An industrial hygiene survey was conducted at the Unit Parts Company, Oklahoma City, Oklahoma in January, 1973. The survey was requested by the manager of Employment, Security, and Safety to determine if possible health hazards existed and if the company was in compliance with OSHA standards. Environmental and breathing zone samples were analyzed for total dusts and metal fumes, asbestos (1332214), and organic solvent vapors. Measurements for noise and environmental heat stress were also made. Total airborne dust samples ranged from 0.44 to 53.50 milligrams per cubic meter (mg/m3). The federal standard for total dust is 15mg/m3. The armature burnout vibration and undercutting operations had copper (7440508) dust concentrations in excess of the federal standard of 1mg/m3. All asbestos concentrations were below the federal standard. Toluene (108883) concentrations at the vinyl dip tank and isopropyl-alcohol (67630) concentrations at the brake shoe cleaning area exceeded the federal standards of 200 and 400 parts per million, respectively. Noise measurements showed several areas exceeding the federal standard of 90 decibels. Measurements for heat stress indicated no hazard. Recommendations include redesign or elimination of armature burnout operations, improved ventilation, and establishment of an effective hearing conservation program.
