Abstract |
Worker exposures to asbestos (1332214) were surveyed in May and June, 1970, at Johns-Manville Corporation (SIC-3292) in Stockton, California. Asbestos concentrations in the warehousing and mixing, pipe forming, curing, pipe finishing, coupling finishing, epoxy, packaging, and miscellaneous areas of the facility were 0.4 to 1.3, 0.0 to 0.9, 0.2 to 0.9, 0.1 to 1.7, 0.0 to 1.6, 0.3, 0.0 to 0.9, and 0.2 to 1.1 fibers greater than 5 microns per cubic centimeter (f/cc). All samples were below the 1970 threshold limit value for asbestos of 5.0 f/cc. |
