requirements when used properly. However, the safety
features designed in any weapon or explosive
component are only as reliable as the person using
Fuzes are packed in sealed, moisture proof
containers, and should not be unsealed until they are
required for use. Fuzes unpacked and not used should
be returned to their original condition, repacked, and
dated. Once the hermetic seal is broken, these fuzes
should be used before those that are still hermetically
sealed. Mk 376 electric fuzes that have been removed
from their sealed containers and whose shipping caps
have been removed and repacked for more than 30 days
must be disposed of according to current directives.
Additionally, dispose of electric fuzes exposed to
excessive moisture, regardless of length of time.
Fuzes must be handled carefully at all times and
should never be dropped, tumbled, dragged, or thrown.
They should not be struck with a hammer or any tool,
either to open the container or to align them in a
Fuzes should not be packed or unpacked in the
magazine. When a fuze is unpacked, it should be
examined to ensure that the shipping seals are intact
and that the arming stem is not unscrewed. Safety cotter
pins, shipping wires and seals should be left in place
until the arming wire is assembled into the fuze.
Arming vane assemblies must not be bent or distorted.
The hazards of bomb ammunition will vary,
depending on the types and quantities of explosives
involved. Regardless of the particular weapons being
Explosive bomb ammunition is hazardous because of
its tendency, when detonated, to set off all explosive
material that is near it.
Although bomb ammunition containing high
explosives causes greater injury to personnel and loss
of equipment, the improper handling of practice bombs
causes more frequent injury to personnel. When
handling practice bombs, the weight factor alone can
cause severe injury or even loss of limb. Dropping a
practice bomb, even a short distance, with a practice
bomb signal cartridge installed can cause the cartridge
to detonate, resulting in severe and permanent injury to
Accidents are prevented through good design,
testing, and careful handling of ordnance. Safety
precautions must be followed. All personnel involved
in weapons handling must be briefed on particular
safety precautions before actually handling weapons.
All personnel who handle ordnance must be qualified
and certified. Newly assigned personnel, still under
training, are assigned as crewmembers and never
permitted to work alone until they are fully qualified
Specific safety precautions for bomb ammunition
are outlined in the publications for the specific
ammunition and the aircraft loading manuals.
