A Guide to Atmosphere-Supplying Respirators, cover page publication 2019-174
Atmosphere-supplying respirators provide clean breathing air from a source independent of the work area. These respirators will protect wearers from many types of airborne contaminants (particles, gases, and vapors) and, in certain cases, oxygen-deficient atmospheres. There are three types of atmosphere-supplying respirators: supplied-air respirators (SARs), self-contained breathing apparatus (SCBAs), and combination SARs/SCBAs. Respirators need to be approved by the National Institute for Occupational Safety and Health (NIOSH) Respirator Approval Program and used in the context of a complete respiratory protection program per the Occupational Safety and Health Administration (OSHA) regulation 29 CFR 1910.134, which includes annual fit testing for all respirators with a tight-fitting facepiece.
