What is combustion in fire science?

Combustion in fire science is defined as a chemical reaction that occurs between a fuel and an oxidizer, typically oxygen, resulting in the production of heat and light. This process is fundamental to the understanding of fire behavior and dynamics. During combustion, the fuel is oxidized, leading to the release of energy in the form of heat, which can subsequently cause the surrounding materials to ignite and sustain the fire. The light produced can be seen as flames or glowing embers, indicating the presence of this reaction.

Understanding combustion is essential for fire prevention, firefighting strategies, and recognizing how fires spread. It highlights the critical relationship between fuel, oxygen, and heat, commonly known as the fire triangle. Without these elements, combustion cannot occur, which is vital knowledge for those in the fire service when assessing and managing fire hazards.
