Technical assistance report no. TA-79-52, Federal Office Building No. 6, Washington, D.C.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, TA 79-52, 1979 Nov; :1-15
Temperature and humidity, and carbon-monoxide (630080), carbon- dioxide (124389), and dust concentrations were measured, air handling systems were monitored and interviews were conducted with occupants and operating engineers of Federal Office Building number 6, Washington D.C. The evaluation was requested by the Health, Education, and Welfare Office of Education, on behalf of an unspecified number of occupants to determine whether harmful airborne contaminants were present. Nuisance particulate concentrations were less than 0.5 milligrams per cubic meter (mg/cu m), carbon-dioxide was present in only trace amounts, and carbon- monoxide was undetectable. All were within the acceptable OSHA criteria of 10mg/cu m, 30,000 parts per million (ppm), and 200ppm, respectively. Several deficiencies were observed in the operation, maintenance, and equipment of the air handling system and the occupants reported numerous complaints of illness and discomfort. NIOSH determined that no hazardous chemical concentrations were present during the test period. They recommend that the air handing system be improved, and that clinical reports of illness be periodically reviewed. The basement garage also should be monitored as a potential carbon-monoxide source.
