REVIEW NUMBER 2
Describe the purpose of an advanced base.
What publication governs ammunition storage
at advanced bases?
What is the purpose of having at least two
storage areas for each type of ammunition at an
advanced base?
The disposal area at an advanced base should
be a minimum of what distance from ammunition
storage sites and inhabited areas?
List the characteristics of a prefabricated
magazine at an advanced base.
At an advanced base, ammunition in Category A
poses what sort of hazard?
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 apart 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 number
and height of masts required to adequately protect a
structure is determined by the dimensions of the
structure.
OVERHEAD GROUND (AERIAL SHIELD)
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.
Secondary System
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 all reinforced steel must be provided during
