Atmospheric samples were analyzed for methyl-ethyl-ketone (78933), methyl-isobutyl-ketone (108101), toluene (108883), butyl-acetate (123864), cyclohexanone (108941), trichloroethylene (79016), oil mist, sulfuric-acid (7664939), nitric-acid (7697372), chromium (7440473), total particulate weight, aluminum (7429905), silver (7440224), copper (7440508) and ozone (10028156) and 24 employees were interviewed at Western Gear Corporation (SIC-3761), Flight Structures Division in Jamestown, North Dakota from June 5 to 8, 1978. An unidentified individual from the Corporation requested the evaluation on behalf of 150 affected production workers. Twenty four employees were administered questionnaires to obtain occupational histories. Worker exposures to organic vapors, acid mists and metal fumes were below OSHA standards. The author concludes that the employees are not exposed to hazardous chemical concentrations, however a potential overexposure to aluminum welders may exist from ozone gas. They recommend modifications to the exhaust ventilation system, the use of proper respirators and avoidance of contact with polymeric isocyanate foam.
