Health-hazard evaluation report HETA 84-248-1694, Wasson Elementary School, Dubois, Pennsylvania
The DuBois area school district DuBois, Pennsylvania requested an evaluation due to complaints of bloody nose, dry eyes, upper respiratory irritation, and headaches among students and faculty at the Wasson Elementary School. All 24 teachers were involved in a questionnaire that focused on medical histories and symptoms related to working in the school. Environmental air samples revealed trace concentrations of organic vapors, primarily toluene and C9 to C12 hydrocarbons. Carbon-dioxide levels measured 200 parts per million (ppm) outside and up to 800 ppm inside, suggesting that the amount of fresh air coming into the building was inadequate. The distribution of that air within the building was inadequate. The authors conclude that the health complaints were related to poor indoor air quality caused by deficiencies in the ventilation system. The heating/cooling system had many deficiencies related to design, installation, and maintenance. The authors recommended improvements to be made in the system, including cleaning air filters, adjusting dampers, leaving classroom doors open, using fans to promote mixing of outside air, and setting thermostats at the same setting.
