A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] 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.

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[ citation needed ]

<span class="mw-page-title-main">Pipeline</span> Pumping fluids or gas through pipes

A pipeline is a system of pipes for long-distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than 2,175,000 miles (3,500,000 km) of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. The main attribute to pollution from pipelines is caused by corrosion and leakage.

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.

Texas Eastern Pipeline (TETCo) is a major natural gas pipeline which brings gas from the Gulf of Mexico coast in Texas and Louisiana up through Mississippi, Arkansas, Tennessee, Missouri, Kentucky, Illinois, Indiana, Ohio, and Pennsylvania to deliver gas in the New York City area. It is one of the largest pipeline systems in the United States. It is owned by Enbridge. Its FERC code is 17.

Enterprise Products Partners L.P. is an American midstream natural gas and crude oil pipeline company with headquarters in Houston, Texas. It acquired GulfTerra in September 2004. The company ranked No. 105 in the 2018 Fortune 500 list of the largest United States corporations by total revenue. Dan Duncan was the majority owner until his death in 2010.

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.

<span class="mw-page-title-main">Energy accidents</span>

Energy resources bring with them great social and economic promise, providing financial growth for communities and energy services for local economies. However, the infrastructure which delivers energy services can break down in an energy accident, sometimes causing considerable damage. Energy fatalities can occur, and with many systems deaths will happen often, even when the systems are working as intended.

The 2003 Etobicoke gas explosion was a disaster which occurred on April 24, 2003, after a backhoe operated by Enbridge contractor Precision Utility breached a pipeline on Bloor Street in the Etobicoke district of Toronto, Ontario. The resulting explosion destroyed a two-story mixed commercial and residential building, killing seven people and injuring another four. Enbridge and several other companies were fined for the disaster in 2011. A memorial garden was dedicated at the site of the explosion in 2008.

<span class="mw-page-title-main">2016 Portland, Oregon gas explosion</span> Gas explosion

A large natural gas explosion occurred in the Northwest District of Portland, Oregon, USA, at NW 23rd Avenue and NW Glisan Street on October 19, 2016. Nearby excavation caused a natural gas leak that triggered the explosion, which injured eight people and caused $17.2 million in property damages. The PUC determined the cause to be inadequate notification by the contractor, Loy Clark Pipeline. Thirteen buildings were damaged, including total destruction of the Alfred C.F. Burkhardt House, built in 1906 and listed on the NRHP.
