Abstract
Personal and area environmental samples were analyzed for the presence of carbon-black (1333864), lead (7439921), and antimony (7440360) and total particulates in the compounding area and mill room at the St. Clair Rubber Company, (SIC-3069) in Marysville, Michigan, from May 14 to 16, and November 19 and 20 1979. The evaluation was requested by a vice president of the company. The factory employed about 160 workers. Ten to 16 workers were assigned to the compounding area where raw materials were batched, mixed, milled, and calendered. Total dust particulates ranged from 0.03 to 6.9 milligrams per cubic meter (mg/CuM), one lead sample was 9.7 micrograms per cubic meter as an 8-hour time weighted average (TWA), antimony concentrations ranged from 0.01 to 0.15mg/CuM and carbon- black concentrations ranged from 0.11 to 2.59mg/CuM. Dust particulates, lead, antimony and carbon-black OSHA criteria standards were 10mg/CuM, 30 micrograms/CuM meter for an 8 hour (TWA), 0.5mg/CuM and 3.5mg/CuM for an 8 hour TWA, respectively. The author concludes that there were no hazardous exposures to dust containing carbon-black, lead or antimony under existing conditions. He recommends that work practices be closely monitored to minimize exposure to lead and antimony and that their suggestions for further reducing exposures be implemented.
