F OUNDATION F ACTS NEW MEMBERS: The Foundation is pleased to add the names of The American Welding b Manufacturing Company, Standard Oil Company (Indiana), and Westinghouse Air Brake Divi sion, Westinghou3e Air Brake Company to membership. MEETINGS: A Chemical-Toxicological Committee sponsored Threshold Limit Values Workshop on February 2, attended by 40 registrants, was chaired by Dr. Emil A. Pfitzer of the University of Cincinnati's Kettering Laboratory. Dr. H. E. Stokinger (Chairman of the American Conference of Governmental Industrial Hygienists Threshold Limit Committee) was principal speaker and presented documentation in support of 1967 intended changes. He advised of a proposal that in the future the old values be retained tinder "Recommended Values" and intended changes appear only as a "Statement of Intent." If adopted, this should help fore stall transposition of new tentative values to serve in the place of values formerly recommended, especially where these are used in legal codes. There appeared to be unanimous endorsement of this proposal by those present and Dr. Stokinger expects that his committee may be inclined to act favorably upon it. Dr. John A. Zapp, Director of duPont's Haskell Laboratory, is a member of the American Industrial Hygiene Association-American Conference of Governmental Industrial Hygienists Committee on Threshold Limits, which has proposed a revision to the preface to the Threshold Limit Values. Dr. Zapp discussed the rationale for the proposed modi fication, indicating that it would better fit the needs of users, and be less likely to be mis construed if introduced into legal codes. Mr. T. F. Hatch, Professor Emeritus of the University of Pittsburgh, Graduate School of Public Health, said the most precious possession of the indus trial hygienist is the knowledge that individuals may be exposed to contamination below certain levels without adverse health effects. Professor Hatch argued against inclusion of limits based on considerations other than health in the Threshold Limit list. There was general agreement that separate listing of substances for purposes of health versus housekeeping is essential to proper understanding and use of Threshold Limit Values. At a meeting of the Board of Governors of Asbestos Textile Institute.at Cherry Hill, N. J., February 9, Dr. deTreville reported progress on the Foundation's research on fibrous dusts, including asbestos. (Medical Series Bulletin No. 11, distributed in December 1966, and entitled "Asbestos Bioeffects Research for Industry" describes these studies.) ,____________________ _____________________________ , | 32nd ANNUAL MEETING--OCTOBER 10-11, 1967 ~| 03122397
