WARNING!
• If you have a beard, large 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, Standard on
Fire Department Occupational Safety and Health Program, and ANSI Z88.2, Practices for Respiratory Protection). 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 negative pressure seal test before each use and before going into a toxic atmosphere.
• Make sure that the correct nosecup is installed in the facepiece. Refer to the G1 APR Approval Insert (PN 10160485) for
information about approved configurations.
• Individuals who wear eyeglasses must use the G1 spectacle kit to guarantee a correct fit. Ordinary eyeglasses cannot
be worn under the facepiece.
• Wear impermeable protective clothing to prevent exposure to gases and vapors that can poison by skin absorption.
• Only remove the respirator in a safe, nonhazardous, nontoxic atmosphere.
Failure to follow these warnings can result in serious personal injury or death.
Make sure that the APR adapter and applicable air filtration cartridges/canisters are installed before you don the respirator.
When the respirator is adjusted correctly, the user should not taste or smell the contaminant, or feel irritation of the eyes, nose,
or throat. The user's inhalation resistance should be as experienced during training.
