JayB Posted October 3, 2002 Posted October 3, 2002 quote: Originally posted by Fence Sitter: i was checking out and a static 10.5 mill is about 27kn breaking strenght and has an elongation of 3% whereas dynamic ropes have about 9 kn breaking strength, but have 7.5% stretch... No hostility intended here, but the 9kN figure is the not the breaking strength of the rope, but rather the maximum impact force that the rope will generate in a factor two fall. Any UIAA certified single rope will handle a load well into the high 20 kN range before breaking. Count me in with the folks who think there is just no way that either Erden or Goran would have failed to recognize that they were tying in with a static rope. Try actually threading a static rope through a belay device or tying into a harness with one and see what you think. We're all speculating here, but I think Ray had it right - first piece blows, biner on the next piece breaks, and the rest fail. The fact that so many pieces blew in series stongly suggests that at the time of the fall they were not optimally situated in the rock. Could have walked, could have been the original placement, certainly could have had something to do with the characteristics of the basalt. We'll probably never know the full story - but hopefully learning as much as possible about what actually happened will provide some comfort for his friends and family.

This peice was set great, I would have done the same. This peice was five to ten feet below the ledge. Question: how was the #2 placed? would the biner that broke at the end of the quickdraw been pulled onto an edge? anything obvious that would have pulled/pushed the gate open? Another question: have you looked for the missing bit of the biner? I understand the sheriff has the wiregate and the stem, and not the nose and the hook. Erden.

I think the one that I saw is the next to last piece (#2 Camalot) that actually stayed in the crack the biner of which broke. It is certainly possible that he may have kicked the last one at the beginning of the fall... [ 10-02-2002, 11:34 PM: Message edited by: erden ]

Paul_detrick Posted October 3, 2002 Posted October 3, 2002 The #2 was set well,yes it could have been pull in to the side of the crack and the gate open,thus making it fail. I have not been back, but if I get some time I will look for the rest of the biner. Im glad you are working thru this, and wish you the best. I don't know who said it but they were right, things like this make me more aware that I need to watch what I'm doing. PEACE
fixedPin Posted October 3, 2002 Posted October 3, 2002 Another question i would like to raise is the helmet. It looked like a bike helmet when we were climbing, but it was a Meteor climbing helmet. The helmet was destroyed. Not that it would have helped in such a fall, but don't think a climbing helmet should end up in a half dozen small pieces after a fall.

iain Posted October 3, 2002 Posted October 3, 2002 As far as I know the Meteor IS a bike helmet. This was its intended use, sport climbing at the crags. I choose not to wear one more for the reason that if you are hit by one rock you're likely to be hit by two.

Not that it would have helped in such a fall, but don't think a climbing helmet should end up in a half dozen small pieces after a fall. Below are the picture of the helmet, and a link to the Petzl product page. The helmet had a styrofoam lining and a plastic shell on the outside. After the accident, the more rigid plastic shell had separated from the styrofoam, and chunks of styrofoam were strewn about. It is my speculation that the styrofoam got pressed between Göran and the outside shell, therefore popping the shell off the styrofoam lining core of the helmet, and destroying the lining. The fall was so high off the ledge, and the impact so powerful that perhaps only a Kevlar military helmet would have worked, which would have transferred the impact to his spine. The result I am afraid would have been the same. Erden. Petzl Meteor Helmet [ 10-05-2002, 01:32 AM: Message edited by: erden ]
russ Posted October 3, 2002 Posted October 3, 2002 I was hestitant to bring this up out of respect for a fellow climbers death and the grief of his friends,family and climbing community, but there's been enough other sidebars so I will. It took awhile for it to register, but the almost exclusive use of camming devices on the pitch is something a couple of my partners and I have talked about over the years. I tend to protect like Goren did, plug the cams - fast, usually solid. Where my buddies prefer using mostly chocks, or at least as good mixture (I'm talking where you have a choice between 2 acceptable placements). The discussions have influenced me, because I've noticed that I've purposely mixed pro more in the last couple of years. I can't help but wonder what a solidly place chock higher up would have done? [it's been a few years since I led Air Guitar and my memory of the crack has faded - it's probably mostly parallel sided...]

