AirfJL^x, is awar^ tliat asbestos has been classified as a health hazardlCand^QSJJA'iias published standards specifying permissive exptjsure^leyels. These standards are listed in the Federal Registefc'under Subf&rt "Z", Section 1910.1001. Effective July 1;' 1.9the-'standard establishing permissible exposure to aiiibofrie coh.qj.ntrat ions of asbestos fibers, states as follows: 'h a. a) "The 8-hour.time-weighted a'verage airborne concentrations of asbestos fililehs to yjrjiij.h any employee may be exposed shall not exceed two Jiberj';^'longer than 5 micrometers, per cubic c e nt i m e te r-of ar.' b) "Ceilirrg'cowjehtration. No employee- shall be exposed at any timj."'t6 air^pjne concentrations of asbestos fibers in excess j;c>T''10 fibel'sj- longer than 5 micrometers, per cubic centimeter \ of ai^.^'^ifWote: This would be for a shorter duration than the S-houih time element referred to above).. ^ Whe^r,!, exposure levels exceed these prescribed limits, an approved `h./','" .^type^respirator must be used. Apparently, Consolidated Papers, Inc. has some concern 'that these exposure levels might be exceeded during engagement of an Air flex clutch or brake, as particles of friction material.are emitted into the surrounding atmospherg. The following information should help clarify this matter. s FAW 17050
