comments for Table C9.T8.:

129 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

(a) For PES-ES combinations where three distances are given: the first refers to a PES containing HD 1.2.1 AE
with an MCE < 100 lbs [45.4 kg]; the second to a PES containing HD 1.2.1 AE with an MCE > 100 lbs [45.4
kg]; and the third refers to a PES containing HD 1.2.2 AE. Where three IMD are given, the IMD from a PES
containing only HD 1.2.3 AE to an ES containing other than HD 1.2.3 is K11 [4.36] based on the NEWQD of a
single round of the largest (greatest NEWQD) HD 1.2.3 AE in the PES.
(b) For an ES containing only HD 1.2.3 items, the IMD from any PES to such an ES is 0 (Note 1).

General Comments for Table C9.T9.:

(a) The QD criteria for HD 1.2.1 items are based on the hazards from primary fragments. When stored in structures
that may contribute to the debris hazard (secondary fragments), the IBD for HD 1.2.1 items whose MCE is
greater than 31 lbs [14.1 kg] is determined by using the larger of two distances: those given in this table for the
appropriate explosive weight or those given in Table C9.T10. for the appropriate MCE. Structures that may
contribute to the debris hazard for storage of HD 1.2.1 AE include: (a) all ECM frontal exposures (side and rear
exposures have fixed minimum distances for IBD); (b) all AGS, including heavy wall (H), heavy wall and roof
(H/R), and light (L) as defined in C9.T8., unless data/analyses are provided to show that the structural debris
contribution is less. Note that ILD and PTRD are based on 36 percent and 60 percent, respectively, of the
applicable IBD as determined in this note with minimum distances of: ILD minimum distances are given in
Table C9.T8. for applicable PES-ES combinations and PTR minimum distances are given in Table C9.T8. for
AGS (L).

Notes for Table C9.T11.:

1. Explosive Weight = Number of Items x NEWQD.
2. IBD in ft, NEWQD in lbs; ln is natural logarithm.
[20 lbs < Explosive Weight]
IBD = 101.649 - [15.934 x (ln(Number of items x NEWQD))] + [5.173 x (ln(Number of items x NEWQD))2],
with a minimum of 100 ft [English EQN C9.T11-1]
IBD in m, NEWQD in kg; ln is natural logarithm
[9.1 kg < Explosive Weight]
IBD = 28.127 - [2.364 x (ln(Number of items x NEWQD))] + [1.577 x (ln(Number of items x NEWQD))2]
with a minimum of 30.5 m [Metric EQN C9.T11-2]
3. IBD in ft, NEWQD in lbs; exp (x) is ex.
[100 ft <IBD < 1240 ft]
Number of items x NEWQD = exp [1.5401 + (-17.278 + 0.1933 x IBD)1/2] [English EQN C9.T11-3]
IBD in m, NEWQD in kg; exp (x) is ex.
[30.5 m <IBD < 378 m]
Number of items x NEWQD = exp [0.7495 + (-17.274 + 0.6341 x IBD)1/2] [Metric EQN C9.T11-4]
4. Use of equations given in Notes (2) and (3) to determine other IBD-weight combinations is allowed
5. PTRD = 60 percent of IBD with a minimum distance equal to the IMD given in Table C9.T8. for AGS (L). For
other structures as either ES or PES, see Table C9.T8.
6. ILD = 36 percent of IBD with a minimum distance equal to the IMD given in Table C9.T8. for the applicable
PES-ES combination. For structures other than AGS (L) as either ES or PES, see Table C9.T8.

General Comments for Table C9.T11.:

(a) The QD criteria for HD 1.2.2 items are based on the hazards from primary fragments.
(b) See Table C9.T8. for a summary of IMD and minimum distances for ILD and PTRD.
(c) For operational necessity, limited quantities of HD 1.2.2 may be stored without regards to QD. See
subparagraph C9.4.2.10

1.2.1 + 1.2.2 Apply greater of two distances
1.2.1 + 1.2.3 Apply greater of two distances
1.2.2 + 1.2.3 Apply greater of two distances

Notes for Table C9.T12.:

1. HD 1.2.1 distances given in Tables C9.T8., C9.T9, and C9.T10.
2. HD 1.2.2 distances given in Tables C9.T8. and C9.T11.
3. HD 1.2.3 distances given in Table C9.T13. (See subparagraph C9.4.2.12.)

C9.4.2.12.1. If the AE are in a structure that can interrupt primary fragments and can
contribute debris, the minimum IBD is the hazardous debris distance given in Table C9.T10. for
an MCE equal to the NEWQD of a single round.

C9.4.2.12.2. If the AE are in the open or in a light structure that will not interrupt
primary fragments, the minimum IBD is the HFD based on the HD 1.1 hazardous fragment areal
number density criteria applied to a single HD 1.2.3 item. The HFD applicable to AE in the
open is specified in hundreds of ft in parentheses as “(xx) HD 1.2.3.”

C9.4.2.12.3. As an alternative to the preceding HD 1.2.3 QD criteria, when an

increase in the allowable quantity or a reduction in the required distance will result, HD 1.2.3 AE
may be treated as follows:

C9.4.2.12.3.1. If the single-round NEWQD is > 1.6 lbs [0.73 kg], consider the
items as HD 1.2.1. Use the total NEWQD present, with an MCE equal to the NEWQD of one
round to determine the maximum QD.

C9.4.2.12.3.2. If the single-round NEWQD is < than 1.6 lbs [0.73 kg], consider
the items as HD 1.2.2, based on the total NEWQD present.

C9.4.2.13. For storage of mixed HD 1.2.3 AE, multiply the NEWQD for the HD 1.2.3
items by the corresponding number of HD 1.2.3 rounds and use Table C9.T13. with the HFD for
the mixture based on the largest HFD for the HD 1.2.3 AE in storage. Use the distances given in
Table C9.T12., when HD 1.2.3 AE is located with any other HD 1.2 sub-division. The HD 1.2.3
AE is considered HD 1.2 (HD 1.2.1 or HD 1.2.2, according to NEWQD) for QD purposes, when
HD 1.2.3 AE is located with any other HD AE. The mixing rules provided in paragraph C9.2.2.
then apply to the combination of the hazard divisions.

139 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.3. HD 1.3. HD 1.3 includes items that burn vigorously with little or no possibility of
extinguishment in storage situations. Explosions normally will be confined to pressure ruptures
of containers and will not produce propagating shock waves or damaging blast overpressure
beyond the magazine distance specified in Table C9.T13. A severe hazard of spread of fire may
result from tossing about of burning container materials, propellant, or other flaming debris.

C9.4.4. HD 1.4

C9.4.4.1. HD 1.4 AE present a fire hazard with minimal blast, fragmentation, or toxic
hazards. Separate facilities for storage and handling of these AE shall be located IAW Table
C9.T14.

C9.4.4.2. In mixed storage, the NEWQD of HD 1.4 is not additive (see subparagraph
C9.2.2.1.1.). However, QD criteria for each HD present, including HD 1.4, must be determined
and the largest value shall be used.

C9.4.4.3. HD 1.4S AE (see paragraph C2.5.5.) may be stored (including associated

handling) without regard to the QD criteria in Table C9.T14.

C9.4.5. HD 1.6. QD separations for HD 1.6 AE shall be based on the storage location and
configuration. This information is detailed in Table C9.T15. and its footnotes. A maximum of
500,000 lbs [226,795 kg] NEWQD shall be permitted at any one location. Any special storage
configuration and siting approved for HD 1.1 AE may be used for storage of like explosive
weights of HD 1.6 AE.

C9.4.6. HD 6.1

C9.4.6.1. HD 6.1 includes items that contain only toxic chemical or riot control agents.
AE containing both explosives and toxic chemical or riot control agents may be hazard classified
as HD 1.1 through HD 1.4, based on testing IAW Reference (e).

C9.4.6.2. Hazard zones for toxic chemical agents are determined by the relative toxicity
of the agents, the amount released to the atmosphere and the rate at which they are released (that
is, evaporation, pressure, or explosive dispersal), terrain features, and meteorological conditions.
Hazard zone calculations are based on MCE, using DDESB TP No. 10 (Reference (q)). (See
Chapter 11 for specific criteria associated with toxic chemical agents.)

C9.4.6.3. When siting AE containing toxic chemical agents, both the explosives and
toxic chemical agent hazards shall be evaluated with the greatest QD governing siting.

General Comments for Table C9.T13.:

(a) For reasons of operational necessity, limited quantities of items in this hazard division, such as document
destroyers, signaling devices, riot control munitions and the like, may be stored without regard to QD IAW fire
protection regulations in facilities such as hangars, arms rooms, and manufacturing or operating buildings.
(b) ECM may be used to their physical capacity for this HD provided they comply with the construction and siting
requirements of Chapters 5 and 9, respectively, for HD 1.1. ECM used to store only HD 1.3 items must be sited
for a minimum of 100 lbs [45.4 kg] of HD 1.1 items using Tables C9.T4. (ILD) and C9.T6. (IM). Use IBD and
PTRD columns of Table C9.T13. for determining the IBD and PTRD associated with the HD 1.3 being placed
in such ECM.

Notes for Table C9.T14.:

1. Magazines storing only HD 1.4 AE may be located at these IMD or ILD from all other magazines or operating
buildings regardless of the HD or NEWQD authorized in those adjacent structures. Because the HD 1.4 AE
may be destroyed as the result of an accident involving the assets in those adjacent structures, the DoD
Component on a case-by-case basis must accept application of this provision with consideration given to the
value of HD 1.4 assets at risk.
2. HD 1.4 AE may be stored in a general supplies warehouse area rather than in an AE storage area. When storing
in a general supplies warehouse area, any weatherproof warehouse structure may serve as an HD 1.4 magazine.
Such a structure will be separated from all other warehouses by AGM distance.
3. For reasons of operational necessity, limited quantities of HD 1.4 AE (e.g., small arms AE and riot control
munitions) may be stored within facilities (e.g., hangars, arms rooms, and operating buildings) without regard to
QD. Alternatively, operationally necessary HD 1.4 AE may be stored in small magazines external to those
facilities without regard to QD.
4. See subparagraph C9.2.2.1.1. for the applicability of HD 1.4 QD criteria and the determination of NEWQD
when HD 1.4 and other HD AE are located in the same site.

C9.5. ENERGETIC LIQUIDS

C9.5.1. Scope and application

C9.5.1.1. This section applies to the storage of energetic liquids, listed in Table C9.T16.,
in all types of containers, including rocket and missile tankage. Laboratory quantities shall be
stored and handled as prescribed by the controlling DoD Component. (NOTE: The required QD
are only based on the energetic liquids’ energetic reaction (blast overpressure and container
fragmentation). These QD requirements do not consider the toxicity or potential down-wind
hazard. Therefore, QD may not be the only factor that needs to be considered when selecting a
location for storage and operations of energetic liquids.)

C9.5.1.2. This section does not govern the storage or handling of energetic liquids for
uses other than in space launch vehicles, rockets, missiles, associated static test apparatus, and
AE.

C9.5.2. Concept

C9.5.2.1. These QD Standards were developed on the premise that the controlling DoD
Component shall ensure that the materials of construction are compatible with the energetic
liquids, facilities are of appropriate design, fire protection and drainage control techniques are
employed, and other specialized controls (e.g., nitrogen padding, blanketing, and tank cooling)
are used, when required.

C9.5.2.2. When additional hazards associated with AE are involved, the safety distances
prescribed in other sections of this Standard shall be applied, as required.

C9.5.2.3. These Standards are based upon the estimated credible damage resulting from
an incident, without considering probabilities or frequency of occurrence.

C9.5.3. Determination of energetic liquids quantity

C9.5.3.1. The total quantity of energetic liquids in a tank, drum, cylinder, or other
container shall be the net weight of the energetic liquids contained therein. Quantity of energetic
liquids in the associated piping must be included to the points that positive means are provided
for interrupting the flow through the pipe, or interrupting a reaction in the pipe in the event of an
incident.

C9.5.3.2. When the quantities of energetic liquids are given in gallons [liters], the
conversion factors given in Table C9.T17. may be used to determine the quantity in pounds [kg].

C9.5.4. Measurement of separation distances

C9.5.4.1. Measure from the closest controlling hazard source (e.g., containers, buildings,
segment, or positive cutoff point in piping).

147 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.5.4.2. Measure from the nearest container or controlling subdivision, when buildings
containing a small number of cylinders or drums are present or when quantities of energetic
liquids are subdivided effectively.

Notes for Table C9.T16.:

1. Flammable or combustible liquid classification index based on flash point and boiling point versus criteria as
specified in 29 CFR 1910.106 Occupational Safety and Health Standards (Reference (r)) and NFPA 30
Flammable and Combustible Liquids Code (Reference (s)). Primary descriptor is a Roman numeral, possibly
with an additional letter.
2. NFPA oxidizer classification index as described in NFPA 430 Code for the Storage of Liquid and Solid
Oxidizers (Reference (t)). Descriptor is an ordinary number.
3. Positive measures for spill containment/control shall be taken for isolated storage of energetic liquids IAW
applicable Occupational Safety and Health Administration (OSHA) and NFPA guidance (referenced in Tables

148 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

fragment distances are specified, applicable OSHA and/or NFPA guidance referenced in Tables C9.T19. and
C9.T20., respectively, should also be used.
4. Hydrogen peroxide solutions of concentration greater than 91 percent are NFPA Class 4 oxidizers.
5. Should be used as a default value, unless otherwise hazard classified, when the material is packaged in small
(non-bulk) shipping containers, portable ground support equipment, small aerospace flight vehicle propellant
tanks, or similar pressure vessels that provide heavy confinement (burst pressure greater than 100 psi [690
kPa]).
6. Should be used as a default value, unless otherwise hazard classified, when the material is packaged in small
(non-bulk) shipping containers (DoT 5C or equivalent), portable ground support equipment, small aerospace
flight vehicle propellant tanks, or similar pressure vessels providing a lower level of confinement (burst
pressure less than or equal to 100 psi [690 kPa]) and if adequate protection from fragments is not provided from
terrain, effective barricades, nets, or other physical means (lightweight building construction is not adequate).
If protection from fragments is provided, use the IBD/PTRD “Protected” column of Table C9.T22.
7. For large ready, bulk, or rest storage tanks (as defined in subparagraphs C9.5.5.7., C9.5.5.9., and C9.5.5.10.),
use Table C9.T22.
8. Where there is a reasonable risk of vapor cloud explosion of large quantities (for example, in bulk tank storage).
9. Technical grade nitromethane in unit quantities of 55 gallons [208.2 liters] or less in DoT-approved containers
listed in 49 CFR 173.202 (Reference (e)) may be stored as flammable liquids (Table C9.T19.) provided the
following apply:
a. Packages are stored only one tier high.
b. Packages are protected from direct rays of the sun.
c. Maximum storage life of 2 years, unless storage life tests indicate product continues
to meet purchase specification. Such tests are to be repeated at 1-year intervals thereafter.
10. For underwater static test stands, when operated at hydrostatic pressure above 50 psig [345 kPa], or for
propellant tanks or other vessels having burst pressures of greater than 100 psig [690 kPa] without acceptable
pressure relief devices (unless otherwise hazard classified). For underwater test stands, the TNT equivalence
(i.e., MCE) should include the total energetic liquids weight in all pumps and plumbing, as well as the weight of
energetic liquids held in tankage (under the test cell hydrostatic pressure) unless acceptable mitigation measures
such as fuel line detonation arrestors and/or fuel tank isolation/barricading are used (as determined by hazard
analysis).
11. Should be used as a default value, unless otherwise hazard classified, when the material is packaged in small
vehicle propellant tanks, small (non-bulk) shipping containers, portable ground support equipment, or similar
pressure vessels that provide relatively heavy confinement (burst pressure between 50 – 100 psig [345 – 690
kPa]) without acceptable pressure relief devices.
12. NG is Nitroglycerin, TMETN is Trimethylolethane Trinitrate, DEGDN is Diethyleneglycoldinatrate, TEGDN is
Triethylene Glycol Dinitrate, and BTTN is Butane-Trio-Trinitrate.

From gallons to lbs [liter to kg]:
lbs of energetic liquids = gallons X density of energetic liquids (lbs/gallon). [English EQN C9.T17-1]

From kg/liter to lb/gallon: 1 kg/liter = 0.11983*lb/gallon [English EQN C9.T17-4]

C9.5.5. Hazard Classification of Energetic Liquids

C9.5.5.1. The main UN hazard classification designators for energetic liquids are
indicated below. (The original liquid propellant Hazard Groups I - IV and CG A - F are no
longer used.)
C9.5.5.1.1. Class 1: Explosives.

C9.5.5.1.2. Class 2: Compressed or liquefied gases.

C9.5.5.1.3. Class 3: Flammable liquids.

C9.5.5.1.4. Class 4: Flammable solids and self-reactive materials.

C9.5.5.1.5. Class 5: Oxidizers.

C9.5.5.1.6. Class 6: Toxic/infectious substances.

C9.5.5.1.7. Class 8: Corrosive.

C9.5.5.1.8. Class 9: Miscellaneous.

C9.5.5.2. Because two energetic liquids might each be compatible with certain explosive
AE stores, but incompatible with each other, a two-part compatibility group designation is
assigned to an energetic liquid. (The design and logistics of modern weapons sometimes require
that consideration be given to permitting storage or operations involving energetic liquids in a
storage structure containing solid explosives. For example, it may be necessary to store
hydrocarbon-fueled cruise missiles having high explosive warheads with fueled configurations
not containing explosive warheads. Another example is the storage of liquid gun propellant with
explosive AE components.)

C9.5.5.2.1. The first element is the standard storage and transportation CG

designation. The alpha designations are the same as the CG designations for UN Class 1 as
given in Chapter 3. However, for storage and handling on DoD facilities, a CG may also be
assigned to an energetic liquid in a Class other than Class 1. The absence of a CG indicates
incompatibility with solid explosives.

C9.5.5.2.2. The second element is a new Energetic Liquid Compatibility Group

(ELCG) designation. The ELCG applies to mixed storage of energetic liquids or AE containing

151 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

energetic liquids. The ELCG is specified in parentheses as the last element of the hazard
classification. The ELCG designations and definitions are:

C9.5.5.2.2.1. LA: Energetic liquids that are strong oxidizers, mainly of acidic
character. These materials may cause or contribute to the combustion of other material, possibly
resulting in serious flare fires or explosions. Includes, but is not limited to, nitrogen tetroxide
and Mixed Oxides of Nitrogen (MON), Inhibited Red Fuming Nitric Acid (IRFNA), liquid
oxygen (LO2), hydrogen peroxide (H2O2), and gels, slurries, or emulsions of these chemicals.

C9.5.5.2.2.2. LB: Energetic liquids that are readily combustible when exposed
to, or ignited in the presence of an oxidizing agent, but that are not strong reducing agents. Some
may be hypergolic with group LA materials. Includes, but is not limited to, hydrocarbons such
as kerosenes and strained ring ramjet fuels; liquid hydrogen (LH2); and gels, slurries, or
emulsions of these chemicals.

C9.5.5.2.2.3. LC: Energetic liquids that are readily combustible when exposed
to, or ignited in the presence of an oxidizing agent, and are also strong reducing agents. These
will likely be hypergolic with group LA substances. Includes, but is not limited to, hydrazines
and other amines; and gels, slurries, or emulsions of these chemicals.

C9.5.5.2.2.4. LD: Energetic liquids that act mainly as combustible fuels, similar
to groups LB and LC, when exposed to or ignited in the presence of oxidizing agents but that
may act as oxidizers in some combinations. They may be a monopropellant with the right
catalyst, or may be pyrophoric and ignite upon release to the atmosphere. Examples are boranes
and ethylene and propylene oxides.

C9.5.5.2.2.5. LE: Energetic liquids having characteristics that do not permit

storage with any other energetic liquid. They may react adversely with either fuels (reducing
agents) or oxidizers. Examples are nitromethane, nitrate ester-based formulations such as Otto
Fuel II, liquid monopropellants containing Hydroxyl Ammonium Nitrate (HAN); halogen
fluorides (ClF3 and ClF5) and fluorine; and gels, slurries, or emulsions of these chemicals.

C9.5.5.2.3. For mixing of energetic liquids:

C9.5.5.2.3.1. Different energetic liquids in the same ELCG may be stored

together.

C9.5.5.2.3.2. ELCG-LE may not be mixed with other ELCG or dissimilar ELCG-
LE.

C9.5.5.2.3.3. Mixed storage is prohibited between energetic liquids of different

ELCG designations with one exception.

C9.5.5.2.3.3.1. ELCG-LB and -LC should not be stored together, particularly

when the majority of the material stored is ELCG-LB; however, mixed storage of ELCG-LB and
-LC is permitted when operationally necessary.

152 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.5.5.2.4. As an example, for the 1.3C(LE) hazard classification for HAN-based

liquid gun propellant XM-46:

C9.5.5.2.4.1. “C”: indicates the propellant can be stored in the same magazine
with CG-C solid propellants. Because CG-C and CG-D can be mixed, CG-D high explosive
projectiles could also be stored with the energetic liquid gun propellant.

C9.5.5.2.4.2. “LE”: indicates that hydrocarbon fuels (e.g., Jet Propellant (JP)-10),
which is an ELCG-LB, would not be permitted in this storage scenario, because its ELCG-LB
indicates incompatibility with ELCG-LE.

C9.5.5.3. Complete DoD hazard classification assignments for current energetic liquids
are shown in Table C9.T16. (Conversions for gallons of energetic liquids to pounds is provided
in Table C9.T17.)

C9.5.5.4. Each new energetic liquid, or new non-bulk packaging configuration of an

energetic liquid, developed by a DoD Component or adopted for DoD use, must be examined
and assigned a hazard classification per Reference (d).

C9.5.5.5. A different minimum distance may be assigned during the hazard classification
process when the hazards of a particular new packaging configuration are not adequately
addressed. This distance shall be indicated parenthetically, in hundreds of feet, as the first
element of the hazard classification. For example, if a new liquid oxidizer pressure vessel
configuration is hazard classified as (04)2.2(LA), then a minimum distance of 400 ft [122 m]
would apply for IBD and PTRD, otherwise the prescribed liquid oxidizer QD criteria would
apply.

C9.5.5.6. The predominant hazard of the individual energetic liquids can vary depending
upon the location of the energetic liquid storage and the operations involved. These locations are
listed below in the order of decreasing hazards.

C9.5.5.6.1. Launch pads. Operations at these facilities are very hazardous because of
the proximity of fuel and oxidizer to each other, the frequency of launchings, lack of restraint of
the vehicle after liftoff, and the possibility of fallback with resultant dynamic mixing on impact.
To compute the equivalent explosive weight for the launch pad, use Table C9.T18. with the
combined energetic liquids weight in the launch vehicle tanks and any energetic liquids in piping
that are subject to mixing, except as indicated in subparagraph C9.5.5.8.

C9.5.5.6.2. Static test stands. Operations at these facilities are less hazardous
because test items are restrained and subject to better control than launch vehicles. As with
launch pads, the proximity of fuel and oxidizer presents a significant hazard. To reduce this
hazard, tankage should be separated and remotely located from the static test stand. The
equivalent explosive weights of Table C9.T18. shall be used, with the combined energetic liquids
weight subject to mixing as determined by hazard analysis. The amount of energetic liquids held

153 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

in run tanks can be excluded from consideration if the test stand meets all the following criteria,
if applicable:

C9.5.5.6.2.1. All tanks are American Society of Mechanical Engineers (ASME)

certified and maintained per ASME Code, section VIII, Division 1 or Division 2 (Reference (u)).

C9.5.5.6.2.2. For cryogenic propellants, all tanks are constructed with double
wall jacketing.

C9.5.5.6.2.3. Run tankage is protected from fragments produced by an engine

malfunction.

C9.5.5.6.2.4. Both the fuel and oxidizer lines contain two (redundant), remotely-
operated valves to shut off flow in the event of a malfunction.

Notes for Table C9.T18.:

1. The percentage factors given in the table are to be used to determine equivalent explosive weights of energetic
liquids mixtures at static test stands and range launch pads when such energetic liquids are located aboveground
and are unconfined except for their tankage. Other configurations shall be considered on an individual basis to
determine equivalent explosive weights.
2. The equivalent explosive weight calculated by the use of this table shall be added to any non-nuclear explosive
weight aboard before distances can be determined from Tables C9.T1. and C9.T5.
3. These equivalent explosive weights apply also for these substitutions:
Alcohols or other hydrocarbons for RP-1.
H2O2 for LO2 (only when LO2 is in combination with RP-1 or equivalent hydrocarbon fuel).
Monomethylhydrazine (MMH) for N2H4, Unsymmetrical Dimethylhydrazine (UDMH), or combinations of the
two.
4. For quantities of energetic liquids up to but not over the equivalent explosive weight of 100 lbs [45.4 kg] of AE,
the distance shall be determined on an individual basis by the DoD Component. All personnel and facilities,
whether involved in the operation or not, shall be protected by operating procedures, equipment design,
shielding, barricading, or other suitable means.
5. Distances less than intraline are not specified. Where a number of prepackaged energetic liquid units are stored
together, separation distance to other storage facilities shall be determined on an individual basis by the DoD
Component, taking into consideration normal hazard classification procedures.
6. For siting launch vehicles and static test stands, equivalent explosive weight is the larger of:
a. The weight equal to 8W 2/3 [4.13 Q2/3] where W is the weight of LO2/LH2; or
b. 14 percent of the LO2/LH2 weight.
NOTE: For these calculations, use the total weight of LO2/LH2 present in the launch vehicle, or the total weight
in test stand run tankage and piping for which there is no positive means to prevent mixing in credible accidents.
When it can be reliably demonstrated that the MCE involves a lesser quantity of energetic liquids subject to
involvement in a single reaction, the lesser quantity may be used in determining the equivalent explosive weight.
When siting is based on a quantity less than the total energetic liquids present, the MCE and associated explosive
yield analysis must be documented in an approved site plan (section C5.4.).
7. These are hypergolic combinations.

155 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

8. The equivalent explosive weight of the hybrid rocket system N2O4 liquid oxidizer combined with PBAN solid
fuel was evaluated as 15 percent for an explosive donor accident scenario, 5 percent for a high-velocity impact
scenario, and less than 0.01 percent (negligible) for static mixing (tower drop) failures (Air Force Rocket
Propulsion Laboratory AFRPL-TR-67-124 (Reference (v))).
9. See Note 10 of Table C9.T16.
10. See Note 8 of Table C9.T16.

C9.5.5.7. Ready storage is relatively close to the launch and static test stands; normally it
is not involved directly in feeding the engine as in the case with run tankage, which is an integral
part of all launch and test stand operations. The equivalent explosive weights of Table C9.T18.
shall be used with the combined energetic liquids weight subject to mixing if the facility design
does not guarantee against fuel and oxidizer mixing and against detonation propagation to, or
initiation at, the ready storage facility when an accident occurs at the test stand, on the ground at
the launch pad, or at the ready storage areas. Otherwise, fire and fragment hazards shall govern
(Tables C9.T16., C9.T19., C9.T20., C9.T21., and C9.T22.).

C9.5.5.8. Fire and fragment hazards govern (Tables C9.T16., C9.T19., C9.T20.,
C9.T21., and C9.T22.) if the design is such that the system is closed except for approved
venting; is completely airtight; fuel and oxidizer never are employed concurrently; and each has
a completely separate isolated system and fitting types to preclude intermixing, and the energetic
liquids are of required purity. Otherwise, equivalent explosive weights (Table C9.T18.) shall be
used with the combined energetic liquids weight.

C9.5.5.9. Bulk storage is the most remote storage with respect to launch and test
operations. It consists of the area, tanks, and other containers therein, used to hold energetic
liquids for supplying ready storage and, indirectly, run tankage where no ready storage is
available. Fire and fragment hazards govern (Tables C9.T16., C9.T19., C9.T20., C9.T21., and
C9.T22.) except in special cases as indicated in Tables C9.T16. and C9.T18.

C9.5.5.10. Rest storage is temporary-type storage and most closely resembles bulk
storage. It is a temporary parking location for barges, trailers, tank cars, and portable hold tanks
used for topping operations when these units actually are not engaged in the operation, and for
such vehicles when they are unable to empty their cargo promptly into the intended storage
container. Fire and fragment hazards govern (Tables C9.T16., C9.T19., C9.T20., C9.T21., and
C9.T22.) except in special cases as indicated in Tables C9.T16. and C9.T18. The transporter
becomes a part of that storage to which it is connected during energetic liquids transfer.

1. Other guidelines for diking, tank or container construction, tank venting, and facility construction apply (except
for Class III B combustible liquids, e.g. Otto Fuel II). Refer to Reference (r) and Reference (s) for further
guidance on liquid storage and fire protection.
2. Refer to Reference (r) and Reference (s) for definition and explanation of OSHA/NFPA classification of
flammable and combustible liquids.
3. Guidelines on interior storage configuration (for container storage inside buildings) also apply with these
exceptions:
a. If the storage building is located at least 100 ft [30.5 m] from any exposed building (under the direct
jurisdiction of a fire protection organization) or property line; or
b. If the storage building is located at least 200 ft [61 m] from any exposed building (not under the direct
jurisdiction of a fire protection organization) or property line; or
c. For combustible liquids that will not exhibit sustained burning in bulk form, e.g. Otto Fuel II, as determined
through American Society for Testing and Materials (ASTM) D 92 Standard Test Method for Flash and Fire
Points by Cleveland Open Cup or comparable testing. Refer to Reference (r) and Reference (s) for further
guidance on liquid storage and fire protection.
4. For container storage inside of a building, IBD/PTR distances may be less than 50 ft [15.2 m] (to a minimum of
10 ft [3.05 m]) if the storage building is constructed of fire-resistive exterior walls having an NFPA fire
resistance rating of 2 hours or more, according to NFPA 251 Standard Methods of Tests of Endurance of
Building Construction Materials (Reference (w)).
5. For large tank storage, QD may be 25 ft [7.6 m] for tank capacities up to 100,000 gallons [378,541 liters], and
37.5 ft [11.4 m] for capacities between 100,001 gallons [378,545 liters] and 500,000 gallons [1,892,706 liters].
6. For flammable liquids container storage inside of a building, ILD/aboveground IMD is 50 ft [15.2 m] (except as
in Note 4), or for adjacent incompatible oxidizer storage, distances specified for energetic liquid oxidizers
(Table C9.T20.) or oxygen (Table C9.T21.). For flammable liquids storage in fixed or large portable tanks,
ILD/aboveground IMD is either (1) for compatible energetic liquids, equal to one-sixth of the sum of the
diameters of the two adjacent tanks, or distances specified in Note 5 for adjacent container storage inside of a
building; or (2) for adjacent incompatible oxidizer storage, distances specified for energetic liquid oxidizers
(Table C9.T20.) or oxygen (C9.T21.). ECM may be used to their physical capacity for storing flammable
energetic liquids provided they comply with the construction and siting requirements of Chapters 5 and 9,
respectively for HD 1.1. ECM must be sited for a minimum of 100 lbs [45.4 kg] of HD 1.1 items using Tables
C9.T4. and C9.T6.

Notes for Table C9.T22.:

1. Positive measures shall be taken to prevent mixing of hydrogen or hydrazines and adjacent oxidizers in the
event of a leak or spill.

6. ILD/aboveground IMD distances in this column apply for adjacent compatible (ELCG LB or LC) storage; for
adjacent incompatible (other ELCG) storage, use IBD distances shown in previous columns. ECM may be used
to their physical capacity for storing hydrogen provided they comply with the construction and siting
requirements of Chapters 5 and 9, respectively for HD 1.1. ECM must be sited for a minimum of 100 lbs [45.4
kg] of HD 1.1 items using Tables C9.T4. and C9.T6.
7. Distances are 37.5 percent of “protected” column.
8. Extrapolations above 1,000,000 lbs [453,590 kg] extend well outside data included in Reference (y) from which
the original QD tables were derived; however, they are supported by independent calculations and knowledge of
like phenomena.

C9.5.5.11. Run tankage (operating tankage) consists of the tank and other containers and
associated piping used to hold the energetic liquids for direct feeding into the engine or device
during operation. The contents of properly separated “run tanks” (operating tankage) and piping
are normally considered on the basis of the pertinent hazards for the materials involved, except
for quantities of incompatible materials that are or can be in a position to become mixed.
Equivalent explosive weights shall be used (Table C9.T18.) for quantities of such materials
subject to mixing unless provisions of subparagraphs C9.5.5.6.2.1. through C9.5.5.6.2.4. are
satisfied.

C9.5.5.12. A 25-ft [7.6 m] clear zone to inhabited buildings shall be maintained, as a

minimum, on each side of pipelines used for energetic liquids (excluding flammable or
combustible liquids that exhibit normal fire hazards such as RP-1, JP-10, and Otto Fuel II).
Tables C9.T16., C9.T20., C9.T21., and C9.T22. apply, as appropriate.

C9.5.6. QD standards. Since many energetic liquids are not classified as UN Class 1
explosives, conventional QD storage criteria do not generally apply to these materials. At the

163 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

same time, the (non-Class 1) UN transportation hazard classifications for many energetic liquids
appear to be inappropriate and/or inadequate for application to storage safety (based on available
accident and test data). For example, hydrazine has a UN hazard classification of 8 (corrosive),
while it also is subject to dangerous fire and explosive behavior. Thus, the implementation of
QD criteria for energetic liquids is based on an independent determination of the predominant
hazard presented by the material in the storage environment. The following standards are
applicable to energetic liquids used for propulsion or operation of missiles, rockets, and other
related devices.

C9.5.6.1. Tables C9.T16., C9.T19., C9.T20., C9.T21., and C9.T22. provide minimum
distance requirements for storage of bulk quantities, and in some cases, pressure vessels and
other commercial packagings of energetic liquids. In general, the minimum distance required by
the material requiring the greatest distance shall separate storage of different energetic liquids.
In addition, positive measures shall be taken to control the flow of energetic liquids in the event
of a leak or spill, in order to prevent possible fire propagation or accumulation of flammable
liquids near other storage, and/or to prevent mixing of incompatible energetic liquids (except for
specific hazardous locations as identified in subparagraph C9.5.5.6. above). Equivalent
explosive weights apply for some materials as indicated in Tables C9.T16. and C9.T18.
Fragment hazards govern for some materials in certain packaging configurations. For the more
conventional fuels and oxidizers, and also where minimum blast and/or fragment criteria are not
required due to low confinement packaging, QD standards are adopted from OSHA and NFPA
guidelines to account for normal fire protection principles.

C9.5.6.2. For specific hazardous locations as defined in subparagraph C9.5.5.6. above,

equivalent explosive weights may apply. If so, consult Tables C9.T16. and C9.T18. with the
combined energetic liquids weight subject to mixing and use distances found in Table C9.T1. or
C9.T5. Enter the equivalent explosive weight in Table C9.T1. or C9.T5. QD standards for other
conditions and equivalent explosive weights for any combination not contained in Table C9.T16.
or C9.T18. shall be determined by the controlling DoD Component.

C9.5.7. Contaminated energetic liquids

C9.5.7.1. Caution shall be exercised in the storage and handling of contaminated

energetic liquids. Such contamination may increase the degree of hazard associated with the
energetic liquids.

C9.5.7.2. Energetic liquids known to be contaminated or in a suspect condition shall be

isolated and provided separate storage from all other energetic liquids pending laboratory
analysis for verification of contamination and disposition requirements, if any.

C9.6. SITING

C9.6.1. Airfields and Heliports.

C9.6.1.1. Scope and Application.

Notes for Table C9.T24.:

1. Use applicable IBD.
2. Use applicable PTRD.
3. For HD 1.1, use applicable IMD. For HD 1.2, apply Note 10. Protects against simultaneous detonation of AE
on adjacent aircraft, but does not prevent serious damage to aircraft and possible propagation of detonation due
to fragments, debris, or fire.
4. Use applicable ILD.
5. Use Table C9.T23. distances for mass-detonating items and applicable PTRD for nonmass-detonating items.

168 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

6. Use Table C9.T23. distances for DoD Component aircraft parking areas and applicable IBD for non-DoD entity
aircraft parking areas.
7. Use applicable PTRD for locations in the open where passengers enplane and deplane; use applicable IBD if a
structure is included where passengers assemble, such as a passenger terminal building.
8. No distance required to recreational areas that are used exclusively for alert personnel manning the
combat-loaded aircraft. Other recreational areas where people are in the open shall be at applicable PTRD.
When structures, including bleacher stands, are a part of such area, applicable IBD shall be used.
9. Recreational areas, where people are in the open, shall be at applicable PTRD. When structures, including
bleacher stands are part of such area, applicable IBD shall be used.
10. Within these areas of airfields and heliports exclusively used by the DoD Components, the separation of aircraft
parking areas from combat aircraft parking areas and their ready AE storage facilities and AE cargo areas are
considered to be a command function. At joint DoD/non-DoD use airfields and heliports, the combat aircraft
parking areas and its ready AE storage facilities and AE cargo area shall be separated from non-DoD aircraft as
specified in Note 6, above.
11. Use 18W1/3 [7.14Q1/3] distances from side or rear of ECM to taxiways; use PTRD from front of ECM or any
other storage locations to taxiways; and use PTRD from all storage location to runways.

C9.6.1.5. Hardened Aircraft Shelters (HAS).

C9.6.1.5.1. HAS and associated AE facilities shall be separated according to Table

C9.T25. At these distances there will be a high degree of protection against propagation of
explosion when HAS doors are properly secured. However, the exposed shelter may be
damaged heavily and aircraft and AE therein may be rendered unserviceable.

C9.6.1.5.2. HAS and associated AE facilities separated according to Table C9.T26.

will provide a higher degree of asset preservation than those provided in Table C9.T25. An
explosion in one shelter or ready storage facility may destroy it and its contents, but aircraft
within adjacent shelters will be undamaged provided the doors are closed. These aircraft may
not be immediately accessible due to debris.

C9.6.1.5.3. The front, side, or rear sectors of a HAS as either a PES or an ES are
defined in Figure C9.F9.

C9.6.1.5.4. For a third-generation HAS containing up to 11,000 lbs [4,989.5 kg]

NEWQD, use separation distances of Table C9.T27. to unhardened ES. The QD criteria given in
Table C9.T27. apply to all HD 1.1 AE, regardless of any minimum fragment distance denoted by
(xx) 1.1.

C9.6.1.5.5. When operational necessity dictates, as determined by the DoD

Component, separation distances less than those contained in Tables C9.T25. and C9.T26. may
be approved; however, it must be shown that equivalent protection is being provided.

172 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

Notes for Table C9.T27.:

1. Separation distances are based on shelter doors remaining closed, except for aircraft towing, fueling, servicing,
run-up, or taxiing, and during integrated combat turnarounds or short periods when maintenance equipment or
munitions are being moved into or out of the shelter. Where doors are left open for extended periods, normal
combat aircraft parking area criteria of Table C9.T24. apply.
2. Separate AE from the HAS walls by a distance sufficient to prevent breaching. For less than 1,100 lbs [498.9
kg] NEWQD a 3-ft [0.91 m] separation from the wall is sufficient.
3. These QD criteria apply to IBD, PTRD, and ILD exposures for quantities < 1,100 lbs [498.9 kg] NEWQD.
4. For quantities > 1,100 to 11,000 lbs [498.9 to 4,989.5 kg] NEWQD, these QD only apply to IBD exposures. Use
50 percent of the IBD criteria for PTRD exposures with a 300 ft [91.4 m] minimum distance (out the front or
rear) or a 394 ft [120.1 m] minimum distance (off the sides). Use 35 percent of the IBD criteria for intraline
exposures with a 300-ft [91.4 m] minimum distance (out the front and rear) or a 394-ft [120.1 m] minimum
distance (off the sides).

C9.6.1.6. Combat Aircraft Support Facilities. See subparagraph C9.4.1.1.2.1.11. for

separation distance criteria associated with such facilities. When operational necessity dictates,
separation distances less than K18 [7.14] may be approved; however, it must be demonstrated
that K18 [7.14] equivalent protection is provided.

C9.6.1.7. AE Prohibited Areas. Areas immediately beyond the ends of runways and
along primary flight paths are subject to more aircraft accidents than other areas. For this reason,
AE is prohibited from Accident Potential Zones (APZ) I and II and Clear Zones (CZ) of all
aircraft landing facilities, as designated and described in detail in DoD Component airfield and
airspace criteria directives.

C9.6.2. Pier And Wharf Facilities

C9.6.2.1. Scope and Application. QD herein are for HD 1.1 AE. If only AE of other HD
are involved, the applicable QD shall be applied. This section:

C9.6.2.1.1. Applies to:

C9.6.2.1.1.1. Ship and barge units, hereafter referred to as ships.

C9.6.2.1.1.2. Piers and wharf and associated facilities at which AE may be

handled, or be present in ships’ holds or conveyances.

C9.6.2.1.1.3. Loading, off-loading, stowing, and shifting of AE from ships’

magazines.

C9.6.2.1.2. Does not apply (i.e., no QD required) to:

C9.6.2.1.2.1. AE in static storage in ships’ magazines and intended for the

service of shipboard armament or aircraft, provided the Service Secretary formally accepts any
explosives risk associated with such storage.

C9.6.2.1.2.2. Handling < 300 lbs [136.1 kg] NEWof combined HD 1.3 and HD
1.4 AE that are necessary for ship’s security and safety at sea.

173 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.2.2. Determining the Quantity of Explosives in a Ship

C9.6.2.2.1. The NEWQD on board a ship shall be determined per section C9.2.

C9.6.2.2.2. When ships are separated by 11W1/3 [4.36Q1/3] distances or greater, QD

shall be based individually on the quantity of each ship. Lesser separation distances require that
the AE in all ships be totaled.

C9.6.2.3. Measurement of Separation Distances

C9.6.2.3.1. Moored Ships

C9.6.2.3.1.1. Measurement of separation distances between ships or barges shall

be from the nearest point of one ship’s magazine (i.e., the PES) or the barge:

C9.6.2.3.1.1.1. For IMD: To the nearest point of another ship’s magazine or

a barge.

C9.6.2. 3.1.1.2. For IBD and PTRD: To the nearest point of another ship or a
barge.

C9.6.2.3.1.2. Measurement of separation distances between ships or barges and

shore ES shall be from the nearest point of a ship’s magazine or the barge to the nearest point of
the ES.

C9.6.2.3.2. Pier Operations. Measurement of separation distances from piers to

surrounding facilities shall be from the nearest point that AE will be handled to the nearest point
of an ES. (NOTE: Movement of railcars or trucks passing through the clear space between ships
at a pier or between piers is considered as an operational risk. It is generally impracticable to
separate berths at a single pier by enough distance to prevent mass detonation of HD 1.1. To the
extent operationally feasible, the number of such exposures and total time required should be
reduced to the maximum extent practicable through scheduling.)

C9.6.2.3.3. Anchorages. Measurements from anchorages generally shall be from the

boundary of the area designated for the explosives anchorage. The explosives anchorage for a
single ship is a circle, the radius of which is the distance from the mooring buoy or a ship’s
anchor to the stern of the ship or of the AE lighters alongside when riding to the full scope of the
chain. For an explosives anchorage, the separation distance to an ES will depend upon whether
any ships are separated properly (see subparagraph C9.6.2.2.2.).

C9.6.3. Siting Criteria and Application of QD

C9.6.3.1. Maritime Prepositioning Ships (MPS)

174 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.3.1.1. Reduced QD criteria may be applied to those MPS that contain up to

1,300,000 lbs [589,667 kg] NEWQD of AE stored in standard International Standardization
Organization (ISO) shipping containers.

C9.6.3.1.2. IBD and PTRD for MPS can be determined using K = 40.85 [16.21] with
a 3,700-ft [1,128 m] minimum fragment distance for IBD and K = 24.01 [9.52] with a 2,220-ft
[677 m] minimum fragment distance for PTRD for MPS loads where no more than 52 percent of
the NEWQD is HD 1.1. When the percentage of HD 1.1 is:

C9.6.3.1.2.1. Between 52 and 65 percent, use the IBD and PTRD columns of
Table C9.T28.

C9.6.3.1.2.2. Above 65 percent, use the Other PES columns of Table C9.T1. with
a 3,700-ft [1,128 m] minimum fragment distance for IBD and a 2,220-ft [677 m] minimum
fragment distance for PTRD.

C9.6.3.1.3. The QD between applicable MPS piers/anchorages and non-explosives

loading piers/anchorages can be determined using K = 32 [12.69] with a 3,500 ft [1,067 m]
minimum fragment distance for MPS loads, where no more than 52 percent of the total NEWQD
is HD 1.1. (An exception for non-explosives MPS is provided in subparagraph C9.6.3.8.1.)
When the percentage of HD 1.1 is:

C9.6.3.1.3.1. Between 52 and 65 percent, use the Ship-to-Ship column in Table

C9.T28.

C9.6.3.1.3.2. Above 65 percent, use K = 40 [15.87] with a minimum fragment

distance of 3,500 ft [1,067 m].

C9.6.3.2. Scuttling Site. A properly located scuttling site will, when feasible, be
provided for positioning a ship for its flooding or sinking in the event it catches fire and must be
moved to avert damage to other ships or piers. The location of a scuttling site shall depend on
the greatest NEWQD that may be in a single ship at any one time. (Table C9.T1. provides the
applicable QD.) Additional considerations for the scuttling site include:

C9.6.3.2.1. The site should have sufficient maneuvering room and depth to permit
sinking the largest vessel that may be handled at the installation so that the holds will be flooded
completely at low tide.

C9.6.3.2.2. The scuttling site should provide the best available protection to other
ships, piers, and shore installations in the event of a mass explosion.

DoD 6055.09-STD, February 29, 2008

C9.6.3.3. Explosives Anchorage. Explosives anchorage shall be separated from the main
ship channel and from normally traversed routes of ships entering or leaving the harbor by the
distances indicated below. (Occasional watercraft passing through the arcs, while outside both
the main ship channel and normally traversed routes of ships entering and leaving the harbor, are
not subject to QD requirements.)

C9.6.3.3.1. The PTRD from “Other PES” column of Table C9.T1. and

C9.6.3.3.2. The turning circles and stopping distances of other ships passing the
anchorage but not less than 3,000 ft [914.4 m].

C9.6.3.3.3. Separation of Ships at Explosives Anchorages. When explosives

anchorages are used for both loading and unloading ships and for mooring loaded ships, they
shall be separated as follows:

C9.6.3.3.3.1. Loaded ships shall be separated one from another by 18W1/3

[7.14Q1/3].

C9.6.3.3.3.2. Loading and unloading ships shall be separated one from another by
11W1/3 [4.36Q1/3] and, when possible, by 18W1/3 [7.14Q1/3].

C9.6.3.3.3.3. Loaded ships shall be separated from ships loading and unloading
1/3
by 40W [15.87Q1/3].

C9.6.3.3.4. Separation of Explosives Anchorages from Explosives Piers. Explosives

anchorages shall be separated from explosives piers by 40W1/3 [15.87Q1/3], except when the
anchorage is used only for the loading or unloading of ships. In that case, 18W1/3 [7.14Q1/3] may
be used.

C9.6.3.4. Separation Distances of Ships at the Same Pier

C9.6.3.4.1. Berthing of two ships in tandem helps decrease the fragment hazard to
the AE cargo of the second ship because of the additional protection afforded by the bow or
stern.

C9.6.3.4.2. When two ships, which cannot be separated by 11W1/3 [4.36Q1/3], are
being loaded through all hatches at the same time, the spotting of railcars or trucks and the
loading of hatches in both ships should be planned in a manner that puts the greatest possible
distance both between the open hatches, and the trucks and railcars serving the two ships. When
possible, the loading of the ships shall be staggered.

C9.6.3.5. Separation of Wharf Yard from the Pier. A wharf yard shall be separated from
the pier, which it serves by 11W1/3 [4.36Q1/3] to prevent propagation. If this separation distance
cannot be met, then the wharf yard shall be considered as part of the ship or barge and added to it
for computation of the total amount of explosives for QD purposes.

177 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.3.6. Separation of Explosives Ships from Other Ships. Explosives ships being
loaded or unloaded shall be separated from non-explosives carrying ships and from loaded
explosives ships that are not underway by 40W1/3 [15.87Q1/3] distances. The PTRD from “Other
PES” column of Table C9.T1. shall be used for protection of ships that are underway.

C9.6.3.7. Barge Piers. Piers and wharfs used exclusively for loading or unloading AE on
barges or utility craft may be sited from other shore facilities as loading docks, IAW paragraph
C9.8.8. Shore facilities shall be sited under the same criteria as pier and wharf facilities, in
relation to barge piers.

C9.6.3.8. Separation of Preposition Program Ships at Anchorages. The Military Sealift

Command’s Prepositioning Program (i.e. Combat Prepositioning Force, Maritime Prepositioning
Force, Logistics Prepositioning Ships) operates both explosives-loaded and non-explosives
carrying ships that are then deployed to key locations around the world. These ships are pre-
loaded with military equipment and supplies necessary to support military forces on a short-
notice basis and thus support a common mission. The following criteria apply to Prepositioning
Program ships at anchorage:

C9.6.3.8.1. Non-explosives carrying ships shall be separated from explosives-loaded

ships by a minimum of 18W1/3 [7.14Q1/3].

C9.6.3.8.2. Non-explosives carrying ships shall be separated from non-

Prepositioning Program explosives-loaded ships by 40W1/3 [15.87Q1/3].

C9.6.3.8.3. Non-explosives carrying ships not associated with the Prepositioning

Program shall be separated from all explosives carrying ships by 40W1/3 [15.87Q1/3].

C9.6.3.8.4. All non-explosives carrying ships shall be separated from explosives

ships being loaded or unloaded by 40W1/3 [15.87Q1/3].

C9.6.4. QD Tables

C9.6.4.1. Figure C9.F10. illustrates required hazard factors. Table C9.T7B. provides the
corresponding separation distances.

C9.6.4.2. Table C9.T1. separation distances shall be maintained between explosives pier
and wharf facilities and other ES (e.g., administration and industrial areas, terminal boundaries,
main ship channels, and PTRD).

C9.6.4.3. As an ES, ships must be separated from AE operating and storage facilities
(including holding yards) by the “Other PES IBD” column of Table C9.T1.

C9.6.4.4. As a PES, ships must be separated from AE operating facilities by either the
barricaded IMD (K6 [2.38]) or unbarricaded IMD (K11 [4.36]) of Table C9.T5., as applicable.
An exception (see subparagraph C9.4.1.1.2.1.10.) is permitted when the ES is a container

178 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

stuffing and unstuffing operation that routinely supports AE ship loading and unloading
operations. (QD requirements of subparagraph C9.6.4.3. shall apply from such container
stuffing and unstuffing operations (as a PES) to an AE ship (as an ES).)

C9.6.5. General Cargo and Vehicles at AE Terminals

C9.6.5.1. Concurrent movements of mission-related general cargo, vehicles, and AE

through a terminal may be conducted for the purpose of loading or unloading the same ship.

C9.6.5.2. Concurrent operations involving other ships shall be conducted at applicable

QD separations. (See Figure C9.F10.)

C9.6.5.3. Separation of inert materials and equipment in holding areas shall be consistent
with paragraph C9.8.5.

C9.6.5.3.1. Personnel entering inert holding areas that are located within ESQD shall
be limited both in number and time of exposure.

C9.6.5.3.2. Any labor intense activity shall take place at IBD or PTRD, as applicable.

DoD 6055.09-STD, February 29, 2008

C9.7. UNDERGROUND STORAGE OF AE

C9.7.1. General

C9.7.1.1. This section provides QD standards for underground storage (e.g., natural
caverns and below grade, excavated chambers) and storage facilities providing the overpressure
confinement effects typically encountered in underground storage.

C9.7.1.2. These criteria are only applicable when the minimum distance from the
perimeter of a storage chamber to an exterior surface exceeds 0.25W1/3 [0.10Q 1/3]. (This
minimum distance normally, but not always, equals the thickness of the earth cover.)

C9.7.1.3. Use aboveground siting criteria when minimum distance criteria of

subparagraph C9.7.1.2. cannot be met.

C9.7.1.4. This section addresses explosives safety criteria both with and without rupture
of the earth cover.

C9.7.1.5. QD siting requirements of this section may be determined from the applicable
equations or by interpolating between the table and figure entries.

C9.7.1.6. Expected ground shock, debris, and airblast hazards from an accidental
explosion in an underground storage facility depend on several variables, including the local
geology and site-specific parameters. These parameters vary significantly from facility to
facility. Siting distances other than those listed may be used when validated by approved
experimental or analytical results showing equivalent protection to that required.

C9.7.2. External QD Determinations

C9.7.2.1. QD Dependence on HD. (See section C9.2. to determine the explosive weight
for mixed HD.)

C9.7.2.1.1. HD 1.1. Distances shall be determined from the total quantity of HD 1.1
in the individual chambers, unless the total quantity is subdivided to prevent rapid
communication of an incident from one subdivision to another. Connected chambers containing
HD 1.1 shall be treated as a single chamber site, unless explosion communication is prevented by
adequate subdivision or chamber separation.

C9.7.2.1.2. HD 1.2. Except for primary fragments from openings to underground

storage, external explosives safety hazards are not normally significant for HD 1.2. The safe
distance for both IBD and PTR is the IBD distance in Tables C9.T8. through C9.T12. for
locations within 10 degrees to either side of the centerline of a tunnel opening. These criteria
apply only to those detonations that occur where a line-of-sight path exists from the detonation
point to any portion of the tunnel opening. For detonations that do not have a line-of-sight path
to the tunnel opening, or where the line-of-sight path is intercepted by a barricade beyond the
opening, the IBD and PTR hazard distances are zero.

181 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.7.2.1.3. HD 1.3. HD 1.3 shall be treated as HD 1.1 with an explosive equivalence

of 100 percent for QD purposes. Any significant and validated differences in energy release per
unit mass of HD 1.3 from that of TNT may be considered.

C9.7.2.1.4. HD 1.4. External explosives safety hazards are not normally significant
for HD 1.4. Accordingly, external QD criteria do not apply for HD 1.4.

C9.7.2.1.5. HD 1.5. HD 1.5 shall be treated as HD 1.1 with an explosive equivalence

of 100 percent for QD purposes.

C9.7.2.1.6. HD 1.6. HD 1.6 shall be treated as HD 1.2.

C9.7.2.2. QD Reference Points

C9.7.2.2.1. Distances determined by blast or debris exiting from tunnel openings is

the minimum distance measured from the openings to the nearest wall or point of the location to
be protected. Use extended centerlines of the openings as reference lines for directional effects.

C9.7.2.2.2. Distances determined for airblast and debris produced by breaching of

the chamber cover shall be the minimum distance from an exterior point defined by chamber
cover thickness, on the ground surface above the storage chamber to the nearest wall or point of
the location to be protected. For configurations where the storage chambers are not distinct from
the access tunnel, the distance is the shortest distance from the tunnel roof directly above the
charge to the surface.

C9.7.2.2.3. Distances determined for ground shock shall be the minimum distance
measured from the nearest wall of the storage chamber to the location to be protected.

C9.7.2.3. IBD. IBD for HD 1.1 shall be the largest of those distances required for
protection against ground shock, debris, and airblast as defined below.

C9.7.2.3.1. Ground Shock

C9.7.2.3.1.1. For protection of residential buildings against significant structural

damage by ground shock, the maximum particle velocity induced in the ground at the building
site shall not exceed:

C9.7.2.3.1.1.1. 2.4 ips [6.1 cm/s] in soil.

C9.7.2.3.1.1.2. 4.5 ips [11.4 cm/s] in weak rock.

C9.7.2.3.1.1.3. 9.0 ips [22.9 cm/s] in strong rock.

182 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.7.2.3.1.2. The above values form the basis for the following equations
(NOTE: Dig is in ft and W is the explosive quantity in lb [Dig is in m and Q is the explosive
quantity in kg].):

C9.7.2.3.1.2.1. For sitings in moderately strong to strong rock with chamber

loading densities [NEWQD/chamber internal volume] of 3.0 lb/ft3 [48.1 kg/m3] or less, the IBD
for ground shock, Dig is:

Dig = 5.8W1/3 [English EQN C9.7-1]

Dig = 2.30Q1/3 [Metric EQN C9.7-2]

C9.7.2.3.1.2.2. For higher loading densities in chambers sited in moderately

strong to strong rock, and for all loading densities in other materials, the IBD for ground shock
(See C9.7.2.3.1.2.3. for values of decoupling factor, fg.) is:

Dig = 12.5fgW4/9 (Moderately strong to strong rock) [English EQN C9.7-3]

Dig = 5.41fgQ4/9 (Moderately strong to strong rock) [Metric EQN C9.7-4]
Dig = 11.1fgW4/9 (Weak rock) [English EQN C9.7-5]
Dig = 4.81fgQ4/9 (Weak rock) [Metric EQN C9.7-6]
Dig = 2.1fgW4/9 (Soil) [English EQN C9.7-7]
Dig = 0.91fgQ4/9 (Soil) [Metric EQN C9.7-8]

C9.7.2.3.1.2.3. The dimensionless, decoupling factor, fg, depends on chamber

loading density, w (lb/ft3 [kg/m3]), and is (Values of Dig and Dig/fg are given in Table C9.T29.
Values of fg are shown in Table C9.T30. Alternate values for Dig may be used only when
justified by site-specific ground shock data.):

fg = 0.267w0.3 [English EQN C9.7-9]

fg = 0.11604w0.3 [Metric EQN C9.7-10]

C9.7.2.3.2. Debris. (See paragraph C5.2.3. for special design considerations.)

C9.7.2.3.2.1. A minimum IBD distance of 1,800 ft [548.6 m] for debris throw

from an opening shall apply within 10 degrees to either side of the centerline axis of that
opening, unless positive means are used to prevent or control the debris throw.

C9.7.2.3.2.2. The distance Did that is required for protection of inhabited areas
against the effects of debris thrown from breaching of the cover material over a detonation
depends on the thickness of the cover (C) over the storage chamber. The critical cover thickness,
Cc , is defined as 2.5W1/3 [1.0Q1/3].

C9.7.2.3.2.2.1. When Cc > 2.5W1/3 [1.0Q1/3], debris from a surface breach

need not be considered.

C9.7.2.3.2.2.2. When Cc < 2.5W1/3 [1.0Q1/3], then the debris distance, Did
shall be calculated using the equation:

183 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

Did = fd*fc*W0.41 [English EQN C9.7-11]

Did = fd*fc*Q0.41 [Metric EQN C9.7-12]

C9.7.2.3.2.2.3. The dimensionless, decoupling factor, fd depends on chamber

loading density, w (lb/ft3 [kg/m3]), and is:
fd = 0.6w0.18 [English EQN C9.7-13]
fd = 0.3615 w0.18 [Metric EQN C9.7-14]

C9.7.2.3.2.2.4. Values of fd are shown in Table C9.T30. The coupling factor

fc is related to the type of rock around the storage chamber and the scaled cover thickness, C.
Values of fc are given in Table C9.T31.

C9.7.2.3.3. Airblast. (See paragraph C5.2.3. for special design considerations.)

C9.7.2.3.3.1. An explosion in an underground storage chamber may produce

external airblast from two sources; the exit of blast from existing openings (tunnel entrances,
ventilation shafts, etc.) and the rupture or breach of the chamber cover by the detonation.
Required IBD is independently determined for each of these airblast sources, with the maximum
IBD used for siting. If the chamber cover thickness is less than Cc given in subparagraph
C9.7.2.3.2., some external airblast will be produced depending on the cover thickness. Use the
following to determine IBD for airblast produced by breaching of the chamber cover:

[Metric EQN C9.T31-4]

C9.7.2.3.3.1.1. C < 0.25W1/3 ft [0.10Q1/3 m]: Use IBD for surface burst of
bare explosives charge (Table C9.T1., Note 4).

C9.7.2.3.3.1.2. 0.25W1/3 < C < 0.50W1/3 ft [0.10Q1/3 < C < 0.20Q1/3 m]: Use
1/2 of IBD for surface burst of bare explosives charge.

C9.7.2.3.3.1.3. 0.50W1/3 < C < 0.75W1/3 ft [0.20Q1/3 < C < 0.30Q1/3 m]: Use
1/4 of IBD for surface burst of bare explosives charge.

C9.7.2.3.3.1.4. 0.75W1/3 ft [0.30*Q1/3 m] < C: Airblast hazards from blast

through the earth cover are negligible relative to ground shock or debris hazards.

C9.7.2.3.3.2. Overpressure and debris hazards must be determined for each

facility opening whose cross-section area is five percent or more of that of the largest opening.

