In response to a request from the Superintendent of Schools for Marion County, West Virginia an investigation was conducted on the ventilation in the Blackshere Elementary School (SIC-8211) due to reports by teachers and students of symptoms such as fatigue, eye irritation, nasal congestion, and headache. Telephone interviews were conducted with 70% of the 33 teachers and questionnaires were completed by the 47 staff and faculty members at the school about the presence of symptoms while at work. Air samples were collected at various locations around the school and the heating, ventilation, and air conditioning systems were evaluated. Symptoms associated with being in the school building were reported by 47% of the employees. Sixty three percent of the employees reported too little air movement in the building and 66% reported problems with the temperature. Carbon-dioxide concentrations exceeded 1,000 parts per million, indicating that there may have been insufficient outside air provided to occupied spaces. The authors conclude that a health hazard did not exist at the time of the evaluation. The authors recommend that the ventilation system be modified to provide sufficient outside air to occupied spaces.
