The materials involved in the fire are crucial in determining fire behavior because they directly influence how a fire ignites, spreads, and behaves. Different materials have varying ignition temperatures, burn rates, and combustion characteristics. For example, flammable materials such as gasoline or propane ignite more readily and burn faster than non-flammable materials like concrete.

The chemical composition of the materials also dictates the amount of heat produced, the duration of the fire, and the smoke produced, which can affect visibility and breathing conditions. Understanding the types of materials present allows firefighters to anticipate the fire's behavior and implement appropriate firefighting tactics.

Environmental factors like weather conditions and humidity can certainly impact fire behavior as well; however, without understanding the materials burning, it would be challenging to effectively manage the fire. Thus, recognizing the fire load and its characteristics is key to successful firefighting strategies.
