Marc Collins -2- October 5, 1976 statement that, "the changing of asbestos brake linings for automobiles was also dangerous because mechanics usually use an air hose to blow out the loose dust after removing the old lining." The implication here is that the brake lining debris that is trapped in the drum contains significant amounts of asbestos that can become airborne after being blown out of the drum by the air hose. This too will be touched upon shortly. Exhibit 1, copy attached, is an abstract along with the reference* _ regarding brake lining decomposition products. Mr. Lynch, the yuilior, was a member of the U.3. Public Health Services when he presented, his finding in May, 1968 that the high temperatures involved l'n broking , converts asbestos to other minerals and that the very small amounts: of. free fiber appear to be an inconsequential health hazard,5:, j ` \ \,'V. ' i Exhibit 2 Is an abstract of a submission made by Caterpillar Tractor Company to the Illinois Pollution Control Board on* October 19 ,ji 1971 as its documented argument against the banning of ashastbs^ontalning friction materials. Beginning on Page 13, a section .titled "B. Brake Wear Products" is pertinent to our present discussion. .Here, Caterpillar draws information from Mr . Jerepflah Lynch ;wh*oVpublis|ied' an article in the Air Pollution Control Association Journal entitled "Brake Lining Decomposition Products". (This may have; been partt?6f the study referred to in Exhibit 1, but the findings ai^*i?Eportdd;,in'greater detail.) The gist of the article is that little ot. no free-,asbestos is present in the dust taken from drums and only inalghificaht.amounts of asbestos may become airborne during braking operations. (Incidentally, we do not know if there even was a page,14:in thijB presentation. The contijr^jity of the thought content suggests' that* there never was a page 14 -- that an error occurred in numbering the pages.) Exhibit 3 is an EPA supported, long term project that was presented in May, 1973. The most infofmative figure from this comprehensive article is that less thanjO,3% o^aabebtos fiber originally present may be emitted to the atmosphere .''during brake life, the remainder will have been con verted to other, mineral produc to. The inWmation.presented in the three exhibits leads me to the inescapably conclusion that if there were significant amounts of free asbestos generated during braking that both OSHA and EPA would Ijave made all ConCerneCeware of this. On the contrary, all experimental data points to the fact that insignificant amounts of free asbestos is generated ypd eij^hyr.emitted to the atmosphere or trapped within a brake drum and Jthe amount is not large enough to raise the fears of even the most militant'of the anti-asbestos forces. 6*'* . ' far as J. W. Penney & Sons Company is concerned, my thoughts are thit very little, if any, asbestos is released to the air during clutch Engagement, While there may be some dust or smoke- observed during severe FAW 11856
