Environmental and medical surveys were conducted on December 21, 1977, and March 28 and 29, 1978 to investigate illnesses among employees from the welding and painting operations at Chalfant Manufacturing Company (SIC-3443) in Elyria, Ohio. The evaluation was requested by an authorized employee representative of the Upholsterer's Union Local 48 on behalf of the approximately 11 affected employees. Samples analyzed for zinc-oxide (1314132), aluminum (7429905), iron-oxide (1309371), cadmium (7440439), xylene (1330207), acetone (67641), and beryllium (7440417) were below evaluation criteria. Copper (7440508) fume concentrations ranged from 0.1 to 1.5 milligrams per cubic meter (mg/m3), exceeding the OSHA standard of 0.1mg/m3, and total dust concentrations ranged from 12.4 to 18.2mg/m3, exceeding the OSHA standard of 15mg/m3. Ozone concentrations ranged from 0.005 to 1.0 parts per million (ppm) during welding, exceeding the OSHA standard of 0.1ppm. Interviewed workers reported work associated symptoms, with worse symptoms when the welding process involved galvanized steel. The authors conclude that a health hazard exists for the welders, and spray painters may have been exposed to excessive solvent vapors when painting in poorly ventilated areas. They recommend that local exhaust ventilation be installed in all welding locations and that welding curtains be installed to protect other workers from flash burns.