C9.7.2.3.3.2.1. Distance versus overpressure along the centerline axis of a

single opening is:
R = 149.3*DHYD*((W/VE)0.5/pSO)1/1.4 [English EQN C9.7-15]
R = 220.191*DHYD*((W/VE)0.5/pSO)1/1.4 [Metric EQN C9.7-16]
where:
R: Distance from opening (ft) [m],
DHYD: Effective hydraulic diameter that controls dynamic flow issuing from the
opening (feet) [m] (Compute D, using the minimum, cross-sectional area
of the tunnel that is located within five tunnel diameters of the opening, as
D = 4A/P, where A is the area and P is the perimeter.),
PSO: Overpressure at distance R (psi) [kPa],
W: MCE in lb [kg],
VE: Total volume engulfed by the blast wavefront within the tunnel system at
the time the wavefront arrives at the point of interest (ft3) [m3].

C9.7.2.3.3.2.2. Distance versus overpressure off the centerline axis of the

opening is:
R(T) = R(T=0)/(1 + (T/56)2)1/1.4 [English EQN C9.7-17]
where:
R(T =0) Distance along the centerline axis, and T is the horizontal angle from
the centerline (degrees).

C9.7.2.3.3.3. Equations [English EQN C9.7-15] [Metric EQN C9.7-16], and

[English EQN C9.7-17] show that the distance providing protection from an overpressure
exceeding PSO depends on the DHYD, and the angle from the centerline axis for the location of
interest. Table C9.T32. gives the ratio of off-axis to on-axis distances.

188 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.7.2.3.3.4. Find required IBD distances for airblast using the appropriate
equations discussed above, with the criteria that the total incident overpressure at IBD shall not
exceed:

PSO = 1.2 psi for W < 100,000 lbs,

PSO = 8.27 kPa for W < 45,359 kg,
PSO = 44.57*W-0.314 psi for 100,000 < W < 250,000 lbs [English EQN C9.7-18]
PSO = 239.753*W-0.314 kPa for 45,359 < W < 113,397.5 kg. [Metric EQN C9.7-19]
PSO = 0.9 psi for W > 250,000 lbs.
PSO = 6.21 kPa for W > 113,397.5 kg.

C9.7.2.3.3.5. For the overpressures of subparagraph C9.7.2.3.3.4, on-axis IBD

distances are:

R = 131.1*DHYD*(W/VE)1/2.8 for W < 100,000 lbs, [English EQN C9.7-20]

R = 48.683*DHYD*(W/VE)1/2.8 for W < 45,359 kg, [Metric EQN C9.7-21]
R = 9.91*DHYD*W0.581/VE0.357 for 100,000 <W < 250,000 lbs,
---- [English EQN C9.7-22]
R = 4.395*DHYD*W0.581/VE0.357 for 45,3599 < W < 113,397.5 kg,
---- [Metric EQN C9.7-23]
R = 161.0*DHYD*(W/VE)1/2.8 for W > 250,000 lbs [English EQN C9.7-24]
R = 59.787*DHYD*(W/VE)1/2.8 for W > 113,397.5 kg. [Metric EQN C9.7-25]

C9.7.2.3.3.6. QD distances for IBD for airblast may be determined from the
equations listed above or from entries in Tables C9.T33. and C9.T34.

C9.7.2.4. PTRD. PTRD for HD 1.1 is 60 percent of IBD for ground shock, debris, or
airblast, whichever is greater.

C9.7.2.5. ILD. ILD for HD 1.1 is the greater of the following:

C9.7.2.5.1. Ground Shock. Does not apply.

C9.7.2.5.2. Debris. For locations within 10 degrees of either side of the centerline of
a tunnel opening, site intraline facilities at IBD (see subparagraph C9.7.2.3.). QD criteria for
debris are not applicable to locations outside 10 degrees of either side of the centerline axis of an
opening.

C9.7.2.5.3. Airblast. Overpressure at barricaded and unbarricaded intraline distances

shall not exceed 12 psi [82.7 kPa] and 3.5 psi [24.1 kPa], respectively.

2. For IBD reductions with mitigating devices, see C5.2.3.3.

C9.8. FACILITIES SITING CRITERIA

This section establishes criteria for siting AE and non-AE facilities with respect to PES.

C9.8.1. Administration and Industrial Areas and Auxiliary Facilities

C9.8.1.1. Administration and industrial areas shall be separated from a PES by IBD.

C9.8.1.2. Auxiliary facilities (e.g., heating plants, line offices, break areas, briefing
rooms for daily work schedules or site safety matters, joiner shops, security posts, and similar
functions) located at or near AE operations and servicing only one building or operation may be
located at fire protection distance (50 ft [15.2 m] for non-combustible structures, 100 ft [30.5 m]
for combustible structures) from the building or operation they support.

C9.8.2. Classification Yard

C9.8.2.1. For protection of the classification yard from a PES, separation distances shall
be at least the applicable IMD.

C9.8.2.2. Specific QD separation is not required from the classification yard to ES when
the classification yard is used exclusively for:

C9.8.2.2.1. Receiving, dispatching, classifying, and switching of cars.

C9.8.2.2.2. Interchanging of trucks, trailers, or railcars between the common carrier

and the DoD activity.

C9.8.2.2.3. Conducting external inspection of motor vehicles or railcars, or opening

of free-rolling doors of railcars for the purpose of removing documents and making a visual
inspection of the cargo.

C9.8.2.3. Specific QD separation applies if the classification yard is used for any other
purpose.

194 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.3. Areas for Burning AE. Use the QD formula described in subparagraph C2.2.1.3.
and the requirements in subparagraphs C9.8.3.1. through C9.8.3.3. to determine safe locations
for burning AE.

C9.8.3.1. Use K24 [9.52] in the QD formula to determine the minimum safe distance for
either personnel burning AE or those conducting unrelated AE operations.

C9.8.3.2. Use K40 [15.87] in the QD formula to determine the safe distance for persons
not performing AE operations. However, if the NEWQD of burn material is more than 450 lbs
[204 kg], the minimum safe distance shall be at least 1,250 ft [381 m]. If the NEWQD of burn
material is < 450 lbs [204 kg], use the minimum HFD given in Table C9.T2.

C9.8.3.3. Locate burning grounds at ILD from other PES.

C9.8.4. Areas Used for Intentional Detonations

C9.8.4.1. General

C9.8.4.1.1. Protective structures for personnel or measures to suppress blast or

fragment effects may be used to reduce the required withdrawal distances.

C9.8.4.1.2. Control sites for intentional detonations for AE disposals, live-fire

demonstrations, and Explosive Ordnance Disposal (EOD) non-emergency operations must be at
ILD from other PES, based on the PES’s NEWQD.

C9.8.4.2. The minimum separation distances between areas used for intentional
detonation (excluding hands-on training) and nonessential personnel are determined by
application of the criteria given below. If the minimum separation distance requirements for
previously approved DDESB sitings or those prescribed in this section cannot be met, then
personnel shall be provided the protection specified in paragraph C4.3.2.

C9.8.4.2.1. For non-fragmenting AE, use d = 328W1/3 but not less than 1,250 ft [d =
1/3
130.1Q , but not less than 381 m]. If known, maximum debris throw distance, with a safety
factor determined by the DoD Component, may be used to replace the 1,250 ft [381 m] minimum
distance.

C9.8.4.2.2. For fragmenting AE use the larger of the two distances below:

C9.8.4.2.2.1. The distance determined from the equation d = 328W1/3 but not less
than 1,250 ft [d = 130.1Q1/3 but not less than 381 m].

C9.8.4.2.2.2. The distances given in Table C9.T35., based on the diameter of the
AE being destroyed. A calculated or measured maximum fragment throw distance (including the
interaction effects for stacks of items or single items, whichever applies), with a safety factor
determined by the DoD Component, may be used to replace these distances. Calculated case
fragment maximum throw distances for selected munitions are given in Table C9.T36. (The

195 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

calculated case fragment throw distances in Tables C9.T35. and C9.T36. are for individual items.
These throw distances do not consider “rogue” fragments that are produced by sections of nose
plugs, base plates, or lugs, and they do not directly apply to stacks of munitions. In addition,
shaped charge jets or slugs from directed energy munitions can travel significantly greater
distances than case fragments; therefore, these munitions require specific analysis.)

C9.8.4.2.2.2.1. “Rogue” fragments can travel significantly greater distances

(> 10,000 ft [3,048 m]) than those shown in Tables C9.T35. and C9.T36. Care must be taken
either to properly orient the munition (e.g., lugs or strongbacks and nose or tail plate sections
oriented away from personnel locations), or to minimize or eliminate the hazard of rogue
fragments (e.g., sandbagging the munition prior to detonation).

C9.8.4.2.2.2.2. For multiple munitions’ detonation, the preferred approach is:

C9.8.4.2.2.2.2.1. Place the munitions in a single layer with their sides

touching such that their axis is horizontal.

C9.8.4.2.2.2.2.2. Place the munitions so that the nose of each munition is

pointing in the same direction.

C9.8.4.2.2.2.2.3. Orient the munitions so that lugs or strongbacks and

nose or tail plate sections are facing away from areas to be protected.

C9.8.4.2.2.2.2.4. Initiate the stack detonation so that all munitions

detonate simultaneously.

C9.8.4.2.2.2.2.5. Use the following when the procedures outlined in

subparagraphs C9.8.4.2.2.2.2.1. through C9.8.4.2.2.2.2.4. cannot be met:

C9.8.4.2.2.2.2.5.1. If the orientation of the potential rogue fragments

can be controlled, then the ranges given in Tables C9.T35. and C9.T36. shall be increased by 20
percent to account for the interaction effects.

C9.8.4.2.2.2.2.5.2. If the orientation of potential rogue fragments

cannot be controlled, fragment ranges must be evaluated on a case-by-case basis.

C9.8.4.2.2.2.2.5.3. If detonations involve stacks of mixed munitions,

evaluate the distance for each munition separately using the procedures in subparagraph
C9.8.4.2.2.2. and select the largest distance.

Notes for Table C9.T35.:

1. These calculated fragment throw distances are for individual munitions and do not apply to stacks. They also
do not address “rogue” (non-case) fragments that can be produced from sections of nose plugs, base plates, or
lugs. Rogue fragments can travel to significantly greater distances (i.e., > 10,000 ft [3,048 m]) than those
shown. Care must be taken to properly orient the munition or take other measures to minimize rogue fragment
hazards.

Notes for Table C9.T36.:

1. These calculated case fragment throw distances are for individual items and do not apply to detonations
involving multiple munitions. See subparagraph C9.8.4.2.2.2. for application to detonation of multiple munitions.
In addition, shaped charge jets or slugs from directed energy munitions can travel significantly greater distances than
case fragments; therefore, these munitions require specific analysis.
2. These calculated fragment throw distances are for individual munitions and do not apply to stacks. They also
do not address “rogue” (non-case) fragments that can be produced from sections of nose plugs, base plates, or lugs.
Rogue fragments can travel to significantly greater distances (i.e., > 10,000 ft [3,048 m]) than those shown. Care
must be taken to properly orient the munition or take other measures to minimize rogue fragment hazards.

C9.8.4.3. EOD Operations

C9.8.4.3.1. EOD operational responses require the application of public withdrawal

distances to all nonessential personnel per Table C8.T4.

C9.8.4.3.2. EOD operations or demonstrations conducted on ranges require

minimum separation distances (see subparagraph C9.8.4.2.) for nonessential personnel.

C9.8.4.3.3. EOD training operations, or operations involving demolition of AE, do

not require minimum separation distances for essential personnel. The onsite DoD authority
shall determine adequate protection for essential personnel.

200 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.4.3.4. EOD Proficiency Training Ranges. EOD proficiency-training ranges are

limited to a maximum of 5 lbs [2.27 kg] of demolition explosives (e.g., bare charges or items
without a fragment hazard).

C9.8.4.3.4.1. Facilities that require IBD, PTRD, and ILD protection must be
located at the following minimum distances from the destruction point:

C9.8.4.3.4.1.1. If the destruction point is at least 500 ft [152.4 m] from these

facilities, a 5-lb [2.27 kg] NEWQD limit applies.

C9.8.4.3.4.1.2. If the destruction point is less than 500 ft [152.4 m], but 300 ft
[91.4 m] or more from these facilities, a 2.5-lb [1.13 kg] NEWQD limit applies.

C9.8.4.3.4.1.3. If the destruction point is less than 300 ft [91.4 m], but 200 ft
[61 m] or more from these facilities, a 1.25-lb [0.57 kg] NEWQD limit applies.

C9.8.4.3.4.2. Barricading of Destruction Point. If the EOD Proficiency Training

Range provides the 500-foot protection distance specified in subparagraph C9.8.4.3.4.1.1., then
no barricading of the destruction point is required. If the EOD Proficiency Training Range
provides less than 500 feet protection distance, then the range’s destruction point shall be
constructed to control ejection of debris by:

C9.8.4.3.4.2.1. Constructing a barricade with two entrances, which surrounds

the destruction point, that is the equivalent of at least two side-to-side sandbags, is at least 6 ft
[1.83 m] high, and is constructed within about 10 ft [3.05 m] of the destruction point.

C9.8.4.3.4.2.2. Locating the barricade entrances at 180 degrees separation.

These entrances shall be barricaded, as above, to effectively block all debris.

C9.8.4.3.4.3. EOD proficiency training ranges used with other than bare charges
or non-fragment producing items shall meet the requirements of subparagraph C9.8.4.1.

C9.8.4.3.4.4. EOD proficiency training ranges on which explosively operated

tool kits are used on inert AE only require 100 ft [30.5 m] separation distance between the
destruction point and facilities that require IBD, PTRD, and ILD protection. The site shall be
barricaded per subparagraph C9.8.4.3.4.2.

C9.8.4.4. Live-fire Demonstrations and Disposal Operations. The appropriate DoD

authority shall determine, on a case-by-case basis:

C9.8.4.4.1.1. Essential personnel required for the live-fire demonstrations or

disposal operations.

C9.8.4.4.1.2. Other range safety considerations (e.g., personnel withdrawal

distances and acceptable exposures).

201 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.5. Inert Storage. The DoD Components shall determine acceptable locations for inert
storage that is directly related to the explosives mission, and for inert storage that is not directly
related but where control of and access to such inert storage is restricted only to personnel
directly related to the explosives mission. The DoD Components shall determine what
constitutes “directly related.” The following apply to inert storage:

C9.8.5.1. Locations for inert storage shall be determined only after consideration of
personnel exposure, the importance of the materiel in relation to the explosives mission, the
operational conditions, and the availability of space.

C9.8.5.2. Site plans meeting the conditions above are not required to be submitted to the
DDESB for review and approval (see paragraph C5.5.9.).

C9.8.5.3. Inert storage that will be accessed by personnel not related to the explosives
mission shall be sited per subparagraphs C9.4.1.1.4.7. and C9.4.1.1.6.9. (based on blast only).
Minimum fragment distances do not apply (see subparagraph C9.4.1.2.1.3.4.).

C9.8.6. Interchange Yards

C9.8.6.1. Truck, trailer, or railcar interchange yards are not subject to QD requirements,
when used exclusively:

C9.8.6.1.1. For the interchange of vehicles or railcars containing AE between the

commercial carrier and DoD activities.

C9.8.6.1.2. To conduct external inspection of the trucks, trailers, or railcars

containing AE.

C9.8.6.1.3. To conduct visual inspection of the external condition of the cargo in

vehicles (e.g., trucks, trailers, and railcars) that passed the external inspection.

C9.8.6.2. Truck, trailer, or railcar interchange used, at any time, for any purpose other
than the above are subject to applicable Q-D tables. (See subparagraph C9.3.1.7.)

C9.8.7. Inter-DoD Component Support and Tactical Facilities

C9.8.7.1. General.

C9.8.7.1.1. The separation distances in subparagraph C9.8.7.2. shall apply between

facilities of one DoD Component to those of another DoD Component regardless of the location
of the boundaries.

C9.8.7.1.2. Other safety criteria (e.g., toxicity, noise, radiation, flight trajectory) may
require greater distances. In these situations, the predominant hazard criteria shall apply.

C9.8.7.2. The following minimum QD relationships apply:

202 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.7.2.1. AE storage facilities shall be separated by IMD.

C9.8.7.2.2. AE storage or operating locations of one DoD Component shall be

separated from AE operating locations of another DoD Component by IBD. (See subparagraph
C9.8.7.2.3. for an exception to this criterion.)

C9.8.7.2.3. Explosive operations that present a similar degree of hazard or involve

joint or support operations shall be separated by ILD.

C9.8.7.2.4. AE storage or operating locations of one DoD Component shall be

separated from AE tactical facilities of another DoD Component by IBD. For joint or support
operations, determine the separation distance as though both facilities belonged to a single DoD
Component.

C9.8.8. Detached Loading Docks. Detached loading docks that normally service multiple
facilities shall be sited on the basis of use.

C9.8.8.1. When servicing magazines, they must be separated from magazines by IMD.

C9.8.8.2. When servicing operating buildings, they must be separated from the operating
buildings by ILD.

C9.8.9. Holding Yards for Railcars and Trucks Containing AE

C9.8.9.1. Railcar groups containing AE shall be separated from each other by AGM
distance in a railcar holding yard. For example:

C9.8.9.1.1. If the railcar holding yard is formed by two parallel ladder tracks
connected by diagonal spurs, the parallel tracks and the diagonal spurs shall be separated by
AGM distance for the quantities of AE involved.

C9.8.9.1.2. If the railcar holding yard is a “Christmas tree” arrangement, consisting

of a ladder track with diagonal dead-end spurs projecting from each side at alternate intervals,
the spurs shall be separated by AGM distance for the quantities of AE involved.

C9.8.9.2. Truck groups containing AE in holding yards shall be separated from each
other by AGM distance.

C9.8.9.3. Both railcar and truck holding yards containing AE shall be separated from
other facilities by the applicable IBD, PTRD, ILD, or IMD.

C9.8.9.4. In addition to the temporary parking of railcars, trucks, or trailers containing

AE, holding yards may also be used to interchange truck, trailers, or railcars between the
commercial carrier and the DoD activity, and also to conduct visual inspections.

203 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.10. Inspection Stations for Railcars and Trucks Containing AE

C9.8.10.1. Inspection stations for railcars and trucks containing AE that are used
exclusively for the activities below are not subject to QD criteria. However, these stations
should be located as far as practical from other hazards or populated areas. Allowable activities
are:

C9.8.10.1.1. External visual inspection of the railcars or motor vehicles.

C9.8.10.1.2. Visual inspection of the external condition of the cargo packaging in

vehicles that have passed the external inspection indicated in subparagraph C9.8.10.1.1.

C9.8.10.1.3. Interchange of trucks, trailers, or railcars between the common carrier

and the DoD activity.

C9.8.10.2. Inspection stations used for any other purpose shall comply with applicable
QD criteria.

C9.8.11. Holding Areas for Suspect Railcars or Trucks Containing AE. Railcars or trucks
that are suspected of being in a hazardous condition shall be separated (isolated) from other PES
or ES by the applicable QD before any other action.

C9.8.12. AE Transportation Mode Change Locations. Movement and transfer of DoD-titled

AE must comply with national, international, and host country-specific transportation
regulations. QD criteria apply to all transfer operations involving DoD-titled AE.

C9.8.13. Secure Holding Area. An area designated for the temporary parking of commercial
carriers’ motor vehicles transporting DoD-owned Arms, Ammunition, and Explosives (AAE),
classified (SECRET or CONFIDENTIAL) materials, and Controlled Cryptographic Items (CCI).
There are two types of secure holding areas and the criteria for each are provided below.
(Although the intent of such areas is to provide a secure storage location for commercial carriers
while in transit, or during emergencies or other circumstances that are beyond a carrier’s control,
this Standard imposes no requirement for installations to have such areas. The term Secure
Holding Area is applicable to areas (CONUS, Hawaii, Alaska, and Puerto Rico) governed by
DoD 4500.9-R (Reference (aa)).)

C9.8.13.1. Secure Explosives Holding Area. Site as a holding yard per paragraph
C9.8.9.

C9.8.13.2. Secure Non-explosives Holding Area. No siting required if located outside

all QD arcs. If located within a QD arc, site as an administrative parking lot per subparagraph
C9.4.1.1.4.6. The holding of HD 1.4S materials, without regard to QD, is permitted at this
location.

C9.8.14. Storage Tanks for Hazardous Materials

204 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.14.1. Unprotected, aboveground bulk storage tanks shall be separated from PES by
IBD per Table C9.T1. A dike system satisfying Reference (s) is required. Aboveground storage
tanks that are provided protection against rupture or collapse from blast and fragment hazards
may be sited at distances less than Table C9.T1. when supported by testing or analysis.

C9.8.14.2. For installation of smaller bulk storage tanks, weigh the cost of distance or
protective construction against the strategic value of the stored material, the ease of replacement
in the event of an accident, and the potential environmental impact. Reduced distances may be
approved if:

C9.8.14.2.1. The losses are accepted by the DoD Component.

C9.8.14.2.2. The tanks are sited.

C9.8.14.2.3. Spill containment is provided so other exposures are not endangered.

C9.8.14.3. Unprotected service tanks solely supporting AE storage or operating

complexes that are supplied by a pipe system designed to resist blast and fragments may be sited
at IBD based on blast only with a minimum distance of 400 ft [121.9 m] if:

C9.8.14.3.1. A dike system meeting the requirements of Reference (s) is provided.

C9.8.14.3.2. The DoD Component accepts the possible loss of the tanks and any
collateral damage that a fire might cause as a result of the tanks being punctured by fragments.

C9.8.14.4. A service tank supporting a single PES shall be separated from that PES by
the applicable NFPA fire protection distance. The distance from this service tank to any other
PES shall be the larger of the required distance between the two PES or the applicable NFPA fire
protection distance.

C9.8.14.5. Buried tanks and buried pipelines should be separated from all PES
containing HD 1.2, HD 1.3, HD 1.4, or HD 1.6 AE by at least 80 ft [24.4 m]. The required
separation distance for HD 1.1 or HD 1.5 AE is K3 [1.19] with a minimum of 80 ft [24.4 m]. If
the PES is designed to contain the effects of an explosion, then no QD is required.

C9.8.14.6. Small quantities of POL or other hazardous materials used for operational
purposes require no specific separation distance for explosives safety; however, operating
procedures shall be implemented to limit adverse environmental impacts in the event of an
accidental explosion.

C9.8.14.7. For underground AE facilities, it is not practical to specify QD criteria that

cover all tank storage configurations. The DoD Component shall assess each configuration per
section C9.7 to ensure that equivalent protection of subparagraphs C9.8.14.1. through C9.8.14.6.
is provided.

C9.8.15. Storage Tanks for Water

205 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.15.1. Unprotected aboveground water storage tanks shall meet the siting
requirements of subparagraph C9.8.14.1. if loss of the tank is unacceptable to the DoD
Component. Buried tanks and associated components of like value shall meet the siting
requirements of subparagraph C9.8.14.5. Aboveground storage tanks that are provided
protection against rupture or collapse from blast and fragment hazards may be sited at distances
less than Table C9.T1. when supported by testing or analysis. No dike is required.

C9.8.15.2. QD criteria do not apply to water storage tanks and associated components if
loss is acceptable to the DoD Component.

C9.8.16. Underground Tanks or Pipelines for Non-Hazardous Materials. See subparagraph

C9.8.14.5.

C9.8.17. Temporary Construction or Maintenance Operations. Construction and

maintenance personnel who are temporarily near a PES to perform their job shall be provided the
maximum practicable protection from the effects of an explosion if one occurs at a PES. The
DoD Component shall determine the minimum practicable separation distance from PES for
such personnel and shall control operations at the PES to minimize personnel exposure to
hazards from an explosion. Documentation of the rationale for the control measures taken shall
be maintained until construction or maintenance operations are completed.

C9.8.18. Military Working Dog (MWD) Explosives Search Training. Training of MWD
involves searches to detect explosives that have been hidden in various public places. These
training operations typically include handling explosives, cutting or dividing explosive training
aids, removing explosives from shipping and storage containers, and repackaging explosives into
other containers. For these reasons, training operations shall:

C9.8.18.1. Be conducted by personnel meeting DoD Component qualifications.

C9.8.18.2. Be conducted in facilities that meet the requirements of this Standard.

C9.8.18.3. Store explosives in facilities that meet the requirements of this Standard.

C9.8.18.4. Provide non-essential personnel:

C9.8.18.4.1. 40W1/3 [15.87Q1/3] separation distance from the training site if more
than 15 lbs [6.8 kg] NEWQD are being used for the exercise.

C9.8.18.4.2. 100 ft [30.5 m] separation distance from the training site for NEWQD <
15 lbs [6.8 kg].

C9.8.18.5. Minimize the number of samples and the quantity of explosives for each
sample. The DoD Component shall determine the total quantity of explosives permitted during
an exercise considering:

206 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.18.5.1. The value and importance of the exposed facilities.

C9.8.18.5.2. The exercise operating conditions.

C9.8.18.5.3. The available separation distance for nonessential personnel.

C9.8.18.6. Separate samples a sufficient distance apart to prevent an explosion from

propagating from one sample to another.

C9.8.18.7. Not use any initiating devices or initiating explosives.

C9.8.18.8. Not place explosives near any heat or spark producing items (e.g., bare
electrical wiring, radiators, electric heaters, heating vents, etc.).

C9.8.18.9. Not place explosives in metal containers or other means of confinement that
could produce fragments in the event of an accidental explosion.

C9.8.19. Demilitarization Processing Equipment and Operations for Expended .50-Caliber

and Smaller Cartridge Casings

C9.8.19.1. A demilitarization operation for processing expended .50-caliber and smaller

cartridge cases can be treated as a non-explosive operation provided:

C9.8.19.1.1. Cartridge casings to be processed are screened prior to processing.

(Screening is intended to ensure that only .50-caliber and smaller are processed, and to remove
unused .50-caliber and smaller cartridges.)

C9.8.19.1.2. Demilitarization processing equipment is tested to be capable of

containing overpressure, fragment, and thermal hazards associated with a worst-case reaction
involving a single live round of the most energetic cartridge that could be processed in the
equipment.

C9.8.19.1.3. Demilitarization processing equipment is operated within the

manufacturer’s specifications and restricted only to the processing of expended .50-caliber and
smaller cartridge casings.

C9.8.19.1.4. Demilitarization processing equipment is inspected and maintained to

ensure safe operation.

C9.8.19.2. DoD Components shall:

C9.8.19.2.1. Approve the use of specific demilitarization processing equipment.

C9.8.19.2.2. Establish and implement procedures for:

C9.8.19.2.2.1. Screening and segregating the material to be processed.

207 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.19.2.2.2. Operating, inspecting, and maintaining the demilitarization

processing equipment to ensure safe operation.

C9.8.19.2.2.3. Dispositioning of processed material.

C9.8.19.3. Explosives Safety Siting

C9.8.19.3.1. Demilitarization processing operation locations meeting subparagraphs

C9.8.19.1. and C9.8.19.2., and located outside of IBD from all PES, do not require submission of
a site plan to the DDESB (see paragraph C5.5.10.).

C9.8.19.3.2. Locations used for demilitarization processing operations that are

located within IBD arcs:

C9.8.19.3.2.1. Require submission of a site plan to the DDESB.

C9.8.19.3.2.2. Shall be sited at ILD, except from the PES to which it is integral.

C9.8.20. Conveyance Loading and Unloading at a Magazine. A conveyance (e.g., truck,

trailer, railcar, ISO or Military Van (MILVAN) container) loading and unloading operation is
permitted at a magazine without regard to QD between the magazine and the operation. “At a
magazine” means loading and unloading operations at a loading dock attached to the magazine,
or on the pad/apron in front of the magazine, or within the established boundaries of an
aboveground magazine. Detached ramps or loading docks that normally service multiple
facilities will be sited in accordance with paragraph C9.8.8.

C9.8.21. Reduced QD Magazines. The below criteria address the use of DDESB-approved
reduced QD magazines (e.g., GOLAN 5, 10, and 15, NABCO SV-23 and SV-50, EOD
magazine, Advanced EOD Magazine, and other similar magazines listed in Table AP1-4. of
Reference (j)) for AE storage.

C9.8.21.1. Siting of Reduced QD Magazines

C9.8.21.1.1. Reduced QD magazines shall be sited as AGM, using the reduced QD

distances established as part of the DDESB approval package for each type of magazine.

C9.8.21.1.2. A DDESB-approved site plan is required prior to the use of a reduced

QD magazine for AE storage. However, when circumstances dictate, use of a magazine may
proceed before DDESB approval provided the Service-level explosives safety office (i.e.,
USATCES, NOSSA, MARCORSYSCOM PM AMMO, or AFSC) has reviewed and approved
the submission, the submission is at the DDESB for review and approval, and the DoD
Component accepts that the DDESB approval process may impose different or additional
requirements.

208 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.21.1.3. Siting of reduced QD magazines shall comply with specific provisions

for their use (e.g., venting, grounding) identified as part of the DDESB approval package for
each type of magazine.

C9.8.21.1.4. The QD distances approved by the DDESB for reduced QD magazines

do not account for the hazards presented to surrounding exposures when the magazine door is
open or when authorized AE operations are conducted at the magazine. The following criteria
are intended to minimize these hazards:

C9.8.21.1.4.1. The reduced QD magazine should be located and oriented to

maximize protection of surrounding exposures. The selection of a location for the reduced QD
magazine shall not be simply for convenience, but shall consider the direction of the door,
planned operations, and the need to minimize exposure of personnel and facilities.

C9.8.21.1.4.2. The reduced QD magazine door should be directed away from

occupied spaces and facilities, or at a minimum directed away from the highest exposures.

C9.8.21.1.4.3. For a reduced QD magazine authorized to contain up to 30 pounds

[13.60 kg] NEWQD of HD 1.1, a minimum 50-foot [15.24 m] separation distance should be
maintained from the door of the magazine, and from any authorized AE operation at the
magazine, to the nearest occupied space or facility. For a reduced QD magazine authorized to
contain 30 to 50 pounds [22.68 kg] NEWQD of HD 1.1, a minimum 100-foot [30.50 m]
separation distance should be maintained from the door of the magazine, and from any
authorized AE operation at the magazine, to the nearest occupied space or facility. At these
separation distances, only minor damage to exposed facilities is expected as a result of blast
overpressure; however, window breakage will likely occur and may present some risk to
personnel in exposed facilities. Fragmentation hazards are not addressed by these separation
distances. Barricades (see subparagraph C9.8.21.2.2.6.) may be used to stop low-angle, high-
velocity fragments, which present the greatest threat to surrounding exposures.

C9.8.21.2. Authorized Operations at Reduced QD Magazines. Significant personnel

exposure and risk reductions are obtained by the use of reduced QD magazines for AE storage,
even when short-duration explosives operations are conducted at such magazines. Therefore,
certain AE operations are authorized at a reduced QD magazine, without regard to QD. (NOTE:
AE operations not authorized below require siting as an operating location.)

C9.8.21.2.1. The following AE operations may be conducted at reduced QD

magazines without regard to QD, provided the requirements of subparagraph C9.8.21.2.2. are
met: (The below criteria and guidance modify the criteria and guidance for AE operations
identified as part of the DDESB approval package for each type of magazine.)

C9.8.21.2.1.1. The movement of packaged AE into and out of reduced QD

magazines.

209 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.21.2.1.2. The removal of internal packaged AE items from outer packaging

(e.g., removal of individually packaged dog scent kit samples from their larger shipping
container).

C9.8.21.2.1.3. The rotation and replacement of dynamite samples in dog scent

kits, as required to meet DoD criteria.

C9.8.21.2.1.4. The issuance of security or reaction force AE for installation force

protection, antiterrorism, or other similar mission.

C9.8.21.2.1.5. The removal and replacement of EOD materials contained in the

large pumice containers in the Advanced EOD Magazine. (This is because the pumice
containers are too large to transport in and out of the magazine.)

C9.8.21.2.1.6. The conduct of surveillance or inventory inspections that only

involve a visual serviceability inspection of AE.

C9.8.21.2.1.7. The placement of Munitions and Explosives of Concern (MEC)

that EOD personnel or Unexploded Ordnance (UXO)-qualified personnel have assessed and
determined acceptable for movement and storage in an appropriate reduced QD magazine
located at a Munitions Response Site (MRS).

C9.8.21.2.1.8. The conduct of other similar AE operations, provided:

C9.8.21.2.1.8.1. No direct energy is applied to the AE being handled (e.g.,

cutting, dividing, or crushing), except as allowed in subparagraph C9.8.21.2.1.9.

C9.8.21.2.1.8.2. The AE being handled have not been sensitized or made

more sensitive to initiation (e.g., primed).

C9.8.21.2.1.8.3. The AE being handled are not in a configuration that makes

them more susceptible to an unintentional detonation.

C9.8.21.2.1.9. The cutting of non-fragmenting AE (e.g., detonation cord, C4)

designed to be cut using authorized cutting tools, provided all nonessential personnel are
removed to a 40W1/3 [15.87Q1/3] separation distance with a 100 ft [30.5 m] minimum.

C9.8.21.2.2. The following requirements apply to authorized AE operations at

reduced QD magazines:

C9.8.21.2.2.1. The total NEWQD present (i.e., within the magazine and involved
in the operation) shall not exceed the rated NEWQD of the reduced QD magazine.

C9.8.21.2.2.2. To minimize the size and effects of an unintentional detonation,

operations conducted at reduced QD magazines shall be limited to the smallest MCE possible.

210 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.21.2.2.3. AE operations should not be conducted inside reduced QD

magazines unless absolutely necessary (as in the case of the Advanced EOD Magazine).
Conducting AE operations inside a magazine increases the MCE and the directional effects of an
internal explosion out the door.

C9.8.21.2.2.4. AE operations at reduced QD magazines should be conducted at

times when the exposure of unrelated personnel is at a minimum (i.e., at night; before or after
work shifts; on weekends).

C9.8.21.2.2.5. To take advantage of the barricade-type protection offered by the

reduced QD magazine structure, AE operations outside of reduced QD magazines shall be
conducted:

C9.8.21.2.2.5.1. As close to the base of the magazine as possible, with the

magazine door closed and secured (not required if the magazine does not contain AE).

C9.8.21.2.2.5.2. On the side of the magazine that is oriented away from the
surrounding area having the greatest exposure to be protected.

C9.8.21.2.2.6. Consideration should be given to constructing a barricade (to

defeat high-velocity, low-angle fragments) for AE operations at reduced QD magazines.
Acceptable barricading materials include sandbags and timber sand-filled walls; the barricade
shall not generate additional debris hazards. The barricade must be at least 6 feet [1.83 m] high,
provide line-of-sight protection between AE operations and exposures to be protected, and be the
equivalent of two side-by-side sandbags.

C9.8.22. Criteria for Non-DoD Explosives Activities (AE Operations and Storage) on DoD
Installations

C9.8.22.1. Non-DoD explosives activities shall only be conducted on DoD property per
Table C9.T37. These non-DoD explosives activities must also comply with Bureau of Alcohol,
Tobacco, and Firearms (BATF), Federal Aviation Administration (FAA), and other Federal,
State, and local regulations. Definitions for the terminology used in Table C9.T37. can be found
in the Glossary.

C9.8.22.2. For these types of non-DoD explosives activities, the Department of Defense
shall be responsible for ensuring that IMD requirements only, as outlined in explosives site plan
submissions, are met. DoD oversight of these non-DoD explosives activities is not intended.

C9.8.22.3. Non-DoD, explosives activities shall be evaluated based on IMD between

multiple PES to ensure non-propagation. Where IMD is not met, then the NEW at each site not
meeting IMD separation requirements shall be added together to determine the basis for the
applicable IMD or IBD to use for separation of DoD sites.

C9.8.22.4. In Table C9.T37., “Check for IMD” means if IMD is not maintained between
each PES, explosives quantities shall be totaled.

211 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.22.5. IBD shall be determined based on this Standard.

C9.8.22.6. The DoD site approval for non-DoD, explosives activities is limited to the
area encumbered by the IBD arcs.

C9.8.22.7. Review of building design, lightning protection, etc., is not necessary unless
design features are used as justification to reduce the IBD arc.

C1. CHAPTER 1
INTRODUCTION

C1.1. GENERAL

C1.1.1. These explosive safety standards (hereafter referred to as “Standards”) are issued
under the authority of DoD Directive 6055.9E (Reference (a)). These Standards are designed to
manage risks associated with DoD-titled ammunition and explosives (AE) by providing
protection criteria to minimize serious injury, loss of life, and damage to property. It is DoD
policy to comply with the applicable Federal and State laws and regulations. Where the Standard
conflicts with such laws and regulations, DoD components shall ensure the safety of DoD
personnel and the public while complying and notify the Chairman, DDESB, through its Board
Member, of the conflict. These Standards are not intended to be so rigid as to prevent the DoD
Components from accomplishing their assigned missions.

C1.1.2. Criteria provided by these Standards are given in English units (e.g., ft, lb, psi.) with
metric equivalents shown in brackets (e.g., [m, kg, kilopascal (kPa)]).

C1.2. EXPLOSIVES SAFETY MANAGEMENT (ESM) POLICY

As established in DoD Directive 6055.9E (Reference (a)) and consistent with peacetime,
contingency, or wartime operational requirements and corresponding DoD military munitions
requirements from the broadest and most fundamental Explosives Safety Management (ESM)
perspective, it is DoD policy to:

C1.2.1. Provide the maximum possible protection to people and property from the potential
damaging effects of DoD military munitions (explosive and chemical). Applying the Standards
herein provides only the minimum protection criteria for personnel and property, and greater
protection should always be provided when practicable.

C1.2.2. Minimize exposures consistent with safe and efficient operations (i.e., expose the
minimum number of people for the minimum time to the minimum amount of explosives or
chemical agents).

C1.3. APPLICABILITY

These Standards:

C1.3.1. Apply to DoD-titled AE wherever it is located.

C1.3.2. Apply to DoD personnel and property when potentially endangered by known
host-nation or off-installation AE hazards.

19 CHAPTER 1
DoD 6055.09-STD, February 29, 2008

C1.3.3. Govern DoD facilities siting and construction, except as indicated in paragraph
C1.3.5.

C1.3.4. Apply to the evaluation of non-DoD explosives siting submissions on DoD installations
(see paragraph C9.8.22.).

C1.3.5. Do not apply for the exceptions described in subparagraphs C1.3.5.1. through
C1.3.5.3. These exceptions must be documented per subparagraph C1.3.5.4.

C1.3.5.1. Existing facilities, or those approved for construction under then-current

editions of these Standards. This exception applies for the balance of the useful lives of such
facilities provided:

C1.3.5.1.1. The facility continues to be used for its intended purpose.

C1.3.5.1.2. The explosives safety hazards are not increased.

C1.3.5.1.3. Redesign or modification is not practicable.

C1.3.5.1.4. The quantity of AE cannot be reduced for reasons of operational

necessity.

C1.3.5.2. Those planned facilities that do not meet these Standards, but have been
certified by the Head of the DoD Component (see paragraph C1.5.4.) as essential for operational
or other compelling reasons.

C1.3.5.3. To other situations that, upon analysis by both the DoD Component and the
Department of Defense Explosives Safety Board (DDESB), are determined to provide the
required degree of safety through use of protective construction or other specialized safety
features.

C1.3.5.4. The DoD Components must document the above exceptions in permanent
records. These records must include:

C1.3.5.4.1. The effective date the applicable Standards were first published.

C1.3.5.4.2. The date the deviant facility was either approved, from an explosives
safety viewpoint, for use or was first used in the deviating manner.

C1.4. TERMINATION OF USE OF FACILITIES STORING AE

Each storage facility no longer used to store ammunition and explosives must undergo a process
to ensure that AE and any visible explosives residues are removed within 180 days from the last
use of the storage facility. Those procedures help ensure that no threats to human health or the
environment remain when the unit is no longer to be used to store AE. (Ammunition storage

20 CHAPTER 1
DoD 6055.09-STD, February 29, 2008

units (ASU) that have been used to store waste military munitions must also comply with the
closure procedures in Chapter 14, section C14.6.) Those procedures shall include the following:
C1.4.1. Emptying the storage facility of all AE and related materials.

C1.4.2. Cleaning the storage facility, as required, to remove any visible explosives residue.

C1.4.3. Visually inspecting the storage facility for the presence of remaining ammunition or
explosives or visible explosives residue by a knowledgeable individual appointed by the
installation or responsible activity commander.

C1.4.4. Removing from the storage facility all fire and chemical hazard symbols and
marking the storage facility as empty.

C1.4.5. Securing the storage facility to prevent inadvertent use or access.

C1.4.6. Notifying the applicable emergency response and regulatory authorities of the
change in the storage facility’s use.

C1.4.7. Recording the date the storage facility was inspected, the name and position of the
inspector, and the results in permanent real estate records.

C1.5. WAIVERS, EXEMPTIONS, AND SECRETARIAL EXEMPTIONS OR

CERTIFICATIONS

C1.5.1. General. When strategic or compelling operational requirements necessitate

deviation from these Standards, the DoD Component shall:

C1.5.1.1. Acknowledge and accept the added risk to personnel or property.

C1.5.1.2. Document both the risk and methods used to reduce it to an acceptable level in
relation to the operational requirements.

C1.5.2. Waivers. A waiver is a written authority that permits temporary deviation from
these Standards for strategic or compelling operational requirements. Generally, it is granted for
a period not to exceed 5 years pending termination of the waiver or correction of the waived
conditions. Exceptional situations may require a waiver to be reissued to allow either
completion of the operation requiring the waiver or time for completion of the corrective action.
In such cases, the next higher approval authority shall reissue the waiver; the exception is when
the head of the DoD Component or the responsible Combatant Commander has issued the
waiver. Waivers shall be reviewed for applicability and currency at intervals not to exceed 2
years. Waivers may be granted by the official with both:

C1.5.2.1. The assigned responsibilities consistent with the level of risk.

21 CHAPTER 1
DoD 6055.09-STD, February 29, 2008

C1.5.2.2. The authority to control the resources required to accomplish the corrective
action.

C1.5.3. Exemptions. An exemption is a written authority that permits long-term

noncompliance with these Standards for strategic or compelling operational requirements.
Exemptions shall be reviewed for applicability and currency at intervals not to exceed 5 years.
Exemptions may be granted by law, Congressional action, and the official assigned
responsibilities consistent with the level of risk.

C1.5.4. Secretarial Exemptions or Certifications. A Secretarial Exemption or Certification is

a written authority granted by a Secretary of a Military Department to deviate from the
requirements of these Standards to allow the construction of new potential explosion sites (PES)
or exposed sites (ES). To validate the strategic or compelling operational requirements and
ensure the identification of risks and exposures, these exemptions or certifications shall be
reviewed at intervals not to exceed 5 years.

C1.5.5. Report Control Symbol (RCS) DD-AT&L(AR)1643. (See DoD 8910.1-M

(Reference (b)).) When the DDESB requests information on exemptions and waivers, the DoD
Components shall provide the following, as applicable:

C1.5.5.1. Identification number (DoD Component-derived).

C1.5.5.2. Classification (waiver or exemption); approval authority’s title; and date of

approval, expiration, or cancellation, as applicable.

C1.5.5.3. Location.

C1.5.5.4. Condition waived or exempted.

C1.5.5.5. Net Explosive Weight (NEW) or Net Explosive Weight for Quantity-Distance
(NEWQD) by Hazard Division (HD) at a PES.

C1.5.5.6. Distance from the PES to any ES and a brief description of the ES to include:
type, estimated value of any property involved, and location of the property (e.g., on or off
installation).

C1.5 5.7. Estimated number of DoD and non-DoD personnel located at the ES.

C1.5.5.8. Calculated hazard distances (see public exclusion distance), as applicable.

C2. CHAPTER 2
REACTION EFFECTS

C2.1. INTRODUCTION

This chapter describes the expected effects of AE reactions.

C2.2. HD 1.1 EFFECTS

C2.2.1. Blast

C2.2.1.1. Blast Wave Phenomena. In an incident involving HD 1.1 or HD 1.1 with any
other HD (a HD 1.1 event), the violent release of energy creates a sudden and intense pressure
disturbance termed the “blast wave.” The blast wave is characterized by an almost instantaneous
rise from ambient pressure to a peak incident pressure (Pi). This pressure increase, or “shock
front,” travels radially outward from the detonation point, with a diminishing velocity that is
always in excess of the speed of sound in that medium. Gas molecules making up the front
move at lower velocities. This velocity, which is called the “particle velocity,” is associated with
the “dynamic pressure,” or the pressure formed by the winds produced by the shock front.

C2.2.1.1.1. As the shock front expands into increasingly larger volumes of the
medium, the incident pressure decreases and, generally, the duration of the pressure-pulse
increases.

C2.2.1.1.2. If the shock wave impinges a rigid surface (e.g., a building) at an angle to
the direction of the wave’s propagation, a reflected pressure is instantly developed on the surface
and this pressure rises to a value that exceeds the incident pressure. This reflected pressure is a
function of the incident wave’s pressure and the angle formed between the rigid surface and the
plane of the shock front.

C2.2.1.2. Partially Confined Explosions. When an explosion occurs within a structure,

the peak pressure associated with the initial shock front will be both high and amplified by
reflections within the structure. In addition, the accumulation of gases from the explosion will
exert additional pressure and increase the load duration within the structure. This effect may
damage or destroy the structure unless the structure is designed to either withstand or vent the
gas and shock pressures. Structures that have one or more strengthened walls may be vented for
relief of excessive gas by either using frangible construction for the remaining walls or roof or
through the use of openings. This type of construction will allow the gas from an internal
explosion to spill out of the structure. Once released from confinement, these pressures, referred
to as “exterior” or “leakage” pressures, expand radially and may affect external structures or
personnel.

C2.2.1.3. Quantity-Distance (QD) – K-factors. Throughout this Standard, NEW is used

to calculate Quantity-Distance (QD) by means of a formula of the type D (ft) = K•W1/3, where

23 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

“D” is the distance in feet, “K” is a factor (also called K-factor) that is dependent upon the risk
assumed or permitted, and “W” is the NEW in pounds. When metric units are used, the symbol
“Q” denotes Net Explosive Quantity (NEQ) in kilograms. In the formula D (m) = Km•Q1/3, the
distance “D” is expressed in meters. Thus, the units of the K-factor ("K" in the English system)
are ft/lb1/3 and ("Km" in the metric system) m/kg1/3. The value of “K” in English units is
approximately 2.52 times “Km.” For example, if D (m) = 6•Q1/3, then D (ft) = 15.12•W1/3.
Distance requirements determined by the formula with English units are sometimes expressed by
the value of “K,” using the terminology K9, K11, K18, to mean K = 9, K = 11, and K = 18.

C2.2.1.4. Expected Blast Pressures at QD. Table C2.T1. presents the incident pressures
that would be expected at various K-factors from HD 1.1 events.

C2.2.1.5. General Blast Effects On Structures

C2.2.1.5.1. Conventional Structures. Conventional structures are generally designed

to withstand roof-snow loads of 0-50 pounds per square foot [0-2.4 kPa] or wind loads up to 90
miles per hour [145 kilometers per hour] or both. At 90 mph [145 kph], the wind load equates to

24 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

0.14 psi [1.0 kPa]. Given the pressures shown in Table C2.T1. for the selected K-factors, it is
evident that, even at IBD, conventional structures may not provide complete protection from the
blast. Generally, the weakest portions of any conventional structure are the windows. Table
C2.T2. provides the probability of breaking typical windows at various K-factors and associated
incident pressures from HD 1.1 events.

25 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.1.5.2. Above Ground Structures (AGS). These are generally considered

conventional structures and provide little protection from blast or fragmentation. (See paragraph
C2.2.5.).

C2.2.1.5.3. Earth-Covered Magazines (ECM). High reflected pressure and impulse

produced by an explosion at an adjacent ECM can damage doors and headwalls and propel
debris into an ECM so that explosion is communicated by impact of such debris upon the
contents. When separated from each other by the minimum distances required by Table C9.T6.,
ECM (see paragraph C5.2.1.) provide virtually complete protection of AE against the
propagation effects of an explosion. However, AE in adjacent ECM may be damaged and
structural damage ranging from cracks in concrete, damage to ventilators and doors, to complete
structural failure, may occur. (When ECM containing HD 1.1 AE are sited so that any one is in
the forward sector of another, the two must be separated by distances greater than the minimum
permitted for side-to-side orientations. The greater distances are required primarily for the
protection of door and headwall structures against blast from a PES forward of the exposed
magazine, and to a lesser extent due to the directionality of effects from the source.)

C2.2.1.5.4. Underground Storage Facilities. Underground facilities sited per section

C9.7. provide a high degree of protection against propagation of an explosion between chambers,
and between underground and aboveground structures. An HD 1.1 explosion in an underground
storage facility causes very high pressures of prolonged duration. Blast waves and the
accompanying gas flows will travel throughout the underground facility at high velocity.

C2.2.1.5.5. Barricaded Open-Storage Modules. Barricaded open-storage modules

(see paragraph C5.2.2.) provide a high degree of protection against propagation of explosion.
However, if flammable materials are present in nearby cells, subsequent propagation of
explosion by fire is possible. When an explosion occurs, AE in adjacent modules separated by
K1.1 [Km 0.44] will be thrown tens of meters, covered with earth, and unavailable for use until
extensive uncovering operations, and possibly maintenance, are completed. Items at K2.52
[Km 1.0] separation distance from a donor explosion are expected to be readily accessible.

C2.2.1.5.6. High Performance Magazine (HPM). When separated from other AE

storage magazines by the minimum distances required by Table C9.T6., the HPM provides
virtually complete protection of AE against the propagation effects of an explosion. The HPM’s
2-story transfer and storage areas are enclosed by a pre-engineered metal building, which may be
severely damaged as a result of an explosion at a nearby PES. The amount of damage to be
expected at various pressure levels is described in paragraph C2.2.5. Access to the AE in a HPM
may require extensive cleanup and the use of a mobile crane, unless special design
considerations are incorporated into the metal building design. The HPM contains multiple
storage cells, which are designed to limit the maximum credible event, as discussed in
subparagraph C9.3.1.1.3. In the event of an internal explosion involving the maximum credible
event (MCE), the pre-engineered metal building can be expected to be completely destroyed, and
AE not involved in the explosion can be expected to be significantly damaged and no longer
usable.

26 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.1.6. General Blast Effects on Personnel. Tables C2.T3. through C2.T5. describe
the expected effects of blasts on personnel.

C2.2.1.7. Computation of Blast Effects. Many of the blast effects described in this
section were computed with the DDESB Blast Effects Computer (Reference (c)), which can be
used to estimate similar effects associated with various NEW, facilities, and distances.

C2.2.2. Fragments

C2.2.2.1. General. An important consideration in the analysis of the hazards associated

with an explosion is the effect of any fragments produced. Although most common in HD 1.1 or
HD 1.2 events, fragmentation may occur in any incident involving AE. Depending on their
origin, fragments are referred to as “primary” or “secondary” fragments.

C2.2.2.1.1. Primary fragments result from the shattering of a container (e.g., shell
casings, kettles, hoppers, and other containers used in the manufacture of explosives and rocket
engine housings) in direct contact with the explosive. These fragments usually are small,
initially travel at thousands of feet per second, and may be lethal at long distances from an
explosion.

C2.2.2.1.2. Secondary fragments are debris from structures and other items in close
proximity to the explosion. These fragments, which are somewhat larger in size than primary
fragments and initially travel at hundreds of feet per second, do not normally travel as far as
primary fragments.

C2.2.2.1.3. The earth cover of an underground facility may rupture and create a
significant debris hazard.

C2.2.2.1.4. A hazardous fragment is one having an impact energy of 58 ft-lb

[79 joules] or greater.

C2.2.2.1.5. The Hazardous Fragment Distance is the distance at which the areal
density of hazardous fragments or debris becomes one per 600 ft2 [55.7 m2].

C2.2.3. Thermal Hazards

C2.2.3.1. General. Generally, thermal hazards from a HD 1.1 event are of less concern
than blast and fragment hazards.

28 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.3.2. Personnel. It normally takes longer to incur injury from thermal effects than
from either blast or fragmentation effects because both blast and fragmentation occur almost
instantaneously. The time available to react to a thermal event increases survivability.

C2.2.3.3. Structures, Material, and AE. The primary thermal effect on structures,
material, and AE is their partial or total destruction by fire. The primary concern with a fire
involving AE is that it may transition to a more severe reaction, such as a detonation.

C2.2.4. Groundshock and Cratering

C2.2.4.1. General

C2.2.4.1.1. In an airburst, there may be a downward propagation of groundshock and

cratering may be reduced or eliminated.

C2.2.4.1.2. In a surface burst, groundshock is generated and cratering can be

significant.

C2.2.4.1.3. A buried or partially buried detonation produces the strongest

groundshock; however, if the explosion is deep enough, no crater will be formed.

C2.2.4.2. Underground Facilities. AE protection can be achieved by proper chamber

spacing. An HD 1.1 explosion will produce ground shocks that may rupture the earth cover and
eject debris. (See section C9.7.)

C2.2.5. Expected Consequences

C2.2.5.1. Barricaded Aboveground Magazine (AGM) Distance - 6W1/3 ft [2.38Q1/3 m] -

27 psi [186.1 kPa]. At this distance:

C2.2.5.1.1. Unstrengthened buildings will be destroyed.

C2.2.5.1.2. Personnel will be killed by blast, by being struck by debris, or by impact

against hard surfaces.

C2.2.5.1.3. Transport vehicles will be overturned and crushed by the blast.

C2.2.5.1.4. Explosives-loaded vessels will be damaged severely, with propagation of

explosion likely.

C2.2.5.1.5. Aircraft will be destroyed by blast, thermal, and debris effects.

C2.2.5.1.6. Control. Barricades are effective in preventing immediate propagation of

explosion by high-velocity, low-angle fragments. However, they provide only limited protection

29 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

against any delayed propagation of explosives caused by a fire resulting from high-angle
firebrands.

C2.2.5.2. Barricaded Intraline Distance (ILD) - 9W1/3 ft [3.57Q1/3 m] - 12 psi [82.7 kPa].
At this distance:

C2.2.5.2.1. Unstrengthened buildings will suffer severe structural damage

approaching total destruction.

C2.2.5.2.2. Personnel will be subject to severe injuries or death from direct blast,
building collapse, or translation.

C2.2.5.2.3. Aircraft will be damaged beyond economical repair both by blast and
fragments. If the aircraft are loaded with explosives, delayed explosions are likely to result from
subsequent fires.

C2.2.5.2.4. Transport vehicles will be damaged heavily, probably to the extent of

total loss.

C2.2.5.2.5. Improperly designed barricades or structures may increase the hazard

from flying debris, or may collapse in such a manner as to increase the risk to personnel and
equipment.

C2.2.5.2.6. Control. Barricading is required. Direct propagation of explosion

between two explosive locations is unlikely when barricades are placed between them to
intercept high-velocity, low-angle fragments. Exposed structures containing high-value,
mission-critical equipment or personnel may require hardening.

C2.2.5.3. Unbarricaded AGM Distance - 11W1/3 ft [4.36Q1/3 m] - 8 psi [55.3 kPa]. At

this distance:

C2.2.5.3.1. Unstrengthened buildings will suffer damage approaching total

destruction.

C2.2.5.3.2. Personnel are likely to be injured seriously due to blast, fragments,

debris, and translation.

C2.2.5.3.3. There is a 15 percent risk of eardrum rupture.

C2.2.5.3.4. Explosives-loaded vessels are likely to be damaged extensively and

delayed propagation of explosion may occur.

C2.2.5.3.5. Aircraft will be damaged heavily by blast and fragments; destruction by

resulting fire is likely.

30 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.5.3.6. Transport vehicles will sustain severe body damage, minor engine
damage, and total glass breakage.

C2.2.5.3.7. Control. Barricading will significantly reduce the risk of propagation of

explosion and injury of personnel by high-velocity, low-angle fragments.

C2.2.5.4. Unbarricaded ILD - 18W1/3 ft [7.14Q1/3 m] - 3.5 psi [24 kPa]. At this distance:

C2.2.5.4.1. Direct propagation of explosion is not expected.

C2.2.5.4.2. Delayed propagation of an explosion may occur at the ES, as either a

direct result of a fire or as a result of equipment failure.

C2.2.5.4.3. Damage to unstrengthened buildings may approximate 50 percent, or

more, of the total replacement cost.

C2.2.5.4.4. There is a two percent chance of eardrum damage to personnel.

C2.2.5.4.5. Personnel may suffer serious injuries from fragments, debris, firebrands,
or other objects.

C2.2.5.4.6. Fragments could damage the decks and superstructure of cargo ships and
overpressure could buckle their doors and bulkheads on weather decks.

C2.2.5.4.7. Aircraft can be expected to suffer considerable structural damage from

blast. Fragments and debris are likely to cause severe damage to aircraft at distances calculated
from the formula 18W1/3 [7.2Q1/3] when small quantities of explosives are involved.

C2.2.5.4.8. Transport vehicles will incur extensive, but not severe, body and glass
damage consisting mainly of dishing of body panels and cracks in shatter-resistant window glass.

C2.2.5.4.9. Control. Suitably designed suppressive construction at PES or protective

construction at ES may be practical for some situations. Such construction is encouraged when
there is insufficient distance to provide the required protection.

C2.2.5.5. Public Traffic Route Distance (PTRD) (under 100,000 lbs of High Explosives
(HE)) 24W1/3 ft [9.52Q1/3 m] - 2.3 psi [15.8 kPa]. At this distance:

C2.2.5.5.1. Unstrengthened buildings can be expected to sustain damage

approximately 20 percent of the replacement cost.

C2.2.5.5.2. Occupants of exposed structures may suffer temporary hearing loss or

injury from blast effects, building debris and displacement.

C2.2.5.5.3. Although personnel in the open are not expected to be killed or seriously
injured by blast effects, fragments and debris may cause some injuries. The extent of these

31 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

injuries depends largely upon the PES structure and the amount and fragmentation characteristics
of the AE involved.

C2.2.5.5.4. Vehicles on the road should suffer little damage, unless they are hit by a
fragment or the blast causes a momentary loss of control.

C2.2.5.5.5. Aircraft may suffer some damage to the fuselage from blast and possible
fragment penetration, but should be operational with minor repair.

C2.2.5.5.6. Cargo-type ships should suffer minor damage to deck structure and
exposed electronics from blast and possible fragment penetration, but such damage should be
readily repairable.

C2.2.5.5.7. Control. Barricading can reduce the risk of injury or damage due to
fragments for limited quantities of AE at a PES. When practical, suitably designed suppressive
construction at the PES or protective construction at the ES may also provide some protection.

C2.2.5.6. PTRD (over 250,000 lbs HE) 30W1/3 ft [11.9Q1/3 m] - 1.7 psi [11.7 kPa]. At
this distance:

C2.2.5.6.1. Unstrengthened buildings can be expected to sustain damage that may

approximate 10 percent of their replacement cost.

C2.2.5.6.2. Occupants of exposed, unstrengthened structures may be injured by

secondary blast effects, such as falling building debris.

C2.2.5.6.3. Pilots of aircraft that are landing or taking off may lose control and crash.

C2.2.5.6.4. Parked military and commercial aircraft will likely sustain minor damage
due to blast, but should remain airworthy.

C2.2.5.6.5. Although personnel in the open are not expected to be killed or seriously
injured by blast effects, fragments and debris may cause some injuries. The extent of these
injuries will largely depend upon the PES structure, the NEW, and the fragmentation
characteristics of the AE involved.

C2.2.5.6.6. Control. Barricading or the application of minimum fragmentation

distance requirements may reduce the risk of injury or damage due to fragments for limited
quantities of AE at a PES.

C2.2.5.7. Inhabited Building Distance (IBD) 40W1/3 ft - 50W1/3 ft [15.87Q1/3 - 19.8Q1/3

m] - 1.2 psi - 0.90 psi [8.3 kPa - 6.2 kPa]. At this distance:

C2.2.5.7.1. Unstrengthened buildings can be expected to sustain damage that

approximates five percent of their replacement cost.

32 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.2.5.7.2. Personnel in buildings are provided a high degree of protection from

death or serious injury; however, glass breakage and building debris may still cause some
injuries.

C2.2.5.7.3. Personnel in the open are not expected to be injured seriously by blast
effects. Fragments and debris may cause some injuries. The extent of injuries will depend upon
the PES structure and the NEW and fragmentation characteristics of the AE involved.

