Environmental and personal air samples were analyzed for manganese (7439965), calcium-oxide (1305788), iron-oxide, and total particulates at the Interlake Steel, Inc., (SIC-332) Wilder, Kentucky, on August 30 and 31, 1978. An evaluation request came from an authorized representative of employees of the United Steelworkers of America, Local 1870, on behalf of about 100 affected workers. Manganese air concentrations were below the OSHA standard of 5.0 milligram per cubic meter (mg/CuM). Calcium-oxide concentrations ranged from 0.04 to 72.0mg/CuM, compared with the American Conference of Governmental Industrial Hygienist's (ACGIH) recommended standard of 2.0mg/CuM. Iron oxide concentrations ranged from 0.10 to 5.10mg/CuM, compared with the ACGIH recommended standard of 5.0mg/CuM. Total particulates ranged from 0.37 to 31.8mg/CuM compared with the ACGIH standard of 10.0mg/CuM. The author concludes that the bulldozer operator was exposed to excessive concentrations of calcium-oxide, and nuisance particulate, and the tractor operator was exposed to excessive concentrations of calcium-oxide, iron-oxide, and particulate. Recommendations include the possibility of storing limestone outside the melt shop, the possibility of wetting down all debris, yearly chest X-rays for workers in dusty environments, the use of personal protective equipment, and improved industrial hygiene.
