The Texas City disaster was the deadliest industrial accident in U.S. history. The incident took place on April 16, 1947, and began with a mid-morning fire on board the French-registered vessel SS Grandcamp which was docked in the Port of Texas City. The fire detonated approximately 2,300 tons of ammonium nitrate[1] and the resulting chain reaction of fires and explosions killed at least 581 people, including all but one member of the Texas City fire department.[2] These events also 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.
