FM 5-424 Pole Climbing and Rescue 12-1 CHAPTER 12 Pole Climbing and Rescue Section I. Climbing Pole climbing is necessary in constructing and maintaining overhead exterior electrical systems. The work is not difficult or hazardous if you are careful in selecting, fitting, and maintaining the climbing equipment. You must use sound judgment, use self-discipline, and follow the printed and verbal safety practices that are required in this career field. The art of pole climbing is like any other art—it takes hard work. When you have mastered the art of climbing, you are about 10 percent efficient in your job. To become 100 percent efficient, you must learn to position yourself on the pole so that you can work at ease and with efficiency. INSPECTION POLE Inspect the pole for unsafe conditions both before and during the climb. Unsafe condi- tions include such things as rake (leaning of the pole), shell rot, cracks, breaks, knots, woodpecker holes, and foreign attachments to the pole. Inspect the pole for rot in the center, called heart rot , by sounding the pole with a hammer (if it sounds solid when hit with a hammer, it is safe). When the pole has been in the ground for a long time, inspect it for butt rot by digging down about 6 inches at the base of the pole and drilling a hole partway into the pole base. The shav- ings from the hole will indicate if the pole is rotted. Plug the hole after completing this test. Remove rocks and other objects that are within 10 feet of the pole to prevent injury if you fall. CLIMBING EQUIPMENT Pole-climbing equipment is needed to accomplish exterior overhead electrical dis- tribution work. Basically, there are five main parts to a lineman's equipment—a set of climbers, a body belt, a safety strap, a hard hat, and leather gloves. Inspect your climbing equipment before climbing a pole. The proper procedures for inspecting climb- ing equipment are covered in Chapter 13 and in TM 9-243.

FM 5-424 12-2 Pole Climbing and Rescue CLIMBING PROCEDURES BELTING IN Climbing is an essential part of your job. In order to have your hands free to perform work up the pole, you must be able to belt in at the work position. Practice will help you become skilled in positioning yourself on a pole. The safety strap is the first consideration. It must be carried on the body belt in the cor- rect way. A right-handed person should carry the safety strap in the left D-ring. Snap the double (looped) end so the keeper will face outward nearest the body. The sin- gle end and the keeper will face inward far- thest from the body. This will keep the strap from twisting. A left-handed person carries the safety strap the same way but on the right D-ring. Make initial adjustments to the safety strap
