1. Introduction 2. Breathing Air Quality Standards

1997 and 2004 versions of CGA G-7.1 specified Grade L air for use with SCBA worn in extreme cold because of the Grade L air low moisture requirements of 24 ppm and -65° F dew point. However, the only other requirement for Grade L air was 19.5% to 23.5% oxygen content. Although the low moisture requirement made ABS Steel Plate - Grade A, B, AH36, DH36, EH36 Leeco Grade A:1/4" 4" 48" 120" Up to 480" Grade B:1/4" 4" 48" 120" Up to 480" Grade D:1/4" 4" 48" 120" Up to 480" Grade E:1/4" 4" 48" 120" Up to 480" Grade AH36:1/4" 4" 48" 120" Up to 480" Grade DH36:1/4" 4" 48" 120" Up to 480" Grade EH36:1/4" 4" 48" 120" Up to 480" Grade FH36:1/4" 4" 48" 120" Up to 480"
