Abstract In order to determine whether additional industrial hygiene surveys to quantify worker exposure to monochlorobenzene (108907) (MCB) were justifiable, a study was undertaken at a DDT manufacturing facility in Torrance, California, where MCB was used in the manufacture of DDT. Exposure levels which were recorded were below the threshold limit value. DDT was produced in a fairly open structure with both natural and forced ventilation to keep worker exposures to a low level. The potential for MCB exposure was greatest when a quality control sample was taken and when DDT scrap was added to the rework area. During a simulation of the rework operation, a short duration concentration of 6.58 parts per million was obtained. The potential did exist for short term, higher levels of exposure. The potential for exposure to DDT (50293) far outweighted the potential for exposure to MCB. The authors conclude that additional studies should be made at the facility, emphasizing DDT exposures.