C2.2.5.7.4. Control. Elimination of glass surfaces is the best control. If determined

to be necessary, reducing the use of glass or the size of any glass surfaces and the use of blast-
resistant glass will provide some relief. For new construction, building design characteristics
should include consideration of how any required glass surfaces are oriented and use of blast-
resistant glass to reduce glass breakage and structural damage.

C2.3. HD 1.2 EFFECTS

C2.3.1. Blast

C2.3.1.1. HD 1.2, when not stored with HD 1.1 or HD 1.5, is not expected to mass
detonate. In an incident involving HD 1.2, when stored by itself or with HD 1.3, HD 1.4, or HD
1.6 (a HD 1.2 event), AE can be expected to both explode sporadically and burn. Fire will
propagate through the mass of the AE over time. Some AE may neither explode nor burn. Blast
effects from the incident are limited to the immediate vicinity and are not considered to be a
significant hazard.

C2.3.1.2. An HD 1.2 event may occur over a prolonged period of time. Generally, the
first reactions are relatively nonviolent and, typically, begin a few minutes after flames engulf
the AE. Later reactions tend to be more violent. Reactions can continue for some time (hours),
even after a fire is effectively out. Generally, smaller AE tends to react earlier in an incident
than larger AE.

C2.3.1.3. The results of an accidental explosion in an underground facility will depend

on the type and quantity of munitions, the type of explosion produced, and the layout of the
facility. Hazards created outside the underground facility will likely not be as severe as those
produced by HD 1.1 or 1.3 material.

C2.3.2. Fragments

C2.3.2.1. The primary hazard from a HD 1.2 event is fragmentation. Fragmentation may
include primary fragments from AE casings or secondary fragments from containers and
structures. At longer ranges, primary fragments are the major contributors to fragment hazards.

C2.3.2.2. During a HD 1.2 event, fragmentation may extensively damage exposed

facilities. However, less fragmentation damage can be expected from a given quantity of HD 1.2

33 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

than would be expected from the corresponding quantity of HD 1.1 because not all the HD 1.2
will react.

C2.3.3. Thermal Hazards

C2.3.3.1. An incident involving a quantity of HD 1.2 poses considerably less thermal

risk to personnel than an incident involving corresponding quantities of either HD 1.1 or HD 1.3
because a HD 1.2 event’s progressive nature allows personnel to immediately evacuate the area.

C2.3.3.2. A HD 1.2 event’s progressive nature provides an opportunity for a fire

suppression system, if installed, to put out a fire in its early stages.

C2.3.4. Ejected Items. In HD 1.2 events, a reaction may eject (lob) unreacted-AE or AE
components from the event site. These ejected items may subsequently react.

C2.3.5. Propelled Items. In HD 1.2 events, some AE or AE components may become

propulsive and travel well beyond IBD.

C2.3.6. Firebrands. In an incident involving only HD 1.2 or HD 1.2 with HD 1.4,

firebrands are considered to be a hazard only in the immediate vicinity of the incident site.

C2.3.7. Expected Consequences

C2.3.7.1. The expected consequences for HD 1.2 AE are similar to those for HD 1.1.
The effects of HD 1.2 AE are NEW dependent.

C2.3.7.2. The principal hazard to personnel in the open, to aircraft, and to occupied
vehicles is fragments.

C2.3.7.3. Airblast, fragment, and thermal hazards to buildings and parked aircraft or
vehicles cannot be predicted reliably because the effects will depend on the MCE.

C2.4. HD 1.3 EFECTS

C2.4.1. Gas Pressures. In an incident involving only HD 1.3 or HD 1.3 with HD 1.4 (a HD
1.3 event):

C2.4.1.1. Where sufficient venting is provided, gas pressures generated by the event are
not a significant concern. Examples of sites with sufficient venting include open storage and
structures where internal pressures do not exceed 1-2 psi [6.9-13.8 kPa] (non-confinement
structure).

C2.4.1.2. Where venting is insufficient, internal gas pressures may be substantial.

In such situations, these pressures may blow out vent panels or frangible walls and, in some
instances, cause partial or complete structural failure.

34 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.4.1.3. Where there is minimal venting and structural containment (extreme

confinement), a detonation of the HD 1.3 may occur with effects similar to those of a HD 1.1
explosion. For example, HD 1.3 AE is considered as HD 1.1 (mass explosion) for QD purposes
when stored in underground chambers.

C2.4.2. Fragments. In an HD 1.3 event, fragments are considerably less hazardous than
those produced by HD 1.1 and HD 1.2 events. Internal gas pressures may produce fragments
from the bursting of containers or the rupture of containment facilities. In general, such
fragments will be large and of low velocity. (For exceptions, see subparagraph C2.4.1.3.)

C2.4.3. Thermal Hazards. In an HD 1.3 event, heat flux presents the greatest hazard to
personnel and assets. Energetic materials in HD 1.3 articles include both fuel components and
oxidizers. Burning these materials emits fuel-rich flammable gases, fine particles, or both. This
unburned material may ignite when it comes in contact with air and cause a large fireball. This
fireball will expand radially from the ignition site and could wrap around obstacles, even those
designed to provide line-of-sight protection from HD 1.1 events. Shields and walls can be
designed to provide protection from thermal effects (see Chapter 4).

C2.4.3.1. The nominal spherical fireball that would be expected from the rapid burning
of HD 1.3 can be calculated by DFIRE = 10 x WEFF1/3 where “DFIRE” is the diameter of the
fireball (ft) and “WEFF” is the quantity of HD 1.3 involved (lb), multiplied by a 20 percent safety
factor (e.g., “W” of 100 pounds = “WEFF”of 120 pounds) [DFIRE (meters) = 3.97 x WEFF
(kilograms) 1/3].

C2.4.3.2. In addition to the fireball itself, the thermal flux from the fireball can ignite
fires out to Intermagazine Distance (IMD).

C2.4.4. Propelled Items. In an HD 1.3 event, some AE or AE components may become

propulsive and travel well beyond IBD.

C2.4.5. Firebrands. In an HD 1.3 event, a severe fire-spread hazard may result from
firebrands projected from the incident site. Firebrands can be expected to be thrown more than
50 ft [15.2 m] from a HD 1.3 event. Firebrands can ignite fires well beyond the distance to
which a fireball poses a threat.

C2.4.6. Expected Consequences

C2.4.6.1. Exposed personnel may receive severe burns from fireballs or flash burning in
an HD 1.3 event. The hazard distance is dependent on the quantity and burning rate of the HD
1.3 involved.

C2.4.6.2. Buildings, vehicles, and aircraft may be ignited by radiant heat, sparks, or
firebrands or may be damaged by heat (searing, buckling, etc.).

35 CHAPTER 2
DoD 6055.09-STD, February 29, 2008

C2.4.6.3. Personnel in nearby buildings, vehicles, or aircraft may be injured unless

evacuated before heat conditions reach hazardous levels.

C2.5. HD 1.4 EFFECTS

C2.5.1. Blast. There is no blast associated with an incident involving only HD 1.4
(an HD 1.4 event).

C2.5.2. Fragmentation. An HD 1.4 event will not produce fragments of appreciable energy
(i.e., greater than 14.8 ft-lbs [20 joules]). Fragments from HD 1.4S have energies less than or
equal to 5.9 ft-lbs [8 joules].

C2.5.3. Thermal Hazard. AE given this designation are considered to provide only a
moderate fire hazard. A fireball or jet of flame may extend 3 feet [1 m] beyond the location of
the HD 1.4 event. A burning time of less than 330 seconds (5.5 minutes) for 220 lbs [100 kg] of
the HD 1.4 AE is expected.

C2.5.4. Firebrands. No fiery projections are expected beyond 50 feet [15.2 m].

C2.5.5. Compatibility Group (CG) -S Items. HD 1.4 AE assigned a CG-S designation (see
subparagraph C3.2.2.1.13.) is the most benign of all AE. In an HD 1.4 event that only involves
CG-S, the expected blast, thermal, and projection effects will not significantly hinder fire
fighting or other emergency responses.

C2.5.6. Expected Consequences. There may be minor consequences (projection, fire,

smoke, heat, or loud noise) beyond the AE itself.

C2.6. HD 1.5 EFFECTS

HD 1.5 effects are similar to those produced by HD 1.1, without the fragmentation effects.

C2.7. HD 1.6 EFFECTS

HD 1.6 effects are similar to those produced by HD 1.3.

C3. CHAPTER 3
HAZARD CLASSIFICATION,
STORAGE AND COMPATIBILITY PRINCIPLES,
AND MIXING RULES

C3.1. HAZARD CLASSIFICATION

To ease identification of hazard characteristics for storage and transportation, the Department of
Defense shall use:

C3.1.1. DoD Ammunition and Explosives Hazard Classification Procedures as a basis for
assigning hazard classifications to all AE for both storage and transportation applications. (See
Technical Bulletin (TB) 700-2, Naval Sea Systems Command Instruction (NAVSEAINST)
8020.8B, Technical Order (TO) 11A-1-47, Defense Logistics Agency Regulation (DLAR)
8220.1 (Reference (d)).

C3.1.2. The applicable Department of Transportation (DoT) hazardous materials regulations

per 49 Code of Federal Regulations (CFR) parts 171 to 177 (Reference (e)).

C3.1.3. The United Nations’ (UN) international system of classification developed for the
transport of dangerous goods. See ST/SG/AC.10 (Reference (f)).

C3.2. DOD HAZARD CLASSIFICATION SYSTEM

C3.2.1. The DoD hazard classification system consists of nine hazard classes plus a non-
regulated category that applies when explosives and hazardous materials are present in an item,
but not to the degree that criteria for assignment to one of the nine classes are met. AE is
assigned to the class that represents an item’s predominant hazard characteristic. Class 1 applies
to AE where the explosive hazard predominates. The six Class 1 divisions, and three division
1.2 subdivisions (subdivisions are only applicable for storage applications), which are outlined
below, are used to indicate the character and predominance of explosive hazards. In addition to
the classes, divisions, subdivisions, and the non-regulated category, thirteen Compatibility
Groups (CG) are used for segregating AE on the basis of similarity of function, features, and
accident effects potential. Furthermore, a parenthetical number is also used to indicate the
minimum separation distance (in hundreds of feet) for protection from debris, fragments, and
firebrands, when distance alone is relied on for such protection. This number is placed to the left
of the hazard classification designators 1.1 through 1.3 (e.g., (18)1.1, (08)1.2.3, or (02)1.3). To
simply express an item’s hazard classification, this Standard uses the term “Hazard Division
(HD)” to avoid repeatedly using the more cumbersome terminology “Subdivision X of Division
Y of Class Z.” The six Class 1 divisions and three hazard subdivisions are:

C3.2.1.1. Mass explosion (HD 1.1).

C3.2.1.2. Non-mass explosion, fragment producing (HD 1.2). (See paragraph C9.4.2.)

37 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

C3.2.1.2.1. HD 1.2.1. Those items with a NEWQD > 1.60 pounds [0.73 kg] or that
exhibit fragmentation characteristics similar to or greater than (higher density, longer distance)
M1 105 mm projectiles regardless of NEWQD.

C3.2.1.2.2. HD 1.2.2. Those items with an NEWQD < 1.60 pounds [0.73 kg] or that
at most exhibit fragmentation characteristics similar to high-explosive 40 mm ammunition
regardless of NEWQD.

C3.2.1.2.3. HD 1.2.3. AE that exhibits at most an explosion reaction in the

sympathetic reaction test, and no reaction more severe than burning in the liquid fuel/external
fire test, bullet impact test, and slow heating test.

C3.2.1.3. Mass fire, minor blast or fragment (HD 1.3).

C3.2.1.4. Moderate fire, no significant blast or fragment (HD 1.4).

C3.2.1.5. Explosive substance, very insensitive (with mass explosion hazard) (HD 1.5).

C3.2.1.6. Explosive article, extremely insensitive (no mass explosion hazard) (HD 1.6).

C3.2.2. Storage and Transportation CG

C3.2.2.1. The thirteen CG assigned to AE based on similarity of function, features, and

accident effects potential are:

C3.2.2.1.1. Group A. Initiating (primary) explosives. Bulk initiating explosives that

have the necessary sensitivity to heat, friction, or percussion to make them suitable for use as
initiating elements in an explosive train. Examples include the following: bulk lead azide, lead
styphnate, mercury fulminate, tetracene, dry cyclotrimethylenetrinitramine (RDX) (also known
as cyclonite, hexogen, or Royal Demolition Explosive), and dry pentaerythritol tetranitrate
(PETN).

C3.2.2.1.2. Group B. Detonators and similar initiating devices not containing two or
more effective protective features. Items containing initiating (primary) explosives that are
designed to initiate or continue the functioning of an explosive train. Examples include the
following: detonators, blasting caps, small arms primers, and fuzes.

C3.2.2.1.3. Group C. Bulk propellants, propelling charges, and devices containing

propellant with, or without, its own means of ignition. Examples include the following: bulk
single-, double-, or triple-base, and composite propellants, rocket motors (solid propellant), and
propelled AE with inert projectiles.

C3.2.2.1.4. Group D. Bulk black powder; bulk HE (secondary explosives); and AE

without a propelling charge, but containing HE (secondary explosives) without its own means of
initiation, i.e., no initiating device is present or the device has two or more effective protective
features. Examples include the following: bulk trinitrotoluene (TNT), Composition B, and black

38 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

powder; bulk wet RDX or PETN; bombs, projectiles, Cluster Bomb Units (CBU), depth charges,
and torpedo warheads.

C3.2.2.1.5. Group E. AE containing HE (secondary explosives) without its own

means of initiation and either containing, or with, a solid propelling charge. Examples include
the following: artillery AE, rockets, and guided missiles.

C3.2.2.1.6. Group F. AE containing HE (secondary explosives) with its own means

of initiation, i.e., the initiating device present has less than two effective protective features, and
with or without a solid propelling charge. Examples include the following: grenades, sounding
devices, and similar items having explosive trains with less than two effective protective
features.

C3.2.2.1.7. Group G. Illuminating, incendiary, and smoke- (including

hexachlorethane (HC)) or tear-producing AE, excluding those that are water-activated or that
contain white phosphorus (WP) or a flammable liquid or gel. Examples include the following:
flares, signals, and pyrotechnic substances.

C3.2.2.1.8. Group H. AE containing WP. AE in this group contains fillers that are
spontaneously flammable when exposed to the atmosphere. Examples include the following:
WP and plasticized white phosphorus (PWP).

C3.2.2.1.9. Group J. AE containing flammable liquids or gels other than those that
are spontaneously flammable when exposed to water or the atmosphere. Examples include the
following: liquid- or gel-filled incendiary AE, Fuel-Air Explosive (FAE) devices, and
flammable liquid-fueled missiles and torpedoes.

C3.2.2.1.10. Group K. AE containing toxic chemical agents. AE in this group

contain chemicals specifically designed for incapacitating effects more severe than lachrymation
(tear-producing). Examples include the following: artillery or mortar AE (fuzed or unfuzed),
grenades, rockets and bombs filled with a lethal or incapacitating chemical agent. (See note 4,
Table C3.T1.)

C3.2.2.1.11. Group L. AE not included in other CG, having characteristics that

present a special risk that does not permit storage with other types of AE, or other kinds of
explosives, or dissimilar AE of this group. Examples include the following: water-activated
devices, pyrophorics and phosphides and devices containing these substances, prepackaged
hypergolic liquid-fueled rocket engines, triethyl aluminum (TEA), thickened TEA (TPA), and
damaged or suspect AE of any group. Different types of AE in CGL presenting similar hazards
may be stored together.

C3.2.2.1.12. Group N. AE containing only Extremely Insensitive Detonating

Substances (EIDS). An example is HD 1.6 AE.

C3.2.2.1.13. Group S. AE that presents no significant hazard, packaged or designed

so that any hazardous effects from accidental functioning are limited to the extent that they do

39 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

not significantly hinder firefighting. Examples include the following: explosive switches or
valves and small arms ammunition.

C3.2.3. Sensitivity Groups (SG). For the purpose of storage within a HPM (see paragraph
C3.3.7.) or where ARMCO, Inc. revetments (see paragraph C5.3.5.) or Substantial Dividing
Walls (SDW) are utilized to reduce MCE, each HD 1.1 and HD 1.2 AE item is designated, based
on its physical attributes, into one of five SG. Directed energy weapons are further identified by
assigning the suffix “D” following the SG designation (e.g., SG2D). The SG assigned to an HD
1.1 and HD 1.2 AE item is found in the Joint Hazard Classification System (JHCS).

C3.2.3.1. The five SG, in relative order from least sensitive to most sensitive, are:

C3.2.3.1.1. SG 2: Non-robust or thin-skinned AE (see glossary).

C3.2.3.1.2. SG 1: Robust or thick-skinned AE. A SG 1 item meets any two of the

following criteria:

C3.2.3.1.2.1. Ratio of explosive weight to empty case weight < 1.

C3.2.3.1.2.2. Minimum case thickness > 0.4 inches [1 cm].

C3.2.3.1.2.3. Ratio of case thickness to NEWQD1/3 > 0.05 in/lb1/3 [0.165

cm/kg1/3].

C3.2.3.1.3. SG 3: Fragmenting AE. These items, which are typically air-to-air

missiles, have warhead cases designed for specific fragmentation (e.g., pre-formed fragment
warhead, scored cases, and continuous rod warheads).

C3.2.3.1.4. SG 4: Cluster bombs/dispenser munitions.

C3.2.3.1.5. SG 5: Other AE (items for which HPM non-propagation walls are not
effective). Items are assigned to SG 5 because they are either very sensitive to propagation or
their sensitivity has not been determined.

C3.2.3.2. Item-specific testing or analyses can be used to change an item’s SG.

C3.3. STORAGE AND COMPATIBILITY PRINCIPLES

C3.3.1. Separate storage of AE by HD and type provides the highest degree of safety.
Because such storage is generally not feasible, mixed storage—subject to compliance with these
Standards—is normally implemented when such storage facilitates safe operation and promotes
overall storage efficiency.

40 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

C3.3.2. The CG assigned to AE indicates what it can be stored with or without significantly
increasing either an accident’s probability or, for a given quantity, the magnitude of an accident’s
effects. Only compatible AE will be stored together.

C3.3.3. AE may not be stored with dissimilar substances or articles (e.g., flammable or
combustible materials, acids, or corrosives) that may present additional hazards to the AE unless
they have been assessed to be compatible. Non-Regulated AE and AE assigned to Classes 2
through 9 may have a CG assigned. When so assigned, the AE may be stored in an explosives
magazine in accordance with the CG. The explosive weight of non-regulated AE and AE
assigned to Classes 2 through 9 is not considered for QD purposes.

C3.3.4. The DoD hazard classification system classifies articles that contain riot control
substances, without explosives components, and bulk toxic chemical agents as HD 6.1.

C3.3.5. AE in damaged packaging, in a suspect condition, or with characteristics that

increase risk in storage, are not compatible with other AE and will be stored separately (in CG
L).

C3.3.6. If different types of CG N munitions are mixed together and have not been tested to
ensure non-propagation, the mixed munition types are individually considered to be HD 1.2.1 D
or HD 1.2.2 D based on their NEWQD or overriding fragmentation characteristics.

C3.3.7. High Performance Magazine. Because of its construction (see paragraph C5.2.4.),
each HPM storage cell is treated as a separate magazine for the purposes of meeting
compatibility and mixing requirements. Within a HPM cell, all current compatibility and mixing
regulations apply. The maximum allowable NEWQD is 30,000 lbs [13,608 kg] in a HPM cell
and 60,000 lbs [27,215 kg] in the loading dock with the following restraints:

C3.3.7.1. When SG 1, 2, or 3 AE is present in a HPM cell, the allowable NEWQD in all

cells (adjacent, across, and diagonal) and in the loading dock remains the maximum.

C3.3.7.2. When SG 4 AE is present in a HPM cell, the allowable NEWQD in each

adjacent cell and in the cell directly across from it is reduced to 15,000 lbs [6,804 kg]. The
allowable NEWQD in diagonal cells and in the loading dock remains the maximum.

C3.3.7.3. When SG 5 AE is present in a HPM, the NEWQD of all cells and the loading
dock must be summed for quantity-distance purposes.

C3.3.7.4. When directed energy weapons are present in a HPM, they must be oriented in
such a manner that if initiation were to occur, the consequences would be directed away from
any other cell. Otherwise, the NEWQD of all cells and the loading dock must be summed for
quantity-distance purposes.

C3.3.7.5. When HD and SG are mixed within a HPM cell, the most sensitive SG
associated with the AE in that cell controls the allowable NEWQD in each adjacent cell. For

41 CHAPTER 3
DoD 6055.09-STD, February 29, 2008

example, when HD 1.3, HD 1.4 and HD 1.6 items are stored with HD 1.1 or HD 1.2 items, the
most sensitive SG of the HD 1.1 and HD 1.2 items controls the storage requirements.

C3.4. MIXED COMPATIBILITY GROUP STORAGE

C3.4.1. AE of different CG may only be mixed in storage as indicated in Table C3.T1. The
exceptions are when Chapter 10 is being applied, and at specific continental United States
(CONUS) locations that a DoD Component designates to store AE packaged and configured for
rapid response (e.g., Rapid Deployment Force) for which the DDESB has approved the site plan.
Such designated locations are authorized to mix CG, without complying with the compatibility
and mixing requirements, as operationally required to achieve the optimum load needed by the
intended receiving troops. The MCE allowable at any of these storage sites shall be limited to
8,818 lbs NEWQD [4,000 kg NEQ]. When computing QD requirements for such sites, Chapter
9 applies. However, the following AE will be excluded for NEWQD determination at such
storage sites:

C3.4.1.1. Propelling charges in HD 1.2 fixed, semi-fixed, mortar, and rocket AE (see
glossary).

C3.4.1.2. The NEWQD of HD 1.3 items, except at sites that contain only HD 1.3 items.
At such sites, HD 1.3 QD applies. (NOTE: In the application of this paragraph to separate
loading AE, the explosive weight of propelling charges is generally excluded when matched
pairs of projectiles and propelling charges are at the site. However, if the quantity of propelling
charges at the site exceeds the maximum usable for the quantity of projectiles at the site, the
explosive weights of all propelling charges and projectiles at the site must be summed for
NEWQD determination.)

Notes for Table C3.T1.:
1 An “X” at an intersection indicates that the groups may be combined in storage. Otherwise, mixing is either
prohibited or restricted per Note 2.
2 A “Z” at an intersection indicates that when warranted by operational considerations or magazine non-
availability, and when safety is not sacrificed, mixed storage of limited quantities of some items from
different groups may be approved by the DoD Components. Such approval documentation must be kept on
site. Component approval of mixed storage in compliance with Z intersections does not require a waiver or
exemption. Mixed storage of items within groups where no X or Z exists at that pair’s intersection beyond
the prohibitions and limitations of Note 7, however, requires an approved waiver or exemption.
Examples of acceptable storage combinations are:
a. HD 1.1A initiating explosives with HD 1.1B fuzes not containing two or more effective protective
features.
b. HD 1.3C bulk propellants or bagged propelling charges with HD 1.3G pyrotechnic substances.
3 Equal numbers of separately packaged components of hazard-classified complete rounds of any single type
of AE may be stored together. When so stored, compatibility is that of the complete round.
4 CG K requires not only separate storage from other groups, but also may require separate storage within the
group. The controlling DoD Component will determine which items under CG K may be stored together
and those that must be stored separately. Such documentation must be kept on site.
5 AE classed outside Class 1 may be assigned the same CG as Class 1 AE containing similar hazard features,
but where the explosive hazard predominates. Non-Class 1 AE and Class 1 AE assigned the same CG may
be stored together.
6 The DoD Components may authorize AE-designated “Practice” or “Training” by nomenclature, regardless
of the CG assigned, to be stored with the tactical AE it simulates. Such documentation must be kept on site.
7 The DoD Components may authorize the mixing of CG, except items in CG A, K and L, in limited
quantities generally of 1,000 lb [454 kg] total NEWQD or less. Such documentation must be kept on site.
8 For purposes of mixing, all AE must be packaged in its standard storage and shipping container. AE
containers will not be opened for issuing items from storage locations. Outer containers may be opened in
storage locations for inventorying and for magazines storing only HD 1.4 items, unpacking, inspecting, and
repackaging the HD 1.4 ammunition.
9 When using the “Z” mixing authorized by Note 2 for articles of either CG B or CG F, each will be
segregated in storage from articles of other CG by means that prevent propagation of CG B or CG F articles
to articles of other CG.
10 If dissimilar HD 1.6N AE are mixed together and have not been tested to ensure non-propagation, the mixed
AE are individually considered to be HD 1.2.1 D or HD 1.2.2 D based on their NEWQD or overriding
fragmentation characteristics for purposes of transportation and storage. When mixing CG N AE with CG
B through CG G or with CG S, see subparagraphs C9.2.2.1.1., C9.2.2.4., C9.2.2.10., and C9.2.2.11. to
determine the HD for the mixture.

DoD 6055.09-STD, February 29, 2008

C4. CHAPTER 4
PERSONNEL PROTECTION

C4.1. SCOPE AND APPLICATION

This chapter establishes blast, fragment, and thermal hazards protection principles. It applies to
all operations and facilities within an Explosives Safety Quantity-Distance (ESQD) arc in which
personnel are exposed to AE hazards. Technical Manual (TM)-5-1300, Naval Facilities
Engineering Command (NAVFAC) P-397, Air Force Manual (AFM) 88-22 (Reference (g))
contains design procedures to achieve personnel protection, protect facilities and equipment, and
prevent propagation of explosions.

C4.2. RISK ASSESSMENT

The responsible DoD Component shall perform a risk assessment on new or modified operations
and facilities involving AE. Based upon such an assessment, engineering design criteria for
facilities and operations shall be developed for use in the selection of equipment, shielding,
engineering controls, and protective clothing for personnel.

C4.2.1. The risk assessment shall include:

C4.2.1.1. Initiation sensitivity.

C4.2.1.2. Quantity of materials.

C4.2.1.3. Heat output.

C4.2.1.4. Rate of burn.

C4.2.1.5. Potential ignition and initiation sources.

C4.2.1.6. Protection capabilities of shields, various types of clothing, and fire protection
systems.

C4.2.1.7. Personnel exposure.

C4.2.2. New or modified facilities, located within the IBD arc of any PES, that will include
glass panels and will contain personnel, shall have a glass breakage personnel hazards risk
assessment conducted.

C4.3. PERMISSIBLE EXPOSURES

C4.3.1. Accidental Ignition or Initiation of Explosives.

43 CHAPTER 4
DoD 6055.09-STD, February 29, 2008

C4.3.1.1. When a risk assessment indicates that there is an unacceptable risk from an
accidental explosion or a flash fire, personnel shall be provided protection from blast, fragments,
and thermal effects, to include respiratory and circulatory hazards.

C4.3.1.2. When required, personnel protection must limit incident blast overpressure to
2.3 psi [15.9 kPa], fragments to energies of less than 58 ft-lb [79 joules], and thermal fluxes to
0.3 calories per square centimeter per second [12.56 kilowatts per square meter].

C4.3.1.3. K24 [9.52] distance provides the required level of protection for blast and
thermal effects only.

C4.3.1.4. Shields that comply with Military Standard (MIL-STD)-398 (Reference (h))
provide acceptable protection for blast, thermal and fragment effects.

C4.3.2. Intentional Ignition or Initiation of AE. At operations (e.g., function, proof, lot
acceptance testing) where intentional ignition or initiation of AE are conducted and where
shielding is required, as determined on a case-by-case basis by the DoD Component concerned,
personnel protection shall:

C4.3.2.1. Meet the requirements of subparagraph C4.3.1.2.

C4.3.2.2. Limit overpressure levels in personnel-occupied areas to satisfy MIL-STD-

1474D (Reference (i)).

C4.3.2.3. Contain or defeat all fragments.

C4.3.2.4. Limit thermal flux to: “Q” (calories/square centimeter/second) = 0.62t-0.7423

where “t” is the time in seconds that a person is exposed to the radiant heat. (Shields that comply
with Reference (h) provide acceptable protection.)

C4.4. PROTECTIVE MEASURES

Personnel protection may be achieved by:

C4.4.1. Eliminating or establishing positive control of ignition and initiation stimuli.

C4.4.2. Using sufficient distance or barricades to protect from blast or fragments.

C4.4.3. Using fire detection and extinguishing systems (e.g., infra-red (IR) actuated deluge
system) in those areas where exposed, thermally-energetic materials that have a high probability
of ignition and a large thermal output are handled. Such systems shall maximize the speed of
detection, have adequate capacity to extinguish potential flash fires in their incipient state, and
maximize the speed of the application of the extinguishing agent.

44 CHAPTER 4
DoD 6055.09-STD, February 29, 2008

C4.4.4. Using thermal shielding between the thermal source and personnel in AE operational
areas, where it is essential for personnel to be present and the risk assessment indicates that an
in-process thermal hazard exists. Any shielding used shall comply with Reference (h). When
shielding is either not possible or inadequate, to include a failure to protect exposed personnel’s
respiratory and circulatory systems, augmentation with improved facility engineering design and
personnel protective clothing and equipment may be necessary.

C4.4.5. Using thermal protective clothing that is capable of limiting bodily injury to first
degree burns (0.3 calories per square centimeter per second [12.56 kilowatts/m2]) with personnel
taking turning-evasive action, when the maximum quantity of combustible material used in the
operation is ignited.

C4.4.6. Using protective clothing capable of providing respiratory protection from the
inhalation of hot vapors or any toxicological effects, when the risk assessment indicates adverse
effects would be encountered from the inhalation of combustion products.

C4.4.7. Minimizing the number and size of glass panels in an ES and, if possible, orienting
the ES to minimize blast loads on glass panels, when a risk assessment (see section C4.2.)
indicates that a glass hazard is present.

C4.4.7.1. When use of window panels is determined to be necessary and a risk

assessment determines that there will be an associated glass hazard, blast-resistant windows of
sufficient strength, as determined by an engineering analysis, shall be used for:

C4.4.7.1.1. Existing ES, upon major modification or modified operations.

C4.4.7.1.2. New construction. (The use of glass panels in new construction should
be avoided.)

C4.4.7.2. The framing and sash of such panels shall be of sufficient strength to retain the
panel in the structure for the expected blast loads from an explosion at any PES.

DoD 6055.09-STD, February 29, 2008

C5. CHAPTER 5
CONSTRUCTION CRITERIA PERMITTING REDUCED SEPARATION DISTANCES

C5.1. GENERAL

C5.1.1. This chapter contains DoD standards for construction of ECM, barricades,
barricaded open storage modules, special structures, ARMCO, Inc. revetments, and underground
storage facilities. Facilities constructed per this chapter:

C5.1.1.1. Are permitted to use reduced separation distance criteria.

C5.1.1.2. Must meet the criteria of Chapters 6 and 7.

C5.1.2. Construction features and location are important safety considerations in planning
facilities. The effects of potential explosions may be altered significantly by construction
features that limit the amount of explosives involved, attenuate blast overpressure or thermal
radiation, and reduce the quantity and range of hazardous fragments and debris. (NOTE: Proper
location of ES in relation to PES helps minimize unacceptable damage and injuries in the event
of an incident.) The major objectives in facility planning shall be to:

C5.1.2.1. Protect against explosion propagation between adjacent bays or buildings and
protect personnel against death or serious injury from incidents in adjacent bays or buildings.
The construction of separate buildings to limit explosion propagation, rather than the use of
either protective construction or separation of explosives within a single building should be
considered when safety would be greatly enhanced or cost would be significantly reduced.

C5.1.2.2. Protect assets, when warranted.

C5.1.3. Hardening an ES or constructing a PES to suppress explosion effects to provide an

appropriate degree of protection may allow a reduction of the separation distances required by
QD tables. The rationale and supporting data that justify any such QD reduction shall be
submitted to the DDESB with the site and general construction plans for approval (see section
C5.4.).

C5.1.4. New construction of previously DDESB-approved 7-Bar and 3-Bar ECM must meet
the minimum requirements of the current revisions of the approved drawings.

C5.2. AE STORAGE FACILITIES

C5.2.1. ECM. An ECM’s primary purpose is to protect AE. To qualify for the default IMD
in Table C9.T6., an ECM, acting as an ES, must not collapse. Although substantial permanent
deformation of the ECM may occur, sufficient space should be provided to prevent the deformed
structure or its doors from striking the contents.

46 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.1.1. ECM may be approved for storage of up to 500,000 lbs NEW [226,795 kg
NEQ] of HD 1.1 in accordance with Table C9.T5. DDESB Technical Paper (TP) No. 15,
(Reference (j)) provides listings of the various types of ECM that have been constructed. These
magazines are identified by their structural strength designator (i.e. 7-Bar, 3-Bar, or Undefined).
Table AP1-1. of Reference (j) lists the 7-Bar and 3-Bar ECM designs that are currently approved
for new construction.

C5.2.1.1.1. If an ECM’s drawing number(s) are not listed in Reference (j), it shall be
treated as an “Undefined” ECM, until a structural analysis is performed to show that the ECM
qualifies for another structural strength designation, or support documentation is provided to
prove the ECM had been approved by the DDESB with a different structural strength
designation.

C5.2.1.1.2. For existing, arch-shaped Undefined ECM, U. S. Army Corps of

Engineers (CoE) Report HNDED-CS-S-95-01 (Reference (k)) may be used to determine if an
Undefined ECM could qualify as a 7-Bar or a 3-Bar ECM.

C5.2.1.1.3. DDESB approval is required prior to any change in an ECM’s structural

strength designator.

C5.2.1.1.4. Certain ECM, aboveground storage magazines, and containers have been
approved with reduced NEW and/or reduced QD and these are listed in Table AP1-4. of
Reference (j). Use of these structures/containers requires that their use and siting meet all
conditions AND restrictions specified in the design and approval documentation, as described in
Reference (j).

C5.2.1.2. ECM must be designed to withstand the following:

C5.2.1.2.1. Conventional (e.g., live, dead, snow) loads for the barrel of an
arch-shaped ECM.

C5.2.1.2.2. Conventional (e.g., live, dead, snow) and blast-induced loads for the roof
of a flat-roofed ECM.

C5.2.1.2.3. Conventional (e.g., live, dead, snow) loads for the rear wall of an
arch-shaped ECM and for the rear and side walls of a flat-roofed ECM.

C5.2.1.2.4. Expected blast loads, as applicable:

C5.2.1.2.4.1. On the head wall and door of 3-Bar ES ECM is a triangular pulse
with peak overpressure of 43.5 psi [3 bars, 300 kPa] and impulse of 11.3W1/3 psi-ms [100Q1/3
Pa-s].

C5.2.1.2.4.2. On the head wall and door of 7-Bar ES ECM is a triangular pulse
with peak overpressure of 101.5 psi [7 bars, 700 kPa] and impulse of 13.9W1/3 psi-ms [123Q1/3
Pa-s].

47 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.1.2.4.3. On the roof of a flat-roofed Undefined, 3-Bar, or 7-Bar ES ECM is

a triangular pulse with peak overpressure of 108 psi [7.5 bars, 745 kPa] and impulse of 19W1/3
psi-ms [170Q1/3 Pa-s].

C5.2.1.3. Earth cover for ECM.

C5.2.1.3.1. Earth cover shall be reasonably cohesive and free from harmful (toxic)
matter, trash, debris, and stones heavier than ten pounds [4.54 kg] or larger than six inches [152
mm] in diameter. Solid or wet clay or similar types of soil shall not be used as earth cover
because it is too cohesive. The larger of acceptable stones shall be limited to the lower center of
fills and shall not be used for earth cover over magazines. The earthen material shall be
compacted and prepared, as necessary, for structural integrity and erosion control. If it is
impossible to use a cohesive material (e.g., in sandy soil), the earth cover over ECM shall be
finished with a suitable material (e.g., geotextiles, gunnite) that will ensure structural integrity.

C5.2.1.3.2. The earth fill or earth cover between ECM may be either solid or sloped.
A minimum of 2 ft [0.61 m] of earth cover shall be maintained over the top of each ECM. If the
specified thickness and slope of earth on the ECM is not maintained, the ECM shall be sited as
an AGM.

C5.2.2. Barricaded Open Storage Modules

C5.2.2.1. As depicted in Figure C5.F1., a module is a barricaded area composed of a

series of connected cells with hard surface (e.g., concrete, packed earth, engineered
materials, etc.) storage pads separated from each other by barricades. Although a light metal
shed or other lightweight fire retardant cover may be used for weather protection for individual
cells, heavy structures (e.g., reinforced concrete, dense masonry units), or flammable material
shall not be used.

C5.2.2.2. The maximum NEW [NEQ] permitted to be stored within each cell is 250,000
lbs [113,398 kg].

C5.2.2.3. Module storage is considered a temporary expedient and may be used as the
DoD Component concerned determines necessary. However, from an explosives safety and
reliability standpoint, priority shall be given to the use of ECM for items requiring protection
from the elements, long-term storage, or high security protection.

C5.2.2.4. Storage shall be limited to AE that will not promptly propagate explosions or
mass fire between modules, and that are not susceptible to firebrands and fireballs. These
restrictions allow storage at K1.1 [0.44] separation.

C5.2.2.4.1. Only the following AE are approved for modular storage:

C5.2.2.4.1.1. Robust HD 1.1 AE (e.g., HE bombs, fuzed or unfuzed, with or

without fins) when stored on nonflammable pallets.

48 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.2.4.1.2. The below items when contained in nonflammable shipping

containers:

C5.2.2.4.1.2.1. 30 mm and smaller AE.

C5.2.2.4.1.2.2. CBU.

C5.2.2.4.1.2.3. Inert AE components.

C5.2.2.4.1.2.4. HD 1.4 AE.

C5.2.2.4.2. Module storage of AE items in flammable outer-packaging

configurations shall be minimized. AE items in flammable outer-packaging configurations must
be covered with fire retardant material. Combustible dunnage or other flammable material shall
not be stored either in, or within, 100 ft [30.5 m] of modules.

C5.2.2.4.3. When fire retardant materials are used to cover AE items stored in
modules, ventilation shall be provided between the covers and the stored AE items to minimize
the effects of solar heating upon the stored AE.

C5.2.2.4.4. AE stored in each module shall normally be limited to one type of item,
unless the DoD Component concerned authorizes mixed storage.

C5.2.2.5. Barricade Requirements:

C5.2.2.5.1. All barricades used in forming the module shall meet the requirements in
section C5.3. The width or length of the stack of AE (controlled by the pad size of the cell) and
the distances between the stack and the top of the barricade influences the minimum barricade
height requirement. The heights listed in Table C5.T1. are the minimum requirements for
barricade locations. These minimum heights are based upon both the storage pad sizes and the
separations shown. When feasible, barricade heights should be increased (see subparagraph
C5.3.2.3.).

C5.2.2.5.2. The centerlines of barricades between cells of the module shall be located
at a point halfway between adjacent AE storage pads. Back and end (outside) barricades shall be
located at the same distance from the pads as those between the cells.

C5.2.2.5.3. When selecting a site for a module, maximum advantage should be taken
of natural topographical barriers. When used, natural barriers shall provide the same level of
protection as the barricade shown in Figure C5.F1.

C5.2.2.6. Table C5.T1. provides the minimum pad sizes necessary to store the NEWQD
indicated. The pad’s size may need to be adjusted to accommodate specific AE. This
adjustment will impact the required barricade height (see Note 2 of Table C5.T1.).

49 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.2.7. The only restriction on the arrangement of cells within a module and of groups
of modules is that cell openings may not face each other, unless they are either barricaded or
meet QD criteria for an unbarricaded AGM (see Table C9.T6.).

C5.2.3. Underground Storage Facilities

C5.2.3.1. General Design Considerations

C5.2.3.1.1. Underground storage facilities may consist of a single chamber or a series

of connected chambers and other protective construction features. The chambers may be either
excavated or natural geological cavities. Figure C5.F2. shows the layout of several typical
underground facilities. To qualify as an underground facility, the minimum distance from the
perimeter of a storage area to an exterior surface shall be greater than 0.25 W1/3 [0.10 Q1/3]. This
minimum distance normally, but not always, equals the thickness of the earth cover. If this
criterion cannot be met, the facility must be sited as an AGM.

C5.2.3.1.2. Design of new underground storage facilities must take into account site
conditions, storage requirements, and operational needs. Once these are established, a design
may be developed based on the CoE definitive drawing, DEF 421-80-04, discussed in Chapter 5
of Reference (j). Special features (e.g., debris traps, expansion chambers, closure blocks, portal
barricades, and constrictions) may be incorporated in the design of underground storage facilities
to reduce the IBD for both debris and airblast. The specifications for these special features are
also given in CoE definitive drawing, DEF 421-80-04, and their effects are discussed below.

C5.2.3.2. Special Design Considerations

C5.2.3.2.1. Debris Mitigation. Debris IBD may be reduced through the use of debris
traps, expansion chambers, high pressure closures, and portal barricades.

C5.2.3.2.1.1. Debris traps are pockets excavated in the rock at or beyond the end
of sections of tunnel that are designed to catch debris from a storage chamber detonation. Debris
traps should be at least 20 percent wider and 10 percent taller than the tunnel leading to the trap,
with a depth (measured along the shortest wall) of at least one tunnel diameter.

C5.2.3.2.1.2. Expansion chambers are very effective in entrapping debris, as long

as the tunnels entering and exiting the chambers are either offset in axial alignment by at least
two tunnel widths, or enter and exit the chambers in directions that differ by at least 45 degrees.

53 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.3.2.1.3. To be effective, debris traps and expansion chambers that are

intended to entrap debris must be designed to contain the full potential volume of debris, based
on the maximum capacity of the largest storage chamber.

C5.2.3.2.1.4. Portal barricades provide a means of reducing IBD from debris by

obstructing the path of the debris as it exits the tunnel.

C5.2.3.2.1.5. High-pressure closures are large blocks constructed of concrete or

other materials that can obstruct or greatly reduce the flow of blast effects and debris from an
explosion from or into a storage chamber. For chamber loading density (w) of about 0.625 lb/ft3
[10 kg/m3] or above, closure blocks will contain 40 percent or more of the explosion debris
within the detonation chamber, provided that the block is designed to remain intact. If a closure
block fails under the blast load, it will produce a volume of debris in addition to that from the
chamber itself. However, because the block’s mass and inertia are sufficient to greatly reduce
the velocity of the primary debris, the effectiveness of other debris-mitigating features (e.g.,
debris traps, expansion chambers, and barricades) is increased.

C5.2.3.2.1.6. Use of barricades with any other of these features will lower the
debris hazard to a level where QD considerations for debris is not required.

C5.2.3.3. Airblast Mitigation. Special features that may be used in underground storage
facilities to reduce airblast IBD include:

C5.2.3.3.1. Facility Layouts. A facility’s layout and its volume control the external
airblast effects.

C5.2.3.3.1.1. In a single-chamber facility with a straight access tunnel leading

from the chamber to the portal, which is commonly called a “shotgun” magazine, the blast and
debris are channeled to the external area as if fired from a long-barreled gun. In this type of
facility design, airblast mitigation, given a fixed NEWQD, can be provided by increased
chamber and tunnel dimensions.

C5.2.3.3.1.2. In more complex facility layouts, reflections of the explosive shock

against the various tunnel walls may reduce the exit pressures. The cumulative effects of these
reflections may reduce the overpressure at the shock front to that of the expanding gas pressure.
In addition, the detonation gas pressure decreases as the volume it occupies increases.
Therefore, larger, more complex facilities will produce greater reductions in the effective
overpressure at the opening, which will reduce the IBD.

C5.2.3.3.1.3. In a more complex facility with two or more openings, the IBD will
be reduced by about 10 percent.

C5.2.3.3.2. Expansion-Chambers. Expansion-chambers provide additional volume

for the expansion of the detonation gasses behind the shock front as it enters the chamber from a
connecting tunnel. Some additional reduction of the peak pressure at the shock front occurs as
the front expands into the expansion-chamber and reflects from the walls. Although expansion-

54 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

chambers may be used as loading areas or as turn-around areas for transport vehicles servicing
facilities through a single entry passage, they shall not be used for storage.

C5.2.3.3.3. Constrictions. Constrictions are short lengths of tunnel whose cross-

sectional areas are reduced to one-half or less of the normal tunnel cross-section. Constrictions
reduce the airblast effects passing through them. To be effective, constrictions should be placed
within five tunnel diameters of the tunnel exit or to the entrances of storage chambers. As an
added benefit, constrictions at chamber entrances also reduce the total loading on blast doors that
may be installed to protect a chamber’s contents.

...... C5.2.3.3.4. Portal Barricades. A barricade in front of the portal (entrance into tunnel)
will reflect that portion of the shock wave moving directly outward from the portal, thereby
reducing the pressures along the extended tunnel axis and increasing the pressures in the opposite
direction. The result is a more circular IBD area centered at the portal. A portal barricade
meeting the construction criteria of the CoE definitive drawing discussed in subparagraph
C5.2.3.1.2. will reduce the IBD along the extended tunnel axis by 50 percent. The total IBD area
is only slightly reduced, but will change to a circular area, half of which is behind the portal.

...... C5.2.3.3.5. High-Pressure Closures. High-Pressure Closures are large blocks

constructed of concrete or other materials that obstruct or greatly reduce the flow of blast effects
and debris from an explosion from or into a storage chamber.

C5.2.3.3.5.1. When used to reduce QD, by restricting the blast outflow from a
chamber, the block must be designed to be rapidly driven from an open to a closed position by
the detonation pressures in the chamber. While this type of block will provide some protection
of chamber contents from an explosion in another chamber, blast doors must also be used to
provide complete protection. Tests have shown that a closure block, with sufficient mass, can
obstruct the initial outflow of airblast from an explosion in a chamber to reduce pressures in the
connecting tunnels by a factor of two or more, even when the block is destroyed. Blocks with
sufficient strength to remain structurally intact can provide greater reductions. Because many
variables influence the performance of a closing device, their design details must be developed
on a site-specific basis.

C5.2.3.3.5.1.1. For loading densities (w) of 0.625 lb/ft3 [10 kg/m3] or higher,
a 50 percent reduction in IBD may be applied to the use of a high pressure closure block
provided it is designed to remain intact in the event of an explosion.

C5.2.3.3.5.1.2. For lower loading densities, use the following reductions:

C5.2.3.3.5.1.2.1. 0.0625 < w < 0.625 lb/ft3 [1.0 < w < 10 kg/m3],
reductions may be calculated by:
y(%) = 50log10(16.02w) [English EQN C5.2-1]
[y(%) = 50log10 (1.0w)] [Metric EQN C5.2-2]
where y is the percent reduction in IBD, and w is loading density in lb/ft3 [kg/m3]

C5.2.3.3.5.1.2.2. For w < 0.0625 lb/ft3 [w <1 kg/m3]:

55 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

y(%) = 0.

C5.2.3.3.6. When used to protect the contents of a chamber from an explosion in

another chamber, the block must be designed to move from a normally closed position to an
open position when entry is required. Blast doors are not required for this type of closure block.

C5.2.3.4. Chamber Separation Requirements. Minimum storage chamber separation

distances are required to prevent or control the communication of explosions or fires between
chambers. There are three modes by which an explosion or fire can be communicated: rock
spall, propagation through cracks or fissures, and airblast or thermal effects traveling through
connecting passages. Spalled rock of sufficient mass that is traveling at a sufficient velocity may
damage or sympathetically detonate impacted AE in the acceptor chambers.

C5.2.3.4.1. Prevention of Damage by Rock Spall (HD 1.1 and HD 1.3). The
chamber separation distance is the shortest distance (rock thickness) between two chambers.
When an explosion occurs in a donor chamber (a PES), a shock wave is transmitted through the
surrounding rock. The intensity of the shock decreases with distance. For small chamber
separation distances, the shock may be strong enough to produce spalling of the rock walls of
adjacent ES chambers. When no specific protective construction is used:

C5.2.3.4.1.1. For moderate to strong rock, with loading densities less than or
equal to 3.0 lb/ft3 [48.1 kg/m3], the minimum chamber separation distance (Dcd) required to
prevent hazardous spall effects is:
Dcd = 2.5W1/3 [English EQN C5.2-3]
[Dcd = .99Q1/3] [Metric EQN C5.2-4]
where Dcd is in ft and W is in lbs [Dcd is in m, and Q is in kg]. (NOTE: Dcd shall not be less than
15 ft [4.6 m].)

C5.2.3.4.1.1.1. For loading densities greater than 3.0 lbs/ft3 [48kg/m3], the
separation distance is:
Dcd = 5.0W1/3 [English EQN C5.2-5]
[Dcd = 1.98Q1/3] [Metric EQN C5.2-6]

C5.2.3.4.1.2. For weak rock, at all loading densities, the separation distance
is:
Dcd = 3.5W1/3 [English EQN C5.2-7]
[Dcd = 1.39Q1/3] [Metric EQN C5.2-8]

C5.2.3.4.1.3. The equations above are the basis for values of Dcd listed in Table
C5.T2.).

C5.2.3.5. Prevention of Propagation by Rock Spall (HD 1.1 and HD 1.3). Because rock
spall is considered an immediate mode of propagation, time separations between donor and
acceptor explosions may not be sufficient to prevent coalescence of blast waves. If damage to
AE stored in adjacent chambers is acceptable, chamber separation distances from those
determined to prevent damage (see subparagraph C5.2.3.2.1.) can be reduced to prevent

56 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

propagation by rock spall. To prevent propagation, the separation distances between donor and
acceptor chambers are calculated using the below equations. If the required separation distances
defined below cannot be met, explosives weights in all chambers must be added together to
determine W, unless analyses or experiments demonstrate otherwise.

C5.2.3.5.1. When no special protective construction is used, the separation distance

(Dcp) to prevent propagation by rock spall is:
Dcp = 1.5W1/3 [English EQN C5.2-9]
1/3
[Dcp = 0.59Q ] [Metric EQN C5.2-10]
where Dcp is in ft and W is in lbs. [Dcp is in m and Q is in kg]

C5.2.3.5.2. When the acceptor chamber has protective construction to prevent spall
and collapse, the Dcp to prevent propagation by impact of rock spall is:
Dcp = 0.75W1/3 [English EQN C5.2-11]
1/3
[Dcp = 0.30Q ] [Metric EQN C5.2-12]
where Dcp is in ft and W is in lbs. [Dcp is in m and Q in kg]

C5.2.3.5.3. Separation distances, Dcp and Dcd, are listed in Table C5.T2. These
distances are based on an explosive loading density of 17 lb/ft3 [272.3 kg/m3] and will likely be
safety conservative for lower loading densities.

C5.2.3.6. Prevention of Propagation Through Cracks and Fissures (HD 1.1 and HD 1.3).
Propagation between a donor and an acceptor chamber has been observed to occur when natural,
near-horizontal jointing planes, cracks, or fissures in the rock between the chambers are opened
by the lifting force of the detonation pressure. Prior to construction of a multi-chamber
magazine, a careful site investigation must be made to ensure that such joints or fissures do not
extend from one chamber location to an adjacent one. Should such defects be encountered
during facility excavation, a reevaluation of the intended siting is required.

C5.2.3.7. Prevention of Propagation through Passageways (HD 1.1 and HD 1.3). Flame
and hot gas may provide a delayed mode of propagation. Time separations between the events in
the donor chamber and the acceptor chamber by this mode will likely be sufficient to prevent
coalescence of blast waves. Consequently, siting is based on each chamber’s NEWQD. To
protect assets, blast and fire resistant doors may be installed within multi-chambered facilities.
Evaluations for required chamber separations due to this propagation mode should be made on a
site-specific basis using procedures outlined in CoE definitive drawing DEF 421-80-04. For HD
1.1 and HD 1.3 materials:

C5.2.3.7.1. Chamber entrances at the ground surface, or entrances to branch tunnels

off the same side of a main passageway, shall be separated by at least 15 ft [4.6 m].

C5.2.3.7.2. Entrances to branch tunnels off opposite sides of a main passageway shall
be separated by at least twice the width of the main passageway.

C5.2.3.8. Chamber Cover Thickness. The chamber cover thickness is the shortest
distance between the ground surface and the natural rock surface at the chamber’s ceiling or, in

57 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

some cases, a chamber’s wall. For all types of rock, the critical cover thickness required to
prevent breaching of the chamber cover by a detonation (Cc) is
Cc = 2.5W1/3 [English EQN C5.2-13]
1/3
[Cc = .99Q ] [Metric EQN C5.2-14]
where Cc is in ft and W is in lbs [Cc is in m and Q is in kg].

C5.2.4. HPM. HPM allow a reduction in encumbered land by limiting the MCE to a
quantity considerably less than that stored in the HPM. (NOTE: HPM are to be constructed per
NAVFAC guidance, as outlined in Table AP1-1. of Reference (j), and are to be sited at the IMD
provided by Table C9.T6.). HPM separation walls protect against fire propagation between
internal storage areas. Although IMD provides nearly complete asset protection between HPM
(MCE = 60,000 lbs [27,216 kg] maximum), AE damage may occur to about K9 [3.57] from a
donor NEW > 350,000 lbs [158,757 kg].

C5.2.5. AGM. There are no DDESB construction criteria for AGM. However, such
structures must meet the criteria of Chapters 6 and 7.

59 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.2.6. Special Structures. The DDESB has approved reduced QD for structures and
containers listed in Table AP1-4. of Reference (j).

C5.3. BARRICADES

C5.3.1. General

C5.3.1.1. Properly constructed and sited barricades and undisturbed natural earth have
explosives safety applications for both protecting against low-angle fragments and reducing
shock overpressure loads very near the barricade. Barricades provide no protection against high-
angle fragments or lobbed AE. If the barricade is destroyed in the process of providing
protection, then secondary fragments from the destroyed barricade must also be considered as
part of a hazards analysis.

C5.3.1.2. To reduce hazards from high-velocity, low-angle fragments, the barricade must
be placed between the PES and the ES so that the fragments of concern impact the barricade
before the ES. The barricade must both be thick enough so that it reduces fragment velocities to
acceptable levels and high enough so that it intercepts the ballistic trajectories of the fragments
of concern.

C5.3.1.3. A barricade placed between a PES and an ES interrupts the direct line-of-sight
motion of the shock wave. If the barricade has sufficient dimensions and is located close enough
to the ES, significant reductions in shock loading to selected areas of the ES may be realized.

C5.3.2. Barricade Designs

C5.3.2.1. Chapter 6 of Reference (j) lists DDESB-approved designs and construction

materials for barricades. Use of these barricades satisfies barricading criteria.

C5.3.2.2. Alternate barricade designs (e.g., earth-filled steel bin) may be approved by the
DDESB, provided that testing or analysis demonstrates their effectiveness in stopping high-
velocity, low-angle fragments.

C5.3.2.3. Barricade Size and Orientation for Protection Against High-Speed, Low-Angle
Fragments. The location, height, and length of a barricade shall be determined as follows:

C5.3.2.3.1. Location. The barricade may be placed anywhere between the PES and
the ES. The location shall determine the barricade’s required height and length.

C5.3.2.3.2. Height. To determine the required barricade height:

C5.3.2.3.2.1. Establish a reference point at the top of the far edge of one of the
two AE stacks between which the barricade is to be constructed. When both stacks are of equal
height, the reference point may be established on either stack. If the tops of the two stacks are
not of equal height (elevation), the reference point shall be on the top of the lower stack. To

60 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

preclude building excessively high barricades, the barricade should be located as close as
possible to the stack on which the reference point was established. (See Figure C5.F3.)

C5.3.2.3.2.2. Draw a line from the reference point to the highest point of the
other stack.

C5.3.2.3.2.3. Draw a second line from the reference point forming an angle of
two degrees above the line.

C5.3.2.3.3. Length. The barricade’s length shall be determined per Figure C5.F3.

C5.3.2.4. Barricade Size and Orientation for Protection Against Overpressure. General
procedures to predict pressure mitigation versus barricade design and location have not been
developed. However, based on direct-experimental work, the overpressure loading on a surface
area shielded by a barricade is reduced by approximately 50 percent when the following
conditions are met:

C5.3.2.4.1. Location. The barricade’s standoff is within two barricade heights of the
protected area.

C5.3.2.4.2. Height. The top of the barricade is at least as high as the top of the
protected area.

C5.3.2.4.3. Length. The length of the barricade is at least two times the length of the
protected area.

C5.3.3. Barricade Construction Materials

C5.3.3.1. Materials for earthen barricades shall be reasonably cohesive and free from
harmful (toxic) matter, trash, debris, and stones heavier than ten pounds [4.54 kg] or larger than
six inches [152 mm] in diameter. The larger of acceptable stones shall be limited to the lower
center of fills. Earthen material shall be compacted and prepared, as necessary, for structural
integrity and erosion control. Solid or wet clay or similar types of soil shall not be used in
barricades because they are too cohesive. If it is impossible to use a cohesive material (e.g., in
sandy soil) the barricade shall be finished with a suitable material (e.g., geotextiles, gunnite) that
shall not produce hazardous debris, but shall ensure structural integrity.

C5.3.3.2. The slope of an earthen barricade must be two horizontal to one vertical, unless
erosion controls are used. Earthen barricades with slopes no greater than one and one half
horizontal to one vertical that were approved prior to 1976 may continue to be used. However,
renovations to these facilities shall meet the above criteria, when feasible.

62 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.3.4. Portal Barricades for Underground Storage Facilities. Portal barricades allow
reduction in IBD for underground magazines. Criteria for the location and construction of portal
barricades are illustrated in Figure C5.F4. and include:

C5.3.4.1. Location. Portal (entry or exit) barricades shall be located immediately in front
of an outside entrance or exit to a tunnel leading to an explosives storage point. The portal
barricade should be centered on the extended axis of the tunnel that passes through the portal and
shall be located a distance of not less than one and not more than three tunnel widths from the
portal. The actual distance should be no greater than that required (based on the turning radius
and operating width) to allow passage of any vehicles or materials handling equipment that may
need to enter the tunnel.

C5.3.4.2. Height. The height of the barricade, along its entire width, shall be sufficient
to intercept an angle of 10 degrees above the extended height of the tunnel.

C5.3.4.3. Width and Length

C5.3.4.3.1. The width of the central face typically equals the width of the tunnel at
the portal.

C5.3.4.3.2. The front face (i.e., the face toward the entry or exit) shall be vertical and
concave in plan view, consisting of a central face oriented perpendicular to the tunnel axis, and
wing walls.

C5.3.4.3.3. The wing walls shall be of sufficient width so that the entire barricade
length intercepts an angle of 10 degrees (minimum) to the right and left of the extended tunnel
width.

C5.3.4.4. Construction. To withstand the impact of debris ejected from the tunnel, the
front face (including wing walls) shall be constructed of reinforced concrete, with a minimum
thickness equal to 10 percent of the barricade height, but in no case less than 12 inches [30.5
cm]. The concrete wall shall have a spread footing of sufficient width to prevent significant
settlement. In addition, the central wall, wing walls, and footing shall be structurally tied
together to provide stability. The backfill behind the concrete wall may be composed of any fill
material, to include rock rubble from the tunnel excavation, with a maximum particle size of 6
inches [15.2 cm] within the area extending out to 3 feet [0.9 m] from the rear face of the wall.

C5.3.5. Earth-Filled, Steel Bin-Type Barricades (ARMCO Revetments or Equivalent) for

Outside Storage

C5.3.5.1. These barricades, also known as ARMCO, Inc. revetments, are earth-filled
steel bins used to separate AE awaiting scheduled processing (e.g., AE on a flight line associated
with aircraft parking or loading operations; or the temporary positioning of AE awaiting transfer
to preferred, long-term storage). These barricades, which are also used to separate explosive-
loaded aircraft, are normally used to form a series of cells. They are designed to limit the MCE,
for QD siting purposes, of AE properly positioned in separate cells by preventing prompt
detonation transfer to adjacent cells.

64 CHAPTER 5
DoD 6055.09-STD, February 29, 2008

C5.3.5.2. ARMCO, Inc. Revetment Cells (see paragraph C6.2.3. of Reference (j)):

C5.3.5.2.1. ARMCO, Inc. revetments cells are approved for storage of any HD 1.1
and HD 1.2 AE assigned to SG 1 through 4, as discussed in paragraph C3.2.3. In addition,
storage of HD 1.3, HD 1.4, or HD 1.6 items is approved.

C5.3.5.2.2. When properly sited, these cells prevent prompt detonation transfer;
however, all assets in the series of cells are at risk of loss. Although a revetment is effective in
limiting the blast loading of an adjacent ES to that produced by the largest contents of a single
cell, there is a significant probability that the contents of many of the cells will be damaged or
destroyed by the initial and subsequent fire and explosion events. The extent of such losses
increases with the amount of explosives present.

