These pick up dust and carry blanket (mucus blanket)-particles deposited on blanket gradually work out the particles from the surface. (Self-cleaning mechanism.) Second cleaning mechanism "macrophase '. Doesn't handle all du3t some does remain. .4. In 1900, men who worked-in textile mills in England had short life and died from heart failure. By 1930, in was known that the physical problems were much higher here than in other trades. In 1940, the "Threshold Limit" was established. This is about the same as for chrystalline silica (all items dose related). Below 5 million particles/ft3, no problem with chrystalline silica proven. However, this is not true of asbestos. When asbestos ~ was originally tested on this basis, it was mixed dust; hanse, must have much less in asbestos particles. At fiist, fiber counts were not made just a count of particles. In 1960-61, fiber counts were made and fiber diameter/length (1/3) to be classed as such in counting. Membrane filters were used . to collect the fiber for counting. Hence, there are safe level3 of inhalation in the working life on an individual. .. British set the "Threshold Limit" at 2 fibers/cc (have<'l% chance of developing fibrosis). Between 4-6 fibers/cc is considered acceptable Between 6-10 fibers/cc is considered unacceptable s^lQ fibors/cc man should not work. U. S. industrial hygienist TLV's abandoned 5 million particles/ft^ and went to fiber counts direct. Set limit of 5/cc peak level. Time weighted average is 5. There are levels which are safe but the levels wore set to protect the most vunerable as some people are more susceptible to fibrosis. ' In about 1948, investigations of death causes of people having asbestosis showed that such people had a higher rate of death from lung cancer. Mining & Milling Vxpoaiira Thera is no evidence that the people in this industry have a greats incidence of lung cancer; however, data on exposure is not too gooc Inspection Workers Inspection workers showed a higher frequency of lung cancar, especially some working with anthophyl11to in Finland.

No excess of lung cancer was found over the average population; however, when comparing with other workers, the heaviest concentration of cancer is among this group. Least exposed workers showed less incidence to lung cancer. Study showed that present disease is a result of what happened 20-30 years ago (takes disease a long time to develop), There is very ` " little evidence of disease in people during last 10-15 years. In 1959 cases of Mesothelioma {disease affecting the plural lining of the chest covering the lung) were discovered in South Africa, where crocidolite is mined. Usually a very rare disease, 50 or so cases were discovered. The strange thing was that most of the mining was done 400 miles away in the Transvaal area where no cases were reported. Few cases of the disease have been discovered in amositc mining:areas. Upon investigations in other areas, 3ome cases of Mesothelioma were found in London where Blue Asbestos has been used. There has been no definite evidence that asbestos was truly the cause, however. Bronchial cancer, related to anthrophyilite, showed no Mesothelioma. In Canada, a relation was discovered with men working in insulation industry to the disease, but none at mill or mining area. In Italy, Mesothelioma wa3 discovered in shipyard workers but not at mines. All these are dose related and must be related to something else. Dr. Newhouse investigated all records of workers at "Cape". He discovered that the highest exposure gave greatest chance of cancer (bronchial or Mesothelioma) . Light axpoauro shov/od little evidence of cancer. Cigarette smokers are more prone to develop disease. 5. Cumulative aspects -- hard to resuspend bound fiber; fiber bound does not subdivide; higher density. Talc does everything that asbestos does and more talc is used in the U.S. than asbestos fiber. The meeting wa3 then turned over to M. Fenner. Pol lowing are ray notes on Mr. Fenner's presentation with a question from Dr. Stunz.1 1. In our environmental health control efforts, good equipment is necessary but more important is monitoring the system. PRODUCED JM - 83 4 Motes on E. M Fenner's Presentation (Continued) 2. Dust can be controlled: a. Change process to one that does not produced dust or one that will have adequate dust control. , b. Monitor the system. 3. Dr. stunz of Harrison questioned, `"-'hat is count on deflashing?" Our answer would be: a. Take membrane sample for fiber b. Take station sample for particulate ' c. Calculate T.L.V, Following Mr. Fenner's presentation, De3 Smyth presented our story on bulk handling. This could be done in either of two approaches: (1) basic bulk handling; or (2) the possibility of producing and shipping in a bag that could be used right in their mix so that no free fiber would be available to contaminate the air. A visit to their plant was then scheduled and we observed the loading station where asbestos was loaded. The suggestion wa3 made that since there is a positive pressure on the sieves, there would be a certain amount of asbestos blow-back, which there was. It wa3 suggested that possibly they could use a combination vacuum and positive pressure system which Ed Fenner discussed with John Fotrubacz. Also, during this visit, v/e observed the dcflashing station where the excess flash from the molding was removed by men using a hand grinder with an air blower on it. It was indicated to me that one of the biggest objections of the men working on this job was that the glass fiber irritated their eyes. They would like to do this deflashing automatically and are considering it since they could save a considerable amount of expense and manpower if this could be effected. The conclusions from the meeting as indicated to us by Harrison personnel were that: 1. They would reconsider their proposal to eliminate asbestos fiber. 2. They would call on us for engineering help and wa would bo very happy to give it, in the event they wanted to make any further revisions in their process. 1 .

