Paddles and
Mod Kits
M42-Series Masks . . .
Hand it through the hatch
sights, take off the mask outserts. That
lets you get your eye closer to the sight.
But remember to put the outserts back
on when you’re finished sighting.
we're a
team!
yeah,
let's
work
together
to keep
each other
healthy

don't
get caught
up a creek
without

paddle

f your M42 mask is going to keep
you in good health, it needs to stay
healthy, too. Follow this prescription
for its good health:
Take off the carrier before you climb
through a tank hatch and hand it out.
It’s tough to wiggle through if you’re
wearing the carrier. You’ll probably
bang the mask against the side of the
hatch. That can break stuff like the
eyelenses or drink tube. If you’re hav-
ing trouble seeing through the tank
The outserts do an excellent job of
protecting the eyelenses. If the outserts
are scratched, they can be cheaply re-
placed. If the eyelenses are scratched,
you’re buying a new facepiece.
Chemical Agent Monitor . . .
Testing the
Tester
I
f the sampler for the chemical agent
monitor (CAM) is not doing its job, it
can mislead you about your cam’s per-
formance. But it’s difficult to tell when
the sampler should be replaced, since
it doesn’t have an expiration date.
Here’s how to tell for sure:
If the sampler doesn’t produce a read-
ing on the CAM, try a known good
sampler from another CAM kit. No
reading? The CAM’s the problem. If
you do get a reading, it’s time for a
new sampler.
If you get no
reading, try
another
sampler
Normally, a sampler should last at
least 10 years.
The H (blister) end of the sampler
has a wintergreen scent. If you can
smell it, it’s good. The G end, though,
has no smell. You can check it out only
with the known good sampler.
Use
outserts
to protect
eyelenses
If you smell
wintergreen,
it’s still good

efective M273 maintenance kits for
the M8A1 alarm are in the supply sys-
tem. The kits contain test paddles that
won’t set off the M43A1 detector. The
defective kits have lot numbers of TG
198E102L001 and TG 198F102L001.
If you find any in your unit, NBC
NCOs, discard the test paddles, but
keep the 10 air filter paddles. Any unit
that got a bad M273 kit will automati-
cally receive 10 new test paddles, but
not filter paddles.
Mod Kits
Free M8A1 modification kits are
available that add tethers to tie the rain
shield and flowmeter to the M43A1
and a jumper wire that lets you silence
the M43A1 horn. You can install the
tethers. But your support will need to
install the jumper wire. Instructions
come with the kit. To receive a kit,
contact Rebecca Morse at DSN 793-
4773, (309) 782-4773, or e-mail:
