Results of an indoor air pollution investigation.
After the opening of a new elementary school in fall 1986, several members of the school's staff noticed symptoms they attributed to the workplace. An investigation by the Occupational Safety and Health Branch (OSHA) of the Alaska Department of Labor found no major health problems and concluded that fireproofing at the school may have caused a petroleum-like odor. In fall 1987, parents reported illness in their children that they attributed to school attendance. Subsequent epidemiologic investigation found that student and staff absentee rates were not increased and were similar to other schools in the district. Testing conducted by the National Institute for Occupational Safety and Health (NIOSH) confirmed that the petroleum-like odor was due to the fireproofing. Toxicologic information and the results of air sampling confirmed that no adverse health effects would be expected from the product. By working together with NIOSH, OSHA, the school district, and a consulting mechanical engineer, deficiencies in the school's ventilation system were discovered and immediately corrected with interim engineering changes. Only by bringing multiple agencies together and openly sharing findings with concerned parents and staff were the problems at the school resolved.
