c. Shipping containers, cases, etc., are inspected to ensure they are empty;
cardboard boxes will be flattened before disposal.
12. Building Security. Buildings and rooms are considered secure storage structures if
they meet the following standards:
a. Doors provide a degree of security comparable to the walls provided by the
b. Door hinge mounting screws are not exposed to the exterior of the facility. If
screws are exposed, they will be spot welded, covered, or filled with material in a way to
prevent easy removal. Nails will not be used to mount hinges.
c. Door hinge pins exposed to the exterior of the facility are of a design (or have
been modified) to prevent easy removal.
d. Doors to the exterior locked from the inside will be secured with a dead bolt
locking device, crossbar, or similar locking device resistant to jimmying and
manipulation from the outside as opposed to a latch style door lock.
Windows will have individual locking devices.
f. All first floor openings, except doors, in excess of 96 square inches that are
located less than 12 feet from the ground will be barred, grilled, or covered with chain
link material in a way as to preclude easy removal.
g. Doors secured from the outside will have locking devices conforming to proper
Corps of Engineers guide specifications for the structure or with U.S. Government
tumbler-type, key-operated padlocks.
h. Walls, floor, and ceiling are constructed of at least 1/2-inch plywood, 1- inch
tongue in groove wallboard, or the equivalent.
13. Security of Subsistence Items. Subsistence warehouses, rooms in dining facilities, or
other buildings used to secure nonrefrigerated food stuffs, to include field rations for
contingency purposes, will be secured at all times when entrances or exits are not under
the surveillance of personnel permanently assigned to the facility, such as warehouse
personnel and cooks. Government, key-operated type padlocks will be used for this
purpose except in instances in which a commercially installed locking device exists.
a. Refrigeration units with locking devices will be secured. If this is not possible,
the room or building in which the refrigeration unit is located will meet the physical
protection standards as already explained.
