DONNING
1. To check for facepiece
fit, hold the palm of
your hand over the inlet
facepiece adapter and
inhale. Hold your breath
at least 10 seconds.
T
he facepiece should
c
ollapse and stay col-
l
apsed against your
face. If it does not, re-
adjust the facepiece
and test again.
If this
does not correct the leak, do not use the face-
piece.
2. Test the exhalation valve, take a deep breath and hold
it. Block the inlet facepiece adapter 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.
You may need to exhale sharply to open the valve. If
this does not release the valve, do not use the face-
piece.
This device may not seal properly with your face if you
have a beard, gross sideburns or similar physical
characteristics (see NFPA-1500 and 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 per-
sonal injury or death.
3. Open the cylinder valve
fully. Push in on the
slide button to stop air
flow.
4. Listen for any sound of hissing or popping from the
Audi-Larm Alarm with URC Assembly. If heard, return
the SCBA to an MSA trained or certified repairperson.
