While on a drill job in Canada the last job after a drill move was to put the safety shack close to the drill site. The Pad builders had build a little stand for it on the the edge of a steep drop off and at the bottom was a bunch of jumbled rocks. (Not an overly safe spot for a safety shack).
After I put it on the stand the young (and very keen) drillers helper went to unhook the 4 point from the shack instead of the main hook. The 2 uphill side ones were a piece of cake but he couldnt reach the downhill ones so he jumps up on the shack roof which unfortunately has 6 inches of snow on it. Realising the bad move I put the longling close to him. As he slides off the roof and gets airbourne somehow he manages to grab hold of the hook before he nails himself on the rocks 30 feet below the shack.
We had a laugh about it over dinner but he did say it was a pretty scary experience.
