In response to a request from the National Park Service, a survey was made to identify asbestos (1332214) containing materials at Denali National Park and Preserve (SIC-9441), Denali, Alaska. A total of 108 samples of building materials and maintenance parts were taken for analysis. The polarized light microscope was used on site to identify the majority of the asbestos containing materials and pin point their locations. Asbestos was found in 46 samples; 82 percent of these samples were related to insulation materials for wrapping pipes and boiler/hot water tanks. The other positive tests were for gasket materials or transite board. In general the insulation was in good repair with only minor areas needing wrapping or plastering. Unless the asbestos became damaged, its removal could be delayed and associated with building repair or renovations. The author concludes that asbestos exposure to the general workforce and residents is minimal. Those pipes with insulation that was not in good shape were identified so that recommended action could be taken to remove the hazards.
