Cerullo MOTOR 1790 Broadway New York, N.Y. 10017 Dear Mr. Cerullo: I have to Mr. received Drislane a c copy of oncernin gyaousr ~lteetmtbeerro9f September 20 article in the New York Daily News in which Dr. Selikoff is quoted as saying that over 20% of the people repairing brakes on motor vehicles will die of cancer. I wonld very much appreciate receiving a copy of this news story because I am not aware of any scientific studies indicating such a mortality rate. /as cc: Mr. E. w. Drislane/ Mr. I. H. Weaver Mr. R. H. Mereness FMSI 06766 FRictiON MATERIALS STANDARDS INSTITUTE, INC., E-210 ROUTE #4, PARAMUS, NEW JERSEY 07652 1 October 22, 1976 TO: Asbestos Study Committee SUBJECT: Recommended procedures for reducing asbestos dust during brake servicing On September 27, 1976 I forwarded a write-up to Asbestos Study Committee members relative to procedures that might be followed in brake service areas to minimize the problems with asbestos dust. This write-up was made about two years ago and had been reviewed by Mr. Weaver, of Raybestos Manhattan, Inc. and the writer in order to up-date it. However, in the last review Mr. Paul Lee of Raybestos suggested "Recommended Procedures for Reducing Asbestos Dust during Brake Servicing." A copy is enclosed. Mr. Lee, and Mr. Weaver concurs, that this "Recommended Procedures for Reducing Asbestos Dust during Brake Servicing" is more concise and to the point as concerns procedures to be used in brake service areas. It is also more in harmony with the NIOSH recommendations. It is suggested that the Institute endorse such a write-up, or review the existing draft procedures that might be recommended to brake service-~shops .when working with asbestos containing brake linings. I suggest that you review this one page write-up and compare it with the earlier write-up and perhaps review it along side of the NIOSH recommendations. The Institute would like to prepare a final write-up in this area that could be used for distribution when questions are received from the news media and others interested in the asbestos problem. E.

J. 07652 BULLETIN N O. 5 8 1 October 12, 1976 CONTROL OF AIRBORNE ASBESTOS CONCENTRATIONS IN THE WORKPLACE-- INDUSTRIAL TYPE VACUUM CLEANERS Over the past many months, without de-emphasis on problems in the factory area, those in favor of stringent regulations on the use of asbestos have targeted friction materials servicing--particularly brake lining service-as a potentially hazardous area. Technical papers in this area have not based observations on the OSHA standard's 8 hour time weighted average for fibers greater than 5 microns in length. Most papers have emphasized peak concentrations (as blowing brake lining dust from a used brake awaiting reline) and the fibers shorter than 5 microns in length. Based on discussions at the Asbestos Information Association meeting in September, efficient vacuum cleaning systems should be of help not only in the factory but in the brake service area. I have, therefore, enclosed sales literature from two manufacturers, along with the NIOSH (National Institute of Occupational Safety and Health) recommended procedures for asbestos brake and clutch servicing. Before distributing this information, 1 reviewed this data with Mr. 1. H. Weaver, acting Chairman of our Asbestos Study Committee, to be sure this information was worthwhile. He concurred that the following information was worthy of distribution to the membership: 1. NIOSH Recommended (Interim) Procedures for Asbestos Brake and Clutch Servicing 2. NlLFISK literature 2.1 NILFISK absolu<i:e filter 2.2 NILFISK manometer 2.3 Dust free disposal 3. T8MPO Brake and Clutch Service Vacuum This literature is being enclosed (one copy to each member) with the mailing to: EWD/erc E. W.

Due to preliminary data demonstrating significant asbestos exposures during presently used brake and clutch servicing techniques. NIOSH has reviewed alternate techniques whereby asbestos exposures are reduced. The follow~ng are interim procedures recommended by NIOSH to minimize dust exposures. 1. If possible, an area shall be designated for all brake and clutch repairs. Entrances into this area shall be posted with an asbestos exposure warning sign as follows: Asbestos Dust Hazard Avoid Breathing Dust Wear Assigned Protective Equipment Do-Not Remain in Area Unless Your Work Requires It Breathing Asbestos Dust V~y Cause Asbestosis and Cancer 2. During brake servicing, an air purifying respirator, either single use or with repla~eBble particulate filter(s), as a~proved by the Mining Enforcement and Safety Adminisfration (formerly Bureau of Mines) or NIOSH. shall be worn during all procedures starting with the removal of the wheels and including ~eassembly. During manual clutch servicing, such a respirator shall be worn during removal and cleaning of the clutch, pressure plate and housing assembly and during installation of the new clutch assembly. 3. Dust shall first be cleaned from brake drums, brake backing plates. brake assemblies and clutch assemblies using a.n industrial type vac'.lum cleaner equipped witn a high efficiency filter system (>99% efficiency for 0.3 ~m diameter aerosols). After vacuum cleaning, any remaining dust ehall be removed using a rag soaked in water and wrung until nearly dry. Under no circumstances shall compressed air or dry brushing be used for cleaning. 4. During arcing and riveting opera~ions. an approved respirator, as described in (2) above, shall be worn. Grinding (arcing) machines shall be provided with lotal exhaust ventilation such that worker exposures are maintained at least belo~ the 1976 OSHA asbestos standard (29 CFR 1910.1001).* At a minimum, the dustbag of the arcing machine shall be removed and replaced with the hose of the. high efficiency industrial vacuum described in (l) above. FMSI 06769 '' -2- 5. Industrial vacuum cleaner bags containing asbestos dust and cloths used for wiping brake and clutch assemblies shall be sealed in plastic bags and labeled with the following warning label printed in letters of sufficient size and contrast to be readily visible a~d legible; Caution Contains Asbestos Fibers Avoid Breathing Dust .Breathing Asbestos Dust May Cause Asbestosis and Cancer All asbestos waste shall be disposed of in accordance with the OSHA asbestos regulation, 29 CFR 1910.1001(h). During removal of vacuum bags. an approved respirator, as described in (2) above, shall be worn. 6. All floor cleaning in areas where brakes and clutches are repaired shall be done with the high efficiency industrial vacuum cleaner as described in (3) above. Grinding (arcing) machines shall also be cleaned with such a vacuum cleaner and.any remaining dust wiped with a damp cloth. An approved respirator, as described in (2) above, shall be used during this cleaning. 7. Although adherence to the ab~ve procedures should minimize any contamination of workclothing, it is required that the appropriate portions of the OSHA regulations on asbestos (29 CFR 1910.1001 (d), {3 and 4)) concerning special clothing, change rooms, etc. be followed. NOTE: Strict adherence to the above procedures ~hould minimize exposures to mechan~cs during brake and clutch servicing. These are interim recommendations and are subject to revision pending results of ongoing NIOSR research. Section 1910.1001 of the Code of Federal Regulations vas fo~rly Section l910.93a. This change was noted in the Federal Register, May 2.8, 1975.
