Chemical, Biological, Radiological, and Nuclear (CBRN) Powered, Air-Purifying Respirator (PAPR) Concept

DRAFT FOR DISCUSSION

November 04, 2005

These concepts are being discussed as a means to approve CBRN PAPR and subsequently upgrade existing 42 CFR Part 84 approved PAPRs to CBRN standards.

Since the introductions of the CBRN PAPR concept, manufacturers and users have expressed the desire and need to have CBRN PAPRs available and to upgrade existing 42 CFR Part 84 approved PAPRs to CBRN standards as soon as possible.

The CBRN PAPR and CBRN PAPR retrofit capability should increase the number of emergency responders afforded protection by NIOSH-approved CBRN respirators.

The CBRN PAPR approval process is essentially conducted in two stages. The first stage requires 42 CFR Part 84 approval. Following 42 CFR Part 84 approval, the manufacturer may apply for CBRN PAPR approval. Following both 42 CFR Part 84 approval and CBRN PAPR approval, manufacturers may continue to a third stage and seek approval for CBRN PAPR retrofit kits. The 42 CFR Part 84 approval process remains unchanged. The CBRN PAPR special test requirements are described in paragraphs 1.0 through 4.3.10 below. The CBRN PAPR retrofit requirements are described in the section 5.0.
