Xcel Energy Cabin Creek Fire
The Xcel Energy Cabin Creek Fire occurred on October 2, 2007, at Xcel Energy’s pumped storage hydroelectric plant near Georgetown, Colorado, a small town forty-five miles west of Denver. The accident killed five workers and injured three. The incident is thought to be the result of botched work by a contractor (RPI Coating) and Xcel Energy's willingness to cut costs at the expense of safety. The plant The plant, the Cabin Creek Generating station, is a pumped storage hydroelectric generator that opened in 1967. It is located about 6 miles from Georgetown, accessed by the high mountain road of Guanella Pass. It sits at an elevation of greater than 10,000 feet above sea level. The power plant runs two generators that, when running at top performance, can produce a total 324 megawatts of electrical power. The plant is powered by water pressure from the water released from a storage reservoir.http://www.xcelenergy.com/Company/Operations/Cabin_Creek_Generating_Station Incident ...

In over 98% of locations in Argentina, Panama, Belize, Anguilla, Costa Rica, Ecuador, Jordan, Ethiopia, Liberia, Saudi Arabia, Philippines, Uruguay, United States, Palau, Mexico, Tonga and Canada, dialing "9-1-1" from any telephone will link the caller to an emergency dispatch office—called a Public Safety Answering Point (PSAP) by the telecommunications industry—which can send emergency responders to the caller's location in an emergency. In approximately 96 percent of the United States, the enhanced 9-1-1 system automatically pairs caller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2007 Fires In The United States
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube (algebra), cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as Symbolism of the Number 7, highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the Brahmi numerals, beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit m ...

Fires In Colorado
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and property, atmospheric pollution, and water contamination. If fire re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fifth Amendment To The United States Constitution
The Fifth Amendment (Amendment V) to the United States Constitution addresses criminal procedure and other aspects of the Constitution. It was ratified, along with nine other articles, in 1791 as part of the Bill of Rights. The Fifth Amendment applies to every level of the government, including the federal, state, and local levels, in regard to a US citizen or resident of the US. The Supreme Court furthered the protections of this amendment through the Due Process Clause of the Fourteenth Amendment. One provision of the Fifth Amendment requires that felonies be tried only upon indictment by a grand jury. Another provision, the Double Jeopardy Clause, provides the right of defendants to be tried only once in federal court for the same offense. The self-incrimination clause provides various protections against self-incrimination, including the right of an individual not to serve as a witness in a criminal case in which they are the defendant. "Pleading the Fifth" is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US Chemical Safety And Hazard Investigation Board
The U.S. Chemical Safety and Hazard Investigation Board (USCSB), generally referred to as the Chemical Safety Board or CSB, is an independent U.S. federal agency charged with investigating industrial chemical accidents. Headquartered in Washington, D.C., the agency's board members are appointed by the president and confirmed by the United States Senate. The CSB conducts root cause investigations of chemical accidents at fixed industrial facilities. History The U.S. Chemical Safety Board is authorized by the Clean Air Act Amendments of 1990 and became operational in January 1998. The Senate legislative history states: "The principal role of the new chemical safety board is to investigate accidents to determine the conditions and circumstances which led up to the event and to identify the cause or causes so that similar events might be prevented." Congress gave the CSB a unique statutory mission and provided in law that no other agency or executive branch official may direct the ...

Henderson Mine
The Henderson molybdenum mine is a large underground molybdenum mine west of the town of Empire in Clear Creek County, Colorado, USA. The Henderson mine, which has produced molybdenum since 1976, is owned by Freeport-McMoRan. The Henderson mine is North America's largest producer of primary molybdenum. 2007 production was 40 million pounds of molybdenum, with a value of $1.1 billion. History The Henderson mine is near the Urad mine, which produced molybdenum from 1914 to the 1960s, before exhausting its orebody. Owner Climax Molybdenum Co. recognized the potential for deeper orebodies in the area, and discovered the Henderson deposit in 1964. The mine was named after mining engineer Robert Henderson. Production began in 1976; on Jan. 4, 2010, workers mined the billionth pound of molybdenum. In 2006, remaining ore reserves were estimated to be 500 million pounds of recoverable molybdenum. It was considered by the National Science Foundation as one of the two final candidates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mine Rescue
Mine rescue or mines rescue is the specialised job of rescuing miners and others who have become trapped or injured in underground mines because of mining accidents, roof falls or floods and disasters such as explosions. Background Mining laws in developed countries require trained, equipped mine rescue personnel to be available at all mining operations at surface and underground mining operations. Mine rescue teams must know the procedures used to rescue miners trapped by various hazards, including fire, explosions, cave-ins, toxic gas, smoke inhalation, and water entering the mine. Most mine rescue teams are composed of miners who know the mine and are familiar with the mining machinery they may encounter during the rescue, the layout of workings and geological conditions and working practices. Local and state governments may have teams on-call ready to respond to mine accidents. Rescuers and equipment The first mines rescuers were the colliery managers and volunteer coll ...

Methyl Ethyl Ketone
Butanone, also known as methyl ethyl ketone (MEK), is an organic compound with the formula CH3C(O)CH2CH3. This colourless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts.Wilhelm Neier, Guenter Strehlke "2-Butanone" in Ullmann's Encyclopedia of Industrial Chemistry, Wiley-VCH, Weinheim, 2002. It is partially soluble in water, and is commonly used as an industrial solvent. It is an isomer of another solvent, tetrahydrofuran. Production Butanone may be produced by oxidation of 2-butanol. The dehydrogenation of 2-butanol is catalysed by copper, zinc, or bronze: :CH3CH(OH)CH2CH3 → CH3C(O)CH2CH3 + H2 This is used to produce approximately 700 million kilograms yearly. Other syntheses that have been examined but not implemented include Wacker oxidation of 2-butene and oxidation of isobutylbenzene, which is analogous to the industrial production of acetone. The cumene process ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Confined Space
A confined space is a space with limited entry and egress and not suitable for human inhabitants. An example is the interior of a storage tank, occasionally entered by maintenance workers but not intended for human occupancy. Hazards in a confined space often include harmful dust or gases, asphyxiation, submersion in liquids or free-flowing granular solids (for example, grain bins), electrocution, or entrapment.BP International Ltd. ''Confined Space Entry'', Institution of Chemical Engineers 2005 pp. 1-14 Confined space accidents are of particular concern in occupational safety and health due to the hazards that they pose to the victim and subsequently to a rescue team. Confined space training outlines the skills and protocols for safe entry to confined spaces, and includes precautions such as locking and tagging out connecting piping, testing of breathable air quality, forced ventilation, observation of workers in the space, and a predetermined rescue plan with appropriate safet ...
