Environmental and breathing zone samples were analyzed for total particulates, trace metals, glycol ethers, and other organic materials at Hydra/Matic, a division of General Motors (SIC-3714), in Ypsilanti, Michigan in March, 1984 and March, 1985. The evaluation was requested confidentially to investigate employee exposures to machine coolants and additives used in the centerless grinding operation. The central coolant system had been contaminated by sewage and high concentrations of chemicals had reportedly been added to the system to prevent bacterial growth. Questionnaire interviews were conducted with 75 employees. Eye irritation, sinus congestion, rhinitis, daily cough, upper respiratory infections, and skin complaints such as frequent dryness, itching, rash, and pimples were reported. All concentrations of chemical agents were below their relevant standards or not detectable. The authors note that no airborne contaminant that would pose a health hazard has been identified. Recommendations include properly maintaining the coolant system and individual machines, training employees in proper work practices for use with cutting fluids, and making barrier creams and protective clothing available.
