JANUARY 26. 1972 A brief review was read of the activities at the Occupational Safety and Health Administration (OSHA) session held in Washington on January 26, 1972. Mr. Matt Swetonic of J-M attended this session, and the Secretary summarized what Mr. Swetonic had told him as follows: OSHA previously had emphasized safety - now the emphasis is on health - five industrial substances are under attack (asbestos, silica, lead, cotton dust and carbon monoxide). Our immediate WV-06015 Winutes of Asbestos Study Committee Most Ing February 10, 1972 concern is asbestos. OSHA is suggesting voluntary set-up of industry committees working with trade assoc is t i ot*. industry repre&er.ta.t )ss indicated that cooperation should be baseo on reasonable standards. The proposed standard is 5 fibers/cc (OSHA is apparently considering reducing the standard to 2 fibers/cc). ASBESTOS EXPOSE STANDARDS The proposed standard by OSHA is now 5 fibers per cc. A fiber must have a 3/1 length/diameter ratio, with the length 5 microns or greater to be considered a fiber. This size can be screened with the optical microscope. Dr. Jacfco noted that there were studies concerning asbestos fibers in the less than 5 micron length by electron microscopy. The British Asbestos Regulations of 1969 were discussed. They have a concentrat ion of less than 2 fibers/cc (sampled over a 10 minute* period) as being satisfaciory, with allowances on 2 to 12 fibers/cc (sampled over a 4 hour period) depending on how much the sample exceeds the 2 fibers/cc limit. See copy of pages 4-5 of Control & Safety Guide 8. At 32 fibers/cc, the plants could be shut down. For reference: The Asbestos is Research Council.

British rareriQiv materials councjl Tha Secretary advised that the British Council had submitted comments to the Ulino is Pollution Control Bozrd and had indicated (through Mr. Bob Gibson of Mintex and Mr. Harry Jones of Ferodo at SAC January .meoi-itfig) their .interest in being informed on the status of asbestos regulations in the ItS, Upon motion duly made, seconded and unanimously passed, it was RESCXVED: to inform the British Council of all regulations known to the Friction Materials Standards Institute, and to forward minutes of our meetings to the British Council. LIAiSQj'i WITH ASBESTOS INFQRMATJQN _A$SQCIAJ ION OF NORTH AMERICA (MA/WO it was noted that Mr. Matt Swetonic, now with Johns-ManviHe, will become Executive Secretary of the AIA/NA. It was recommenced that the FMSi maintain contact with the A?A/h'A concerning any matters involving asbestos in brake linings, asbestos in the work-place,etc. -2- Minutes of Asbestos Studyl*mmittee Meeting *<'/ * February 10^.1972 ' OCCUPATIONAL SAFETY AND 'HEALTH ADM 1HISTfiAT1 ON (OSHA) Mr. Weaver discussed some of the background for the proposed OSHA Standards for Exposure to Asbestos Dust. Proposed rule making for these standards appeared in the Federal Register of December 7, 1971 and January 12, 1972. (Copies were distributed by the Institute by mail to members of* the Asbestos Study Committee) Mr. Weaver is the Industry represeniafive on the Advisory Committee for Asbestos Standards set up under the Occupational Safety and Health Act. He advised that while the*proposed standards are for 5 fibers/cc time weighted average airborne concentrat ion of asbestos dust, the others on the Advisory Committee may push for 2 fibers/cc. OSHA will apparently enforce these regulations and if experience .in related safety enforcement is any criteria, fines or plant closings may be used for enforcement purposes, tfhile it is currently too late to present written comments, the hearings are to be held on March 14, 1972 in Washington. In order to be heard, a person must filo a notice of intent ion to appear no later than March 3, 1972. The not ice must state name, address, approximate time required for presentation, and a statement must be included indicating the position to be taken by the individual. The Chairman and Mr. Reiize indicated that these OSHA regulations were now of prime importance to manufacturers of asbestos brake linings > and clutch facings, and the Secretary was directed to inform the membership concerning the proposed standards. ENVIRONMENTAL PROTECT ION AGENCY (ERA) The EPA5s emphasis in their proposed emission standards for asbestos did not use numerical limits on airborne asbestos, but concentrated on filters and collectors - control practices-; While these are important to all manufacturers of asbestos brake linings, they are practices and standards which, at this time, seem reasonable. The OSHA Standards are the more invnediate problem, ENVIRONMENTAL PROTECTION AGENCY - EMISSIONS FROM ASBESTOS BRAKE LININGS Dr. Jacko advised that the Bendix Corporal ion's studies for the ERA on emissions from brake 1injngs may not be complete on schedule, and that Bendix had requested a time extension on this work that would move their final report back into the fall of 1972. Dr. Jacko indicated that the maximum asbestos fiber in brake lining debris is running about \%. STUDENT PAPER - Bia.QQlCAL EFFECTS OF ASBESTOS ON THE HUMAN ORGANISM Copies of a term paper by Miss Beth Krull, Chemistry Junior at Mundelein College in Chicago wore distributed to the membership.

(The pacer was forwarded to the Institute by Mr. J. Greeners, President of i-) EQUIPMENT FOR MEASURING AIRBORNE ASBESTOS CONCENTRATIONS Mr. Belize discussed the equipment necessary for measuring asbestos concentre t ions. The test is run with a vacuum pump pulling fibers into a filter which is then examined under optical microscopy. (Mr. Reitze discussed the equipment and procedures in more detail in an afternoon session) Dr. Jocko said that the sub-5 micron asbestos fibers were being examined with electron microscopy. He felt that as far as airborne fibers were concerned, these %ub-5 micron fibers "night be targets of the regulators in the future. Mr. Graham asked whether there were any automatic equipment for measuring the asbestos concentrations - either in existence or planned. It was stated that the PA had made a Request for Proposal for design of equipment for automatic measurement, but apparently they received no response. As of now, optical microscopy with the membrane filter is the only recognized method. ASBESTOS STUDY COMMITTEE - FUTURE COlHSF The members indicated that the Committee should exist for screening and passing on information to the members. They do not feel the Committee should be used as a vehicle to comment directly on regulations proposed by the various Federal and State agencies. Further, it is felt that individual company responses to OSHA or EPA or others {such as 111inois Pollution Control Board) are more effective, particularly those from the smaller monufacturers. Unless directed to prepare responses to government agencies by the general membership, the Committee will not assume this responsibi1ity. 'Some members Tel t that the "Asbestos "Study'Tommi ttee7' would'have to expand beyond asbestos - such as into silica, resinous by-products, etc. As of now, the prime target is to be asbestos, but other materials, if considered of importance to the members, will be studied. Another suggestion*was that the Committee consider a membership survey on the methods for disposing of brake lining grinding dust. The Committee members do not plan on regular meetings, and if the Chairman or members feel a meeting is railed for they will contact the Secretary to arrange the meeting. -4 - Minutes of Asbestos Study Committee Meeting February 10, 1972 OTHER BUSINESS Dr, M. Jacko requested that his name be added to the Asbestos Study Committee mailing list, in addition to that of Dr, Spurgeon. 31 was suggested that other manufacturers of brake linings, outside the membership', be advised of these proposed standards by OSHA. Summaries of the afternoon's presentation by Mr. Reitze will be distributed to the membership, *** Upon motion duly made, seconded and unanimously passed, it was RESOLVED: to adjourn.
