What method should be used when climbing with a WPFR device?

The method that is appropriate for climbing with a WPFR (Work Positioning Fall Restraint) device is the assisted climbing method. This technique is specifically designed to ensure safety while navigating vertical surfaces. The assisted climbing method involves the usage of a mechanical device that provides support and stability, allowing the climber to move in a controlled manner while minimizing the risk of falls.

This method is essential because it not only assists with weight management while climbing but also provides a reliable means of protection against potential falls. Safety in climbing is paramount, and relying on an assisted technique ensures that climbers are securely positioned and supported at all times, significantly reducing the chances of accidents.

In contrast, using unsupported climbing techniques like free climbing or hitchhiking could lead to dangerous situations, as these methods do not incorporate the same level of safety and security that an assisted climbing approach offers, which is why the assisted climbing method is the recommended choice.
