A climbing harness should be retied routinely just as a rope should, but if your harness ever breaks or you need to rescue someone who is not wearing a harness this method can help you in a pinch. Using tubular webbing which is something climbers should always have on hand, one can make a seat harness. The following are five steps to quickly tie a climbing harness.
Find a piece of webbing that is 7 to 9 feet long. This will depend on how large the person is using the harness.
Tie a water knot with the ends of the webbing so that it creates one big loop. Do this by making a loose overhand knot with one end of the webbing, then take the other end of the webbing and insert it into the loose overhand following the curves of the knot. Pull tight so that the knot has the two ends coming out on opposite sides.
Wrap the webbing around the back of the person with one strand above the hips and one below.
Reach for the lower strand and bring it between the legs and to the front of the body.
Attach a locking carabiner to the three meeting strands in the front of the body, near the navel. You now have your makeshift harness.
