Do not step on the rope whether you are wearing socks or barefoot. Stepping on it will allow some invisible sand particles to penetrate into the rope, and slowly cut the rope skin or rope core fiber as it is used. In addition, you must be very careful not to step on the rope when wearing crampons, because the surface of the rope cannot be seen with scars, but the nylon fibers inside may have been cut.
Try to avoid pulling the rope over rough or sharp terrain. When doing rappelling, it is best to wrap the part where the rope and the rock corner contact with cloth or rope. The rope must not pass directly through bolts, fixing points, umbrella straps, and slings. Rubbing with these things hurts the rope. Do not hang two ropes into the same hook and loop (except for double ropes) because the ropes will rub against each other. Do not tie the rope to the tree, it is not good for the rope and the tree. Climbing in damp or icy places, (such as climbing a stream or climbing on ice and snow) should use waterproof treated rope. The wet rope decreases in strength and wears quickly.
To descend correctly, don’t use the method in the movie. The temperature generated by the high-speed descent will damage the rope skin; the jumping sag will cause a very large and unnecessary load on the fixed point and the rope. If it is a group teaching, it is best to drop in batches, with at least 5 minutes between each batch. Climbing down is easy to damage the rope, unless necessary, you should try to drop down the rock wall as much as possible.
