Short title	A primary vessel explosion lifts building dust into a cloud that ignites in a secondary explosion.
Image title	Building cross-section. Left: a process vessel fails in a primary explosion; flame and a blast wave leave the vessel. The blast and airflow cross the room and lift dust deposited on the floor and on a beam. Right: the resuspended dust cloud ignites in a larger secondary explosion that fills much of the building and loads the roof and walls; an occupant leaves through a door away from the hazard.
