This report updated information previously published on the indoor air quality investigations conducted by NIOSH since 1971. Through December of 1988, there were 529 NIOSH indoor air quality health hazard evaluations performed. Most were conducted in government and private office buildings. In most cases the symptoms and health complaints reported were not specific enough to easily identify the causative agent. The implication of the workplace was generally based on the fact that the symptoms abated while the workers were absent from the site. From 1983 through 1988, the frequencies with which NIOSH saw the major contributors of poor indoor air quality had not dramatically changed. In 15% of the investigations, contamination generated by sources inside the office space was the major problem, with copy machines being a significant source. In 10% of the studies, contamination from sources outside the office space was the major problem including motor vehicle exhaust, boiler gases, and previously exhausted air. As concern increases for a healthy and comfortable work place, on the part of office workers, there is an expected increase in the frequency of requests for such studies.
