  • Page 11: Description

    Description 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.

  • Page 12: G1 Facepiece

    When in safe atmospheres with no regulator attached, ambient air can be inhaled directly through an opening to facilitate breathing and speaking with minimal resistance. Facepiece Versions ® The facepiece is available with different head harnesses; fabric (both SpeeD-ON and 5-point) or rubber (5-point). G1 SCBA...
