E. B. PARKER ROCKDALE WORKS TO DR. W. T. WASHAM ROCKDALE WORKS CONFIDENTIAL 1987 July 02 RE: ASBESTOS EXPOSURE On June 29, 1987, you asked me for any information in our files which might indicate the degree to which Edwin Joseph Gaas and Melmuth Odell Farr have been exposed to asbestos during their Alcoa working career. Mr. Farr spend the first two months of his employment in the Utility Department. He then moved into Potlining and worked there for nearly 31 years until June of 1984 when he transferred to Yard Service. During his first 20 years in Potlining, Mr. Farr could have been exposed to asbestos since that was the insulating material used in pots. However, we have no data to confirm or deny such exposure. Mr. Gaas has spent most of 32 years working in the Potrooms. He did, however, spend three (3) weeks in Potlining in September, 1962, where he could have been exposed to asbestos during installation of pot insu lation, and about five (5) weeks in the Carbon Plant in January and February of 1963, where one of his jobs could have been patching cracks in flue walls with a mixture of asbestos shorts and molasses. Again, we have no test data to confirm or deny asbestos exposure. From November 26, 1963 until October 31, 1983, Mr. Gaas worked as a Tapper Carbon Changer in the Potrooms. One of the crew's jobs was replacing siphon gaskets which, until about 1973 or 1974, were made of pre-cut asbestos millboard. In my opinion, any asbestos exposure which might have occurred while handling these gaskets, would have been very low. However, there is no Environmental Superintendent EBP/jb:707 Attachment cc: G.
