What device is most commonly used to extinguish a peripheral fire after rescue operations are complete?

The hand line is the most commonly used device to extinguish a peripheral fire after rescue operations are complete due to its versatility and effectiveness in controlling smaller fires. Hand lines are flexible hoses that firefighters can maneuver easily. They can deliver water or firefighting agents where they are needed, allowing for precise targeting of the fire.

In the context of ARFF operations, once rescue efforts have concluded, personnel often need to quickly move to extinguish remaining fires to prevent any reignition or further escalation of the situation. Hand lines enable firefighters to adjust the flow and reach of the water stream effectively, ensuring that they can manage the fire safely and efficiently.

While other devices like water cannons can deliver large volumes of water from a distance, they tend to be more suited for defensive operations and may not allow for the precision required in urban firefighting or in situations where nearby aircraft or structures are involved. Foam generators are primarily used when dealing with flammable liquid fires and may not be suitable for all types of peripheral fires. Fire blankets, while useful for certain applications, are limited in their capability to extinguish larger fires. Overall, the hand line remains a fundamental tool for firefighters to effectively manage and extinguish various fire scenarios.
