Atmosphere-supplying respirators (ASRs) provide clean breathing air from a separate source, and protect from a variety of airborne contaminants including particles, gases, and vapors. ASRs can be used in oxygen deficient environments in the form of a pressure demand with escape cylinder supplied-air respirator (SAR) or self-contained breathing apparatus (SCBA).
SARs provide a clean source of Grade D breathable air from either a portable cylinder cart, cascade system, or from a remote source. SARs are used in environments that are deemed too hazardous for air-purifying respirator protection.
SCBAs contain breathable compressed air and are commonly used by firefighters or others who may be exposed to immediately dangerous to life or health (IDLH) atmospheres.
Escape breathing apparatus (EBA) and egress cylinders provide 10-15 minutes of emergency air, and are commonly used in confined spaces. This device is carried by the user as a precaution and in orcer to rescue themselves from a hazardous environment should the need arise.
