Fire, a form of combustion, is the most spectacular chemical phenomenon. Linguistically, the word fire refers to the combination of the brilliant glow and large amount of heat released during a rapid, self-sustaining burning of combustible fuel. Technically, fire is not a state of matter; it is an exothermic oxidation process by which heat and light energy are given out. Fire starts when a fuel with adequate supply of oxygen or other oxidizer is subjected to enough heat, and it is sustained by the further release of heat energy ...

Controlling fire for the purposes of providing heat and light was one of humankind's first great achievements. The ability of fire to generate heat and light made possible migration to colder climates and enabled people to cook food — a decisive step in the perennial fight against disease. Smoke signals were an early use of fire for communication, and fire soon enabled advancements in metallurgy such as smelting and forging. Archaeology indicates that ancestors of modern humans such as Homo erectus seem to have been using controlled fire as early as some 790,000 years ago. The Cradle of Humankind site has evidence ...

The fire started when pyrotechnics set off by Great White, the rock band playing that night, lit flammable soundproofing foam behind the stage. The flames were first thought to be part of the act; only as the fire reached the ceiling and smoke began to billow did people realize it was uncontrolled. The ensuing stampede in the inferno led to the numerous deaths among the patrons, who numbered somewhat more than 404, the ...

The late winter and early spring of 1966 had been wet over southeastern Tasmania, giving a large amount of growth by November. However, in November, Tasmania began its driest eight-month period since 1885, and by the end of January 1967 the dryness had dried off the luxuriant growth provided by the early spring rains in the area. Though January was a cool month, hot weather began early in February, so that in the days leading up to 7 February 1967, several bushfires were burning uncontrolled in the areas concerned. Some of these fires had be ...

Controlled detonation may be accomplished by use of either an electrical or nonelectrical firing system. When mines are employed in the controlled role, they are treated the same as individual weapons and are ...

Fire has supplied much of the energy which has helped humans since ancient times, from the wood fires which served many prehistoric purposes to the oil, gas and coal power stations of today which supplies the vast majority of the world's electricity (nearly 80%1). Mexico is typical with thermal energy providing 76% of all energy2. The burning of wood is often the first association to the word "fire". It is common in a developing country for wood to be the primary energy source as well. For instance, in Africa, 65 ...

See also: Fire ecology A flame is a self-sustaining oxidizing chemical reaction producing energy and ionized gas (plasma). It consists of reacting gases emitting visible and infrared light, the frequency spectrum of which is dependent on the chemical composition of the burning elements and intermediate reaction products. In many cases such as burning organic matter like wood or incomplete combustion of gas, incandescent solid particles (soot) produce the familiar red-orange 'fire' color light. This light has a continuous spectr ...
