Firefighting techniques involve various methods to control and extinguish fires. One common technique is the use of water, which cools the flames and reduces heat. Firefighters may also use foam to smother the fire, cutting off its oxygen supply. Another technique is creating firebreaks, which are gaps in vegetation that prevent the fire from spreading. Firefighters may also employ controlled burns to eliminate fuel in advance of a wildfire. Each technique is chosen based on the type of fire and the environment, ensuring effective and safe firefighting efforts.
