Smith Research and Engineering Confer December 13, 1966 received Asbestos-'envi ronmenta f Problems Status Report October-November 1966 \. Packings and friction Materials Division APR 1919/6 LEGAL. SEHVtC Study of wear products from friction materials (J. Dec) During the period October I through November 30, (966 the wear dust collected from the special dynamometer enclosure was analyzed in detail. The results were unexpected in that asbestos fiber could be detected only by the electron microscope which indicated a maximum of 1.4 per cent by weight fibrous debris. This is in contrast to about 70 per cent by weight chrysotile fiber in the original friction material. David Sinclair has accounted for the difference in fiber content by suggest ing that high surface temperatures and severe abrasion convert the asbestos fiber into an amorphous mineral. He further demonstrates mathematically that the very high temperatures (2000F) required to break down fiber to this extent could be generated at the contact surface of a friction material even during ''mild" braking in which the apparent temperature does not exceed 20Cf. This derives from the fact that the true area of contact in the friction couple is about one per cent of the apparent area. From this work it would appear that the fear of iarge quantities of asbestos fiber being Introduced into The atmosphere as part of the wear dust of friction materials is unfounded. However, the tests to determine the bio logical effects of such dust, regardless of its fiber content, are not complete, end we are therefore not in a position to draw final conclusions. 2. Pipe QWvsion . A. An Inexpensive inner coating for TRANSITE pipe O* H. Swensen) A development program (Project P-22) is under way to develop an ''improved Soft Water Coating for PotabJe Water Pipe." The present coating, based on asphalt, has become more and more unacceptable due to taste and odor problems. Efforts are being directed toward * a clear coating which will not affect water quality. Polyterpene- type coatings have looked premising although their UV resistance now appears to be less than satisfactory. A coating developed within this program will have to be inexpensive and may fill the needs for a general TRANSITE pipe coating. It Is hoped that the improved soft water coating can be commercealized in the first quarter of 1967. * B, Effect of water flow through TRANS ITE pipe ' V' X-4i'v-* * '< Jv* A layout of a system for studying the effects of flow and water composition on TRANSITS pipe has been prepared, and an assignment has been placed on the Engineering Department. Probably this system will not be operational until the second quarter of 1967. /A. C. Smith -2- Oecember 13, 1966 3. Fiber Glass Insulations Hgffi ^'Iryr "'>J j Residue from flow of air through fiber glass ducts, eW^^G, J. Hennes) 7 initial tests run by the Kettering Institute with Owens-Corning Fibergias duct indicated no measurable release of fiber Into the air stream. Much more extensive tests are under way now In the 0-C laboratories under the supervision of the Kettering Institute. Johns-Manv\ Me duct liners and duct board are part of these tests, which will include a variety of air flow conditions. Complete data will not be available until about March I 4. Pui!dInq Products Division 967 A. Degradation products of asbestos feit built-up roofs (J. Q. Trice) The Instrument Development Company of Reston, Virginia, a division < of Resources Research, Inc., is preparing a prel iminary engineering drawing and specifications for equipment which they propose for the <+ actual weathering and collection of materials. Briefly the environ- w mental chamber will consist of four components: (a) the mechanical chamber, (b) the radiation system, (c) the air handling system, and (d> the liquid handling system, Detailed information will be avail able from the Instrument Development Company by .December 15. We now believe that the actual samples for weatherir.es will have to be prepared outside the environmental chamber because of the high concentration of material thrown from the hot asphalt and from working with the roofing felts. After the samples have been prepared, one will be exposed in the environmental chamber and a second exposed on the roof of the Research laboratory so that at least visual observ ations can be made comparing the performance of the two samples. Materials produced or released during the weathering process will fall Into three categories: (a) particulate - which wiM be collected on membrane filters (b) water-soluble - which will be picked up by the wash water which must also be put through a membrane filter in order to collect solids which are removed by washing (c> vaporized materials - which will be collected at the low temperature traps in the air circulating system. B. Degradation products of asbestos-cement materials A program for sampling and testing materials has been drawn up. The TesT program will Include an examination of field-exposed material which has been in service for many years as well as laboratory exposure of products. In the case of field-exposed products, since shingles are partially exposed and partially covered In use, it is possible for us to obtain good reference samples and analyze the changes that have occurred to the exposed surface. ' ' A preliminary examinarion of some vertically exposed norma I-cured products after long exposure shows the following. % j Lr. -3- December 13, 1966 t / Source of Samples Products Exposure Period ThIcknoss decrease durinc exposure, inche JM office building, Manvi He, New Jersey Dry process shingles 1918-1964 0.003 to 0.020 /j*g JM plant, Nashua, New Hampshire Ory process Shingles pre-i 926*-1 966 0.CQI * JM p\ant, ' Nashua, New Hampshire Flat TRANSITS 1921-1966 0.006 JM plant, Nashua, New Hampshire Corrugated TRANS\TE l924-\966 0.012 The small amount of weathering exhibited by these products points up the need for very precise measurements In this test program. Flooring Division Wear products from flooring materials (J. Q. Trice) Experimental work has not yet been started in this program. 