C5.3.5.3. Types of ARMCO, Inc. Revetments

C5.3.5.3.1. Type A revetments, which must be a minimum of 7 feet [2.1 m]

thick, can be used to limit a MCE in a series of cells to the largest quantity in a single
cell, provided the quantity in the single cell does not exceed 30,000 pounds NEW [NEQ]
[13,608 kg].

C5.3.5.3.2. Type B revetments, which must be a minimum of 5.25 feet [1.6 m] thick,
can be similarly used to limit the MCE, provided no cell contains more than 5,000 pounds NEW
[2,268 kg NEQ].

C5.3.5.4. For ARMCO, Inc. revetments to be used effectively, the following conditions
must be met:

C5.3.5.4.1. The criteria shown in Figure C5.F3.

C5.3.5.4.2. AE shall be positioned no closer than 10 feet [3.1 m] from cell walls, no
closer than 3 feet [0.9 m] from the end of the wing walls, and no higher than 2 feet [0.6 m] below
the top of cell walls.

C5.3.5.4.3. AE shall be distributed over the available area within the cell, rather than
being concentrated in a small area.

C5.3.5.4.4. AE stored in a cell in quantities near the maximum NEW limit shall not
be configured into a single row of pallets, stacks, or trailers.

C5.3.5.4.5. The storage of AE in flammable outer-pack configurations shall be

minimized.

C5.4. SITE AND GENERAL CONSTRUCTION PLANS REVIEW

65 CHAPTER 5

stringent explosives safety criteria. (For example, an airfield restricted to DoD use only,
changed to joint DoD and non-DoD use.)

C5.4.2. Vulnerable facility construction. Although site plans for construction of vulnerable
facilities (e.g., schools, high-rise buildings, restaurants) located on a DoD installation that are
outside but near QD arcs are not required, it is recommended that they be submitted to the
DDESB for review and comment.

C5.4.3. Site and general construction plans need not be submitted to the DDESB for facility
modifications, change of mission, or change of operations that do not introduce additional
explosives hazards or do not increase NEW, chemical agent hazards, or personnel exposure.

DoD 6055.09-STD, February 29, 2008

C6. CHAPTER 6
ELECTRICAL STANDARDS

C6.1. GENERAL

This chapter establishes safety standards for the design and installation of electrical equipment
and wiring for explosives environments.

C6.1.1. For this purpose, the Department of Defense adopts Article 500 of the Code
“Hazardous (Classified) Locations” of the National Fire Protection Association (NFPA) 70
(Reference (l)) (a.k.a., National Electrical Code (NEC)). This Code establishes standards for the
design and installation of electrical equipment and wiring for atmospheres containing
combustible dusts, flammable vapors or gasses that are comparably hazardous.

C6.1.2. This chapter does not address extraordinarily hazardous situations (e.g.,
nitroglycerin manufacturing) that will require special consideration and design features. In these
situations, the DoD Components shall develop site-specific design criteria.

C6.2. HAZARDOUS LOCATIONS

NEC definitions of Class I, Division 1 and Class II, Division 1 hazardous locations are modified
as follows for DoD explosives applications:

C6.2.1. Areas containing explosives dusts or explosives that may through handling produce
dust capable of being dispersed in the atmosphere shall be regarded as Class II, Division 1.

C6.2.2. Areas in which explosives sublimation or condensation may occur shall be regarded
as both Class I, Division 1 and Class II, Division 1.

C6.3. SPECIAL OCCUPANCIES

To ensure assignment to the proper hazardous location, class, and group, it is necessary to have
knowledge of the properties of explosives involved. Minimum requirements include sensitivity
to heat and spark and thermal stability.

C6.3.1. If the properties of an explosive are such that Class I or Class II, or both, provide
inadequate protection under prevailing conditions, use of any of the following approaches is
acceptable:

C6.3.1.1. Intrinsically safe equipment.

C6.3.1.2. Purged or pressurized and suitably temperature-limited equipment.

70 CHAPTER 6
DoD 6055.09-STD, February 29, 2008

C6.3.1.3. Exclusion of electrical equipment from the hazardous atmosphere.

C6.3.1.4. Isolation of equipment from the hazardous atmosphere by means of dust, vapor,
or gas-free enclosures with surface temperatures positively maintained at safe levels.

C6.3.2. Underground Storage Facilities. All wiring and electrical equipment in underground
storage facilities shall, in addition to any other requirements of this chapter, be of moisture and
corrosion-resistant materials and construction unless a site-specific analysis indicates that such
construction is not necessary. Underground facilities shall have emergency lighting systems to
provide minimum illumination in the event of a power failure.

C6.4. STATIC ELECTRICITY

Personnel and equipment in hazardous locations (section C6.2.) and locations where static
sensitive Electro-Explosive Device (EED) are exposed shall be grounded in a manner that
effectively discharges static electricity and prevents static electricity accumulations that may be
capable of initiating dusts, gases, vapors, or exposed EED. Permanent equipment in contact with
conductive floors and tabletops shall not be considered grounded. Static grounds shall be
bonded to the facility’s grounding system. (See Chapter 7.)

C6.5. ELECTRIC SUPPLY SYSTEMS

There may be mutual hazards when PES are located near electric supply lines. To protect
against these hazards, the following separation requirements apply to all new construction
(PTRD and IBD specified in paragraphs C6.5.3. and C6.5.4. are based on airblast overpressure
only; fragment distances do not apply):

C6.5.1. Electric lines serving explosives operating facilities shall be installed underground
from a point not less than 50 ft [15.3 m] away from such facilities.

C6.5.2. Overhead electric service lines shall be no closer to combustible PES or to an open
PES than the length of the electric lines between the nearest service poles and the length of the
nearest service pole. An exception is when an effective means (e.g., line spacers, weights) is
provided to ensure that energized lines on breaking cannot come into contact with the facility or
its appurtenances.

C6.5.3. Electric distribution lines carrying less than 69 kilovolt (kV), the tower or poles
supporting those lines, and unmanned electrical substations shall be no closer to PES than PTRD.
(Lesser distance permitted by section C9.4. for the placement of electrical substations and
transformers that support explosives areas.)

C6.5.4. Electric transmission lines carrying 69 kV or more and the tower or poles supporting
them shall be located no closer to the PES than:

71 CHAPTER 6
DoD 6055.09-STD, February 29, 2008

C6.5.4.1. IBD, if the line in question is part of a grid system serving a large off-base
area.

C6.5.4.2. PTRD, if loss of the line does not create serious social or economic hardships.

C6.5.5. Electric transmission lines that can be interrupted without loss of power (i.e., power
is rerouted through existing lines or networks) shall be separated from explosives sites in
accordance with paragraph C6.5.2.

C6.6. HAZARDS OF ELECTROMAGNETIC RADIATION TO ORDNANCE (HERO)

Military Munitions (at times also referred to as ordnance or AE) containing Electrically Initiated
Devices (EID) shall be designed or protected such that Electromagnetic Radiation (EMR) does
not cause their inadvertent initiation, degradation, or disablement. Both direct Radio Frequency-
(RF) induced actuation of the EID or electrical coupling to and triggering of the associated firing
circuits can occur, especially in a tactical radiated Electromagnetic Environment (EME).
Examples of EID include the following: exploding foil initiators, laser initiators, burn wires,
fusible links, and EED, such as hot bridge wires, carbon bridges, and conductive compositions.

C6.6.1. During acquisition, HERO testing and certification shall be accomplished, both for
routine employment mission profiles, and for any anticipated joint- or combined-operational
employment to include transshipment exposures through EME differing from the employment
environment.

C6.6.2. During subsequent phases of life cycle munitions management, additional HERO
testing and certification shall be accomplished when legacy munitions are redesigned or before
any employment through EME for which they where not previously HERO certified.

C6.6.3. Minimally, HERO certification shall involve exposure without adverse effects of the
munitions to the EME relevant to all life cycle configurations, including packaging, handling,
storage, transportation, checkout, loading and unloading, and launch.

C6.6.4. All HERO test and certification data shall be compiled in a centralized data
repository to support the Joint Spectrum Center Ordnance Electromagnetic Environmental
Effects (E3) Risk Assessment Database (JOERAD), for subsequent use in information
applications supporting Combatant Commands and the DoD Components.

C6.6.5. The DoD Components shall take measures (e.g., identifying susceptibilities,
quantifying electromagnetic environments, evaluating risks associated with operating
procedures, and establishing tailored Emission Control (EMCON) instructions) to ensure that
HERO effects on munitions are resolved during the planning of joint or combined operations or
training exercises.

C7. CHAPTER 7
LIGHTNING PROTECTION

C7.1. POLICY

This chapter defines minimum explosives safety criteria for the design, maintenance, testing, and
inspection of Lightning Protection Systems (LPS). Properly maintained LPS are required (with
exceptions) for AE facilities. If other LPS for these facilities are used, they shall offer equivalent
protection to the types prescribed herein.

C7.2. LPS DESIGN

C7.2.1. Design and installation of an LPS used to protect DoD AE must meet, at a minimum,
the requirements of NFPA 780 Lightning Protection Code (Reference (m)). LPS must feature air
terminals, low impedance paths to ground, sideflash protection, surge suppression or grounding
of all conductive penetrations into the protected area, and earth electrode systems. Structural
elements of the building may serve as air terminals, down conductors, or the earth electrode.
LPS used to protect DoD AE must be designed to intercept lightning at a 100 ft [30.5 m] or less
striking distance arc in accordance with Reference (m).

C7.2.1.1. Air Terminals. An air terminal is a component of an LPS that is able to safely
intercept lightning strikes. Air terminals may include overhead wires or grids, vertical spikes, or
a building’s grounded structural elements. Air terminals must be capable of safely conducting a
lighting strike.

C7.2.1.2. Down Conductors. Down conductors (flat or round) provide low impedance
paths from the air terminals to the earth electrode (ground) system. Structural elements having a
high-current capacity and a low impedance to ground need not be augmented with wires. Where
wires are used as down conductors, these shall meet the requirements of Reference (m).

C7.2.1.3. Sideflash Protection. Protection from sideflash caused by lightning shall be

obtained by either separation distance or bonding in accordance with Reference (m), except as
modified herein.

C7.2.1.3.1. Fences and railroad tracks located within six feet of a structure’s LPS
shall be bonded to the structure’s LPS.

C7.2.1.3.2. The reinforcing bars in adjacent structural elements must be joined in a

manner to provide electrical bonding between the elements. This is an absolute requirement for
facilities that are used to store AE. Techniques commonly used and approved in the construction
industry to join reinforcing steel are acceptable for this purpose. The steel arch of an ECM must
be similarly joined to the rebar in the floor.

73 CHAPTER 7
DoD 6055.09-STD, February 29, 2008

C7.2.1.4. Surge Protection for Incoming Conductors. An LPS shall include surge
protection for all incoming conductors. The surge protection must include suppression at the
entrance to the building from each wire to ground. Shielded cabling, power cabling,
communication lines, and electrical conduit shall be buried underground in conduit for a
minimum of 50 feet [15.3 m] before entering the structure. All other metallic utility lines and
pipes must be electrically connected to the LPS or the structural steel of the building just before
they enter the building.

C7.2.1.5. Earth Electrode System. Earth electrode systems dissipate the current from a
lightning strike to ground. Earth electrode systems may be Ufer grounds, ground loop
conductors, radials, grounding rods, ground plates, a cable immersed in nearby salt water,
chemical grounds that are installed for the purpose of providing electrical contact with the earth,
or combinations of these.

C7.2.2. Underground Storage Facility.

An underground storage site normally requires designed protection against lightning only for
exposed or partially exposed parts. Metal and structural parts of the site that have less than 2 feet
[60 cm] of earth cover shall be protected as for an aboveground site. Lightning protection
requirements shall be considered on a site-specific basis.

C7.3. INSPECTION, TESTING, AND TRAINING

C7.3.1. Visual inspection. LPS shall be periodically inspected at a frequency determined by

each DoD Component. Visual inspections shall be conducted at least yearly.

C7.3.2. Electrical tests. LPS shall be periodically tested electrically as specified in

subparagraphs C7.3.2.1. and C7.3.2.2. Electrical testing shall be accomplished at least every 2
years.

C7.3.2.1. Bonding (Resistance) Tests. Bonding (resistance) tests shall be conducted

periodically (or after facility modification that may affect bonding). A maximum resistance
value of one ohm is permitted across all bonds.

C7.3.2.2. Resistance to Earth Tests. Resistance to earth tests of LPS shall be conducted
periodically during the same season of the year (or after facility modification that may have
affected the system).

C7.3.3. Records. Records of resistance to earth tests shall be kept on file for the last six
inspection cycles. These records shall be reviewed for trend analysis.

C7.3.4. Training. Personnel responsible for maintenance, inspection, and testing must be
familiar with the fundamentals described in Reference (m) and herein as they relate to AE
facilities to ensure requirements of paragraphs C7.3.1. and C7.3.2. are met.

74 CHAPTER 7
DoD 6055.09-STD, February 29, 2008

C7.4. LIGHTNING PROTECTION EXCEPTIONS

Properly maintained LPS are required for AE facilities, with the follow exceptions:

C7.4.1. Explosives operations served by a local lightning warning system that permit
operations to be terminated before the incidence of an electrical storm, if all personnel are
provided with protection equivalent to PTRD, and the damage from a lighting strike is
acceptable to the DoD Component.

C7.4.2. Facilities containing only AE that cannot be initiated by lightning, as determined by

the DoD Component concerned and approved by DDESB, and where no fire hazard exists.

C7.4.3. Facilities where personnel are not expected to sustain injury and at the same time,
the resulting economic loss of the structure, its contents, and/or surrounding facilities is minimal.

75 CHAPTER 7
DoD 6055.09-STD, February 29, 2008

C8. CHAPTER 8
HAZARD IDENTIFICATION FOR FIREFIGHTING
AND EMERGENCY PLANNING

C8.1. SCOPE AND APPLICABILITY

C8.1.1. This chapter establishes standard firefighting hazard identification measures to

ensure a minimum practicable risk in fighting fires involving AE. These identification measures
are based on the classification of AE fires into four fire divisions according to their predominant
hazard. Guidelines are provided to DoD Components for the development of emergency plans,
which include safety, security, and environmental protection. These plans shall be coordinated
with local authorities.

C8.1.2. The following are outside the scope of this chapter and are the responsibility of the
DoD Component:

C8.1.2.1. Firefighting procedures.

C8.1.2.2. Training of firefighting personnel.

C8.1.2.3. Use and maintenance of firefighting equipment and vehicles.

C8.1.2.4. Provision of water supply and alarm systems.

C8.1.2.5. First aid measures.

C8.1.2.6. Other measures required in firefighting.

C8.1.3. AE hazard symbols and supplemental symbols including chemical agent symbols
(see section C8.4.) are for firefighting situations.

C8.2. FIRE DIVISIONS

There are four fire divisions. Fire division 1 indicates the greatest hazard. The hazard decreases
with ascending fire division numbers from 1 to 4 and is related to HD as shown in Table C8.T1.

Table C8.T1. Fire Divisions

Fire Division Predominant Hazard HD

1 Mass explosion 1.1 and 1.5
2 Non-mass explosion, fragment producing 1.2 and 1.6
3 Mass fire, minor blast or fragment 1.3
4 Moderate fire, no blast or fragment 1.4

77 CHAPTER 8
DoD 6055.09-STD, February 29, 2008

C8.3. FIRE DIVISION SYMBOLS

C8.3.1. The four fire divisions are represented by four distinctive symbols so that
firefighting personnel can recognize the hazards. A fire division number is shown on each
symbol. For the purpose of identifying these symbols from long range, the symbols differ in
shape as shown in Table C8.T2.

Table C8.T2. Fire Division Symbols

Shape Fire Division Symbol

Octagon 1
Cross 2
Inverted triangle 3
Diamond 4

C8.3.2. The shape and dimensions of the symbols are shown in Figure C8.F1. This shape
and color scheme is consistent with UN, North Atlantic Treaty Organization (NATO), and
International Maritime Organization (IMO) requirements. For application on doors or lockers
inside buildings, half-sized symbols may be used.

C8.3.3. At the discretion of the DoD Components, circumstances (e.g., security) may make
it undesirable to post fire symbols at an AE storage site.

C8.4. CHEMICAL AGENT AND CHEMICAL MUNITION HAZARD SYMBOLS

C8.4.1. The storage of chemical agents and chemical munitions requires the use of chemical
hazard symbols. These symbols (see Figures C8.F2. and C8.F3.) shall be used in conjunction
with fire symbols, where appropriate. Some of the common chemical agents used in AE, the CG
of that AE, and the chemical hazard symbols required in storage are specified in Table C8.T3.

C8.4.2. The following sections describe these symbols, the hazards indicated by the
symbols, and the recommended protective clothing and equipment to be used for fighting fires
involving these chemical agents and chemical munitions. The DoD Components shall determine
protective clothing requirements for other than firefighting situations.

bunker suit) and gas mask or SCBA do not require the set 3 protective clothing.

C8.4.2.4. Chemical hazard symbol 2 requires the wearing of breathing apparatus (see
Figure C8.F2. and Table C8.T3.) and indicates the presence of incendiary or readily flammable
chemical agents that present an intense radiant heat hazard. Protective masks shall be used to
prevent inhalation of smoke from burning incendiary mixtures.

C8.4.2.5. Chemical hazard symbol 3 warns against applying water (see Figure C8.F2.
and Table C8.T3.) and indicates a dangerous reaction will occur if water is used in an attempt to
extinguish fire.

C8.5. FIREFIGHTING MEASURES

C8.5.1. Firefighters should have a thorough knowledge of the hazards associated with AE
fires and expected AE reactions. The DoD Component shall brief the firefighting forces and
other essential personnel before approaching the scene of the fire. They shall be informed of the
known hazards and conditions existing at the fire scene prior to proceeding to the fire location.

C8.5.2. Fires involving AE will be fought according to the HD, fire division, the progression
of the fire, and the procedures specified by the DoD Component. Special firefighting

83 CHAPTER 8
DoD 6055.09-STD, February 29, 2008

instructions addressing AE hazards will be developed according to the needs of the DoD
Component.

C8.5.3. All fires in the vicinity of AE shall be immediately reported and:

C8.5.3.1. Shall be fought if not involving AE.

C8.5.3.2. Shall not be fought if the fire involves AE, or is supplying heat to the AE, or is
so large that it cannot be extinguished with the equipment at hand. Personnel shall be evacuated
per paragraph C8.5.4.

C8.5.4. Emergency Withdrawal Distances. Commanders are responsible for developing

evacuation plans that include the applicable withdrawal distances as part of the installation’s
emergency planning (see section C8.6.).

C8.5.4.1. Nonessential Personnel. These emergency withdrawal distances are intended

for application in emergency situations only and are not used for facility siting.

C8.5.4.1.1. The initial withdrawal distance for nonessential personnel shall be at least
IBD for the PES involved. If the fire involves AE, AE involvement is imminent, or the fire is or
may become uncontrollable, then use the emergency withdrawal distances listed in Table C8.T4.
The emergency withdrawal distances depend on fire involvement and on whether or not the HD,
fire division and quantity of explosives are known. If fire is not affecting AE or involvement is
not imminent, then emergency authorities shall determine the withdrawal distance based on the
situation at hand.

C8.5.4.1.2. Structures or protected locations offering equivalent protection for the

distances in Table C8.T4. may be used in lieu of relocating personnel from the structure or
location to the specified emergency withdrawal distance.

C8.5.4.2. Essential Personnel. Emergency authorities on site shall determine the

withdrawal distance for essential personnel at accidents. Emergency authorities shall determine
the essential personnel.

C8.5.5. AE containing both explosives and chemical agents (see Table C8.T3.) requires
special attention and precautions in firefighting. Fires involving such AE shall be fought in
accordance with their fire division characteristics. Responding personnel must consider the
additional hazards and precautions discussed in Chapter 11 for the chemical agents involved.

C8.5.6. Entry to underground storage facilities following a fire or explosion requires special
precautions. Emergency personnel shall monitor for the presence of toxic fumes or oxygen-
depleted atmospheres and evaluate structural damage during initial entry following an accident.
Commanders shall develop written procedures that define actions to be taken in such emergency
situations.

84 CHAPTER 8
DoD 6055.09-STD, February 29, 2008

C8.6. EMERGENCY PLANNING

C8.6.1. Installations or responsible activities shall develop Standard Operating Procedures

(SOP) or plans designed to provide safety, security, and environmental protection for accidents
involving AE. Plans shall be coordinated with the applicable Federal, State, and local
emergency response authorities (e.g., law enforcement, fire departments, and hospitals) and any
established Local Emergency Planning Committees (LEPC). The SOP or plans shall include the
following:

C8.6.1.1. Specific sections and guidance that address emergency preparedness,

contingency planning, and security. (For security, the SOP or plans shall limit access to accident
sites to trained and authorized personnel.)

C8.6.1.2. Procedures that minimize the possibility of an unpermitted or uncontrolled

detonation, release, discharge, or migration of AE out of any storage unit when such release,
discharge, or migration may endanger human health or the environment.

DoD 6055.09-STD, February 29, 2008

C9. CHAPTER 9
QUANTITY-DISTANCE AND SITING

C9.1. GENERAL

The damage or injury potential of explosions is normally determined by the separation distance
between PES and ES; the ability of the PES to suppress blast overpressure, primary and
secondary fragments; and the ability of the ES to resist explosion effects. This chapter:

C9.1.1. Defines permissible exposures for both accidental and intentional detonations.

C9.1.2. Sets minimum standards for separation distances between PES and ES by taking into
account anticipated explosion effects, suppression, and resistance.

C9.1.3. Establishes explosives safety siting criteria (QD relationships) for PES and ES,
based on blast, fragment, firebrand, thermal, and groundshock effects. QD is determined by the
effect requiring the greatest distance.

C9.2. DETERMINING THE QUANTITY OF EXPLOSIVES

C9.2.1. General. The NEWQD in an AE facility is calculated as shown below. If DDESB-

approved buffer configurations are provided, the NEWQD is the explosives weight of the largest
stack plus the explosives weight of the buffer material, excluding the NEW of HD 1.4. Where
the DDESB has approved an HE equivalence for a propellant or pyrotechnic, then this HE
equivalence may be used in determining NEWQD. (The JHCS provides explosives weights for
all DoD Hazard Classified AE.)

C9.2.1.1. Mass-explosion (HD 1.1). The NEWQD is the total High Explosive Weight
(HEW) and the total Net Propellant Weight (NPW). For HD 1.1, NEWQD equals the NEW.

C9.2.1.2. Non-mass Explosion, Fragment Producing (HD 1.2).

C9.2.1.2.1. HD 1.2.1. The NEWQD is the HEW plus the NPW in all HD 1.2.1
items. In certain situations, the MCE, as outlined in subparagraph C9.4.2.5., shall be used as the
basis for determining applicable QD.

C9.2.1.2.2. HD 1.2.2. The NEWQD is the HEW plus the NPW in all HD 1.2.2
items.

C9.2.1.2.3. HD 1.2.3. The NEWQD is the HEW plus the NPW in all HD 1.2.3
items. This material is treated as HD 1.3, however, a minimum IBD shall apply, as outlined in
subparagraph C9.4.2.12.

88 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.2.1.3. Mass Fire, Minor Blast, or Fragment (HD 1.3). The NEWQD is the HEW plus
the NPW plus the total weight of pyrotechnics in all HD 1.3 items.

C9.2.1.4. Moderate Fire, No Blast, or Fragment (HD 1.4). The NEWQD is the HEW
plus the NPW plus the total weight of pyrotechnics in all HD 1.4 items.

C9.2.1.5. Explosive Substance, Very Insensitive (With Mass Explosion Hazard) (HD
1.5). The NEWQD is the HEW plus the NPW in all HD 1.5 items. For HD 1.5, NEWQD equals
the NEW.

C9.2.1.6. Explosive Article, Extremely Insensitive (HD 1.6). The NEWQD is the total
weight of EIDS in all HD 1.6 items. However, the weight of EIDS in a single HD 1.6 item shall
also be considered, as specified in Table C9.T15., for determining QD.

C9.2.1.7. Exclusions. Munitions’ fillers that do not contribute to explosive effects (e.g.
colored and HC smoke, dyes, irritants, WP, PWP, and TPA) are excluded when determining
NEWQD.

C9.2.2. Determining the NEWQD for Mixed HD

C9.2.2.1. General

C9.2.2.1.1. The presence of HD 1.4 does not affect the NEWQD of mixed HD.
However, for QD determinations, HD 1.4 criteria shall be considered.

C9.2.2.1.2. When HD 1.1 is mixed with any other HD, treat the mixture as HD 1.1
except as noted in subparagraph C9.2.2.2.

C9.2.2.1.3. HD 1.5 is always treated as HD 1.1.

C9.2.2.1.4. When dissimilar HD 1.6 are mixed and have not been tested to ensure
non-propagation, the mixed HD 1.6 AE shall be individually considered to be HD 1.2.1 or HD
1.2.2, based on their individual NEWQD or over-riding fragmentation characteristics.

C9.2.2.2. HD 1.1 with HD 1.2 (HD 1.2.1, HD 1.2.2, and HD 1.2.3). Use whichever of
the following generates the largest QD:

C9.2.2.2.1. Sum the NEWQD for HD 1.1 and NEWQD for HD 1.2 and treat the
mixture as HD 1.1.

C9.2.2.2.2. The NEWQD of the mixture is the NEWQD of the HD 1.2 subdivision
requiring the largest QD.

C9.2.2.3. HD 1.1 with HD 1.3. Sum the NEWQD for HD 1.1 and the NEWQD for HD
1.3 and treat the mixture as HD 1.1.

89 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.2.2.4. HD 1.1 with HD 1.6. Sum the NEWQD for HD 1.1 and the NEWQD for HD
1.6 and treat the mixture as HD 1.1.

C9.2.2.5. HD 1.2.1 with HD 1.2.2. The NEWQD for the mixture is the NEWQD of the
subdivision requiring the largest QD.

C9.2.2.6. HD 1.2.1 with HD 1.2.3. The NEWQD for the mixture is the NEWQD of the
subdivision requiring the largest QD.

C9.2.2.7. HD 1.2.2 with HD 1.2.3. The NEWQD for the mixture is the NEWQD of the
subdivision requiring the largest QD.

C9.2.2.8. HD 1.2.1 with HD 1.2.2 with HD 1.2.3. The NEWQD for the mixture is the
NEWQD of the subdivision requiring the largest QD.

C9.2.2.9. HD 1.2 (HD 1.2.1, HD 1.2.2, and HD 1.2.3) with HD 1.3. The NEWQD for
the mixture is the NEWQD of the HD requiring the largest QD.

C9.2.2.10. HD 1.2 (HD 1.2.1, HD 1.2.2, and HD 1.2.3) with HD 1.6. Treat the HD 1.6
as HD 1.2.3 and determine NEWQD in accordance with (IAW) subparagraphs C9.2.2.6. through
C9.2.2.8., as applicable.

C9.2.2.11. HD 1.3 with HD 1.6. Sum the NEWQD for the HD 1.6 and the NEWQD for
the HD 1.3 and treat the mixture as HD 1.3.

C9.3. QD PRINCIPLES

C9.3.1. General

C9.3.1.1. The bases for determining required separation distances (i.e.,QD) are:

C9.3.1.1.1 The HD types and NEWQD of AE present in an AE facility.

C9.3.1.1.2. The NEWQD of the HD requiring the greatest separation establishes the
QD for the facility when it is used for multiple operations.

C9.3.1.1.3. The NEWQD for the HPM is based on its MCE (i.e., the sum of the
contents of an individual open cell and the loading dock, rather than the aggregate NEWQD for
the entire magazine). (The MCE for the HPM shall not exceed 60,000 lbs [27,215 kg].)

C9.3.1.2. The bases for subdividing a quantity of AE into smaller units for the purpose of
QD reduction are provided below.

C9.3.1.2.1. Separation By Time. When two or more stacks of equal NEWQD

detonate within short time intervals, the blast waves will coalesce. A short time interval is

90 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

defined as a time in milliseconds that is less than 4.0W1/3 [5.21Q1/3] of any one stack in lbs [kg]
for lateral (side-to-side) target positions and less than 5.6W1/3 [7.29Q1/3] of any one stack in lbs
[kg] for axial target positions. (In the preceding formulas, the unit for the constant is
milliseconds/lbs1/3 [milliseconds/kg1/3].) The combined shock wave, after coalescence, will be
that of a single detonation of a charge equal to the summation of the several stacks. When
coalescence does not occur, the MCE for the stacks is equal to the NEWQD for one stack.

C9.3.1.2.2. Separation By Barriers. Barriers designed per the principles of Reference

(j) shall ensure no propagation between AE stacks. When barriers are constructed per this
guidance or when supported by test data, the MCE is equal to the NEWQD of the AE stack with
the largest QD requirement. Otherwise, QD computations must be based upon the summation of
NEWQD for all of the AE stacks. (Barrier design shall include adequate standoff distances and
take into account acceptor AE sensitivity.)

C9.3.1.3. The QD criteria for a PES-ES pair, when both contain AE, are determined by
considering each location, in turn, as a PES and an ES. The quantity of AE to be permitted in
each PES shall be the amount permitted by the distance specified in the appropriate QD tables.
The separation distance required for the pair is the greater of the two separation distances. An
exception is permitted for service magazines supporting an AE operation.

C9.3.1.4. Flight ranges for units (e.g., rockets, missile motors, and Cartridge or
Propellant Actuated Devices (CAD/PAD)) in a propulsive state shall be disregarded because it is
impractical to specify QD separations that allow for their designed flight range.

C9.3.1.5. Separation distances are measured along straight lines. For large intervening
topographical features such as hills, measure over or around the feature, whichever is shorter.
For golf courses, measure to the nearest edge of the tee or green or to the centerline of fairways.

C9.3.1.6. Measurements of distance for determining the maximum allowable quantity of

AE shall be made to the nearest part of an ES from:

C9.3.1.6.1. The nearest wall of the PES.

C9.3.1.6.2. The exterior of the nearest intervening wall to the controlling AE stack,
when the PES is subdivided.

C9.3.1.7. When an AE conveyance (e.g., railroad car or motor vehicle) containing AE is

not separated from a PES in such a manner as to prevent mass detonation, then the conveyance
and PES shall be considered as a unit and their NEWQD shall be summed. The separation
distance shall be measured from the nearest outside wall of the PES or conveyance, as
appropriate, to an ES. If the AE are separated so that mass detonation will not occur, the
separation distance shall be measured from the nearest controlling PES or conveyance to an ES.

C9.4. QD CRITERIA FOR ACCIDENTAL DETONATIONS

C9.4.1.1.1.2.1. Unmanned auxiliary utility facilities (e.g., transformer

stations, water treatment and pollution abatement facilities) that serve, but are not an integral
function in the PES, and that would not create an immediate secondary hazard if lost. Such
unmanned facilities need not be barricaded. See subparagraph C9.8.1.2. for situations where
auxiliary facilities serving only one PES or AE operation are permitted to be separated from the
facility or operation they support based on fire separation distance only.

C9.4.1.1.1.2.2. Unmanned auxiliary power generation or conversion facilities

C9.4.1.1.2.1.2. Buildings, excluding magazine-area loading docks, for

comfort, safety, or convenience (e.g., lunchrooms, motor pools, area offices, auxiliary fire
stations, transportation dispatch points, and shipping and receiving buildings) that are used
exclusively in support of the PES.

C9.4.1.1.2.1.3. Parallel operating lines, whether or not barricaded, provided

the AE involved in each operating line present similar hazards. (The criticality or survivability
of one or more of the operating lines may require that each line be given IBD-level protection.)

C9.4.1.1.2.1.4. Operational support buildings (e.g., day rooms, operation

offices, and similar functions) that only personnel from the activity operating the PES use or
attend.

C9.4.1.1.2.1.5. Training functions (e.g., classroom and field training of

personnel who may be required to engage in AE work) that only personnel from the activity
operating the PES use or attend. (Maneuver areas, proving ground tracks, and similar facilities
for armored vehicles also may be exposed to 3.5 psi [24 kPa] because the vehicles provide
adequate protection to the operators from fragments and debris.)

C9.4.1.1.2.1.6. Maintenance of military vehicles or equipment that are

located outside the United States (U.S.), when the PES is a basic load or a ready storage area. In
such cases:

C9.4.1.1.2.1.6.1. The NEWQD at each PES is limited to 8,818 lbs [4,000

kg] or less.

complex, or when loss of the facility shall cause an immediate loss of vital function, the
minimum exposure level shall be IBD (40-50W1/3 [15.87-19.84Q1/3]).

93 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.1.2.1.7.2. Naval station “cold-iron” ship support facilities (e.g.,

supply and mechanical support) are excluded from QD criteria when they are not continuously
manned; when they are serving only the waterfront area; and when the PES is a ship or AE
handling location on the waterfront.

C9.4.1.1.2.1.8. Minimum distance between separate groups of AE-loaded,

combat-configured aircraft or between aircraft and a pre-load or “quick-turn” site that serves to
arm an aircraft. The use of intervening barricades is required to eliminate propagation by
primary fragment impact; thereby eliminating the need to total NEWQD. (Loading AE aboard
aircraft can be accomplished with each group of aircraft without additional protection.)

C9.4.1.1.2.1.9. Unbarricaded service magazine separation distances shall be

based on the NEWQD and the HD of the AE in the magazine and not that in other parts of the
operating line.

C9.4.1.1.2.1.10. Container stuffing and unstuffing operations that provide

routine support to a PES and apply only to main support functions that are set aside for support
of ship-loading, depot, or manufacturing operations. When in connection with ship-loading and
unloading and the ES is an AE ship, the quantity at the container site governs. (NOTE:
Container stuffing and unstuffing in a magazine area are permitted at IMD IAW Table C9.T6.)
Criteria applicable to the loading and unloading of a conveyance at a magazine are addressed in
paragraph C9.8.20.

C9.4.1.1.2.1.11. Combat Aircraft Support Facilities

C9.4.1.1.2.1.11.1. Between AE-loaded combat aircraft and those non-AE

facilities that directly support the servicing and launching of a unit’s armed aircraft. Such
facilities include operating facilities that handle AE on the flightline, prepare and service armed
aircraft, and those that house personnel who fly combat aircraft.

C9.4.1.1.2.1.11.2. Direct flightline combat aircraft associated facilities,

which may contain field offices, break rooms, unit training rooms, and equipment and supply
rooms, as well as Petroleum, Oils, Lubricants (POL) hydrant facilities and civil engineer fire
protection stations. (Morale, Welfare, and Recreation (MWR) facilities; base civil engineering
headquarters; and industrial facilities, including central base supply, are required to be at IBD.)

C9.4.1.1.2.1.12. Parking lots for Privately Owned Vehicles (POV) belonging

to personnel employed at or stationed at multiple PES. When a POV parking lot supports a
single PES, it may be separated at less than ILD only from its associated facility; however, a
minimum distance of 100 ft [30.5 m] is required to the PES it supports, to protect the PES from
vehicle fires. Access for emergency vehicles must be provided.

C9.4.1.1.2.2. Exposures indicated in this section that are provided blast

suppression and structure hardening so that comparable protection levels for personnel and
equipment as provided by 18W1/3 [7.14Q1/3] may be sited at 9W1/3 [3.57Q1/3].

94 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.1.3. 2.3 psi [15.8 kPa] at 24W1/3 [9.52Q1/3]. Personnel exposed to remotely
controlled operations.

C9.4.1.1.4. 2.3-1.7 psi [15.8-11.7 kPa] at 24-30W1/3 [9.52-11.9Q1/3].

C9.4.1.1.4.1. PTRD with medium and low traffic densities as described in

subparagraph C9.4.1.2.1.1.5.

C9.4.1.1.4.2. On-base roads. The DoD Components may provide protection less
than 60 percent of IBD to installation-related personnel transiting QD arcs, when the risks are
evaluated, are documented, and are IAW DoD Component-established procedures. (Effective
October 1, 2000, all new construction of AE storage and operating facilities, and any change in
operations within existing facilities that increases the explosive safety risk should provide both
the general public and installation-related personnel who are not involved in munitions-related
operations protection that provides a minimum of 60 percent of IBD.) When a DoD Component
determines exposures at less than 60 percent of IBD to be necessary, the DoD Component should
consider use of methods to inform transients of potential risks (e.g., written acknowledgement of
the risk by vendors or others with a recurring need to transit the ESQD area, warning signs,
flashing lights, physical barriers). The DoD Component’s decision to provide transients’
protection at less than 60 percent of IBD shall be:

C9.4.1.1.4.2.1. Supported by a qualitative risk assessment considering factors

such as:

C9.4.1.1.4.2.1.1. Operational necessity.

C9.4.1.1.4.2.1.2. The operation being performed (e.g., static storage,

maintenance, and production).

C9.4.1.1.4.2.1.3. Operational activity cycles.

C9.4.1.1.4.2.1.4. Alternate routes.

C9.4.1.1.4.2.1.5. Traffic density.

C9.4.1.1.4.2.1.6. Accident records.

C9.4.1.1.4.2.1.7. Time interval of exposure.

C9.4.1.1.4.2.1.8. Type and quantity of AE in proximity to the area

transited.

C9.4.1.1.4.2.1.9. The closest distance from the area transited to the PES.

95 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.1.4.2.1.10. The need for installation-related personnel to transit the

ESQD arc.

C9.4.1.1.4.2.2. Reviewed as changes occur to either operations, which would

increase the explosive safety risk, or the number of exposed, and upon change of the approving
authority.

C9.4.1.1.4.3. Open-air recreation facilities (e.g., ball diamonds, golf courses, and
volleyball courts), which do not contain structures, used for MWR and community relations’
purposes at military installations and activities. As an exception, neither blast nor fragment
criteria apply, when such facilities are located near AE support operations and used by off-duty
military or on-duty military or DoD civilians or contractors (e.g., munitions workers, security
guards, firefighters) who directly support these AE operations. However, when possible, such
facilities should fully comply with this Standard.

C9.4.1.1.4.4. Training areas (e.g., observation points, classrooms or other

instruction areas for ranges, and similar fixed facilities designed for occasional use coincident
with the use of the range). As an exception, to allow for realism in training, this separation does
not apply to AE needed for any particular exercise or on-the-job training. However, this
separation or equivalent protection is required from permanent PES and AE supply points.

C9.4.1.1.4.5. Open-air aircraft passenger loading and unloading areas.

C9.4.1.1.4.6. Parking lots for administrative areas. (Minimum fragment

distances apply, see subparagraph C9.4.1.2.)

C9.4.1.1.4.7. Inert storage located in the open (no structures involved) when not
directly related to the explosives mission and when accessed by personnel not directly related to
the explosives mission. (See subparagraph C9.4.1.1.6.9. if located within a structure.)

C9.4.1.1.5. 1.7 psi [11.7 kPa] at 30W1/3 [11.9Q1/3]. Combat aircraft parking areas
exposed to AE storage and operating facilities.

C9.4.1.1.6. 1.2 - 0.90 psi [8.3 - 6.2 kPa] at 40 - 50W1/3 [15.87 - 19.84Q1/3].

C9.4.1.1.6.1. Inhabited buildings, administrative and housing areas.

C9.4.1.1.6.2. An installation boundary, unless the area outside the boundary

naturally prohibits access, is government land that is not open to the public, or access is restricted
and controlled by other means. When IBD QD arcs penetrate an installation’s boundary, the
Service shall certify IBD protection does not apply to the encumbered area and shall establish
procedures to monitor the area for any change in status.

C9.4.1.1.6.3. Recreation facilities (e.g., ball diamonds, golf courses, and

volleyball courts) that contain structures.

96 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.1.6.4. Flight-line passenger service functions (e.g., terminal buildings).

C9.4.1.1.6.5. Main powerhouses that provide vital utilities to a major portion of

an installation.

C9.4.1.1.6.6. Shops that by reason of their vital strategic nature, or high intrinsic
value of their contents, should not be placed at risk.

C9.4.1.1.6.7. Functions that, if momentarily put out of action, would cause an

immediate secondary hazard by reason of their failure to function.

C9.4.1.1.6.8. PTRD with high traffic density as described in subparagraph

C9.4.1.2.1.1.5.

C9.4.1.1.6.9. Inert storage located in a structure when not directly related to the
explosives mission and when accessed by personnel not directly related to the explosives
mission. (See subparagraph C9.4.1.1.4.7. if no structure is involved.)

C9.4.1.2. Minimum Fragment Distances

C9.4.1.2.1. The minimum distance for protection from hazardous fragments shall be
based on primary and secondary fragments from the PES and the population or traffic density of
the ES. It is defined as the distance at which the density of hazardous fragments becomes 1 per
600 ft2 [55.7 m2]. (This distance is not the maximum fragment range.) DDESB-approved
analyses and/or approved tests may be used to determine minimum distances for both primary
and secondary fragments. DDESB TP No. 13 (Reference (o)) is an example of a method to
determine minimal distances for building debris, while DDESB TP No. 16 (Reference (p))
provides similar information to determine minimal distances for primary fragments. In the
absence of appropriate analyses or tests, default hazardous debris distances apply:

C9.4.1.2.1.1. For populous locations provided IBD protection, the minimum

distance shall be the Hazardous Fragment Distance (HFD). If this distance is not known, the
following shall apply:

C9.4.1.2.1.1.1. For all types of Hazard Division 1.1 in quantities < 450 lbs
NEWQD [204 kg], the HFD shall be determined as follows (NOTE: PTRD is 60 percent of the
specified HFD):

C9.4.1.2.1.1.1.1. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM, use

“Earth-Covered Magazine” distances shown in Table C9.T1., as discussed in subparagraph
C9.4.1.3. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.2. For Hazard Division 1.1 in an Undefined ECM, where

the loading density = NEWQD (lbs)/internal volume (ft3) [English EQN C9.4-1] is < 0.028
lbs/ft3 [loading density = NEWQD/internal volume (m3) [Metric EQN C9.4-2] is < 0.449 kg/m3]

97 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

use “Earth-Covered Magazine” distances shown in Table C9.T1., as discussed in subparagraph

C9.4.1.3. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.3. For Hazard Division 1.1 in an Undefined ECM where

the loading density is > 0.028 lbs/ft3 [> 0.449 kg/m3], use “Earth-Covered Magazine - side and
rear” distances of Table C9.T1. and for front exposure, apply the greater of “Earth-Covered
Magazine – front” IBD distance of Table C9.T1. or the HFD from the “STRUCTURE” column
of Table C9.T2., for the NEW in the ECM. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.4. Where ECM, regardless of structural designation, have

been designed, analyzed, or tested to have a reduced IBD and have been approved by the
DDESB, use the approved IBD. ILD shall be IAW subparagraph C9.4.1.4.1.

C9.4.1.2.1.1.1.5. For Hazard Division 1.1 in a structure (excluding ECM)

capable of stopping primary fragments, but which can contribute to the debris hazard, use
hazardous debris and PTRD distances found in Table C9.T10. ILD shall be IAW subparagraph
C9.4.1.4. Structures that are capable of stopping primary fragments include all Heavy Wall (H)
and Heavy Wall/Roof (H/R) AGS, as defined in the legend for Table C9.T8. Doors and other
openings through which primary fragments could exit must be capable of stopping primary
fragments from exiting the facility or shall be barricaded IAW section C5.3. to trap primary
fragments that could exit the facility.

C9.4.1.2.1.1.1.6. For Hazard Division 1.1 in the open or in a structure

incapable of stopping primary fragments, use HFD listed in the “OPEN” column of Table C9.T2.
ILD shall be IAW subparagraph C9.4.1.4. Structures (other than ECM) that are capable of
stopping primary fragments include all H and H/R AGS, as defined in the legend for Table
C9.T8. All other structures (other than ECM) are considered incapable of stopping primary
fragments.

C9.4.1.2.1.1.1.7. Selected items have been evaluated for minimum HFD

with results shown in Table C9.T3. Other items, through testing, have been hazard classified
with a specific HFD presented in the format HD (xx)1.1. The HFD for these items is specified in
hundreds of feet (in parenthesis), and they may not be listed in Table C9.T3. The distances for
these two categories of select items apply only to items in the open. When in facilities,
secondary debris as well as primary fragments must be considered. If in a facility that can
contain primary fragments, apply criteria of subparagraphs C9.4.1.2.1.1.1.1. through
C9.4.1.2.1.1.1.5. If in a facility that cannot stop primary fragments, use the greater distance from
Table C9.T3. (for the item being considered) or the HFD associated with the (xx)(1.1) item or
from Table C9.T2. for determining the applicable HFD. ILD shall be IAW subparagraph
C9.4.1.4.

C9.4.1.2.1.1.1.8. For bare explosives in the open, distance is computed by

the formula d=40W1/3 [15.87Q1/3]. [English EQN C9.4-3] [Metric EQN C9.4-4]

98 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.2.1.1.2. For Hazard Division 1.1 NEWQDs in the range 451 to

30,000 lbs [205 to 13,608 kg], HFD shall be determined according to the below criteria. PTRD
is 60 percent of the specified HFD, and ILD shall be IAW subparagraph C9.4.1.4.

C9.4.1.2.1.1.2.1. The minimum HFD shall be 1,250 ft [381 m], as shown

in Table C9.T1. Lesser distances are permitted if supported by a structural analysis. Facilities
sited at 1,235 ft [376 m] or 1,245 ft [380 m] per past standards shall be considered to be in
compliance with the 1,250 ft [381 m] minimum requirement.

C9.4.1.2.1.1.2.2. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM, use

“Earth-Covered Magazine” distances shown in Table C9.T1., as discussed in subparagraph
C9.4.1.3.

C9.4.1.2.1.1.2.3. For Hazard Division 1.1 in an Undefined ECM, where

the loading density is < 0.028 lbs/ft3 [< 0.449 kg/m3], use “Earth-Covered Magazine” distances
shown in Table C9.T1., as discussed in subparagraph C9.4.1.3.

C9.4.1.2.1.1.2.4. For Hazard Division 1.1 in an Undefined ECM with

minimum internal dimensions of 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Earth-
Covered Magazine - side and rear” distances of Table C9.T1. and “Other PES” distance of Table
C9.T1. for the front exposure.

C9.4.1.2.1.1.2.5. For Hazard Division 1.1 in an Undefined ECM where

the loading density is > 0.028 lbs/ft3 [> 0.449 kg/m3] and internal dimensions are less than 26 ft
[7.92 m] wide and 60 ft [18.29 m] long, use “Other PES” distances of Table C9.T1. for front,
side, and rear exposures.

C9.4.1.2.1.1.2.6. Selected items have been evaluated for minimum HFD

with results shown in Table C9.T3. Other items, through testing, have been hazard classified
with a specific HFD presented in the format HD (xx)1.1. The HFD for these items is specified in
hundreds of feet (in parenthesis), and they may not be listed in Table C9.T3. The distances for
these two categories of select items apply only to items in the open. When these items are placed
in a facility, apply the criteria of subparagraphs C9.4.1.2.1.1.2.1. through C9.4.1.2.1.1.2.5. as
appropriate.

C9.4.1.2.1.1.2.7. For bare explosives in the open, distance is computed by

the formula d=40W1/3 [15.87Q1/3]. [English EQN C9.4-3] [Metric EQN C9.4-4]

C9.4.1.2.1.1.3. For Hazard Division 1.1 NEWQDs > 30,000 lbs [13,608 kg]
HFD will be in accordance with Table C9.T1. Lesser distances are permitted if supported by a
structural analysis. PTRD is 60 percent of HFD and intraline criteria will be in accordance with
subparagraph C9.4.1.4. The following apply to use of the reduced “Earth-Covered Magazine”
distances shown in Table C9.T1., for the NEW range between 30,000 lbs [13,608 kg] and
250,000 lbs [113,398 kg]

Notes for Table C9.T1. (see subparagraph C9.4.1.2.1.1.):

1. For NEWQD < 45,000 lbs [20,412 kg], the distance is controlled by fragments. When fragments are absent or
if the HFD (1/600 ft2 [1/55.7 m2]) is less than the blast hazard range, then the blast criteria in this note may be
used.

Notes for Table C9.T3.:

1. Ten units or more until the point is reached at which this distance is exceeded by the distance requirements of
Table C9.T1.
2. Use the distance shown only where there are less than 25 unrelated people exposed in any arc encompassing 45
degrees from 900 ft [274 m] to 1250 ft [381 m] from the PES.
3. More than 10 units may be involved before 1250 ft [381 m] is exceeded. For distances involving more than 10
units consult the applicable Service guidance.
4. When handling more than one missile, the missiles must be transported or handled in a nose-to-tail
configuration and in their launch capsule or shipping container; furthermore, they must be aligned and/or
handled so that each group of two missiles is located outside of the warhead fragment beam spray region of the
other two missiles.

General Comments for Table C9.T3.:

(a) Items identified by an asterisk “*” include fragments from shipping or storage container(s). However, all of the
HFD in this table may be applied to both packaged and unpackaged configurations.
(b) Those items with WAU-17 warhead.
(c) 105-mm projectiles and 105-mm complete rounds not in standard storage or shipping containers are HD 1.1.
(d) All models, including Advanced Capability (ADCAP).
(e) These distances must be used when handling torpedo(es) from motor vehicles where sandbag (or other
equivalent) shielding (as described in Note (f)) is not present between the leading edge of the torpedo(es)
warhead and the motor vehicle engine compartment/crew cab to prevent the engine compartment/crew cab from
contributing to the debris.
(f) These distances may be used when handling torpedo(es) from:
(i) Motor vehicles with sandbag (or other equivalent) shielding between the leading edge of the torpedo(es)
warhead and the motor vehicle engine compartment/crew cab to prevent the engine compartment/crew cab
from contributing to the debris, or
[NOTE: Sandbag shield requirement is equivalent to a minimum thickness of 2 ft [0.61 m] of sand
between the engine compartment/crew cab and the torpedo(es). The sandbags must shield all parts of the
engine compartment/crew cab from the torpedo warhead.]
(ii) Other means of transport such as boats, torpedo transporters, forklifts, or portable cranes.

C9.4.1.2.1.1.3.1. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM,

where internal dimensions are a minimum of 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use
“Earth-Covered Magazine” distances shown in Table C9.T1.

C9.4.1.2.1.1.3.2. For Hazard Division 1.1 in a 7-Bar or a 3-Bar ECM,

where internal dimensions are less than 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Other
PES” distances of Table C9.T1. for front, side, and rear exposures.

C9.4.1.2.1.1.3.3. For Hazard Division 1.1 in an Undefined ECM, where

internal dimensions are a minimum of 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Earth-
Covered Magazine - side and rear” distances of C9.T1. and “Other PES” distance of Table
C9.T1. for the front exposure.

C9.4.1.2.1.1.3.4. For Hazard Division 1.1 in an Undefined ECM, where

internal dimensions are less than 26 ft [7.92 m] wide and 60 ft [18.29 m] long, use “Other PES”
distances of Table C9.T1. for front, side, and rear exposures.

C9.4.1.2.1.1.4. For sparsely populated locations (i.e., no more than 25

persons located in any sector bounded by the sides of a 45-degree angle, with the vertex at the

106 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

PES, and the 900 ft [274 m] and 1,250 ft [381 m] arcs from the PES), the minimum 1,250 ft [381
m] fragment distance may be reduced to 900 ft [274 m] if the NEWQD of the PES does not
exceed 11,400 lbs [5,171 kg].

C9.4.1.2.1.1.5. For PTR, the minimum fragment distance for HD 1.1 AE shall
be based on the traffic density considered at three levels: high, medium, and low traffic density.
The traffic density shall be averaged over a normal (non-holiday) week in terms of number of
passengers during a 24-hour period. Minimum fragment distance reductions based on sparse
population considerations addressed above, do not apply to public traffic routes. (NOTE: In
applying criteria other than the default values given below (which are based on car (and rail)
speed of 50 mph [80 kph], and a ship speed of 10 mph [16 kph]), considerations such as the
following shall be taken into account to establish exposure levels: speed of vehicles, number of
passengers per vehicle, protection afforded by the vehicle, variation in daily traffic levels in
relation to AE activities, and seasonal traffic trends. The default value of two passengers per car
may be used to estimate traffic density.

C9.4.1.2.1.1.5.1. High Traffic Density. If routes have 10,000 or more car

or rail passengers per day, or 2,000 or more ship passengers per day, then IBD criteria apply.

C9.4.1.2.1.1.5.2. Medium Traffic Density. If routes have between 400

and 10,000 car or rail passengers per day, or between 80 and 2,000 ship passengers per day, then
60 percent of the specified minimum fragment distance for IBD applies. As a minimum, these
criteria apply to any recreational activity that is extensive and occurs on a regular basis.

C9.4.1.2.1.1.5.3. Low Traffic Density. If routes have fewer than 400 car
or rail passengers per day, or fewer than 80 ship passengers per day, then no minimum fragment
distance is required. Minimum distance shall be based on blast criteria (24W1/3/30W1/3
[9.52Q1/3/11.9Q1/3]).

C9.4.1.2.1.1.5.4. For other exposures that are permitted at PTRD,

fragment distance minimal for HD 1.1 AE shall be at least 60 percent of the specified minimum
fragment distance for IBD.

C9.4.1.2.1.2. Minimum fragment distances apply to:

C9.4.1.2.1.2.1. An installation’s boundary unless the area outside the

boundary naturally prohibits access or is government land that is not open to the public. When a
QD arc extends beyond an installation’s boundary, and the above exclusion applies, the DoD
Component shall certify IBD protection need not be applied to the encumbered area and shall
establish procedures to monitor the area for any change in status.

C9.4.1.2.1.2.2. Administration and housing areas.

C9.4.1.2.1.2.3. Recreation facilities (e.g., ball diamonds, golf courses, and

volleyball courts). (See subparagraph C9.4.1.2.1.3.1. for situations where minimum fragment
distances do not apply to recreational facilities.)

107 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.2.1.2.4. Flight-line passenger service functions (e.g., terminal

buildings).

C9.4.1.2.1.2.5. Main powerhouses that provide vital utilities to a major

portion of an installation.

C9.4.1.2.1.2.6. Inert storage and shops that by reason of their vital strategic
nature, or high intrinsic value of their contents, should not be placed at risk.

C9.4.1.2.1.2.7. Functions that, if momentarily put out of action, would cause

an immediate secondary hazard by reason of their failure to function.

C9.4.1.2.1.2.8. Private vehicles parked in administrative areas.

C9.4.1.2.1.3. Examples when minimum fragment and firebrand distances need

not apply are:

C9.4.1.2.1.3.1. Recreation or training facilities when such facilities are

located near AE support operations and are used by off-duty military or on-duty military or DoD
civilians or contractors (e.g., munitions workers, security guards, and firefighters) who directly
support these AE operations.

C9.4.1.2.1.3.2. Related and support DoD-controlled functions for which IMD

and ILD would normally apply.

C9.4.1.2.1.3.3. Maintenance, supply, training facilities, and operations offices

for logistical or operational support of combat aircraft, battalion-size or smaller delivery or AE
supply units, separate air defense firing batteries, or a single pier or wharf for which the AE in a
PES is intended.

C9.4.1.2.1.3.4. Between a PES and inert storage, whether in a facility or in

the open.

C9.4.1.2.1.3.5. Between facilities in an operating line; between operating

lines; and between operating lines and storage locations.

C9.4.1.3. IBD and PTRD. Subparagraph C9.4.1.2.1.1. specifies required separation

distances to inhabited buildings and public traffic routes for ECM and other types of PESs
containing HD 1.1. Permissible exposures at these distances are listed in subparagraphs
C9.4.1.1.4. through C9.4.1.1.6.

C9.4.1.3.1. ECM. Specified separations from ECM consider reductions in blast

overpressure attributable to the earth cover of ECM, when the earth cover has a minimum
thickness of 2 ft [0.61 m]. See subparagraph C9.4.1.2.1.1. for application of “Earth-Covered

108 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

Magazine” distances of Table C9.T1. to 7-Bar, 3-Bar, and Undefined ECM. The definitions for
“front,” “side,” and “rear” for ECM are illustrated in Figure C9.F1. and are described below:

C9.4.1.3.1.1. The forward sector, or “front,” for ECM is that area 60 degrees
either side of the ECM’s centerline (120 degrees combined angle), with the vertex of the angle
placed so that the sides of the angle pass through the intersection of the headwall and sidewalls.

C9.4.1.3.1.2. The rear sector, or “rear,” of an ECM is that area 45 degrees either
side of the magazine centerline (90 degrees combined angle) with the vertex of the angle placed
so that the sides of the angle pass through the intersection of the rear and side walls.

C9.4.1.3.1.3. All other orientations are considered “side” sectors.

C9.4.1.3.2. HPM. Testing has shown that the design of the earth-bermed HPM
attenuates pressures relative to an unconfined surface burst similar to that indicated above for an
ECM. The following pertain to siting of an HPM:

C9.4.1.3.2.1. An HPM has a “front” sector and a “side” sector. The definition of
“front” for ECM (see subparagraph C9.4.1.3.1.1.) applies to an HPM. All other orientations are
considered “side” sectors. Figure C9.F8. illustrates the sectors associated with an HPM.
(NOTE: An HPM has no “rear” sector.)

C9.4.1.3.2.2. The values shown in Table C9.T4. for front exposure from an ECM
also apply to the front of an HPM.

C9.4.1.3.2.3. The values shown in Table C9.T4. for side exposure from an ECM
apply to the remainder (all but the front) of an HPM.

C9.4.1.4. ILD. Separation distances required between AE and non-AE buildings and
sites within an AE operating line are listed for various quantities of HD 1.1 AE in Table C9.T5.
Permissible exposures at ILD are listed in subparagraphs C9.4.1.1.1. (barricaded ILD) and
C9.4.1.1.2. (unbarricaded ILD). In order to apply barricaded ILD, barricades must comply with
paragraph C5.3.2. (The separation distance between an operating building and its service
magazine shall be based on the NEWQD and the HD of the AE in the magazine and not that in
other parts of the operating line.)

C9.4.1.4.1. ILD from ECM. Testing has shown that some attenuation of airblast
overpressure relative to an unconfined surface burst occurs out the sides and rear of an ECM and
a slight increase occurs out the front of an ECM. The equivalent 9W1/3 [3.57Q1/3] (12 psi [82.7
kPa] (barricaded)) and 18W1/3 [7.14 Q1/3] (3.5 psi [24 kPa] (unbarricaded)) ILD from an ECM,
when accounting for this attenuation, are given in Table C9.T4. (Airblast forms the bases for the
equations given in the notes for Table C9.T4.)

C9.4.1.4.2. Barricaded ILD from an ECM. Subparagraph C9.4.1.5.4. provides

criteria for the application of barricaded ILD from an ECM.

109 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.4.3. ILD from HPM. The values shown in Table C9.T4. for front exposure
from an ECM also apply to front exposures from an HPM. The values shown in Table C9.T4.
for side exposure from an ECM apply to all other orientations of an HPM. (The side of an HPM
is considered barricaded, provided the earth barricading complies with the design drawing.)

C9.4.1.5. IMD. Magazines for HD 1.1 shall be separated one from another per Tables
C9.T6., C9.T7A., and C9.T7B. (NOTE: Table C9.T6. provides orientation relationships for
ECM and Tables C9.T7A. and C9.T7B. provide the actual separation distances.)

C9.4.1.5.1. Siting Rules. For examples of siting rules for various magazine
orientations see Figures C9.F1. through C9.F8.

C9.4.1.5.2. Barricaded IMD from ECM. Subparagraph C9.4.1.5.4. provides criteria

for the application of barricaded IMD from ECM.

C9.4.1.5.3. Other Factors Limiting ECM Storage. Other factors limiting ECM
storage include:

C9.4.1.5.3.1. Quantities above 500,000 lbs [226,795 kg] NEWQD in one ECM
are not authorized, except for energetic liquids.

C9.4.1.5.3.2. The 7-foot separation distance given in Table C9.T7A. for 100 lbs
[45.4 kg] NEWQD constitutes the minimum side-to-side magazine separation distance.

C9.4.1.5.4. Application of Barricaded ILD and Barricaded IMD from an ECM.

Figure C9.F7. illustrates the IMD relationships that can exist between an ECM and AGM and the
ILD relationships that can exist between an ECM and facilities permitted to be at ILD or
barricaded ILD from an ECM, when each contain HD 1.1 AE. Permissible exposures at ILD are
listed in subparagraphs C9.4.1.1.1. (barricaded ILD) and C9.4.1.1.2. (unbarricaded ILD). Siting
criteria for AGM are provided in Table C9.T6. The following criteria shall apply to the use of
barricaded IMD for AGM and for use of barricaded ILD:

C9.4.1.5.4.1. Front Sector of an ECM. Use of barricaded ILD or barricaded

IMD, as applicable, between an ECM and a facility located within the ECM’s front sector
requires that a properly constructed, intervening barricade be located between the ES and the
PES. This barricade must meet the construction and location criteria of section C5.3. If it does
not meet these criteria, then unbarricaded IMD or unbarricaded ILD, as applicable, shall be used
for siting purposes.

