CATEGORY C. This category of material
presents an explosion hazard. This category includes
bombs, warheads, depth charges, mines, demolition
material, and bulk explosives. Category C material
should be separated from materials in the other
categories by at least 695 feet.
CATEGORY D. This category of material
includes fuzes and detonators. Category D material
should be separated from materials in the other
categories by at least 200 feet.
CATEGORY E. This category of material
includes chemical ammunition. Category E material
should be separated from materials in the other
categories by at least 400 feet.

be a minimum of what distance from
ammunition storage sites and inhabited
areas?

magazine at an advanced base.

an
advanced

MAGAZINE MAINTENANCE,
STORAGE, AND HANDLING
REQUIREMENTS
LEARNING OBJECTIVE: Identify the types
of procedures used for magazine maintenance,
storage, and handling to include personnel
requirements, lightning protection systems,
magazine security, and ammunition handling
and shipping.
Proper
explosives
and
ammunition
storage
facilities are only a part of the overall storage system.
Among the most important aspects of the storage of
ammunition is the proper maintenance of magazines
and magazine areas.
PERSONNEL REQUIREMENTS
Normally, all personnel engaged in operations that
involve ammunition, explosives, and other hazardous
materials are trained and qualified to perform their
assigned duties. In addition to being qualified and
certified, personnel involved with hazardous explosive
operations are certified by a physician as physically
qualified. Personnel aren't knowingly permitted or
required to work when their ability or alertness is
impaired because of fatigue, illness, or other reasons.
This would expose them and other personnel to injury.
Occasionally, manpower shortages cause a need for
assistance by personnel from other Navy ratings to join
working parties to handle or transport ammunition and
explosives. These working parties are referred to as
augmentation crews. Before using augmentation crews,
try to make sure that personnel in the working party are
trained so mistakes aren't made or safety factors
violated. Furthermore, make sure enough qualified
representatives, preferably officers or petty officers that
are senior in rank to any member of the working party,
are present to detect or prevent violations of safety
orders and other unsafe practices. They should take
whatever action is required to correct the situation.
LIGHTNING PROTECTION SYSTEMS
Lightning protection is required for all ordnance
handling buildings, storage facilities, and handling
areas that have more than 5 days per year when
thunderstorms occur.
There are two types of lightning protection
systems—primary and secondary. The primary system
prevents damage from direct lightning strikes by
diverting the strike and providing a low-impedance
path to ground. The secondary system maintains all
metal objects within its system at the same electrical
potential. This prevents the possibility of sparking
between the objects.
Primary Systems
There are two types of primary lightning protection
systems
acceptable
to
NAVSEASYSCOM—the
separately mounted lightning mast system and the
separately mounted overhead ground (aerial shield)
wire system.
LIGHTNING MAST SYSTEM.—This type of
primary
system
consists
of
lightning
masts
(freestanding air terminals) placed around a facility and
connected to a buried primary girdle. A sufficient
number of masts are used to protect the entire structure
within the combined cones of the masts. The
dimensions of the structure determine the number and
