Willow Island Disaster
The Willow Island disaster was the collapse of a cooling tower under construction at the Pleasants Power Station at Willow Island, West Virginia, on April 27, 1978. 51 construction workers were killed. It is thought to be the deadliest construction accident in U.S. history. Background During the 1970s, many coal-powered power plants were being built in the valley along the Ohio River. The Allegheny Power System was building another, larger plant at Willow Island, which would have two electric generators with a total capacity of 1,300 megawatts. This was in addition to the two smaller units that were already installed there. By April 1978, one natural draft cooling tower had been built, and a second was under construction. One of the contractors, New Jersey-based Research-Cottrell, was well known for constructing such towers around the country. The usual method of scaffold construction has the base of the scaffold built on the ground, with the top being built higher to ke ...

Occupational Safety And Health Administration
The Occupational Safety and Health Administration'' (OSHA ) is a large regulatory agency of the United States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. Congress established the agency under the Occupational Safety and Health Act OSH Act, which President Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance". The agency is also charged with enforcing a variety of whistleblower statutes and regulations. OSHA's workplace safety inspections have been shown to reduce injury rates and injury costs without adverse effects on employment, sales, credit ratings, or firm survival. History The Bureau of Labor Standards of the Department of Labor has worked on some work safety issues since its creation in 1922. Economic boom and associated la ...

Ferrybridge Power Stations
The Ferrybridge power stations were a series of three coal-fired power stations on the River Aire near Ferrybridge in West Yorkshire, England, in operation from 1927 to 2016 on a site next to the junction of the M62 and A1(M) motorways. The first station, Ferrybridge A, was constructed in the mid-1920s and closed in 1976. Ferrybridge B was brought into operation in the 1950s and closed in the early 1990s. In 1966, Ferrybridge C power station was opened with a generating capacity of 2 GW from four 500 MW sets; constructed by the Central Electricity Generating Board (CEGB); on privatisation in 1989 ownership was passed to Powergen, then to Edison Mission Energy (1999), then to AEP Energy Services (American Electric Power) (2001) and to SSE plc (2004). Ferrybridge C closed in March 2016. Two of the four units were fitted with flue-gas desulphurisation (FGD) plant in 2009. In 2013 SSE indicated that the power station would not comply with the Industrial Emissions Di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vermont Yankee Nuclear Power Plant
Vermont Yankee was an electricity generating nuclear power plant, located in the town of Vernon, Vermont, in the northeastern United States. It generated 620 megawatts (MWe) of electricity at full power. The plant was a boiling water reactor (BWR), designed by General Electric. It operated from 1972 until December 29, 2014, when its owner Entergy shut down the plant. In 2008, the plant provided 71.8% of all electricity generated within Vermont, amounting to 35% of Vermont's electricity consumption. The plant is on the Connecticut River, upstream of the Vernon, Vermont Hydroelectric Dam and used the reservoir pool for its cooling water. In March 2012, the plant's initial 40-year operating license was scheduled to expire; in March 2011, the Nuclear Regulatory Commission (NRC) extended its license for another 20 years. Vermont Yankee's continued operations were complicated by the Vermont state legislature's enactment of a law providing the state legislature authority to deter ...

Grand Jury
A grand jury is a jury—a group of citizens—empowered by law to conduct legal proceedings, investigate potential criminal conduct, and determine whether criminal charges should be brought. A grand jury may subpoena physical evidence or a person to testify. A grand jury is separate from the courts, which do not preside over its functioning. Originating in England during the Middle Ages, grand juries are only retained in two countries, the United States and Liberia. Other common law jurisdictions formerly employed them, and most others now employ a different procedure that does not involve a jury: a preliminary hearing. Grand juries perform both accusatory and investigatory functions. The investigatory functions of grand juries include obtaining and reviewing documents and other evidence, and hearing sworn testimonies of witnesses who appear before it; the accusatory function determines whether there is probable cause to believe that one or more persons committed a particul ...

Bolted Joint
A bolted joint is one of the most common elements in construction and machine design. It consists of a male threaded fastener (e. g., a bolt) that captures and joins other parts, secured with a matching female screw thread. There are two main types of bolted joint designs: tension joints and shear joints. Joint types In a tension joint, the bolt and clamped components of the joint are designed to transfer an applied tension load through the joint by way of the clamped components by the design of a proper balance of joint and bolt stiffness. The joint should be designed such that the clamp load is never overcome by the external tension forces acting to separate the joint. If the external tension forces overcome the clamp load (bolt preload) the clamped joint components will separate, allowing relative motion of the components. The second type of bolted joint transfers the applied load in shear of the bolt shank and relies on the shear strength of the bolt. Tension loads on ...

Safety
Safety is the state of being "safe", the condition of being protected from harm or other danger. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk. Meanings There are two slightly different meanings of ''safety''. For example, ''home safety'' may indicate a building's ability to protect against external harm events (such as weather, home invasion, etc.), or may indicate that its internal installations (such as appliances, stairs, etc.) are safe (not dangerous or harmful) for its inhabitants. Discussions of safety often include mention of related terms. Security is such a term. With time the definitions between these two have often become interchanged, equated, and frequently appear juxtaposed in the same sentence. Readers unfortunately are left to conclude whether they comprise a redundancy. This confuses the uniqueness that should be reserved for each by itself. When seen as unique, as we intend here, each term will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