C9.4.1.5.4.2. Side and Rear Sectors of an ECM. If an ECM’s earth cover meets
all construction criteria of section C5.3., it will qualify as a barricade, and use of barricaded ILD
or barricaded IMD, as applicable, from the sides or rear of the ECM is permissible. Failure of
the ECM’s earth cover to meet these criteria shall require use of unbarricaded IMD or
unbarricaded ILD, as applicable, for siting purposes.

110 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.1.5.5. Application of Barricaded ILD and Barricaded IMD from an HPM.

Permissible exposures at ILD are listed in subparagraphs C9.4.1.1.1. (barricaded ILD) and
C9.4.1.1.2. (unbarricaded ILD). Siting criteria for HPM containing HD 1.1 are provided in
Table C9.T6. The following applies to an HPM:

C9.4.1.5.5.1. Front Sector of an HPM. Use of barricaded ILD or barricaded

IMD, as applicable, between an HPM and a facility located within the HPM’s front sector
requires that a properly constructed, intervening barricade be located between the ES and the
PES. This barricade must meet the construction and location criteria of section C5.3. If it does
not meet these criteria, then unbarricaded IMD or ILD, as applicable, shall be used for siting
purposes.

C9.4.1.5.5.2. Side Sector of an HPM. If the earth berm surrounding an HPM

meets all construction criteria shown on the DDESB-approved construction drawing, it will
qualify as a barricade and use of barricaded ILD or barricaded IMD, as applicable, from the
HPM’s sides is permissible. Failure to meet these criteria shall require use of unbarricaded IMD
or unbarricaded ILD, as applicable, for siting purposes.

C9.4.1.5.6. These IMD standards apply only to storage of HD 1.1 AE. Existing
ECM, regardless of orientation, that meet the construction and barricading requirements of
Chapter 5 and are sited one from another for a minimum of 100 lbs [45.4 kg] NEWQD of HD
1.1 may be used to their physical storage capacity for HD 1.2, HD 1.3, and HD 1.4 AE, provided
distances to other exposures comply with applicable QD requirements.

Notes for Table C9.T6.:

1. Descriptions of ECM are in paragraph C5.2.1.
2. AGM are all types of above grade (non-earth-covered) magazines or storage pads.

118 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

3. A description of an HPM can be found at paragraph C5.2.4. Additional information is provided in

subparagraph C9.4.1.3. The MCE in an HPM is limited to a maximum of 60,000 lbs [27,216 kg].
4. The unbarricaded front (entrance to loading area) is a factor when the HPM is the PES because the MCE
includes AE in the loading area. The hazard factors have been determined accordingly.
5. Those barricades serve to mitigate both fragments and overpressure hazards. (See section C5.3. for their
requirements.)
6. Use this K-factor for NEWQD in PES up to 250,000 lbs [113,398 kg].
7. Use this K-factor for NEWQD in PES greater than 250,000 lbs [113,398 kg].
8. Modules and/or cells are defined in paragraph C5.2.2.
9. The storage areas in the HPM are barricaded on all sides and protected by a reinforced concrete cover. All
directions are, therefore, considered to be Side (S) orientations when it is the ES. For siting purposes, an HPM
has no Rear (R) sector. See Figure C9.F8. for an illustration of the front and side sectors of an HPM.

C9.4.2. HD 1.2

C9.4.2.1. General

C9.4.2.1.1. HD 1.2 are items configured for storage and transportation that do not
mass detonate when a single item or package in a stack is initiated. Explosions involving the
items result in their burning and exploding progressively with no more than a few at a time
reacting. These reactions will project fragments, firebrands, and unexploded items from the
explosion site. Blast effects are limited to the immediate vicinity and are not the primary hazard.

C9.4.2.1.2. Small quantities of HD 1.2.1 (< 450 pounds NEWQD [204 kg],), in
certain packaging configurations, will react in a manner more typical of an HD 1.1 event. When
located in structures that stop primary fragments, but which generate a secondary debris hazard
(e.g., certain ECM and hardened structures), the structural damage and debris hazards produced
from these events are more characteristic of an HD 1.1 explosion, rather than the progressive
nature of an HD 1.2.1 event. When the NEWQD and the MCE of the packaged HD 1.2.1 items
fall within the ranges specified in equation {NEWQD < MCE < 450 lbs [204 kg]}, the HD 1.2.1
shall be treated as HD 1.1 and the criteria of subparagraph C9.4.1.2.1.1.1., as applicable, shall be
used. If they fall outside the ranges of the equation, then the criteria of Table C9.T8. shall be
applied.

C9.4.2.2. The NEW of an HD 1.2 item (used for transportation) is the sum of the weight
of the HD 1.1 and 1.3 material contained within the item. The NEWQD for an item is equal to
NEW (NEWQD = NEW) unless testing has been conducted. Based on testing, the NEWQD
may include a reduced contribution (less than or equal to 100 percent) from the HD 1.3 material
as a result of the HD 1.1 material being functioned. The NEWQD should be determined by the
Single Package Test (UN Test 6 (a) or its equivalent), not the Bonfire Test (UN Test 6 (c)). The
NEWQD for a specific item may be obtained from the JHCS. The effects produced by the
functioning of HD 1.2 items vary with the size and weight of the item. HD 1.2 AE is separated
into two subdivisions in order to account for the differences in magnitude of these effects for
purposes of setting QD criteria. The more hazardous items are referred to as HD 1.2.1 items.
The less hazardous items are referred to as HD 1.2.2. These two HD 1.2 subdivisions are shown
below with their definitions (NOTE: It is important not to exaggerate the significance of the
value of 1.60 lbs [0.73 kg] used above. It is based on a break point in the database supporting
the quantity-distance relationships and tables and the NEWQD of the rounds tested. If
comprehensive data are available for a particular item, then the item may be placed in that
category of HD 1.2 supported by the data and allocated the relevant quantity-distances.):

C9.4.2.2.1. HD 1.2.1: NEWQD > 1.60 lbs [0.73 kg]

C9.4.2.2.2. HD 1.2.2: NEWQD < 1.60 lbs [0.73 kg]

C9.4.2.3. The MCE for HD 1.2.1 is the NEWQD of an item times the number of items in
three unpalletized, outer shipping packages, unless a different MCE is demonstrated by testing or
analogy. The authorized MCE for a specific HD 1.2.1 item is listed in the JHCS.

126 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.2.4. The QD specified for HD 1.2 AE achieve the desired degree of protection
against immediate hazards from an incident. Events involving HD 1.2 items lob large amounts
of unexploded rounds, components, and subassemblies, which will remain hazardous after
impact. Such items are likely to be more hazardous than in their original state because of
possible damage to fuze safety devices or other features by heat and impact. Many types of AE
containing sub-munitions, such as cluster bombs, can be expected to be projected out to distances
as great as the relevant inhabited building distances. Furthermore, it is impractical to specify
quantity distances, which allow for the maximum possible flight ranges of propulsive items.

C9.4.2.5. Table C9.T8. provides a summary matrix of all the appropriate IBD, PTRD,
and ILD separations for HD 1.2.1 and HD 1.2.2 AE, for the various combinations of ES and
PES. When HD 1.2.1 items are stored in structures that may contribute to the debris hazard, the
IBD is determined by using the larger of the following two distances: either that given in Table
C9.T9. for the appropriate Explosive Weight (number of items x NEWQD) or that given in Table
C9.T10. for the appropriate MCE. (Hazardous Debris Distance (HDD) specified in Table
C9.T10. equates to IBD.)

C9.4.2.6. IMD are dependent upon the types of structures acting as both the PES and the
ES.

C9.4.2.7. PTRD given in Tables C9.T8. through C9.T11. give consideration to the
transient nature of the exposure in the same manner as for HD 1.1. PTRD is computed as 60
percent of the IBD for items in this HD, with minimum distances specified in Table C9.T8.

C9.4.2.8. ILD given in Tables C9.T8. through C9.T11. take into account the progressive
nature of explosions involving these items (normally resulting from fire spread), up to the
magnitude of the MCE, and the ability to evacuate personnel from endangered areas before the
progression involves large numbers of items. Exposed structures may be extensively damaged
by projections and delayed propagation of explosions may occur due to the ignition of
combustibles by projections. ILD is computed as 36 percent of the IBD for items of this HD,
with a minimum distance equal to the IMD given in Table C9.T8. for the applicable PES-ES
combination.

C9.4.2.9. When storing mixed subdivisions of HD 1.2 AE (HD 1.2.1 and HD 1.2.2), the
following rule shall apply: Consider each subdivision separately and apply the greater of the two
distances. The general mixing rules for HD 1.2 AE are given in Table C9.T12.

C9.4.2.10. For reasons of operational necessity, limited quantities of HD 1.2.2 items may
be stored in facilities such as hangars, troop buildings, and manufacturing or operating buildings
without regard to quantity distance. Fragmentation shielding shall be provided.

C9.4.2.11. HD 1.2.3 is a special storage subdivision for HD 1.2 AE (see subparagraph

C3.2.1.2.3.).

127 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.2.12. The IBD for HD 1.2.3 is determined using Table C9.T13. (HD 1.3 QD) for
the NEWQD of the HD 1.2.3 item multiplied by the number of rounds present, but with a
minimum IBD determined as follows:

Notes for Table C9.T8.:

1. Practical considerations such as firefighting and security will dictate specific separation distances as specified
by DoD Component.
2. ILD = 36 percent of IBD with a minimum distance equal to the IMD given in this table for the applicable PES-
ES combination.
3. PTRD = 60 percent of IBD with a minimum distance equal to the IMD given in this table for light structures,
open stacks, trucks, trailers, or rail cars. Such structures are designated as AGS (L).
4. For HD 1.2.1 items in any structure, truck, trailer, or railcar, use the larger of the two applicable values given in
Tables C9.T9. and C9.T10.; for HD 1.2.1 items in the open, use Table C9.T9.; for HD 1.2.2 items, use Table
C9.T11.
5. See subparagraph C9.4.2.12. for HD 1.2.3.
6. When the NEWQD and the MCE of the packaged HD 1.2.1 items fall within the ranges specified in equation
{NEWQD < MCE < 450 lbs [204 kg]}, the HD 1.2.1 shall be treated as HD 1.1 and the criteria of subparagraph
C9.4.1.2.1.1.1., as applicable, shall be used (see subparagraph C9.4.2.1.2.).

General Comments for Table C9.T8.:

129 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

(a) For PES-ES combinations where three distances are given: the first refers to a PES containing HD 1.2.1 AE
with an MCE < 100 lbs [45.4 kg]; the second to a PES containing HD 1.2.1 AE with an MCE > 100 lbs [45.4
kg]; and the third refers to a PES containing HD 1.2.2 AE. Where three IMD are given, the IMD from a PES
containing only HD 1.2.3 AE to an ES containing other than HD 1.2.3 is K11 [4.36] based on the NEWQD of a
single round of the largest (greatest NEWQD) HD 1.2.3 AE in the PES.
(b) For an ES containing only HD 1.2.3 items, the IMD from any PES to such an ES is 0 (Note 1).

PES-ES combination. For structures other than AGS (L) as either ES or PES, see Table C9.T8.

General Comments for Table C9.T9.:

(a) The QD criteria for HD 1.2.1 items are based on the hazards from primary fragments. When stored in structures
that may contribute to the debris hazard (secondary fragments), the IBD for HD 1.2.1 items whose MCE is
greater than 31 lbs [14.1 kg] is determined by using the larger of two distances: those given in this table for the
appropriate explosive weight or those given in Table C9.T10. for the appropriate MCE. Structures that may
contribute to the debris hazard for storage of HD 1.2.1 AE include: (a) all ECM frontal exposures (side and rear
exposures have fixed minimum distances for IBD); (b) all AGS, including heavy wall (H), heavy wall and roof
(H/R), and light (L) as defined in C9.T8., unless data/analyses are provided to show that the structural debris
contribution is less. Note that ILD and PTRD are based on 36 percent and 60 percent, respectively, of the
applicable IBD as determined in this note with minimum distances of: ILD minimum distances are given in
Table C9.T8. for applicable PES-ES combinations and PTR minimum distances are given in Table C9.T8. for
AGS (L).

Notes for Table C9.T12.:

1. HD 1.2.1 distances given in Tables C9.T8., C9.T9, and C9.T10.
2. HD 1.2.2 distances given in Tables C9.T8. and C9.T11.
3. HD 1.2.3 distances given in Table C9.T13. (See subparagraph C9.4.2.12.)

C9.4.2.12.1. If the AE are in a structure that can interrupt primary fragments and can
contribute debris, the minimum IBD is the hazardous debris distance given in Table C9.T10. for
an MCE equal to the NEWQD of a single round.

C9.4.2.12.2. If the AE are in the open or in a light structure that will not interrupt
primary fragments, the minimum IBD is the HFD based on the HD 1.1 hazardous fragment areal
number density criteria applied to a single HD 1.2.3 item. The HFD applicable to AE in the
open is specified in hundreds of ft in parentheses as “(xx) HD 1.2.3.”

C9.4.2.12.3. As an alternative to the preceding HD 1.2.3 QD criteria, when an

increase in the allowable quantity or a reduction in the required distance will result, HD 1.2.3 AE
may be treated as follows:

C9.4.2.12.3.1. If the single-round NEWQD is > 1.6 lbs [0.73 kg], consider the
items as HD 1.2.1. Use the total NEWQD present, with an MCE equal to the NEWQD of one
round to determine the maximum QD.

C9.4.2.12.3.2. If the single-round NEWQD is < than 1.6 lbs [0.73 kg], consider
the items as HD 1.2.2, based on the total NEWQD present.

C9.4.2.13. For storage of mixed HD 1.2.3 AE, multiply the NEWQD for the HD 1.2.3
items by the corresponding number of HD 1.2.3 rounds and use Table C9.T13. with the HFD for
the mixture based on the largest HFD for the HD 1.2.3 AE in storage. Use the distances given in
Table C9.T12., when HD 1.2.3 AE is located with any other HD 1.2 sub-division. The HD 1.2.3
AE is considered HD 1.2 (HD 1.2.1 or HD 1.2.2, according to NEWQD) for QD purposes, when
HD 1.2.3 AE is located with any other HD AE. The mixing rules provided in paragraph C9.2.2.
then apply to the combination of the hazard divisions.

139 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.4.3. HD 1.3. HD 1.3 includes items that burn vigorously with little or no possibility of
extinguishment in storage situations. Explosions normally will be confined to pressure ruptures
of containers and will not produce propagating shock waves or damaging blast overpressure
beyond the magazine distance specified in Table C9.T13. A severe hazard of spread of fire may
result from tossing about of burning container materials, propellant, or other flaming debris.

C9.4.4. HD 1.4

C9.4.4.1. HD 1.4 AE present a fire hazard with minimal blast, fragmentation, or toxic
hazards. Separate facilities for storage and handling of these AE shall be located IAW Table
C9.T14.

C9.4.4.2. In mixed storage, the NEWQD of HD 1.4 is not additive (see subparagraph
C9.2.2.1.1.). However, QD criteria for each HD present, including HD 1.4, must be determined
and the largest value shall be used.

C9.4.4.3. HD 1.4S AE (see paragraph C2.5.5.) may be stored (including associated

handling) without regard to the QD criteria in Table C9.T14.

C9.4.5. HD 1.6. QD separations for HD 1.6 AE shall be based on the storage location and
configuration. This information is detailed in Table C9.T15. and its footnotes. A maximum of
500,000 lbs [226,795 kg] NEWQD shall be permitted at any one location. Any special storage
configuration and siting approved for HD 1.1 AE may be used for storage of like explosive
weights of HD 1.6 AE.

C9.4.6. HD 6.1

C9.4.6.1. HD 6.1 includes items that contain only toxic chemical or riot control agents.
AE containing both explosives and toxic chemical or riot control agents may be hazard classified
as HD 1.1 through HD 1.4, based on testing IAW Reference (e).

C9.4.6.2. Hazard zones for toxic chemical agents are determined by the relative toxicity
of the agents, the amount released to the atmosphere and the rate at which they are released (that
is, evaporation, pressure, or explosive dispersal), terrain features, and meteorological conditions.
Hazard zone calculations are based on MCE, using DDESB TP No. 10 (Reference (q)). (See
Chapter 11 for specific criteria associated with toxic chemical agents.)

C9.4.6.3. When siting AE containing toxic chemical agents, both the explosives and
toxic chemical agent hazards shall be evaluated with the greatest QD governing siting.

General Comments for Table C9.T13.:

(a) For reasons of operational necessity, limited quantities of items in this hazard division, such as document
destroyers, signaling devices, riot control munitions and the like, may be stored without regard to QD IAW fire
protection regulations in facilities such as hangars, arms rooms, and manufacturing or operating buildings.
(b) ECM may be used to their physical capacity for this HD provided they comply with the construction and siting
requirements of Chapters 5 and 9, respectively, for HD 1.1. ECM used to store only HD 1.3 items must be sited
for a minimum of 100 lbs [45.4 kg] of HD 1.1 items using Tables C9.T4. (ILD) and C9.T6. (IM). Use IBD and
PTRD columns of Table C9.T13. for determining the IBD and PTRD associated with the HD 1.3 being placed
in such ECM.

Notes for Table C9.T14.:

1. Magazines storing only HD 1.4 AE may be located at these IMD or ILD from all other magazines or operating
buildings regardless of the HD or NEWQD authorized in those adjacent structures. Because the HD 1.4 AE
may be destroyed as the result of an accident involving the assets in those adjacent structures, the DoD
Component on a case-by-case basis must accept application of this provision with consideration given to the
value of HD 1.4 assets at risk.
2. HD 1.4 AE may be stored in a general supplies warehouse area rather than in an AE storage area. When storing
in a general supplies warehouse area, any weatherproof warehouse structure may serve as an HD 1.4 magazine.
Such a structure will be separated from all other warehouses by AGM distance.
3. For reasons of operational necessity, limited quantities of HD 1.4 AE (e.g., small arms AE and riot control
munitions) may be stored within facilities (e.g., hangars, arms rooms, and operating buildings) without regard to
QD. Alternatively, operationally necessary HD 1.4 AE may be stored in small magazines external to those
facilities without regard to QD.
4. See subparagraph C9.2.2.1.1. for the applicability of HD 1.4 QD criteria and the determination of NEWQD
when HD 1.4 and other HD AE are located in the same site.

DoD 6055.09-STD, February 29, 2008

C9.5. ENERGETIC LIQUIDS

C9.5.1. Scope and application

C9.5.1.1. This section applies to the storage of energetic liquids, listed in Table C9.T16.,
in all types of containers, including rocket and missile tankage. Laboratory quantities shall be
stored and handled as prescribed by the controlling DoD Component. (NOTE: The required QD
are only based on the energetic liquids’ energetic reaction (blast overpressure and container
fragmentation). These QD requirements do not consider the toxicity or potential down-wind
hazard. Therefore, QD may not be the only factor that needs to be considered when selecting a
location for storage and operations of energetic liquids.)

C9.5.1.2. This section does not govern the storage or handling of energetic liquids for
uses other than in space launch vehicles, rockets, missiles, associated static test apparatus, and
AE.

C9.5.2. Concept

C9.5.2.1. These QD Standards were developed on the premise that the controlling DoD
Component shall ensure that the materials of construction are compatible with the energetic
liquids, facilities are of appropriate design, fire protection and drainage control techniques are
employed, and other specialized controls (e.g., nitrogen padding, blanketing, and tank cooling)
are used, when required.

C9.5.2.2. When additional hazards associated with AE are involved, the safety distances
prescribed in other sections of this Standard shall be applied, as required.

C9.5.2.3. These Standards are based upon the estimated credible damage resulting from
an incident, without considering probabilities or frequency of occurrence.

C9.5.3. Determination of energetic liquids quantity

C9.5.3.1. The total quantity of energetic liquids in a tank, drum, cylinder, or other
container shall be the net weight of the energetic liquids contained therein. Quantity of energetic
liquids in the associated piping must be included to the points that positive means are provided
for interrupting the flow through the pipe, or interrupting a reaction in the pipe in the event of an
incident.

C9.5.3.2. When the quantities of energetic liquids are given in gallons [liters], the
conversion factors given in Table C9.T17. may be used to determine the quantity in pounds [kg].

C9.5.4. Measurement of separation distances

C9.5.4.1. Measure from the closest controlling hazard source (e.g., containers, buildings,
segment, or positive cutoff point in piping).

147 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.5.4.2. Measure from the nearest container or controlling subdivision, when buildings
containing a small number of cylinders or drums are present or when quantities of energetic
liquids are subdivided effectively.

Notes for Table C9.T16.:

1. Flammable or combustible liquid classification index based on flash point and boiling point versus criteria as
specified in 29 CFR 1910.106 Occupational Safety and Health Standards (Reference (r)) and NFPA 30
Flammable and Combustible Liquids Code (Reference (s)). Primary descriptor is a Roman numeral, possibly
with an additional letter.
2. NFPA oxidizer classification index as described in NFPA 430 Code for the Storage of Liquid and Solid
Oxidizers (Reference (t)). Descriptor is an ordinary number.
3. Positive measures for spill containment/control shall be taken for isolated storage of energetic liquids IAW
applicable Occupational Safety and Health Administration (OSHA) and NFPA guidance (referenced in Tables
C9.T19. through C9.T21.). For flammable energetic liquids and liquid oxidizers where only minimum blast or

148 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

fragment distances are specified, applicable OSHA and/or NFPA guidance referenced in Tables C9.T19. and
C9.T20., respectively, should also be used.
4. Hydrogen peroxide solutions of concentration greater than 91 percent are NFPA Class 4 oxidizers.
5. Should be used as a default value, unless otherwise hazard classified, when the material is packaged in small
(non-bulk) shipping containers, portable ground support equipment, small aerospace flight vehicle propellant
tanks, or similar pressure vessels that provide heavy confinement (burst pressure greater than 100 psi [690
kPa]).
6. Should be used as a default value, unless otherwise hazard classified, when the material is packaged in small
(non-bulk) shipping containers (DoT 5C or equivalent), portable ground support equipment, small aerospace
flight vehicle propellant tanks, or similar pressure vessels providing a lower level of confinement (burst
pressure less than or equal to 100 psi [690 kPa]) and if adequate protection from fragments is not provided from
terrain, effective barricades, nets, or other physical means (lightweight building construction is not adequate).
If protection from fragments is provided, use the IBD/PTRD “Protected” column of Table C9.T22.
7. For large ready, bulk, or rest storage tanks (as defined in subparagraphs C9.5.5.7., C9.5.5.9., and C9.5.5.10.),
use Table C9.T22.
8. Where there is a reasonable risk of vapor cloud explosion of large quantities (for example, in bulk tank storage).
9. Technical grade nitromethane in unit quantities of 55 gallons [208.2 liters] or less in DoT-approved containers
listed in 49 CFR 173.202 (Reference (e)) may be stored as flammable liquids (Table C9.T19.) provided the
following apply:
a. Packages are stored only one tier high.
b. Packages are protected from direct rays of the sun.
c. Maximum storage life of 2 years, unless storage life tests indicate product continues
to meet purchase specification. Such tests are to be repeated at 1-year intervals thereafter.
10. For underwater static test stands, when operated at hydrostatic pressure above 50 psig [345 kPa], or for
propellant tanks or other vessels having burst pressures of greater than 100 psig [690 kPa] without acceptable
pressure relief devices (unless otherwise hazard classified). For underwater test stands, the TNT equivalence
(i.e., MCE) should include the total energetic liquids weight in all pumps and plumbing, as well as the weight of
energetic liquids held in tankage (under the test cell hydrostatic pressure) unless acceptable mitigation measures
such as fuel line detonation arrestors and/or fuel tank isolation/barricading are used (as determined by hazard
analysis).
11. Should be used as a default value, unless otherwise hazard classified, when the material is packaged in small
vehicle propellant tanks, small (non-bulk) shipping containers, portable ground support equipment, or similar
pressure vessels that provide relatively heavy confinement (burst pressure between 50 – 100 psig [345 – 690
kPa]) without acceptable pressure relief devices.
12. NG is Nitroglycerin, TMETN is Trimethylolethane Trinitrate, DEGDN is Diethyleneglycoldinatrate, TEGDN is
Triethylene Glycol Dinitrate, and BTTN is Butane-Trio-Trinitrate.

AE stores, but incompatible with each other, a two-part compatibility group designation is
assigned to an energetic liquid. (The design and logistics of modern weapons sometimes require
that consideration be given to permitting storage or operations involving energetic liquids in a
storage structure containing solid explosives. For example, it may be necessary to store
hydrocarbon-fueled cruise missiles having high explosive warheads with fueled configurations
not containing explosive warheads. Another example is the storage of liquid gun propellant with
explosive AE components.)

C9.5.5.2.1. The first element is the standard storage and transportation CG

designation. The alpha designations are the same as the CG designations for UN Class 1 as
given in Chapter 3. However, for storage and handling on DoD facilities, a CG may also be
assigned to an energetic liquid in a Class other than Class 1. The absence of a CG indicates
incompatibility with solid explosives.

C9.5.5.2.2. The second element is a new Energetic Liquid Compatibility Group

(ELCG) designation. The ELCG applies to mixed storage of energetic liquids or AE containing

151 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

energetic liquids. The ELCG is specified in parentheses as the last element of the hazard
classification. The ELCG designations and definitions are:

C9.5.5.2.2.1. LA: Energetic liquids that are strong oxidizers, mainly of acidic
character. These materials may cause or contribute to the combustion of other material, possibly
resulting in serious flare fires or explosions. Includes, but is not limited to, nitrogen tetroxide
and Mixed Oxides of Nitrogen (MON), Inhibited Red Fuming Nitric Acid (IRFNA), liquid
oxygen (LO2), hydrogen peroxide (H2O2), and gels, slurries, or emulsions of these chemicals.

C9.5.5.2.2.2. LB: Energetic liquids that are readily combustible when exposed
to, or ignited in the presence of an oxidizing agent, but that are not strong reducing agents. Some
may be hypergolic with group LA materials. Includes, but is not limited to, hydrocarbons such
as kerosenes and strained ring ramjet fuels; liquid hydrogen (LH2); and gels, slurries, or
emulsions of these chemicals.

C9.5.5.2.2.3. LC: Energetic liquids that are readily combustible when exposed
to, or ignited in the presence of an oxidizing agent, and are also strong reducing agents. These
will likely be hypergolic with group LA substances. Includes, but is not limited to, hydrazines
and other amines; and gels, slurries, or emulsions of these chemicals.

C9.5.5.2.2.4. LD: Energetic liquids that act mainly as combustible fuels, similar
to groups LB and LC, when exposed to or ignited in the presence of oxidizing agents but that
may act as oxidizers in some combinations. They may be a monopropellant with the right
catalyst, or may be pyrophoric and ignite upon release to the atmosphere. Examples are boranes
and ethylene and propylene oxides.

C9.5.5.2.2.5. LE: Energetic liquids having characteristics that do not permit

storage with any other energetic liquid. They may react adversely with either fuels (reducing
agents) or oxidizers. Examples are nitromethane, nitrate ester-based formulations such as Otto
Fuel II, liquid monopropellants containing Hydroxyl Ammonium Nitrate (HAN); halogen
fluorides (ClF3 and ClF5) and fluorine; and gels, slurries, or emulsions of these chemicals.

C9.5.5.2.3. For mixing of energetic liquids:

C9.5.5.2.3.1. Different energetic liquids in the same ELCG may be stored

together.

C9.5.5.2.3.2. ELCG-LE may not be mixed with other ELCG or dissimilar ELCG-
LE.

C9.5.5.2.3.3. Mixed storage is prohibited between energetic liquids of different

ELCG designations with one exception.

C9.5.5.2.3.3.1. ELCG-LB and -LC should not be stored together, particularly

when the majority of the material stored is ELCG-LB; however, mixed storage of ELCG-LB and
-LC is permitted when operationally necessary.

152 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.5.5.2.4. As an example, for the 1.3C(LE) hazard classification for HAN-based

liquid gun propellant XM-46:

C9.5.5.2.4.1. “C”: indicates the propellant can be stored in the same magazine
with CG-C solid propellants. Because CG-C and CG-D can be mixed, CG-D high explosive
projectiles could also be stored with the energetic liquid gun propellant.

C9.5.5.2.4.2. “LE”: indicates that hydrocarbon fuels (e.g., Jet Propellant (JP)-10),
which is an ELCG-LB, would not be permitted in this storage scenario, because its ELCG-LB
indicates incompatibility with ELCG-LE.

C9.5.5.3. Complete DoD hazard classification assignments for current energetic liquids
are shown in Table C9.T16. (Conversions for gallons of energetic liquids to pounds is provided
in Table C9.T17.)

C9.5.5.4. Each new energetic liquid, or new non-bulk packaging configuration of an

energetic liquid, developed by a DoD Component or adopted for DoD use, must be examined
and assigned a hazard classification per Reference (d).

C9.5.5.5. A different minimum distance may be assigned during the hazard classification
process when the hazards of a particular new packaging configuration are not adequately
addressed. This distance shall be indicated parenthetically, in hundreds of feet, as the first
element of the hazard classification. For example, if a new liquid oxidizer pressure vessel
configuration is hazard classified as (04)2.2(LA), then a minimum distance of 400 ft [122 m]
would apply for IBD and PTRD, otherwise the prescribed liquid oxidizer QD criteria would
apply.

C9.5.5.6. The predominant hazard of the individual energetic liquids can vary depending
upon the location of the energetic liquid storage and the operations involved. These locations are
listed below in the order of decreasing hazards.

C9.5.5.6.1. Launch pads. Operations at these facilities are very hazardous because of
the proximity of fuel and oxidizer to each other, the frequency of launchings, lack of restraint of
the vehicle after liftoff, and the possibility of fallback with resultant dynamic mixing on impact.
To compute the equivalent explosive weight for the launch pad, use Table C9.T18. with the
combined energetic liquids weight in the launch vehicle tanks and any energetic liquids in piping
that are subject to mixing, except as indicated in subparagraph C9.5.5.8.

C9.5.5.6.2. Static test stands. Operations at these facilities are less hazardous
because test items are restrained and subject to better control than launch vehicles. As with
launch pads, the proximity of fuel and oxidizer presents a significant hazard. To reduce this
hazard, tankage should be separated and remotely located from the static test stand. The
equivalent explosive weights of Table C9.T18. shall be used, with the combined energetic liquids
weight subject to mixing as determined by hazard analysis. The amount of energetic liquids held

153 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

in run tanks can be excluded from consideration if the test stand meets all the following criteria,
if applicable:

C9.5.5.6.2.1. All tanks are American Society of Mechanical Engineers (ASME)

certified and maintained per ASME Code, section VIII, Division 1 or Division 2 (Reference (u)).

C9.5.5.6.2.2. For cryogenic propellants, all tanks are constructed with double
wall jacketing.

C9.5.5.6.2.3. Run tankage is protected from fragments produced by an engine

malfunction.

C9.5.5.6.2.4. Both the fuel and oxidizer lines contain two (redundant), remotely-
operated valves to shut off flow in the event of a malfunction.

Notes for Table C9.T18.:

1. The percentage factors given in the table are to be used to determine equivalent explosive weights of energetic
liquids mixtures at static test stands and range launch pads when such energetic liquids are located aboveground
and are unconfined except for their tankage. Other configurations shall be considered on an individual basis to
determine equivalent explosive weights.
2. The equivalent explosive weight calculated by the use of this table shall be added to any non-nuclear explosive
weight aboard before distances can be determined from Tables C9.T1. and C9.T5.
3. These equivalent explosive weights apply also for these substitutions:
Alcohols or other hydrocarbons for RP-1.
H2O2 for LO2 (only when LO2 is in combination with RP-1 or equivalent hydrocarbon fuel).
Monomethylhydrazine (MMH) for N2H4, Unsymmetrical Dimethylhydrazine (UDMH), or combinations of the
two.
4. For quantities of energetic liquids up to but not over the equivalent explosive weight of 100 lbs [45.4 kg] of AE,
the distance shall be determined on an individual basis by the DoD Component. All personnel and facilities,
whether involved in the operation or not, shall be protected by operating procedures, equipment design,
shielding, barricading, or other suitable means.
5. Distances less than intraline are not specified. Where a number of prepackaged energetic liquid units are stored
together, separation distance to other storage facilities shall be determined on an individual basis by the DoD
Component, taking into consideration normal hazard classification procedures.
6. For siting launch vehicles and static test stands, equivalent explosive weight is the larger of:
a. The weight equal to 8W 2/3 [4.13 Q2/3] where W is the weight of LO2/LH2; or
b. 14 percent of the LO2/LH2 weight.
NOTE: For these calculations, use the total weight of LO2/LH2 present in the launch vehicle, or the total weight
in test stand run tankage and piping for which there is no positive means to prevent mixing in credible accidents.
When it can be reliably demonstrated that the MCE involves a lesser quantity of energetic liquids subject to
involvement in a single reaction, the lesser quantity may be used in determining the equivalent explosive weight.
When siting is based on a quantity less than the total energetic liquids present, the MCE and associated explosive
yield analysis must be documented in an approved site plan (section C5.4.).
7. These are hypergolic combinations.

155 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

8. The equivalent explosive weight of the hybrid rocket system N2O4 liquid oxidizer combined with PBAN solid
fuel was evaluated as 15 percent for an explosive donor accident scenario, 5 percent for a high-velocity impact
scenario, and less than 0.01 percent (negligible) for static mixing (tower drop) failures (Air Force Rocket
Propulsion Laboratory AFRPL-TR-67-124 (Reference (v))).
9. See Note 10 of Table C9.T16.
10. See Note 8 of Table C9.T16.

C9.5.5.7. Ready storage is relatively close to the launch and static test stands; normally it
is not involved directly in feeding the engine as in the case with run tankage, which is an integral
part of all launch and test stand operations. The equivalent explosive weights of Table C9.T18.
shall be used with the combined energetic liquids weight subject to mixing if the facility design
does not guarantee against fuel and oxidizer mixing and against detonation propagation to, or
initiation at, the ready storage facility when an accident occurs at the test stand, on the ground at
the launch pad, or at the ready storage areas. Otherwise, fire and fragment hazards shall govern
(Tables C9.T16., C9.T19., C9.T20., C9.T21., and C9.T22.).

C9.5.5.8. Fire and fragment hazards govern (Tables C9.T16., C9.T19., C9.T20.,
C9.T21., and C9.T22.) if the design is such that the system is closed except for approved
venting; is completely airtight; fuel and oxidizer never are employed concurrently; and each has
a completely separate isolated system and fitting types to preclude intermixing, and the energetic
liquids are of required purity. Otherwise, equivalent explosive weights (Table C9.T18.) shall be
used with the combined energetic liquids weight.

C9.5.5.9. Bulk storage is the most remote storage with respect to launch and test
operations. It consists of the area, tanks, and other containers therein, used to hold energetic
liquids for supplying ready storage and, indirectly, run tankage where no ready storage is
available. Fire and fragment hazards govern (Tables C9.T16., C9.T19., C9.T20., C9.T21., and
C9.T22.) except in special cases as indicated in Tables C9.T16. and C9.T18.

C9.5.5.10. Rest storage is temporary-type storage and most closely resembles bulk
storage. It is a temporary parking location for barges, trailers, tank cars, and portable hold tanks
used for topping operations when these units actually are not engaged in the operation, and for
such vehicles when they are unable to empty their cargo promptly into the intended storage
container. Fire and fragment hazards govern (Tables C9.T16., C9.T19., C9.T20., C9.T21., and
C9.T22.) except in special cases as indicated in Tables C9.T16. and C9.T18. The transporter
becomes a part of that storage to which it is connected during energetic liquids transfer.

exceptions:
a. If the storage building is located at least 100 ft [30.5 m] from any exposed building (under the direct
jurisdiction of a fire protection organization) or property line; or
b. If the storage building is located at least 200 ft [61 m] from any exposed building (not under the direct
jurisdiction of a fire protection organization) or property line; or
c. For combustible liquids that will not exhibit sustained burning in bulk form, e.g. Otto Fuel II, as determined
through American Society for Testing and Materials (ASTM) D 92 Standard Test Method for Flash and Fire
Points by Cleveland Open Cup or comparable testing. Refer to Reference (r) and Reference (s) for further
guidance on liquid storage and fire protection.
4. For container storage inside of a building, IBD/PTR distances may be less than 50 ft [15.2 m] (to a minimum of
10 ft [3.05 m]) if the storage building is constructed of fire-resistive exterior walls having an NFPA fire
resistance rating of 2 hours or more, according to NFPA 251 Standard Methods of Tests of Endurance of
Building Construction Materials (Reference (w)).
5. For large tank storage, QD may be 25 ft [7.6 m] for tank capacities up to 100,000 gallons [378,541 liters], and
37.5 ft [11.4 m] for capacities between 100,001 gallons [378,545 liters] and 500,000 gallons [1,892,706 liters].
6. For flammable liquids container storage inside of a building, ILD/aboveground IMD is 50 ft [15.2 m] (except as
in Note 4), or for adjacent incompatible oxidizer storage, distances specified for energetic liquid oxidizers
(Table C9.T20.) or oxygen (Table C9.T21.). For flammable liquids storage in fixed or large portable tanks,
ILD/aboveground IMD is either (1) for compatible energetic liquids, equal to one-sixth of the sum of the
diameters of the two adjacent tanks, or distances specified in Note 5 for adjacent container storage inside of a
building; or (2) for adjacent incompatible oxidizer storage, distances specified for energetic liquid oxidizers
(Table C9.T20.) or oxygen (C9.T21.). ECM may be used to their physical capacity for storing flammable
energetic liquids provided they comply with the construction and siting requirements of Chapters 5 and 9,
respectively for HD 1.1. ECM must be sited for a minimum of 100 lbs [45.4 kg] of HD 1.1 items using Tables
C9.T4. and C9.T6.

Notes for Table C9.T22.:

1. Positive measures shall be taken to prevent mixing of hydrogen or hydrazines and adjacent oxidizers in the
event of a leak or spill.
2. Distances are necessary to provide reasonable protection from fragments of tanks or equipment that are
expected to be thrown in event of a vapor phase explosion.

4. The term “protected” means that protection from fragments is provided by terrain, effective barricades, nets, or
other physical means.

6. ILD/aboveground IMD distances in this column apply for adjacent compatible (ELCG LB or LC) storage; for
adjacent incompatible (other ELCG) storage, use IBD distances shown in previous columns. ECM may be used
to their physical capacity for storing hydrogen provided they comply with the construction and siting
requirements of Chapters 5 and 9, respectively for HD 1.1. ECM must be sited for a minimum of 100 lbs [45.4
kg] of HD 1.1 items using Tables C9.T4. and C9.T6.
7. Distances are 37.5 percent of “protected” column.
8. Extrapolations above 1,000,000 lbs [453,590 kg] extend well outside data included in Reference (y) from which
the original QD tables were derived; however, they are supported by independent calculations and knowledge of
like phenomena.

C9.5.5.11. Run tankage (operating tankage) consists of the tank and other containers and
associated piping used to hold the energetic liquids for direct feeding into the engine or device
during operation. The contents of properly separated “run tanks” (operating tankage) and piping
are normally considered on the basis of the pertinent hazards for the materials involved, except
for quantities of incompatible materials that are or can be in a position to become mixed.
Equivalent explosive weights shall be used (Table C9.T18.) for quantities of such materials
subject to mixing unless provisions of subparagraphs C9.5.5.6.2.1. through C9.5.5.6.2.4. are
satisfied.

C9.5.5.12. A 25-ft [7.6 m] clear zone to inhabited buildings shall be maintained, as a

minimum, on each side of pipelines used for energetic liquids (excluding flammable or
combustible liquids that exhibit normal fire hazards such as RP-1, JP-10, and Otto Fuel II).
Tables C9.T16., C9.T20., C9.T21., and C9.T22. apply, as appropriate.

C9.5.6. QD standards. Since many energetic liquids are not classified as UN Class 1
explosives, conventional QD storage criteria do not generally apply to these materials. At the

163 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

same time, the (non-Class 1) UN transportation hazard classifications for many energetic liquids
appear to be inappropriate and/or inadequate for application to storage safety (based on available
accident and test data). For example, hydrazine has a UN hazard classification of 8 (corrosive),
while it also is subject to dangerous fire and explosive behavior. Thus, the implementation of
QD criteria for energetic liquids is based on an independent determination of the predominant
hazard presented by the material in the storage environment. The following standards are
applicable to energetic liquids used for propulsion or operation of missiles, rockets, and other
related devices.

C9.5.6.1. Tables C9.T16., C9.T19., C9.T20., C9.T21., and C9.T22. provide minimum
distance requirements for storage of bulk quantities, and in some cases, pressure vessels and
other commercial packagings of energetic liquids. In general, the minimum distance required by
the material requiring the greatest distance shall separate storage of different energetic liquids.
In addition, positive measures shall be taken to control the flow of energetic liquids in the event
of a leak or spill, in order to prevent possible fire propagation or accumulation of flammable
liquids near other storage, and/or to prevent mixing of incompatible energetic liquids (except for
specific hazardous locations as identified in subparagraph C9.5.5.6. above). Equivalent
explosive weights apply for some materials as indicated in Tables C9.T16. and C9.T18.
Fragment hazards govern for some materials in certain packaging configurations. For the more
conventional fuels and oxidizers, and also where minimum blast and/or fragment criteria are not
required due to low confinement packaging, QD standards are adopted from OSHA and NFPA
guidelines to account for normal fire protection principles.

C9.5.6.2. For specific hazardous locations as defined in subparagraph C9.5.5.6. above,

equivalent explosive weights may apply. If so, consult Tables C9.T16. and C9.T18. with the
combined energetic liquids weight subject to mixing and use distances found in Table C9.T1. or
C9.T5. Enter the equivalent explosive weight in Table C9.T1. or C9.T5. QD standards for other
conditions and equivalent explosive weights for any combination not contained in Table C9.T16.
or C9.T18. shall be determined by the controlling DoD Component.

C9.5.7. Contaminated energetic liquids

C9.5.7.1. Caution shall be exercised in the storage and handling of contaminated

energetic liquids. Such contamination may increase the degree of hazard associated with the
energetic liquids.

C9.5.7.2. Energetic liquids known to be contaminated or in a suspect condition shall be

isolated and provided separate storage from all other energetic liquids pending laboratory
analysis for verification of contamination and disposition requirements, if any.

C9.6. SITING

C9.6.1. Airfields and Heliports.

C9.6.1.1. Scope and Application.

C9.6.1.1.1. This section:

164 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.1.1.1.1. Applies to AE that is under the control and custody of DoD

personnel at airfields and heliports. (Chapter 10 applies when these requirements cannot be met
for contingencies, combat operations, and military operations other than war.)

C9.6.1.1.1.2. Does not apply to AE installed on aircraft (e.g., egress system

components, squibs, and detonators for jettisoning external stores, engine-starter cartridges, fire
extinguisher cartridges, and destructors in electronic equipment), contained in survival and
rescue kits (e.g., flares, signals, explosives components of emergency equipment), and other such
items or materials necessary for safe flight operations.

C9.6.1.1.2. Aircraft parking areas.

C9.6.1.1.2.1. Uploading and downloading of AE shall be conducted at

explosives-sited aircraft parking areas.

C9.6.1.1.2.2. QD is not required for the following:

C9.6.1.1.2.2.1. Aircraft loaded with AE shown below and parked in

designated aircraft parking areas that meet airfield criteria when evaluated as a PES:

C9.6.1.1.2.2.1.1. HD 1.2.2: gun AE, 30 mm or less.

C9.6.1.1.2.2.1.2. HD 1.3: Captive missiles, aircraft defensive flares or

chaff.

C9.6.1.1.2.2.1.3. HD 1.4 AE.

C9.6.1.1.2.2.2. Uploading and downloading AE listed above (subparagraph

C9.6.1.1.2.2.1.), at a designated aircraft parking area, provided the quantity of AE involved in
the operation is limited to a single aircraft load.

C9.6.1.2. Additional Siting Criteria. This section’s QD criteria shall be applied with the
airfield clearance criteria that is prescribed by DoD Component and FAA regulations (14 CFR
Part 77 (Reference (z))). For airfields and heliports:

C9.6.1.2.1. Used exclusively by the DoD Components and allied nations’ military
components; combat aircraft parking areas, AE cargo areas, alert hangars, and shelters may be
located within the airfield clearance zone, the exception is in AE prohibited areas (see
subparagraph C9.6.1.7.).

C9.6.1.2.2. Not used exclusively by DoD Components and allied nations military
components; combat aircraft parking areas, AE cargo areas, alert hangars, and shelters shall be
located as prescribed in Tables C9.T23. and C9.T24. (Refer to Table C9.T24. first.)

165 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.1.3. Measurement of Separation Distances. In applying Tables C9.T23. and

C9.T24., distances shall be measured as follows:

C9.6.1.3.1. Loaded Aircraft to Loaded Aircraft. Measure the shortest distance

between AE on one aircraft to AE on the adjacent aircraft.

C9.6.1.3.2. AE Location to Taxiways and Runways. Measure from the nearest point
of the AE location to the:

C9.6.1.3.2.1. Nearest point of the taxiway.

C9.6.1.3.2.2. Centerline of the runway.

C9.6.1.4. Helicopter Landing Areas for AE Operations. Helicopter landing areas for
loading and unloading AE within storage sites and quick reaction alert sites shall be considered
AGM and may be sited at IMD based only upon the NEWQD carried by the helicopter. Such
helicopter landing areas shall meet the following requirements:

C9.6.1.4.1. Flight clearance criteria are met.

C9.6.1.4.2. Landing and takeoff approaches shall not be over any AE facilities.

C9.6.1.4.3. Helicopter operations are to be limited to AE support of the facilities

concerned.

C9.6.1.4.4. Carrying of passengers is not permitted.

C9.6.1.4.5. During helicopter takeoff, landing, or loading or unloading, AE

operations shall not be conducted at any PES located within IBD of the helicopter landing area.

3. For HD 1.1, use applicable IMD. For HD 1.2, apply Note 10. Protects against simultaneous detonation of AE
on adjacent aircraft, but does not prevent serious damage to aircraft and possible propagation of detonation due
to fragments, debris, or fire.
4. Use applicable ILD.
5. Use Table C9.T23. distances for mass-detonating items and applicable PTRD for nonmass-detonating items.

168 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

6. Use Table C9.T23. distances for DoD Component aircraft parking areas and applicable IBD for non-DoD entity
aircraft parking areas.
7. Use applicable PTRD for locations in the open where passengers enplane and deplane; use applicable IBD if a
structure is included where passengers assemble, such as a passenger terminal building.
8. No distance required to recreational areas that are used exclusively for alert personnel manning the
combat-loaded aircraft. Other recreational areas where people are in the open shall be at applicable PTRD.
When structures, including bleacher stands, are a part of such area, applicable IBD shall be used.
9. Recreational areas, where people are in the open, shall be at applicable PTRD. When structures, including
bleacher stands are part of such area, applicable IBD shall be used.
10. Within these areas of airfields and heliports exclusively used by the DoD Components, the separation of aircraft
parking areas from combat aircraft parking areas and their ready AE storage facilities and AE cargo areas are
considered to be a command function. At joint DoD/non-DoD use airfields and heliports, the combat aircraft
parking areas and its ready AE storage facilities and AE cargo area shall be separated from non-DoD aircraft as
specified in Note 6, above.
11. Use 18W1/3 [7.14Q1/3] distances from side or rear of ECM to taxiways; use PTRD from front of ECM or any
other storage locations to taxiways; and use PTRD from all storage location to runways.

C9.6.1.5. Hardened Aircraft Shelters (HAS).

C9.6.1.5.1. HAS and associated AE facilities shall be separated according to Table

C9.T25. At these distances there will be a high degree of protection against propagation of
explosion when HAS doors are properly secured. However, the exposed shelter may be
damaged heavily and aircraft and AE therein may be rendered unserviceable.

C9.6.1.5.2. HAS and associated AE facilities separated according to Table C9.T26.

will provide a higher degree of asset preservation than those provided in Table C9.T25. An
explosion in one shelter or ready storage facility may destroy it and its contents, but aircraft
within adjacent shelters will be undamaged provided the doors are closed. These aircraft may
not be immediately accessible due to debris.

C9.6.1.5.3. The front, side, or rear sectors of a HAS as either a PES or an ES are
defined in Figure C9.F9.

C9.6.1.5.4. For a third-generation HAS containing up to 11,000 lbs [4,989.5 kg]

NEWQD, use separation distances of Table C9.T27. to unhardened ES. The QD criteria given in
Table C9.T27. apply to all HD 1.1 AE, regardless of any minimum fragment distance denoted by
(xx) 1.1.

C9.6.1.5.5. When operational necessity dictates, as determined by the DoD

Component, separation distances less than those contained in Tables C9.T25. and C9.T26. may
be approved; however, it must be shown that equivalent protection is being provided.

1. Maintenance HAS shall not be located closer than 300 ft [91.4 m] from any PES HAS sited for more than 500
lbs [226.8 kg] NEWQD.
2. Second and Third generation HAS are limited to a maximum of 11,000 lbs [4,989.5 kg] NEWQD per shelter.

DoD 6055.09-STD, February 29, 2008

Notes for Table C9.T27.:

1. Separation distances are based on shelter doors remaining closed, except for aircraft towing, fueling, servicing,
run-up, or taxiing, and during integrated combat turnarounds or short periods when maintenance equipment or
munitions are being moved into or out of the shelter. Where doors are left open for extended periods, normal
combat aircraft parking area criteria of Table C9.T24. apply.
2. Separate AE from the HAS walls by a distance sufficient to prevent breaching. For less than 1,100 lbs [498.9
kg] NEWQD a 3-ft [0.91 m] separation from the wall is sufficient.
3. These QD criteria apply to IBD, PTRD, and ILD exposures for quantities < 1,100 lbs [498.9 kg] NEWQD.
4. For quantities > 1,100 to 11,000 lbs [498.9 to 4,989.5 kg] NEWQD, these QD only apply to IBD exposures. Use
50 percent of the IBD criteria for PTRD exposures with a 300 ft [91.4 m] minimum distance (out the front or
rear) or a 394 ft [120.1 m] minimum distance (off the sides). Use 35 percent of the IBD criteria for intraline
exposures with a 300-ft [91.4 m] minimum distance (out the front and rear) or a 394-ft [120.1 m] minimum
distance (off the sides).

C9.6.1.6. Combat Aircraft Support Facilities. See subparagraph C9.4.1.1.2.1.11. for

separation distance criteria associated with such facilities. When operational necessity dictates,
separation distances less than K18 [7.14] may be approved; however, it must be demonstrated
that K18 [7.14] equivalent protection is provided.

C9.6.1.7. AE Prohibited Areas. Areas immediately beyond the ends of runways and
along primary flight paths are subject to more aircraft accidents than other areas. For this reason,
AE is prohibited from Accident Potential Zones (APZ) I and II and Clear Zones (CZ) of all
aircraft landing facilities, as designated and described in detail in DoD Component airfield and
airspace criteria directives.

C9.6.2. Pier And Wharf Facilities

C9.6.2.1. Scope and Application. QD herein are for HD 1.1 AE. If only AE of other HD
are involved, the applicable QD shall be applied. This section:

C9.6.2.1.1. Applies to:

C9.6.2.1.1.1. Ship and barge units, hereafter referred to as ships.

C9.6.2.1.1.2. Piers and wharf and associated facilities at which AE may be

handled, or be present in ships’ holds or conveyances.

C9.6.2.1.1.3. Loading, off-loading, stowing, and shifting of AE from ships’

magazines.

C9.6.2.1.2. Does not apply (i.e., no QD required) to:

C9.6.2.1.2.1. AE in static storage in ships’ magazines and intended for the

service of shipboard armament or aircraft, provided the Service Secretary formally accepts any
explosives risk associated with such storage.

C9.6.2.1.2.2. Handling < 300 lbs [136.1 kg] NEWof combined HD 1.3 and HD
1.4 AE that are necessary for ship’s security and safety at sea.

173 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.2.2. Determining the Quantity of Explosives in a Ship

C9.6.2.2.1. The NEWQD on board a ship shall be determined per section C9.2.

C9.6.2.2.2. When ships are separated by 11W1/3 [4.36Q1/3] distances or greater, QD

shall be based individually on the quantity of each ship. Lesser separation distances require that
the AE in all ships be totaled.

C9.6.2.3. Measurement of Separation Distances

C9.6.2.3.1. Moored Ships

C9.6.2.3.1.1. Measurement of separation distances between ships or barges shall

be from the nearest point of one ship’s magazine (i.e., the PES) or the barge:

C9.6.2.3.1.1.1. For IMD: To the nearest point of another ship’s magazine or

a barge.

C9.6.2. 3.1.1.2. For IBD and PTRD: To the nearest point of another ship or a
barge.

C9.6.2.3.1.2. Measurement of separation distances between ships or barges and

shore ES shall be from the nearest point of a ship’s magazine or the barge to the nearest point of
the ES.

C9.6.2.3.2. Pier Operations. Measurement of separation distances from piers to

surrounding facilities shall be from the nearest point that AE will be handled to the nearest point
of an ES. (NOTE: Movement of railcars or trucks passing through the clear space between ships
at a pier or between piers is considered as an operational risk. It is generally impracticable to
separate berths at a single pier by enough distance to prevent mass detonation of HD 1.1. To the
extent operationally feasible, the number of such exposures and total time required should be
reduced to the maximum extent practicable through scheduling.)

C9.6.2.3.3. Anchorages. Measurements from anchorages generally shall be from the

boundary of the area designated for the explosives anchorage. The explosives anchorage for a
single ship is a circle, the radius of which is the distance from the mooring buoy or a ship’s
anchor to the stern of the ship or of the AE lighters alongside when riding to the full scope of the
chain. For an explosives anchorage, the separation distance to an ES will depend upon whether
any ships are separated properly (see subparagraph C9.6.2.2.2.).

C9.6.3. Siting Criteria and Application of QD

C9.6.3.1. Maritime Prepositioning Ships (MPS)

174 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.3.1.1. Reduced QD criteria may be applied to those MPS that contain up to

1,300,000 lbs [589,667 kg] NEWQD of AE stored in standard International Standardization
Organization (ISO) shipping containers.

C9.6.3.1.2. IBD and PTRD for MPS can be determined using K = 40.85 [16.21] with
a 3,700-ft [1,128 m] minimum fragment distance for IBD and K = 24.01 [9.52] with a 2,220-ft
[677 m] minimum fragment distance for PTRD for MPS loads where no more than 52 percent of
the NEWQD is HD 1.1. When the percentage of HD 1.1 is:

C9.6.3.1.2.1. Between 52 and 65 percent, use the IBD and PTRD columns of
Table C9.T28.

C9.6.3.1.2.2. Above 65 percent, use the Other PES columns of Table C9.T1. with
a 3,700-ft [1,128 m] minimum fragment distance for IBD and a 2,220-ft [677 m] minimum
fragment distance for PTRD.

C9.6.3.1.3. The QD between applicable MPS piers/anchorages and non-explosives

loading piers/anchorages can be determined using K = 32 [12.69] with a 3,500 ft [1,067 m]
minimum fragment distance for MPS loads, where no more than 52 percent of the total NEWQD
is HD 1.1. (An exception for non-explosives MPS is provided in subparagraph C9.6.3.8.1.)
When the percentage of HD 1.1 is:

C9.6.3.1.3.1. Between 52 and 65 percent, use the Ship-to-Ship column in Table

C9.T28.

C9.6.3.1.3.2. Above 65 percent, use K = 40 [15.87] with a minimum fragment

distance of 3,500 ft [1,067 m].

2. With a minimum fragment distance of 2,220 ft [677m].
3. With a minimum fragment distance of 3,500 ft [1,067m].

C9.6.3.2. Scuttling Site. A properly located scuttling site will, when feasible, be
provided for positioning a ship for its flooding or sinking in the event it catches fire and must be
moved to avert damage to other ships or piers. The location of a scuttling site shall depend on
the greatest NEWQD that may be in a single ship at any one time. (Table C9.T1. provides the
applicable QD.) Additional considerations for the scuttling site include:

C9.6.3.2.1. The site should have sufficient maneuvering room and depth to permit
sinking the largest vessel that may be handled at the installation so that the holds will be flooded
completely at low tide.

C9.6.3.2.2. The scuttling site should provide the best available protection to other
ships, piers, and shore installations in the event of a mass explosion.

176 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.3.3. Explosives Anchorage. Explosives anchorage shall be separated from the main
ship channel and from normally traversed routes of ships entering or leaving the harbor by the
distances indicated below. (Occasional watercraft passing through the arcs, while outside both
the main ship channel and normally traversed routes of ships entering and leaving the harbor, are
not subject to QD requirements.)

C9.6.3.3.1. The PTRD from “Other PES” column of Table C9.T1. and

C9.6.3.3.2. The turning circles and stopping distances of other ships passing the
anchorage but not less than 3,000 ft [914.4 m].

C9.6.3.3.3. Separation of Ships at Explosives Anchorages. When explosives

anchorages are used for both loading and unloading ships and for mooring loaded ships, they
shall be separated as follows:

C9.6.3.3.3.1. Loaded ships shall be separated one from another by 18W1/3

[7.14Q1/3].

C9.6.3.3.3.2. Loading and unloading ships shall be separated one from another by
11W1/3 [4.36Q1/3] and, when possible, by 18W1/3 [7.14Q1/3].

C9.6.3.3.3.3. Loaded ships shall be separated from ships loading and unloading
1/3
by 40W [15.87Q1/3].

C9.6.3.3.4. Separation of Explosives Anchorages from Explosives Piers. Explosives

anchorages shall be separated from explosives piers by 40W1/3 [15.87Q1/3], except when the
anchorage is used only for the loading or unloading of ships. In that case, 18W1/3 [7.14Q1/3] may
be used.

C9.6.3.4. Separation Distances of Ships at the Same Pier

C9.6.3.4.1. Berthing of two ships in tandem helps decrease the fragment hazard to
the AE cargo of the second ship because of the additional protection afforded by the bow or
stern.

C9.6.3.4.2. When two ships, which cannot be separated by 11W1/3 [4.36Q1/3], are
being loaded through all hatches at the same time, the spotting of railcars or trucks and the
loading of hatches in both ships should be planned in a manner that puts the greatest possible
distance both between the open hatches, and the trucks and railcars serving the two ships. When
possible, the loading of the ships shall be staggered.

C9.6.3.5. Separation of Wharf Yard from the Pier. A wharf yard shall be separated from
the pier, which it serves by 11W1/3 [4.36Q1/3] to prevent propagation. If this separation distance
cannot be met, then the wharf yard shall be considered as part of the ship or barge and added to it
for computation of the total amount of explosives for QD purposes.

177 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.6.3.6. Separation of Explosives Ships from Other Ships. Explosives ships being
loaded or unloaded shall be separated from non-explosives carrying ships and from loaded
explosives ships that are not underway by 40W1/3 [15.87Q1/3] distances. The PTRD from “Other
PES” column of Table C9.T1. shall be used for protection of ships that are underway.

C9.6.3.7. Barge Piers. Piers and wharfs used exclusively for loading or unloading AE on
barges or utility craft may be sited from other shore facilities as loading docks, IAW paragraph
C9.8.8. Shore facilities shall be sited under the same criteria as pier and wharf facilities, in
relation to barge piers.

C9.6.3.8. Separation of Preposition Program Ships at Anchorages. The Military Sealift

Command’s Prepositioning Program (i.e. Combat Prepositioning Force, Maritime Prepositioning
Force, Logistics Prepositioning Ships) operates both explosives-loaded and non-explosives
carrying ships that are then deployed to key locations around the world. These ships are pre-
loaded with military equipment and supplies necessary to support military forces on a short-
notice basis and thus support a common mission. The following criteria apply to Prepositioning
Program ships at anchorage:

C9.6.3.8.1. Non-explosives carrying ships shall be separated from explosives-loaded

ships by a minimum of 18W1/3 [7.14Q1/3].

C9.6.3.8.2. Non-explosives carrying ships shall be separated from non-

Prepositioning Program explosives-loaded ships by 40W1/3 [15.87Q1/3].

