(b) The vault may be required to remain open for frequent access. If so, it must
have a self-closing and self-locking "day gate" or its equivalent. A day gate is not needed if the vault is
not opened often, and it is relocked immediately after use.
(b) At an existing facility where it is not possible to construct the type vault described above,
select a storage site as follows.
(1) The room or building should have walls made of masonry. They should extend from
floor to ceiling with reinforced concrete ceiling and floor. If this is not possible, the structure should be
built of wood and made as sound as possible. The inside will have the walls, floors, and ceiling lined
with 1 inch thick lumber or 1/2 inch plywood. Steel mesh will be affixed, and smooth-headed bolts or
rivets will be peened on the inside. This will prevent removal from the outside.
(2) Limit the number of windows to as few as possible. Block up all other windows if you
can. Protect the remaining windows with steel mesh or bars. These must be welded to a steel channel
frame and fastened to the building by smooth-headed bolts imbedded in the structure.
(3) Limit doors. If a vault-type door is not used, the entrance will be a two-door back-to-
back system. Build the outer door of solid wood at least 1 3/4 inch thick. This door will be covered with
a sheet of steel, not less than 1/16 inch thick (16 gauge USS). Build the inner door of steel bars welded
to a grid, with openings that do not exceed 32 square inches; or you may use a solid wood door with
the same particulars as the outer door. Install door hinges so that it will not be possible to remove the
closed doors without greatly damaging the door frame. Spot weld hinge pins to prevent removal.
Secure the outer door with a high security lock and hasp. Secure the inner door with an approved
secondary padlock, a combination lock, and hasp.
(c) Store Note Q items under the same criteria as Note R items. The dual back-to-back
door protection may be ignored provided the entrance door is solid wood. Also, it must be a minimum
of 1 3/4 inches thick and covered with a sheet of steel not less than 1/16 inch thick. Secure the door
with a high security padlock and hasp and hang on security-type hinges.
(d) Store Note C chests, kits, outfits under guidance outlined above for Note R and Q items.
2. Special Handling Procedures.
a. Drugs. As noted before, drugs and controlled medical items are assigned letter designators,
and the degree of physical security depends on the category. AR 190-51, Chapter #4, provides
minimum guidance for handling controlled substances. Some general measures applicable to handling
such items include the following:
