TEST FOR TIGHTNESS
THE RESPIRATOR MUST BE TESTED FOR TIGHTNESS BEFORE EACH USE BY ONE OF THE
FOLLOWING METHODS:
Negative Pressure Method – Place your palms over the cartridges lightly.
Gently inhale and the facepiece will collapse over your face, hold you breath
for some seconds. The facepiece will remain collapsed to your face while the
breath is held, unless there is a leak in the seal.
Positive Pressure Method – Place you palms over the exhalation valve cover.
Exhale normally. There must be a slight positive pressure build-up inside the
respirator.
If any leakage is detected around the facial seal, readjust the head straps and repeat the test till there
is no leakage. If any other facial leakage is detected, the condition must be investigated and corrected
before another test is made.
The respirator must pass the tightness test before it is used. The respirator will not provide protection
unless the inhaled air has passed through the proper filters.
Do not enter any atmosphere with this respirator unless you know that:
15. You have read, understood and followed all the instructions and warnings pertaining to the
respirator.
16. The respirator and conditions meet the requirements outlined.
17. The cartridges are the proper type for the contaminant or contaminants present.
18. The amount of oxygen is sufficient to support life (that is, at least 18 percent oxygen by
volume at sea level). Do not use if oxygen concentration sufficient to support life is
questionable
19. The respirator shows no leakage (See Test for Tightness).
20. The filters do not need to be replaced. Discard exhausted filters.
21. You are not colorblind and can distinguish between the beginning and ending colors of the
end-of-service-life indicator (when using Mersorb and Mersorb P-3 respirators only).
FAILURE TO FOLLOW THE ABOVE WARNINGS CAN RESULT IN SERIOUS PERSONAL
INJURY OR DEATH.
