Health Hazard Evaluation Report No. HETA 82-023-1136, National Institute of Mental Health, Rockville, Maryland

摘要

Employees had complained of increased frequency of headaches, short-term memory loss, frequent transposition of numbers, general congestion, a systemic feeling of malaise, and other illnesses. On February 18, 1982, a NIOSH investigator conducted an environmental survey. Analysis of the samples for non-specific volatile organic compounds showed higher-chain C9-C12 alkanes to be present in or at concentrations of approximately 3.5 milligrams per cubic meter (mg/cu m3). NIOSH investigators concluded that no health hazards existed at the time of the survey. Relative humidity was measured to be at levels less than comfortable and air flow patterns were interrupted by room partitions. A ventilation engineer should be enlisted to determine the adequacy of supply and exhaust air for the offices in question.
