HHE determination report no. HHE-73-185-256, Electromotive-Division GMC (Plant 2), Chicago, Illinois.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 73-185-256, 1976 Jan; :1-25
A Health Hazard Evaluation investigation was conducted by NIOSH on May 16, July 15-18, and October 15-16, 1974, and June 25, 1975 at the Electro-Motive Division, GMC, Plant 2, Chicago, Illinois, a manufacturer of diesel locomotive components (SIC-3743). The survey was prompted by a request from an authorized representative of the 276 affected workers regarding lack of ventilation in the welding areas, which allegedly did not remove welding fumes. On the basis of the findings obtained in a random sample of workers, it was determined that some welders were exposed to concentrations of iron- oxide (1317619) fumes. Welders were not exposed to toxic concentrations of carbon-monoxide (630080), ozone (10028156) and nitrogen-dioxide (10102440). The presence of eye and respiratory irritation in the 8 departments working the day and evening shift indicates that an irritant exposure takes place. Possible synergistic effects developing from the combination of irritant gases and particulates are contemplated. The potentially toxic exposure to carbon-dioxide in one area could have been responsible for the high incidence of headaches. No evidence of systemic toxicity was observed. Recommendations are made for improved environmental control measures.
