2. Make sure all straps,
fasteners, and ad-
justers are in place
and not damaged.
3. Check the facepiece for dirt, cracks,
tears, or holes.
4. Check the lens for cuts, scratches, or
damage which would impair vision.
Squeeze the lens. It should collapse
easily between your fingers. Check that
the lens is secured in the facepiece.
5. Look at the shape of the facepiece for
distortion due to improper storage.
6. Unthread the car-
tridge/canister (if

that the spider gasket,
inhalation valve, and
deflector nose cup are
installed and undam-
aged.
7. Grasp the spider gas-
ket by the raised tabs
and pull it gently out
of the facepiece. The
gasket must be free of

the side voice-mitter
retaining ring. Turn the

the port. The voice-mitter may need
pushed from inside of facepiece to

damage which would let contaminant
enter the facepiece.

tion. The gasket must
