Which rescue technique involves using a rigid device to reach a victim?

The technique that involves using a rigid device to reach a victim is the rescue board or reach pole. This method is specifically designed to extend a rescuer's reach without needing to physically enter the water, allowing for a safer and more controlled approach when trying to assist a victim who may be in distress.

Using a rigid device like a reach pole provides several advantages; it minimizes the risk to the rescuer by keeping them at a safe distance from potentially hazardous conditions, such as strong currents or submerged obstacles. It also allows the rescuer to maintain stability and control while trying to reach the victim, making it less likely that the rescuer will end up in a compromising situation themselves.

In contrast, the other rescue techniques mentioned, such as the swim rescue technique or the dolphin rescue method, involve direct physical contact with the water and the victim. While these methods are essential in certain contexts, they do not utilize a rigid device to create that essential reach without entering hazardous conditions. The throw rescue method, while also effective, typically involves a floatable object rather than a rigid device for reaching the victim, focusing on distance rather than an extension of reach.
