When you're through test-
ing, remember to remove the
alcohol cartridge. If you leave
it in, alcohol saturates the
counting mechanism. Put the
storage cap back on PATS to
seal out dirt and moisture.
Tubes
If the ends of the tubes get
stretched too large for a good
seal, just cut off
1

4
inch of the
ends with a razor blade. But
remember that the tube that
connects to the mask must be
2 inches longer than the other
tube.
T
he M41 Protection Assessment Test System
(PATS) will give you NBC NCOs a true test of your
unit's masks if you remember the importance of puri-
ty. Just a bit of contamination can stop PATS fast.
Purity begins with alcohol.
Use only reagent grade isopropyl
alcohol, NSN 6810-01-382-2904,
in PATS. That's the purest alcohol
available. Drugstore alcohol
clogs the PATS optical system.
That means a trip to repair.
Take off the storage cap only to
install the alcohol cartridge. That
keeps dirt out of the PATS that
can cause problems. Don't let the
cartridge touch anything before
you screw it into PATS. If you
must set the cartridge down, set it
upright on its end so it won't get
dirty. While the cartridge is in the
PATS, put the storage cap on the
alcohol fill capsule to keep dirt
out of the capsule.
