What is a key technique for controlling a fire without entering the area?

Boundary cooling is a key technique for controlling a fire without having to directly enter the affected area. This method involves applying water or other cooling agents to the areas surrounding the fire to reduce the temperature and prevent the fire from spreading. By cooling the surrounding structures, materials, and atmospheric conditions, boundary cooling can help contain the fire, make the environment safer for potential rescuers, and protect nearby assets from heat damage.

This technique is particularly important in situations where direct access to the fire is too dangerous or impractical. It allows for strategic management of a fire situation from a safe distance, effectively mitigating the threats posed by the flames and heat.

In contrast, other methods such as extinguishing with a fire blanket or direct application of foam typically require closer proximity to the fire, which can pose significant risks to the personnel involved. While evacuating individuals is crucial for ensuring safety, it does not actively control the fire itself. Boundary cooling is a more proactive technique that addresses the fire's intensity and spread without the need for firefighters to enter the immediate danger zone.
