6/9, Physical Security Standards for Sensitive Compartmented Information
Facilities (SCIF) and MIL-HDBK-1013/1.
3-7.3.4
Roof and Floor Construction.
Provide at least 101.6 mm (4 in.) of reinforced concrete for roof and floor
construction. Hardening methods for 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, 457 by 457 m (18 by 18 in.), for each 142 m2 (400 ft2) of false ceiling or
floor area.
3-7.3.5
Exterior Doors.
Provide entry and exit doors of secure areas as specified in the IDSEP or DCID
6/9. Provide exterior doors with delay times commensurate with those of the
structure in which they are installed.
3-7.3.6
Windows, Air Vents and Ducts.
Windows, ducts, and other openings that breach the facility perimeter require
protection as specified in DCID 6/9 and MIL-HDBK-1013/1. Openings that
exceed the man-passable size of 600 mm2 (96 in2) require protection.
3-7.3.7
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.
3-7.3.8
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 MIL-STD-461, Electromagnetic Emission
and Susceptibility Requirements for the Control of Electromagnetic Interference,
for Class II-A 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 bypass cylinders.
3-7.4
Vaults.
