The Occupational Safety and Health Administration (OSHA) is proposing to include the protocol for the abbreviated Bitrex (supreg) qualitative fit test (ABQLFT) in its respiratory protection standard, according to information published in the Federal Register December 26.
The proposed rule (29 CFR Part 1910) would apply to employers in general industry, shipyard employment, and the construction industry. The proposed ABQLFT protocol consists of seven exercises described in the existing Bitrex (supreg) qualitative fit-testing protocol specified in OSHA's standard. However, each of the exercises in the proposed ABQLFT protocol lasts 15 seconds, compared to 60 seconds for exercises in the existing Bitrex (supreg) qualitative fit-testing protocol, according to the information.
This proposal describes the test sensitivity, predictive value of a pass, test specificity, and predictive value of a fail for the ABQLFT protocol, and requests the public to comment on whether this evidence supports OSHA including the ABQLFT in the standard. Comments must be submitted by February 25, 2008.