C9.6.3.8.3. Non-explosives carrying ships not associated with the Prepositioning

Program shall be separated from all explosives carrying ships by 40W1/3 [15.87Q1/3].

C9.6.3.8.4. All non-explosives carrying ships shall be separated from explosives

ships being loaded or unloaded by 40W1/3 [15.87Q1/3].

C9.6.4. QD Tables

C9.6.4.1. Figure C9.F10. illustrates required hazard factors. Table C9.T7B. provides the
corresponding separation distances.

C9.6.4.2. Table C9.T1. separation distances shall be maintained between explosives pier
and wharf facilities and other ES (e.g., administration and industrial areas, terminal boundaries,
main ship channels, and PTRD).

C9.6.4.3. As an ES, ships must be separated from AE operating and storage facilities
(including holding yards) by the “Other PES IBD” column of Table C9.T1.

C9.6.4.4. As a PES, ships must be separated from AE operating facilities by either the
barricaded IMD (K6 [2.38]) or unbarricaded IMD (K11 [4.36]) of Table C9.T5., as applicable.
An exception (see subparagraph C9.4.1.1.2.1.10.) is permitted when the ES is a container

178 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

stuffing and unstuffing operation that routinely supports AE ship loading and unloading
operations. (QD requirements of subparagraph C9.6.4.3. shall apply from such container
stuffing and unstuffing operations (as a PES) to an AE ship (as an ES).)

C9.6.5. General Cargo and Vehicles at AE Terminals

C9.6.5.1. Concurrent movements of mission-related general cargo, vehicles, and AE

through a terminal may be conducted for the purpose of loading or unloading the same ship.

C9.6.5.2. Concurrent operations involving other ships shall be conducted at applicable

QD separations. (See Figure C9.F10.)

C9.6.5.3. Separation of inert materials and equipment in holding areas shall be consistent
with paragraph C9.8.5.

C9.6.5.3.1. Personnel entering inert holding areas that are located within ESQD shall
be limited both in number and time of exposure.

C9.6.5.3.2. Any labor intense activity shall take place at IBD or PTRD, as applicable.

DoD 6055.09-STD, February 29, 2008

C9.7. UNDERGROUND STORAGE OF AE

C9.7.1. General

C9.7.1.1. This section provides QD standards for underground storage (e.g., natural
caverns and below grade, excavated chambers) and storage facilities providing the overpressure
confinement effects typically encountered in underground storage.

C9.7.1.2. These criteria are only applicable when the minimum distance from the
perimeter of a storage chamber to an exterior surface exceeds 0.25W1/3 [0.10Q 1/3]. (This
minimum distance normally, but not always, equals the thickness of the earth cover.)

C9.7.1.3. Use aboveground siting criteria when minimum distance criteria of

subparagraph C9.7.1.2. cannot be met.

C9.7.1.4. This section addresses explosives safety criteria both with and without rupture
of the earth cover.

C9.7.1.5. QD siting requirements of this section may be determined from the applicable
equations or by interpolating between the table and figure entries.

C9.7.1.6. Expected ground shock, debris, and airblast hazards from an accidental
explosion in an underground storage facility depend on several variables, including the local
geology and site-specific parameters. These parameters vary significantly from facility to
facility. Siting distances other than those listed may be used when validated by approved
experimental or analytical results showing equivalent protection to that required.

C9.7.2. External QD Determinations

C9.7.2.1. QD Dependence on HD. (See section C9.2. to determine the explosive weight
for mixed HD.)

C9.7.2.1.1. HD 1.1. Distances shall be determined from the total quantity of HD 1.1
in the individual chambers, unless the total quantity is subdivided to prevent rapid
communication of an incident from one subdivision to another. Connected chambers containing
HD 1.1 shall be treated as a single chamber site, unless explosion communication is prevented by
adequate subdivision or chamber separation.

C9.7.2.1.2. HD 1.2. Except for primary fragments from openings to underground

storage, external explosives safety hazards are not normally significant for HD 1.2. The safe
distance for both IBD and PTR is the IBD distance in Tables C9.T8. through C9.T12. for
locations within 10 degrees to either side of the centerline of a tunnel opening. These criteria
apply only to those detonations that occur where a line-of-sight path exists from the detonation
point to any portion of the tunnel opening. For detonations that do not have a line-of-sight path
to the tunnel opening, or where the line-of-sight path is intercepted by a barricade beyond the
opening, the IBD and PTR hazard distances are zero.

181 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.7.2.1.3. HD 1.3. HD 1.3 shall be treated as HD 1.1 with an explosive equivalence

of 100 percent for QD purposes. Any significant and validated differences in energy release per
unit mass of HD 1.3 from that of TNT may be considered.

C9.7.2.1.4. HD 1.4. External explosives safety hazards are not normally significant
for HD 1.4. Accordingly, external QD criteria do not apply for HD 1.4.

C9.7.2.1.5. HD 1.5. HD 1.5 shall be treated as HD 1.1 with an explosive equivalence

of 100 percent for QD purposes.

C9.7.2.1.6. HD 1.6. HD 1.6 shall be treated as HD 1.2.

C9.7.2.2. QD Reference Points

C9.7.2.2.1. Distances determined by blast or debris exiting from tunnel openings is

the minimum distance measured from the openings to the nearest wall or point of the location to
be protected. Use extended centerlines of the openings as reference lines for directional effects.

C9.7.2.2.2. Distances determined for airblast and debris produced by breaching of

the chamber cover shall be the minimum distance from an exterior point defined by chamber
cover thickness, on the ground surface above the storage chamber to the nearest wall or point of
the location to be protected. For configurations where the storage chambers are not distinct from
the access tunnel, the distance is the shortest distance from the tunnel roof directly above the
charge to the surface.

C9.7.2.2.3. Distances determined for ground shock shall be the minimum distance
measured from the nearest wall of the storage chamber to the location to be protected.

C9.7.2.3. IBD. IBD for HD 1.1 shall be the largest of those distances required for
protection against ground shock, debris, and airblast as defined below.

C9.7.2.3.1. Ground Shock

C9.7.2.3.1.1. For protection of residential buildings against significant structural

damage by ground shock, the maximum particle velocity induced in the ground at the building
site shall not exceed:

C9.7.2.3.1.1.1. 2.4 ips [6.1 cm/s] in soil.

C9.7.2.3.1.1.2. 4.5 ips [11.4 cm/s] in weak rock.

C9.7.2.3.1.1.3. 9.0 ips [22.9 cm/s] in strong rock.

182 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.7.2.3.1.2. The above values form the basis for the following equations
(NOTE: Dig is in ft and W is the explosive quantity in lb [Dig is in m and Q is the explosive
quantity in kg].):

C9.7.2.3.1.2.1. For sitings in moderately strong to strong rock with chamber

loading densities [NEWQD/chamber internal volume] of 3.0 lb/ft3 [48.1 kg/m3] or less, the IBD
for ground shock, Dig is:

Dig = 5.8W1/3 [English EQN C9.7-1]

Dig = 2.30Q1/3 [Metric EQN C9.7-2]

C9.7.2.3.1.2.2. For higher loading densities in chambers sited in moderately

strong to strong rock, and for all loading densities in other materials, the IBD for ground shock
(See C9.7.2.3.1.2.3. for values of decoupling factor, fg.) is:

Dig = 12.5fgW4/9 (Moderately strong to strong rock) [English EQN C9.7-3]

Dig = 5.41fgQ4/9 (Moderately strong to strong rock) [Metric EQN C9.7-4]
Dig = 11.1fgW4/9 (Weak rock) [English EQN C9.7-5]
Dig = 4.81fgQ4/9 (Weak rock) [Metric EQN C9.7-6]
Dig = 2.1fgW4/9 (Soil) [English EQN C9.7-7]
Dig = 0.91fgQ4/9 (Soil) [Metric EQN C9.7-8]

C9.7.2.3.1.2.3. The dimensionless, decoupling factor, fg, depends on chamber

loading density, w (lb/ft3 [kg/m3]), and is (Values of Dig and Dig/fg are given in Table C9.T29.
Values of fg are shown in Table C9.T30. Alternate values for Dig may be used only when
justified by site-specific ground shock data.):

fg = 0.267w0.3 [English EQN C9.7-9]

fg = 0.11604w0.3 [Metric EQN C9.7-10]

C9.7.2.3.2. Debris. (See paragraph C5.2.3. for special design considerations.)

C9.7.2.3.2.1. A minimum IBD distance of 1,800 ft [548.6 m] for debris throw

from an opening shall apply within 10 degrees to either side of the centerline axis of that
opening, unless positive means are used to prevent or control the debris throw.

C9.7.2.3.2.2. The distance Did that is required for protection of inhabited areas
against the effects of debris thrown from breaching of the cover material over a detonation
depends on the thickness of the cover (C) over the storage chamber. The critical cover thickness,
Cc , is defined as 2.5W1/3 [1.0Q1/3].

C9.7.2.3.2.2.1. When Cc > 2.5W1/3 [1.0Q1/3], debris from a surface breach

need not be considered.

C9.7.2.3.2.2.2. When Cc < 2.5W1/3 [1.0Q1/3], then the debris distance, Did
shall be calculated using the equation:

183 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

Did = fd*fc*W0.41 [English EQN C9.7-11]

Did = fd*fc*Q0.41 [Metric EQN C9.7-12]

C9.7.2.3.2.2.3. The dimensionless, decoupling factor, fd depends on chamber

loading density, w (lb/ft3 [kg/m3]), and is:
fd = 0.6w0.18 [English EQN C9.7-13]
fd = 0.3615 w0.18 [Metric EQN C9.7-14]

C9.7.2.3.2.2.4. Values of fd are shown in Table C9.T30. The coupling factor

fc is related to the type of rock around the storage chamber and the scaled cover thickness, C.
Values of fc are given in Table C9.T31.

C9.7.2.3.3. Airblast. (See paragraph C5.2.3. for special design considerations.)

C9.7.2.3.3.1. An explosion in an underground storage chamber may produce

external airblast from two sources; the exit of blast from existing openings (tunnel entrances,
ventilation shafts, etc.) and the rupture or breach of the chamber cover by the detonation.
Required IBD is independently determined for each of these airblast sources, with the maximum
IBD used for siting. If the chamber cover thickness is less than Cc given in subparagraph
C9.7.2.3.2., some external airblast will be produced depending on the cover thickness. Use the
following to determine IBD for airblast produced by breaching of the chamber cover:

C9.7.2.3.3.1.1. C < 0.25W1/3 ft [0.10Q1/3 m]: Use IBD for surface burst of
bare explosives charge (Table C9.T1., Note 4).

C9.7.2.3.3.1.2. 0.25W1/3 < C < 0.50W1/3 ft [0.10Q1/3 < C < 0.20Q1/3 m]: Use
1/2 of IBD for surface burst of bare explosives charge.

C9.7.2.3.3.1.3. 0.50W1/3 < C < 0.75W1/3 ft [0.20Q1/3 < C < 0.30Q1/3 m]: Use
1/4 of IBD for surface burst of bare explosives charge.

C9.7.2.3.3.1.4. 0.75W1/3 ft [0.30*Q1/3 m] < C: Airblast hazards from blast

through the earth cover are negligible relative to ground shock or debris hazards.

C9.7.2.3.3.2. Overpressure and debris hazards must be determined for each

facility opening whose cross-section area is five percent or more of that of the largest opening.

C9.7.2.3.3.2.1. Distance versus overpressure along the centerline axis of a

single opening is:
R = 149.3*DHYD*((W/VE)0.5/pSO)1/1.4 [English EQN C9.7-15]
R = 220.191*DHYD*((W/VE)0.5/pSO)1/1.4 [Metric EQN C9.7-16]
where:
R: Distance from opening (ft) [m],
DHYD: Effective hydraulic diameter that controls dynamic flow issuing from the
opening (feet) [m] (Compute D, using the minimum, cross-sectional area
of the tunnel that is located within five tunnel diameters of the opening, as
D = 4A/P, where A is the area and P is the perimeter.),
PSO: Overpressure at distance R (psi) [kPa],
W: MCE in lb [kg],
VE: Total volume engulfed by the blast wavefront within the tunnel system at
the time the wavefront arrives at the point of interest (ft3) [m3].

C9.7.2.3.3.2.2. Distance versus overpressure off the centerline axis of the

opening is:
R(T) = R(T=0)/(1 + (T/56)2)1/1.4 [English EQN C9.7-17]
where:
R(T =0) Distance along the centerline axis, and T is the horizontal angle from
the centerline (degrees).

C9.7.2.3.3.3. Equations [English EQN C9.7-15] [Metric EQN C9.7-16], and

[English EQN C9.7-17] show that the distance providing protection from an overpressure
exceeding PSO depends on the DHYD, and the angle from the centerline axis for the location of
interest. Table C9.T32. gives the ratio of off-axis to on-axis distances.

188 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.7.2.3.3.4. Find required IBD distances for airblast using the appropriate
equations discussed above, with the criteria that the total incident overpressure at IBD shall not
exceed:

PSO = 1.2 psi for W < 100,000 lbs,

PSO = 8.27 kPa for W < 45,359 kg,
PSO = 44.57*W-0.314 psi for 100,000 < W < 250,000 lbs [English EQN C9.7-18]
PSO = 239.753*W-0.314 kPa for 45,359 < W < 113,397.5 kg. [Metric EQN C9.7-19]
PSO = 0.9 psi for W > 250,000 lbs.
PSO = 6.21 kPa for W > 113,397.5 kg.

C9.7.2.3.3.5. For the overpressures of subparagraph C9.7.2.3.3.4, on-axis IBD

distances are:

R = 131.1*DHYD*(W/VE)1/2.8 for W < 100,000 lbs, [English EQN C9.7-20]

R = 48.683*DHYD*(W/VE)1/2.8 for W < 45,359 kg, [Metric EQN C9.7-21]
R = 9.91*DHYD*W0.581/VE0.357 for 100,000 <W < 250,000 lbs,
---- [English EQN C9.7-22]
R = 4.395*DHYD*W0.581/VE0.357 for 45,3599 < W < 113,397.5 kg,
---- [Metric EQN C9.7-23]
R = 161.0*DHYD*(W/VE)1/2.8 for W > 250,000 lbs [English EQN C9.7-24]
R = 59.787*DHYD*(W/VE)1/2.8 for W > 113,397.5 kg. [Metric EQN C9.7-25]

C9.7.2.3.3.6. QD distances for IBD for airblast may be determined from the
equations listed above or from entries in Tables C9.T33. and C9.T34.

C9.7.2.4. PTRD. PTRD for HD 1.1 is 60 percent of IBD for ground shock, debris, or
airblast, whichever is greater.

C9.7.2.5. ILD. ILD for HD 1.1 is the greater of the following:

C9.7.2.5.1. Ground Shock. Does not apply.

C9.7.2.5.2. Debris. For locations within 10 degrees of either side of the centerline of
a tunnel opening, site intraline facilities at IBD (see subparagraph C9.7.2.3.). QD criteria for
debris are not applicable to locations outside 10 degrees of either side of the centerline axis of an
opening.

C9.7.2.5.3. Airblast. Overpressure at barricaded and unbarricaded intraline distances

shall not exceed 12 psi [82.7 kPa] and 3.5 psi [24.1 kPa], respectively.

pSO = 6.21 kPa W > 113,397.5 kg
2. For IBD reductions with mitigating devices, see C5.2.3.3.

C9.8. FACILITIES SITING CRITERIA

This section establishes criteria for siting AE and non-AE facilities with respect to PES.

C9.8.1. Administration and Industrial Areas and Auxiliary Facilities

C9.8.1.1. Administration and industrial areas shall be separated from a PES by IBD.

C9.8.1.2. Auxiliary facilities (e.g., heating plants, line offices, break areas, briefing
rooms for daily work schedules or site safety matters, joiner shops, security posts, and similar
functions) located at or near AE operations and servicing only one building or operation may be
located at fire protection distance (50 ft [15.2 m] for non-combustible structures, 100 ft [30.5 m]
for combustible structures) from the building or operation they support.

C9.8.2. Classification Yard

C9.8.2.1. For protection of the classification yard from a PES, separation distances shall
be at least the applicable IMD.

C9.8.2.2. Specific QD separation is not required from the classification yard to ES when
the classification yard is used exclusively for:

C9.8.2.2.1. Receiving, dispatching, classifying, and switching of cars.

C9.8.2.2.2. Interchanging of trucks, trailers, or railcars between the common carrier

and the DoD activity.

C9.8.2.2.3. Conducting external inspection of motor vehicles or railcars, or opening

of free-rolling doors of railcars for the purpose of removing documents and making a visual
inspection of the cargo.

C9.8.2.3. Specific QD separation applies if the classification yard is used for any other
purpose.

194 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.3. Areas for Burning AE. Use the QD formula described in subparagraph C2.2.1.3.
and the requirements in subparagraphs C9.8.3.1. through C9.8.3.3. to determine safe locations
for burning AE.

C9.8.3.1. Use K24 [9.52] in the QD formula to determine the minimum safe distance for
either personnel burning AE or those conducting unrelated AE operations.

C9.8.3.2. Use K40 [15.87] in the QD formula to determine the safe distance for persons
not performing AE operations. However, if the NEWQD of burn material is more than 450 lbs
[204 kg], the minimum safe distance shall be at least 1,250 ft [381 m]. If the NEWQD of burn
material is < 450 lbs [204 kg], use the minimum HFD given in Table C9.T2.

C9.8.3.3. Locate burning grounds at ILD from other PES.

C9.8.4. Areas Used for Intentional Detonations

C9.8.4.1. General

C9.8.4.1.1. Protective structures for personnel or measures to suppress blast or

fragment effects may be used to reduce the required withdrawal distances.

C9.8.4.1.2. Control sites for intentional detonations for AE disposals, live-fire

demonstrations, and Explosive Ordnance Disposal (EOD) non-emergency operations must be at
ILD from other PES, based on the PES’s NEWQD.

C9.8.4.2. The minimum separation distances between areas used for intentional
detonation (excluding hands-on training) and nonessential personnel are determined by
application of the criteria given below. If the minimum separation distance requirements for
previously approved DDESB sitings or those prescribed in this section cannot be met, then
personnel shall be provided the protection specified in paragraph C4.3.2.

C9.8.4.2.1. For non-fragmenting AE, use d = 328W1/3 but not less than 1,250 ft [d =
1/3
130.1Q , but not less than 381 m]. If known, maximum debris throw distance, with a safety
factor determined by the DoD Component, may be used to replace the 1,250 ft [381 m] minimum
distance.

C9.8.4.2.2. For fragmenting AE use the larger of the two distances below:

C9.8.4.2.2.1. The distance determined from the equation d = 328W1/3 but not less
than 1,250 ft [d = 130.1Q1/3 but not less than 381 m].

C9.8.4.2.2.2. The distances given in Table C9.T35., based on the diameter of the
AE being destroyed. A calculated or measured maximum fragment throw distance (including the
interaction effects for stacks of items or single items, whichever applies), with a safety factor
determined by the DoD Component, may be used to replace these distances. Calculated case
fragment maximum throw distances for selected munitions are given in Table C9.T36. (The

195 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

calculated case fragment throw distances in Tables C9.T35. and C9.T36. are for individual items.
These throw distances do not consider “rogue” fragments that are produced by sections of nose
plugs, base plates, or lugs, and they do not directly apply to stacks of munitions. In addition,
shaped charge jets or slugs from directed energy munitions can travel significantly greater
distances than case fragments; therefore, these munitions require specific analysis.)

C9.8.4.2.2.2.1. “Rogue” fragments can travel significantly greater distances

(> 10,000 ft [3,048 m]) than those shown in Tables C9.T35. and C9.T36. Care must be taken
either to properly orient the munition (e.g., lugs or strongbacks and nose or tail plate sections
oriented away from personnel locations), or to minimize or eliminate the hazard of rogue
fragments (e.g., sandbagging the munition prior to detonation).

C9.8.4.2.2.2.2. For multiple munitions’ detonation, the preferred approach is:

C9.8.4.2.2.2.2.1. Place the munitions in a single layer with their sides

touching such that their axis is horizontal.

C9.8.4.2.2.2.2.2. Place the munitions so that the nose of each munition is

pointing in the same direction.

C9.8.4.2.2.2.2.3. Orient the munitions so that lugs or strongbacks and

nose or tail plate sections are facing away from areas to be protected.

C9.8.4.2.2.2.2.4. Initiate the stack detonation so that all munitions

detonate simultaneously.

C9.8.4.2.2.2.2.5. Use the following when the procedures outlined in

subparagraphs C9.8.4.2.2.2.2.1. through C9.8.4.2.2.2.2.4. cannot be met:

C9.8.4.2.2.2.2.5.1. If the orientation of the potential rogue fragments

can be controlled, then the ranges given in Tables C9.T35. and C9.T36. shall be increased by 20
percent to account for the interaction effects.

C9.8.4.2.2.2.2.5.2. If the orientation of potential rogue fragments

cannot be controlled, fragment ranges must be evaluated on a case-by-case basis.

C9.8.4.2.2.2.2.5.3. If detonations involve stacks of mixed munitions,

evaluate the distance for each munition separately using the procedures in subparagraph
C9.8.4.2.2.2. and select the largest distance.

Notes for Table C9.T36.:

1. These calculated case fragment throw distances are for individual items and do not apply to detonations
involving multiple munitions. See subparagraph C9.8.4.2.2.2. for application to detonation of multiple munitions.
In addition, shaped charge jets or slugs from directed energy munitions can travel significantly greater distances than
case fragments; therefore, these munitions require specific analysis.
2. These calculated fragment throw distances are for individual munitions and do not apply to stacks. They also
do not address “rogue” (non-case) fragments that can be produced from sections of nose plugs, base plates, or lugs.
Rogue fragments can travel to significantly greater distances (i.e., > 10,000 ft [3,048 m]) than those shown. Care
must be taken to properly orient the munition or take other measures to minimize rogue fragment hazards.

C9.8.4.3. EOD Operations

C9.8.4.3.1. EOD operational responses require the application of public withdrawal

distances to all nonessential personnel per Table C8.T4.

C9.8.4.3.2. EOD operations or demonstrations conducted on ranges require

minimum separation distances (see subparagraph C9.8.4.2.) for nonessential personnel.

C9.8.4.3.3. EOD training operations, or operations involving demolition of AE, do

not require minimum separation distances for essential personnel. The onsite DoD authority
shall determine adequate protection for essential personnel.

200 CHAPTER 9

C9.8.4.3.4. EOD Proficiency Training Ranges. EOD proficiency-training ranges are

limited to a maximum of 5 lbs [2.27 kg] of demolition explosives (e.g., bare charges or items
without a fragment hazard).

C9.8.4.3.4.1. Facilities that require IBD, PTRD, and ILD protection must be
located at the following minimum distances from the destruction point:

C9.8.4.3.4.1.1. If the destruction point is at least 500 ft [152.4 m] from these

facilities, a 5-lb [2.27 kg] NEWQD limit applies.

C9.8.4.3.4.1.2. If the destruction point is less than 500 ft [152.4 m], but 300 ft
[91.4 m] or more from these facilities, a 2.5-lb [1.13 kg] NEWQD limit applies.

C9.8.4.3.4.1.3. If the destruction point is less than 300 ft [91.4 m], but 200 ft
[61 m] or more from these facilities, a 1.25-lb [0.57 kg] NEWQD limit applies.

C9.8.4.3.4.2. Barricading of Destruction Point. If the EOD Proficiency Training

Range provides the 500-foot protection distance specified in subparagraph C9.8.4.3.4.1.1., then
no barricading of the destruction point is required. If the EOD Proficiency Training Range
provides less than 500 feet protection distance, then the range’s destruction point shall be
constructed to control ejection of debris by:

C9.8.4.3.4.2.1. Constructing a barricade with two entrances, which surrounds

the destruction point, that is the equivalent of at least two side-to-side sandbags, is at least 6 ft
[1.83 m] high, and is constructed within about 10 ft [3.05 m] of the destruction point.

C9.8.4.3.4.2.2. Locating the barricade entrances at 180 degrees separation.

These entrances shall be barricaded, as above, to effectively block all debris.

C9.8.4.3.4.3. EOD proficiency training ranges used with other than bare charges
or non-fragment producing items shall meet the requirements of subparagraph C9.8.4.1.

C9.8.4.3.4.4. EOD proficiency training ranges on which explosively operated

tool kits are used on inert AE only require 100 ft [30.5 m] separation distance between the
destruction point and facilities that require IBD, PTRD, and ILD protection. The site shall be
barricaded per subparagraph C9.8.4.3.4.2.

C9.8.4.4. Live-fire Demonstrations and Disposal Operations. The appropriate DoD

authority shall determine, on a case-by-case basis:

C9.8.4.4.1.1. Essential personnel required for the live-fire demonstrations or

disposal operations.

C9.8.4.4.1.2. Other range safety considerations (e.g., personnel withdrawal

distances and acceptable exposures).

201 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.5. Inert Storage. The DoD Components shall determine acceptable locations for inert
storage that is directly related to the explosives mission, and for inert storage that is not directly
related but where control of and access to such inert storage is restricted only to personnel
directly related to the explosives mission. The DoD Components shall determine what
constitutes “directly related.” The following apply to inert storage:

C9.8.5.1. Locations for inert storage shall be determined only after consideration of
personnel exposure, the importance of the materiel in relation to the explosives mission, the
operational conditions, and the availability of space.

C9.8.5.2. Site plans meeting the conditions above are not required to be submitted to the
DDESB for review and approval (see paragraph C5.5.9.).

C9.8.5.3. Inert storage that will be accessed by personnel not related to the explosives
mission shall be sited per subparagraphs C9.4.1.1.4.7. and C9.4.1.1.6.9. (based on blast only).
Minimum fragment distances do not apply (see subparagraph C9.4.1.2.1.3.4.).

C9.8.6. Interchange Yards

C9.8.6.1. Truck, trailer, or railcar interchange yards are not subject to QD requirements,
when used exclusively:

C9.8.6.1.1. For the interchange of vehicles or railcars containing AE between the

commercial carrier and DoD activities.

C9.8.6.1.2. To conduct external inspection of the trucks, trailers, or railcars

containing AE.

C9.8.6.1.3. To conduct visual inspection of the external condition of the cargo in

vehicles (e.g., trucks, trailers, and railcars) that passed the external inspection.

C9.8.6.2. Truck, trailer, or railcar interchange used, at any time, for any purpose other
than the above are subject to applicable Q-D tables. (See subparagraph C9.3.1.7.)

C9.8.7. Inter-DoD Component Support and Tactical Facilities

C9.8.7.1. General.

C9.8.7.1.1. The separation distances in subparagraph C9.8.7.2. shall apply between

facilities of one DoD Component to those of another DoD Component regardless of the location
of the boundaries.

C9.8.7.1.2. Other safety criteria (e.g., toxicity, noise, radiation, flight trajectory) may
require greater distances. In these situations, the predominant hazard criteria shall apply.

C9.8.7.2. The following minimum QD relationships apply:

202 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.7.2.1. AE storage facilities shall be separated by IMD.

C9.8.7.2.2. AE storage or operating locations of one DoD Component shall be

separated from AE operating locations of another DoD Component by IBD. (See subparagraph
C9.8.7.2.3. for an exception to this criterion.)

C9.8.7.2.3. Explosive operations that present a similar degree of hazard or involve

joint or support operations shall be separated by ILD.

C9.8.7.2.4. AE storage or operating locations of one DoD Component shall be

separated from AE tactical facilities of another DoD Component by IBD. For joint or support
operations, determine the separation distance as though both facilities belonged to a single DoD
Component.

C9.8.8. Detached Loading Docks. Detached loading docks that normally service multiple
facilities shall be sited on the basis of use.

C9.8.8.1. When servicing magazines, they must be separated from magazines by IMD.

C9.8.8.2. When servicing operating buildings, they must be separated from the operating
buildings by ILD.

C9.8.9. Holding Yards for Railcars and Trucks Containing AE

C9.8.9.1. Railcar groups containing AE shall be separated from each other by AGM
distance in a railcar holding yard. For example:

C9.8.9.1.1. If the railcar holding yard is formed by two parallel ladder tracks
connected by diagonal spurs, the parallel tracks and the diagonal spurs shall be separated by
AGM distance for the quantities of AE involved.

C9.8.9.1.2. If the railcar holding yard is a “Christmas tree” arrangement, consisting

of a ladder track with diagonal dead-end spurs projecting from each side at alternate intervals,
the spurs shall be separated by AGM distance for the quantities of AE involved.

C9.8.9.2. Truck groups containing AE in holding yards shall be separated from each
other by AGM distance.

C9.8.9.3. Both railcar and truck holding yards containing AE shall be separated from
other facilities by the applicable IBD, PTRD, ILD, or IMD.

C9.8.9.4. In addition to the temporary parking of railcars, trucks, or trailers containing

AE, holding yards may also be used to interchange truck, trailers, or railcars between the
commercial carrier and the DoD activity, and also to conduct visual inspections.

203 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.10. Inspection Stations for Railcars and Trucks Containing AE

C9.8.10.1. Inspection stations for railcars and trucks containing AE that are used
exclusively for the activities below are not subject to QD criteria. However, these stations
should be located as far as practical from other hazards or populated areas. Allowable activities
are:

C9.8.10.1.1. External visual inspection of the railcars or motor vehicles.

C9.8.10.1.2. Visual inspection of the external condition of the cargo packaging in

vehicles that have passed the external inspection indicated in subparagraph C9.8.10.1.1.

C9.8.10.1.3. Interchange of trucks, trailers, or railcars between the common carrier

and the DoD activity.

C9.8.10.2. Inspection stations used for any other purpose shall comply with applicable
QD criteria.

C9.8.11. Holding Areas for Suspect Railcars or Trucks Containing AE. Railcars or trucks
that are suspected of being in a hazardous condition shall be separated (isolated) from other PES
or ES by the applicable QD before any other action.

C9.8.12. AE Transportation Mode Change Locations. Movement and transfer of DoD-titled

AE must comply with national, international, and host country-specific transportation
regulations. QD criteria apply to all transfer operations involving DoD-titled AE.

C9.8.13. Secure Holding Area. An area designated for the temporary parking of commercial
carriers’ motor vehicles transporting DoD-owned Arms, Ammunition, and Explosives (AAE),
classified (SECRET or CONFIDENTIAL) materials, and Controlled Cryptographic Items (CCI).
There are two types of secure holding areas and the criteria for each are provided below.
(Although the intent of such areas is to provide a secure storage location for commercial carriers
while in transit, or during emergencies or other circumstances that are beyond a carrier’s control,
this Standard imposes no requirement for installations to have such areas. The term Secure
Holding Area is applicable to areas (CONUS, Hawaii, Alaska, and Puerto Rico) governed by
DoD 4500.9-R (Reference (aa)).)

C9.8.13.1. Secure Explosives Holding Area. Site as a holding yard per paragraph
C9.8.9.

C9.8.13.2. Secure Non-explosives Holding Area. No siting required if located outside

all QD arcs. If located within a QD arc, site as an administrative parking lot per subparagraph
C9.4.1.1.4.6. The holding of HD 1.4S materials, without regard to QD, is permitted at this
location.

C9.8.14. Storage Tanks for Hazardous Materials

204 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.14.1. Unprotected, aboveground bulk storage tanks shall be separated from PES by
IBD per Table C9.T1. A dike system satisfying Reference (s) is required. Aboveground storage
tanks that are provided protection against rupture or collapse from blast and fragment hazards
may be sited at distances less than Table C9.T1. when supported by testing or analysis.

C9.8.14.2. For installation of smaller bulk storage tanks, weigh the cost of distance or
protective construction against the strategic value of the stored material, the ease of replacement
in the event of an accident, and the potential environmental impact. Reduced distances may be
approved if:

C9.8.14.2.1. The losses are accepted by the DoD Component.

C9.8.14.2.2. The tanks are sited.

C9.8.14.2.3. Spill containment is provided so other exposures are not endangered.

C9.8.14.3. Unprotected service tanks solely supporting AE storage or operating

complexes that are supplied by a pipe system designed to resist blast and fragments may be sited
at IBD based on blast only with a minimum distance of 400 ft [121.9 m] if:

C9.8.14.3.1. A dike system meeting the requirements of Reference (s) is provided.

C9.8.14.3.2. The DoD Component accepts the possible loss of the tanks and any
collateral damage that a fire might cause as a result of the tanks being punctured by fragments.

C9.8.14.4. A service tank supporting a single PES shall be separated from that PES by
the applicable NFPA fire protection distance. The distance from this service tank to any other
PES shall be the larger of the required distance between the two PES or the applicable NFPA fire
protection distance.

C9.8.14.5. Buried tanks and buried pipelines should be separated from all PES
containing HD 1.2, HD 1.3, HD 1.4, or HD 1.6 AE by at least 80 ft [24.4 m]. The required
separation distance for HD 1.1 or HD 1.5 AE is K3 [1.19] with a minimum of 80 ft [24.4 m]. If
the PES is designed to contain the effects of an explosion, then no QD is required.

C9.8.14.6. Small quantities of POL or other hazardous materials used for operational
purposes require no specific separation distance for explosives safety; however, operating
procedures shall be implemented to limit adverse environmental impacts in the event of an
accidental explosion.

C9.8.14.7. For underground AE facilities, it is not practical to specify QD criteria that

cover all tank storage configurations. The DoD Component shall assess each configuration per
section C9.7 to ensure that equivalent protection of subparagraphs C9.8.14.1. through C9.8.14.6.
is provided.

C9.8.15. Storage Tanks for Water

205 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.15.1. Unprotected aboveground water storage tanks shall meet the siting
requirements of subparagraph C9.8.14.1. if loss of the tank is unacceptable to the DoD
Component. Buried tanks and associated components of like value shall meet the siting
requirements of subparagraph C9.8.14.5. Aboveground storage tanks that are provided
protection against rupture or collapse from blast and fragment hazards may be sited at distances
less than Table C9.T1. when supported by testing or analysis. No dike is required.

C9.8.15.2. QD criteria do not apply to water storage tanks and associated components if
loss is acceptable to the DoD Component.

C9.8.16. Underground Tanks or Pipelines for Non-Hazardous Materials. See subparagraph

C9.8.14.5.

C9.8.17. Temporary Construction or Maintenance Operations. Construction and

maintenance personnel who are temporarily near a PES to perform their job shall be provided the
maximum practicable protection from the effects of an explosion if one occurs at a PES. The
DoD Component shall determine the minimum practicable separation distance from PES for
such personnel and shall control operations at the PES to minimize personnel exposure to
hazards from an explosion. Documentation of the rationale for the control measures taken shall
be maintained until construction or maintenance operations are completed.

C9.8.18. Military Working Dog (MWD) Explosives Search Training. Training of MWD
involves searches to detect explosives that have been hidden in various public places. These
training operations typically include handling explosives, cutting or dividing explosive training
aids, removing explosives from shipping and storage containers, and repackaging explosives into
other containers. For these reasons, training operations shall:

C9.8.18.1. Be conducted by personnel meeting DoD Component qualifications.

C9.8.18.2. Be conducted in facilities that meet the requirements of this Standard.

C9.8.18.3. Store explosives in facilities that meet the requirements of this Standard.

C9.8.18.4. Provide non-essential personnel:

C9.8.18.4.1. 40W1/3 [15.87Q1/3] separation distance from the training site if more
than 15 lbs [6.8 kg] NEWQD are being used for the exercise.

C9.8.18.4.2. 100 ft [30.5 m] separation distance from the training site for NEWQD <
15 lbs [6.8 kg].

C9.8.18.5. Minimize the number of samples and the quantity of explosives for each
sample. The DoD Component shall determine the total quantity of explosives permitted during
an exercise considering:

206 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.18.5.1. The value and importance of the exposed facilities.

C9.8.18.5.2. The exercise operating conditions.

C9.8.18.5.3. The available separation distance for nonessential personnel.

C9.8.18.6. Separate samples a sufficient distance apart to prevent an explosion from

propagating from one sample to another.

C9.8.18.7. Not use any initiating devices or initiating explosives.

C9.8.18.8. Not place explosives near any heat or spark producing items (e.g., bare
electrical wiring, radiators, electric heaters, heating vents, etc.).

C9.8.18.9. Not place explosives in metal containers or other means of confinement that
could produce fragments in the event of an accidental explosion.

C9.8.19. Demilitarization Processing Equipment and Operations for Expended .50-Caliber

and Smaller Cartridge Casings

C9.8.19.1. A demilitarization operation for processing expended .50-caliber and smaller

cartridge cases can be treated as a non-explosive operation provided:

C9.8.19.1.1. Cartridge casings to be processed are screened prior to processing.

(Screening is intended to ensure that only .50-caliber and smaller are processed, and to remove
unused .50-caliber and smaller cartridges.)

C9.8.19.1.2. Demilitarization processing equipment is tested to be capable of

containing overpressure, fragment, and thermal hazards associated with a worst-case reaction
involving a single live round of the most energetic cartridge that could be processed in the
equipment.

C9.8.19.1.3. Demilitarization processing equipment is operated within the

manufacturer’s specifications and restricted only to the processing of expended .50-caliber and
smaller cartridge casings.

C9.8.19.1.4. Demilitarization processing equipment is inspected and maintained to

ensure safe operation.

C9.8.19.2. DoD Components shall:

C9.8.19.2.1. Approve the use of specific demilitarization processing equipment.

C9.8.19.2.2. Establish and implement procedures for:

C9.8.19.2.2.1. Screening and segregating the material to be processed.

207 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.19.2.2.2. Operating, inspecting, and maintaining the demilitarization

processing equipment to ensure safe operation.

C9.8.19.2.2.3. Dispositioning of processed material.

C9.8.19.3. Explosives Safety Siting

C9.8.19.3.1. Demilitarization processing operation locations meeting subparagraphs

C9.8.19.1. and C9.8.19.2., and located outside of IBD from all PES, do not require submission of
a site plan to the DDESB (see paragraph C5.5.10.).

C9.8.19.3.2. Locations used for demilitarization processing operations that are

located within IBD arcs:

C9.8.19.3.2.1. Require submission of a site plan to the DDESB.

C9.8.19.3.2.2. Shall be sited at ILD, except from the PES to which it is integral.

C9.8.20. Conveyance Loading and Unloading at a Magazine. A conveyance (e.g., truck,

trailer, railcar, ISO or Military Van (MILVAN) container) loading and unloading operation is
permitted at a magazine without regard to QD between the magazine and the operation. “At a
magazine” means loading and unloading operations at a loading dock attached to the magazine,
or on the pad/apron in front of the magazine, or within the established boundaries of an
aboveground magazine. Detached ramps or loading docks that normally service multiple
facilities will be sited in accordance with paragraph C9.8.8.

C9.8.21. Reduced QD Magazines. The below criteria address the use of DDESB-approved
reduced QD magazines (e.g., GOLAN 5, 10, and 15, NABCO SV-23 and SV-50, EOD
magazine, Advanced EOD Magazine, and other similar magazines listed in Table AP1-4. of
Reference (j)) for AE storage.

C9.8.21.1. Siting of Reduced QD Magazines

C9.8.21.1.1. Reduced QD magazines shall be sited as AGM, using the reduced QD

distances established as part of the DDESB approval package for each type of magazine.

C9.8.21.1.2. A DDESB-approved site plan is required prior to the use of a reduced

QD magazine for AE storage. However, when circumstances dictate, use of a magazine may
proceed before DDESB approval provided the Service-level explosives safety office (i.e.,
USATCES, NOSSA, MARCORSYSCOM PM AMMO, or AFSC) has reviewed and approved
the submission, the submission is at the DDESB for review and approval, and the DoD
Component accepts that the DDESB approval process may impose different or additional
requirements.

208 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.21.1.3. Siting of reduced QD magazines shall comply with specific provisions

for their use (e.g., venting, grounding) identified as part of the DDESB approval package for
each type of magazine.

C9.8.21.1.4. The QD distances approved by the DDESB for reduced QD magazines

do not account for the hazards presented to surrounding exposures when the magazine door is
open or when authorized AE operations are conducted at the magazine. The following criteria
are intended to minimize these hazards:

C9.8.21.1.4.1. The reduced QD magazine should be located and oriented to

maximize protection of surrounding exposures. The selection of a location for the reduced QD
magazine shall not be simply for convenience, but shall consider the direction of the door,
planned operations, and the need to minimize exposure of personnel and facilities.

C9.8.21.1.4.2. The reduced QD magazine door should be directed away from

occupied spaces and facilities, or at a minimum directed away from the highest exposures.

C9.8.21.1.4.3. For a reduced QD magazine authorized to contain up to 30 pounds

[13.60 kg] NEWQD of HD 1.1, a minimum 50-foot [15.24 m] separation distance should be
maintained from the door of the magazine, and from any authorized AE operation at the
magazine, to the nearest occupied space or facility. For a reduced QD magazine authorized to
contain 30 to 50 pounds [22.68 kg] NEWQD of HD 1.1, a minimum 100-foot [30.50 m]
separation distance should be maintained from the door of the magazine, and from any
authorized AE operation at the magazine, to the nearest occupied space or facility. At these
separation distances, only minor damage to exposed facilities is expected as a result of blast
overpressure; however, window breakage will likely occur and may present some risk to
personnel in exposed facilities. Fragmentation hazards are not addressed by these separation
distances. Barricades (see subparagraph C9.8.21.2.2.6.) may be used to stop low-angle, high-
velocity fragments, which present the greatest threat to surrounding exposures.

C9.8.21.2. Authorized Operations at Reduced QD Magazines. Significant personnel

exposure and risk reductions are obtained by the use of reduced QD magazines for AE storage,
even when short-duration explosives operations are conducted at such magazines. Therefore,
certain AE operations are authorized at a reduced QD magazine, without regard to QD. (NOTE:
AE operations not authorized below require siting as an operating location.)

C9.8.21.2.1. The following AE operations may be conducted at reduced QD

magazines without regard to QD, provided the requirements of subparagraph C9.8.21.2.2. are
met: (The below criteria and guidance modify the criteria and guidance for AE operations
identified as part of the DDESB approval package for each type of magazine.)

C9.8.21.2.1.1. The movement of packaged AE into and out of reduced QD

magazines.

209 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.21.2.1.2. The removal of internal packaged AE items from outer packaging

(e.g., removal of individually packaged dog scent kit samples from their larger shipping
container).

C9.8.21.2.1.3. The rotation and replacement of dynamite samples in dog scent

kits, as required to meet DoD criteria.

C9.8.21.2.1.4. The issuance of security or reaction force AE for installation force

protection, antiterrorism, or other similar mission.

C9.8.21.2.1.5. The removal and replacement of EOD materials contained in the

large pumice containers in the Advanced EOD Magazine. (This is because the pumice
containers are too large to transport in and out of the magazine.)

C9.8.21.2.1.6. The conduct of surveillance or inventory inspections that only

involve a visual serviceability inspection of AE.

C9.8.21.2.1.7. The placement of Munitions and Explosives of Concern (MEC)

that EOD personnel or Unexploded Ordnance (UXO)-qualified personnel have assessed and
determined acceptable for movement and storage in an appropriate reduced QD magazine
located at a Munitions Response Site (MRS).

C9.8.21.2.1.8. The conduct of other similar AE operations, provided:

C9.8.21.2.1.8.1. No direct energy is applied to the AE being handled (e.g.,

cutting, dividing, or crushing), except as allowed in subparagraph C9.8.21.2.1.9.

C9.8.21.2.1.8.2. The AE being handled have not been sensitized or made

more sensitive to initiation (e.g., primed).

C9.8.21.2.1.8.3. The AE being handled are not in a configuration that makes

them more susceptible to an unintentional detonation.

C9.8.21.2.1.9. The cutting of non-fragmenting AE (e.g., detonation cord, C4)

designed to be cut using authorized cutting tools, provided all nonessential personnel are
removed to a 40W1/3 [15.87Q1/3] separation distance with a 100 ft [30.5 m] minimum.

C9.8.21.2.2. The following requirements apply to authorized AE operations at

reduced QD magazines:

C9.8.21.2.2.1. The total NEWQD present (i.e., within the magazine and involved
in the operation) shall not exceed the rated NEWQD of the reduced QD magazine.

C9.8.21.2.2.2. To minimize the size and effects of an unintentional detonation,

operations conducted at reduced QD magazines shall be limited to the smallest MCE possible.

210 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.21.2.2.3. AE operations should not be conducted inside reduced QD

magazines unless absolutely necessary (as in the case of the Advanced EOD Magazine).
Conducting AE operations inside a magazine increases the MCE and the directional effects of an
internal explosion out the door.

C9.8.21.2.2.4. AE operations at reduced QD magazines should be conducted at

times when the exposure of unrelated personnel is at a minimum (i.e., at night; before or after
work shifts; on weekends).

C9.8.21.2.2.5. To take advantage of the barricade-type protection offered by the

reduced QD magazine structure, AE operations outside of reduced QD magazines shall be
conducted:

C9.8.21.2.2.5.1. As close to the base of the magazine as possible, with the

magazine door closed and secured (not required if the magazine does not contain AE).

C9.8.21.2.2.5.2. On the side of the magazine that is oriented away from the
surrounding area having the greatest exposure to be protected.

C9.8.21.2.2.6. Consideration should be given to constructing a barricade (to

defeat high-velocity, low-angle fragments) for AE operations at reduced QD magazines.
Acceptable barricading materials include sandbags and timber sand-filled walls; the barricade
shall not generate additional debris hazards. The barricade must be at least 6 feet [1.83 m] high,
provide line-of-sight protection between AE operations and exposures to be protected, and be the
equivalent of two side-by-side sandbags.

C9.8.22. Criteria for Non-DoD Explosives Activities (AE Operations and Storage) on DoD
Installations

C9.8.22.1. Non-DoD explosives activities shall only be conducted on DoD property per
Table C9.T37. These non-DoD explosives activities must also comply with Bureau of Alcohol,
Tobacco, and Firearms (BATF), Federal Aviation Administration (FAA), and other Federal,
State, and local regulations. Definitions for the terminology used in Table C9.T37. can be found
in the Glossary.

C9.8.22.2. For these types of non-DoD explosives activities, the Department of Defense
shall be responsible for ensuring that IMD requirements only, as outlined in explosives site plan
submissions, are met. DoD oversight of these non-DoD explosives activities is not intended.

C9.8.22.3. Non-DoD, explosives activities shall be evaluated based on IMD between

multiple PES to ensure non-propagation. Where IMD is not met, then the NEW at each site not
meeting IMD separation requirements shall be added together to determine the basis for the
applicable IMD or IBD to use for separation of DoD sites.

C9.8.22.4. In Table C9.T37., “Check for IMD” means if IMD is not maintained between
each PES, explosives quantities shall be totaled.

211 CHAPTER 9
DoD 6055.09-STD, February 29, 2008

C9.8.22.5. IBD shall be determined based on this Standard.

C9.8.22.6. The DoD site approval for non-DoD, explosives activities is limited to the
area encumbered by the IBD arcs.

C9.8.22.7. Review of building design, lightning protection, etc., is not necessary unless
design features are used as justification to reduce the IBD arc.

C10. CHAPTER 10
CONTINGENCIES, COMBAT OPERATIONS, MILITARY OPERATIONS OTHER THAN
WAR (MOOTW), AND ASSOCIATED TRAINING

C10.1. GENERAL

C10.1.1. This chapter provides the minimum criteria for contingencies, combat operations,
military operations other than war (MOOTW), and associated training. Full compliance with
other chapters of this Standard may not be possible during such operations. The DoD
Components may establish implementing regulations that are more protective than this Standard.
In situations involving combined or joint operations, the Commanders of the Combatant
Commands or the U.S. Commander of a Joint Task Force (JTF) shall designate the DoD
Component’s explosives safety criteria to be used.

C10.1.2. The provisions of this chapter only apply to:

C10.1.2.1. Those DoD AE activities located outside the United States.

C10.1.2.2. The Commanders of the Combatant Commands, the U.S. Commanders of

JTF, or the DoD Component Commanders in the management of these DoD AE activities.
When necessary, commanders may delegate certain explosive safety responsibilities to
designated subordinate commanders to ensure appropriate controls.

C10.1.2.3. Contingency, combat, and MOOTW training, regardless of location, when

specifically authorized by applicable DoD Component headquarters or Combatant Commander.
Prior to approval of this training, a risk analysis that thoroughly assesses asset preservation and
identifies the risk associated with the training shall be conducted. QD separations provided for
asset preservation shall be used for training, except where Chapter 9 permits lesser distances to
be used.

C10.1.3. This chapter provides optional criteria and risk management tools not available
elsewhere in this Standard. These optional criteria provide greater protection (asset preservation
distance) for assets deemed sufficiently critical to warrant the greater protection, and, in some
circumstances, provide lesser protection (minimum separation distance) for those assets for
which the mission requirements outweigh the increased risk to those assets.

C10.1.3.1. Asset Preservation Distance. At this distance from the PES, assets at the ES
are expected to be usable and mission capability is maintained following an incident. This
separation distance should prevent propagation between PES. (See subparagraphs C2.2.5.5. and
C2.2.5.6. for expected consequences for these separation distances.)

C10.1.3.2. Minimum Separation Distance. At this distance from the PES, mission
capability will likely be impaired or delayed. This separation distance should prevent prompt
propagation; however, late time propagation between PES is possible. (See subparagraphs
C2.2.5.2., C2.2.5.3., and C2.2.5.4. for expected consequences for these separation distances.)

DoD 6055.09-STD, February 29, 2008

C10.2. RISK MANAGEMENT

Consistent with operational requirements, it is DoD policy to manage risks associated with AE
(See section C1.2.). Exceptions to this chapter’s criteria are where equivalent protection is
provided or where a risk analysis is performed, as follows:

C10.2.1. Equivalent Protection. Analysis determining that protective construction or other

specialized safety features provides a level of protection equivalent to the separation distances
required by this Standard.

C10.2.2. Risk Analysis. Analysis determining that an acceptable level of safety is provided.
Risk analysis is a systematic procedure consisting of the following four steps:

C10.2.2.1. An event analysis to identify and describe possible events such as the
location, type of occurrence, probability of occurrence, and quantity of explosives.

C10.2.2.2. An effects analysis of the effects of the possible events to persons in the
surroundings such as blast pressure, fragmentation, and thermal hazards.

C10.2.2.3. An exposure analysis of the places, protection and time history of exposed
personnel in the hazardous areas.

C10.2.2.4. A risk calculation.

C10.2.3. Risk Management Control. The action a commander takes to minimize acceptable
risk. Such actions shall include:

C10.2.3.1. Development, implementation, and enforcement of applicable control

measures used to eliminate the hazard or reduce its risk.

C10.2.3.2. Continuous evaluation of the effectiveness of the implemented control

measures.

C10.3. SITE PLAN PROCESS

C10.3.1. Site Approval. All explosives locations falling within the scope of this Chapter
shall be approved by the applicable commander or by the DDESB as outlined below. Site plan
packages shall be submitted:

C10.3.1.1. For AE locations such as the following:

C10.3.1.1.1. Storage Locations.

213 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C10.3.1.1.2. Holding areas (e.g., Basic Load Ammunition Holding Areas (BLAHA),
flight line holding areas, port and railhead holding areas, and marshalling areas).

C10.3.1.1.3. Handling and operating locations (e.g., HAS, ports, AE maintenance,

repair, and renovation areas and sling-out areas).

C10.3.1.1.4. Forward Arming and Refueling Points (FARP).

C10.3.1.1.5. Combat Aircraft Parking Area (CAPA) and cargo aircraft parking areas.

C10.3.1.1.6. Static missile batteries.

C10.3.1.1.7. Locations used for the treatment or disposal (e.g., open burn or open
detonation) of munitions. Exceptions are those locations used in an emergency response, for
burning excess propellant resulting from munitions use during training, and those involved in
direct combat operations.

C10.3.1.2. Non-AE related ES within QD arcs.

C10.3.2. Documentation requirements. The operational situation and the type and duration
of the AE operations conducted at the site or facility determine the type of documentation
required for a site approval. The following categories of operations apply:

C10.3.2.1. Permanent.

C10.3.2.1.1. Definition. Those AE-related facilities where operations are expected to

continue for more than 12 months.

C10.3.2.1.2. Documentation Requirement. A DDESB-approved site plan for such

locations must be obtained once the Commander of the Combatant Commands or DoD
Component headquarters, as applicable, determines operations shall require the facilities’ use to
continue beyond 12 months.

C10.3.2.2 Recurrent

C10.3.2.2.1. Definition. Those AE-related facilities where operations are expected to

occur on a periodic basis regardless of the duration of the operation. These locations may be
sited using compensatory actions, such as facility evacuation or change-of-use, to minimize the
risks associated with AE operations.

C10.3.2.2.2. Documentation Requirement. These locations must have a DDESB-(or

appropriate level of command when applicable) approved site plan before commencing
operations.

C10.3.2.3. Temporary

214 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C10.3.2.3.1. Definition. Those AE-related facilities where operations are not

expected to continue for more than 12 months and are not recurrent, or for which advanced
planning and approval are impractical.

C10.3.2.3.2. Documentation Requirement. A plan for the specific scenario shall be

approved by the applicable commander. The plan shall include the following:

C10.3.2.3.2.1. A risk assessment for the proposed operation. This assessment

shall weigh the need for the facility against the potential effects of an accident (e.g., mission
impact, loss of resources, turnaround times).

C10.3.2.3.2.2. Schedule for the cessation of explosives operations or submittal of

a site plan if the operations exceed 12 months.

C10.3.2.4. Contingency, Combat, and MOOTW Training

C10.3.2.4.1. Definition. Those operations that simulate real world combat

environments using live AE to achieve training goals.

C10.3.2.4.2. Documentation Requirement. Facilities or areas for training activities

shall have a DDESB-approved site plan for permanent or recurrent operations, or a risk analysis
approved by the applicable commander for temporary operations.

C10.3.3. Site Plan Packages. See section C5.4. for the requirements with the following
additions:

C10.3.3.1. In the absence of suitable maps or drawings, information (e.g., sketches,

photographs, or other information) may be provided.

C10.3.3.2. An explanation of any deviations from pertinent safety standards caused by

local conditions.

C10.3.3.3. A copy of the risk analysis performed by the DoD Component, if one was
performed, to demonstrate equivalent protection.

C10.3.4. Approval Authority for Waivers and Exemptions. The Commander of the
Combatant Commands, the U.S. Commander of JTF, or the DoD Component Commander may,
for strategic and other compelling reasons, authorize waivers to the explosives safety standards
contained herein for the planning or conduct of contingencies, combat operations and MOOTW.
All waivers shall be coordinated with the host nation, as required, and consistent with
international agreements.

C10.3.4.1. Requests for waivers and exemptions to QD criteria shall be IAW DoD
Component directives. When joint operations are being conducted from a single base or
location, waivers and exemptions that affect another DoD Component must be coordinated
between affected DoD Components.

215 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C10.3.4.2. Requests for waivers and exemptions to QD criteria shall contain the
following:

C10.3.4.2.1. A risk analysis for the proposed operation weighing the need to conduct
the operation and violate the standards against the potential effect of an accident (e.g., mission
impact, loss of resources, turnaround times).

C10.3.4.2.2. A timeline listing milestones which shall eliminate the need for the
waiver or exemption.

C10.4. QD CRITERIA FOR CONTINGENCIES, COMBAT OPERATIONS, MOOTW

AND ASSOCIATED TRAINING

QD criteria are provided for specific types of locations below:

C10.4.1. BLAHA

C10.4.1.1. General. To fulfill their missions, certain units must keep their basic load
ammunition in armored vehicles, trucks, trailers, structures, or on pads. This involves
acceptance of greater risks to unit personnel, facilities, and equipment than permitted by other
chapters of this Standard. The concept of BLAHA storage may also be used to provide QD
separations during mobile operations. A Basic Load Storage Area (BLSA) is a location
containing multiple BLAHA.

C10.4.1.2. Mixing of Basic Load Ammunition. Storage compatibility requirements of

Chapter 3 do not apply to BLAHA facilities.

C10.4.1.2.1. NEWQD for use with BLAHA QD criteria shall be determined as

follows:

C10.4.1.2.1.1. The sum of the weights of all energetic compositions contained in

munitions hazard classified as HD 1.1 or 1.5 shall be used.

C10.4.1.2.1.2. The sum of the explosive weight of all HD 1.2 AE shall be used.
The propellant weight of a HD 1.2 item (if present) may be disregarded.

C10.4.1.2.1.3. The weights of energetic compositions hazard classified as HD 1.3

may be disregarded. However, if the site only contains HD 1.3 items, the criteria contained in
paragraph C9.4.3. apply.

C10.4.1.2.1.4. The weights of energetic compositions classified as HD1.4 may be

disregarded.

C10.4.1.2.1.5. The explosive weight of HD 1.6 shall be computed as follows:

216 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C10.4.1.2.1.5.1. When HD 1.6 is stored alone or with HD 1.4 AE, the QD

criteria of paragraph C9.4.3. apply.

C10.4.1.2.1.5.2. When HD 1.6 is stored with AE classified as HD 1.1, HD

1.2, or HD 1.5, add the explosives weight of the HD 1.6 items into the NEWQD calculations.

C10.4.1.2.1.5.3. When HD 1.6 is stored with AE classified as HD 1.3 add the

explosives weights of HD1.3 and HD 1.6. The QD criteria in paragraph C9.4.3. apply.

C10.4.1.2.2. Explosives Limits

C10.4.1.2.2.1. The maximum NEWQD at any BLAHA in a BLSA storing mixed

compatibility must not exceed 8,818 lbs [4,000 kg]. A BLSA may have multiple 8,818-lb [4,000
kg] BLAHA, provided the BLAHA are separated from each other by the applicable distances
(D1, D2 and D3) given in Table C10.T1.

C10.4.1.2.2.2. When the NEWQD of a BLSA or a BLAHA exceeds 8,818 lbs

[4,000 kg], the QD computations and HD mixing rules for the site shall be IAW Chapter 9 and
the explosives compatibility storage criteria shall be IAW Chapter 3.

C10.4.1.2.3. QD Computations

C10.4.1.2.3.1. The total NEWQD of AE in each site shall be used for

computation of QD provided the required distances (Table C10.T1.) necessary to prevent
propagation separate these sites. If the separation distances are not met, the entire BLSA shall be
considered one site and subparagraph C10.4.1.2.2.2. applies.

C10.4.1.2.3.2. The IMD requirements of Chapter 9 apply when using 3-Bar or 7-

Bar ECM.

C10.4.1.2.3.3. Table C10.T1. contains the QD separation for BLAHA and BLSA.

C10.4.1.2.3.4. Heavy armored vehicles are expected to contain most of the blast
and fragments from an internal explosion and are well protected from an external explosion. For
this reason there is no required separation from heavy armor PES to light or non-armored ES.
Additionally, heavy armor ES require no separation from other sites. The hatches of heavy
armored vehicles must be kept closed to be considered as heavy armor vehicles; otherwise, they
are considered as light armor vehicles. Use Table C10.T2. to determine the applicable QD for
heavy, light and non-armored vehicles.

DoD 6055.09-STD, February 29, 2008

C10.4.2.2.2. An explosives anchorage shall be located at K40 [15.87] from all piers.
However, where necessary for security or navigational reasons, this distance may be reduced to
ILD (K18 [7.14]) when the piers are only used for DoD operations. PTRD may be applied for
asset preservation. A separation distance of K40 [15.87] shall be maintained to all non-DoD
related piers.

C10.4.2.2.3. ILD (K18 [7.14]) is permitted between an explosives anchorage and a

non-explosives DoD-related anchorage. K40 [15.87] shall be maintained between an explosives

C10.4.2.3.2. Marshalling Yards. PTRD shall be maintained between marshalling

yards and explosives piers or AE holding areas. The location of the marshalling yard will
typically be governed by the NEWQD at the other PES. When operational necessity dictates,
marshalling yards may be separated by ILD (K18 [7.14]) to any nearby manned explosives
operations and AGM IMD (K11 [4.36]) to any nearby unmanned explosives storage operations.

C10.4.2.3.3. Loading Docks. Loading docks shall be sited at IMD (K11 [4.36]) from
all ES.

C10.4.2.3.4. Classification Yards. Use criteria provided in paragraph C9.8.2.

C10.4.2.3.5. Railheads. Based on its use, a railhead shall be sited as a classification

yard, AE holding area, or a loading dock.

C10.4.3. Field Storage and Handling Areas. These areas shall be sited IAW Table C10.T3.
Use separation distances from the applicable QD tables in Chapter 9 for the HD and NEWQD of
the AE involved with the PES. AE will be segregated IAW Chapter 3 by storage CG. The clear
zone surrounding the field storage and handling areas is bounded by the applicable IBD. No
unrelated, occupied structures are permitted within this zone.

