Gas Explosion
A gas explosion is an explosion resulting from mixing a gas, typically from a gas leak, with air in the presence of an ignition source. 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 (American English)/petrol (British English) or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition. Lower and upper explosive limits Whether a mixture of air and gas is combustible depends on the air-to-fuel ratio. For each fuel, ignition occurs only within a certain range of concentration, known as the upper and lower flammability limits. For example, for methane and gasoline vapor, this range is 5-15% and 1.4-7.6% gas to air, respectively. An explosion can only occur when fuel concentration is within these limits. L ...

Explosion
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large influx of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in events su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fairgrounds Coliseum
The Indiana Farmers Coliseum (originally Indiana State Fairgrounds Coliseum and formerly Pepsi Coliseum and Fairgrounds Coliseum) is a 6,500-seat indoor multi-use arena, located on the Indiana State Fairgrounds in Indianapolis. The Indiana Farmers Coliseum is home to both the Indy Fuel of the ECHL and the IUPUI Jaguars of the NCAA. Originally opened in 1939 as part of President Franklin D. Roosevelt's Works Progress Administration (part of the New Deal), the Coliseum has hosted numerous historical events, including the only performances ever held in Indiana by The Beatles, in 1964. After Market Square Arena opened in 1974, the coliseum continued on as an alternate venue to the larger arena for events requiring less seating or overall space. This continues today after the Gainbridge Fieldhouse opened in 1999, and the subsequent demolition of Market Square Arena in 2001. On October 26, 2012, the Coliseum held a "Lights Out" ceremony and closed for renovations. On April 24, 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1963 Indiana State Fairgrounds Coliseum Gas Explosion
A gas explosion at the Indiana State Fairgrounds Coliseum in Indianapolis on October 31, 1963, killed up to 81 people and injured about 400 others. It was one of the worst disasters in the history of both the city and the U.S. state of Indiana. On that night, over 4,000 people were in the arena to watch a Holiday on Ice performance. While this was happening, liquefied petroleum gas was leaking from a tank that was stored with several others in a supply room underneath a part of the grandstands. Shortly after 11 p.m. ET, the gas came into contact with an electrical heating element from the concessions area, causing a major explosion that killed many seated above the room and caused significant damage to the stands. After the initial blast, while people were evacuating, a second blast caused by the remaining, unexploded tanks caused further destruction. Firefighters and other emergency responders were at the site within minutes and survivors were transported via ambulance to ...

New London School Explosion
The New London School explosion occurred on March 18, 1937, when a natural gas leak caused an explosion and destroyed the London School in New London, Texas, United States. The disaster killed more than 300 students and teachers. , the event is the third-deadliest disaster in the history of Texas, after the 1900 Galveston hurricane and the 1947 Texas City disaster. Background of New London School In the mid-1930s, despite the ongoing economic turmoil of the Great Depression, the school district in New London, Texas (formerly known as London) was one of the richest in the United States. The 1930 discovery of oil in Rusk County had boosted the local economy, and education spending grew with it. The city's taxable value in 1937 had grown to $20 million, with additional revenue seen from fifteen oil wells on district property. The London School, a large structure of steel and concrete, was constructed in 1932 at a cost of $1 million (roughly $ today). Its football team, the Lo ...
