Safety Precautions for MSA Self-Contained Breathing Apparatus cylinders

Breathing apparatus cylinders should be fully recharged as soon as possible after use.
Cylinders should not be stored partially charged for two reasons:
If used partially charged, the duration of the apparatus is reduced.
-
The pressure relief device is only designed to protect a fully charged cylinder from the effects of a
-
fire.
For maximum safety, the cylinders should be stored full or at a pressure above ambient but less than
100 psig.
Prior to recharging, cylinders must be examined externally for evidence of high heat exposure, corro-
sion, or other evidence of significant damage.
Additional information of value when performing external and internal inspections of cylinders may be
found in the latest editions of CGA Publication C-6.1: "Standards for Visual Inspection of High Pres-
sure Aluminum Compressed Gas Cylinder", and/or CGA Publication C-6.2: "Guidelines for Visual
Inspection and Requalification of Fiber Reinforced High Pressure Cylinders" available from the
Compressed Gas Association, Inc., 1725 Jefferson Davis Highway, Suite 1004, Arlington, VA 22202-
4102.
If there is any doubt about the suitability of the cylinder for recharge, it should be returned to a certified
hydrostatic test facility for expert examination and testing.
Always check to be sure the retest date is within the prescribed period and that the cylinder is properly
labeled to indicate its gaseous service. New labels are restricted items which are not available except
through certified hydrostatic test facilities.
When replacing cylinder valves or after the retesting of cylinders, make sure the proper cylinder valve,
burst disc, and o-ring are installed prior to cylinder recharging. Establish the service pressure of the
cylinder. All cylinders that are not 3AA type shall be filled to the designated service pressure only (as
found on the DOT approval label or stamping). For cylinders manufactured under a U.S. DOT exemp-
tion (i.e., DOT-E-####), the exemption should be consulted and is available from the Associate
Administrator for Hazardous Materials Safety, Research and Special Programs Administration,
U.S. Department of Transportation, 400 7th Street, SW, Washington, D.C. 20590-0001.
