What is the primary objective of a defensive fire attack?

The primary objective of a defensive fire attack is to prevent fire spread. This approach is taken when a fire presents an overwhelming threat to life or property, and where an offensive attack might be too risky or impractical. By preventing the fire from spreading to adjacent structures or areas, firefighters can protect the safety of occupants and minimize damage.

In a defensive strategy, teams may focus on establishing barriers to contain the flames and using water streams to cool surrounding materials and create safe zones. This allows for control over the situation without directly attacking the fire itself. The aim is to control the fire's impact and facilitate a safe environment for rescue operations or eventual extinguishment when the situation allows.

The other choices, while relevant in various fire situations, do not encapsulate the primary goal of a defensive attack. Quick extinguishment is often more aligned with offensive strategies. Preventing backdraft focuses on a specific fire phenomenon during interior operations, and containment of smoke, although important, serves as a supportive objective rather than the core aim of a defensive strategy.
