A health hazard evaluation was conducted at the Smithsonian Institution (SIC-8411), Washington, DC in July 1976. Atmospheric samples were collected to measure asbestos (1332214) in ceiling materials at various facilities. Bulk, area, and personal samples were collected. Fibers greater than 5 microns in length were counted. Of the 77 samples, 72 were below analytical limits of detection. Concentrations of the remaining samples ranged from 0.03 to less than 0.01 fibers per cubic centimeter. The percent composition of asbestos was determined in 32 bulk samples, 30 of which were from ceiling scrapings. Asbestos content ranged from nondetectable to approximately 75 percent. The author concludes that it is unlikely that personal exposures pose significant risks. The author recommends vacuuming of areas where fibers could accumulate, sampling for asbestos when environmental conditions of work practices change, and use of appropriate sealants on asbestos ceiling materials. Personal sampling should be conducted during maintenance procedures, adequate respirators should be worn during maintenance, and the ventilation system should be monitored.
