Self Rescue Part 2: Rappel Rescue

4/18/2011

In the second installment of the Earth Treks Self Rescue seminar we learned how to swoop down from above and rescue an injured climber. Again, this further proved how inadequate my knowledge base had been to deal with an emergency in the field. A lot of what we learned from this point forward uses common sense and those basic knots, plus the belay escape. While practice is required, with those core skills and some creativity, you can get yourself out of nearly any tight spot.

Here we go with yet another test of my descriptive/technical writing skills...

Rappel Rescue
OR
How to do it on top...
You will need: 1 - 48 inch runner, 1 shirt-ish cordalette, 2 long-ish cordalettes, 3 locking carabiners.
You will need to know: The Mule knot, the Klemheist knot, Prusik knot, and the Munter hitch.

In this situation you are rescuing a follower. You have set up your belay so that the ATC guide is directly attached to the anchor, and when weighted is in auto-lock mode. You will use your rope to rappel down to your fallen partner, then rappel in tandem with them to the ground or to the next belay ledge.

Start with an autoblock on the leg loop of your harness, and a 48 inch runner girth hitched through the two tie-in points on your harness. Tie a knot in the middle of the runner and attach a locking carabiner below the knot. Place another locking biner on the free end of the runner, and attach it out of the way on your harness.

Step 1: Escape the belay

Escaping a belay that is connected to the anchor (but not you) is similar to the process described in the first article in this series.

First, back up your belay. Girth hitch a short cordalette to the leg loop of your harness, and with a Prusik or Klemheist, attach it to the belayer's end of the rope. This way if you let go of the rope at a critical point, the friction knot will catch it. (This is the same autoblock you'd make if you were rappelling solo.)

Then tie off the belay device with a mule knot. No need to wrap it below the ATC this time, since it's already locked off by the climber's weight.

Step 2: Transfer the load

Next prepare to unweight the belay device and transfer the load. Take a second long cordalette and make a Klemheist knot on the (weighted) climber's end of the rope, below the belay device. You will transfer the load to this cordalette while you remove the belay device from the system.

Place a locking carabiner in the master point of the anchor. Attach the free end of the long cordalette to the locking carabiner using a munter hitch. Back it up with a mule knot. Make sure there is tension in the cordalette by sliding the Klemheist up as far as it will go.

Remove the belay device from the master point. If you are using a BD ATC Guide, use the small hole in the front as a lever to release the auto-lock and transfer the weight to the prussic.

Without removing the rope from the ATC, attach it to the 48 in runner you prepped earlier, as if you were going to rappel on it (and you are...) Now clip the rope directly into, and remove the ATC from the master point.

Step 3: Go get your partner

The next step is to remove the Klemheist cordalette and rappel down to your climber. If you or your climber weighs significantly more/less, consider placing an additional Prusik between your harness and the climber's rope. This will prevent too much slipping as you move down the rope.

Double check that the rope is directly clipped into the anchor, then remove the long cordalette by undoing the mule knot and munter. Detach the Klemheist and take the cordalette with you, as well as any extra gear at the anchor.

Slowly rappel down to your fallen climber. Attach the free end of the 48 in runner to their belay loop. This will ensure you rappel at the same rate, keeping you together. If you tied a Prusik on the climber's side of the rope, undo it now. Take the cordalette with you.

Rappel in tandem down to the ground or next belay ledge.

Lessons:
Though a bit more complicated, this process uses a few basic elements: Always back everything up, never untie/unclip completely, and know your knots. Even if you can't remember the step-by-step, if you find yourself in a jam, some creativity and those core elements will help get you safely out.

The patient victim. Soooo glad I saved him...

Again, nice post. A few comments:

Step 1: Tie the "oh shit" knot to the anchor, as I described in the other self rescue article. Also, the autoblock on your leg loop is called an autoblock. You can't tie a prussik or klemheist AND girth hitch it to your harness because both knots require you to pass one end through. Also, you don't need to tie off the device with a mule knot because reversos/atc guides are hands free when in "guide mode" (this info was given to me by an AMGA Rock Instructor).

Step 2: Good. This is the beginning of setting up your counter balanced rappel. Make sure to back up the rappel with the autoblock...you mentioned this earlier :)

Step 3: You got it!

Again, great post! I would do the same thing with the additions of the stuff in Step 1. This technique was taught to me by the guide mentioned above.

Whats next? :D
