Description

The MSA G1 - referred to hereafter as SCBA - is a pressure-demand self-contained breathing appa-
ratus (SCBA) operating independent of the ambient air for use in atmospheres immediately
dangerous to life or health.
Breathable air is supplied to the user from a compressed air cylinder via a pressure reducer, a regu-
lator and a facepiece. The exhalation air is released directly into the ambient atmosphere.
The integrated personal alert safety system (PASS) provides the user with the ability to monitor move-
ment through a motion sensor. When a user remains motionless for 30 seconds, the PASS device
goes into full alarm to alert those around the user. The PASS device also monitors cylinder pressure
and battery status.
The G1 SCBA consists of the following components:
• G1 Facepiece
• G1 Regulator (also referred to as Demand Valve)
• G1 Heads-Up Display (HUD) (part of both facepiece and regulator)
• G1 Pressure Reducer with low pressure warning device
• G1 Control Module
• G1 Power Module
• Cylinder and Valve Assembly
• G1 Carrier and Harness Assembly
