NIOSH approves respirator for use against chemical agents

A respirator for occupational use by emergency responders against chemical, biological, radiological and nuclear agents has been approved by the Centers for Disease Control and Prevention's National Institute for Occupational Safety and Health (NIOSH). The Scott Model Air-Pak 4.5 respirator, manufactured by Scott Health and Safety, Monroe, N.C., is a self-contained breathing apparatus (SCBA) that provides users with air from a pressurized cylinder or tank carried on the back. The approval signifies that the product is expected to protect fire fighters and other responders from exposures in the line of duty. NIOSH based its determination on positive results from rigorous laboratory tests, evaluation of product specifications for the device and assessment of the manufacturer's quality control procedures. The action allows the manufacturer to label the approved device as NIOSH-certified for occupational use by emergency responders. The certification for the Scott model is the second approval issued by NIOSH; Spiromatic Models 9030, 6630, and 4530, manufactured by Interspiro USA, were approved last May. NIOSH is continuing to test and evaluate other SCBAs submitted by manufacturers for approval and is developing criteria for approving other types of respirators, such as air purifying devices, for use by emergency responders.
