When should a rescue diver abandon a rescue attempt?

A rescue diver should abandon a rescue attempt when safety is compromised for the rescuer. The primary responsibility of a rescue diver is to ensure their own safety first. If attempting the rescue puts the diver at significant risk—due to factors like rough water conditions, fatigue, or an unstable environment—then proceeding may lead to two victims instead of potentially saving one. The ability to respond effectively relies on the diver's own safety and well-being, allowing them to assist others when it is safe to do so.

Other aspects, such as signs of distress from the victim or the water temperature, may indicate different considerations for the rescue, but the diver's safety should always be the foremost priority. Remember, if the diver is in danger, they cannot provide assistance effectively, and thus must evaluate their position carefully before deciding to continue or abandon the attempt.
