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.

Sample Video Transcript
Air-supplying respirators provide a source of clean, breathable air that’s separate from the air surrounding the user. The breathable air comes from a tank or compressor, travels through a hose, and is then delivered to a person using the respirator. The person using an air-supplying respirator may wear a tight fitting mask or a hood to provide protection from the hazardous air in the atmosphere. The decision to use a mask or a hood will be based on the hazards present.
