The Fire Triangle is a fundamental concept in fire safety, illustrating the three essential elements required for a fire to start and sustain itself: fuel, heat, and oxygen. Fuel can be any combustible material, such as wood, paper, or flammable liquids. Heat provides the energy to ignite the fuel, while oxygen acts as the oxidizing agent, allowing the combustion process to continue. By removing or interrupting any one of these elements, the fire can be extinguished. This understanding of the Fire Triangle is crucial for effective fire prevention and control, as it highlights the importance of eliminating or controlling these elements to prevent fires from starting or spreading.
