(8) Fence Placement. No fence will be located so that the
features of the land (its topography) or structures (buildings, utility
tunnels, light and telephone poles, fire escapes, ladders, etc.) defeat its
purpose by allowing passage over, around or under the fence.
(9) Top Guards. A top guard must be constructed on all perimeter
fences and may be added on interior enclosures for additional protection. A
top guard is an overhang of barbed wire or barbed tape along the top of a
fence, facing outward (away from protected site) and upward at approximately a
45-degree angle. Top guard supporting arms will be permanently affixed to the
top of fence posts to increase the overall height of the fence at least one
(1) foot (0.3 meter). Three strands of 12-gauge (2.7 mm) barbed wire, equally
spaced, must be installed on the supporting arms. The top guard of fencing
adjoining gates may range from a vertical height of 18 inches (0.45 meter) to
the normal 45-degree outward protection, but only for sufficient distance
along the fence to open the gates adequately.
(10) Barriers. Buildings, structures, waterfronts and other
barriers used instead of (or as a part of) a fence line must provide
equivalent protection to the fencing required for that area. Therefore, all
windows, doors and other openings or means of access must be guarded or
properly secured.
b) Alternative Fencing. Where a boundary passes through an isolated
area (forest, jungle, swamp) that is unpatrolled and where vehicular passage
is impossible, the boundaries may be defined with a three or four strand
12-gauge (2.7 nm) barbed wire fence approximately four (4) feet (1.2 meters)
high. It will be posted as required.
Alternative fencing may be used only to define a perimeter boundary;
it shall not be used to enclose restricted areas.
2.2.5
Electrical.
a) The fenced-in yard area shall be illuminated to a level of 0.1
foot-candle.
b) Interior lighting will generally be provided in accordance with
DOD MIL-HDBK-1190. Lighting in storage areas will be sufficient to ensure
immediate location of leaks upon inspection.
c) All raceways shall be designed and installed in accordance with
the National Electric Code, National Fire Protection Association, NFPA-70, for
hazardous locations.
2.3
Housing Requirements. This manual covers the design of long-term
storage facilities. The general design criteria are summarized in Table 1.
Additional considerations are listed below:
2.3.1
Office. Facilities may require office space although not
necessarily colocated with the storage site. Access to a computer terminal is
recommended for large-scale record and inventory control.
