Gypsum cuebec Asbestos Mining Association St. Luke's Hospital, Cleveland Davies, Hardy, Loeb, Austin & Ives The meeting was called to order by the Chairman, Mr. James A. Main. The minutes of the last meeting of the Council held on Kovenber 14, 1568, which had been previously mailed to all members, were upon motion duly made end seconded unanimously approved. _* Mr, Cemy delivered the Treasurer's report and stated that the present balance of the Council is $5p0.01 Mr. Cerny*s report was accepted. Mr. Cerny also prepared'e budget for the calendar year 1969 as follows: Miscellaneous Expenses, including travel Administration Legal , .* 500. 1 000 2,000. $3,500. Mr. Cerny stated that meets nr. expenses are to be borne by members on a pro rata basis, printing expenses, if any, are r to be borne on & pro rata basis and, therefore, these expenses were not included in the budget. Mr. Ceroy proposed that each member company of the Council be assessed $350 to provide for . the I969 budget. On motion duly made and seconded, the budget was unanimously approved as submitted. The Chairmen, Mr. Main, then polled each member company for its approval of the $350 assessment. All members polled agreed to the assessment. Kr. Main spoke briefly on the background of the concer in the asbestos industry with health and safety practices. He noted that the Asbestosls Hesearch Council in England has alread developed four Recommended codes of Practice entitled: (1) For Handling, Working, end Fixing of Asbestos and Asbestos Cement Products in the Building end Construction Industries; (2) On .tfFreeautidstt to be taken when Cutting, Drilling or Machining Asbestos Cement and Asbestos-based oar& in the Shipbuilding Industry; (3) For Handling Consignments of Asbestos Fiber in British Ports; (4) For Handling Asbestos Fibers use.d In Thera* Insulation. Copies of these Codes were distributed to the members in attendance. Mr. Main also referred to the technical note prepared by the Asbestosls Research Council entitled "The Measurement of Airborne Asbestos Dust by the Membrane Filter Method1*. Copies of this technical note were distributed to members in attendance. Mr. Main also referred to the menorandui on Dust Sanoling and Counting dated December 9, 19*6 prepared b: M. Lachance', Dust Control Engineer of the Quebec Asbestos Minin Association. Copies of this memorandum were also distributed. Mr. Main noted that there had been dnveloonent. subseouent *0 the meeting of the Council held on November 1U, 3.06S In'particular, he referred to the speech by Dr. Selikoff at the Dalles meeting of the American Association for the Advancement of ..Science.; the study program of the Institute for Occupational and Environmental Health in Montreal supported by QAMA and the studies of the Industrial Hygiene Foundation. Kr. Scheekler reported that no progress had been mad< on the proposed safety manual since the last.meeting of the Council because so many developments had occurred that addi tional time was reouired to assess them. Mr. Scheekler noted that the American Congress of Governmental Industrial Ky^ienis had reduced permissible particles in its 1969 indistri:! stand from 5 million to 7 million particles per cubic feet of air. stated that Johns-Manville1s goal is 1 million particles per cubic foot. Mr. Scheekler observed that the proposed British ref .tions are becoming morc stringent; that the U. S. Department c the Havy is strongly advocating the wearing of respirators by all men doing asbestos work. He stated that now types of t* ? 4 * 3- respirators are needed because the beet respirators available' aay be satis factory for particulate matter, but they are not satisfactory for asbestos fibers. Hr. scheckler described, to the meeting the membrane filter method being developed by J-M to evaluate the amount of dust their men breathe. A meeting of the subcommittee on the proposed pamphlet will be convened, following this meeting. The members of the Subcommittee on the pamphlet on Recommended Health Safety Practices for Handling and Applying Asbestos Cement Products are: A. . Alpine Harry Messier F. H. Zimmerman C. Scheckler Certain-teed GAP rational Cypsra Johns -KanviUe Some, discussion was held on the purposes and proprle' of issuing the proposed booklet. It was noted that as to asbe: cement siding, there is very little problem in the field, and that the end use of the materials should guide the purposes of the booklet. In particular, it was noted that a differentiation must be made in the two groups that are to be reached by such booklets. One group can be envisioned as consumers and the other group can broadly be called asbestos workers. .* * Mr. Cemy remarked that the proposed booklet was originally ccntenplated,for use anong fabricators end was expected to outline heslth/safcty measures for workers and not necessarily for consumers. Mr. Cer*.y stated that one purpose of Issuing such booklets n health/safety measures would be limitation of liability of the manufacturers. He stated that there-has-ben a tendency for employees to sue their f&brlcato employers as well as the manufacturing suppliers. Xn such sui there is no restriction to the recovery Units of Workmen's Compensation end other manufacturers are often iisn.'eaded as third-party defendants. Mr. Cemy stated that any booklets prepared and issued ,by the Council should be backed with a strong public relations effort that would secure write-ups of interviews and other releases for trade press magazines. fubl` relations efforts should else keep insurance carriers advised of what the industry is doing. Following Mr. Cemy's remarks, the Council authorise Mr. Main to appoint a Subcommittee on Litigation, Legislation and Insurance. Mr. Main will advise the appointees to that Subcommittee directly and will report at the next meeting of the Council. Hr. Zimmerpan reported that there had been no mcetin k- or the Subcommittee on In Plant Eirrironsental Control end tKa* this Subcommittee Mould meet following * the. remarks of pr.