He pointed out that: (1) Asbestos dust can cause asbestosls which in turn may cause cancer. (2) If dust control is sufficiently well applied to result in an atmosphere meeting the revi.qpri standards sat in both Britain and the U.S., then a man could work with asbestos all his working life and suffer no ill effects from the asbestos. (3) All forms of dust constitute a threat to human health. Some substances like silica or talc are as harmful or more harmful than asbestos.

After some discussion of the alternatives Mr. Rnysor summed up by saying that the new facts presented by J.M. compelled Harrison to take a new look at bulk handling and that they would re-study the whole project. After lunch J.M. personnel were taken on a short tour of the Harrison plant to observe dust conditions at the hand-feeding station and the flash-grinding station. Bagged fibre is fed through a rotary air-lock into a blower system which blows the fibre through a 4" pipe to a receiving silo. Fibre is blown from this silo through a metering arrangement to the mixer. The air-lock at the hand-feeding station was leaking. Blow-back was causing excessive dust:- If a properly designed air-lock were used the dust control provided should be adequate. Dust control at the flash-grinding looked reasonably adequate. Dr. Stunz accompanied us on the tour. As a result of discussion between Dr. Wright and Dr. Stunz a request was made that J.M. give specific help in determining dust counts at Harrison and Ed Fenner agreed to set this up. Dl'RS :st D.P.R.

VISIT TO INLAND DIVISION OF GENERAL MOTORS - AUGUST 31, 1970 Brake Lining Decomposition Products Dr, Merle Gibson, Medical Director of the Inland Division of General Motors, commented during the J-M Research Center session of the Asbestosis Course held June 15 through 18, 1970, at Mt. Sinai Hospital, that results of work at Inland did not agree with the data presented by Jerry Lynch on the decomposition of brake lining materials. He agreed to set up a meeting with Dr. George Rappaport, head of the Chemical Laboratory at Inland's Dayton laboratory, to review both Inland and J-M research on this project. After several brush-offs, I was able to arrange a meeting with Dr. Gibson and Dr. Rappaport on August 31. Also present during part of the meeting were Mr. G. W. Beck, Chief Engineer for Inland, and Mr. J, (Joe) H. Overwein, Assistant Chief Engineer* Summary Dr. Rappaport doubted the validity of the general data presented by Jerry Lynch on the breakdown of brake linings. After reviewing J-M's data and discussing peripheral information, he is convinced of the validity of our data showing less than 1 per cent chrysotile content. He suggested, as a final test, that the biological effect of the brake lining decomposition products be determined by animal tests. These may be sponsored by General Motors with Dr. Selikoff. Dr. Gibson still believes asbestos to be the main cause of lung cancer, and objects to any additional input to the atmosphere no matter how slight. I doubt if he can be convinced otherwise. Discussion ' Dr. Rappaport was quite frank in his discussion, especially when Dr. Gibson was not present. Inland has done no significant work on capturing and analyzing reaction products from brake wear. They were planning to begin a project in the near future. PRODUCED JM - 33 MEMO FOR FILE: VISIT TO INLAND LABORATORIES September 8, 1970 Page 2 Dr. Rappaport had been asked to comment on the validity of Jerry Lynch's results. He reacted unfavorably to the paper and did not accept any conclusions because the paper: 1. presented only approximate fiber concentrations; 2. gave no detailed experimental techniques; 3. did not define the technique for "quantification" of fiber content; and. 4. did not define the effectiveness of collecting all decom position products. He was also concerned about whether the decomposition products, whatever they might be, were in themselves carcinogenic. The following J-M reference material was used as a basis for discussing our work and answering Dr. Rappaport's questions. 1.

