1992 Explosion In Guadalajara
A series of ten explosions took place on April 22, 1992, in the downtown district of Analco Colonia Atlas in Guadalajara city, Jalisco state, Mexico. Numerous gasoline explosions in the sewer system and fires over four hours destroyed of streets. Gante Street was the most damaged. By the accounting of Lloyd's of London, the reported number of people killed was about 252, although many estimate that the catastrophe actually caused at least 1,000 deaths. About 500 to 600 people were missing, nearly 500 were injured and 15,000 were left homeless. The estimated monetary damage ranges between $300 million and $3 billion. The affected areas can be recognized by the more modern architecture in the areas that were destroyed. Four days before the explosion, residents started complaining of a strong gas-like smell coming from the sewers which became progressively more pungent over the course of those days. They were experiencing symptoms such as stinging in their eyes and throats; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen or hydroxide. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal and results in a distinctive orange colouration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including strength, appearance and permeability to liquids and gases. Man ...

Explosions In 1992
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 ...

History Of Guadalajara, Jalisco
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Gas Explosions
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. Lis ...

East Boston Gas Surge
The East Boston gas surge was a series of fires and at least one explosion that took place early on the morning of September 23, 1983. An underground control that regulated the flow of natural gas failed, causing a surge of the fuel into the neighborhood of East Boston, Massachusetts. The sudden swell of gas rushed into businesses and residences, increasing the size of pilot lights to as much as a foot high. A number of fires started as a result and the second floor of one building in the Central Square area exploded. Between 3:15 am and 8:00 am, 9-1-1 operators received approximately 170 calls reporting fires and the smell of gas. People rushed into the streets, and McClellan Highway and the Callahan Tunnel were closed to incoming traffic with the exception of emergency vehicles. By mid-morning, the fires had been extinguished and the gas problem was fixed. The Boston Gas Company later said that a broken water main A water distribution system is a part of water supply netw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1929 Ottawa Sewer Explosion
On May 29, 1929, a series of explosions in the sewers of Ottawa, Ontario, Canada, killed one person. The first blast occurred just after noon in the Golden Triangle area, west of the canal; over the next 25 minutes, a series of explosions travelled the length of the main line of the sewer system. The explosions first moved east under the canal and then moved through Sandy Hill under Somerset Street. After passing under the Rideau River, they followed the line as it turned north through what is today Vanier, before going through New Edinburgh to the point where the sewer system emptied into the Ottawa River. The blasts were fairly small, except when manhole covers were involved. At these points, the access to oxygen fuelled towering flames that erupted through the manhole covers onto city streets. The covers themselves were blown high into the air. Most of the damage from the sewer explosions occurred where sewage lines were attached to less sturdy pipes inside houses; blasts ...

Louisville Sewer Explosions
On February 13, 1981, a series of explosions destroyed more than of sewer lines and streets in the center of Louisville in Kentucky, United States. The explosions resulted in extensive damage to property and infrastructure; there were no fatalities, but four people were injured. The blasts were caused by the ignition of hexane vapors which had been illegally discharged from a soybean processing plant owned by Ralston-Purina and located on Floyd Street. The plant had been a processing facility for cottonseed or soybeans since at least 1900. Repairs to the sewers and streets took about two years. Ralston-Purina paid $18 million to the Louisville Metropolitan Sewer District, about $9 million to about 17,000 plaintiffs in a lawsuit settled in 1984, $4 million to the city, and $2 million to affected members of the public that did not sue the company. The company admitted that it had released hexane into the sewers, but initially did not accept responsibility for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2014 Kaohsiung Gas Explosions
On 31 July 2014, a series of gas explosions occurred in the Cianjhen and Lingya districts of Kaohsiung, Taiwan, following reports of gas leaks earlier that night. Thirty-two people were killed and 321 people were injured. Event The explosions Eyewitnesses reported a smell of gas and white smoke coming out of manholes near Kaisyuan 3rd Road and Ersheng 1st Road in Cianjhen District on 31 July 2014 at 20:46, over three hours prior to the incident. The explosions occurred later at 23:57 on Yisin Road, Ersheng Road, Sanduo Road and Guanghua Road. Witnesses reported seeing fireballs soaring into the sky and flames reaching 15 stories high. The blasts ripped up roads, trapped and overturned cars and firetrucks, and caused a blackout to the electrical grid. About 6 km of road length were damaged. The explosions reportedly blew cars and motorcycles high up in the air; some vehicles and victims were found at the rooftops of buildings three or four stories high. One str ...
