Take a look at the video sent to us by Larry Mullin of Fairfax County FD. The video shows a technique used when attempting to rescue a suicidal person who is about to jump off of a bridge. Apparently this is for when somebody like, I don’t know, a trained psychologist is unavailable and the jumper is patient enough to wait idly by as you set up two rope rescue systems. I’d love to know what you do after you have them. Raise them back up? Lower everybody into the water? Who knows?
I’ve never had to do this type of “rescue”, but I don’t want to be hanging on to a person who wants to die for an extended period of time with no other means of attaching to them. If you’d like to know why, take a look at the second video. Which will also serve as a good pitch for some type of auto locking descender.
