Which strategy focuses on reducing fire extension before bringing it under control?

The strategy that focuses on reducing fire extension before bringing it under control is the defensive attack. In a defensive attack, firefighting efforts are directed toward containing the fire and preventing it from spreading further, rather than engaging in direct suppression of the flames. This approach is particularly important in situations where the fire may pose a significant risk to life or where resources are limited.

By concentrating on reducing fire extension, firefighters can establish a perimeter and protect exposures, which helps to minimize property loss and potentially safeguard individuals in the vicinity. The defensive strategy allows for better assessment of the situation, the safe deployment of resources, and effective long-term planning to mitigate risks. This proactive containment helps to stabilize the incident before launching additional efforts to control or extinguish the fire.
