When is the signal of a raised arm with a thumb up used by a Rescue Swimmer (RS)?

The signal of a raised arm with a thumb up is used by a Rescue Swimmer (RS) to indicate that they are ready for pickup. This gesture is universally recognized as a way for the swimmer to communicate that they are in a safe condition and that they have completed their assigned task, whether it be retrieving a victim or positioning themselves for extraction. It signifies readiness and assures the recovery personnel that the swimmer is prepared to be taken back aboard the rescue platform.

In contrast, other signals and gestures are utilized for different scenarios. For instance, a raised arm without any indication or a different gesture may signify distress or the need for assistance. Being aware of the specific signals and their meanings is crucial in rescue operations, as effective communication can significantly impact the success of the mission and the safety of all personnel involved.
