• Description:
  In response to a request from administrators at the Tri-County North (TCN) Local School System (SIC-8211), Lewisburg, Ohio, a follow back evaluation was conducted after ventilation changes had been made, and the ventilation system had been tested and balanced. Carbon- dioxide (124389) levels, temperature, relative humidity, formaldehyde (50000), and total volatile organic compounds were measured. Carbon-dioxide levels exceeded 1,000 parts per million (ppm) in some classrooms. Formaldehyde levels ranged up to 0.019ppm in the classrooms as time weighted averages (TWAs). Total volatile organic compound concentrations of 3.7 and 4.4mg/m3 were detected in two of eight general area samples, near photocopiers. The author concludes that a health hazard was not identified during this evaluation. Indoor environmental quality has continued to improve since the initial evaluation conducted in 1992. The author recommends that the photocopiers which use liquid toner be replaced, or local exhaust ventilation be used in the area. Some classrooms still did not provide the recommended 15 cubic feet of outside air per person.
