Worker exposures to monochlorobenzene (108907) (MCB), benzene (71432), and dichlorobenzene (25321226) were determined at the Montrose Chemical Corporation (SIC-2869) in Henderson, Nevada, on January 24 to 25, 1979. Approximately 68 of the employees at the facility handle MCB on an intermittent basis. The company maintained a safety program and inhouse industrial hygiene activities were augmented by a regional industrial hygienist. Medical services were furnished by a local hospital and company personnel trained in first aid. MCB concentrations ranged from 0.1 to 14.2 parts per million (ppm), compared with the OSHA standard of 75ppm. Benzene concentrations ranged from 0.1 to 5.5ppm compared with the OSHA standard of 10ppm and dichlorobenzene concentrations ranged from 0.1 to 0.8ppm.
