Rap vs. Lower
Posted: Thu Oct 07, 2010 2:59 pm
I've seen a lot of conversation about rappelling vs. lowering after cleaning a route, and I honestly don't see how rappelling is more dangerous. I am not saying that I am correct, I just don't see where the point of danger is in rappelling that is not involved in lowering. So I am going to list my "cleaning checklist" and see if anyone can tell me where I'm going wrong if there is a danger that I don't see and could correct. If you save me that blunt-force trauma at the end of a 40 foot fall in the future by setting me straight, then thank you in advance!
Step 1, gear: I gear up with my ATC with a locking biner and have a two pieces of sewn nylon webbing girth-hitched to my harness with lockers on the ends of each. Each hitch is set approximately on the iliac crest so that they are symmetrical about my sagittal plane. My locker that is associated with my ATC is already set up ready for rope insertion for rappel and checked by my belayer.
Step 2, at the anchor: Once I reach the anchor, I use my webbing that is girth hitched to each side of my harness and I clip direct into the chains somewhere in a place that is not cluttering my existing anchor draws. They are clipped to different load-bearing chains. I ask my belay for slack so that I can test my directs, and once satisfied that I am on direct ( I usually have my belay then take, then give me more slack again to test my directs twice because I'm a coward) I let my belayer know that I am off him/her.
Step 3, disassembling of the anchor: At this point, I am in directly to the anchor chains, I unclip the rope from my anchor biners, tie an overhand hitch low in my rope, and clip it into one of the anchor biners. Then I untie my knot and pass the end of my rope through the rap rings. I tie another overhand knot on the end of my rope that is already through the rings and clip it into the other anchor biner. (If I were to lower at this point, I would instead have tied back in after having passed the rope through the rap rings). Once enough rope has gone through the rap rings that I don't have to worry about the opposite-side weight taking to the ground if I drop it, I unclip the end of my rope from the one anchor, leaving the knot in, then unclip the other end, taking the knot out. The rope is now through the rap rings and I lower the end until my belayer lets me know that both ends of the rope are down. I recover my anchor draws and place them on one of my back gear loops.
Step 4, setting up my rappel: I thread both ropes into my ATC and set it up as a double rope rappel. I take up slack so as to put weight on my ATC and let my girth hitches go limp so as to prove to myself I am on my ATC and not my webbing. (I do this at least twice as well, because again, I'm a coward.) I inform my belayer that I am starting the rappel and to assume fireman's position. Once convinced I am on rappel, I unclip one of my webbings and test my weight on the ATC yet again (seriously, I am a wuss). I then unclip the second and begin lowering down. Once on the ground, I stop sweating.
So I guess in my mind, the most dangerous part of this is when, while I am in direct, I untie from my knot to pass the rope through the rap rings, but I have to do this even if I am lowering, so at the very least, the most dangerous step for rapping is common to both practices. Am I wrong about this? Is there a hidden danger that I am not seeing?
Again, I'm not trying to be a smart ass, just wondering if I'm over-looking something that I might be doing wrong.
