Abstract
An on site visit was made to the S. B. Foot Tanning Company (SIC- 3111), Red Wing, Minnesota to conduct an in depth industrial hygiene survey of a chrome tannery to document worker exposure to tanning chemicals. The company had the daily capacity to process 6800 hides per day, and produces fully tanned and finished leather cow hides. Of the 394 full time workers, 293 are involved in production. N- Nitroso compounds were not detected in the walk through study and the company does not use dimethylamine-sulfate in the dehairing process, thus reducing the probability of nitrosamine formation. Airborne nitrosating agents were found at all the sampling sites, but all the findings were in line with accepted limitations. However, the finding of free benzidine (92875) in the two bulk dyes indicates a need to inventory the dye room and remove from stock all dyes that contain free benzidine. Local ventilation should also be provided to the Finish Mixer to lower the environmental levels.
