1973 Staten Island gas explosion

About

On February 10, 1973, a gas explosion occurred inside a Texas Eastern Transmission Pipeline tank storing liquefied natural gas in the Bloomfield neighborhood of Staten Island, New York City, while 42 workers were cleaning the tank. The tank had supposedly been completely drained ten months earlier, but ignition occurred, causing a plume of combusting gas to rise. Two workers near the top felt the heat and rushed to the safety of scaffolding outside, while the other 40 workers died as the concrete cap on the tank rose 20 to 30 feet (6.1 to 9.1 m) in the air and then came crashing back down, crushing them.

The incident was the worst industrial accident in Staten Island's history. It resulted in a moratorium on liquefied natural gas storage facilities in New York state.
