Occupational Safety and Health Administration June 25, 2009 – Federal Register Recent Federal Regulation Documents

After thoroughly reviewing the comments and other information available in the record for the proposed rulemaking, OSHA decided that the abbreviated Bitrex[supreg] qualitative fit test is not sufficiently accurate to include among the qualitative fits tests listed in Part II of Appendix A of its Respiratory Protection Standard. Therefore, OSHA is withdrawing the proposed rule without prejudice, and is inviting resubmission of the proposed fit test after conducting further research to improve the accuracy of the protocol.
