c) Emergency alarms shall provide the capability of activating an
emergency alarm from each storage area and office. The sprinkler alarm system
shall be equipped to transmit alarms to the fire station or to a suitable
location that is continuously manned when a local fire station is not
available.
2.2.4
Security. The fence for the storage area shall be 15 feet from the
outside perimeter road of the facility. Except for Naval facilities, the
fence shall have a minimum height of 2 meters (6 feet) and shall be of the
chain-link type.
The standard perimeter or boundary fence that must be used by the
Navy to enclose restricted areas is defined in OPNAVINST 5530.14A, Physical
Security and Loss Prevention dated 16 Sep 1985. Specifically:
(1) Fabric. The standard fence fabric will be 9-gauge (3.8) mm)
zinc or aluminum-coated steel wire chain link with mesh openings not larger
than two inches (50 mm) per side and a twisted and barbed selvage at top and
bottom.
(2) Fabric Ties. Only 9-gauge (3.8 mm) steel ties will be used.
If the ties are coated or plated, the coating or plating will be
electrolytically compatible with the fence fabric to inhibit corrosion.
(3) Height. The standard height of a security fence is eight
(8) feet (2.4) meters). This includes a fabric height of seven (7) feet (2.1
meters), plus a topguard. Building connections may need to be higher.
Fencing 12 feet (3.6 meters) high from the connection point with a building to
a point 12 feet (3.6 meters) away from the building is suggested.
(4) Fencing Posts, Supports and Hardware. All posts, supports,
and hardware for security fencing will meet the requirements of Federal
Specification RR-F-191J/GEN of 22 July 1981. All fastening and hinge hardware
will be secured in place by peening or welding to allow proper operation of
components, but prevent disassembly of fencing or removal of gates. All posts
and structural supports will be located on the inner side of the fencing.
Posts will be positively secured into the soil to prevent shifting, sagging or
collapse.
(5) Reinforcement. Taut reinforcing wires will be installed and
interwoven or affixed with fabric ties along the top and bottom of the fence
for stabilization of the fence fabric.
(6) Ground Clearance. The bottom of the fence fabric must be
within two inches (50 mm) of firm soil or buried sufficiently (concrete
footings or gravel may be used) in soft soil to compensate for shifting soil.
(7) Culverts and Openings. Culverts under or through a fence
shall be of ten inch (254 mm) pipe, or of clusters of such pipe or equivalent.
Openings under or through a fence will be secured with material equal or
greater in strength than the overall barrier.
