Evaluation of Indoor Environmental Quality Concerns in an Elementary School

Health Hazard Evaluation Report 2017-0030-3277

NIOSH staff evaluated indoor environmental quality in an elementary school building.

Findings:

  • We saw no widespread mold or water damage.
  • Carbon dioxide levels were high in some classrooms, meaning that the ventilation did not provide enough outdoor air throughout the school day.
  • Some symptoms reported by employees have been associated with inadequate ventilation; these types of symptoms are also common in the general population.
  • Cancer and other medical conditions reported by some employees are not related to exposures in the school.
