What are throw bags used for in water rescue?

Throw bags are specifically designed for use in water rescue situations, serving as a critical tool to provide a lifeline to a victim in need of assistance. They typically contain a length of rope that is coiled within a bag for easy deployment.

When a rescuer throws the bag to someone struggling in the water, the victim can grasp the rope, allowing the rescuer to pull them to safety. This method helps maintain a safe distance between the rescuer and the victim, which is particularly important in turbulent water conditions where there is a risk of the rescuer being pulled in.

The other options, while they each serve important roles in various emergency scenarios, do not accurately describe the primary function of throw bags in water rescue. Anchoring a boat or signaling for help would require different tools and strategies, and carrying first aid supplies typically involves specialized kits rather than throw bags. Therefore, recognizing the unique purpose of throw bags is essential for effective water rescue response.
