5. Canister: Make sure canister is clean. Never try to clean canister by wash-
ing it or using compressed air. Inspect canister for dents, scratches or other
damage.
Assemble Gas Mask as Follows:
Place canister onto inlet port carefully. Hand tighten by turning clockwise to
ensure a good seal against the gasket or facepiece.
DONNING THE MASK
1. Extend all headband straps.
2. Put you chin in first.
3. Grasp the two side straps in each hand, and pull the harness back over your
head.
4. To tighten straps, pull straight back, not out.
5. Adjust straps as necessary to position facepiece.
TEST FOR TIGHTNESS
THE FACEPIECE MUST BE SUBJECTED TO THE FOLLOWING TIGHTNESS
TEST BEFORE EACH USE. Test the mask facepiece for tightness by lightly
placing a palm over the inlet end of the canister. Inhale gently so that the face-
piece collapses slightly and hold breath for ten seconds. The facepiece will
remain collapsed while the breath is held providing the assembly is gas tight. If
any leakage is detected around the facial seal, readjust head harness straps
and repeat test until there is no leakage. If other than facial seal leakage is
detected, the condition must be investigated and corrected before another test
is made. The facepiece must pass the tightness test before the user should
attempt to enter any toxic atmosphere. The mask will not furnish protection
unless all inhaled air is drawn through the canister.
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 oxygen concen-
tration 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 ABOVE WARNINGS CAN
RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
