What does securing a safety line during a swiftwater rescue help ensure?

Securing a safety line during a swiftwater rescue is vital because it provides a reliable method for retrieval if the situation requires it. This line acts as a lifeline for the rescuer and the victim, creating a connection that can be crucial in preventing further hazards or in securing the rescuer's position amidst the swift currents. If the rescuer is unable to reach the victim directly or if the victim begins to drift away, the safety line provides a means to pull them back to safety or to assist them in gaining stability in the turbulent water.

Having a safety line allows for a controlled and measured approach to the rescue, ensuring that both the rescuer and the victim can be managed effectively. It also enables coordination, where other team members can assist without having to enter the water themselves, thereby enhancing overall safety during the operation.
