Exposures to carbon-monoxide (630080) (CO) nitrogen dioxide (10102440) (NO2), and nitric oxide (10102439) were surveyed at the United States Secret Service (SIC-7525) Department of the Treasury, vehicle garage in Washington, D.C., on October 28, 1976. The survey was requested by the Chief of Administrative Operations Division, United States Secret Service, Department of the Treasury on behalf of an unspecified number of garage employees. Breath analyses for 7 workers revealed elevated carboxyhemoglobin (COHb) concentrations, but only 2 exceeded the OSHA standard of 50 parts per million, and these were found in heavy smokers. Nonsmokers did not exceed criteria, but did have elevated COHb. In air, CO concentrations were well within OSHA standards of 50 parts per million for an 8 hour time weighted average. No detectable concentrations of nitrogen dioxide or nitrous oxide were found. The author recommends that malfunctioning garage doors be repaired, outside air intake be kept clear of debris, automobiles be prohibited from parking at the outside air intake, local exhaust system be used when cars are serviced, and an inspection, test and evaluation of the ventilation system be performed to ensure its optimum operation.
