In response to a request from Matrix Auto Body (SIC-7531), Englewood, Colorado, an assessment of worker exposures to isocyanates during automobile spray painting was conducted. Specific concerns were expressed involving solvent exposure, total dusts, noise, carbon-monoxide (630080) and metals. The autobody repair shop performed frame straightening, panel repair and replacement, body filling, painting, and detailing. Repairs were conducted in an open shop with painting performed in a separate part of the building. None of the air samples for solvents exceeded acceptable levels. The mixture summations of all organics for all samples during both sampling periods were not in excess of any evaluation criteria. Area total dust samples ranged from 3.5 to 26mg/m3 of air. Most of these samples were collected in the paint booth. Personal breathing zone total dust samples ranged from 4.1 to 35mg/m3 for short periods. For carbon-monoxide, the peak concentration was 247 parts per million, and concentrations averaged 54 parts per million. The average noise exposure level was 94.4 decibels-A, resulting in a 185% dose of the maximum allowable noise exposure. Exposures to all metals were well below the respective evaluation criteria. The author concludes that a potential health hazard existed from exposure to peak levels of carbon-monoxides during cold weather.
