What is the function of a rescue board?

The function of a rescue board is to provide flotation and stability during a rescue, allowing for effective transportation of a struggling swimmer. This specialized equipment is designed to support both the lifeguard and the individual in distress, ensuring that the rescuer can maintain balance and maneuver effectively in the water. The board helps to keep the victim afloat while enabling the lifeguard to control the situation and transport the swimmer safely back to shore or a safe location. This function is critical during rescues, especially in challenging water conditions where both stability and buoyancy are essential for a successful outcome.

Other options, such as monitoring water temperature or keeping track of rescues, do not pertain to the practical use of a rescue board in emergency situations. Furthermore, while the board is primarily a rescue tool for lifeguards, it's not exclusive to them; it is specifically designed for rescuing swimmers in distress, rather than being a general flotation device.
