ASBESTOS WORK PRACTICES PLANT 512 & 511 CONSTRUCTION 511 Field fabrication has 511 Fabrication Shop has 15 employees 9 employees 24 Total employees work asbestos Cdntral Insulation has 13 employees - working asbestos Maintenance areas have 24 employees - working asbestos 61 Total - In-plant asbestos work force Does not Include supervisory personnel. Prior to January 1, 1973 -- application of asbestos containing materials is involved mostly in work with tape, and block material. Block materials may be,pre-formed or formed on-site. Old insulation is removed by all field insulators with che intent of salvage and replacement. Reported frequency -/argil's from two to 50 per cent among various groups. Clean-up of work area is generally unacceptat(gSl inall"areas. Left over waste is saved if considered salvagat^i\ In no case is vacuum sweeping practiced. Wet spray before cleanup is not practiced among any group. 31 per cent claim rough clean by sweeping then hose down for final cleanup. Remaining 69# dry sweep only. ... Plastic bags are in use to some degree by 18$ of insulators. Waste material from other 82# of work is placed in dumpsters, or dump truck to be transported to land fill. Dump trucks are covered' during transport. Dumpsters may or may not be covered. 5 ^ Engineering methods of protection such as enclosure, isolation, or wind shielding is npn-existant.

However, meaps of dust removal for disposal. is totally inadequated. This is obviously the greatest single exposure source within the plant. . Portable power equipment such as shaping saws is not in use at any location. - In three of eight areas where insulation work is performed, ere are claims of vacuum sweepers being available for use. In no case is a vacuum facility provided and readily available for use. Personnel employed in cleanup efforts varies with work locations. Some maintenance areas claim 75$ cleanup by the insulators, whereas, other areas have 100$ cleanup by laborers. Some individual insulators suspect their greatest chance for exposure to be during unpacking pre-formed insulation. There is no way to escape the liberated dust. This is substantiated by the 40 fiber count measured during the packing job. . Other workers that have undetermined amounts of asbestos exposure are, dumpster drivers, truck drivers, insulator foremen, landfill heavy equipment operator, and craftsmenC working in areas adjacent to insulating jobs. Asbestos containing materials are in use in the laboratory in the form of: filter aids (100% fibers), column wrapping with tape, asbestos gloves, glass blower workbench top and as heat shields. Asbestos bLankets are used as shielding material in othbr areas such as Area V shop and furnace areas. A type filter aid which contains asbestos is still in use at #1 powerhouse and possibly at water treating plants.
