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 is developing an approach to devising APFs that involves analyzing available data including data from workplace and chamber studies, where such data are available. OSHA will request further public comment on the analyses conducted using this approach. This will assure that OSHA receives and fully considers public input before issuing final APFs. OSHA expects to complete the rulemaking on APFs in 2001.
