Which action signifies that a Rescue Swimmer (RS) is ready for their pickup?

The action that signifies a Rescue Swimmer is ready for pickup is indicated by a raised arm with the thumb up. This gesture is widely recognized as a signal for readiness and is typically used in maritime rescue situations to communicate to the helicopter crew or other rescue teams. The raised thumb indicates that the swimmer is in a secure position and is prepared for extraction.

Using this signal helps ensure a clear and immediate understanding between the swimmer and the rescuers, reducing the chances of miscommunication during critical moments. This standardization of signals is vital in ensuring the safety and efficiency of rescue operations, allowing all parties involved to act promptly and effectively.
