Air-Supplying Respirators

Air-supplying respirators are one of two major classes of respirators (the other being air-purifying respirators). This course explains the basics of air-supplying respirators, including the three major types: self-contained breathing apparatuses, or SCBAs; supplied-air respirators (SARS), also called airline respirators; and combination respirators. Topics covered include uses, inspection, maintenance, cleaning, and storage of air-supplying respirators.
