A huge cylindrical gasometer, the largest in the world at that time at 5 million cubic feet (140,000 m3), developed a leak, and repairmen were sent to fix it. The exact cause of the explosion is not known, but some of those repairing the leak were using acetylene torches. [2]
There was a loud explosion, and three gasometers at the site exploded. [2] A "dense mass of dust and smoke" rose from the ruins before igniting into a ball of fire reported as 100 feet in diameter, which rose further before burning out at a height of 1000 feet. [1] Most buildings within a radius of half a mile were damaged, with windows being broken a mile away, [1] causing upwards of $4 million worth of damage. [2]
It was reported that the explosion "caused lofty downtown skyscrapers to tremble and sway as if hit by an earthquake". [2] 28 people were killed and hundreds were injured. [1]
A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane. In industrial explosions many other gases, like hydrogen, as well as evaporated (gaseous) gasoline or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition, or use of alternative energy.
There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.
The Waverly, Tennessee tank car explosion killed 16 people and injured 43 others on February 24, 1978, in Waverly, Tennessee. Following a train derailment a two days earlier, a cleanup crew had been sent into the area. At approximately 2:58 in the afternoon, a tank car containing 30,161 US gallons of liquefied petroleum gas (LPG) exploded after an action taken during the cleanup related to the derailment.
The Falk Corporation explosion refers to a large and fatal propane gas explosion at a Falk Corporation building in the industrial Menomonee River Valley neighborhood of Milwaukee, Wisconsin on December 6, 2006. Three people were killed and forty-seven others injured. Cars were reportedly flipped through the air and debris scattered over several blocks. An investigation of the cause of the disaster uncovered leaks in a pipe running below the building, which supplied propane to the heating system for the complex. Several parties involved in the explosion have launched legal action in connection to the accident.
On the evening of December 27, 1983, firefighters in Buffalo, New York responded to a call regarding a propane gas leak. Shortly after their arrival, the propane ignited, leveling a warehouse and causing a wide swath of damage. Five firefighters and two civilians were killed in the blast, and left dozens more injured. The event remains the largest single day loss of life for the Buffalo Fire Department.
