Dear Half-Mast,
Is there an NSN for the ammo placards required for vehicles carrying ammo
and explosives? We’ve searched and searched with no luck.
SFC W.C.
Dear Sergeant,
NSN 9905-01-371-5231 brings an ammo placard for a bit less than $19. It is a
Fip-type aluminum plate for the various classes of explosives.
Here’s a quick review of the classes:
1.1 explosives:
Consists of explosives that have a mass explosion hazard. A mass
explosion affects almost the entire load instantaneously.
1.2 explosives:
Consists of explosives that have a projection hazard, but not a
mass explosion hazard.
1.3 explosives:
Consists of explosives that have a ±re hazard and a minor blast
hazard and/or a minor projection hazard, but not a mass explosion hazard.
1.4 explosives:
Consists of explosives that have a minor explosion hazard.
The explosive effects are largely con±ned to the package and no projection of
fragments of signi±cant size or range is expected. An external ±re will not cause an
instantaneous explosion of almost the entire package.
1.5 blasting agents:
Consists of explosives that have very little chance of
detonating under normal conditions.
1.6 explosives:
Consists of explosives even less likely to explode
than those in the 1.5 class. They have no mass explosion hazard.
Dear Half-Mast,
Are we supposed
to turn in the
Common #1 and
#2 tools sets to
get the standard
automotive tool
set (SATS)?

Dear Editor,
When you’re through using your torque wrench to tighten
bolts, it’s always a good idea to return its setting back to
zero. That helps the wrench maintain its accuracy.
But that’s especially true if you have the kind of torque
wrench that clicks. The “clicking” torque wrench has an
internal spring. If this wrench isn’t returned to zero after use,
the spring wears out. Soon it’s giving you bad readings.
So zero all torque wrenches, but especially those that click.
For more on tool use and care, see TM 9-243,

Care of Hand Tools and Measuring Tools.
