Employee exposures to carbon-monoxide (630080), carbon-dioxide (124389), and sulfur-dioxide (7446095) were evaluated at Case Power and Equipment (SIC-7538) in Bolingbrook, Illinois on January 21, 1982. The request came from the company management after an employee had become ill and others complained of nasal irritation, chest pains, and headaches. Questionnaires were administered to employees, and area air and breathing zone samples were collected. Time weighted average (TWA) concentrations for hydrocarbons and carbon-dioxide were below OSHA standards. No detectable concentrations were found for sulfur-dioxide. The TWA concentration for carbon-monoxide was 49 parts per million (ppm), with the OSHA standard set at 50ppm, and the NIOSH recommendation set at 35ppm. The author concludes that a potential health hazard exists due to elevated carbon-monoxide concentrations and inadequate ventilation. He recommends balancing of the ventilation system. Welding should be conducted behind flame resistant screens, and under adequate ventilation conditions.
