2. Test the exhalation
valve, take a deep
breath and hold it.
Block the inlet
connection with the
palm of your hand and
exhale. If the exhalation
valve is stuck, you may
feel a heavy rush of air
around the facepiece.
Note: You may need to exhale sharply to open the valve.
If this does not release the valve, do not use the
facepiece.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics (see ANSI Z88.2). An improper facial
seal may allow contaminants to leak into the
facepiece, reducing or eliminating respiratory
protection. Do not use this device if such conditions
exist. The face-to-facepiece seal must be tested
before each use. Never remove the facepiece except
in a safe, non-hazardous non-toxic atmosphere.
Failure to follow this warning can result in serious
personal injury or death.
