Exposures to carbon-monoxide (630080) (CO) and particulates from welding operations and diesel emissions were surveyed in February 1982 at Honda Motor Company of America (SIC-1541), Marysville, Ohio. Evaluation was requested by an unspecified source on behalf of 250 workers. Samples were collected for CO, welding fumes, total particulates, and particulates of iron (7439896), lead (7439921), nickel (7440020), zinc (7440666), beryllium (7440417), and copper (7440508). Medical questionnaires and blood carboxyhemoglobin tests were given to 65 workers. Total particulate and metal particulate concentrations were all below acceptable limits. Three personal air samples for welding fumes exceeded the American Conference of Governmental Industrial Hygienists' Threshold Limit Value of 5 milligrams per cubic meter; no OSHA standard exists. CO concentrations ranged from 0 to 33 parts per million (ppm) for personal samples and 5 to 42ppm for area samples, all below the OSHA 50ppm limit. Twenty four workers had symptoms consistent with CO poisoning. Mean carboxyhemoglobin concentrations increased significantly over the work shift, and the increases were correlated with measured personal CO exposures. The authors conclude that no over exposures to CO or welding fumes exist; however, some workers have experienced symptoms compatible with CO intoxication. Improved ventilation and approved respirators are recommended.
