P. 0. 5ox 1378 Louisville, Kentucky 40202 .- ' Dear Mr. McCrae: Attached is a copy of our Material Safety Data Sheet on Industrial Vermiculite #1 size. As stated in the M.S.D.S., in dustrial end-users of this material should determine for themselves, whetner they are in compliance with OSHA Regulation 1910.1001 with regard to in-plant exposure to airborne asbestos fibers. It has generally been our experience that where appropriate industrial hygiene practices are followed, exposures are well within the OSHA limits. Should you elect to make such an in-plant survey, we would be interested in knowing what your results were. This kind of end- use input permits us to assemble a picture of end-use exposures with tne product as we are presently controlling. Very truly yours, RCE:M Attachment Quality Assurance Manager Construction Products Division 51 /01a II53721 DU 062023 I n.YTB: *'une 19-7 L'.S. CE- ' ~ E C? LAECT-. Occupations!

OSHA Regulation 1910.1001 defines tremolite as asbestos. Some forms of tremolite are platy. other forms can be fibrillated by physical handling to release airborne "asbestos fibers". Regulation 1910.1001 places a limit of 2 "asbestos fibers"/cc; 8 hour time weighted average and a maxi mum of 10 "asbestos fibers"/cc at any one time for airborne fiber exposure. The physical handling given to expanded Vermiculite can release both air borne fibers and nuisance dust. Refer to OSHA Regulation 1910.1001 for ap proved control procedures.
