What type of rescue is considered risky and should be approached with caution?

The rescue of a swimmer who is fighting back is considered particularly risky and should be approached with caution because the distressed swimmer may be panicking and could inadvertently pose a danger to the rescuer. When a swimmer is in distress and fighting back, they may thrash about or react unpredictably, which can lead to a situation where the rescuer themselves could become in danger. In these circumstances, the swimmer may attempt to grab onto the rescuer or push them under the water in an attempt to save themselves, making it extremely important for the rescuer to use techniques that create distance and utilize flotation devices whenever possible.

In contrast, rescues involving swimmers close to the edge or conducting training exercises typically allow for more manageable scenarios, as these situations often present less risk to both the rescuer and the individual in distress. While rescues involving multiple victims can be complex, the primary concern with a fighting swimmer is the unpredictable and hazardous nature of their actions which requires careful planning and execution to ensure safety for both parties involved.
