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.

a. Chamber loading density is based on the NEW within an individual storage chamber and the volume of the chamber (VCH).
 
 

    1. b. The calculation of airblast peak pressures and lBD's IBDs for explosions in underground
storage facilities is based on the shock-engulfed volume (VE) of the facility. This is the total volume filled by the expanding gases at the time the blast front reaches the point of interest (e.g., the entrance to an adjacent chamber). It includes volumes in any direction that the gases can enter, to a distance from the explosion source that equals the distance from the source to the point of interest.

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.
 
 

    1. b. Chemical agent. An MCE for a chemical agent is defined as the hypothesized
maximum quantity of agent that could be released from an ammunition item (without explosives), bulk container, or process as a result of a single unintended, unplanned, or accidental occurrence. It must be realistic with a reasonable probability of occurrence.

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

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.

a. An unused military munition is a solid waste when any of the following occurs:
 
 

c. For purposes of RCRA section 1004(27), a used or fired military munition is a solid waste, and, therefore, is potentially subject to RCRA corrective action authorities under section 3004(u) and (v), and section 3008 (h), or imminent and substantial endangerment authorities under section 7003, if the munition lands off-range and is not promptly rendered safe and/or retrieved. Any imminent and substantial threats associated with any remaining material must be addressed. If remedial action is not feasible, the operator of the range must maintain a record of the event for as long as any threat remains. The record must include the type of munition and its location (to the extent the location is known). For further clarification see 40 CFR 266.202 under Definition of Solid Waste.
