Environmental and personal air samples were analyzed for total welding particulate, iron (7439896), zinc (7440666), copper (7440508), chromium (7440473), and carbon-monoxide (630080) at the Hendrickson Manufacturing Company (SIC-3711), in Lyons, Illinois, in March and May, 1980, and in February, 1981. A representative of the United Steel Workers of America, Local 4336, requested the evaluation on behalf of approximately 35 affected workers. Eight hour time weighted average (TWA) personal exposures to total welding fume particulates ranged from 1.0 to 3.5 milligrams per cubic meter (mg/cu m) with a mean of 2.5mg/cu m, compared with the recommended limit of 5mg/cu m. Eight hour TWA personal exposure to iron-oxide fume ranged from 0.26 to 1.24mg/cu m, compared with the OSHA standard of 10 mg/cu m. Personal exposures to zinc-oxide and copper were well below the environmental criteria. Chromium was not detected in the samples. Instantaneous concentrations of carbon- monoxide did not exceed the recommended 15 minute ceiling limit of 200ppm. Two workers reported sinus problems, shortness of breath, and dizziness. The author concludes that a health hazard from the sampled substances did not exist at this facility. He recommends the installation of local exhaust ventilation systems, welder education, and use of barrier curtains to prevent eye injuries.
