Description:The International Chemical Workers Union requested an evaluation of occupational exposures to suspect bladder carcinogens at Hilton Davis Chemical Company (SIC-2865), Cincinnati, Ohio. Of about 30 workers in the Pigments Department, four were involved in handling 3,3'-dichlorobenzidine (91941) (DCB). Personal breathing zone air samples, area air samples, forearm gauze patch samples, and wipe samples from various surfaces were gathered. All four personal breathing zone air samples and three of four area air samples contained low but detectable quantities of DCB. Seven of eight skin gauze samples contained 0.2 to 3.7 micrograms/25 square centimeters and 19 of 26 wipe samples showed 0.4 to 2800 micrograms/100 square centimeters. Low, but measurable, concentrations of DCB were present in the urine of workers who performed the DCB charging operation. The authors conclude that a potential health hazard existed due to exposure to DCB. There were deficiencies in the personal protective equipment and in the decontamination procedure. The authors recommend that appropriate ventilation should be used in the charge room. Effectiveness of decontamination with hypochlorite solution should be examined. Workers should be instructed concerning proper decontamination and should be provided with sufficient time for decontamination. Periodic sampling for urinary DCB should be instituted.
