What action should be taken if an anchor is not strong enough?

In the context of swiftwater rescue operations, if an anchor is not strong enough, backing up or tying back is a preferred action as it adds additional security and strength to the anchor system. By incorporating an additional connection or support, you enhance the overall stability of the anchor point, especially in unpredictable environments like swiftwater. This method also allows the rescuers to maintain safety while working in a potentially hazardous situation.

Using a stronger anchor is one approach; however, if the environment limits anchor options or if immediate replacement of an anchor isn't feasible, backing up the existing anchor is a viable solution. Moving to a different location may be necessary in certain situations, but it might not always be practical or safe. Allowing the anchor to break free would certainly compromise the safety of the operation and is not a justifiable choice when stronger support is needed.
