While researching a topic for the blog, I found this very interesting video. A couple of guides go to the Sterling Rope Factory to test how heat on belay/rappel devices impact ropes...
A little bit disconcerting...
The dangerous situation that the guide in the video describes is very unlikely. It is extremely unlikely that each climber's device will stop at the exact same point. However, knowing that this is an issue is a good thing. While the situation is unlikely, that doesn't mean it's impossible. Being aware of the potential problem could help keep it from becoming reality.
