Interior Physical Security
Delay Times. Guidelines for selecting and designing facility
components to meet specified delay times are provided in MIL-HDBK-1013/1.
Procedures for determining delay times, if not specified by the IDSEP or the
user command, are given in MIL-HDBK-1013/1.
Building Layout. Portions of the building requiring special
security consideration will be identified by the IDSEP or by the user command.
Wall Construction. Design secure area wall using 4 inches of
reinforced concrete or 8 inches of solid masonry, without windows, and with
controlled access. Refer to DIAM 50-3 and MIL-HDBK-1013/1.
other types of construction are provided in MIL-HDBK-1013/1. False ceilings
or raised floors provide a means of concealment. False ceilings or floors are
considered part of the protected area to which they are attached; therefore,
ensure the true walls, floors, and ceilings meet the applicable requirements.
Provide at least one quick-remove access panel, 18 by 18 inches, for each 400
square feet of false ceiling or floor area.
Exterior Doors. Provide entry and exit doors of secure areas as
specified in the IDSEP or DIAM 50-3. Provide exterior doors with delay times
commensurate with those of the structure in which they are installed.
Windows, Air Vents, and Ducts. Windows, ducts, and other openings
that breach the facility perimeter require protection as specified in DIAM
50-3 and MIL-HDBK-1013/1. Openings which exceed the man passable size of 96
square inches require protection.
Roof Doors and Hatches. Secure roof doors and hatches with internal
padlocks and hasps meeting the provisions of MIL-P-43607, Padlock, Key
Operated, High Security, Shrouded Shackle. Alternatively, provide roof doors
with a cylindrical case or bored lockset. Mount such locksets, when
installed, with the lock cylinder to the exterior.
Cipher Locks. If required for control of routine access, install an
electrically controlled and operated latch mechanism for interior doors.
Ensure radio frequency (RF) emissions meet the requirements of Military
Standard MIL-STD-461, Electromagnetic Emission and Susceptibility
equipment. Ensure mechanisms do not mate or interface with other locksets.
Add separate surface-mounted night latches or specialty hardware to the door
to accommodate the electrically operated mechanism. Do not use key-operated
