An industrial hygiene survey was conducted at Bachmeier and Company, Incorporated (SIC-5161), Kearny, New Jersey. This was a dye distribution facility which blended and repackaged imported and domestic dyes for resale. Possible worker exposure to benzidine congener dyes was the purpose of the visit. Exposures to o- dianisidine based dye, a o-tolidine based dye and a benzidine based dye were evaluated. Air samples and surface wipe samples were taken along with employee urine specimens. During the survey a blending operator poured a liquid o-dianisidine based dye for 10 minutes during which time the sampling equipment indicated no detectable exposure to the worker. During a blending of a dry benzidine based dye operation the blending operator had the highest exposure of 1.18mg/m3. The forklift operator registered an exposure of No detectable levels of free benzidine (92875) or benzidine congener metabolites were found in the urine of blending and forklift operators. Two urine samples from a shipping employee revealed 3.4 and 3.8 micrograms/liter of free benzidine in the urine. No free o- dianisidine (119904) or o-tolidine (119937) metabolites were detected in any urine samples. Recommendations were made to reduce dye exposures at this work site through the implementation of engineering controls and employee training.
