Which water entry technique should be used to approach a nearby guest with suspected spinal injury?

When approaching a guest with a suspected spinal injury, the safest water entry technique is to use the ease-in entry method. This technique minimizes disruption in the water and allows the lifeguard to enter gradually, which is vital when dealing with a suspected spinal injury. By easing into the water, the lifeguard can maintain full control of their movements, reducing the risk of creating waves or splashes that can exacerbate the guest's condition.

The ease-in entry also allows the lifeguard to assess the situation and reach the guest without causing further potential harm. This careful approach is essential in spinal injury scenarios, as rapid or aggressive movements can lead to increased instability for the injured person and further injury.

In contrast, techniques such as the stride jump, feet first entry, and shallow dive may introduce unnecessary risk by creating turbulence in the water or entering in a way that could compromise the injured guest's safety and stability.
