Worker exposures to fibrous glass (14808607), silica (7631869) dust, and fibrous talc (14807966) were surveyed on April 10 to 14, 1972, at Owens Corning Fiberglass (SIC-2221) in Newark, Ohio. The company employed about 2400 workers, 2000 of which were blue collar workers. On site medical facilities were available and were staffed by registered nurses. Preemployment medical examinations and periodic chest X-rays were provided. Safety glasses and hearing protection devices were available to the workers. In the wool area, concentrations of fibrous glass ranged from 0.00 to 0.83 fibers less than than 10 microns per milliliter, and concentrations of dust were 1.0 to 35.7 milligrams per cubic meter (mg/CuM), with silica contents of 0.13 to 6.1mg/CuM. Dust concentrations in the glass batch house were 1.3 to 6.5mg/CuM with silica contents of 0.11 to house were 4.5 to 32.0 fibers greater than 5 microns per milliliter, and 1.8 to 7.0mg/CuM with silica contents of 0.1 to 1.1mg/CuM, respectively. Exposure standards for silica dust content are standards for talc and fibrous glass were not provided. The authors conclude that workers in all three areas of the facility are exposed to excessive silica dust concentrations, and workers in the paint house area also are exposed to excessive fibrous talc concentrations. They recommend improved ventilation, use of respirators, and strict enforcement of eye and hearing protection programs.
