-1ASLESTPS AWD THE FRICTIO;? MATERIAL INDUSTRY Mr. 1. li. Weaver of Kaybestos-Manhattan, Inc., who serves as Chairman of the Friction Materials Standards Institute Asbestos Study Committee addressed the Annual Membership Meeting of the Institute. Mr. Weaver's address was delivered in Vail, Colorado on Wednesday morning, June 27, 1973. Mr. Weaver's address follows: When Ed (Orlslane) asked me to attend your annual meeting last year, I had to decline, which may have been just as well in view of the confused status of both 0S3A and EPA regulations at the time. This year things are only slightly less confused, but I am glad to be able to be here anyway to attempt to fulfill my responsibilities In reporting to you as your Asbestos Study Committee Chairman. Rather than present e detailed statement covering Committee activities for the year, 1 should like to use my time to review some of the more controversial and confused elements of the Federal Asbestos Regulations, and give recommendations as to what 1 think the stance of the Friction Materials Industry should be In regard to them. In lieu of a detailed report covering the past year's activities, I have prepared a page and a half summary of the Committee's work from June '72 thru June 1, 1973. Mr. Drlslane will circulate copies of this summary to anyone who may be Interested la It, and if any of you have questions or recommendations concerning our past work or future intentions, please feel free to bring them up here, or If you prefer, transmit them to Ed for our review later. Probably the single moat significant event that occurred during the pest year on the subject of asbestos hazards was the masting of the International Agency for Research on Cancer that was held at Lyon, France last October. This meeting was attended by more than a hundred and thirty medical researchers and representatives of government, industry and labor from virtually every major asbeatoa consuming or producing country In the world. For four days intensive sessions on asbestos were held by three different panels, each made up of ten to twenty-five of the foremost medical and scientific experts operating In the various fields of asbestos-health research. Following the meetings the committees Issued a coablned report on asbestos cancers. I think the following five Items summarise their moat important conclusions: (1) All major commercial types of asbestos can cause cancer. (2) evidence suggests that excess lung cancer Is not detectable when occupational exposure has been low. (Just what is meant by ''low11 was not stated.) * EXHIBIT 14.1 FMSI 00082 T TT" -2- Aabeatos and The Friction Material Industry (cont'd) (3) Evldenca has been greatly strengthened that all commer cial types of asbestos except Anthophylllte may be respon sible for mesothelioma. (Risk Is greatest lth Crocidolite, less with Amcsite, and apparently still less with Chrysotlle.) (4) Cigarette smoking is an important factor enhancing lung cancer risk in asbestos workers. (5) Surveys of occupational groups have shown a small excess risk of types of cancer other then bronchial and mesothellal, especially those of the gastro-intestlnal tract. The most important item here is the incrimination of all major types of asbestos as causal agents for carcinoma, particularly mesothelioma. Most of the other items only comflrm or substantiate previous conclusions. Sines most of us use substantial amounts of Chrysotlle asbestos in our formulations, association of this material with mesothelioma and other types of cancer is of serious concern. A number of individuals who attended the IRAC meetings cans away with the definite impression that government recognition of asbestos hazards has been accomplished and henceforth should he taken for granted. We can now lode to the next major effort being geared toward worker educa tion regarding occupational health hazards. The Occupational Safety and Health Act requires information ba given by employers to workers concerning the degree of their exposure along with instruction in ways for minimizing exposure. Therefore, it is Incumbent on allemployers whose workers handle or coma in contact with asbestos-containing materials to provide some kind of instruction or training to educate the workers concerning potential hazards and means of avoiding them wherever possible. Accordingly, it would be prudent for all friction materials manufacturers to develop programs to assure adequate com munication with their employees regarding asbestos dust hazards, and \ to inform them of monitoring rasulta, good work practices, and their rasponsibllties in complying with OSHA regulations. If such measures are not taken promptly and properly by management, industry will leave itself wide open for Intense, and in my opinion justified, criticism by organised labor, as wall as potential severe enforcement action by government, and attack by any number of social and environmental activist organizations. If ws don't do this ourselves, be assured that somsona slss will jump on the bandwagon and do it in a way that will not be to our benefit. We can expect more and more activity by organized labor toward educating and training workers regarding health and safety problems and in pointing out to workers what their employers' responsibilities are concerning these matters. FMSI00083 "T -3- Aibctto* and The Friction ! late rial Industry (cont'd) llany union activists are really furious with government's failure to pursue the provisions of safety and health regulations to the letter, and there appears to