I have been busy today trying put together a short video on rope rescue for climbers. That concentrates on escaping the system, which is a skill that if you are going to go on to climb multi-pitch route, or in serious places like sea cliffs then you will need to learn skills like this. In particular even just being able to be able to lock off a belay plate could free up your hands to help yourself.
I once turned up to a rescue where the belayer hand been holding onto the rope for dear life, not wanting the casualty to fall any further for over an hour because he couldn’t lock a belay plate off. The belayer had to wait for others to come to his aid.
The video is here, and there is a short article on cautionary tales about climbing accidents here.
