Hazard Evaluations and Technical Assistance Report No. TA-79-15 at Dulles International Airport, Washington National Airport, Washington, D.C.
NIOSH 1979 Apr:21 pages
Exposure to asbestos (1332214) fibers at Dulles International Airport (SIC-4582) and at Washington National Airport were measured from January 15 to 17 1979. The survey was requested by the Federal Air Surgeon. Bulk samples of ceiling material, floor sweeping and direct insulation were analyzed for presence of asbestos fibers. Twenty five general area air samples were taken at Dulles airport and 12 at Washington National Airport. The ceiling material at Dulles contained 40 to 50 percent chrysotile (12001295) asbestos. Material at National contained 1 to 2 percent chrysotile-asbestos. No asbestos fibers in bulk samples of sweepings and no detectable concentrations of airborne asbestos fibers were found at either Dulles or National. One ventilation duct contained 40 percent chrysotile amosite (12172735) asbestos. The authors conclude there is no health hazard from exposure to asbestos fibers at either airport. They recommend monitoring air and dust at Dulles and dust at National to detect future deterioration of the ceilings. The asbestos containing duct wrapping should be covered and consideration be given to replacement.
