gblauer wrote: Post incident analysis by the gym owner (he was not a witness, but gathered information through discussions with me and the belayer) suggests the following elements contributed to the loss of control of the rope. The belayer was: 1) Too far from the wall 2) Standing at an incorrect angle to the wall (far off and too the right of the climb) 3) The belayer had her brake hand too far away from her body and attempted to brake by wrapping the rope around her body with her brake hand ending up on her buttocks 4) The belayer had too much slack in the system Items 1, 2, and 4 do not affect the braking power of the ATC. Item 3 does, but if she got her hand all the way to her butt, then the device would have locked. Basically, the whole analysis makes no sense. If she had been standing too far from the base of the route, then, possibly, she got pulled off balance when you fell, and she might have reflexively put her brake hand out in front of her to catch herself, thus preventing he device from locking.

One clear picture that emerges ... Imagine a belayer giving a quite casual or inattentive belay including all 4 points. Due to not being fully breaked off (#3), a load hitting would move rope through the ATC. The belayer reacts by fully breaking as best can be done under the immediate circumstances (#3 - hand to buttocks). But there is already too much rope in the system at this point to prevent the injury - too much rope due to #4 and possibly #1 if the belayer is jerked towards the wall. Bill L

Edit: You probably mean the one of Gail's accident; I don't know so, yes, I'm making an assumption about its height. For the other accident I mentioned, it is probably a little more than 30 feet. Then take off 5 feet or so between the anchors and the highest clips.

Gail said that via this accident she joined the "30 foot club." Sounds like that gym and the gym I mentioned are about the same height.

Here's the thing: The belayer was never jerked into the wall, she was never lifted off the ground. The only sensation I felt was falling. I let go of the top hold, last bolt at chest height and I took a long whip to the floor (there was no "catch" or tug on my harness). I remember falling, I do NOT remember any sensation of being lowered or a "controlled" fall at any time. (And you guys know that I take a lot of whippers, so I do know the difference between being lowered and whipping.) The belayer reported burning on the palm of her brake hand. Frankly, I did not understand the gym owners analysis, because he seemed to believe that the "lead fall" vs. "top rope" fall made a difference in the belayers perception of what was happening. Anyways, Thanks for your insights. Oh yeah, the walls are 35 feet, I am five feet and a couple inches, so I figure I fell 30 feet.

If she didn't get pulled into the wall, then it doesn't matter where she was standing. It also means that she didn't lock off! What probably happened was that she initially didn't have the rope locked off enough, it started to run through the device, and either she couldn't get it under control in time or she simply panicked and never locked it off.

I agree. And it only takes about 1 1/4 second to free fall 30 feet. That's not much time to recover. Edit: I don't understand the distinction the owner's making about "lead fall" vs "top rope" fall. Maybe this has more to do with the accident report than the analysis of the fall.

Jay Bingo. Gail, where were the burns on your belayer's hands? Or were they significantly burnt at all? GO

Gail, I agree with these other yo-yo's that not being locked off is the primary issue. But I would encourage you to also factor in the findings about poor belay position and too much slack. Bill L

The only distinction I could think of was that, if Gail's last clip was above her tie in then the belayer might have been taking in slack, as opposed to feeding it out. Did we ever find out if the belayer uses palm up, pinch and slide belaying?

Basically, yes. I believe a more capable/experienced belayer would have been able to effectively lockoff in the position. Her 2 years of experience, coupled with all of the other stuff mentioned above seemed to have impacted her ability to lock off with her hand outstretched. (away from her body).

That is not how you lock off an ATC -- ever! You bring your brake hand down to your hip. Jay

Was the ATC clipped to the belay loop or directly to the harness?

Jay More to the point, the break hand needs to pull in the opposite direction of the load strand for max breaking. In a typical gym setting, that is down at the hip. But the analysis included that the belayer was in a poor position. Worst case would be if the belayer was way way out from under the 1st clip with the break hand in the general direction of the first clip. Edit: with an ATC.

Bill, it makes no practical difference where the belayer is standing; if she had locked off at the hip, she'd have caught the fall. Even if she had been above the climber, locking off at the hip would be good enough. You and RHJ are just confounding the issue with irrelevancies. Jay