be a good opportunity for Industry to release reliable Information concerning asbestos hazards both to their employees and to their customers before more Inflammatory Information of this type Is aired in the media under organised labor's banner, these rules and regulations pose much more severe problems for other segments of the asbestos Industry, particularly asbestos textile manufacturers, than they do for most friction material manufacturers. I have been Involved In asbestos products manufscturlng for over twentyfive years and have visited dozens of plants and am aware of only a few friction materials products manufacturing operations that I consider to represent major problems In achieveing conformance to either OSHA or ETA requirements. Including the 2 fibre par cc thareshold limit value. Since significant polarisation may be expected always to exist between management and labor and between management and environmental groups concerning asbestos-health subjects, and since control or conformance to both EPA and OSHA regulations appears to be generally feasible, as far as friction materials are concerned, my recommendation to friction material manufacturers Is that they proceed as rapidly as possible towards confotmance with the regulations. Also I reconnsnd avoiding inclinations to misinterpret provisions where the intent of tha regulation Is clear, but the wording may be subject to question. There has been considerable disregard of a nuaber of provisions mainly In the areas of labeling, monitoring, employee education, personal pro tection, waste disposal, and use of warning signs by segments of asbestos products manufacturing, and I believe this applies to friction material to some extent. One of the most obvious Items has to do with Industry's reluctance to accept asbestos products labeling as required by OSHA. There has been much advertising of asbestos textile products citing the benefits of treatments or coatings that purport to loch the fibre Into the product in such way that It cannot bacons airborne during use. While these claims probably are true to varying degrees depending on the nature of the product, ite uae, and tha way In which It is handled, I do not think this claim Is at sll applicable to friction materials. I know of no way any of ue can be absolutely sura that his friction products, regardless of whether they are aold as original equipment or on tha replacement market, will not be subjected to additional operations or alterations in tha field that could result In sxcesslve exposure of workers or bystanders to sliborne ssbsstos fibre. I have been appalled to learn of a lumber of Instances where this problem baa occurred, and soma of these coats Involved people that certainly might have been expected to know better. FMSI00084 -4- Asbestos and The Friction Material Industry (cont'd) If this kind of thinp, occurs in fabrication operations of major OE customers, it appears to me there can be no argument about the need for educational measures to reduce chances of unnecessary exposure during grinding, drilling or cutting operations. To those who argue that labeling or other types of warning need not apply to replace ment materials because fabricators or appliers handling replacement quantities are exposed relatively intermittently, I say emphatically this just ain't necessarily so! Largs volume replacement users present major potential hatards, and even small Job ahopa can needlessly expose people to high fibre concentrations if operations are performed without controls. That these may be intermittent and of short duration does not preclude possibility for occurrence of adverse health effects in hyper-susceptible individuals, or in less sensitive Individuals who may receive exceedingly high doses of short duration but who may be smokers, or who may experience effects because of synergism with other materials to which they may be exposed either at work or elsewhere. To me, labeling ell containers or packages of asbestos-containing friction material is the very leaat the Industry can do to fulfill morsl obligedon to its customers, their employees, and the public and at the same time conform with minimum requiremanta of the Occupational Safaty and Health Act. I seriously question whether mere labeling is enough to fulfill this requirement. It has been suggested by others as wall as myaalf several times in the past that additional instructions, of a more comprehensive nature than is practical to provide on e label, be inserted inside each package where s possibility exists that ths product might ba used in such manner that an airborne dust problem could bo created. A number of responsible asbestos products manufacturers already axe following this procedure, end there Is a good possibility that it may be made mandatory in future regulations. Adoption of these measures by Industry would show good faith toward compliance and should reduce poeslbilltlas of future criticism by consumer protection groups. I doubt very much that It would have any significant effect on sales or consumption of asbestos friction materials. I know of no substitute for asbestos In normal automotive friction material service, and I know of little or no noticeable efface labeling has had on other products where cautionary labeling has bean used thus far. Keep in mind that NIOSH and the OSIIA Advisory Committee recommended a much more severe label than the one ve are talking about. This subject was heatedly debated during the OSHA Advisory Committee deliberations, and their final recommendation called for use of the word "Danger" Instead of "Caution" and specifically mentioned that breathing asbestos causes cancer. Very frankly, I was exceedingly T- ir FMS/ 0008S -5 Asbestos and The Friction Material Industry (cont'd) surprised when the final QSiiA Standard cane out In favor of consider ably milder working. !! 