What device is most commonly used to extinguish peripheral fires after rescue operations?

The use of a hand line is ideal for extinguishing peripheral fires after rescue operations because it provides a direct, controlled stream of water that can be easily maneuvered by the operator. Hand lines are versatile and can be deployed quickly, allowing firefighters to effectively combat fires in various scenarios without the need for large, bulky equipment. They are suited for both offensive and defensive firefighting tactics, making them particularly useful when following up on rescue efforts, where the focus may shift to controlling and extinguishing fires to ensure the safety of both victims and responders.

In contrast, foam lines are more specialized and are typically employed in situations involving flammable liquids, while water tenders are meant for transporting large quantities of water to areas lacking a reliable water supply. Fire extinguishers have a more limited capacity and are generally intended for small, contained fires rather than larger peripheral fires that require a more sustained flow of water. Thus, the hand line is the most effective choice for the scenario presented.
