Abstract
In response to a request from the United Steelworkers of America, an investigation was made of possible hazardous working conditions at Union Tank Car (SIC-4789), Cleveland, Texas during railroad tank car repair. Respiratory irritation had been reported by several workers. The company refurbishes, repairs and performs routine maintenance on railroad tank cars. There were 237 full time employees at the time of the first of two site visits; there were 164 full time employees at the time of the second visit. During arc gouging, welding, cutting and interior sweeping on railroad tank cars, workers were exposed to levels of arsenic (7440382), iron (7439896), nickel (7440020), and nitrogen-dioxide (10102440) which constituted a health hazard. Potential hazards also existed in exposures to isocyanates, chromium (7440473), and asbestos (1332214). Urine tests suggested occupational exposure to arsenic. The authors conclude that health hazards existed during arc gouging, welding, cutting and interior sweeping on railroad tank cars; during car maintenance activities, potential hazards existed from exposures to contaminants. The authors recommend that engineering controls, improved respiratory protection, and administrative controls be instituted to prevent both routine overexposures and acute exposure incidents.
