compatibility. However, in some cases it may also involve efforts to consolidate existing lots,
or to merge existing lots with inbound identical lots of ammunition.
(2) One of the biggest challenges of rewarehousing is remaining in compliance with established
explosive storage safety standards. Explosive storage standards are published in AR 385-64 and
TM 9-1300-206.
(a) One of the most difficult factors to monitor is maintaining quantity-distance (Q-D) standards.
Quantity-distance requirements are defined as those precautions taken to protect personnel
and property in the area adjacent to military establishments, and to reduce to a minimum the
possibility of any explosion involving large masses of explosives. The basis for computing
quantity-distance requirements is the net explosive weight (NEW) per storage site and
adjacent sites, and the hazard class and division for the ammunition stored therein.
(b) Ammunition and explosives are always hazard Class 1. Class 1 is further split into divisions
that indicate the character and predominance of associated hazards. Ammunition items in
Class 1, Division 1 (1.1) are mass detonating. Items in Class 1, Division 2 (1.2) are
nonmass-detonating, fragment producing. Class 1, Division 3 (1.3) items produce mass fire.
Items in Class 1, Division 4 (1.4) create moderate fire with no blast. Class 1, Division 5 (1.5)
items contain certain very insensitive explosives, and are considered the same as Class 1,
Division 1, compatibility group D.
(c) Ammunition without explosives which contains toxic chemicals is in hazard Class 6. The
hazard classes are based on their reaction to specified initiating influences. Fragment
distances are assigned to some items based on a known specific hazard. Since ammunition
is continuously being issued from or added to storage sites, Q-D is constantly changing.
Refer to the tables in Chapter 5 of TM 9-1300-206 to determine the Q-D requirements for
each change. Q-D usage is contained in ACCP MM0150.
(d) Ammunition compatibility is used to achieve the highest degree of safety possible for a given
storage site. All ammunition and explosives are assigned to storage compatibility groups
(SCGs) which, when stored together, will not significantly increase either the probability of an
accident or the magnitude of the effects of such an accident. Ammunition and explosives are
assigned to one of twelve SCGs. These SCGs are A through H, J, K, L and S. Table 5-19 of
TM 9-1300-206 provides an alphabetical listing of ammunition and explosive items by SCG.
Ammunition compatibility is covered in ACCP MM 0150. Ammunition and explosives should
be mixed in storage when such mixing will facilitate safe operations and promote overall
storage efficiency. Always refer to Figure 5-3 (Storage Compatibility Mixing Chart) in TM 9-
1300-206 to determine which items may be stored together. Special attention must be
applied when reading the notes under Figure 5-3. They allow for limited deviations from the
Figure.
(e) Whenever Q-D or compatibility standards cannot be accomplished, you must apply for a
waiver or exemption. Waivers or exemptions are requested through command channels to
the Chief of Staff, U.S. Army (CSA), or a lower level in the chain of command with approval
authority.
(3) Storage personnel utilize lot integrity and lot segregation as a tool for efficient storage space
management. Lot integrity involves rewarehousing to keep the maximum possible number
