NIOSH 1987 Nov:29 pages
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 (SIC-3312) 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 (8008206), at nondetectable to 6.1mg/m3 levels, and oil mists from nondetectable to 0.3mg/m3. Acrolein (107028), a potential degradation product, was not detected in any sample, while formaldehyde (50000) ranged in concentration from 0.004 to 0.06mg/m3. No sulfuric-acid (7664939) was detected and hydrochloric-acid (7647010) 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. The author recommends that a further analysis be undertaken at a time when the production schedules call for increased activity at the facility. General improvements in housekeeping are also recommended.
