He stated that the company is committed to complete elimination of asbestos from its product "Monokote". Thus the Board's con sideration should be considered only as an interim measure pending elimination of asbestos from fire proofing. He said that in San Francisco conditions are far better controlled than in New York. Tabershaw Cooper was engaged to gather needed data. Mr. Chaney summarized by citing steps his company is taking to achieve safety in application of fire proofing material. Dr. Dritz cited measurements at Wells Fargo Building during spraying operations (this report is contained in asbestos file furnished Board previously). Measurements at other sites were noted, and are available from the State Division of Industrial Safety. Dr. Dritz cited 2.0 million per cubic foot as threshold limit and peak acceptable as 5.0 million per cubic foot. Dr,,. Cooper pointed out difficulty of distinction between particle counts and asbestos fiber counts. Smallest particles are probably asbestos. Mr. Fowler submitted July 17, 1970 report of Tabershaw Cooper Associates, "Preliminary Examination of Air Moving Systems Lined with Cementitious Fireproofing Materials." Mr. Harry S. Gropp, United States Mineral Products Company, stated that measurements are being made at plenums where their products have been used. Mr. Whittaker, Fireproofing and Acoustical Contractor, stated that this was his first meeting on subject and he objected to stating of any test criteria for con trol without having been consulted. Board of Examiners Special Meeting - Asbestos Minutes of Meeting July 21, 1970 Page Four Hazards (TAPE 100) , (TAPE 130) ' Mr. Oliphant pointed out that the Board has made no determination of criteria, only discussion has occurred thus far. Mr. Goldberg reviewed previous Board considerations of subject to verify that no decisions made. Mr. Oliphant emphasized that this was first time Board was considering the subject with possible expectation that action may occur. Mr. John Fisher stated that Bechtel has engaged Abbot Hanks to gather data in plenum air. Mr. Dalton, Abbot Hanks, stated that work has been begun in the gathering of fiber counts3 no reports available as yet. He emphasized that he had not been engaged by any fireproofing industry segment but was objectively gathering data at this time. Messrs. Whittaker, Fisher and Goldberg discussed possible numbers of buildings with supply air plenums; conclusion that there were very few such systems. Mr. Douglas Fowler stated measurements taken at various points in or near plenums are low - no significant differences between the two types of fireproofing material. Oldest system where measure ments taken was constructed In 1962. He cited difficulties in correlating measurements where different sampling techniques and different equipment is used. Use of electron microscope in measurement is new. Mr. Degenkolb pointed out inference that asbestos fibers were only a small portion of total particle count. Dr. Dritz emphasized that the asbestos fibers were the ones causing this particular hazard. Mr. Fisher noted problem of aluminum pitting due to use of cementitious products in vicinity. Board of Examiners Special Meeting - Asbestos Minutes of Meeting July 21, 1970 ~ Page Five Hazards (TAPE 210) Mr* Yosick, United States Gypsum Company, cited discontinuance of use of Firecoc'e Plaster in San Francisco on January 1, 1970. Mr, Oliphant closed the meeting at 9:15 PM. The Board recommended that the Superintendent prepare an outline of preliminary construction regulations to limit the "public nuisance" as well as the effect on construction workers. That preliminary set of regulations are to be forwarded to all persons at the hearing as well as all others on the asbestos mailing list. A hearing will be held on those preliminary regulations in September at a date to be set at the next regular meeting of the Board on August 10, 1970. Mo discussion of the regulations other than setting of the date of the next hearing will take place at the August 10 meeting and all persons will be immediately notified of the date of the September meeting. f'J ( Alfred Goldberg, Secretary Board of Examiners Attachment - Attendance List Tabershaw-Cooper Associates Report
