What signal does a raised arm with a thumb up represent for a Rescue Swimmer (RS)?

A raised arm with a thumb up is a clear signal used by a Rescue Swimmer to indicate that they are ready for pickup. This gesture is universally understood in rescue operations as a sign that the swimmer is in a safe position and is prepared to be airlifted or retrieved. It conveys a sense of readiness and reassurance to the rescue team that no additional assistance is currently needed and that the operation can proceed to safely extract the swimmer from the water.

In contrast, the other signals do not correspond to this specific gesture. For example, a raised arm with a different position may indicate a request for assistance or other specific needs that differ from being ready for pickup. Recognizing these signals is crucial in emergency situations to ensure effective and timely rescues.
