WARNING!
Obey the instructions in this section to make sure that the SCBA operates correctly before going

into a hazardous atmosphere.
If the SCBA does not operate correctly as described in this section, remove the SCBA from service.

Make sure an MSA trained and certified repair technician corrects the unsatisfactory condition
before returning the SCBA to service.
If you have a beard, gross sideburns, or similar physical characteristics that prevent direct contact

between your skin and the sealing surface of the facepiece, this device may not seal correctly with
your face (refer to NFPA 1500 and ANSI Z88.2). An incorrect facial seal can let contaminants leak
into the facepiece, decreasing or removing respiratory protection. Do NOT use this device if such
conditions exist.
Do a test of the face-to-facepiece seal before each use.

Make sure the correct nosecup is installed in the facepiece.

Individuals who wear eyeglasses must use the spectacle kit to guarantee a correct fit. Ordinary

eyeglasses cannot be worn under the facepiece.
Only remove the facepiece in a safe, nonhazardous, nontoxic atmosphere.

Wear impermeable protective clothing to prevent exposure to gases and vapors that can poison

by skin absorption.
Failure to obey these warnings can result in serious personal injury or death.
