United Automobile Workers Local 338 requested an evaluation of respiratory and skin problems among workers at TRW Bearings Division Facilities (SIC-3562), Jamestown and Falconer, New York. The facilities grind and mill roller bearings for the automotive and aircraft industry. A free running synthetic coolant (usually a 1:25 coolant:water mixture) was used to reduce heat build up within the bearing and the grinding wheel. The coolant systems in both facilities consisted of primarily oil fractions of aliphatic hydrocarbons, phenols, and nitrogen compounds. The microbiocide used contained several isothiazolin and chloro-nitrogen compounds. The rust inhibitor showed no major peaks under gas chromatographic, mass spectrometric analysis. Airborne exposures to oil mist or other substances were not in excess of current occupational health criteria. The authors conclude that the reason for the higher prevalence of skin problems is not clear. The authors recommend that careful attention be given to the wearing of clean work clothes, adequate gloves and use of barrier creams. Workers should shower at the end of the day. Solvents should not be used for cleansing the skin. A skin reconditioning cream should be used. Cuts and scratches should be washed and covered by a dressing. Short sleeved overalls should be worn to reduce friction from cuffs saturated with oil and swarf. Eating at the worksite should not be allowed.
