In 1947, the Port of Texas City lost all but one of its firefighters when a ship's cargo of 2300 tons of ammonium nitrate detonated with an explosive yield estimated between 2.7 and 3.2 kt. The fire got going around 8 am, but the ammonium nitrate didn't go up until 9:12, thus allowing the firefighters plenty of time to get too close.
Reminds me of this History Channel show.
