The Texas City disaster of April 16, 1947 is the deadliest industrial accident in U.S. history, and one of the largest non-nuclear explosions. Originating with a mid-morning fire on board the French-registered vessel SS Grandcamp (docked in the Port of Texas City), its cargo of approximately 2,300 tons (approximately 2,100 metric tons) ofammonium nitrate detonated,[1] with the initial blast and subsequent chain-reaction of further fires and explosions in other ships and nearbyoil-storage facilities killing at least 581 people, including all but one member of the Texas City fire department.[2] The disaster triggered the first ever class action lawsuit against the United States government, under the then-recently enacted Federal Tort Claims Act (FTCA), on behalf of 8,485 victims.
