Sec. 2001.52  Open storage areas [4.1].

    This section describes the construction standards for open storage 
areas.
    (a) Construction. The perimeter walls, floors, and ceiling will be 
permanently constructed and attached to each other. All construction 
must be done in a manner as to provide visual evidence of unauthorized 
penetration.
    (b) Doors. Doors shall be constructed of wood, metal, or other solid 
material. Entrance doors shall be secured with a built-in GSA-approved 
three-position combination lock. When special circumstances exist, the 
agency head may authorize other locks on entrance doors for Secret and 
Confidential storage. Doors other than those secured with the 
aforementioned locks shall be secured from the inside with either 
deadbolt emergency egress hardware, a deadbolt, or a rigid wood or metal 
bar which extends across the width of the door, or by other means 
approved by the agency head.
    (c) Vents, ducts, and miscellaneous openings. All vents, ducts, and 
similar openings in excess of 96 square inches (and over 6 inches in its 
smallest dimension) that enter or pass through an open storage area 
shall be protected with either bars, expanded metal grills, commercial 
metal sounds baffles, or an intrusion detection system.
    (d) Windows. (1) All windows which might reasonably afford visual 
observation of classified activities within the facility shall be made 
opaque or equipped with blinds, drapes, or other coverings.
    (2) Windows at ground level will be constructed from or covered with 
materials which provide protection from forced entry. The protection 
provided to the windows need be no stronger than the strength of the 
contiguous walls. Open storage areas which are located within a 
controlled compound or equivalent may eliminate the requirement for 
forced entry protection if the windows are made inoperable either by 
permanently sealing them or equipping them on the inside with a locking 
mechanism and they are covered by an IDS (either independently or by the

motion detection sensors within the area.)
