outlet valve cover and disc, quick doff
hood, universal second skin, and
outserts. Now you're ready to dunk and
wash your mask. Clean the other items
separately.
Outserts
: Make sure both outserts are
in place. If the outserts are scratched,
replace them. If they’re missing and
the lenses are scratched, the
whole facepiece must be replaced.
Outserts also keep the mask from
fogging.
Outlet valve cover
: Take it off and
check the disc for dirt that can cause
leaks or make it hard to breathe. Wipe
out dirt with clean cheesecloth and
make sure the valve seat and disc are
clean and not damaged.
This is criti-
cal for a good seal.
In the field, check
the cover for looseness periodically.
When the hood’s pulled up, it can un-
seat the valve cover.

dry cloth
Canister
: It’s OK for the canister to
have dents as long as they’re no deeper
than 1/4 inch. If they’re deeper or cross
a seam or threads, you need a new
canister.
If you have questions about any of
the masks, call the Chemical/Biologi-
cal Maintenance Hotline at (800)
831-4408 or fax (410) 436-3912, DSN

Don’t use your mask as a cushion.
Your weight can break stuff like the
drink tube. If you must climb in a tank
hatch, take off your mask carrier and
hand it through. Then you won’t scrape
it against the side of the hatch.
Wash-
ing your mask in soap and water
is a great way to clean it. But remem-
ber to first remove the cannister. If it
gets wet, it's ruined! Then remove the
In the Field
Loosen the hood straps as much as
possible before you put on or take off
your mask. Loosen the straps gently,
don’t jerk them. That makes it less
likely the hood will be torn.
Remember, snug is fine for the
mask headharness. If you tighten
the headharness as much as
possible, you’ll give yourself a
tremendous headache, plus
you’ll wear out the harness.
Once you get the harness
adjusted correctly, loosen or
tighten only the cheek straps
when removing or putting on the
mask. The other straps don’t need to
be adjusted again once they’re set.
