Abstract
Worker exposures to trichlorofluoromethane (75694) (G11), dichlorofluoromethane (75434) (G12) and carbon-tetrachloride (56235) (CCl4) were surveyed at Allied Chemical (SIC-2869), Specialty Chemical Division, in Danville, Illinois, on March 30 and 31, 1976, and August 23 and 24, 1977. The company employed 44 to 74 workers, and provided medical and industrial hygiene services. In the product manufacturing area, personal exposures to G11, G12 and CCl4 ranged from 3.5 to 39.3, 0.2 to 43.1, and 0.17 to 1.9 parts per million (ppm), respectively. In the product packaging areas, G11 and G12 concentrations ranged from 6.2 to 764.0 and 0.5 to 73.0ppm, respectively; no CCl4 was detected. Current exposure standards are 5600 milligrams per cubic meter (mg/CuM) for G11, 4950mg/CuM for G12, and 720mg/CuM for CCl4. The author recommends continued use of existing engineering controls, better use of enclosures in the packaging area, and use of dry ice to chill sample cylinders.
