Area samples were analyzed for carbon-monoxide (630080) at the Interchurch Center (SIC-8661), New York, New York in June, 1984. The survey was requested by the Administration of the center and the staff association of the National Council of Churches due to complaints of headache and dizziness occurring among employees. The ventilation system was evaluated. Carbon-monoxide concentrations were well below the OSHA standard of 50 parts per million. The ventilation survey showed that the supply of air to the floors was not balanced. During the ventilation survey, a black, viscous substance was found on the frosted glass coverings of the fluorescent light fixtures, leaking from the light ballasts. Samples of the substance were analyzed and found to contain polychlorinated biphenyls (PCBs). The author concludes that the PCBs in the light fixtures do not constitute a health hazard due to the inaccessibility of the fixtures. He recommends that the ballasts in the fixtures be replaced with ballasts that do not contain PCBs. The ventilation system should be balanced, and truck drivers should be prohibited from idling their engines while parked in the loading area near the air intakes on the south side of the building.
