WARNING!
Before entering the hazardous area, the device must be put on. The device must be worn on

the body at all times and not removed while in the hazardous area to avoid electrostatic
discharge in potentially explosive atmospheres.
Before entering the hazardous area, check the complete G1 electronic devices for mechanical

damage including damage to the conductive coatings of the housings.
If the SCBA does not function properly as described in this section, the SCBA must be

removed from service and must be checked and corrected for proper operation by an MSA
trained or certified repairperson before using.
The full face mask may not seal properly with your face if you have a beard, gross sideburns

or similar physical characteristics. An improper facial seal may allow contaminants to leak into
the full face mask, reducing or eliminating respiratory protection. Do not use this device if such
conditions exist.
The full face mask seal must be checked before each use.

A nosecup must be installed in the full face mask.

In order to guarantee a proper fit for those wearing glasses, the G1 spectacle kit must be worn

since ordinary glasses cannot be worn under the full face mask.
Never remove the full face mask except in a safe, non-hazardous, non-toxic atmosphere.

Users must wear suitable protective clothing and precautions must be taken so that the device

is not exposed to atmospheres that may be harmful to it.
Failure to follow these warnings can result in serious personal injury or death.