1 am perplexed that Industry resits the OSHA labeling requirement as virgorously as it does. tlany other elements of the OSHA Regulations came out more favorably toward industry then the recoanendationa that were submitted by NIOSE and the Advisory Committee! and stiff resistance by Industry will be needed to prevent OSHA from strengthening the regulations in months to cons. Us can expect considerable effort to be made by anti-industry elements of the medical profession, by organized labor, and by environmental groups who want the airborne standard lowered from 2 fibres per cc to 1 fiber per cc or even less. Some individuals even speak of asbestos in terms of zero TLV, which, of course, is completely Impractical and would result in virtual banning of mining and use of asbestos for anything. Another controversial subject is fibre monitoring. This is pretty much of e disaster area because of lack of confidence in the membrane filter method for sampling and analyzing for airborne asbestos. Much of this problem Is attributable to the nature of the operation, which Involves considerable judgement in addition to tachnlcal competency on the part of the people performing the teats. Even when performed fay practiced individuals under the beat possible conditions, the method la subject to vide variations in results. Heedless to say, when performed by relatively inexperienced personnel under the widely varying conditions that exist in the field and between different laboratories, results can be extremely variable. In my opinion, the method is not at all suitable for enforcement purposes, but can be used to good advantage by industry for policing its <wn operations and for determining where to devote control efforts with maximum advantage or potential for Improvement. In spite of Its deficiencies, I think the menbrana filter nethod will persist for quite some time, but X will not be at ell surprised if future emphasis by OSHA shifts toward work practice regulations rather than monitoring to e numerical standard. Another controversial item has bean the protective clothing - require ment. This has created considerable question and controversy, particularly In the textile industry where calling limits are difficult to control on certain operations. Different OSHA regional offices have applied different interpretations to the protective clothing requirement, and it's hard for me to see how some of them can be as liberal on interpretation as they are. The regulation specifically calls for full body cover Including gloves, hat, and foot covering, where levels exceed the celling FMSI 00086 x -6Asbestos and The friction Intacta! Industry (cont'd) limit. In spice of this, certain OSEA regional offices take the position that any protective clothing, even as scanty as a short sleeves shirt and trousers, is adequate, provided this clothinp, is changed before the employee leaves the plant. Personally 1 believe this lenient interpretation provides effective protection for most exposures, and I concur that the important thing is to make sure the employee doesn't take the contaminated clothing out of the plant. Other OSHA offices stick to the letter of the requirement, which creates a major problem on many operations *Aere discomfort from full cover clothing can have a very significant effect on operator efficiency. Thia requirement is under vigorous attack by companies that are having problems with it. lo doubt some judgement by the Occupational Safety and Health Review Consaissios or the Federal courts will be forthcoming concerning this element of the regulations, and it is to be hoped thet future revisions of the rule will permit' more flexibility dies the existing wording does. Waste disposal has created problems with both OSHA nad EFA regula tions, and some friction material manufacturers already have extensive facilities in the works to cope with these prc&leras. Of particular Interest is the pelletization of friction material waste to reduce dust to a form that avoids necessity for bagging or otherwise containerizing tho material. This also reduces or eliminates generation of fugitive dust during disposal in landfills. Seversi manufacturers have installed extensive pelletizing systems to solve their waste disposal problems, and this approach appears to be acceptable to both EPA and OSSA as well as stats environmental control agencies. Other approaches have been to utilize wet disposal methods and, of course, some manufacturers ere bagging and labeling the dry waste, * where wet methods or pelletizing axe impractical. Where bags ' or other containers are used for waste disposal, they should be labeled in accordance with OSHA. Medical examination requirements have presented problems, particularly the one of determining wtist constitutes "asbestos exposure". Soma companies have adopted the attitude that all workers. Including office and research people, even though they are not normally considered to be exposed to asbestos, should be included in the medical surveillance program. On the other hand, many seam to follow the tack that anyone exposed to one fibre per cc or less need not be included, tty advice would be to check everybody where there Is any doubt about actual exposure. I could dwell