What rescue technique should be used for a guest facing away from the lifeguard?

The rear hug technique is appropriate for rescuing a guest who is facing away from the lifeguard because it allows for an effective approach without alarming or startling the guest. This technique provides the rescuer with the ability to secure the guest from behind, ensuring that the guest is safely held without the rescuer being at risk of going underwater themselves.

In situations where the individual is not aware of the lifeguard's presence, using the rear hug can be especially important for maintaining control over the situation. The lifeguard can ensure a secure grip while simultaneously guiding the guest towards safety. This method takes advantage of the element of surprise and minimizes the chance of the guest panicking, which could lead to additional complications during the rescue.

Other rescue techniques like the front drive or two-guard rescue may not be as suitable, since they require the guest to be facing towards the lifeguard. The duck pluck method is specifically designed for different rescues, such as extracting a person submerged underwater, making it irrelevant in this context. Hence, the rear hug is the most effective technique when dealing with a guest who is positioned away from the lifeguard.
