Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HETA 82-177-1287, 1983 Apr; :1-12
Ventilation was inspected, employees were interviewed, detector tube readings were taken for carbon-monoxide (630080) (CO) and carbon- dioxide (124389) (CO2), and air flow, temperature, and humidity were determined at American Savings (SIC-6023) in Honolulu, Hawaii, on July 26 through 30, 1982. A request for the survey was made by a management representative because of complaints among persons in the building including headaches, stomach problems, respiratory problems, twitching of the eyes, and other neurological disorders. Concentrations of CO2 ranged between 0.06 to 0.08 percent, while the outside concentration was about 0.03 to 0.04 percent. Concentrations of CO on the upper floors were about 3 to 4 parts per million (ppm) all day and 4 to 5ppm at the street intake location in the afternoon. There was adequate air circulation to keep the building air well mixed. Cooling on the upper floors was insufficient, especially on Monday mornings. Solvent vapors were introduced into the ventilation system. The authors conclude that workers were suffering adverse health effects which were probably caused by poor air quality. They recommend starting the ventilation system earlier in the morning, introducing additional fresh air, moving maintenance from the basement, and locating a fresh air intake at the roof of the building.
