In response to a request from a union, the Princeton Association of Classroom Educators (PACE), a study was undertaken of possible hazardous working conditions at the Princeton High School (SIC- 8211), Cincinnati, Ohio. The school building housed about 2,000 students and 200 staff. Faculty and students reported allergy and asthma problems, along with irritation of the nose, throat, and eyes. When not in the building, their symptoms subsided. A medical questionnaire was distributed and an environmental evaluation was begun of two areas in the school, the office area and one of the classroom wings. One or more symptoms, which decreased when absent from the building, were reported by 57% of those completing the questionnaire. Carbon-dioxide (124389) levels exceeding 1,000 parts per million were noted in the evaluated classroom wing, suggesting an inadequate supply of outside air. Inspection of the air handling equipment revealed a significant amount of microbial growth on the drain pans. The author concludes that some environmental deficiencies were identified, as well a major problem with ventilation system maintenance. The author recommends that the air supply system be cleaned up, and its performance improved.
