3. Fit Check Instructions for APR Configuration
You must perform the following fit check each time
the respirator is worn or before entering the contami-
nated area.
WARNING
If a leak-tight seal is not obtained during
the following fit check, do not wear the
respirator. Ask your supervisor or safety
professional for assistance. The failure
to comply with this warning may lead to
personal injury, illness, or death.
Negative Pressure Fit Check
Cover the inlet of the cartridges and/or filters with the
palms of your hands or another suitable item, such
as a thin sheet of plastic or rubber. When the respi-
rator is equipped with cartridges, filter retainers may
be used as an aid. Alternatively, the cartridges may
be removed to perform the fit check. If removed,
SPERIAN recommends someone other than you
reinstall them after a leak-tight fit is achieved. It
is difficult for the wearer to reinstall the cartridges
without disturbing the face seal and to determine
whether the cartridges are correctly seated against
the facepiece. It is your responsibility to ensure that
the face seal is not disturbed when reinstalling the
cartridges and that each cartridge is sealed against
the facepiece.
Inhale gently and hold your breath to slightly collapse
the facepiece. If air leakage occurs, readjust the
facepiece and head strap, then retest. If filter retain
-
ers are used, do not remove them after the fit check
is completed. Removing the filter retainers may shift
the facepiece and break the face seal.
4. How to Use the Respirator

your respirator, you must read, understand, and

prior to using the respirator.
