Fit testing and the OSHA standard
29 CFR 1910.134(f) requires a fit test before first use of a tight-fitting respirator, whenever a different facepiece is used, and at least annually; it allows the qualitative (QLFT) and quantitative (QNFT) protocols in Appendix A, which include the saccharin (sweet) and Bitrex (bitter) taste protocols. The FT-10 apparatus, FT-11 sensitivity solution and FT-12 fit test solution are the 3M sweet (saccharin) kit; the FT-30 apparatus and FT-31 sensitivity solution are the bitter (Bitrex) kit; FT-14 is the test hood; the 601 adapter connects a 3M bayonet facepiece to a quantitative fit test instrument.