Perhaps the #1 Camalot would have stayed had the placement been in a constriction in the crack. #2 Camalot did stay, except for the biner. Goran did have chocks (wired nuts) with him, however shortly after the start of the climb, the crack widened enough to warrant the use of larger camming devices. Had the biner not broken, and the #1 held, he would have survived. The #3 TCU possibly would not have saved him even if it did stay in the crack, as there was already too much rope out. Erden.
mattp Posted October 3, 2002 Posted October 3, 2002 Russ, I don't think you are being disrespectful. The point that the cams may not be totally secure in the parallel sided cracks at Vantage has already been raised here and your suggestion to place nuts where possible is probably a good one.
fixedPin Posted October 3, 2002 Posted October 3, 2002 Usually on this type of helmet the outer shell is just for decoration and does not add to the helmet strength. Still find it quite disconcerting that the helmet was so destroyed. If a climber takes a tumble or as mentioned before hit by several rocks, what use is a helmet that is only good (possibly) for one impact? I'll take the chance on the spinal injury and save my head.
iain Posted October 3, 2002 Posted October 3, 2002 I believe the Meteor was simply a compromise in safety by Petzl to get helmets on sport climbers and to get over the apparent dork-factor of the more appropriate head protection out there. Use of a polycarb. helmet should be a mark of advanced ability rather than the school marm image some may attribute to it. From erden's description though, nothing would have helped here. Impressive enough that he was wearing any helmet at a so-called sport crag, in my opinion. A very similar fatal head injury at Smith we responded to a few years ago highlighted the need for a helmet on even sport climbs at times. This is getting off track, however, as erden says, it would be difficult to see survival under any circumstances from that distance.
sexual_chocolate Posted October 3, 2002 Posted October 3, 2002 My condolences to all affected by this tragedy, especially to the family and friends of Goran. I have a technical question regarding the incident. I believe it was the #2 camalot which held, yet the 'biner broke. I have a habit of occasionally clipping my qd through a 'biner on my cam sling, which means I have a 'biner through a 'biner. Any chance this might have happened? Would this significantly increase the chance of a 'biner breaking? It seems as though the chances of cross-loading would increase, and now that I think about it, I'm gonna stop doing this, but might there have been such an occurence here? Does the broken 'biner indicate which way the load was applied to it? Has anyone seen it? Just curious. I hope everyone involved is doing ok.

I haven't seen the Metor, but I would have thought that deforming foam would better absorb the impact of a catastrophic impact... hmmm... guess I need to see it

Clipping directly into the cam's sling, IMHO, with your qd is the best way to go. Regarding this possibility in Goran's case, Paul or maybe Erden could ascertain this from the gear that was brought down off the route. Hat's off to you, Erden, for being able to discuss this as extensively as you have. Condolences to all those close to Goran. Greg W
iain Posted October 3, 2002 Posted October 3, 2002 I don't know, it might. The meteor is supposed to destroy itself to absorb energy. At that pace, though, my guess is that it was obliterated w/o helping too much. Subjectively, I think a solid shell would help more. There's only so much you can expect of any helmet in this circumstance.
iain Posted October 3, 2002 Posted October 3, 2002 I think it was the rope-bearing biner on the draw that failed, rather than those attached to the pro?
sexual_chocolate Posted October 3, 2002 Posted October 3, 2002 I really want to see that 'biner. I'm still amazed by the amount of equipment failure involved. More than amazed. Shocked, actually, and that's why I'm so burning to figure this out....
Steven_Kalinowski Posted October 3, 2002 Posted October 3, 2002 I read a report a few years ago in Accidents in North American Mountaineering that sounded similar to Goran's. In this case, someone took a moderate length fall thatpulled the first piece. Apparently, the rope stretched while pulling the first piece and did not have time to recover when hitting the next piece. At this point, it was similar to a static rope and broke a caribiner. Perhaps this is what happened to Goran - how else can you explain the damage to the gear? -Steven

Gordonb Posted October 3, 2002 Posted October 3, 2002 Actually that makes some sense. It doesn't require a lot of gear to fail under a "normal" load. The shock load of a long fall onto a streached rope would be about the same as a static rope fall and could exceed the limit on the 'biner. It doesn't comfort me much with that thought. It might be a good time to invest in some screamers.
iain Posted October 3, 2002 Posted October 3, 2002 quote: Originally posted by Gordonb: It might be a good time to invest in some screamers. I think that might be a bit much. Countless people have had similar falls as this and the pro has performed exactly as needed.

It seems that for the rope to remain in its maximal stretch phase long enough to act as a static line on the next piece of pro, the distance between pieces would have to be quite short, although the speed of the rope would be an important factor....
