Paa* -3 December 9, 19o6 C. A. D*Alonzo, M.D. Asbestos To supplement that 1attar and to elaborate further on each question In your questionnaire, I submit the following: B. Occasionally aechanics from other craft* are 'used aa part-tins Initiators. These men can vary from day to day but practically all mechanic* get some exposure to aibeatoe during field wor.:. There is constant handling, cutting. Installation, removal ar.d replacement going on to varying degrees by many employees wh ere not classified as pipecoverers. C. It is difficult to determine, with any degree of accuracy, the most prevalent type asbestos-containing insulation saterial used. Orest quantities of asbestos-containing materials are used on Chambers Wonts. These materials come in tny number of sizes, shapes, rolls, drums, mixtures with other nonasbestos-containing materials, vet, dry, powdered, paper, aiding, floor covering, cloth, etc. Thus to assess quantity la difficult when one tries to compare. The type used for the insulation, its thichness, handling, locale, and means of application are all factors in the assessing. More than one supplier la used to obtain our materials and the type material used varies with the Chambers Worhs Construction group and the Chambers Vorum Engineering M&C group. Based on quantities purchased for use by the latter group during 1965 as compared with 1966, there la a distinct over-all decrease in use in 1966 of asbestos-containing materials. S. With a total of 1,420 wag* roll men in Class II, HI or 17, 100 are so classified for pulmonary reasons. Of this 100, two are pipecoverers. (See letter of 8/19/66.) Since the year 1950 through 1966 to date, we list 1,319 employees as deceased. Of these, 130 died from pulmonary reasons and of this 130, 53 were from carcinoma of the lung. Of the total deaths, only 5 were ever pipecoverers. One of these insulators died listed as "cor 4 were nonpulmonary causes. W.^Tleeld, Jr., x.D.
