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] Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point.

Learn how fires start, learn about the fire triangle, how fires spread, and effective strategies to protect against fire hazards.

Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material.

Fire is a chemical reaction that gives off light and heat. Fire happens when a material rapidly oxidizes, or loses electrons, and releases a great amount of energy. Flames are only the portion of the fire that gives off visible light.

It provides a public resource of information to best prepare and manage wildfire season. Developed in a joint partnership between the EPA and USFS.

2024年7月18日 · Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Ordinarily, flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. In the usual combustion reaction, a carbon-based fuel burns in air (oxygen).
