Abstract
A survey was conducted to assess methods used to control occupational exposure to benzidine (92875) and 3,3'- dichlorobenzidine (91941) (DCB) at the Allied Chemicals Corporation (SIC-2869) facility at Buffalo, New York, in October 1972. The facility relied on engineering controls and work practices to reduce employee exposure. The reactor vessels and lines were isolated and enclosed. The equipment was ventilated and exhausted through water scrubbers on the roof. The effluents from the scrubbers and other points were treated to destroy all traces of benzidine before being released to factory sewers. Routine decontamination procedures were also used to reduce employee exposure. Air and wipe samples were taken and analyzed as a part of a monitoring program to determine if abnormal exposures were occurring. Workers were required to wear protective clothing. The production process for DCB was enclosed until the final packaging in drums where it was handled in the open as a moist powder. The authors recommend that engineering controls be established to prevent operator contact with the moist DCB and that ventilation of the drumming area be improved.
