PEPCON Disaster
On May 4, 1988, a fire followed by several explosions occurred at the Pacific Engineering and Production Company of Nevada (PEPCON) chemical plant in Henderson, Nevada. The disaster caused two fatalities, 372 injuries, and an estimated $100 million of damage. A large portion of the Las Vegas Valley within a radius of the plant was affected, and several agencies activated disaster plans. Background The PEPCON plant, located in Henderson, Nevada, from Las Vegas, was one of only two American producers of ammonium perchlorate ("AP"), an oxidizer used in solid propellant rocket boosters, including the Space Shuttle, military weapons (SLBMs launched from nuclear submarines), and non-weaponized rocket programs (Atlas, Patriot, etc.). The other producer, Kerr-McGee, was located less than away from the PEPCON facility, within the area that suffered some blast damage. In addition to ammonium perchlorate, the plant produced other perchlorate chemicals including sodium perchlorate. The fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

TNT Equivalent
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The is a unit of energy defined by that convention to be , which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT. In other words, for each gram of TNT exploded, (or 4184 joules) of energy is released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. Kiloton and megaton The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules (). The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules (). The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various nuclear weapon control treaties, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flying Glass
Flying glass refers to pieces of broken glass (typically from a window) which become sharp missiles projected by the force which broke the glass, along with any strain energy due to tempering. They often cause cut-type injuries. Flying glass resulting from an explosion poses a significant risk in the event; up to 85% of injuries from an explosion are due to flying glass. Severity of injury from flying glass depends on the peak overpressure of the blast. Potential for injury has been derived from both experiments and theoretical modeling of blast effects. Among the important features in models of flying glass are breaking pressure, velocity and distribution of flying fragments, fragment shape, and the distance traveled until impact. Mitigation strategies, such as the use of window glazing or laminated glass Laminated glass (LG) is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by a thin polymer interlayer, typically of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