222 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C10.4.3.1. These areas may consist of all or some of the following explosives locations:

C10.4.3.1.1. Field Storage Sections. These sections are used to store AE. Field
storage sections are used for dispersing AE in multiple, widely-separated storage sections; this
arrangement protects the loss of other sections from the loss of any one section, which would
seriously degrade the mission. AE may be stored in existing structures, caves, and tunnels as
prescribed in Chapter 9. The construction and use of barricades and revetments shall be IAW
Chapter 5.

C10.4.3.1.2. AE Staging Area. These areas are normally used for temporary holding
of outgoing AE and for ready access to Combat Aircraft Loading Areas (CALA).

C10.4.3.1.3. Captured Enemy Ammunition Area. A separate area shall be provided

for the storage of captured enemy AE. Captured enemy AE that cannot be identified shall be
treated as HD 1.1.

C10.4.3.1.4. AE Operations Area. An area used for operations such as minor

maintenance and repair of AE or their containers, surveillance, segregation, or weapons
assembly.

C10.4.3.1.5. AE Destruction Area. An area used for disposal of AE. It may consist
of a burning area, a demolition area, or both.

C10.4.3.1.6. Sling-out Area. An area used for moving AE by rotary-wing aircraft.

C10.4.3.2. These areas may consist of all or some of the following non-explosives
locations:

C10.4.3.2.1. Administration and Billeting Areas. Inhabited locations not directly

related to the daily operations of the field storage and handling areas.

C10.4.3.2.2. Manned Support Facilities. Facilities directly supporting AE operations

(e.g., field offices and AE support equipment maintenance facilities).

C10.4.3.2.3. Unmanned Support Facilities. Unmanned locations supporting AE

operations (e.g., forklift charging stations, dunnage storage, and buildings that store inert
materials). A minimum 50 ft [15.2 m] separation distance shall be maintained from these
locations to any PES.

C10.4.3.3. Modular Storage. A barricaded area comprised of a series of connected cells

with hard surface storage pads separated from each other by barricades (see paragraph C5.2.2.).

C10.4.3.4. Commercial Intermodal Containers (CIC). Containers used for transporting

AE may be used for AE storage and shall be sited as AGM.

Notes for Table C10.T3.:

N/R = Not Required
1. The distance criteria in the upper half of each row are the minimum separation distances required per Chapter 9.
The distance criterion in the lower half of each row is the asset preservation distance. For HD 1.1 material, use d
=24W1/3 [9.52 W1/3] [English EQN C10.T3-1] [Metric EQN C10.T3-2] or d=30W1/3 [11.90 W1/3] [English EQN
C10.T3-3] [Metric EQN C10.T3-4]. For HD 1.2, 1.3, or 1.4 apply PTRD from Chapter 9.
2. PTRD includes minimum fragment distance.
3. IBD includes minimum fragment distance.
4. IAW paragraphs C9.8.3. and C9.8.4.

C10.4.4. FARP. Storing AE and fuel at the same location is inherently hazardous and
should be avoided when possible. If it is necessary to refuel and rearm aircraft at the same
location, all precautions must be made to minimize the hazards involved in these operations.
Armament pads shall contain the minimum amount of AE to conduct efficient operations. For
example, where armament pads support only one aircraft, that pad shall be restricted to the
amount of ammunition necessary to rearm that aircraft.

224 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C10.4.4.1. Required Separations

C10.4.4.1.1. Use K24 [9.52] for asset preservation between FARP and other ES.

C10.4.4.1.2. FARP shall be separated by IBD from all non-associated inhabited

buildings.

C10.4.4.1.3. AE-ready storage (i.e., AE staged to support the next load) shall be
separated by AGM IMD from the armament pads with only armament pads considered as the
PES. Ready AE storage structures and locations shall be separated from other ready AE storage
structures and locations by AGM IMD.

C10.4.4.1.4. Build-up locations shall be separated by AGM IMD from all other
explosives storage and operations with only the build-up locations considered as the PES.

C10.4.4.1.5. Distances prescribed by the owning DoD Component shall separate

other support structures and sites.

C10.4.4.1.6. AE shall be separated from operational fuel supplies by at least 100 ft

[30.5 m]. Fuel supplies shall be diked or placed downhill from AE.

C10.4.5. Airfield Operations. Special consideration must be given to phased plans where the
peacetime operation and positioning of aircraft transitions to contingency operations with
increased quantities and use of AE. Exposures given adequate protection under the peacetime
phase may be at greater risk during the contingency phase. Commanders must consider these
changes when approving these plans. The proper use of such features as barricades or earth-
filled, steel-bin-type barricades (ARMCO revetment or equivalent (see section C5.3.)) can
decrease the magnitude of a potential event and increase the explosives capacity of limited areas.

C10.4.5.1. Airfield QD Criteria for PES. Table C10.T4. provides criteria for airfield
PES.

C10.4.5.2. Airfield QD Criteria for ES

C10.4.5.2.1. Runways, Taxiways and Aircraft

C10.4.5.2.1.1. For military use only, use Table C10.T4.

C10.4.5.2.1.2. For joint use, use criteria in Table C9.T24.

C10.4.5.2.2. Combat Aircraft Support Facilities

C10.4.5.2.2.1. Unhardened combat aircraft support facilities shall be separated

from AE storage and operating facilities by K30 [11.9]. For asset preservation, apply
incremental K40 [15.87] to K50 [19.84] based on the NEWQD.

225 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C10.4.5.2.2.2. If these functions are located in a HAS, separation may be reduced

to K18 [7.14] to the sides or rear of the HAS.

C10.4.5.2.2.3. Other hardened facility sitings require DDESB approval.

C10.4.5.2.2.4. When operational necessity dictates, separation distances less than

K18 [7.14] may be approved for ES; however, it must be demonstrated that protection equivalent
to K18 [7.14] is being provided.

C10.4.6. Static Missile Battery Separation. To ensure optimal effectiveness, offensive and
defensive missile batteries many times must be deployed in a static (non-mobile role) in the
proximity of other AE operations such as field storage or flight lines. The following criteria
apply to deployed static missile batteries and associated support functions:

C10.4.6.1. IMD (K11 [4.36]) shall be maintained between missile launchers, reloads and
other AE storage locations to include parked AE-loaded aircraft.

C10.4.6.2. Missile batteries deployed within the IBD of AE storage areas may be sited at
K18 [7.14] to manned functions considered related to area AE operations. Likewise, missile
batteries deployed in the clear zones of flight line operations may be sited at K18 [7.14] to
manned flight line facilities.

C10.4.6.3. Those functions solely providing support to static missile units, such as motor
pools, may be sited at K18 [7.14] to batteries and other AE activities when the missile battery is
located in these areas. For asset preservation, use PTRD.

C10.4.6.4. No separation is required between missile batteries and the security force
structures exclusively supporting them.

C10.4.7. Emergency Destruction. When it becomes necessary to destroy stores of AE to

prevent them from falling to the enemy, care must be taken to ensure that assets otherwise not in
danger of falling to the enemy are not destroyed by blast or fragments. The DoD Components
shall develop specific guidance for the implementation of and training for emergency destruction
of munitions. Normal disposal operations shall be conducted IAW paragraphs C9.8.3. and
C9.8.4.

C10.4.8. Separation From Fuel

C10.4.8.1. Operational Storage. Quantities up to 500 gallons [1,893 liters] shall be

separated from each PES by at least 50 ft. [15.24 m]. Quantities between 500 to 5,000 gallons
[1,893 to 18,927 liters] shall be separated from each PES by at least 100 ft. [30.5 m]. Fuel
should be located downhill and diked to contain a possible fuel spill.

C10.4.8.2. Bulk Fuel Storage. For more than 5,000 gallons [18,927 liters] apply
paragraph C9.8.14.

227 CHAPTER 10
DoD 6055.09-STD, February 29, 2008

C11. CHAPTER 11
TOXIC CHEMICAL MUNITIONS AND AGENTS

C11.1. SCOPE AND APPLICABILITY

C11.1.1. This chapter sets forth standards for protecting workers and the general public from
the harmful effects of toxic chemical munitions and agents associated with research, testing,
training, preservation and maintenance operations, storage, and demilitarization at laboratories,
manufacturing plants, and depots as well as other DoD Component agent operations, exclusive
of combat training and operations. They apply to:

C11.1.1.1. Blister agents (examples include, but are not limited to):

C11.1.1.1.1. H/HD – 2,2’ Dich1orodiethyl Sulfide (common name is distilled

mustard).

C11.1.1.1.2. H/HT – 60 percent HD and 40 percent 2,2’ Dichloroethylthiodiethyl

Ether (common name is mustard-T mixture).

C11.1.1.1.3. L – Dichloro (2-chlorovinyl) Arsine (common name is Lewisite).

C11.1.1.2. Nerve agents (examples include, but are not limited to):

C11.1.1.2.1. GB – Isopropyl Methylphosphonofluoridate (common name is sarin).

C11.1.1.2.2. GA – Dimethylaminoethoxy-cyanophosphine Oxide (common name is

tabun).

C11.1.1.2.3. VX – 0-ethyl S-[2-(diisopropylamino) Ethyl] Methylphosphonothioate.

C11.1.1.2.4. GD – Pinacolyl Methylphosphonofluoridate (common name is soman).

C11.1.1.2.5. Mixtures of these agents.

C11.1.2. Toxic chemical munitions may present additional hazards of blast, fragments, and
thermal effects. Standards relating to these explosives hazards are addressed in other chapters.

C11.1.3. This standard does not apply to the immediate disposal of toxic chemical munitions
or decontamination of toxic chemical agents during an emergency when the delay will cause a
greater danger to human life or health.

C11.1.4. The DoD Components are responsible for developing implementing instructions
and safety procedures for logistical movements, training, and field operations.

C11.1.5. The requirements of MIL-STD-882D (Reference (ab)) shall be followed.

228 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

C11.2. SITING CRITERIA

C11.2.1. Hazard Distance Calculations (See Public Exclusion Distance). Hazard distance
calculations shall conform to Reference (q). DDESB approved software (e.g., D2PC (Reference
(ac))) that implements the methodology of Reference (q) may be used to perform these
calculations. The calculated hazard distance is based on the greater of the MCE or the toxic
chemical agent MCE and is bounded by the one percent lethality arc for a toxic chemical agent
source containing a dose of more than:

C11.2.1.1. 10.0 mg-min/m3 of GB.

C11.2.1.2. 4.3 mg-min/m3 of VX.

C11.2.1.3. 150.0 mg-min/m3 mustards.

C11.2.1.4. 0.1 mg for inhalation-deposition of VX.

C11.2.2. Positive means shall be taken to ensure that unprotected personnel do not enter
hazard zones and shall include written procedures that must be reviewed and updated, as
necessary. However, positive control of an area, which ensures personnel can evacuate or be
protected before exposure in the case of an accident, may be developed instead of absolute
exclusion. Details of such control procedures shall be included in the site and general
construction plans.

C11.3. WORKPLACE AIRBORNE EXPOSURE LIMITS (AEL)

The Army Surgeon General establishes the maximum permissible concentrations (AEL) listed in
Table C11.T1. AEL are time-weighted averages (TWA) or ceiling values that define the
permissible limits of exposure for unprotected personnel.

229 CHAPTER 11

Notes for Table C11.T1.:

1. All concentrations measured as Lewisite.
2. This value also represents the technologically feasible real time detection limit. HT is measured as HD.
3. It is recommended that this level of detection (using a 12-hour sampling time) be demonstrated and used at all
sites where mustard shall be transported and destroyed.
4. The concentration of chemical agent that may not be exceeded for any period of time. Practically, it may be an
average value over the minimum time to detect the specified concentration.

C11.4. TOXIC CHEMICAL AGENT HAZARD ANALYSES, MEASUREMENTS, AND

EXPOSURE CONTROLS

C11.4.1. Hazard Analyses

C11.4.1.1. Hazard analyses shall be conducted for all new operations involving toxic
chemical agents or when there is a change in existing production, process, or control measures
that may result in an increase in airborne or contact concentrations of toxic chemical agents.
Hazard analyses shall be retained for 40 years.

C11.4.1.2. If hazard analyses indicate that an operation may expose personnel to toxic
chemical agents above the AEL, control measures shall be instituted and procedures shall be
established so that the actual exposure is measured.

C11.4.2. Measurements

230 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

C11.4.2.1. Devices for sampling and analyzing workplace air shall measure and alarm
within 10 minutes when toxic chemical agents are present in excess of the 8-hour TWA
concentrations.

C11.4.2.2. When the interior of reservoirs, pipes, and such systems are sampled, the
volume of the item or system being sampled as well as the volume of the sample must be
recorded and associated with the measured concentrations.

C11.4.2.3. Decontaminating solutions shall not be analyzed for residual toxic chemical
agent for the purpose of certifying a level of decontamination. Suspected toxic chemical agents
shall be extracted from samples with suitable solvents where analyses are required. Air may be
an appropriate solvent for volatile agents.

C11.4.3. Exposure Control

C11.4.3.1. When exhaust systems are used to control exposure, measurements of system
effectiveness such as static pressure shall be made at the start of each operation and at least every
3 months.

C11.4.3.2. Before beginning toxic chemical agent operations, the hazard zone associated
with those operations shall be under positive control in accordance with paragraph C11.2.2.

C11.4.3.3. If personnel exposures will equal or exceed the applicable AEL, personnel
shall be protected by personnel protective equipment (PPE) specifically approved by the Army
Surgeon General or as indicated in Table C11.T2.

C11.4.3.4. Procedures shall be developed to address hazards involved in maintenance

and repair operations.

3a above is not available, use of a full
facepiece, chemical canister, air purifying
protective mask with hood is acceptable.
Only the M9 or M40 series masks
are acceptable.
(Notes 7 & 8)

Notes for Table C11.T2.:

1. Qualitatively fit all workers required to use respiratory protective devices. Quantitative fit testing may be
performed using surrogate masks.
2. Employee exposure potential is based on an 8-hour TWA measurement. All values on this table are 8-hour
TWA unless otherwise noted. The TWA is the concentration to which workers may be repeatedly exposed, for
a normal 8-hour workday and 40-hour workweek, day after day, without adverse effects. TWA permit

232 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

excursions above the limit provided they are compensated by equivalent excursions below the limit during the
workday. Excursions above the TWA should be controlled even where the 8-hour TWA is within
recommended limits.
3. Determined by required continuous air monitoring.
4. This represents ceiling value determined by continuous real time monitoring (with alarm) at the 0.003 mg/m3
level of detection. Respiratory protection must be immediately available in case concentration rises above
0.003 mg/m3. Engineering and work practice controls shall be used to limit employee exposure potential to the
extent practical.
5. Air-purifying masks may not be used in oxygen deficient atmospheres.
6. Because agents H and L are potential carcinogens, the highest level of respiratory and dermal protection shall be
provided to all workers exposed. An air-purifying protective mask is not suitable for this purpose.
7. Examples of such protective ensembles include Toxicologic Agent Protective Ensemble, Self-Contained
(TAPES) and the Demilitarization Protective Ensemble (DPE).
8. For emergency masked escape, a full facepiece, chemical canister, air-purifying protective mask (DoD
Component-certified masks) is acceptable.

C11.5. MEDICAL SURVEILLANCE

Before being assigned to toxic chemical agent duties and on an annual basis thereafter, health
assessments shall be provided for each employee to establish a baseline health record. Annual
assessments shall be used to determine deviations from the baseline.

C11.6. WORKER PPE

C11.6.1. Positive engineering and administrative controls shall be incorporated in all

operations involving toxic chemical agents to preclude or minimize the need for PPE.

C11.6.2. A respiratory protection program shall be established in conformance with DoD

Instruction 6055.1 and DoD Instruction 6055.5 (References (ad) and (ae)) for approved
respiratory requirements. The wearer’s face shall be clean-shaven to the extent that there is no
interference of any facial hair growth with the sealing surfaces of the protective mask. Personnel
with beards shall be denied access to agent storage and operating areas, unless suitable
emergency egress respirator(s) can be provided.

C11.6.3. Personnel shall use PPE recommended by the hazard analysis. (See Table C11.T2.)

C11.7. ADMINISTRATIVE AND WORK PRACTICE CONTROLS

C11.7.1. Containment

C11.7.1.1. Containment is the principal control measure for prevention of exposure of

personnel to toxic chemical agents.

C11.7.1.1.1. Total containment is required for those operations involving toxic

chemical munitions that contain explosive components when the operation may subject the
explosives components to a potential initiating stimulus. Total containment requires the

233 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

equipment or facility to be a DDESB-approved design capable of containing all the reaction

gases, detectable toxic chemical agents, and fragments from the largest explosion or detonation
that could occur without causing equipment or facility rupture or leakage. Operations requiring
total containment include, but are not limited to:

C11.7.1.1.1.1. Toxic chemical munition cutting, sawing, milling, drilling,

punching, or shearing operations that require the machine tool to remove or displace metal
before or after contact with the explosives.

C11.7.1.1.1.2. Operations in which the toxic chemical munition arming and

functioning environments can be duplicated by the equipment or process.

C11.7.1.1.1.3. Disassembly of armed or possibly armed toxic chemical

munitions.

C11.7.1.1.1.4. Disassembly of explosive components from toxic chemical

munitions that requires application of significantly greater leverage or torque than that required
for assembly.

C11.7.1.1.2. Vapor containment is required for those operations involving toxic

chemical agents without explosives components and for those operations involving toxic
chemical munitions containing explosive components that do not subject the explosive
components to a potential initiating stimulus. Vapor containment requires the equipment or
facility to be a DDESB-approved design capable of containing non-explosion releases of toxic
chemical agents. Operations requiring vapor containment include, but are not limited to:

C11.7.1.1.2.1. Toxic chemical munitions punching, drilling, or sawing operations

for removal of toxic chemical agents.

C11.7.1.1.2.2. Burster-well removal.

C11.7.1.1.2.3. Transfer of toxic chemical agents from bulk storage tanks,

containers, or toxic chemical munitions into holding tanks, chemical detoxification reactors,
incinerators, or similar processing equipment (e.g., may be found in a production,
demilitarization, or disposal line).

C11.7.1.1.2.4. Research, development, test, and evaluation (RDT&E) chamber

operations.

C11.7.1.2. Containment is not required for operations associated with field storage and
maintenance activities (e.g., shipping, storage, receiving, re-warehousing, minor maintenance,
surveillance inspection, repair, and encapsulation).

C11.7.2. Training and Information. Anyone who works with toxic chemical munitions and
agents (e.g., agent workers, firefighters, medical and security personnel) shall receive training to
enable them to work safely and to understand the significance of toxic chemical agent exposures.

234 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

This training shall include, but is not limited to, information on sources of exposure, adverse
health effects, practices and controls used to limit exposures, environmental issues, medical
monitoring procedures, and employee responsibilities in health protection programs.

C11.7.3. Recordkeeping. Recordkeeping pertaining to exposure determination and

measurement, mechanical ventilation, employee training, medical surveillance, and access to
records shall be consistent with Reference (ae).

C11.7.4. Labeling and Posting of Hazards

C11.7.4.1. Signs and labels to warn personnel of hazards of toxic chemical agents are
required for:

C11.7.4.1.1. Work areas.

C11.7.4.1.2. Contaminated clothing and equipment.

C11.7.4.1.3. Identification of restricted-use areas.

C11.7.4.2. When items or materials are contaminated or suspected of being contaminated

with toxic chemical agents, they shall be marked as follows:

C11.7.4.2.1. The applicable supplemental chemical hazard symbol (see Figure

C8.F3.) with “XXXXX” indicates that the items or materials have been completely
decontaminated and may be released for general use or sold to the general public. Items or
materials are completely decontaminated when they have been subjected to procedures that are
known to completely degrade the toxic chemical agent molecule, or when analyses, approved by
the DDESB, have shown that the total quantity of toxic chemical agent is less than the minimal
health effects dosage as determined by the Office of the Surgeon General of the Army.

C11.7.4.2.2. The applicable supplemental chemical hazard symbol (see Figure

C8.F3.) with “XXX” indicates that the items or materials have been decontaminated. Tests or
monitoring shall be conducted in accordance with DoD Component requirements to verify that
concentrations do not exceed the AEL for an unmasked agent worker in Table C11.T1.

C11.7.4.2.3. The applicable supplemental chemical hazard symbol (see Figure

C8.F3.) with a single “X” indicates the items or materials have been partially decontaminated of
the indicated toxic chemical agent. Further decontamination processes are required before the
item is moved or any maintenance or repair is performed without the use of PPE.

C11.7.4.3. When facilities or rooms are contaminated or suspected of being

contaminated with toxic chemical agents, they shall be marked as follows (excluding magazines
that use the supplemental chemical hazard symbols shown in Figure C8.F3.):

C11.7.4.3.1. 5R – No Agent Hazard. A supplemental chemical hazard symbol (see

Figure C8.F3.) with “RRRRR” indicates that all previously contaminated surfaces are

235 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

decontaminated and analyzed to demonstrate the absence of residual toxic chemical agents, and
air sampling indicates toxic chemical agent vapor concentration is less than the 8-hour TWA for
an unmasked agent worker (see Table C11.T1.). The air is sampled at a temperature of 70 °F
[21.1 °C] or greater, with the facility’s ventilation system operating.

C11.7.4.3.2. 4R – Controlled Agent Vapor Hazard. A supplemental chemical hazard

symbol (see Figure C8.F3.) with “RRRR” indicates that all previously contaminated surfaces are
decontaminated using locally approved procedures and air sampling indicates toxic chemical
agent vapor concentration is less than the 8-hour TWA for an unmasked agent worker (see Table
C11.T1.). The air is sampled at a temperature of 70 °F [21.1 °C] or greater, with the facility’s
ventilation system operating.

C11.7.4.3.3. 3R – Contained Agent Hazard. A supplemental chemical hazard

symbol (see Figure C8.F3.) with “RRR” indicates that any toxic chemical agents are in
containers or packaging which, if left undisturbed, will prevent agent vapor or contact hazards.

C11.7.4.3.4. 2R – Agent Vapor Hazard. A supplemental chemical hazard symbol

(see Figure C8.F3.) with “RR” indicates that any toxic chemical agents are in containers or
packaging which, if left undisturbed, prevent contact hazards.

C11.7.4.3.5. lR – Agent Hazard. A supplemental chemical hazard symbol (see

Figure C8.F3.) with “R” indicates the possibility of toxic chemical agent contact or vapor
hazards, or agents in a single container or packaging that may leak. This includes rooms being
used for operations that may cause agents to be released from engineering controls due to
accidental causes.

C11.7.5. Emergencies

C11.7.5.1. In case of an accidental release of a toxic chemical agent that may result in
personnel exposure, all nonessential and unprotected personnel shall evacuate immediately.
Contaminated areas shall be decontaminated to applicable Table C11.T1. AEL before normal
operations are resumed.

C11.7.5.2. Special medical surveillance shall be started within 24 hours for all personnel
present in the potentially affected area at the time of the emergency.

C11.7.5.3. The DoD Component shall maintain up-to-date chemical accident and
incident control plans and conduct practice exercises of these plans at least annually.

C11.7.6. Toxic Chemical Agent Decontamination

C11.7.6.1. When toxic chemical agents are spilled or released, immediate action shall be
taken to contain the spill and clean up the agent in the immediate area of the spill.

C11.7.6.2. Before leaving contaminated work areas, the external surfaces of the PPE
shall be decontaminated.

236 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

C11.7.6.3. When PPE becomes contaminated with toxic chemical agents, the outside
layer of clothing shall be removed and decontaminated as soon as possible.

C11.7.6.4. PPE that has been worn in known contaminated areas (toxic chemical agent
detected) shall be decontaminated and monitored before reuse. Because mustard penetrates into
many protective materials with time, reuse of any PPE that has been contaminated with liquid
mustard is not permitted. PPE that has been worn in potentially contaminated areas (when no
agent leakage has been visually observed or detected by use of field detection equipment) shall
be monitored before being moved to areas accessible to non-agent workers.

C11.7.6.5. Monitoring of protective clothing and equipment shall include

containerization at 70 °F [21.1 °C] or higher for at least 4 hours, with subsequent analysis of a
portion of the interior atmosphere of the container for the toxic chemical agent. The volume of
the container as well as the sample volume must be noted.

C11.7.6.6. PPE found to emit toxic chemical agent concentrations above the XXX level
after decontamination shall not be reused. They shall be disposed of in accordance with DoD
Component guidance and in compliance with all Federal, State, and local requirements.

C11.7.6.7. The piping, tanks, etc., of the disposal systems shall be filled with
decontaminating solution and a contact time of 10 half lives or greater shall be provided before
toxic chemical agent disposal systems are converted to different agents. Walls and floors of
process areas shall be decontaminated to ensure the absence of contact hazards.

C11.7.7. Recertification of Protective Clothing. After decontamination, clothing that has

been determined to be XXX may be laundered, visually examined, and re-certified by the DoD
Component for use. Other PPE, such as boots and gloves, shall be tested, laundered, and re-
certified for use in the same manner.

C11.7.8. Transportation of Items or Materials Contaminated with Toxic Chemical Agents.

Items or materials contaminated with toxic chemical agents may be transported from one
location to another. They shall be encapsulated within an agent-tight barrier. In addition, the
following items or materials shall be overpacked in compatibly lined drums or provided with
other suitably tested containment before being transported:

C11.7.8.1. Contaminated potentially with liquid toxic chemical agent.

C11.7.8.2. Failed a XXX determination.

C11.7.8.3. Suspected of offering hazards due to skin exposure to a toxic chemical agent.

C11.7.9. Transportation of Toxic Chemical Munitions and Bulk Agents. The requirements
established by the DoD Component shall be met.

DoD 6055.09-STD, February 29, 2008

The chemical handling and maintenance areas associated with industrial operations shall be
isolated from the main facility and shall be operated at a negative pressure with respect to the
main facility area. The agent handling rooms shall be equipped with local exhaust ventilation
which may be cascaded to more contaminated areas and exhausted out of a common exhaust
stack. All air leaving the facility shall be filtered through redundant filter banks or other
DDESB-approved decontamination methods. The flow of air (negative pressures) shall go from
less-hazardous areas to more-hazardous areas.

C11.8.1. Air Ventilation Systems. Air ventilation systems shall be designed and periodically
tested to ensure that control of toxic chemical agent-contaminated exhaust shall not exceed
source emission limits of Table C11.T1.

C11.8.1.1. Filters or scrubbers for exhaust air shall be designed and approved for the
MCE of the operations involved.

C11.8.1.2. Redundant filters shall be used when filter breakthrough of the toxic chemical
agent is expected. Filters shall be changed when agent breaks through the filter that is just
upstream of the last filter.

C11.8.1.3. All exhaust equipment shall have backup blowers that automatically engage if
the main blower fails.

C11.8.1.4. Filter systems shall be fitted with the means to measure the pressure drop
across the filters.

C11.8.1.5. Exhaust hoods and glove boxes shall be designed to contain toxic chemical
agents so that concentrations specified in Table C11.T1. for unmasked agent workers are not
exceeded outside engineering controls. The design of these items shall permit airflow
adjustments sufficient to maintain the required protection level when laboratory equipment is in
place.

C11.8.1.5.1. Catch basins and traps or spill trays of sufficient capacity to contain the
quantity of toxic chemical agent involved shall be provided within hoods and glove boxes.

C11.8.1.5.2. Glove boxes shall be used when the hazards analysis indicates that toxic
chemical agent aerosols or dusts may be present during an operation.

C11.8.1.6. Special design features shall be used when exposed explosives are involved to
segregate explosives from air ventilation systems.

C11.8.2. Mechanical and Utilities Design for Facilities

C11.8.2.1. The design parameters shall consider equipment and process layout, makeup
airflow, and operational positions with regard to maintaining flow balance and cross currents.

238 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

The system shall maintain negative pressure in operating areas in relation to hallways, offices,
and other nontoxic chemical agent areas.

C11.8.2.2. Working surfaces, walls, floors, and ceilings within a facility likely to be
contaminated shall be constructed of agent-resistant materials. Flooring material shall cover wall
surfaces to a height of 6 in [15.2 cm].

C11.8.2.3. Access to nontoxic chemical agent areas (e.g., utilities, mechanical rooms,
etc.) shall be accomplished without entry into toxic chemical agent areas.

C11.8.2.4. Electrical systems shall be equipped with a backup power source designed to
start automatically and supply sufficient power to support critical functions in the event of power
outage.

C11.8.2.5. Safety showers and eyewash fountains shall be readily accessible and tested.

C11.8.2.6. Water outlets in a toxic chemical agent operational facility shall be fitted with
backflow devices.

C11.8.2.7. Dedicated liquid waste systems shall be designed to collect and hold
potentially toxic chemical agent-contaminated effluent produced by the activity until disposal in
accordance with applicable laws. Vents or other openings in the waste system shall be fitted
with approved toxic chemical agent filters or connected or exhausted to facility toxic chemical
agent air filtration system.

C11.8.2.8. Decontamination facilities of sufficient capacity to catch and contain liquid

effluents shall be provided for toxic chemical agent operations. Adequate decontamination
solution shall be available for immediate use on personnel or on facilities.

C11.8.2.9. When operations require work assignments to be conducted at exposure levels

above or potentially above the AEL for unmasked agent workers (see Table C11.T1.), change
facilities with showers shall be provided.

C11.8.3. General Design Considerations

C11.8.3.1. Facility Alarms and Monitors for Engineering Systems. Each toxic chemical
agent facility shall have a master alarm and control panel that will permit functional verification
of the exhaust blowers and air handlers. Visual and audible alert alarms shall be keyed to this
master alarm panel to indicate failures.

C11.8.3.2. Fire Detection and Protection. Fire detection and protection systems for
production and maintenance facilities shall comply with the requirements and guidelines
published in ARLCD-CR-80049 (Reference (af)).

C11.8.3.3. Bulk Storage Tanks. Impermeable dikes to hold at least 110 percent of the
tank capacity, plus the required volume of decontaminant solution, shall be placed around all

239 CHAPTER 11
DoD 6055.09-STD, February 29, 2008

bulk agent tanks, reactors, and mixers. However, a system designed to pump the toxic chemical
agent from the dikes to a vessel designed to accommodate the decontamination will satisfy this
requirement that the dike contain sufficient volume for the decontaminating solutions.

C11.8.3.4. Isolation of Facility Functions. Toxic chemical agent facilities shall be

designed to isolate unrelated activities by physical barriers or approved engineering controls.
Design criteria shall prevent explosives from entering drain lines and sumps containing toxic
chemical agents.

C11.8.3.5. Monitoring. Air monitoring stations shall be established around toxic

chemical agent operational areas and storage areas to determine if Table C11.T1. AEL are
exceeded. In laboratory environments this requirement is met by routine area monitors and stack
sampling.

C11.8.3.5.1. Monitoring analyses conducted for the purpose of demonstrating

compliance with AEL shall be based on DoD Component-certified reference materials.

C11.8.3.5.2. Monitoring analyses conducted for the purpose demonstrating

compliance with AEL shall be conducted under quality assurance plans that address the
following issues:

C11.8.3.5.2.1. Production, characterization, and storage of DoD Component-

certified reference materials.

C11.8.3.5.2.2. Documentation of precision, accuracy, and quantification limits of

analytical methodology.

C11.8.3.5.2.3. External oversight of laboratory results.

C12. CHAPTER 12
REAL PROPERTY KNOWN OR SUSPECTED TO CONTAIN MUNITIONS AND
EXPLOSIVES OF CONCERN AND CHEMICAL AGENTS

C12.1. SCOPE

This chapter:

C12.1.1. Establishes explosives safety standards that, when applied, will protect people and
real property from explosive and CA hazards associated with:

C12.1.1.1. Real property known or suspected to contain:

C12.1.1.1.1. Munitions and explosives of concern (MEC).

C12.1.1.1.2. CA in other than munitions configurations (e.g., DoD laboratory vials,

CA identification sets, one-ton containers, CA-contaminated soil).

C12.1.1.2. Munitions responses to MEC. (A munitions response to CA-filled munitions

will be addressed as a chemical warfare material (CWM) response.)

C12.1.1.3. CWM responses.

C12.1.2. Establishes a process for determining site-specific actions that, when taken, will:

C12.1.2.1. Ensure explosives safety is addressed throughout munitions responses to

MEC.

C12.1.2.2. Ensure CA safety and, when applicable, explosives safety is addressed

throughout CWM responses.

C12.1.2.3. Result in DDESB approval of required safety submissions for munitions

responses to MEC and for CWM responses. (See section C12.5. for required safety submission
and their contents.)

C12.1.2.4. Document and report completion of:

C12.1.2.4.1. Munitions responses to MEC.

C12.1.2.4.2. CWM responses.

C12.1.3. Does not apply to:

C12.1.3.1. Operational ranges, with the exception of military munitions burial sites
located on such ranges.

241 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.1.3.2. Explosives or munitions emergency responses.

C12.2. EXPLOSIVES SAFETY STANDARDS FOR THE IDENTIFICATION AND

CONTROL OF AREAS KNOWN OR SUSPECTED TO CONTAIN MEC OR CA

To ensure explosives and CA safety risk is identified and controlled on real property currently or
formerly under the jurisdiction, custody, or control of a DoD Component, DoD Components
must:

C12.2.1. Identify all areas known or suspected to present explosive or CA hazards

(Geographic Information Systems (GIS) should be used):

C12.2.1.1. In installation master plans for active installations. (In some cases, these
areas are also required to be identified in other documents.)

C12.2.1.2. In DoD’s Military Munitions Response Site Inventory for those sites that are
included in the Military Munitions Response Program (see Management Guidance for the
Defense Environmental Restoration Program (DERP) (Reference (ag)) and 10 U.S.C. 2710(a)
(Reference (ah))).

C12.2.2. Maintain permanent records of those areas identified pursuant to subparagraph

C12.2.1. and ensure such records are readily available to current and future users of the property.
Records should be retained for areas such as operational ranges, former ranges, current or former
munitions manufacturing facilities, current or former sites used for munitions demilitarization
activities, and locations previously used for the burial of munitions. Records shall:

C12.2.2.1. When practicable, include the nomenclature and the known or suspected
location.

C12.2.2.2. Summarize any clearance or response (removal or remediation) actions, or

explosives or munitions emergency responses previously conducted within the area.

C12.2.3. Prohibit unnecessary access and take appropriate action to deter unauthorized
access to areas under DoD control that are known or suspected of containing potential explosive
or CA hazards. Such actions may include establishing access controls (e.g., fencing the area,
establishing roving security patrols), which may be risk-based, or providing public notifications
of any potential hazards (e.g., posting unexploded ordnance (UXO)-hazard warning signs,
conducting UXO-safety education programs). When used, signs must be kept legible and, when
appropriate, in the predominant languages of the region, or as pictograms. When the Department
of Defense does not have ownership, jurisdiction, or control of the area (e.g., Formerly Used
Defense Sites (FUDS)), the responsible DoD Component shall, at a minimum, provide written
notification of the potential explosive or CA hazards to the property owner and any known
tenants. A record of this notification must be maintained as a permanent record. (See
subparagraph C12.2.2.)

242 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.2.3.1. DoD Components should, unless there is evidence to the contrary, assume the
following areas present explosive hazards:

C12.2.3.1.1. Impact areas on operational ranges. Exceptions are ranges known to

have been exclusively used for training with only small arms ammunition.

C12.2.3.1.2. Former ranges known or suspected to contain MEC.

C12.2.3.1.3. Outdoor demolition areas, to include locations used for open burning
(OB) or open detonation (OD).

C12.2.3.1.4. Areas that are associated with military munitions production,

demilitarization, renovation, or similar processes (e.g., operating buildings and any installed
equipment) that generated explosives residues (e.g., dust, vapors, liquids) and that might have
become contaminated with such residues in concentrations sufficient to present explosive
hazards, to include areas receiving processing wastewater (e.g., settling ponds, drainage swales).

C12.2.3.2. DoD Components should, unless there is evidence to the contrary, assume the
following areas present CA hazards:

C12.2.3.2.1. Former CWM or CA burial sites.

C12.2.3.2.2. Former CWM or CA disposal areas.

C12.2.3.2.3. Former CWM impact areas.

C12.2.3.2.4. Former training areas used for training with CWM or CA.

C12.2.3.2.5. Former CWM or CA production and demilitarization facilities.

C12.2.3.3. When access to areas known or suspected to present explosive or CA hazards

is necessary, a risk assessment to evaluate the potential hazards associated with the proposed
activity shall be completed and methods to mitigate any potential exposures shall be
implemented before access is allowed. (When access is necessary to real property not under
DoD ownership, custody, or control, the DoD Component should obtain a right of entry for the
property.)

C12.2.4. Prohibit the disposal (e.g., burying, dumping) of military munitions on land or in
water except when specifically authorized by the DoD Component. Such disposal actions must
comply with applicable regulatory requirements. This prohibition does not preclude:

C12.2.4.1. The covering of munitions with earth to control fragments and noise during
authorized destruction by detonation.

243 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.2.4.2. The use of in situ capping when implemented as an engineered remedy under
an authorized response action.

C12.3. EXPLOSIVES AND CA SAFETY ASPECTS OF RESPONSE ACTIONS

C12.3.1. General.

C12.3.1.1. Plans for munitions responses to MEC or CWM responses shall:

C12.3.1.1.1. Ensure close coordination, as applicable, between DoD explosives and

CA safety organizations, DoD environmental organizations, and appropriate regulatory agencies
and stakeholders.

C12.3.1.1.2. Specify those actions necessary to protect DoD personnel, installation-

related personnel, and the public from exposure to explosive and CA hazards.

C12.3.1.1.3. Provide the design for and explain the execution of:

C12.3.1.1.3.1. Munitions responses, when MEC has been determined to present

an unacceptable risk.

C12.3.1.1.3.2. CWM responses, when CA, regardless of configuration, has been

determined to present an unacceptable risk.

C12.3.1.1.4. Explain how the selected response actions will achieve a degree of
protectiveness necessary for the current, determined, or reasonably anticipated future land use.

C12.3.1.1.4.1. Provide the rationale for selection of technologies to be used to

detect anomalies that can indicate the presence of MEC or CA, regardless of CA configuration.

C12.3.1.1.4.2. Address how periodically (e.g., during 5-year reviews or

consistent with long-term monitoring agreements) completed response actions will be reviewed
to ensure the response remains effective. The need for such reviews is particularly important in
areas where natural phenomena (e.g., frost heave, soil erosion, droughts, or tidal action) could
expose MEC or CA, regardless of CA configuration, or where Land Use Controls (LUC)
constitute a major element of the response. These reviews shall consider:

C12.3.1.1.4.2.1. The explosives safety aspects of munitions responses to

MEC.

C12.3.1.1.4.2.2. The CA safety and, when applicable, the explosives safety

aspects of CWM responses.

C12.3.1.1.5. Address how the personnel qualification provisions of DDESB TP No.

18 (Reference (ai)) will be met.

244 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.3.1.1.6. Be approved by the DDESB for compliance with these Standards.

C12.3.1.1.7. Provide for the submission of an After Action Report (AAR) to the
DDESB upon completion of the response. AAR are not provided for DDESB approval, but are
used to close out files maintained by the DDESB Staff.

C12.3.1.2. Residual Explosive and CA Hazards

C12.3.1.2.1. Some areas that the military has used for munitions-related activities
(e.g., live-fire training or testing, OB/OD) or for CA-related activities may not be appropriate,
even after the performance of response activities, for certain uses (e.g., residential development).
Such areas include former military range impact areas on which the military has used munitions
containing either high explosives or CA and sites used for either OB or OD. Such areas may,
after a response, be better suited for uses that restrict or limit intrusive activities (e.g., wildlife
refuges, surface recreational areas).

C12.3.1.2.2. Some MEC or CA, regardless of CA configuration, might not be

detected or removed during a response. Although residual risks can be managed (e.g., by use of
agreed-upon LUC, to include safety education; recurring reviews; and construction support),
residual hazards might still exist.

C12.3.1.2.3. From an explosives and, when applicable, CA safety perspective, the

degree to which MEC or CA removal is undertaken depends largely on the current, determined,
or reasonably anticipated future land use. When MEC or CA, regardless of CA configuration,
cannot be removed to the degree necessary to safely allow the current, determined, or reasonably
anticipated future land use, the use must be changed or appropriately restricted to obtain DDESB
approval of the relevant plan.

C12.3.1.3. When DoD does not control the land and the imposition of LUC is not
possible (e.g., on FUDS), the responsible DoD Component should, at a minimum, provide the
property owner, and any known tenants, written notification of the potential residual explosive or
CA hazards and the risks inherent in any use of property that is inconsistent with those hazards.

C12.3.2. Explosives Safety and CA Safety Aspects in the Selection and Design of Responses

C12.3.2.1. Explosives safety must be addressed in the selection and design of a

munitions response to MEC. CA safety, and when applicable, explosives safety must be
addressed in the selection and design of a CWM response. The protection afforded by a
response must be consistent with the current, determined, or reasonably anticipated land use.
The design of the response that is included in the required submission must consider the site-
specific information below.

C12.3.2.1.1. Historical Information. Historical information, which is documented in

a written report, is gathered through a records search, to include the permanent records outlined
in section C12.2., and interviews. The following information is required:

245 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.3.2.1.1.1. The boundaries of the response area. For munitions responses, the
Munitions Response Area (MRA) boundaries and, when appropriate, the boundaries of any
Munitions Response Sites (MRS) (e.g., firing points, impact areas, and burial sites) within the
MRA are required.

C12.3.2.1.1.2. The type of MEC known or suspected to be present based on the

types of munitions-related operations, training, or testing previously performed in the MRA or
MRS.

C12.3.2.1.1.3. The type and configuration of any CA known or suspected to be

present.

C12.3.2.1.2. Land Use. Land use is the current, determined, or reasonably

anticipated future use of real property. Because portions of the response area (e.g., the MRA or
MRS) might be used differently (e.g., public highway, wildlife refuge, sports field, industrial
complex), different responses actions (e.g., surface removal, subsurface removal, no removal,
remedial response) may be appropriate within any given response area.

C12.3.2.1.2.1. Where the land use is, or will be, limited to surface activities, the
munitions or CWM response may only involve removing surface MEC or surface CA (i.e., a
surface removal). This removal may be technology-aided.

C12.3.2.1.2.2. When the land use will involve or allow intrusive activities to
occur, the response will normally require a subsurface removal, and may require follow-on
construction support.

C12.3.2.1.2.3. Where the current, determined, or reasonably anticipated land use

is compatible with the explosive or CA hazards present or suspected, a response action to remove
any explosive or CA hazards may not be necessary.

C12.3.2.1.2.4. Where a response would adversely impact natural or cultural

resources, a removal action may not be practical.

C12.3.2.1.3. Results of Onsite Investigations. These results should be used to

validate and augment information discovered during the historical review and to determine the
specific boundaries of the response area (e.g., the boundary of an MRA or of any MRS within an
MRA).

C12.3.2.1.4. Analysis. A detailed analysis of available records, technical data, and

the results of onsite investigations. This analysis should evaluate:

C12.3.2.1.4.1. The types of MEC or CA, regardless of CA configuration, known

to be present, to include its technical characteristics (e.g., filler, fuzing) and estimated
distribution.

246 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.3.2.1.4.2. The potential explosive or CA hazards present.

C12.3.2.1.4.3. Physical site characteristics (e.g., flora and fauna (including

endangered species), cultural, geological, topographical, hydrological).

C12.3.2.1.4.4. Persons potentially endangered.

C12.3.2.1.4.5. Information from previous or current responses.

C12.3.2.1.5. LUC. The appropriateness and effectiveness of LUC to manage any

residual explosives safety or CA safety risks.

C12.3.2.1.6. Technology. The applicability, capabilities, and limitations of available

technologies (e.g., detection, discrimination, removal).

C12.3.2.1.7. Other relevant factors.

C12.4. SPECIAL CONSIDERATIONS

C12.4.1. Explosive Soil

C12.4.1.1. Because of some past munitions-related activities (e.g., settling ponds or

explosives sumps at munitions production or demilitarization facilities), concentrations of
explosives in soil (e.g., sand, sludge, clay) can exist such that the mixture itself presents an
explosive hazard. Such mixtures are referred to as “explosive soil.”

C12.4.1.2. The NEWQD of explosive soil is the weight of the mixture multiplied by the
explosives concentration (e.g., 1,000 lbs [454 kg] of explosive soil that is 10 percent TNT has an
NEWQD of 100 lbs [45.4 kg]).

C12.4.1.3. The concentration necessary to present an explosive hazard depends on the

distribution and type of explosives in the soil and the soil’s characteristics.

C12.4.1.3.1. Primary (Initiating) Explosives

C12.4.1.3.1.1. Soil containing 2 percent or more by weight of any primary

explosive or mixture of primary explosives presents an explosive hazard and shall be treated as
HD 1.1.

C12.4.1.3.1.2. Soil containing less than 2 percent by weight of any primary

explosive does not present an explosive hazard.

C12.4.1.3.2. Secondary Explosives.

247 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.4.1.3.2.1. Secondary explosives are much less sensitive than primary

explosives.

C12.4.1.3.2.2. Soil containing 10 percent or more by weight of either any

secondary explosives or a mixture of secondary explosives presents an explosive hazard and
shall be treated as HD 1.1.

C12.4.1.3.2.3. Soil containing less than 10 percent by weight of any secondary

explosive or a mixture of secondary explosives does not present an explosive hazard.

C12.4.1.3.3. Nitroglycerin, Nitrocellulose, and Nitroguanidine

C12.4.1.3.3.1. Soil containing 10 percent or more by weight of nitroglycerin,

nitrocellulose, or nitroguanidine presents an explosive hazard and shall be treated as HD 1.1.

C12.4.1.3.3.2. Soil containing less than 10 percent by weight of nitroglycerin,

nitrocellulose, or nitroguanidine does not present an explosive hazard. (Care must be taken when
applying this threshold rule to less-permeable soils, such as clay, that may cause nitroglycerin to
pond, rather than be absorbed.)

C12.4.1.3.4. Other Energetic Materials Mixtures. The potential explosive hazard of

such mixtures in soil may be unknown and may require testing. If the hazard is unknown,
manage soil mixtures containing only propellants as secondary explosives, and all other soil
mixtures containing energetics (e.g., liquid propellants) as primary explosives.

C12.4.2. Real Property (Buildings and Installed Equipment). Military munitions operating
buildings (e.g., munitions production or demilitarization facilities) and any installed equipment
may contain residual explosives that present an explosive hazard. Of particular concern are
building features (e.g., floors, roofs, walls, drains, internal and external piping, ventilation
systems) in which explosives residues could present explosive hazards and industrial equipment,
particularly equipment with internal cavities from facilities used in munitions production or
demilitarization operations (e.g., cast loading or milling, steam-out) that generated explosives
residues (e.g., dust, vapors, liquids). To the extent such buildings or installed equipment is
believed to present an explosive or CA hazard, DoD Components must submit to the DDESB for
review and approval the explosives or CA safety provisions of any required plans for transfer or
use of such buildings and installed equipment before use or transfer for purposes incompatible
with the presence of the explosive hazard (see Chapter 16).

C12.4.3. Construction Support

C12.4.3.1. DoD Components should consider the level or construction support required,
based on site-specific data, during the below activities.

C12.4.3.1.1. Intrusive activities (e.g., building construction, laying utilities, or road

improvements) on property known or suspected to contain MEC or CA, regardless of CA
configuration, or on property on which residual explosive or CA hazards may exist.

248 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.4.3.1.2. The removal or remediation of debris or media in areas where there is a

probability of encountering MEC (e.g., former OB/OD grounds) or CA.

C12.4.3.2. The responsible authority (e.g., installation commander or designated

representative) will determine whether such support is required and the level of effort of required
support on a case-by-case basis (see subparagraph C12.5.7.). Construction support is determined
by the probability of encountering MEC or CA, regardless of CA configuration.

C12.4.3.2.1. Low Probability. “On-call” construction support is appropriate.

C12.4.3.2.1.1. A “low” determination may only be assigned to those areas for

which a search of available historical records and onsite investigation data indicates that, given
the military or munitions-related activities that occurred at the site, the likelihood of
encountering MEC or CA, regardless of CA configuration, is low.

C12.4.3.2.1.2. Munitions-related activities that may merit a “low” determination

include, but are not limited to, the former use of the area for live-fire training exclusively with
small arms ammunition; for maneuver training, to include maneuver training involving the use of
smokes, pyrotechnics, and simulators; as firing points; for munitions inspection, handling,
storage, or transfers, to include residue points and inert storage yards; for air defense; or as
munitions operating facilities. The exceptions are facilities in which the processes used might
have resulted in the generation of concentrations of munitions constituents high enough to
present an explosive hazard. Areas on which previous responses have been completed may also
qualify for “low” determinations.

C12.4.3.2.1.3. Immediate reassessment by the responsible authority of the level

of construction support required is appropriate upon the discovery of MEC or CA, regardless of
CA configuration.

C12.4.3.2.2. Moderate to High Probability. “Onsite” construction support should be

provided to remove explosive or CA hazards in the construction footprint, per a DDESB-
approved ESS or CSS, before intrusive construction or other intrusive activities occur. (NOTE:
When the depth of intrusive activities exceeds the detection limits of the detection equipment
used, soil should be removed in layers to allow detection and removal of MEC or CA, regardless
of CA configuration, in the construction footprint.)

C12.4.3.2.2.1. A “moderate to high” determination may be assigned to those

areas for which a search of available historical records or onsite investigation data indicates that,
given the military or munitions-related activities that occurred at the site, there is more than a
low probability that MEC or CA are present.

C12.4.3.2.2.2. Munitions-related activities that may merit a “moderate to high”

determination include, but are not limited to, the former use of the area for live-fire training other
than exclusively with small arms ammunition; as operational range impact areas; for OB or OD

249 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

of munitions; as munitions operating facilities where processes used might have resulted in the
generation of concentrations of munitions constituents high enough to present an explosive
hazard; for munitions burial; or for any activities involving CA.

C12.4.4. Anomaly Avoidance

C12.4.4.1. The use of anomaly avoidance techniques is appropriate on properties known

or suspected to contain UXO or other munitions (e.g., Discarded Military Munitions (DMM))
that may have experienced abnormal environments to allow the below activities in such areas
while avoiding surface explosive or CA hazards and, when necessary, subsurface anomalies.
Anomaly avoidance is used when:

C12.4.4.1.1. Surface MEC or CA, regardless of CA configuration, will be avoided

during any activities that require entry to the area (e.g., collections of environmental samples, the
conduct of cultural resource studies).

C12.4.4.1.2. Subsurface anomalies will be avoided during any intrusive work (e.g.,
drilling environmental monitoring wells).

C12.4.4.2. During anomaly avoidance:

C12.4.4.2.1. Escort support must be provided by EOD personnel, or:

C12.4.4.2.1.1. Within areas known or suspected to contain MEC, excluding CA,

regardless of configuration, by:

C12.4.4.2.1.1.1. UXO-qualified personnel.

C12.4.4.2.1.2.2. UXO Technician I personnel under the supervision of UXO-

qualified personnel. The responsible commander or authority may, based on a risk assessment
and implementation of methods to mitigate any potential exposures, approve UXO Technician I
personnel to perform escort duties without supervision.

C12.4.4.2.1.2. Within areas known or suspected to contain CA, regardless of

configuration, to include areas where such CA is commingled with other MEC, by UXO-
qualified personnel trained in CWM responses.

C12.4.4.2.2. Explosives safety requires that discovered surface MEC or CA,

regardless of CA configuration, be avoided and their location noted and reported to appropriate
authorities.

C12.4.4.2.3. Detected subsurface anomalies must not be investigated, but they shall
be marked, when appropriate, and avoided.

C12.4.5. Frost Heave. This phenomenon occurs when three conditions are met: (a) freezing
temperatures are present in the soil column; (b) the soil is frost susceptible; and (c) there is

250 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

sufficient moisture present in the soil to cause soil movement upon ice crystal formation. These
three factors will be evaluated to assess the likelihood of frost heave moving residual MEC or
CA, regardless of CA configuration, upward through the soil column. Where frost heave may
have such an effect, explosives safety requires procedures be implemented to monitor the
effectiveness of response actions for the affected area. (Other naturally occurring phenomena
(e.g., erosion, tidal changes) could necessitate similar monitoring.)

C12.4.6. Soil Containing CA

C12.4.6.1. The criteria below apply to soil known to be contaminated with one or more
of the following CA: mustard, L, GD, GA/GB, O-cyclohexyl Methylphosphono-fluoridate (GF)
(common name is cylcosarin), or VX. This criteria applies only if a headspace measurement is at
or above the Short Term Exposure Limits (STEL) (see subparagraph C12.4.6.4.1.) or a
laboratory extraction sample is at or above the Hazardous Waste Control Limit (HWCL) for
solid materials: mustard, L, GD, GA/GB, GF, or VX. Certain CA-related operations, such as
taking core samples at a suspect CWM or CA burial site, require laboratory extraction sampling.

C12.4.6.2. Soil for which no evidence exists of CA contamination does not require
treatment or remediation.

C12.4.6.3. An appendix to the site’s Site Safety and Health Plan that addresses the
procedures (e.g., personnel protection, monitoring, sampling, packaging, disposal) for the
handling and disposition of CA-contaminated soil is required for environmental responses to soil
known or suspected to be contaminated with CA.

C12.4.6.4. Air-sampling methods will be used to detect CA during CWM responses.

When soil contaminated with CA is encountered and an air concentration is at or above the
STEL based on off-gas monitoring of the headspace of a container or of air in the immediate area
of the operation, appropriate personnel protective measures shall be employed and the CA-
contaminated soil shall be decontaminated to below the HWCL levels of subparagraph
C12.4.6.4.2. unless the CA-contaminated soil may be shipped per DOT regulations and
approvals and a receiving Treatment Storage Disposal Facility (TSDF) is qualified to process the
CA-contaminated soil per Federal, State, interstate, and local laws and regulations. If air
monitoring is below the STEL, soil samples will be taken to determine if the soil exceeds the
HWCL.

C12.4.6.4.1. The STELs for air sampling CA contamination are:

C12.4.6.4.1.1. 0.003 milligrams per cubic meter (mg/m3) for mustard (H, HD, or
HT) agent.

C12.4.6.4.1.2. 0.003 mg/m3 for L.

C12.4.6.4.1.3. 0.0002 mg/m3 for GD/GF.

C12.4.6.4.1.4. 0.0001 mg/m3 for GA/GB.

251 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.4.6.4.1.5. 0.00001 mg/m3 for VX.

C12.4.6.4.2. When soil contaminated with CA is encountered at or above the HWCL

levels listed in Table C12.T1. as determined by laboratory extraction and analysis of soil
samples, the CA-contaminated soil shall be decontaminated to below the levels listed for the
HWCL, or to a level required by Federal, State, interstate, and local laws and regulations.

C12.4.6.5. Once decontaminated to the appropriate level, the CA-contaminated waste

must be packaged in a DoT-approved shipping container and shipped to an approved, licensed
treatment or disposal facility per Federal, State, and local laws and regulations. Records of
disposition must be maintained by the generator per Federal, State, interstate, and local laws and
regulations.

C12.4.6.6. Soil that is found to be below the HWCL, but above the levels of
subparagraph C12.4.6.7., shall be disposed of as hazardous waste per federal, state, interstate,
and local laws and regulations or treated by an approved, licensed treatment or disposal facility
to the levels of subparagraph C12.4.6.7.

C12.4.6.7. Soil that is at or below the Health-Based Environmental Screening Levels

(HBESL) for residential or industrial soil listed in Table C12.T2., as appropriate, may be used or
disposed of per federal, state, interstate, and local laws and regulations (e.g., returned to the hole
or disposed of as non-contaminated, non-hazardous material).

C12.5. REQUIRED SAFETY SUBMISSIONS (ESS, CSS AND EXPLOSIVES OR CWM

SITE PLANS)

C12.5.1. Explosives and CA safety requires:

C12.5.1.1. A DDESB-approved site plan, ESS, or CSS before the start of munitions
response activities (e.g., field activities) that involve the placement of explosives on a site; the
intentional physical contact with MEC or CA, regardless of CA configuration; or the conduct of
ground-disturbing or other intrusive activities in areas known or suspected to contain MEC or
CA, regardless of CA configuration; or

C12.5.1.2. A Service-level explosives safety office review and approval pending

DDESB review and approval of the submission, provided the submission is at the DDESB for
review and approval and the Service accepts that the DDESB approval may impose different or
additional munitions or CWM response requirements.

C12.5.2. A DDESB-approved ESS or CSS, or an explosives or CWM site plan, or a

combination thereof, is required for:

C12.5.2.1. MRS investigation or characterization (e.g., Engineering Evaluation/Cost

Analysis (EE/CA) or Remedial Investigation/Feasibility Study (RI/FS)) that involve the
intentional physical contact with MEC or CA, regardless of CA configuration (see subparagraph

response (see subparagraphs C12.5.8. and C12.5.9.)

C12.5.3. A DDESB-approved ESS or CSS, or an explosives or CWM site plan is not

required for:

C12.5.3.1. Munitions or explosives emergency responses.

C12.5.3.2. Preliminary assessments or site inspections (e.g., site visits in conjunction

with an archival search) when intentional physical contact with MEC or CA, regardless of CA
configuration, or the conduct of ground-disturbing or other intrusive activities are not intended
(see subparagraph C12.5.3.6.).

C12.5.3.3. Clearance activities on operational ranges. (Addressing military munitions

burial sites on operational ranges is not a clearance activity.)

253 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.3.4. Munitions responses on former ranges used exclusively for training with
small arms ammunition.

C12.5.3.5. On-call construction support.

C12.5.3.6. Anomaly avoidance activities.

C12.5.4. MRS Investigation or Characterization. An explosives or, when appropriate, a

CWM site plan is required for MRS investigations or characterizations that involve intentional
physical contact with MEC or CA, regardless of CA configuration. Such site plans will address
areas (e.g., magazines) used for the storage of commercial or military demolition explosives,
MEC or CA, regardless of CA configuration; planned or established demolition or disposal
areas; and the MRA, MRS, or response area boundaries. (See subparagraph C12.5.8.3.7.) MRS
investigation and characterization are used to collect the information needed to design the
required munitions response and to prepare, as appropriate, an ESS or CSS for the selected
response.

C12.5.5. NDAI or NOFA ESS or CSS. When a NDAI or NOFA decision is made for an
MRA or MRS or for a response area, an ESS or CSS must, at a minimum, provide:

C12.5.5.1. The site identification (e.g., name, unique identifier).

C12.5.5.2. The site location.

C12.5.5.3. Justification for the decision.

C12.5.6. TCRA ESS or CSS. To expedite the approval process, DoD Components are
encouraged to submit TCRA ESS or CSS electronically through their chain of command to the
DDESB. A TCRA ESS or CSS must, at a minimum, identify or provide:

C12.5.6.1. The site identification (e.g., name, unique identifier).

configuration, is considered moderately or highly probable. This submission must provide the
information outlined in paragraphs C12.5.8. and C12.5.9., as appropriate. The information may
be tailored based on site-specific conditions.

C12.5.8. Selected Munitions Response ESS. The below information is required in an ESS
for the execution of the selected munitions response to address MEC. When CA, regardless of
configuration, is known or suspected to be present along with explosive hazards, or when it is
explosively configured, a submission that provides both explosives safety (as outlined in this
section) and CA safety information (see paragraph C12.5.9.) is required.

C12.5.8.1. Background. The ESS must provide, for informational purposes, a brief
description of the reasons for the munitions response. The ESS must identify or provide:

C12.5.8.1.1. The scope of munitions response activities.

C12.5.8.1.2. Any significant differences in munitions response activities that will

occur within the MRA or MRS. (NOTE: The ESS must identify significant differences in the
current, determined, or reasonably anticipated future land use of different sections of the
property, significant differences in the types or conditions of MEC expected to be encountered,
and any sections of the MRA that will not require munitions response activities.)

C12.5.8.2. Maps. The following maps and related information must be furnished:

C12.5.8.2.1. Regional Map. A map depicting the regional location of the MRA or
MRS (e.g., a state or boundary illustration map with the MRA indicated on it).

255 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.8.2.2. MRA or MRS Maps. Maps of the area or areas at which the munitions
response is planned. These maps and related information shall indicate:

C12.5.8.2.2.1. Areas that:

C12.5.8.2.2.1.1. Contain or are suspected of containing MEC that the ESS

addresses.

