Using water is one common method to extinguish a fire. Water extinguishes a fire by cooling, which removes heat because of water’s ability to absorb massive amounts of heat as it converts to water vapor. Without heat, the fuel cannot keep the oxidizer from reducing the fuel in order to sustain the fire.

Where do firefighters get water for wildfires?
