The following outline is provided as an overview of and topical guide to fire:

Fire is the rapid oxidation of a fuel in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point. Flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. If hot enough, the gases may become ionized to produce plasma. The color and intensity of the flame depend on the type of fuel and composition of the surrounding gases.

Fire can be described as all of the following:

• a chemical reaction –
  • a form of oxidation –
  • a type of combustion –
• an exothermic process –
• a natural phenomenon –
• a hazard to life and property –
• a source of energy –
• a cause of emergency incidents –
• an environmental factor –
