Check the seal of your elastomeric full face, 4 strap
respirator each time you don the respirator.

1. Positive Pressure User Seal Check

Place the palm of your hand over the exhalation valve cover and
exhale gently. The facepiece should bulge slightly. If air leaks
between the face and the faceseal of the respirator, reposition it and
adjust the straps for a tighter seal. If you cannot achieve a proper
seal, do not enter the contaminated area. See your supervisor.

2. Negative Pressure User Seal Check

Using Particulate Filters
Place your thumbs over the
center of the particulate filters
and inhale gently. The facepiece
should collapse slightly. If air
leaks between the face and the
faceseal of the respirator,
reposition it and adjust the
straps for a tighter seal. If you
cannot achieve a proper seal,
do not enter the contaminated
area. See your supervisor.
