摘要

On June 10 and August 16, 1979, the National Institute for Occupational Safety and Health (NIOSH) conducted an environmental evaluation at L.R.I. Industries, a maker of ceramic tubling media, in Chelsea, Michigan, to evaluate possible hazards from noise, from dusts containing free silica, and from asbestos. Environmental measurements were made for airborne particulates containing free silica. Bulk samples of batch ingredients were obtained for asbestos and other analyses. One noise dosimeter reading plus five noise level readings at ear level using the dBA slow response scale were taken. Informal interviews were conducted with employees regarding work histories and work conditions. The chief complaint from most employees were the poor condition and location of eating areas.
