In response to a request from Local 169, United Steel Workers of America, an evaluation was made of vapors in the Cold Rolling Mill of Empire-Detroit Steel Division in Mansfield, Ohio. Another concern was the possible accumulation of acid vapors accumulating in the crane areas from an adjacent pickling operation. Bulk samples of coolants were taken as obtained from the supplier and as used as emulsions at the facility, for analysis. A large number of hydrocarbons were released on heating the coolants. Sampling of area air space revealed kerosene, at nondetectable to 6.1mg/m3 levels, and oil mists from nondetectable to 0.3mg/m3. Acrolein, a potential degradation product, was not detected in any sample, while formaldehyde ranged in concentration from 0.004 to 0.06mg/m3. No sulfuric acid was detected and hydrochloric acid was detected in only one sample at 0.7mg/m3. Personal breathing-space samples contained kerosene ranging from not detectable to 6.7mg/m3. No evidence to support crane operator exposure to acid mists was found. The author concludes that no chemical exposure representing a health hazard to the workers has been identified.
