duties as an explosives driver take a good look at the
requirements you must meet to become certified to
drive motor vehicles that transport ammunition,
explosives, and hazardous materials.
Lets continue now with the requirements for
storing these hazardous materials safely.
Q7. What NAVSEA OP should you use to find general
instructions for preparation and shipping
As a Fire Controlman, you will be responsible
for the care of projectiles, missiles, and associated
components while they are in stowage. This is an
important task because these weapons and
components will spend about 99 percent of their
existence in stowage. This care is even more
important aboard surface ships and submarines.
Why? Because at shore stations weapons are stored
in their shipping containers inside magazines.
Aboard surface ships these weapons are stowed in
missile tubes or magazines and are exposed to salt
water and humidity. A large part of your job will
involve maintaining the environmental control and
fire suppression systems in magazines.
A magazine is any compartment, space, or locker
used, or intended to be used, for ammunition stowage.
From the magazine, we can expand to the magazine
area. A magazine area includes all compartments,
spaces, or passages next to or surrounding a magazine.
These places are used, or intended to be used, as the
area for handling and passing ammunition. The areas
around loaded freighters, railroad cars, and trucks are
treated as magazine areas, too. The safety and security
measures that apply to shipboard magazines and
magazine areas also apply to these portable units.
Each magazine is specifically designed for the
ammunition it will contain. As a general rule, different
types of ammunition will be stowed in separate
magazines or lockers. The highest possible degree of
safety is obtained by not mixing different explosives in
the same magazines or lockers.
However, there are exceptions to this rule. Some
stowage areas can be designated single-purpose or
multipurpose magazines. While single-purpose
stowage is desirable, it is not always possible. Often a
ships mission requires it to carry a variety of
ammunition. Mixed-stowage in multipurpose and
certain single-purpose magazines is acceptable. But,
there are limitations and restrictions to
mixed-stowage. Current safety instructions must be
followed and proper authorization must be obtained
for mixed-stowage. When mixed-stowage is
authorized, it must conform, as close as possible, to the
permissible stowage tables listed in NAVSEA OP 4,
There are five major types or classes of magazines.
We will discuss the four types you will most likely
encounter: primary magazines, missile magazines,
ready-service magazines, and lockers. The fifth type is
called a chemical magazine. Only lethal and
incapacitating chemical ammunitions will be stowed
in these extremely special magazines. Normally,
chemical ammunition is not carried aboard ship.
A ships primary and ready-service magazines
normally stow its complete wartime allowance of
Primary magazines are usually located below the
main deck, preferably below the ships waterline.
Primary magazines must be well-insulated, ventilated,
and have some means of temperature control. They
must also have a sprinkler system that can be activated
from both remote and local stations. Primary
magazines must be closed and locked when
Due to the nature of guided missiles, a fine-line
distinction exists between a missile magazine and a
primary magazine. Most of the differences are minor
and can be related to two factors. First, missile
magazines contain various electrically- and
hydraulically-powered equipment. Quite often, there
is little or no physical separation between this
equipment and the missiles. Therefore, the potential
for fire is great. Fire detection and suppression
assumes greater importance in missile magazines.
Second, missile magazines are located close to their
launchers. This closeness is necessary to reduce
loading time and to support high rates of fire. Thus,
missile magazines are generally located above the
ships waterline. For this reason, missile magazines are
less protected than primary magazines and are more
susceptible to battle damage and fire.
