TEST FOR TIGHTNESS BEFORE EACH USE
The respirator must be subjected to the Tightness Test before each use by one
of the following Methods:
Negative Pressure Method — Place your palms over the canister(s) lightly.
Gently inhale so that the facepiece collapses slightly and hold your breath. The
facepiece will remain collapsed while the breath is held unless there is a leak in
the seal.
Positive Pressure Method — Place your palm over the exhalation valve cover
lightly. Gently exhale so that a slight positive pressure builds up inside the res-
pirator and hold your breath. The positive pressure will remain while the breath
is held unless there is a leak in the seal.
If any leakage is detected around the facial seal, readjust head harness straps
and repeat the test until there is no leakage. If other than facial seal leakage is
detected, investigate and correct the condition before testing again. The respi-
rator must pass one of the tightness tests above before the respirator is used.
The respirator will not furnish protection unless all inhaled air is drawn through
suitable canisters.
Do not enter any atmosphere with this respirator unless you know that:
1. You have read, understood and followed all instructions and warnings
pertaining to the respirator.
2. The respirator and conditions meet the requirements outlined.
3. The canister is the proper type for the contaminant or contaminants
present.
4. The amount of oxygen is sufficient to support life (that is, at least 19.5
percent oxygen by volume at sea level). Do not use if an oxygen con-
centration sufficient to support life is questionable.
5. Respirator does not leak (see Test for Tightness).
6. Canister does not need to be replaced. Discard exhausted canister.
Failure to follow the above warnings can result in serious personal injury
or death.
