Fix Recommendation

All secure room doors (*containing inspectable SIPRNet assets) must meet the following standards:

1. The doors to the room (primary and secondary) shall be substantially constructed of wood or metal.

2. For outswing doors, hinge-side protection shall be provided by making hinge pins nonremovable (i.e., spot welding) or by using hinges with interlocking leaves that prevent removal. There are certain hinge pins made with internal locking pins or locking flanges and are acceptable if they cannot be removed.

3. Secondary (emergency exit only) doors other than those secured with locks meeting FF-L-2740 shall be secured from the inside with deadbolt emergency egress hardware, a deadbolt, or a rigid wood or metal bar that extends across the width of the door. IAW Unified Facilities Criteria (UFC) UFC 4-026-01, 4 Mar 2020, section 5-5.5. All nonentry doors to the defense layer must present a blank, flush surface to the outside and have internal locking or bolting mechanisms to reduce vulnerability to attack (to the secure room).

4. Secondary doors (doors other than those secured with locks meeting FF-L-2740) shall be secured from the inside with deadbolt emergency egress hardware, a deadbolt, or a rigid wood or metal bar that extends across the width of the door. These deadbolt locks shall be secured when the combination lock on the primary door is spun.

TACTICAL ENVIRONMENT: This check is applicable where secure rooms are used to protect classified materials or systems. The only exception will be for urgent (short term) tactical operations or other contingency situations where fixed facilities and equipment are not yet present or incapable of being used.
