What is the primary purpose of using rescue tubes for lifeguards?

The primary purpose of using rescue tubes for lifeguards is to minimize personal danger while performing a rescue. The rescue tube is an essential rescue device that provides buoyancy to both the lifeguard and the distressed swimmer, allowing the lifeguard to approach and assist the swimmer safely without putting themselves at risk of drowning.

When a lifeguard enters the water to rescue someone, their own safety is paramount, and the rescue tube acts as a flotation device. It enables the lifeguard to maintain their own stability in the water while extending it to the distressed individual. This not only secures the lifeguard but also offers the swimmer something to hold onto during the rescue, enhancing the chances of a successful outcome.

The other options do not align with the primary function of rescue tubes. Making the pool look appealing is not a function of the rescue tube; it is primarily a safety device. While rescue tubes can sometimes be used in teaching swimming lessons, their design and purpose are primarily oriented toward rescue scenarios. Additionally, holding swimming supplies is not a function associated with rescue tubes; they are specifically designed for lifesaving efforts.
