Abstract
In response to a request from the National Labor Relations Board (NLRB), an investigation was made into possible poor indoor environmental quality at the NLRB offices in the John Weld Peck Federal Building (SIC-9651), Cincinnati, Ohio. During a 2 week period, workers in the southeastern and southwestern corridors experienced severe headaches on several consecutive days. Due to the appearance of the Air Handling Unit (AHU) 3 that serves a particular office where there had been complaints, samples were taken of liquid from the condensate pan, scrapings from the east wall of the AHU 3, downstream from the cooling coils, and insulation from the north side of AHU 3 at the cold duct entrance. Scum was also sampled from the cooling coil eliminators. Thermophilic actinomycetes was isolated from samples collected in the AHU. The authors conclude that clear evidence was not found that employees' headaches were caused by building contaminants. The authors recommend that various factors of the air handling system be corrected as they may result in microbial growth.
