The Fire Triangle is a simple model for understanding the necessary ingredients for fire. It consists of three elements: heat, fuel, and oxygen. When these three components are present in the right conditions, a fire can ignite and sustain itself. To extinguish a fire, one of these elements must be removed. For example, using water can cool the heat, while smothering a fire can cut off its oxygen supply. Understanding the Fire Triangle is essential for fire safety and prevention, as it helps identify how to control or eliminate fire hazards effectively.
