What type of rescue should you perform if a guest is beyond arm's reach while submerged?

The appropriate type of rescue for a guest who is beyond arm's reach while submerged is a deep-water rescue. This method is specifically designed for situations where lifeguards need to reach individuals who are not accessible from the surface due to their distance or depth underwater. In a deep-water rescue, the lifeguard has the training and protocols to safely reach and assist the submerged individual, using techniques that ensure both the lifeguard's and the guest's safety.

Utilizing a deep-water rescue is particularly critical because simply attempting to reach out may put both the rescuer and the victim at risk, as the person in distress may grab onto the lifeguard, leading to a situation where both may end up struggling in the water. Therefore, the skills learned in deep-water training are essential for managing rescues in these high-risk scenarios.

The other methods, while beneficial in different contexts, are not suitable for a victim who is submerged and at a distance. Surface dives are typically used for individuals who are underwater but within reach; front dives focus on rescuing someone closer to the surface; and two-guard assistance involves teamwork for rescues but does not specifically address the challenges of reaching a victim who is submerged beyond arm’s reach.
