In addition, the following information must be
conspicuously posted on one door in each magazine or
building that contains ammunition:
(explosion, fire, or fragment) stored there.
The maximum quantities of ammunition in
each hazard classification as determined from
the explosive safety quantity-distance tables.
Safety precautions and regulations that pertain
to the specific material presently stored in the
magazine or building.
Post this information at each outside (open)
ammunition storage site. Print the information on a card
so it is protected from the weather. Then, put the card in
a locally manufactured ammunition site sign and
cardholder, as shown in figure 12-3.
Advanced base magazines are built in the most
suitable location for storing one of the three hazard
classificationsexplosion, fire, or fragment. Since all
advanced base magazines are of the same type of
construction, all three-hazard classifications may be
stored in them if they are within ESQD limitations.
However, the group construction symbol designates the
type of storage for which the magazine is most suitable.
Don't change this symbol to show the magazine's
present or new use, unless the change is permanent.
DISPURSION OF AMMUNITION
Ammunition disbursement is a main consideration
in laying out an ammunition storage area at an
advanced base. Each type of ammunition is stored in
two widely separated areas. This prevents losing an
entire supply of an ammunition item if there is a fire or
explosion. Explosive stores are separated from other
stores, as specified in the ESQD tables.
Group piles of ammunition stored in the open by
categories. These groups are discussed in the following
paragraphs. These groupings aren't compatibility
groups; they are only used to ensure safe distances are
maintained between piles and stacks of ammunition.
CATEGORY A. This category of material
presents a fire hazard. It includes propelling charges,
bag charges, rocket motors, pyrotechnics, and small
arms ammunition. Category A material should be
separated from materials in the other categories (B
through E) by at least 350 feet.
CATEGORY B. This category of material
presents fire and fragment or fragment and explosion
hazards. It includes fixed ammunition, separate-
loading projectiles, complete rockets (assembled or
unassembled), grenades, and mortars. Category B
material should be separated from materials in the other
categories by at least 300 feet.
