Abstract
In response to a request from the National Treasury Employees Union, an investigation was undertaken of indoor environmental quality (IEQ) at the Internal Revenue Service Office (SIC-9311), Flint, Michigan. Employees had reported sinus problems, cold like symptoms, and headaches. The indoor carbon-dioxide (124389) concentrations measured were all below the recommended level of 1,000 parts per million. Temperature and relative humidity levels were within seasonal suggested guidelines. Evidence of microbial growth was found in the lined condensate pan of the heating, ventilating and air conditioning unit. There was a potential for vehicle exhaust to enter the building; the below ground outside air intakes were located adjacent to a parking lot. Employees were permitted to smoke in a storage area which formed part of the recirculating air system that served the entire basement area. The most common concerns of the workers included temperature extremes, lack of humidity, and lack of movement of the air. Stuffy or runny nose or sinus congestion, tired or strained eyes, unusual tiredness, fatigue, drowsiness, and dry itching or irritated eyes were the most frequently reported complaints. The authors conclude that environmental tobacco smoke was a health hazard in this location. Other problems identified include microbial growth in the condensate pan and the potential for vehicle exhaust entrainment by the ventilation system. The authors recommend that steps be taken to improve the indoor air quality and eliminate environmental tobacco smoke in the workplace.
