a normally closed to an open position (for access).
219. Combat aircraft parking area. Any area specifically designated
for:

the probability of an accident or, for a given quantity, the magnitude
of the effects of such an accident.
214. Connected-chamber storage site. A chamber storage site consisting
of two or more chambers connected by ducts or passageways. Such chambers
may be at the ends of branch tunnels off a main passageway.
2225. Controlling authority. The headquarters of the DoD Component
concerned.
2326. Debris. Any solid particle thrown by an explosion or other strong energetic reaction. For aboveground detonations, debris usually refers to secondary fragments. For underground storage facilities, debris refers to both primary and secondary fragments, which are transported by a strong flow of detonation gasses.
2427. Debris trap. A protective construction feature in an underground
storage facility which is designed to capture fragments and debris from
a detonation within the facility. This is usually accomplished by using
the inertia of the material to separate it from the detonation gas stream.
(Illustrated in Figure 9-3)
2528. Deflagration. A rapid chemical reaction in which the output
of heat is enough to enable the reaction to proceed and be accelerated
without input of heat from another source. Deflagration is a surface phenomenon
with the reaction products flowing away from the unreacted material along
the surface at subsonic velocity. The effect of a true deflagration under
confinement is an explosion. Confinement of the reaction increases pressure,
rate of reaction and temperature, and may cause transition into a detonation.
2629. Detonation. A violent chemical reaction within a chemical
compound or mechanical mixture evolving heat and pressure. A detonation
is a reaction which proceeds through the reacted material toward the unreacted
material at a supersonic velocity. The result of the chemical reaction
is exertion of extremely high pressure on the surrounding medium forming
a propagating shock wave that originally is of supersonic velocity. A detonation,
when the material is located on or near the surface of the ground, is characterized
normally by a crater.
2730. Dividing wall. A wall designed to prevent, control, or
delay propagation of an explosion between quantities of explosives on opposite
sides of the wall.
2831. DoD mishap. An unplanned event or series of events that
result in damage to DoD property, occupational illness to DoD military
or civilian personnel, injury to DoD military personnel on or off duty,
injury to on-duty civilian personnel; damage to public and private property,
or injury and illness to non-DoD personnel as a result of DoD operations.
2932. Dolphin. A mooring post or posts on a wharf or quay.
3033. Donor/acceptor. A total quantity of stored ammunition may
be subdivided into separate storage units in order to reduce the MCE, and,
consequently, the Q-D of an accidental detonation. The separation distances,
with or without an intervening barrier, should be sufficient to ensure
that a detonation does not propagate from one unit to another. For convenience
the storage unit which detonates is termed the donor, and nearby units,
which may be endangered, are termed acceptors. The locations of the donor
and acceptor define the PES and ES, respectively.
3134. Engineering controls. Regulation of facility operations
through the use of prudent engineering principles, such as facility design,
operation sequencing, equipment selection, and process limitations.
3235. Expansion chamber. A protective construction feature in an underground storage facility which is designed to reduce the blast shock and overpressure exiting the facility by increasing the total volume of the complex. It may also function as an operating area within the underground facility, as well as a debris trap. (Illustrated in Figure 9-3)
3336. Explosion. A chemical reaction of any chemical compound
or mechanical mixture that, when initiated, undergoes a very rapid combustion
or decomposition releasing large volumes of highly heated gases that exert
pressure on the surrounding medium. Also, a mechanical reaction in which
failure of the container causes the sudden release of pressure from within
a pressure vessel, for example, pressure rupture of a steam boiler. Depending
on the rate of energy release, an explosion can be categorized as a deflagration,
a detonation, or pressure rupture.
3437. Explosives facility. Any structure or location containing
ammunition and explosives excluding combat aircraft parking areas or ammunition
and explosives aircraft cargo areas.
38. Exposed site (ES). A location exposed to the potential hazardous effects (blast, fragments, debris, and heat flux) from an explosion at a potential explosion site (PES). The distance to a PES and the level of protection required for an ES determine the quantity of ammunition or explosives permitted in a PES.
369. Forward Arming and Refueling Point (FARP). A temporary facility,
organized, equipped and deployed by an aviation commander, and normally
located in the main battle area closer to the area of operation than the
aviation unit's combat service area, to provide fuel and ammunition necessary
for the employment of aviation maneuver units in combat. The FARP permits
combat aircraft to rapidly refuel and rearm.
3740. Firebrand. A projected burning or hot fragment whose thermal
energy is transferred to a receptor.
4138. Fragmentation. The breaking up of the confining material
of a chemical compound or mechanical mixture when an explosion takes place.

any two operating buildings and sites within an operating line, of which
at least one contains or is designed to contain explosives, except that
the distance from a service magazine for the line to the nearest operating
building may be not less than the intraline distance required for the quantity
of explosives contained in the service magazine.
55. K-factor. The factor in the formula D=KW 1/3 used
in quantity-distance determinations where D represents distance in feet
and W is the net explosive weight in pounds. The K-factor is a constant

cryogenics) used for propulsion or operating power for missiles, rockets,
ammunition and other related devices (See Table 9-17). For purposes of
this standard, liquid fuels and oxidizers are considered propellants even
when stored and handled separately.
596. Loading density. Quantity of explosive per unit volume .
usually expressed as either pounds per cubic foot (lbs/ft3)
or kilograms per cubic meter (kg/M3). As applied to underground

certain pyrotechnics, and other similar explosives, alone or in combination,
or loaded into various types of ammunition or containers, most of the entire
quantity of which can be expected to explode virtually instantaneously
when a small portion is subjected to fire, to severe concussion or impact,
to the impulse of an initiating agent, or to the effect of a considerable
discharge of energy from without. Such an explosion normally will cause
severe structural damage to adjacent objects. Explosion propagation may
occur immediately to other items of ammunition and explosives stored sufficiently
close to and not adequately protected from the initially exploding pile
with a time interval short enough so that two or more quantities must be
considered as one for Q-D purposes.
6632. Maximum credible event (MCE)
a. General. In hazards evaluation, the MCE from a hypothesized
accidental explosion, fire, or agent release is the worst single event
that is likely to occur from a given quantity and disposition of ammunition
and explosives. The event must be realistic with a reasonable probability
of occurrence considering the explosion propagation, burning rate characteristics,
and physical protection given to the items involved. The MCE evaluated
on this basis may then be used as a basis for effects calculations and
casualty predictions.
67. Military munitions. All ammunition products and components

warheads are defined as non-robust.
8954. Rock strength. Strong, moderately strong, and weak rock are designators which provide a general classification of rock types for siting underground storage facilities for ground shock hazards. Classification of a rock body into one of these three rankings is based on the rock impedance factor:

where
g is the rock density, lbs/ft3
g is the gravitational acceleration, ft/sec2
r is the mass density of the rock, lbs-sec2/ft4
c seismic velocity of the rock, ft/sec.
The rock impedance factor will be 0.75 or more for strong rock; between
0.75 and 0.5 for moderately strong rock; and less than 0.5 for weak rock.
Values of these parameters can usually be estimated based on examinations
of exposed rock outcrops or core samples from an exploratory drill hole.

by which they are formed) that are broken loose from the surface of a parent
body by tensile forces that are created when a compression shock wave travels
through the body and reflects from the surface. For underground storage,
spall normally refers to the rock broken loose from the wall of an acceptor
chamber by the shock wave transmitted through the rock from an explosion
in a nearby donor chamber.
