Abstract: In January 1998, OSHA published the final respiratory protection standard, except for the reserved provision on assigned protection factors (APFs). APFs are numbers that estimate the degree of performance of the various classes of respirators. OSHA has developed a statistical model for analyzing available data that will be used to derive APFs.

Accordingly, OSHA will request further public comment on the analyses conducted using that model, the ANSI Z88.2-1992 APFs, the NIOSH Respirator Decision Logic APFs and other relevant methods for deriving APFs. This will assure that OSHA receives and fully considers public input before issuing final APFs. OSHA expects to complete the rulemaking on APFs in 2000.
