Abstract
Environmental and medical surveys were conducted on April 4 to 7, 1977, and June 7 to 9, 1977, to determine employee exposures to dust fumes, smoke and gases from welding and plasma arc cutting, isocyanate (661201) vapors and x-ray radiation at the General American Transportation Corporation (SIC-3743) in Masury, Ohio. Authorized representatives of United Steelworkers of America, Local 1534 and 2318, requested the evaluation on behalf of approximately 1000 affected workers. Twenty four of 52 employees were exposed to concentrations of fluoride (16984488), copper (7440508), iron-oxide (1309371), nickel (7440020), chromium-VI (7440473), vanadium (7440622) and total particulates in excess of OSHA standards. Concentrations of carbon-monoxide (630080), formaldehyde (50000) and polymethylene-polyphenyl-isocyanate (9016879) also exceeded current OSHA exposure limits. No abnormalities other than abrasions and burns associated with welding and heavy metal handling were found. The author concludes that excessive contaminant emissions are produced from welding, air arc repairing, chipping and gouging, bank cleaning and grinding. Local ventilation should be instituted to control excessive emissions, respiratory protection should be used, fibrous glass insulation treated with resin materials and used to seal annealing furnace doors should be substituted with a safer material, undue exposure to isocyanates should be avoided when handling urethane foams, and continuous surveillance should be maintained on all radiography equipment.
