What is the primary purpose of a rescue bag?

The primary purpose of a rescue bag is to provide tools and equipment specifically designed for rescues. These bags typically contain items such as flotation devices, rescue tubes, ropes, and other necessary gear that aid lifeguards in performing effective and safe rescues in water emergencies. Having access to the right equipment is crucial in ensuring that lifeguards can respond promptly and effectively to various situations, including assisting struggling swimmers or managing rescue operations.

In contrast, while first aid supplies are indeed important for responding to emergencies, they are not the primary focus of a rescue bag. The intention behind a rescue bag is to streamline the rescuer's ability to perform rescues rather than focusing solely on medical supplies. Other options, like storing personal items for lifeguards or assisting with training, do not align with the specific, immediate needs of conducting rescues in an aquatic environment. Therefore, the correct answer highlights the essential role of the rescue bag in enabling lifeguards to carry out their primary responsibilities safely and efficiently.
