In response to a request from a representative of Local 248 of the United Auto Workers, an evaluation of possible health hazards was made at the Allis-Chalmers Corporation (SIC-3321), West Allis, Wisconsin. Air samples were analyzed for free crystalline silica (7631869), carbon-monoxide (630080), and nickel (7440020), each of which was found to be present in excessive amounts in several areas of the facility. A second followup survey measured concentrations of metal fumes, dimethylethylamine (75649), carbon-monoxide, and methylene-bisphenyl-isocyanate (101688) (MDI). Exposures to respirable crystalline silica, nickel and carbon-monoxide exceeded the NIOSH recommended standards. Of the 67 workers for whom occupational histories and chest x-rays were available, six had silicosis, including one case of silicotuberculosis. One other pneumoconiosis case was also found. Symptoms of recent upper respiratory symptoms were noted in 75 percent of the workers. Nine showed abnormal pulmonary function tests. The authors conclude that health hazards exist due to excessive exposure to free crystalline silica in the core making and cleaning department, carbon-monoxide in the old coke fired cupolas and pouring areas and to nickel in the finishing area. The authors recommend that engineering controls, monitoring, and medical management be improved.
