The bails performed in this video were from a height of 8 feet with protective matting in place. While training always utilize fall arrest protection when deploying an escape system from any elevation. This should include both a belay line and harness (ideally a full body). None of the anchoring techniques shown in this video should ever be deployed in a real life emergency without first practicing them in a safe and controlled setting. Not every technique will work in every situation. The strength, integrity and therefore safety of a specific anchor is based on many variables. Having more than one option will only increase the probability of being able to escape a hostile environment without injury. Practice to the point where your moves become instinctive - Look for more videos to follow.......

Train, Be Prepared, Stay Safe - SURVIVE!
