The follow ing Tooints were agreed upon and a tentative write-up will be forwarded to the Board of Governors for review, 1. Differentiation of asbestosis and silicosis. . 2. Bibliography on asbestosis 3. Medical control -- preplacement and periodic examination ii. Engineering control. fii Environmental survey and evaluation, A statistical evaluation of the data resulting from the industrial hygiene sur vey program was discussed. Xn summary, although the 210X magnification reveals more fibres than the 10CK magnification - the ratio is constant to a significant degree. Therefore, the present standard technique (10CK magnification) will give valid indication of the relativo fiber content of survey samples i The _ ' charts and interpretation are attached. D. R. Holmes reported that Dr. Theodos has been working on two areas of research: the. relationship of the heart to asbestosis and the effects of Intermittent Positive Pressure ng_on asbestosis. It was the consensus of the com- rcittee (later approved by the 3oard of Governors) that Dr. Theodos be invited to present his papers to the doctors at our next meeting. A review of techniques and problems in the use of fibre conditioners was made. Written reports of each members experience have been forwarded to Dr. Shaw for use in his investigation of fibre conditioning techniques. Hew Jersey State Department of Labor has not accepted the recommendation of its Standards and Codes Committee in regards to asbestos exposures. There is no reference to a maximum allowable concentration- for asbestos in the revised . code; This action resulted primarily because the American Conference bf Governmental Industrial Hygienist continues to ppbeify limits for asbestos in terms of dust instead of fibre. It points up the need for further information and valid records pertaining to the incidence and exposures involved in asbestosis. I. It was '.urged that autopsies be obtained in as many instances as possible. The procedure for the study of such by Saranac Laboratory will be reviewed at the next meeting with the doctors. Several members made inquiry concerning air hygiene sampling services - since state agencies are not available for frequent checks.
