Fire behavior is the study of how fires start, spread, and the factors that influence their intensity and direction. Understanding fire behavior is crucial for developing effective fire suppression systems. These systems are designed to control and extinguish fires by targeting one or more elements of the fire triangle: fuel, oxygen, and heat. Common suppression methods include cooling the fire with water, smothering it by cutting off the oxygen supply, or removing the fuel source. The choice of fire suppression system depends on the type of fire, the environment, and the specific hazards involved.
