NIOSH 1979 Feb:38 pages
A preliminary survey of the monochlorobenzene (108907) (MCB) production and methyl-chloride (74873) (MeCl) use areas was conducted at the Dow Chemical Company (SIC-2869) in Midland, Michigan on May 1 and 2, 1978. A total of 93 workers work at two company production sites in Midland. The MCB concentrations in five area samples were 3.51, 0.68, 1.10, 2.75, and 1.06 parts per million (ppm). The five MeCl samples collected in the Styrofoam manufacturing area indicated that three were below the limit of detection; one sample was at 0.105 parts per billion (ppb) and the other was at 0.355ppb. The author concludes that the concentrations for both compounds were well below the OSHA standards. He recommends that continued and improved industrial hygiene practices be utilized to keep worker exposures within the standards.
