4 FHICTIGN HArtHi.s nwi Mum, , v.--.w ,,s-~... ..........--f .-- June 6, 1972 SC.. TO: Members of Asbestos Study Committee SUBJECT: Asbestos Fibers Emissions - Friction Materials A seminar was held at the Illinois Institute of Technology Research Insti tute back in April of this year. Dr. Colin Harwood of IITRI was one of the advisors to the Illinois Pollution Control Board who was ' in favor of the pro posed 1971 regulations as written--that is to include a ban on the" use of asbestos in the brake lining of. vehicles manufactured after January 1, 1975 and sold for`use in'lllinois." - The oages from-the IITRI paper are: pages 22, 25, 26/27, 28, 46, 49, 65, 66, 67, 68, 69, 77, 71, 72, 75. Your Chairman, Ur. I. K. tfeaver, sent this data to me for distribution to the Committee. He commented on the paper: "The main issue I would have with Dr. Harwood's conclusion would have to do with whether or not the free fibers or fibrils released from friction material decomposition are truly hazardous in any way, and I also believe he tends to underestimate the problems in nor>-asbestos containing braking systems.* Your Chairman believes that a meeting of the Committee should be called. I'm asking for a reply on the attached form, for which weeks not; to call a meeting. From this l will try to arrive at a meeting date (perhaps late Jjly or late August). EVJD/lmc E. W.