Reimschussel. The discussion included: 1. A review of test apparatus and techniques, with special reference to the millipore system of collecting samples, and its known efficiency in collecting all particulate decomposition products. 2. The techniques for quantifying fiber, including the previous point count method and the more recent radioactive tracer method. 3.

Actual detailed "chrysotile11 contents in the various samples and their relationship to the chrysotile content in the ori ginal product. We also discussed certain subjects which Dr. Rappaport indicated he was particularly interested in. These included: 1 1. "Asbestos" bodies vs ferruginous bodies. 2. Factors influencing respirabi1ity of fibers, including Timbrell's work and recent Uattelle work on retention of extremely fine particulate matter. 3. Tiie proposed programs on the effect of filler diameter, filler length, and aspect ratio, including J-M programs, Webster's work, and others. Dr. Rappaport was particularly concerned with the effect of particle size and fiber diameter of the decomposition products, and its relation to respirability. 4. Extraction of minerals from lung tissue, including low tem perature ashing, and hydroxide of Hyamine treatment. After a full morning's discussion. Dr. Rappaport indicated to Messrs. Beck, Overwein, and Dr. Gibson that he was satisfied the decomposition products, in fact, contained only very small quan tities of chrysotile. He suggested the desirability of conducting tests to show that these decomposition products were not biologi cally harmful and calculating the actual "net input" of chrysotile to the ambient air from the decomposition of brake linings based on our data and known brake lining statistics. (We have already recognized the complexity of such an undertaking in our calculations on the fiber contributed by decomposition of asphalt asbestos paving. For example, how much fiber is removed per day from the atmosphere by fall-out, rain, wind, migration, etc., as compared to the input from any source of contamination.) PRODUCED JM - 83 MEMO FOR FILE: VISIT TO INLAND LABORATORIES September 8, 1970 Page 4 General Motors, through Dr. Gibson, is seriously considering funding work at Mt. Sinai, but no specific program has apparently been defined. Inland personnel were invited to visit us at the Research Center at any time to discuss the problem and any of their suggested programs. I will send Dr. Rappaport those portions of the above-mentioned Research reports which can be released without digclosing proprietary information. Dr. Gibson is still a firm believer that asbestos is the major, positive cause for lung cancer. I think he is overpowered by the Selikoff mystic and that it is worthless to try to convince him otherwise then by direct statements from Dr. Selikoff. However, the others present at the meeting could probably be convinced that no problem exists-by a few animal experiments with calcined asbestos, calcined serpentine, and brake lining wear material.

