An environmental evaluation of possible chemical contamination, ventilation, temperature and humidity, and illumination levels was conducted at Appalachian Laboratory for Occupational Safety and Health, Morgantown, West Virginia in October 1981. An official request for the survey was made by 3 employees on behalf of 240 workers, because of throat irritation and eye strain complaints. Ventilation, temperature and humidity, and illumination levels were evaluated. Possible effects of microbial or gross chemical contamination were considered. Medical questionnaires were administered. No overexposures to chemicals were found. Airborne microbial populations were very low. Air contaminated by stacks was often recirculated in the building air supply. Ventilation fans were often very dirty. Humidity readings below 20 percent were recorded on several occasions. Lighting levels were often below 75 foot candles. Effects of cigarette smoke and use of video display terminals were not evaluated. Eye irritation, headache, backache, and nervous tension were the main symptoms thought to be job related. Fifty percent reported onset of symptoms within 2 hours of entering the building. The authors conclude that worker symptoms may be related to inadequacies noted n the work environment. Improved ventilation, increased lighting, and maintenance of optimum humidity are recommended.