6. General Company Research - Organic material in asbestos fibers (f. L. Pundsack) Cape S Blue, packed in paper bags and in jute bags, was obtained from the Manville Pipe Riant, and the organic content extracted. The blue fiber packed in jute bags contained up to sixty (60) times as much organic mate rial as did the fiber packed in paper bags. Jeffrey chrysotile p*c**o in paper bags and in jute bags is being analyzed in the same way, and data will be avallable soon. We are working with a company named Ana I tech to develop methods of Identify ing all the trace organic substances present'In asbestos. It may be of Interest to note that in 1965 In the United States approxim ately five (5) times as much benz(aJpyrene was released in the form of cigarette smoke as was contained In all the asbestos used in this country for all purposes In the same year. Incidentally, more than one-half the benz<e)pyrene associated with asbestos was contained In the approximately 40,000 tons of imported blue fiber. F* U Pundsack ee cc: F. J, Solon - GHO K. W.

The Academy meeting will be held in the San Francisco Hilton Hotel on February 8 to 10. I am enclosing a program which covers the time and gives the location of the sessions. I do not have a copy of my paper yet, as Z have not prepared the final version; but I will see that you have one in advance of the meeting. What I propose to do is to revim briefly the present evidence of the major health effects of asbestos and to point out the many gaps in our knowledge and the hazards of extrapolation. X will emphasize, however, my own feeling that it is not improper to speculate as to the signi ficance of certain findings which ve are in the process of studying. I will get this to you in more specific terms for your critique. The periodic health examination program to which you refer is that run by Dr. Morris Collen of the Permanente Medical Group. I am enclosing a reprint C describing the setup. I talked to Dr. Collen this morning and understand that arrangements have been made for visitors on Thursday morning, February 9. I as looking forward to seeing you; and If you will call me when you get into town, ve can arrange to get together sometime on February 7. I hope you will be able to visit us in Berkeley.

The authori zation was given verbally on a number of occasions, and especially after a letter of October 14, 1966, which was written by Dr. Ralph Smith, my deputy, while I was away in Europe and Tokyo. A copy of that letter is enclosed for your immediate reference. Subsequently, and in view of that letter, Dr. Ken Smith again verbally authorized us to proceed. The enclosed letter outlines the concept of the study. Currently, we have completed cutting a large number of thick sections, which have been processed through various staining procedures and which have been studied microscopically. Smears of the lung have also been made and studied in order to detect the possible presence of fibers and/or bodies, either asbestotic or otherwise. Also, we have prepared a number of samples of airborne particulates collected by various means from the exposure rooms and from the outdoor air at street level. The preparations have been processed at dif ferent temperature levels in order to remove combustible organic material and to leave a residual of temperature- ^ resistant particulates and fibers. These samples have been subjected to conventional light microscopy, phase microsce^ '-fS and electron microscopy. Currently, enlarged photographs 3*^ are being made for purposes of detailed visualization and & counting. In a few days, all observations will be compiled for & ^ Mr, Hugh Jackson - page 2 - February 8, 196? a comprehensive report to you. Incidentally, the studies were undertaken in consequence of views expressed at the Asbestos Conference in Antigua, last year. In accordance with the enclosed letter of October 1 4, 1966, a figure of $7, 000, 00, was given as the estimated budget. Irrespective of our expanded efforts, I will abide by that figure. Up to the present time, however, we have been financially supporting the study with limited funds, but I have verbally agreed to give overtime reimbursement to certain staff members for their efforts in behalf of the study. I did this., believing that such disbursements were proper on the basis that the total sum would be forwarded to me as a fee for consultation. In that regard, and in view of the circumstances, Hugh, I defer to the decision by you and your company. Above all, I do wish to avoid any embarrass ment to you and your company. In any event, we will proceed toward completion of the study as originally conceived and authorized. With all best wishes. Sincerely yours.

