NIOSH has issued its first approval of respirators for occupational use by emergency responders against chemical, biological, radiological and nuclear agents. NIOSH approved Spiromatic Models 9030, 6630 and 4530, manufactured by Interspiro USA, Inc. The respirators are self-contained breathing apparatus.

NIOSH is continuing to test and evaluate other SCBAs submitted by manufacturers for certification under the new program for these types of emergency response exposures. Other types of respirators, such as air-purifying devices, used by emergency personnel will also be tested and certified in the future.

Devices being labeled as NIOSH-certified for occupational use by emergency responders does not constitute a commercial endorsement of the products.
