Must be fit tested with multiple sizes and adjusted by the individual wearer to ensure a tight seal. The employer’s written respiratory protection program must include procedures for selecting appropriate respirators training employees on proper use and maintenance of respirators monitoring proper use medically evaluating employees fit testing and cleaning, storing in a clean location, inspecting, repairing, removing from service or discarding respirators.Īn air-purifying respirator with a facepiece constructed of flexible rubber or silicone to which replaceable filters for particulates and other chemical hazards are attached.įorms a tight seal over the mouth and nose. When workers are required to wear a respirator, 29 CFR Part 1910.134 requires employers to assess risks, select a NIOSH-certified respirator and establish a comprehensive respiratory protection program. 4įDA tests that must be satisfactorily performed include: 1Īs a medical device, surgical N95s must receive clearance from the Food and Drug Administration requirements in its 510(k) rules. NIOSH certification requirements for all respirators, including filter efficiency performance, are contained in 42 CFR Part 48. Must comply with both NIOSH certification requirements as a respirator and the FDA clearance requirements as a surgical mask: NIOSH publishes a list of approved manufacturers and issues a rescission letter for manufacturers that fail their requirements. The manufacturer’s name and “NIOSH approved” must be printed on the mask.Ĭertification requirements for all respirators, including filter efficiency performance, are contained in 42 CFR Part 48. The National Institute for Occupational Safety and Health (NIOSH) certifies all respirators that are to be worn by workers in the workplace. Protects the person wearing the respirator when inhaling and provides a barrier protecting the nose and mouth from large droplet sprays and splashes coming from patients.Īlso provides a barrier to help prevent exhalation of contamination by the wearer to others in the work environment.
