ammunition-handling operations are in progress, or by
a ship underway during an ammunition handling
evolution.
7. Ammunition evolutions involving direct con-
tact with ammunition components are curtailed
during local atmospheric disturbances, such as
thunderstorms or high winds. Operations aren't
resumed
until
non-hazardous
conditions
prevail.
8. Stowage of privately owned ammunition and
small arms is permitted aboard ship if approved
by the commanding officer. This type of
stowage is subject to the security requirements
of chapter 700 of the Naval Ships Technical
Manual, Ammunition Handling and Stowage,
NAVSEA S9086-XG-STM-000.
9.
Ships and craft entering commercial or naval
shipyards for periods longer than 6 weeks are
completely
offloaded
of
all
ammunition,
except the small arms ammunition that the
commanding officer considers necessary for
the maintenance of security aboard ship and
inert ordnance items such as bomb fins.
If a ship is expected to remain in the yard for less
than 6 weeks, the ship offloads, as a minimum, all
ammunition or explosives that can't be stowed in
sprinkler-protected or floodable spaces.
10.
The
number
of
personnel
engaged
in
ammunition and explosive handling operations
is limited to the minimum necessary for safe
and
efficient
performance
of
the
work.
Unauthorized personnel aren't permitted in a
magazine, missile handling or testing area, or
at any handling operation involving explosives
or
ammunition.
A
responsible
escort
accompanies visiting personnel.
11.
As a general rule, any pyrotechnic device that
is armed and otherwise prepared for launching
or activating but hasn't been used may be
dearmed, restored to its original packing, and
returned to stowage. The exceptions to this rule
are Mk 25 and Mk 58 marine location markers,
Mk 46 decoy flares, and aircraft parachute
flares. If such devices can't be made safe
beyond question, they must be stowed in
lockers or disposed of according to current
directives.
12.
When the temperature in a magazine con-
taining gas generators, propelling charges, or
fixed ammunition reaches 110°F or above,
certain actions must be taken to preserve safety
and stability of the explosives.
When the magazine temperature is between 110°F
and 120°F, the magazine should be artificially cooled,
as practical. The number of hours and the maximum
temperature reached during each hour of exposure
above 110°F, but less than 120°F, must be recorded.
When the cumulative total number of hours of exposure
to
these
temperatures
reaches
500
hours,
the
ammunition must be expended or turned into an
ammunition activity, stating the reason for return. If the
ammunition was subjected to these temperatures for
less than 500 hours, it should be expended during
subsequent firings.
When the magazine temperature is between 120ºF
and 130ºF, the magazine should be artificially cooled,
as practical. A special record of the number of hours of
exposure and the maximum temperature reached each
hour should be made. When a cumulative total of 100
hours of exposure above 120ºF is reached, prior to a
cumulative total of 500 hours of exposure between
110ºF and 130ºF, the ammunition must have priority for
expenditure or be turned in to an ammunition storage
activity at the first opportunity.
At temperatures above 130ºF, the ammunition
should be removed from the magazine and turned in to
the nearest ammunition activity. When there is no
storage activity immediately available and the ship is in
port, the ammunition may be retained on board in a
segregated magazine or in a ready-service room or
locker. All possible methods should be used to lower
the temperature of the ammunition until the ship is able
to turn it in to the nearest ammunition activity.
