A primary concern when conducting a structural fire attack is understanding fire behavior. This includes recognizing how fire spreads, the stages of fire development, and the factors that influence fire dynamics such as fuel availability, ventilation, and heat release rates. By having a solid grasp of fire behavior, firefighters can make informed decisions about tactics, such as when and how to attack the fire, how to control and contain it effectively, and how to ensure their own safety and the safety of any occupants who may be inside.

For instance, awareness of heat and smoke movement can help firefighters anticipate potential flashover situations and identify safe routes for entering or exiting a structure. Additionally, understanding how fire might behave in different environments or architectural designs allows firefighters to adjust their techniques accordingly. This knowledge is essential for executing a successful and safe fire attack, making fire behavior a critical focal point during operations.