Mr. Main introduced to the Council Dr. George V. Writ Director of Medical Research, St. Luke's Hospital, Cleveland, Ohio. Dr. Wright addressed the meeting on "A Current Assessmer of Asbestos as an Bivironraental Health Problem", {For the benefit of the members in attendance who requested it, there follows a brief summary of the highlights of Dr. Wright's talk. Dr. Wright has reviewed end approved this summary.) Dr. Wright remarked that his appearance before the Council was appropriate because information available to him .. indicates that one-fourth of the asbestos used m the United : States goes into asbestos cement products. He stated that **** although'studies had been made on the biological effects of asbestos fiber when such fiber is not bonded (i.e. textile, milling, mining and Insulation operations J extinction and stud of the effects of such fiber when incorporated'in asbestos ce~e: products would appear to be warranted, considering the volume*' of asbestos used in these products. By way of historical background. Dr. Wright indicated that British Government statistics in the 1530*s provided information showing that S0^ of male workers in Vac asbestos textile trades over a period of twenty years or more had asbestosis. Dr. Wright noted that 95S of particles which pess through human air passages is expelled. By analogy, asbestos fibers probably do the same. Of the fibers remaining in the lung, the human body coats some of these with protein and iron. Because fiber glass and graph*tc particles ore also subjected -5 - to similar phenomenon, these coated particles are referred i""as "ferruginous bodies". After substantial exoosure for twenty years to asbesto dust, 75? of the workers so closed will develop sears betectabl by X-rays* Some workers develop these scars sooner then others* She formation of scars constitutes the disease known as- -- asbestosis. As these scars develop, the pipes through which -- blood flows through the lungs are destroyed. Death can ultimately result. We figures in Great Britain as of 1930 proved that the mortality rate or length of life of textile workers in Britain is shorter. Since then, the life span of such asbestos textile workers has improved because the number of fibers in the air has been reduced. Dr. Wright explained that many lessons had been learne from studies involving silica. As a result of counts made of '*silica particles, and experience that silica particles measuring 5 microns or under in diameter were those that- stayed in the lungs, limits were established of maximum concentration of * .. silica particles in industrial settings as early as 1939* At that time, maximum concentrations were 5 million particles per cubic foot. Dr. Wright outlined the Lynch studies published in 1935 which associated bronchogenic cancer with asbest03s. These studies were fortified by further studies made in Man chester, England in 1950 by Dr. Doll. Dr. Doll's studies identified 11 cases of bronchogenic cancer among.113 workers in an asbestos textile factory. Subseouent studies in Canada done by the Industrial Hygiene Foundation did not duplicate the Manchester re^ultn. Subsequently, studies were done by Drs. SclVnoCt end Hammond among insulation workers* These studies claimed '* that the incidence of lung cancer is 12 times higher among insulation workers than ason3 non-insulation workers. Dr. Wright noted that in those studies no bronchogenic cancer was found among non-smokers. ~ ` Dr. Wright explained in brief outline sore theories of carcinogens and indicated that there are seme who are exploring the concept of co-carcinogens - that is to say, that asbestos fibers and cigarct smoking may act together to become cancer inducing agents. It is knov.n, for example, that bronchial cancer occurs 8 times more* frequently among smokers than non-smokers and SO times more among smokers who are also insulation* workers than among non-smokers who are not Insula tion workers. In passing. Dr. Wright suggested thr.v it might be 4a ' \ -6- possible for employers to limit employment in insulation voi only to non-smoking workers. Pr. Wright explained that the policing of such employment conditions could pose many preet problems. Dr. Wright also explained the findings of certain, studies made among workers in South Africa where a cancerous growth was noted to appear on the outer surfaces of the lung These studies indicated that these cancers, or mesothelioma, occurred among South Africans exposed to crocidolite. He noted, however, that there were differences b^'^een statisbi* compiled in the Transvaal and in the rvorthwes )pe. He else stated that cases of mesothelioma occurred workers as well as among people who live near crocidolite workings (so- called "neighborhood cases"). finally. Dr. V;right sketched some developments beirv -r made in^-studies of gastrointestinal cancer which may indicate the development of cancer following the swallowing of asbesto: particles or fibers by asbestos workers. Or. Yiri^ht explainec that considerable research needs to be done in this field. Sn response to & cuestion concerning proper practice of industrial hygiene and the detection of fibrosis and of bronchogenic cancer, Dr. YJright stated that employers should conduct X-rays of all workers exposed to asbestos every two years commencing before the fifth year of employment in such exposures. Drf tfright also explained scr*e or the difficulties involved in running tsts on sputum samples; statin- that six samples were recuired from each worker in order to achieve a true reading with resard to cancer. After a feu general cues tier* s posed by members of the Council, the meeting adfsurned. Hespectfully submitted. / Eradley yalls*
