What are the three components necessary for fire to occur?

The three components necessary for fire to occur are oxygen, heat, and fuel. This concept is often referred to as the "fire triangle."

Oxygen is essential because it supports the chemical process of combustion. Without adequate oxygen, fire cannot ignite or sustain itself. Heat is the energy source that raises the temperature of the material to its ignition point, enabling the combustion process to take place. Finally, fuel is any combustible material that can burn, providing the substance that is consumed during the reaction.

Understanding these three elements is crucial in fire safety because eliminating any one of them will extinguish the fire, which is a fundamental principle in fire prevention and firefighting strategies.
