Neck Strap Lock
Obtain a Comfortable Fit
Test for Tightness Before Each Use By One of the Following Methods:
Negative Pressure Method — Place your palms over cartridges lightly. Gently inhale so that the
•
facepiece collapses slightly and hold breath for ten seconds. The facepiece will remain collapsed
while the breath is held unless there is a leak in the seal.
• P100 with Splash Guard Method - Support the cartridge from behind using your fingers and
depress the button with your thumb. Gently inhale so that the facepiece collapses slightly and hold
breath for 10 seconds. The facepiece will remain collapsed while the breath is held, unless there is a
leak in the seal.
NOTE: If a leak is detected, adjust the straps or reposition the facepiece,
ensure the push button is completely depressed, and repeat test until no
leakage is detected.
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 respirator must pass one of the above
tightness tests before the respirator is used.

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 cartridges are the proper type for the contaminant or contaminants present.
