What must candidates demonstrate knowledge of regarding fire behavior?

Understanding the combustion process, which includes the fire triangle and fire tetrahedron, is essential for fire behavior. The fire triangle consists of three components: heat, fuel, and oxygen, all of which are necessary for combustion to occur. When any of these elements are removed, fire will be extinguished. The fire tetrahedron expands on this concept by adding a fourth element: the chemical reaction that occurs during combustion. This knowledge equips candidates with the ability to comprehend how fires develop, spread, and can be controlled or extinguished.

This foundation is crucial for effectively combating fires, as it enables firefighters to anticipate fire behavior in various situations and environments. Knowing how different materials react when heated, the conditions that lead to flashover, and how to manipulate the fire triangle or tetrahedron through tactics such as cooling or smothering makes firefighters more effective in their roles.

In contrast, while the role of fire alarms in response is important for safety and alerting, it does not directly relate to understanding fire behavior. The history of firefighting techniques, although interesting and informative, does not provide the practical, scientific knowledge necessary for active firefighting. Lastly, while the importance of ventilation is crucial in firefighting strategies, it is a specific tactic that stems from the
