Which three components are essential to start a fire?

The three essential components required to start a fire are oxygen, heat, and fuel. This is commonly known as the fire triangle.

Oxygen is crucial because it supports the chemical reactions that occur during combustion. Without a sufficient amount of oxygen, a fire cannot sustain itself. Heat is needed to raise the temperature of the materials involved to their ignition point, initiating the combustion reaction. Finally, fuel—the material that burns—provides the substance that undergoes the chemical reaction when ignited.

Understanding this concept is vital, especially in safety and survival situations, as removing any one of these components can effectively extinguish a fire. Other options may reference items that can help ignite or maintain a fire, but they do not address the fundamental components necessary for combustion.
