  2. Fire - Wikipedia

    en.wikipedia.org/wiki/Fire

    Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [ 1 ] [ a ] At a certain point in the combustion reaction, called the ignition point, flames are produced.

  3. Fire triangle - Wikipedia

    en.wikipedia.org/wiki/Fire_triangle

    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. Once a fire has started, the resulting exothermic chain reaction sustains the fire and allows it to continue until or unless at ...

  4. Colored fire - Wikipedia

    en.wikipedia.org/wiki/Colored_fire

    Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam.

  5. Fire retardant - Wikipedia

    en.wikipedia.org/wiki/Fire_retardant

    Fire retardant dispersed aerially onto brush adjoining a firebreak to contain the Tumbleweed Fire in California, in July 2021. A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their ...

  6. Flame - Wikipedia

    en.wikipedia.org/wiki/Flame

    Flames of charcoal. A flame (from Latin flamma) is the visible, gaseous part of a fire.It is caused by a highly exothermic chemical reaction made in a thin zone. [1] When flames are hot enough to have ionized gaseous components of sufficient density, they are then considered plasma.

    The red color of the fire retardant is caused by the chemical component iron oxide, commonly known as rust. ... How does fire retardant work? The long-term fire retardant, often used to steer ...

  8. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

    A non-combustible material [17] is a substance that does not ignite, burn, support combustion, or release flammable vapors when subject to fire or heat, in the form in which it is used and under conditions anticipated. Any solid substance complying with either of two sets of passing criteria listed in Section 8 of ASTM E 136 when the substance ...
