A hazard evaluation and technical assistance survey of levels of airborne asbestos (1332214) at the Smithsonian Institution's Silver Hill, Maryland, Tract B facilities (SIC-9999) is reported. A total of 36 personal and general area air samples were collected on millipore filters. Samples were taken during separate time periods under three conditions: 1) the undisturbed building; 2) during simulated rain; and 3) after simulated rain. In an undisturbed empty condition, except for one location, there was no detectable airborne asbestos during a 2 hr sample. However, when a 30 to 45 min rain was simulated by fire hoses, there was a significant increase in airborne asbestos fiber concentrations. Two hours after the simulation, monitoring of routine janitorial tasks showed the employees exposure to be 80 percent of an 8 hr time weighted average daily exposure criteria. It is concluded that a potential health hazard exists for anyone who may have to work in the Smithsonian Institution's Silver Hill buildings.
