WIRE SYSTEM.This system consists of overhead
lightning protection conductors spanned between
lightning masts above a facility. The conductors are
connected to a buried ground girdle or to ground rods
only, depending upon the type of installation.
The secondary lightning protection system consists
of a buried girdle to which all metal parts are connected
at the lowest point. This implies that electrical access to

MAGAZINE AND MAGAZINE AREA
Nonclimbable fences protect magazine areas. All
the entrances are locked unless guards are posted. Post
a sign at all the entrances to restricted areas. The sign
indicates that every vehicle must stop, that each person
must present proper credentials to the guard, and that
all articles prohibited within the area must be given to
the guard. The exact wording of the signs are left to the
discretion of the commanding officer. However, the
word explosive doesn't appear on the sign, and the sign
isn't attached to the magazines.
Special precautions are taken to guard or patrol the
areas that not protected by suitable fencing. Magazine
and explosives areas where ammunition, explosives,
and other items of high-security classification are
stored must be adequately guarded at all times.
Don't let unauthorized personnel enter or remain in
any magazine or explosives area. Personnel involved in
ammunition handling operations are authorized in
magazines or buildings that contain explosives only as
required, and they must enter and leave explosives areas
at designated points.

A prefabricated magazine at an advanced
base is an earth-covered, arch-type structure.
Category A poses a fire hazard.
The commanding officer, or duly authorized
representative, requires regular and frequent magazine
inspections. These inspections include ready-service
lockers, ready-service magazines, and magazine areas.
Magazine inspections are conducted to make sure the
following conditions are met:
Ensure magazine repairs are made, if needed.
Ensure that safety regulations, particularly those
that involve cleanliness and elimination of fire
hazards, are observed.
Ensure that magazine contents are not
deteriorating into an unsafe condition, and they

The magazine area inspections are designed to
make sure the following actions are being maintained:
Firebreaks are being maintained.
Fire protection equipment, when required, is
available and serviceable.
Roads are good and in usable condition.
Fences are secure.
At times area inspections are performed more often
than magazine inspections, particularly during seasons
when grass or brush fires are most likely to occur.