Confirming our phone convert ation 1 should like to describe the research effort to be carried out by our Depart* meat relating to the detection of asbestos bodies in animals not exposed to asbestos. Specifically over the past five years approximately 1.000 animals have been sacrificed and tissue specimens preserved for microscopic study. Approximately half of these animals have breathed outside air somewhat enriched in automotive exhaust products, while the other half have never breathed air containing particulate matter. It appears that it will be necessary to cut thicker sections then have already been cut and accordingly a representative number of animals tissue will be so treated. These thick sections will then be scrutinised to determine whether or not asbestos bodies are present. As a corroiary study particulate matter which was removed from the air by filtration will be examined to determine whether or not asbestos fibers can be identified. We recognise, of course, certain experimental difficulties which may render It nearly impossible to be certain of the presence or absence of fibers and will welcome any technical guidance which your laboratories may offer. In this connection we are sending a sample of atmospheric dust and will be interested in your findings. Although it is difficult to estimate the expenses, it is ^ the opinion of Dr. Vorwald and myself that approximately $7. will be required. In the event that the findings are eufficinatiy interesting, and we mutually agree that even more work is required* It is our understanding that you would favorably consider additional Dr* K. W. Smith 2- - October 14, 1966 /urtdf upon request, in order that the work can be done more expeditiously we would suggest that funds be made payable to f'Asbestos Study Project" Arthur J. Vorwald, Ph. D. , M. D., Agent. A checking account will be opened with this designating and will of course be subject to audit at any time. We look forward to carrying out this interesting study and hope that the results are informative* Perhaps when you see Arthur in Tokyo next week you may covnp up with other ideas which will further enhance the scope of the study. Have a good trip* Very truly yours, RGS;glg d CL \ Ralph G.

We visited several countries, many clinics, and duly repartee). At the request of the QAMA. Dr. Cartier and I went to Copenhagen, Denmark, in 1066, to attend the international meeting of the College of Chest Physicians. At this time , in the suite of Karl LindclL in the Hotel Hoyale, Dr. Cartier and I were asked to attend Die international meeting on occupational health to be held in Vienna in September, 1966, and the international meeting on cancer in Tokyo in October, I DOG. The travel schedule, seemed to he too arduous, so it was recommended that Dr. Cnrticr should go to Vienna, and that I should repine sent the QAMA at the Tokyo and associated meetings. As requested, and accompanied by my wife, Marjorie, I went to Tokyo for. the international con ference and attended associated meetings on pulmonary physiology and pathology at other centers. I obtained travel expense money from Johns - ManviUe and submitted my expense account to Karl Linde 11 and the QAMA in December, i960. This was thoroughly discussed in the presence of Dr. Cartier, Mr. Ivan Sabourin, Dr. John Beattie, at our meeting when I reported December 17, 1966, at the Hotel in New York. aboul the authority to use Hie fluids for travel to the Orient. Now, after many months of reflection, I feel lhal T must re-submit my statement for expenses this, but first. I would appreciate your feeling on Hie method of doing so--you Sincere ly, Ken W.
