Preparing Cylinders For Use - MSA G1 SCBA Operating Manual

When replacing a cylinder valve assembly or after retesting the cylinders, make sure the correct
cylinder valve, burst disc, and O-ring are installed before charging the cylinder.
Determine the maximum service pressure of the cylinder. Fill all cylinders only to the designated
service pressure found on the DOT approval or stamping. For cylinders manufactured under a US
DOT exemption (i.e., DOT-E- #####), consult the exemption, which is available from the Research
and Special Programs Administration (RSPA), US Department of Transportation, 400 7th Street, SW,
Washington, DC 20590-0001.
