Closed-circuit SCBAs (rebreathers) recycle the users exhaled air instead of exhausting it to the atmosphere. The exhaled air passes through a canister containing soda lime, which filters out the CO2. The filtered air then goes to a bag where it is mixed with bottled liquid or compressed oxygen. This restores the oxygen content to 21.5%.Respirators NIOSH CDCApr 08, 2020OCCUPATIONAL RESPIRATORY DISEASE SURVEILLANCEOct 22, 2015NIOSH-Approved N95 Particulate Filtering Facepiece RespiratorsApr 11, 2010NIOSH Investigation of 3M Model 8000 Filtering Facepiece Respirators, May 2010This NIOSH guidance document addresses the availability of closed-circuit escape respirators (CCERs) for purchase and the readiness of respirator manufacturers to comply with the provisions in Part 84, Subpart O, of Title 42 of the Code of Federal Regulations.
