(2)
Inhale so that the facepiece collapses against your face. Hold your breath for 10 seconds. The facepiece should remain
collapsed.
(3)
If the facepiece does not remain collapsed, readjust the headstraps and repeat steps 1 and 2.
NOTE:
If you cannot get a seal by adjusting the headstraps, check the facepiece for leaks. See
Locate the problem and correct it before using the respirator.
Leave the area immediately if any of the following symptoms occur
•
breathing becomes difficult
•
dizziness or other distress occurs
•
you taste or smell the contaminant
•
you experience eye, nose or throat irritation
WARNING!
If you bump or impact the cartridges, leave area immediately and check the security of the cartridge. Perform an Air Tightness
Test before re-entry.
Failure to follow this warning can result in serious personal injury or death.
WARNING!
This device may not seal properly with your face if you have a mustache, beard, gross sideburns or other physical
characteristics that interfere with the face-to-facepiece seal [see ASTM F3387 - Latest edition , Standard Practices for
Respiratory Protection, ASTM International https://www.astm.org/Standard/standards-and-publications.html (ASTM F3387
formerly known as ANSI Z88.2)]. If the facepiece does not seal against your face, non-respirable air can leak into the
facepiece, reducing or eliminating the protection. The face-to-facepiece seal must be tested before each use. DO NOT USE A
FACEPIECE THAT DOES NOT SEAL.
Failure to follow this warning can result in serious personal injury or death.
CAUTION!
•
Return to a safe atmosphere and discard the respirator immediately if the facepiece becomes discolored, crazed, blistered
or cracked, or if other signs of deterioration of the facepiece, motor-blower, filter or battery pack are observed.
•
You can breathe through the respirator with the motor-blower off, but breathing resistance may be noticed, as with a
negative-pressure respirator.
Failure to follow these cautions can result in minor or moderate injury.
5.5
Decontamination
The OptimAir MM PAPR may be used in some applications which may require decontamination of personal and respiratory
equipment before the respirator may be removed. One such application is asbestos exposure decontamination.
Turn the motor-blower off before entering a decontamination shower. The OptimAir MM PAPR still provides respiratory
protection with the motor-blower off, because all air is still drawn through the filter. However, breathing resistance will be
greater than when the motor-blower is supplying air to the facepiece.
5.6
Removing the Respirator
(1)
Return to fresh air and clean the outer surfaces of the respirator before removing the facepiece.
