emoval of cadmium fasteners from the Stryker,
or any vehicle, may require sanding or grinding.
Most of the toxic cadmium falls as small pieces
that can be easily cleaned up, but some cadmium
becomes dust.
Cadmium dust on skin, clothing and work
surfaces can be removed by washing—but inhaled
cadmium dust is hazardous to your health!
The risk is great enough to require protective
clothing and respirators when removing cadmium
fasteners. Consult your local industrial hygienist or
safety professional for recommendations.
Some corrosion control experts at TACOM’s
Research, Development and Engineering Center
(TARDEC)
wondered
if
non-toxic
fasteners
wouldn’t be better.
At
point-of-purchase,
cadmium
fasteners
are
cheaper
but
non-cadmium
fasteners
offer
significantly lower life-cycle costs
when you factor in clean-up and
hazardous material disposal costs.
Soldiers can reduce cadmium
exposure by applying the good
word found on Pages 38 and 39.
One of the best ways to prevent
corrosion
is
to
root
out
the
conditions that lead to it. In this
case, TARDEC eliminates the toxic/
corrosive effects of cadmium to
the health of Soldiers and saves the
Army money.
a
little rust on the driver’s hatch periscope thumbscrews can end up being a nightmare.
Those thumbscrews are supposed to make removing the periscope to install the night
sight an easy task. But if they get rusty enough from rainwater and condensation, they
won’t move. Even worse, if you use a wrench to try to unscrew ‘em, they snap off.
Then your mechanic has to drill them out before new thumbscrews can be installed.
And the whole thing starts over again.
If you’ve got stuck thumbscrews, try spraying them with some penetrating Fuid
before trying to loosen them. NSN 6850-00-973-9091 brings a case of 12, 10-oz spray
cans.
Once you’ve got the rusty thumbscrews out, get replacements with NSN 5305-01-
106-7961.

Corrosion
Toxins as a Form of
Corrosion
We’ve all seen
horror movies
of mutated
humans due to
the effects of
toxins
in the
environment.
But, motor pools can be
more of a toxic environment
than we would like, thanks
to
cadmium fasteners.
