NIOSH 1981 Aug:12 pages
An evaluation was conducted by NIOSH of the self contained breathing apparatus of the US Divers Company. The units tested were two 30 minute compressed air, open circuit demand units and four 30 minute, compressed air open circuit pressure demand units. The units carried NIOSH/MSHA testing and certification approval numbers. Laboratory tests included evaluations of breathing resistance, rated service time, alarm assembly for the end of service life indicator, and gas flow under 30 minute demand and 30 minute pressure demand conditions. The units were visually inspected. They passed all laboratory tests and the visual inspection. Examination of two of the units showed that the regulators had not been manufactured with a back pressure eliminator as required by NIOSH. The authors conclude that some units are being produced and sold without the required changes to the pressure regulator.