C12.5.8.2.2.1.2. Were suspected of containing MEC, but that research or site

characterizations have subsequently shown do not contain such.

C12.5.8.2.2.1.3. The ESS does not address, but that either a previous safety
submission addressed or a future safety submission will address.

C12.5.8.2.2.2. The current, determined, or reasonably anticipated future land use

of property within the MRA or MRS that is known or suspected to contain MEC that the ESS
addresses.

C12.5.8.2.2.3. The ownership and land use of adjacent properties, as appropriate.

C12.5.8.2.2.4. Any other situation that may influence or require consideration

during the response (e.g., flight corridors, traffic routes).

C12.5.8.3. ESQD

C12.5.8.3.1. The planned locations for MEC response-related operations must be

shown on ESQD maps. (NOTE: Preliminary site work, such as surveying, laying search lanes,
and detecting anomalies does not require establishment of an ESQD arc.)

C12.5.8.3.2. ESQD arcs for both intentional and unintentional detonations must be
established and shown on ESQD maps for each MRS.

C12.5.8.3.2.1. The Minimum Separation Distance (MSD) for unintentional

detonations, which may be reduced by employing the engineering controls listed in Reference (j)
or other DDESB-approved engineering controls, for:

C12.5.8.3.2.1.1. Nonessential personnel is the greatest distance of:

C12.5.8.3.2.1.1.1. Blast overpressure, as computed by using the

formula: D = 40W1/3 [D=15.87Q1/3].

C12.5.8.3.2.1.1.2. The calculated HFD as provided in Reference (p).

C12.5.8.3.2.1.2. Team Separation Distance (TSD) is based on blast

overpressure, as computed by the formula: D = 40W1/3 [D=15.87Q1/3].

256 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.8.3.2.2. The MSD for intentional detonations (see Chapter 9), which may
be reduced by employing the engineering controls listed in Reference (j) or other DDESB-
approved engineering controls, is the greatest distance of:

C12.5.8.3.2.2.1. Blast overpressure, as computed by using the

formula: D = 328W1/3 [D=130.16Q1/3].

C12.5.8.3.2.2.2. The calculated MFD, as provided in Reference (p).

C12.5.8.3.3. MEC, Excluding CA-filled Munitions, Hazard Classification, and

Storage

C12.5.8.3.3.1. Recovered MEC, other than Recovered CWM (RCWM), shall be

managed as HD 1.1, unless assigned differently by an Interim Hazard Classification (IHC)
authority, and assigned an appropriate CG. When storage at the MRA or MRS is necessary,
recovered MEC must be stored separately from serviceable munitions and from any RCWM.
(NOTE: For RCWM, see subparagraph C12.5.9.6.)

C12.5.8.3.3.2. Nonessential personnel in structures shall be afforded protection

equivalent to IBD from storage locations. Nonessential personnel in the open shall be afforded
protection equivalent to PTRD from storage locations. (See Chapter 9.) There is no required
ESQD protection for essential personnel from locations they are using for storage.

C12.5.8.3.3.3. The IMD, based on the NEWQD of the munition with the greatest
NEWQD that is reasonably expected to be encountered, applies from intrusive operations to
storage sites to prevent propagation to a storage location in event of an accidental explosion
during intrusive operations. For distances less than IMD, DDESB-approved engineering
controls must be used during intrusive operations.

C12.5.8.3.4. Planned or Established Demolition Areas. A planned or established

demolition area is an area used repetitively to destroy munitions during a munitions response.
(Such areas may be an existing OD area or a new area planned for intentional detonation.) An
ESQD arc must be provided around demolition areas. The size of the ESQD arc will be based on
requirements of this Standard (see Chapter 9).

C12.5.8.3.5. Mechanized MEC, Excluding CA-filled Munitions, Processing

Operations. Examples of such processing operations include, but are not limited to: power
screening equipment, power rakes, and shredders.

C12.5.8.3.5.1. Nonessential Personnel. Nonessential personnel shall be provided

protection for intentional detonations (see subparagraph C12.5.8.3.2.2.) based on the MGFD.

C12.5.8.3.5.2. Essential Personnel. Essential personnel shall, when appropriate:

257 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.8.3.5.2.1. Be protected by shields or barricades designed to defeat

hazardous fragments from the MGFD.

C12.5.8.3.5.2.2. Be separated from the operation by K24 based on the

munition with the greatest NEWQD that is reasonably expected to be encountered. (NOTE:
DDESB-approved overpressure-mitigating engineering controls may be used to provide an
equivalent level of protection (2.3 psi) [15.9 kPa]).

C12.5.8.3.6. Intentional Burning of Buildings Contaminated with Explosives

Residues that Present an Explosive Hazard. All personnel shall be separated by K328
overpressure distance based on the MCE for the building, but not less than 1,250 feet.

C12.5.8.3.7. ESQD Maps. (NOTE: The ESQD arcs and the MRA and MRS
boundaries may be shown on the same map provided all PES and ES are shown in sufficient
detail.)

C12.5.8.3.7.1. ESQD-maps should be to scale and legible per subparagraph

C5.4.4.3.2.

C12.5.8.3.7.2. When a map does not contain a scale, all distances must be
labeled.

C12.5.8.3.7.3. The ESQD map shall show the following:

C12.5.8.3.7.3.1. Each MRA or MRS.

C12.5.8.3.7.3.2. The storage locations for demolition explosives and for

recovered MEC.

C12.5.8.3.7.3.3. Locations (planned or established) for the intentional

detonations or burning of MEC, excluding CA-filled munitions. Such locations include areas
where contained detonation technology will be used.

C12.5.8.3.7.3.4. All ES and PES and their relationships. (NOTE: Describe

any protective measures (e.g., evacuation of inhabited buildings, blocking off public highways)
that will be used to eliminate or minimize any exposures within the established exclusion zone.)

C12.5.8.3.7.3.5. All controlling ESQD arcs.

C12.5.8.3.7.4. ESQD Arcs. ESQD arcs must be shown for:

C12.5.8.3.7.4.1. Munitions. The MGFD shall be used for ESQD purposes for
any particular MRA or MRS. However, if a munition with a greater fragmentation distance is
encountered during the conduct of a munitions response, the ESQD arcs must be adjusted and the
ESS or explosives safety site plan must be amended.

258 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.8.3.7.4.2. Explosive Soil. To determine the ESQD arc for explosive

soil, calculate the MCE by multiplying the weight of the mix by the concentration of explosives
(e.g., 1,000 lb [453.60 kg] of soil containing 15 percent TNT has an MCE of 150 lb [68 kg]).
When concentrations vary within the site, weighted averages or other valid mathematical
technique can be used to determine the exclusion zone; however, the ESS must support their use.
The MSD for nonessential personnel shall be the greater of IBD for overpressure or the soil
ejecta radius per the Buried Explosion Module (BEM) contained in Reference (p) or other
DDESB-approved procedures (see Reference (j)).

C12.5.8.3.7.4.3. Real Property (Buildings and Installed Equipment). For real

property that is known or suspected to be contaminated with explosives residues that present an
explosive hazard, and that is slated for cleanup or dismantlement, the MCE will be estimated on
a case-by-case basis. The ESS shall include the rationale used for the estimation.

C12.5.8.3.8. Soil Sampling Maps. When the property involves concentrations of

explosives in the soil that are high enough to present an explosive hazard (see subparagraph
C12.4.1.):

C12.5.8.3.8.1. Provide a map that indicates areas that were determined to contain
explosive soil.

C12.5.8.3.8.2. Address methods (e.g., blending, bio-remediation) to be used to

reduce explosives concentrations to a non-reactive level.

C12.5.8.3.8.3. Address methods (e.g., wetting the soil before blending) to be used
to reduce any explosive hazards.

C12.5.8.4. Types of MEC. Based on research or data generated from characterization of

the MRA or MRS, provide the types of MEC expected to be encountered during munitions
response activities.

C12.5.8.5. Start Date. Provide the expected date that munitions response activities that
involve the placement of explosives on a site, the intentional physical contact with MEC, or the
conduct of ground-disturbing or intrusive activities in areas known or suspected to contain MEC
are scheduled to start. Indicate the potential consequence, if any, if DDESB approval does not
occur by the start date. (Site preparation activities (e.g., surveying, gridding, or locating
anomalies) may be conducted while awaiting DDESB approval of an ESS.)

C12.5.8.6. MEC Migration. Describe naturally occurring phenomena (e.g., drought,

flooding, erosion, frost heave, tidal changes) that could cause the migration or exposure of MEC,
and procedures for monitoring and managing such.

C12.5.8.7. Detection Equipment and Response Techniques. The intent of this section is
to describe the capabilities of detection equipment relative to the degree of removal required to
support the current, determined, or reasonably anticipated end use.

259 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.8.7.1. Describe the techniques to be used to detect and remove MEC.

C12.5.8.7.2. Identify the types of detection equipment to be used and the areas in
which they will be employed.

C12.5.8.7.3. Summarize methods used (e.g., test plots) to establish the expected
detection capabilities of the equipment used. If anomaly discrimination will be used, explain
what methods will be used to establish the expected accuracy of the discrimination.

C12.5.8.7.4. When describing the detection methods:

C12.5.8.7.4.1. Describe the rationale (e.g., best available technology based on

geology, topography, munitions characteristics, resource requirements) used to select the
detection methods and technologies to be used during the response.

C12.5.8.7.4.2. Address any limitations (e.g., equipment, terrain, soil type) and
mitigating actions, if any.

C12.5.8.7.4.3. Describe quality assurance and quality control (QA/QC) standards

and pass or fail criteria for QA/QC control audits.

C12.5.8.8. Disposition Techniques

C12.5.8.8.1. MEC, Excluding CA-Filled Munitions

C12.5.8.8.1.1. Briefly, describe the MEC, excluding CA-filled munitions,

disposition techniques (e.g., OB, OD, contained detonation, incineration) to be used.

C12.5.8.8.1.2. When recovered MEC, excluding CA-filled munitions, cannot be

destroyed within the MRA or MRS, address how explosives safety requirements will be met
during transportation and during offsite storage, treatment, or disposal. (NOTE: Disposition
actions should consider requirements applicable to waste military munitions.)

C12.5.8.8.2. Material Potentially Presenting an Explosive Hazard (MPPEH).

Describe the process to be used to manage MPPEH (see Chapter 16).

C12.5.8.9. Environmental, Ecological, Cultural and Other Considerations. Address any

environmental, ecological (e.g., endangered species), cultural (e.g., tribal spiritual or gathering
sites) and other factors that impacted, from an explosives safety perspective, the selection of the
munitions response.

C12.5.8.10. Technical Support. Summarize EOD, U.S. Army Forces Command/20th

Support Command/22nd Chemical Battalion, or UXO-technician or UXO-qualified personnel

22nd Chemical Battalion is manned with specially trained personnel that provide verification,

260 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

sampling, detection, mitigation, render safe, decontamination, packaging, escort, and remediation
of chemical, biological and industrial devices or hazardous materials.)

C12.5.8.11. Residual Risk Management. Address:

C12.5.8.11.1. LUC. The ESS must summarize any LUC to be implemented and
maintained on the property.

C12.5.8.11.2. Long-Term Management. The ESS must address how any potential
residual risks will be managed.

C12.5.8.12. Safety Education Program. Address methods to be used to educate the

public on the risks associated with MEC and CA, regardless of CA configuration.

C12.5.8.13. Stakeholder Involvement. Briefly, summarize how stakeholder concerns

affecting the explosives safety aspects of the selected munitions response were addressed.

C12.5.8.14. Contingencies. To reduce the need to submit amendments (see

subparagraph C12.6.1.), an ESS may describe alternative actions that could be used to address
contingencies. As an example, an ESS may list alternative DDESB-approved engineering
controls (see Reference (j)) that may be used under specified conditions.

C12.5.8.15. Unexpected CA Discoveries. Should CA, regardless of its configuration, be

discovered during munitions responses to MEC, excluding CA-filled munitions, all onsite
activities shall be halted until the need for a CWM response is evaluated and a decision is
approved by the Service-level explosives safety office. If it is decided that a CWM response is
necessary, response actions that involve the intentional physical contact with CA, regardless of
configuration, or the conduct of ground-disturbing or other intrusive activities in areas known or
suspected to contain CA shall not begin until the required CSS or CWM site plan is approved by
the DDESB.

C12.5.9. Selected CWM Response CSS and CWM Site Plans

C12.5.9.1. General

C12.5.9.1.1. A response in an area (e.g., a munitions response in an MRA or MRS)

that is known or suspected to contain CA, regardless of configuration, must include a CWM site
plan for an Interim Holding Facility (IHF) and, when the use of onsite destruction technology is
planned, for the site at which those destruction activities will occur. Generally, the information
required in a CSS parallels that for an ESS (see subparagraph C12.5.8.); however, such
information will be tailored to address CWM.

C12.5.9.1.2. A CSS is not required for certain activities on a site with a history of
CA-related activities when an installation or district commander, or a command-designated
representative, has approved a probability assessment finding for such activities stating that the
probability of discovering CA is expected to be “seldom” or “unlikely.” However, the site safety

261 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

and health plan must include contingency plans providing for the safe and expeditious
evacuation of the site in the event CA is discovered. Should CA, regardless of configuration, be
discovered during these activities, all onsite activities shall be halted until the need for a CWM
response is evaluated and a decision is approved by the Service-level explosives safety office. If
it is decided that a CWM response is necessary, response actions that involve the intentional
physical contact with CA, regardless of configuration, and/or the conduct of ground-disturbing or
other intrusive activities in areas known or suspected to contain CA shall not begin until the
required CSS or CWM site plan is approved by the DDESB.

C12.5.9.2. Explosives Hazards. When explosives hazards are known or suspected to

exist along with CA hazards within a response area (e.g., the MRA or MRS), a submission that
addresses both explosives safety (see subparagraph C12.5.8.) and CA safety (as outlined in this
section) is required.

C12.5.9.3. Background. (See subparagraph C12.5.8.1.)

C12.5.9.4. Maps. The maps provided with a CSS must meet the requirements of
subparagraph C12.5.8.2. In addition, the One Percent Lethality Distance and the IBD shall be
shown.

C12.5.9.5. Chemical Agent Hazards. When CA hazards are known or suspected to exist
within a response area (e.g., the MRA or MRS), the CA downwind hazard must be considered
when determining the MSD. The CSS shall provide the following information:

C12.5.9.5.1. A description of the CA MCE.

C12.5.9.5.2. A description of how essential and nonessential personnel and the

public will be protected should the CA MCE occur (see Chapter 11 for basic personnel
protection requirements (e.g., hazard zones and protective equipment) for operations involving
CWM). If an Engineering Control (EC), which has not been DDESB-approved, is to be used to
provide such protection, the CSS must include the technical data substantiating the new
engineering control’s effectiveness. EC may be used for:

C12.5.9.5.2.1. Protection from overpressure and fragments when explosively

configured CWM are known or suspected.

C12.5.9.5.2.2. Protection from CA effects (prevent vapor releases to the

environment) during both response activities and when RCWM is stored in the IHF.

C12.5.9.6. RCWM Hazard Classification and Storage

C12.5.9.6.1. RCWM, suspected or confirmed, regardless of its configuration, must

be stored separately from serviceable munitions and from other MEC. Additionally, suspect
RCWM shall be stored separately from all other munitions and from RCWM.

262 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.9.6.2. Suspect and known RCWM shall be managed as HD 1.1 until stowed in
an approved overpack container or until determined not to be RCWM (see subparagraph
C12.5.8.3.3) or to be non-explosively configured RCWM (see subparagraph C12.5.9.6.4.).
(NOTE: The CA downwind hazard must be considered, with the greater of the two distances
used for siting purposes.)

C12.5.9.6.3. Explosively-configured RCWM in an approved overpack container shall

be managed as HD 1.2.1 with an explosive MCE of one round or HD 1.2.2, based on its
NEWQD. Such storage may be considered HD 1.1 if advantageous for computing HFD using
DDESB-approved procedures (see Reference (p)). (The CA downwind hazard must be
considered, with the longer of the two distances used for siting purposes.)

C12.5.9.6.4. Non-explosively configured RCWM shall be managed as HD 6.1. (The

CA downwind hazard must be used for siting purposes.)

C12.5.9.7. CWM Site Plan. A DDESB-approved CWM Site Plan for an IHF is required
when CA, regardless of configuration, is known or suspected to exist on a response area. The
IHF Site Plan, which is based on the worst-case CA configuration expected to be encountered, is
included in the CSS. The IHF site plan shall:

C12.5.9.7.1. Identify the public access exclusion distance (PAED).

C12.5.9.7.2. Identify all associated ESQD arcs (see subparagraph C12.5.8.3.).

C12.5.9.7.3. Address the evacuation procedures for personnel within the PAED.

C12.5.9.7.4. Address any security measures and access controls for the IHF.

C12.5.9.7.5. Address any EC that will be used to mitigate a CA release during IHF
activities, such as:

C12.5.9.7.5.1. Static storage within the IHF.

C12.5.9.7.5.2. RCWM assessment activities (e.g., X-ray, portable isotopic

neutron spectroscopy (PINS)).

C12.5.9.7.5.3. Transportation preparation activities (e.g., transloading of multiple

round containers (MRCs), MRC movement into or out of the IHF).

C12.5.9.7.6. Address soil sampling maps. (See subparagraph C12.5.8.3.8.).

C12.5.9.7.7. Address types of CA. (See subparagraph C12.5.8.4.).

C12.5.9.7.8. Address start date. (See subparagraph C12.5.8.5.).

263 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.5.9.8. Detection Equipment and Response Techniques. (See subparagraph

C12.5.8.7.)

C12.5.9.9. Disposition Techniques

C12.5.9.9.1. CA, Regardless of Configuration

C12.5.9.9.1.1. Briefly, describe the disposition techniques (e.g., onsite

destruction) to be used.

C12.5.9.9.1.2. When RCWM cannot be destroyed on site, address how CA safety

and, if applicable, explosives safety requirements, will be met during transportation and during
offsite storage, treatment or disposal. (Disposition actions should consider guidance applicable
to waste military munitions.)

C12.5.9.9.2. MPPEH. Describe the process to be used to manage MPPEH. (See

Chapter 16.)

C12.5.9.10. Environmental, Ecological, Cultural, and Other Considerations. (See

subparagraph C12.5.8.9.).

C12.5.9.11. Technical Support. (See subparagraph C12.5.8.10.).

C12.5.9.12. Residual Risk Management. (See subparagraph C12.5.8.11.) .

C12.5.9.13. Safety Education Program. (See subparagraph C12.5.8.12.).

C12.5.9.14. Contingencies. (See subparagraph C12.5.8.14.).

C12.5.9.15. Unexpected MEC or Explosively Configured CWM Discoveries. Should

unexpected MEC or explosively configured CWM be discovered during a CWM response, all
onsite activities that involve intentional physical contact with such MEC or explosively
configured CWM, or the conduct of ground-disturbing or other intrusive activities in areas
known or suspected to contain such MEC or explosively configured CWM, shall be halted until
the newly identified explosive hazards are evaluated and the DDESB approves all required CSS
amendments or explosives site plans.

C12.6. AMENDMENTS AND CORRECTIONS

An amendment or correction to an approved ESS or CSS does not require the resubmission of
the complete ESS or CSS package. However, the information submitted must be in sufficient
detail to identify the specific ESS or CSS being amended or corrected, the affected portions, and
the precise amendments or corrections.

264 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.6.1. Amendments. Amendments are only required when a change to an approved ESS
or CSS increases explosives safety or CA risks, identifies requirements for additional or
increased explosive or CA hazard controls, or increases or decreases an ESQD arc.

C12.6.1.1. An amendment requires DDESB approval before the affected response

actions can continue. However, response actions need not be stopped pending such approval
provided:

C12.6.1.1.1. The amendment pertains to an area (e.g., MRA or MRS) for which an
ESS or CSS has already been approved; and,

C12.6.1.1.2. The DoD Component:

C12.6.1.1.2.1. Institutes protective measures (e.g., increased ESQD, use of

DDESB-approved EC) to address any explosive or CA hazards.

C12.6.1.1.2.2. Accepts the possibility that the DDESB approval process may
impose different or additional explosives safety or CA safety requirements.

C12.6.1.2. If the amendment is for a new response area (e.g., a new MRS), then the
DDESB must approve the amendment before intrusive activities begin in the new response area.

C12.6.1.3. To allow the response to continue with minimal interruption, amendments

should be processed by electronic means.

C12.6.1.4. Changes that require an amendment include:

C12.6.1.4.1. Constraints in funding, technology, access, and other site-specific

conditions that impact the degree of removal addressed in the approved ESS or CSS.

C12.6.1.4.2. Any increase or decrease of the ESQD arcs.

C12.6.1.4.3. A change in operations requiring explosives siting or re-siting of an IHF

for CWM.

C12.6.1.4.4. Changes in LUC or long-term management to address residual risks.

Such changes would not require intrusive activities to stop while the amendment is being
processed.

C12.6.2. Corrections. Corrections address changes to an approved ESS or CSS that do not
increase explosives safety or CA risks or exposures. Corrections:

C12.6.2.1. Do not require approval.

C12.6.2.2. Are primarily administrative in nature and provided for information purposes.

265 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.7. AAR

C12.7.1. An AAR for completed munitions or CWM responses is a required feature of all
DDESB-approved ESS or CSS. The AAR’s purpose is to document that the explosives and
chemical safety aspects of the selected response have been completed per the approved ESS or
CSS. In most cases, a “Statement of MEC Removal” or “Statement of Munitions Response
MEC Removal Actions” fulfills the requirements in subparagraph C12.7.5. The DDESB Staff
shall acknowledge receipt of an AAR, and raise any issues that require resolution before land
transfer or an alternative use can safely proceed.

C12.7.2. The AAR:

C12.7.2.1. Shall be submitted to the DDESB through the responsible DoD Component.

C12.7.2.2. May be submitted electronically.

C12.7.2.3. Will remain part of the DDESB’s action file; however, DoD Components
continue to be responsible for complying with all recordkeeping requirements.

C12.7.2.4. Shall summarize the MEC or CA, regardless of CA configuration, found.

C12.7.2.5. Shall describe the relative effectiveness and any limitations of the
technologies used during the munitions response or CWM response and the effects on residual
risk relative to that originally projected.

C12.7.2.6. Shall include maps showing:

C12.7.2.6.1. Areas from which MEC or CA, regardless of CA configuration, was

removed.

C12.7.2.6.2. Areas within a response area (e.g., within a MRA or MRS) where
response actions were not performed and the rationale for not addressing those areas.

C12.7.2.6.3. The known or reasonably anticipated end use of each area.

C12.7.2.7. Shall summarize the LUC that were implemented, if any, and the areas to
which they apply.

C12.7.2.8. Shall address provisions for long-term management.

C12.8. TRANSFER OF REAL PROPERTY OUTSIDE OF DoD CONTROL

Pursuant to DoD guidance on real property disposal, real property known to contain or suspected
of containing explosive or CA hazards may not be transferred out of DoD control (other than to

266 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

the Coast Guard) until the Chairman, DDESB, has approved measures submitted by the
transferring Component to ensure the recipient of the property is fully informed of both the
actual and potential hazards relating to the presence or possible presence of explosives or CA,
and restrictions or conditions placed on the use of the property to avoid harm to users due to the
presence of explosives or CA.

C12.8.1. Notices. A recipient of such DoD property shall be provided:

C12.8.1.1. Details of any past removal or remedial actions, including:

C12.8.1.1.1. The degree of MEC or CA removal.

C12.8.1.1.2. The process used to determine that degree of removal to be adequately

protective.

C12.8.1.2. Written notification that detection and removal methods are not 100 percent
effective, and that residual hazards may remain in areas (e.g., MRS) that were subjected to
response actions.

C12.8.2. Restrictions and Conditions. Based on potential explosive and CA hazards present
and the projected use of the property, the following types of use restrictions and conditions shall
be imposed, as appropriate, on such DoD property:

C12.8.2.1. A prohibition on excavation or drilling in any areas known or suspected to

contain MEC or CA, regardless of CA configuration, without appropriate permits or assistance.

C12.8.2.2. A prohibition on disturbing, removing, or destroying any found MEC or CA,

regardless of CA configuration.

C12.8.2.3. A requirement to immediately notify local law enforcement representatives of

any discovery of MEC or CA, regardless of configuration.

C12.8.2.4. A prohibition on the construction or installation of particular improvements

including utilities, roadways, airstrips, navigable waterways, pipelines, and structures, both
above and below ground.

C12.8.2.5. A prohibition on specific alterations, extensions, or expansions to such

improvements.

C12.8.2.6. A prohibition on certain types of uses, such as child care centers, housing, or
farming.

C12.8.2.7. A restriction to a specific type of use or owner, such as a state National Guard
range.

267 CHAPTER 12
DoD 6055.09-STD, February 29, 2008

C12.8.2.8. Inclusion of DoD Component explosives and CA safety personnel and the
Chairman, DDESB, in deliberations, decision making, and approvals pertaining to future
munitions response activities to address MEC or CA, regardless of CA configuration.

C12.8.2.9. Inclusion of the restrictions and conditions in the recorded land records for
the jurisdiction, to the extent allowed by state law.

268 CHAPTER 12

C14. CHAPTER 14
SPECIAL STORAGE PROCEDURES FOR WASTE MILITARY MUNITIONS

C14.1. SCOPE AND APPLICABILITY

C14.1.1. The Environmental Protection Agency (EPA) promulgated the Munitions Rule
(MR), Subpart M of Part 266, title 40, CFR (Reference (al)) to define when chemical and
conventional military munitions become a solid or hazardous waste and to provide for the safe
storage and transportation of such waste. The MR takes precedence over these Standards. The
MR sets forth two approaches for the storage of waste military munitions:

C14.1.1.1. A Conditional Exemption (CE) from certain “Resource Conservation and

Recovery Act (RCRA)” (Reference (am)) requirements.

C14.1.1.2. A new RCRA storage unit standard (i.e., Subpart EE of Parts 264 and 265 of
40 CFR (Reference (an))).

C14.1.2. This chapter establishes additional requirements for storage of waste military
munitions in the U.S.

C14.2. WAIVERS AND EXEMPTIONS

C14.2.1. CE Storage. Waivers and exemptions from this Standard are not authorized for AE
storage facilities (hereafter designated as an ASU) storing CE waste military munitions.

C14.2.2. RCRA Storage. Waivers and exemptions from this Standard shall only be available
to DoD Components storing waste munitions under RCRA unit standards (e.g., Subpart EE of
Part 264 of 40 CFR (Reference (an))). The approval authority for these waivers and exemptions
is the Secretary of the Military Department, who may delegate the authority no lower than an
assistant secretary.

C14.3. REQUIREMENTS FOR STORAGE OF WASTE MILITARY MUNITIONS

UNDER CE

C14.3.1. The DoD Components shall ensure that waste military munitions stored under CE
comply with 40 CFR 266.205(a) (Reference (an)). (The MR-established CE does not apply to
toxic chemical agents or toxic chemical munitions.)

C14.3.2. The DoD Components shall ensure that installations and responsible activities:

C14.3.2.1. Maintain records of stored waste military munitions for a minimum of 3 years
from the date they were last stored. The records must be distinguished by type. A separate
record or line item is required for each type of munition in any mixed lot of munitions received
for storage. The record shall include the following:

274 CHAPTER 14
DoD 6055.09-STD, February 29, 2008

C14.3.2.1.1. The type of waste military munitions stored by standard nomenclature,

Lot Number, FSC, National Stock Number (NSN), DoDAC, and condition code.

C14.3.2.1.2. The quantity stored.

C14.3.2.1.3. The date identified as “waste.”

C14.3.2.1.4. The date they left storage.

C14.3.2.1.5. The storage location or locations (e.g., building number or storage pad,
and grid coordinates) where they were stored.

C14.3.2.1.6. The means (e.g., destroyed, demilitarized, and shipped) and date of
disposition.

C14.3.2.1.7. When applicable, the sending and receiving sites for those waste
military munitions received from or shipped to offsite sources.

C14.3.2.2. Physically separate (e.g., on a separate pallet or shelf) waste military

munitions from non-waste military munitions when both are stored in the same ASU.

C14.3.2.3. Clearly mark the physically separated waste military munitions to ensure
proper identification.

C14.3.2.4. Store waste military munitions under CE in ASU that comply (without waiver
or exemption) with the provisions of this Standard. Each ASU storing waste military munitions
or explosives under CE must be included in a DDESB-approved explosives safety site plan that
the installation keeps on file. Those portions of the site plan addressing ASU storing waste
military munitions under CE shall be made available to applicable Federal or State
environmental regulatory authorities on request.

C14.3.2.5. Have SOP or plans (see section C8.6.) that provide safety, security, and
environmental protection. Those plans shall be coordinated with the applicable Federal, State,
and local emergency response authorities (e.g., law enforcement, fire departments, and hospitals;
etc.) and any established LEPC.

C14.3.3. Loss of CE.

C14.3.3.1. The un-permitted or uncontrolled detonation, release, discharge, or migration

(e.g., loss or theft, or as a result of fire or explosion) of waste military munitions out of any ASU
that might endanger human health or the environment shall result in the immediate loss of CE for
those waste military munitions. Incidents of that nature and the loss of CE require reporting
under section C14.5.

275 CHAPTER 14
DoD 6055.09-STD, February 29, 2008

C14.3.3.2. The applicable Federal or State environmental regulatory authorities may

withdraw CE based on review or inspection of the installation’s or responsible activity’s
compliance with the requirements for storage of waste military munitions under CE. The DoD
Components may, at any time, restrict an activity from using CE. Additionally, the DDESB or
the DoD Component, upon discovery of a condition that could warrant loss of CE, shall report
the condition to the applicable DoD Component and to the commander of the installation or
responsible activity.

C14.3.3.3. If CE is lost, the waste military munitions are subject to other RCRA
hazardous waste regulations. The installation or responsible activity must obtain any required
RCRA permits because of the loss of CE.

C14.3.3.4. Installations and responsible activities may apply for reinstatement of CE

under 40 CFR 266.205(c) (Reference (an)).

C14.4. OTHER STORAGE STANDARDS

C14.4.1. The DoD Components shall forward to the Chairman, DDESB, a copy of their
implementing standards or regulations pertaining to the storage of waste military munitions.

C14.4.2. Many States regulate waste management activities, including the storage of waste
military munitions. Their authority is based on the waiver of sovereign immunity in federal
environmental laws. Their laws, to the extent they fall within the waivers of sovereign
immunity, take precedence over these Standards. If such State regulations conflict with DDESB
or DoD Components’ explosives safety standards, the affected Component shall attempt to
resolve the conflict. For those issues that cannot be resolved, the DoD Component shall notify
the Chairman, DDESB, through its Board Member if it has one, of any irreconcilable conflict of
State law, regulation, or directive with these or other DoD or Military Component explosives
safety standards.

C14.5. UN-PERMITTED AND UNCONTROLLED LOSS REPORTING

In addition to other applicable reporting requirements, installations and responsible activities

shall notify their chain of command, the DDESB Chairman (through the DoD Component
channels), the applicable Federal or State environmental regulatory authority, and established
local committees, as follows:

C14.5.1. Telephonically or, in the case of the DoD Component and the DDESB,
electronically (by e-mail message or facsimile and using the format specified in Chapter 13)
within 24 hours from the time the installation or responsible activity becomes aware of any un-
permitted or uncontrolled detonation, release, discharge, or migration of waste military
munitions out of any ASU (e.g., loss or theft, or as a result of fire or explosion) that may
endanger human health or the environment; and

276 CHAPTER 14
DoD 6055.09-STD, February 29, 2008

C14.5.2. In writing, if the initial report was telephonic, within 5 days from the time the
installation or responsible activity becomes aware of any un-permitted or uncontrolled
detonation, release, discharge, or migration of waste military munitions out of any ASU (e.g.,
loss or theft, or as a result of fire or explosion) that may endanger human health or the
environment. Follow-up reports to the DoD Component and the DDESB are required only when
pertinent information, which was not previously reported, becomes known. Such reports, to
include a report of investigation, shall comply with the requirements of Chapter 13.

C14.6. CLOSURE OF FACILITIES STORING WASTE MILITARY MUNITIONS

UNDER CE

C14.6.1. In addition to the explosives safety requirements of section C1.4.:

C14.6.1.1. When an ASU that stored waste military munitions under CE is permanently
taken out of service for the storage of non-waste and waste military munitions, installations and
responsible activities shall ensure that such ASU are closed in accordance with applicable
requirements.

C14.6.1.2. Installations or responsible activities must notify the cognizant Federal or

State environmental regulatory authorities in writing at least 45 days before the closure activities
begin, or as provided by applicable law. Initiation of those closure procedures should occur
within 180 days, or as provided by applicable law, after the date the decision is made to
permanently stop using the ASU for the storage of military munitions.

C14.6.1.3. On completion of closure activities, a “Certification of Closure,” signed by

the installation or responsible activity commander, or other equivalent level authority, and by an
independent (i.e., an individual not assigned within the commander’s or equivalent-level
authority’s chain of command) registered professional engineer must be submitted to the
cognizant Federal or State environmental regulatory authorities within 90 days of completing the
closure activities, or as provided by applicable law.

C14.6.1.4. The Certificate of Closure must state, at a minimum, that each of the
explosives safety requirements in section C1.4. have been met and that waste military munitions
and residues are removed in such a manner as to protect the public and the environment
consistent with the planned use of the ASU and of the property.

C14.6.1.5. If closure certification cannot be rendered, the installation or responsible

activity must contact the cognizant Federal or State environmental regulatory authorities to
determine the required course of action.

C14.6.2. Discontinuance of Use for the Storage of Waste Military Munitions. When an
ASU that stored waste military munitions under CE is permanently taken out of service for the
storage of waste military munitions, but is to continue in service for the storage of non-waste
military munitions, installations and responsible activities shall ensure that waste military
munitions and residues are removed.

277 CHAPTER 14
DoD 6055.09-STD, February 29, 2008

C14.7. CLOSURE OF FACILITIES STORING WASTE MILITARY MUNITIONS

UNDER RCRA

In addition to those explosives safety requirements in section C1.4., closure procedures for those
sites operating under existing RCRA (Subpart EE of Parts 264 and 265 of 40 CFR (Reference
(an))) permits shall follow the closure requirements stipulated in the respective permit.

278 CHAPTER 14
DoD 6055.09-STD, February 29, 2008

C15. CHAPTER 15
UNEXPLODED ORDNANCE (UXO)

C15.1. SCOPE

This chapter establishes standards to protect personnel and property from explosive and CA
hazards (see Chapter 11) associated with UXO or other military munitions, to include DMM, that
have experienced abnormal environments. This chapter’s standards do not apply during
contingencies, combat operations, and military operations other than war; however, these
explosives safety principles should always be considered in such circumstances and applied as
the situation allows.

C15.2. GENERAL

C15.2.1. UXO are considered the most dangerous category of military munitions. However,
other military munitions, to include DMM, that are encountered outside the Department of
Defense’s munitions logistics management system, particularly those that have experienced an
abnormal environment, should be considered equally dangerous and managed as UXO until
assessed and determined otherwise by technically-qualified personnel (i.e., EOD personnel,
EOD-qualified U.S. Army Forces Command/20th Support Command/22nd Chemical Battalion
personnel and, when specifically authorized by a DoD Component, UXO-qualified personnel).
Military munitions that have experienced abnormal environments include, but are not limited to,
munitions remaining after attempted demilitarization by OB or OD; munitions involved in
accidents or fires; munitions or components subjected to certain tests (e.g., fuze arming tests, jolt
and jumble tests) that might cause arming. (U.S. Army Forces Command/20th Support
Command/ 22nd Chemical Battalion is manned with specially trained personnel that provide
verification, sampling, detection, mitigation, render safe, decontamination, packaging, escort,
and remediation of chemical, biological and industrial devices or hazardous materials.)

C15.2.1.1. UXO will most likely be found in areas that the Department of Department
currently uses (e.g., operational ranges) or once used (e.g., former ranges) for military munitions
training or testing. For a variety of reasons, UXO can also be encountered in other areas, to
include where contingency, combat, or military operations other than war have occurred.

C15.2.1.2. Munitions that may have experienced an abnormal environment might be

encountered in areas at which an accident or incident involving military munitions occurred, in
areas that the Department of Defense uses or once used for open detonation of excess, obsolete,
or unserviceable military munitions, or in other areas.

C15.2.2. Positive identification of any potential explosive or CA hazards and consideration

of the potential consequences of an intentional or accidental detonation is required before
disposition of any recovered munition. This is essential for munitions that might contain CA that
would pose a potential downwind CA hazard. Therefore, for both explosives and CA safety
reasons, munitions found outside the Department of Defense’s established logistical munitions

279 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

management systems (e.g., UXO, DMM) shall be managed as UXO, until assessed, identified,
and evaluated as to their explosive or CA hazards and determined otherwise by technically
qualified personnel. Munitions that contain an unknown liquid fill shall also be managed as
CWM until assessed, and the fill determined.

C15.2.2.1. Only EOD personnel and, in some cases, U.S. Army Forces Command/20th
Support Command/22nd Chemical Battalion personnel will respond to military or civilian
authority requests for support to an explosives or munitions emergency.

C15.2.2.2. For responses that either involve RCWM or munitions that contain an
unknown liquid fill, U.S. Army Forces Command/20th Support Command/22nd Chemical
Battalion personnel and, in cases where the munition’s physical characteristics allow positive
identification, EOD personnel, are the only DoD personnel authorized to determine the most
probable fill of such munitions. The determination as to whether certain munitions contain a CA
fill is difficult, if not impossible, solely by visual inspection.

C15.2.2.2.1. Many munitions have physical characteristics (e.g., shape, markings)

that permit technically qualified personnel to rule out the potential for a CA fill. For example, a
U.S.-manufactured 4-inch Stokes mortar’s physical dimensions clearly indicate whether it
contains a CA or explosive fill. However, the design or physical condition of some munitions
may not allow their complete identification by visual inspection. This is especially true for used
munitions and for munitions that have either experienced abnormal environments or been
exposed to the elements (e.g., buried or submerged) for an extended period.

C15.2.2.2.2. Munitions whose external design does not always allow positive visual
identification of their filler include, but may not be limited to: 4.2-inch mortars (M1, M2, and
the M2A1 models) and Livens projectiles (MKII (M1) and MKIIAI) models. U.S. Army Forces
Command/20th Support Command/22nd Chemical Battalion personnel and, in some cases, EOD
personnel, are the only DoD personnel authorized to determine the most probable fill of these
munitions.

C15.2.3. Discovery of military munitions (e.g., UXO) outside the Department of Defense’s
munitions logistics management system might, in some circumstances, indicate that a munitions
response (see Chapter 12) or other protective measures are warranted. DoD Components shall
notify the Chairman, DDESB, and their respective Service-level explosives safety office of:

C15.2.3.1. Repetitive explosives or munitions emergency responses to a discrete

geographic area, where the circumstances surrounding the explosives or munitions emergency
response are similar.

C15.2.3.2. A single explosives or munitions emergency response that involves multiple

military munitions (e.g., UXO, DMM, or RCWM) discovered at a discrete geographic area.
Such discoveries might indicate that the area is a FUDS.

C15.2.4. To meet the notification requirements of paragraph C15.2.3, DoD Components and
the Executive Manager for EOD Technology and Training are encouraged to jointly work toward

280 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

development of an explosives or munitions emergency response incident reporting system that

will ensure all incidents are similarly reported and retained in a single DoD database, which can
be queried, and will automatically identify the conditions of paragraph C15.2.3.

C15.3. DISPOSITION OF UXO AND OF OTHER MILITARY MUNITIONS BEING

MANAGED AS UXO

C15.3.1. The Department of Defense is responsible for protecting people, property, and the
environment from potential explosive hazards (e.g., blast and fragmentation) or CA hazards (e.g.,
downwind hazards) associated with DoD-owned UXO. The Department of Defense is equally
responsible for protecting personnel who respond to address such hazards.

C15.3.2. DoD Components shall work collaboratively with environmental regulators and
safety officials toward resolving, in a mutually agreeable manner, any concerns with the planned
disposition of UXO during a response action; however, the protection of people, to include DoD
response personnel, from the hazards associated with the discovered munition and with its
disposition is paramount.

C15.3.3. There are no safe procedures for moving, rendering safe, or destroying UXO, but
merely procedures considered less dangerous. Destruction-in-place (also referred to as blow-in-
place (BIP)) is the least dangerous; therefore, it is the preferred method of UXO destruction.

C15.3.4. DoD response actions to address UXO must comply with these Standards and other
applicable DoD policies and with applicable federal, state, interstate, and local laws and
regulations, and any enforceable agreements. DoD Components must ensure that, if not already
in place, protective measures (e.g., site security) are implemented as quickly as practicable
following discovery of UXO or other munitions outside the Department of Defense’s munitions
logistics management system. Should environmental regulators and safety officials have
concerns regarding the sufficiency of the protective measures to be taken, these concerns should
be raised to the appropriate-level DoD authority for resolution. Protective measures must be
maintained throughout any delay caused by:

C15.3.4.1. Compliance with laws, regulations, and agreements.

C15.3.4.2. The need to address concerns raised by environmental regulators and safety
officials about:

C15.3.4.2.1. Methods for managing any potential adverse impacts (e.g., harming
endangered species, damaging cultural resources) of implementing a pending BIP operation.

C15.3.4.2.2. The use of alternative (to BIP) disposition methods.

C15.3.4.3. Other factors (e.g., weather).

281 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C15.3.5. Military munitions known to contain CA or that contain or are suspected to contain
an unknown liquid fill will not normally be destroyed by open detonation because they pose
potential downwind CA hazards. The responsible DoD Component (normally the Department of
the Army), no lower than the Deputy Assistant Secretary level, may approve individual
exceptions. Such exceptions should only be approved after discussions (see paragraph C15.3.2.)
with appropriate elected representatives, environmental regulators, and safety officials from
those communities that could potentially be impacted by the munition’s disposition. DoD
Components must make sure that protective measures to ensure explosives safety are maintained
during any delay in disposition.

C15.3.6. UXO shall not be moved unless technically qualified personnel determine that the
risks associated with movement are acceptable. (During munitions responses, specifically
authorized UXO-qualified personnel may make this determination.) Although environmental
regulators and safety officials recognize the expertise of DoD personnel involved in UXO
disposition decisions, they may challenge a DoD field expert’s decision and seek to elevate their
concerns to higher levels of authority for resolution. (See paragraphs C15.3.2. and C15.3.4.)

C15.3.6.1. If technically qualified personnel determine that the risk associated with
movement is unacceptable, or if the munition’s condition precludes a complete assessment
beyond positive identification of any potential explosive hazard or determination that it does not
present a CA hazard, then it should be BIP.

C15.3.6.2. In some circumstances, EOD personnel may determine that careful movement
of a UXO, for a limited distance and using prescribed EOD procedures, is both necessary and
allowed by EOD procedures. In such circumstances, destruction by detonation will occur in the
general vicinity of discovery.

C15.3.7. Under some circumstances, when BIP does not pose an immediate, certain, and
unacceptable risk to people, critical operations, facilities, or equipment, environmental regulators
and safety officials may seek collaboration (see paragraph C15.3.2.) with DoD Components to
mutually agree to mitigation measures to reduce potential impacts of the pending BIP to public
safety, the environment, and cultural resources. (See paragraph C15.3.4.)

C15.3.8. When BIP poses an immediate, certain, and unacceptable risk to people, critical
operations, facilities, or equipment, EOD personnel may determine that render safe procedures
(RSP) should be attempted.

C15.3.8.1. Because the application of RSP exposes EOD personnel to added risks
(greater than BIP), the application of RSP shall only be attempted in limited circumstances.

C15.3.8.2. Should EOD personnel employ RSP, protective measures shall be applied to
mitigate potential explosive effects and, when necessary, a possible CA release.

C15.3.8.3. Only EOD personnel are authorized to conduct RSP.

C15.3.8.4. EOD personnel shall perform RSP per Joint Service EOD Technical Data.

282 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C15.3.8.4.1. Conflicts between this Standard and the Joint Service EOD Technical
Data should be raised to the Chairman, DDESB, and to the Joint EOD Program Board for
resolution.

C15.3.8.4.2. When the condition of UXO (e.g., crushed, bent, broken, mangled)
precludes strict adherence to published procedures, onsite EOD personnel will determine and
perform the procedure -- established or innovative -- that will have the most probable degree of
success to render the munitions safe while mitigating potential explosive or, when necessary, CA
effects.

C15.3.9. The onsite EOD supervisor or, in the case of munitions responses, the UXO safety
officer, shall ensure that the detonation site is inspected after each detonation or any misfire. No
one shall be allowed within MSD from the detonation site until the onsite EOD supervisor or
UXO safety officer declares the area is safe.

C15.3.10. When EOD personnel or, in the case of munitions responses, authorized UXO-
personnel, positively identify UXO as to its explosive hazard and determine it safe to dispose of
by other than BIP or immediate destruction by detonation, either in the general vicinity of
discovery or at a designated location, then technically qualified personnel or an appropriate-level
DoD authority with the advice of technically qualified personnel, may evaluate a variety of safe
disposition alternatives and options for managing any potentially adverse impact of the selected
disposition alternative. (See paragraph C15.3.2.)

C15.4. SPECIAL CONSIDERATIONS

C15.4.1. Disassembly and Inerting Operations

C15.4.1.1. Disassembly and inerting operations shall not be conducted without proper
authorization.

C15.4.1.2. DoD Components must establish procedures for authorizing such operations.

C15.4.2. Construction Support

C15.4.2.1. Construction support may be required during intrusive activities (e.g., laying
or repairing utilities, improving roads) on property known or suspected to contain UXO or
DMM.
C15.4.2.2. The responsible authority (e.g., installation commander or designated
representative) shall determine the level of construction support required on a case-by-case basis.
Construction support is determined by the probability of encountering UXO or DMM.

C15.4.2.2.1. Low Probability. EOD personnel or UXO-qualified personnel must be

contacted to ensure their availability, advised about the project, and placed “on call” to assist if

283 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

suspected UXO are encountered during construction. (Discoveries of UXO or DMM on such
sites requires reassessment of the level of support required.)

C15.4.2.2.1.1. A “low” determination may only be assigned to those areas for

which a search of available historical records and onsite investigation data indicates that, given
the military or munitions-related activities that occurred at the site, the likelihood that UXO or
other MEC are present is low.

C15.4.2.2.1.2. Munitions-related activities that may merit a “low” determination

include, but are not limited to, the use of the area: for live-fire training exclusively with small
arms ammunition; for maneuver training, to include maneuver training involving the use of
smokes, pyrotechnics, and simulators; as firing points; for munitions inspection, handling,
storage, or transfers, to include residue points and inert storage yards; for air defense; or as
munitions operating facilities, the exceptions being facilities in which the processes used might
have resulted in the generation of concentrations of munitions constituents high enough to
present an explosive hazard. Areas on which a previous response has been completed, pursuant
to a DDESB-approved ESS, for the stipulated reuse also qualify for “low” determinations.

C15.4.2.2.2. Moderate to High Probability. EOD personnel or UXO-qualified

personnel must attempt to identify and remove any explosive or CA hazards in the construction
footprint prior to any intrusive construction activities.

C15.4.2.2.2.1. A “moderate to high” determination may be assigned to those

areas for which a search of available historical records or onsite investigation data indicates that,
given the military or munitions-related activities that occurred at the site, there is more than a
low probability that UXO or other MEC are present.

C15.4.2.2.2.2. Munitions-related activities that may merit a “moderate to high”

determination include, but are not limited to, the use of the area: for live-fire training other than
exclusively with small arms ammunition (e.g., munitions containing high explosive projectiles);
as operational range impact areas; for OB or OD of excess, obsolete, or unserviceable munitions;
as munitions operating facilities where processes used might have resulted in the generation of
concentrations of munitions constituents high enough to present an explosive hazard; for
munitions burial; or for any activities involving possible disposition of CWM.

C15.4.3. Anomaly Avoidance. Anomaly avoidance techniques must be employed on

properties known or suspected to contain UXO or DMM to avoid surface UXO and, when
necessary, subsurface anomalies.

C15.4.3.1. When anomaly avoidance is used during training (e.g., maneuver training,
live-fire training), testing, or operational range management activities conducted on such
properties, the commander responsible for such activities will ensure:

C15.4.3.1.1. A risk assessment to evaluate the potential hazards associated with the
proposed activities is completed and methods to mitigate any potential exposures are
implemented.

284 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C15.4.3.1.2. Training in anomaly avoidance, explosives safety and, when

appropriate, CA safety training is provided to all personnel involved in the training, testing, or
operational range management activities that access property known or suspected to contain
UXO or DMM.

C15.4.3.2. When anomaly avoidance is used during other than training or testing
activities, or during activities involving other than operational range management activities:

C15.4.3.2.1. Surface UXO must be avoided during any activities that require entry to
the area (e.g., conducting cultural resource studies).

C15.4.3.2.2. Surface UXO and subsurface anomalies must be avoided during any
intrusive work (e.g., drilling environmental monitoring wells).

C15.4.3.2.3. Escort support must be provided by EOD personnel, or:

C15.4.3.2.3.1. Within areas known or suspected to contain UXO, excluding CA,

regardless of configuration, by:

C15.4.3.2.3.1.1. UXO-qualified personnel.

C15.4.3.2.3.1.2. UXO Technician I personnel under the supervision of UXO-

qualified personnel. The responsible commander or authority may, based on a risk assessment
and implementation of methods to mitigate any potential exposures, approve UXO Technician I
personnel to perform escort duties without supervision.

C15.4.3.2.3.2. Within areas known or suspected to contain CA, regardless of

configuration, to include areas where such CA is commingled with other UXO, by UXO-
qualified personnel trained in CWM responses.

C15.4.3.2.4. During anomaly avoidance:

C15.4.3.2.4.1. Discovered surface UXO must be avoided and their locations

noted and reported to appropriate authorities.

C15.4.3.2.4.2. Detected subsurface anomalies which must not be investigated

shall be marked, when appropriate, and avoided.

C15.5. ACCESS TO AREAS KNOWN OR SUSPECTED TO CONTAIN UXO

To ensure explosives and CA safety risk is identified and controlled on real property currently or
formerly under the jurisdiction, custody, or control of a DoD Component, DoD Components
must:

285 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C15.5.1. Prohibit unnecessary access (e.g., livestock grazing; recreational uses, such as
hunting and hiking) and take appropriate action to deter unauthorized access to areas under DoD
control that are known or suspected to contain UXO or other munitions that have experienced
abnormal environments.

C15.5.1.1. Access to such areas, particularly operational range impact areas, shall be
limited to personnel who have an operational requirement to enter such areas (e.g., range
maintenance, environmental monitoring, security). A risk assessment to evaluate the potential
hazards associated with the proposed activity shall be completed and methods to mitigate any
potential exposures shall be implemented before allowing access.

C15.5.1.2. Actions to prohibit or deter access may include establishing access controls
(e.g., fencing the area, establishing roving security patrols) and providing public notifications
(e.g., posting UXO hazard warning signs, conducting UXO safety education programs) of any
potential hazards. (When used, signs must be legible and, when appropriate, multi-lingual or
pictograms.)

C15.5.2. When the Department of Defense does not control the area (e.g., FUDS), at a
minimum, provide written notification to the property owner and, if known, any tenants of the
potential explosive and CA hazards present. A record of this notification must be maintained in
permanent records.

C15.5.3. Assume the following areas contain UXO or other munitions that have experienced
abnormal environments:

C15.5.3.1. Operational range impact areas, to include their associated safety zones (e.g.,
caution area, safety buffer zone). Exceptions include, but are not limited to, ranges used
exclusively for training with small arms ammunition.

C15.5.3.2. Ranges (sites) used for OB or OD of excess, obsolete, or unserviceable

munitions.

C15.5.3.3. Former impact areas and former OB or OD sites, unless documentation exists
to show that they were adequately cleared during range closure or that an appropriate munitions
response has been completed. In some cases, because these former impact areas or former OB or
OD sites may have transferred from DoD control, the Department of Defense’s ability to restrict
access may be limited or nonexistent. In such cases, the responsible DoD Component shall, at a
minimum, ensure that:

C15.5.3.3.1. The property owner is provided written notification of the potential

explosives and CA hazards and the risks inherent in any use of property that is inconsistent with
those hazards.

C15.5.3.3.2. A public UXO safety education program is implemented, when

appropriate.

286 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C15.5.4. On DoD property, prohibit construction in areas known or suspected to contain

UXO or DMM without required:

C15.5.4.1. Construction or UXO avoidance support. (See paragraphs C15.4.2. or

C15.4.3.)

C15.5.4.2. Approved ESS, CSS, or site plan for munitions responses. (See Chapter 12.)
C15.5.5. Provide, or in the case of owners or tenants of non-DoD controlled property, offer
explosives safety and, when appropriate, CA safety training to all individuals authorized access
to DoD property known or suspected to contain UXO.

C15.5.6. Develop guidelines to determine when individuals, who for operational reasons
(e.g., environmental monitoring), are authorized access to areas under DoD control that are
known or suspected to contain UXO, must be escorted into the area in accordance with
subparagraph C15.4.3.2.3.

C15.5.7. Establish UXO safety education programs to educate DoD personnel, their
dependents, and private citizens that live near areas known or suspected to contain UXO about
explosive hazards and, when appropriate, CA hazards associated with UXO, and with the risks
associated with trespassing on operational ranges or with entering areas known or suspected to
contain UXO.

C15.5.8. Prior to changing the use of a property known or suspected to contain UXO or
munitions that have experienced abnormal environments to a use that is incompatible with their
presence:

C15.5.8.1. For operational ranges, perform an appropriate range clearance, whether

changing to a similar (e.g., converting an impact area to a hand grenade range) or dissimilar use
(e.g., changing a range to a maneuver area).

C15.5.8.2. For areas on DoD property, other than operational ranges, perform an
appropriate munitions response.

C15.5.8.3. For property not under DoD control, upon learning of a proposed change in
use or pertinent munitions response action, offer to engage in munitions response activities only
to the extent necessary to ensure planned response actions afford protectiveness from an
explosives and CA safety perspective. The DoD engagement in such munitions response
activities may be limited to explosives safety experts providing basic guidance and advice during
applicable deliberations, decision making, and approval activities unless additional DoD services
are arranged through contractual or reimbursement mechanisms between DoD Components and
other responsible parties.

C15.6. IDENTIFICATION AND CONTROL

287 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

To ensure explosives and CA safety risk is identified and controlled on real property currently or
formerly under the jurisdiction, custody, or control of a DoD Component, DoD Components
must create and maintain permanent records required by paragraph C12.2.2. When an
operational range is closed or an installation is deactivated, the DoD Component concerned must
designate the office to transfer these records to ensure their permanent retention.

C15.7. MSD FOR UXO

C15.7.1. The MSD for intentional detonations (see Chapter 9), which may be reduced if
supported by a hazard assessment or when using approved engineering controls listed in EOD
publications (for explosives or munitions emergency responses), Reference (j), or other DDESB-
approved engineering controls (for munitions responses), is the greatest distance of:

C15.7.1.1. Blast overpressure, as computed by using the formula: D = 328W1/3

[D=130.16Q1/3].

288 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C15.8.1. Transportation. All transportation must comply with the requirements of applicable
federal, state, interstate, and local laws, and all implementing regulations relating to
transportation of solid waste, hazardous substances, hazardous materials, and toxic substances.

C15.8.1.1. UXO. Before UXO that may pose an explosive or CA hazard may be
transported or shipped over public transportation routes, EOD personnel must determine whether
the UXO is safe for transport. (For material potentially presenting an explosive hazard, see
subparagraph C16.3.3.2.) A determination that the UXO is safe for transport must be
documented in the EOD incident report. A copy of the incident report must accompany the
shipment.

C15.8.1.2. RCWM. Before RCWM may be transported or shipped, it must be assessed

by the Army Material Assessment Review Board as safe for transport and packaged in an
overpack container specifically designed and approved by the Army and by the DOT for the
transport of RCWM (see subparagraph C12.5.9.6.). In addition, the specific notifications and
concurrences required in 50 U.S.C. § 1512 (Reference (ao)) must be met.

C15.8.2. Firefighting Involving Areas Known or Suspected to Contain UXO or DMM. (See
Chapter 8.)

C15.8.2.1. Advanced planning is essential for firefighting operations involving areas that
are known or suspected to contain UXO or DMM or CA hazards. Coordination of such plans
between firefighters and explosives safety personnel or EOD personnel and, when appropriate,
CA safety professionals, is essential.

C15.8.2.2. Senior firefighting personnel should carefully assess whether to fight a fire
involving areas that are known or suspected to contain explosive or CA hazards. Factors to
consider include, but are not limited, to: the types of munitions that might be present; the safety
of firefighting personnel and of the public; the potential loss of critical assets; and the duration
and intensity of the fire.

C15.8.2.2.1. When the decision is made not to fight such fires, the area should be
evacuated and remain so until it has cooled for at least 24 hours. (See paragraph C8.5.4.)

C15.8.2.2.2. When the decision is made to fight such fires, all firefighters involved in
fighting the fire should be provided basic safety training for fighting fires involving military
munitions.

C15.8.3. Controlled Burns

C15.8.3.1. Burning vegetation to facilitate safe UXO clearance or removal operations is

permitted, provided proper safeguards are in place to protect all personnel from unintentional
detonations. These burns must be carefully planned and executed to manage explosives safety
risks and environmental effects. During such burning operations, all personnel shall be at MFD
from the burning or burned area, based on the MGFD, and shall remain out of the area until it
has cooled for at least 24 hours.

289 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C15.8.3.2. Controlled burns will not be performed on areas known or suspected to

contain CWM.

C15.8.4. Technology

C15.8.4.1. Explosives safety is a paramount consideration when determining the most

appropriate technologies to be used to detect, excavate, remove, and dispose of UXO and other
munitions that present an explosive hazard.

C15.8.4.2. The use of remotely operated equipment (e.g., excavators, sifters, and
shredders) or other standoff technologies (e.g., lasers) may offer the safest approach for
excavating and destroying UXO and should be considered.

C15.8.4.3. Subparagraph C12.5.8.3.5. addresses mechanized UXO processing

operations.

290 CHAPTER 15
DoD 6055.09-STD, February 29, 2008

C16. CHAPTER 16
MATERIAL POTENTIALLY PRESENTING AN EXPLOSIVE HAZARD (MPPEH)

C16.1. SCOPE

This chapter establishes explosives safety standards for MPPEH that supplement guidance
provided in DoD Instruction 4140.62 (Reference (ap)). These Standards are intended to protect
personnel and property from unintentional exposure to potential explosive hazards associated
with material (including waste material) being managed or transferred within or released from
DoD control.

C16.2. FUNCTIONS

C16.2.1. The Heads of the DoD Components shall establish criteria that may be risk-based
to determine and document whether a receiver, either a DoD Component or non-DoD entity, is
qualified to receive, manage, and process MPPEH through its release from DoD control These
criteria shall be coordinated with the DDESB and the Deputy Under Secretary of Defense
(Logistics and Material Readiness).

C16.2.2. The DDESB shall develop, through its coordination processes, specific explosives
safety management procedures and standards for determining the explosives safety status of
material and for processing MPPEH through its release from DoD control. The requirements of
Reference (ap) and other DoD issuances will be synchronized with these explosives safety
management procedures and standards.

C16.2.3. MPPEH, material documented as safe (MDAS), and material documented as

hazardous (MDAH) shall be managed in a manner that complies with explosives safety
standards, materiel management policies and environmental requirements. The effective
management of MPPEH, MDAS, and MDAH will help prevent the unauthorized or unintentional
transfer or release of an explosive hazard from DoD control; the transfer or release of material
documented hazardous to an unqualified receiver; or a shipment that violates hazardous material
transportation regulations.

present a significant risk during storage and transport, but not one great enough to be
unacceptable.

AP1.260. Without Means of Initiation. An AE item without its normal initiating device
assembled to it or packed with it. The term also applies to an AE item packed with its initiating
device, provided the device is packed so as to eliminate the risk of causing detonation of the AE
item in the event of accidental functioning of the initiating device. In addition, the term applies
to an AE item assembled with its initiating device, provided there are protective features such
that the initiating device is very unlikely to cause detonation of the AE item under conditions
that are associated with storage and transport. For hazard classification purposes, a means of
initiation that possesses two independent effective protective features is not considered to
present a significant risk of causing the detonation of an AE item under conditions associated
with storage and transport.

AP1.261. Zone of Protection. The space beneath the LPS that is substantially immune to direct
lightning.
