Information was presented to aid employers and employees in evaluating indoor air problems. The report was divided into three sections. The first dealt with information gathered through the experience of the authors with indoor air quality problems and delineated some of the more significant causes of these problems. This information was gathered through a background assessment, initial site visits, walk through evaluations, personal interviews, environmental monitoring and followup site visits. Specific causes discussed include inadequate ventilation, inside contamination, outside contamination, microbiological contamination, and building fabric contamination. The second part was a self help approach to assist the reader in evaluating an indoor air quality problem. Such an evaluation would require input from complaints which must be documented; a characterization of the building; walk through surveys; attention to carbon-dioxide (124389) levels, humidity, and temperature; estimation of the provision of adequate amounts of outside air; and elimination of all sources of contamination. The third section listed sources to which the reader can turn, in addition to NIOSH, for assistance if self evaluation is not successful in resolving the problems. These sources include governmental (state and local) agencies, private consultants, the U.S. EPA, the Consumer Product Safety Commission, the Office of Scientific and Technical Information, and the Federal Employee Occupational Health Program.
