The fire tetrahedron. The fire tetrahedron represents the addition of the chemical chain reaction to the three already present in the fire triangle.. Combustion is a chemical reaction that feeds a fire more heat and allows it to continue.
Fire is one of the four classical ... the Platonic solid he associated with fire was the tetrahedron which is formed from four triangles and contains the least volume ...
Fire tetrahedron. Hot, condensed aerosol fire-extinguishing agents act on both physical and chemical levels. They leverage four methods to extinguish fires, for they act on the four elements of what is known as the fire tetrahedron. These four means of fire extinction are: Reduction or isolation of fuel; Reduction or isolation of oxygen ...
In geometry, a tetrahedron (pl.: tetrahedra or tetrahedrons), also known as a triangular pyramid, is a polyhedron composed of four triangular faces, six straight edges, and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra. [1]
The tetrahedron is self-dual (i.e. its dual is another tetrahedron). The cube and the octahedron form a dual pair. The dodecahedron and the icosahedron form a dual pair. If a polyhedron has Schläfli symbol {p, q}, then its dual has the symbol {q, p}. Indeed, every combinatorial property of one Platonic solid can be interpreted as another ...
See also fire tetrahedron for the currently used model in firefighting. Fire wall: Building structure designed to delay horizontal spread of a fire from one area of a building to another; often regulated by fire code and required to have self-closing doors, and fireproof construction.
Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1] The surfactants used must produce foam in concentrations of ...
A fire extinguishing agent. It works by breaking the chemical chain reaction in the "fire tetrahedron". Dry hydrant A fire hydrant with a valve located at the bottom of the barrel, near the water main. The barrel of the hydrant remains dry until used.
