Environmental and breathing zone samples were analyzed for xylene (1330207) hexavalent-chromium (18540299) (Cr-VI), metallic chromium (7440473) (Cr), lead (7439921) (Pb), and zinc (7440666) (Zn) at the Westinghouse Electric Corporation (SIC-3613), St. Louis, Missouri in May 1983. The evaluation was requested because of employee concern about exposure to hazardous chemicals on the paint line. Airborne xylene concentrations ranged from 0.9 to 14 milligrams per cubic meter (mg/m3). The OSHA standard is 435mg/m3. The air concentration of the metals was: Cr, 0.077 to 0.93mg/m3; and Zn, 0.333 to concentrations ranged up to 0.011mg/m3. The OSHA standard for Cr-VI is 0.1mg/m3 and the American Conference of Governmental Industrial Hygienists standard for Zn is 5.0mg/m3. Twelve exposed and 11 nonexposed employees were interviewed and urine and serum samples were collected. Urinary methylhippuric-acid (2198643) concentrations were low, indicating low exposure to xylene. Serum samples showed no significant difference in liver function abnormalities between the two groups. The authors conclude a health hazard did not exist on the paint line. They recommend that a program of worker education be instituted and that respirators in the paint shop be carefully maintained.
