Environmental and breathing zone samples were analyzed for carbon- monoxide (630080) at Distribution and Auto Services, Incorporated (SIC-9999), Benecia, California in March, 1985. The evaluation was requested by a union representative due to complaints of headaches, drowsiness, and nausea from employees in the air conditioning shop. It was believed that either exhaust fumes or rust inhibitor burn off was causing the symptoms. Three workers were interviewed to determine the extent of their medical complaints. Carbon-monoxide concentrations ranged from 2 to 5 parts per million (ppm) in the shop and 4 to 5ppm in a paint spray booth. The NIOSH standard for carbon-monoxide is 35ppm. Workers complained about dizziness, headache, nausea, and lightheadedness. A haze and bad odor were reported to emanate from the vehicles while their air conditioning systems were being tested. The author concludes that the employees are not overexposed to carbon-monoxide. He recommends that vehicle air conditioning testing be done outdoors, or two unused spray paint booths be utilized for that purpose. The spray paint booth exhaust fan should be cleaned periodically to prevent the accumulation of the oily residue burn off seen on exhaust fans in the shop.
