Green is a lifelong climber from Colorado who has written more than 20 books about hiking and rock climbing. our editorial process Stewart Green Updated January 29, 2018 Rappelling, the act of descending by making a controlled slide down a climbing rope, is one of climbing’s most dangerous techniques since the climber relies exclusively on both his rappelling equipment and his anchors for total safety. When you lean back on your rappel rope and commit to going down, your safety is completely dependent on your equipment and your essential climbing skills. Rappelling Causes Many Accidents When you climb a route from the base of a cliff, your rope is attached to many points of protection, including bolts, cams, and pitons, which creates redundancy in case of a fall and keeps you relatively safe. But when you rappel, you trust your life to an anchor system which has to be secure for you to be safe. Year after year rappelling accidents account for many climbing fatalities and injuries, making it statistically one of the most dangerous climbing activities you will learn and practice. If there is an upside to the danger of rappelling it is that most accidents occur as a result of the climber’s misjudgment and errors and can be avoided. What Can Go Wrong Rappelling? Rappelling is always dangerous and sometimes scary, especially when you trust your life to the anchors and the rope. When you rappel, lots of things can go wrong including: Your rappel anchors can fail. You fail to tie a stopper knot in the ends of the ropes. Your rope-connecting knot can come untied. You do not use an autoblock knot as a back-up. You might rig your rappel device wrong. Your hair or t-shirt might get stuck in your rappel device. You might lose control if it’s too overhanging. Your rope might cut on a sharp edge. Your rope might get stuck when you pull it. You let go of the rope with your brake hand. Use the Buddy System to Double-Check Many times you will be rappelling at the end of a long day of climbing when you’re tired and it’s getting dark or the weather is turning worse. It’s at those times that you are most vulnerable to fatal mistakes. It’s at those times that you want to not only double-check all your rappel systems but to triple-check them. It’s also best at those times to remember that we always climb as a team. Use the buddy system, just like when you’re swimming or scuba diving, and check each other’s climbing harness and rappel set-up. Each of you should also eyeball the anchors, the climbing hardware, bolts, and slings on the anchors, and make sure the knot connecting your two ropes is tied correctly.
