In response to a request from the Kentucky Labor Cabinet, an evaluation was carried out at the South Campbell County Middle School, (SIC-8211), in Alexandria, Kentucky to determine possible exposures to stagnant water, excessive mold growth, and imbalances in the ventilation system. Inside the school the relative humidity levels in December ranged from 28 to 32 percent. Levels of carbon- dioxide (124389) were determined to be 1500 parts per million, four to six times higher than outdoor levels. Water had seeped under the gymnasium floor, causing cracks in the interior and exterior walls. Problems were identified with the ventilation including poor maintenance, improperly set controls, and improper design. Results of medical questionnaires indicated that the staff at this school was three times as likely to develop respiratory symptoms as the staff at a nearby school. A significant association was found between any exposure to the library lasting at least 1 hour per week, and the development of respiratory illness. The authors recommend that carpet be removed from areas of the school where it was not needed for noise control or where it would be exposed to stagnant water; alteration of carpet shampooing practices to insure that carpets do not remain damp over vacations or at other times when the lights were turned off and the temperatures not controlled; adherence to approved maintenance procedures; and proper maintenance of temperature, humidity, and ventilation in the library.
