Electrical burns

The gravitational field affects olfaction as it does vision, audition, or vestibular function. It could impair detection of dangerous fumes or burning electrical equipment in airplanes or space vehicles. Astronauts also report altered perception of food flavors under weightless conditions. Men and women tested with four scratch-and-sniff odor samples of the University of Pennsylvania Smell Identification Test identified odors more poorly when in an upside-down position (Mester eta/., 1988). 

Coal burning electrical power station. Large central power stations (about 1000 MW electrical) using fluidized bed combustors may be built some day (see Fig. P1.2). These giants would be fed 240 tons of coal/hr (90% C, 10%... 

Phase 1 began in 1995 and affects 263 units at 110 mostly coal-burning electric utility plants located in 21 eastern and midwestern states. An additional 182 units joined Phase I of the program as substitution or compensating units, bringing the total of Phase 1 affected units to 445. Emissions data indicate that 1995 SO emissions at these units nationwide were reduced by almost 40% below their required level. 

Sulfur dioxide in the effluent gases from coal-burning electric power plants is one of the principal causes of acid rain. One method for reducing S02 emissions involves partial reduction of S02 to H2S, followed by catalytic conversion of the H2S and the remaining S02 to elemental sulfur ...

Combu.stion of coal accounts for about 65% of the SO2 released annually in the United States, and combustion of oil accounts for another 20%. TThe majority of this amount is from coal-burning electrical power plants, which generate about 50% of our electricity. The extent to which SO2 emissions are a problem when coal is burned depends on the amount of sulfur in the coal. Because of concern about SO2 pollution, low-sulfur coal is in greater demand and is thus more expensive. Much of the coal from east of the Mississippi is relatively high in sulfur content, up to 6% by mass. Much of the coal from the western states has a lower sulfur content, but also a lower heat content per unit mass, so the difference in sulfur content per unit of heat produced is not as large as is often assumed. 

Oil-burning electric generating plants can also produce comparable amounts of SOg because some fuel oils can contain up to 4% sulfur. The sulfur in the oil is in the form of compounds in which sulfur atoms are bound to carbon and hydrogen atoms. Gasoline contains relatively low concentrations of sulfur-containing compounds. Even so, the EPA has mandated that the maximum concentration of sulfur-containing compounds be reduced from 120 ppm in 2004 to 90 ppm in 2005 and to 30 ppm by 2006. Further mandated reductions may be expected.

The scope of this study is to illustrate how a maintenance and reinvestment strategy can be designed in order to manage the risks and costs associated with these assets. A strategy is considered to be a set of rules about what to do with different types of assets, e.g. whether to maintain or replace them. The case is built upon previous research reported in (Nordgard, 2008 Nordgfcd Sand 2008) and has as focus on personnel injury caused by malfunction of manually operated switch with a burning electric arc as a result.

It has been said that properly used electricity is not dangerous but out of control it can cause harm, if it passes through a human body, by producing electric shock and/or burns. Electricity s heating effect can also cause fire but we will now deal with the electric shock phenomenon. 

Smoke is produced by burning hydrocarbons and solids in considerable quantities, (particularly under conditions of incomplete combustion). It is also produced in large quantities by burning electrical and electronic equipment. Smoke consists of finely divided particulate matter and suspended liquid droplets (aerosols) and can contain toxic byproducts of combustion. Smoke creates a serious hazard to personnel due to its physiological effects and the reduction of visibility (most of the deaths on the Piper Alpha platform were of men in their living quarters who were overcome by smoke).
