Volcanic ash consists of fine particles of rock, minerals, and aerosol droplets produced by explosive volcanic eruptions. Drifting ash can contaminate large volumes of airspace and threaten the safety of aircraft in flight. Ashfall on aerodrome facilities will affect airport runways, taxiways and aprons, buildings, grounds, services, electrical utilities, aircraft on the ground, and communications facilities. Returning to normal service following an ashfall can be difficult. The workshop covered in this volume was convened to exchange information about proper removal and containment of ash. The meeting included technological presentations covering experiences with cleanup at airport facilities and discussions in four working groups that addressed surfaces, electronics and communications systems, emergency services, and airplanes and support vehicles