Welshman Senior Buyer Rogers Corporation Rogers, Connecticut 06263 Dear Mr. Welshman: Your letter of May 18, 1971 to our Mr. Anthony Boisclair has been referred to me for reply. Presently, there are no standards applying specifically to airborne emissions of asbestos fiber other than those that apply to discharge of particulate matter in general. The office of Air Pollution Control in the Environmental Protection Agency of the Federal Government presently is working on emission standards for asbestos-using manufacturing plants. It is expected that these standards will be published late September 1971. It is highly probable that in order to conform to these standards, process emissions of asbestos fiber to atmosphere will require high efficiency fabric bag filter-type dust collectors for control. Relative to in-plant working conditions, the new Occupational Safety and Health Bill will require that the airborne levels of asbestos fiber bo below tho established Threshold Limit Value. Threshold Limit Values refer to airborne concentrations of substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed, day after day, without adverse effect. The present Threshold Limit Value for asbestos fiber has been established under the Walsh-Healey Public Contracts Act at 12 fibers per milliliter greater than 5 microns in length, or 2 million particles per cubic foot, dependLny upon Liu: measurement technique used. It is expected that shortly the federal Government will reduce the Threshold Limit Value to 5 fibers per milliliter and will delete any reference to particulate count. Wgbuced JU-S3 Mr. Carl L.

Warr, Buyer U. S. Steel Corp. 600 Grant Street Pittsburgh, Penna. 15230 Dear Mr. Warr: Recently you requested toxicological information concerning JohnsManville Chrysotile Asbestos Fibre. It is a pleasure to provide you with this information. Asbestos is the name given a family of mineral fibers comprised of three major types -- chrysotile, crocidolite and amosite - each of which differs from the other; physically and chemically. Studies of the relationship between asbestos and health arc complicated by this diversity. Chrysotile is a white magnesium silicate, which can be attacked by acids, has a positive electrical charge and is flexible and not easily pulverized. Crocidolite is a blue ferrous sodium silicate, is acid-resistant, has a negative electrical charge, and is less flexible than chrysotile. Amosite is a brown ferrous magnesium silicate, has a negative electrical charge and is brittle and easily pulverized. In the United States, chrysotile, amosite and crocidolite asbestos are all used. Chrysotile is by far the most common, is primarily mined in Canada and the U.S., and accounts for about 90% of the asbestos consumed in this country. ' For workers who handle asbestos fibres in mines, mills, factories, and some building and insulation trades, the industry shares with doctors, Public Health officials, and others Involved in industrial medicine, a concern about possible health effects from excessive on-the-job exposure to asbestos dust. We have Inn}' roccij'iii the risk of a p.itli cul :ir lunp, difsenfio called " A'.liei. I o.'. j .inioog umi* worker:;.

Asbestosis is one of the lung diseases called "Pneumoconiosis". PRODUCED JM - S3 Mr. Samuel G. Warr -2- June 28, 1971 Recent medical studies have indicated, that the disease "Asbestosis" and ocher pulmonary diseases claimed Co be associated with Asbestosis, are dose and time related. The occupational use of asbestos fibre, therefore, can achieve the same degree of safety as the use of any other potentially toxic material providing adequate control measures are taken. The current threshold limit value (TLV) for asbestos dust as stated in the Federal Occupational HcaLth and Safety Act, Federal Register, Saturday, Nay 29, 1971, Volume 36, No. 105, Part II, Pago -0506, is 12 fibres per milliliter of air greater than 5 microns in length -a uetcrminud by the membrane filter method at 430X Phase Contrast Magnification, or 2 million particles per cubic root of air as determined by the impmgpr method of sampling. To control asbestos dust to within the prescribed threshold limit value, we recommend that operations which present a source or dust should be equipped with mechanical ventilation exhausting into a collector; utilize wet processes where possible; maintain good housekeeping throughout the work area, including removing scrap material from floor and other hori zontal surfaces. Scrap should be disposed of in closed containers. - A program of industrial hygiene environmental monitoring is highly desirable to determine that threshold limit values are not being exceeded. If dust concentrations cannot be controlled to within the threshold limit value, U, 3. Bureau of Mines approved types of respirators for pneumoconiosis producing dusts should be worn.