at considerable length on other problems and inconsisof the OSHA Regulations and their various interpretations, but believe 1 probably have expounded on this enough for the moment. Hcxfever, the one main point I want to' get across is that any -7- Asbestos and The Friction Material Industry comparison of the existing regulations with industry's position as stated in their input to the government prior to promulgation of the regulation, and compared with the reconnendatlons of NI0SI1 and the OSHA Advisory Committee, will readily indicate that the existing OSHA standard, with the one serious exception of the two fibres per cc limit to be imposed in 1976, follows Industry's position rather closely. If 1 appear to be defending the present OSHA Asbestos Regulations, it's only because Z am very much aware of how much more strict these rules would be if the reconnendatlons of UIOSII and the Advisory Committee had been followed. I doubt that many in the Industry recognise or realise just how close they may have come to being regulated out of existence. Future occupational safety and health legislation probably will rectify numerous inadequacies in present rulea and may ameliorate some aspects of existing occupational safety and health standards. However, Z seriously doubt that much relaxation if any is to be expected in regard to the Asbestos Regulations. 1 think the industry is going to have to mount e very determined effort to prevent these regulations from being tightened in the future. The EPA regulations concerning anfclent air control of asbestos are another matter. Although it was responsible for initially tagging asbestoe as a hazardous pollutant, since doing so EPA has baan much less diligent In pursuing its announced intentions tward regulation of the materials it declared hazardous. EPA first declared asbestos a hazardous air pollutant on March 31, 1971, and published proposed regulations December 7 of the same year. Hearings were held and much Industry input was accepted and very deliberately reviewed by EPA before they finally issued the National Emissions Standard on April 6 of this year. This regulation was promulgated nearly a year later than called for under the requirements of the Federal Clean Air Act. For this EPA has been under considerable criticism ever since. In addition to being late, the EPA standard is a lot less stringent than I or any otbar industry people, who have followed its develop ment, expected. Hearly ell the objections voiced by Industy concern ing the originally proposed standard were removed before they issued the final regulations. In addition, they modified some requirements to the extant that no one in industry expected, or even would have had the temerity to request, in meetings where these subjects were discussed between industry representatives sad EPA. In essence, the standard bolls down to the following statement as far as emissions are concerned: There shell be no visible emissions to outside air from any asbestos mill or manufacturing operation except when a specified method of sir cleaning, also part of the standards, is used before the emission escapes. In general, the air cleaning systems speciflad, filter asbestoe emissions to the point that visible emissions, other than possible condensed water vapor, would not be produced anyway. ' FMSI00087 T" T -8Asbescos and The Friction l laterial Industry Other requirements concerning use of tailings for surfacing roads, the regulation of demolition activities, end controlled application of spray-on materials are of little concern to friction materials processors. Our biggest concern lies with the emission standard, which will require the tightening up of dust collection facilities end waste disposal practices wherever fugitive dust problems occur. The biggest problem with EPA regulation I have found thus far has been non-uniform Interpretation of what constitutes a visible emission. 1 know the EPA people who drafted the regulation Intended this to mean just what It says. If it's visible under any condition whatso ever, and EPA approved air cleaning systems ere not In use, the emission is in violation. Since most friction materials manufacturers already are employing baghouses that meet EPA standards for cleaning their exhaust air streams. It la unlikely that any severe Impact will occur to the Industry as a whole on account of the EPA regula tions as they now stand. Those few manufacturers who are relying on wet duet collectors that do not meet the EPA standard may have problems. The best vsy to be sure of meeting EPA requirements is to sharpen up on maintenance and operation of existing bagiouse filters and replaca existing wet collectors with baghouse filters to eliminate visible emissions. In summary, the OSHA and EPA Asbestos Regulations are alot more lenient than many Interested and concerned parties wish. We can expect pressure to have them tightened. Friction materials manu facturers should support Asbestos Industry efforts to have them mitigated in hopee they at least aren't made more severe. In the meantime, we should conform to the regulations to protect our employees and our customers and to avoid criticism and enforcement actions. Your Asbestos Study Committee will continue to follow the Interpre tation of existing regulations, the trend of proposed changes, and the development of new medical end scientific study materiel that nay affect future regulation of asbestos products. We welcome your, questions and any lmput you may be able to make concerning our activities. ' FMSI 00088
