First, the correct use of safety ropes
1. Fix one end of the escape rope or escape ladder to a firm object, and hang the other end on the seat belt or around the waist, fasten the safety hook, and throw the lifeline down the window to the downstairs.
2. Put on protective gloves and hold the lifeline with both hands. The left foot is hooked on the window sill, and the left ankle is outside the wall. After the person is stable, the left foot moves out of the window.
3, the two legs slightly curved, while the two feet force the wall surface, the arms are straight, the hands are slightly loose, the eyes look down, and slide along the lifeline.
4. When approaching the ground, the right arm bends forward, tightening the rope with two legs, and the two toes are first grounded.
2. What are the structures used for safety ropes?
The safety rope requires a diameter of more than 16mm, and has no uneven diameter, unevenness, uneven strength, kinking, etc. along the entire length, and the processing and finishing is easy and economical. Commonly used structures are:
1. Three-strand reins (three-strand-necked rope): It consists of three strands twisted in the opposite direction of the rope. This is a method of twisting the rope without changing the twist.
2. Four-strand reins (single-rope four-strand rope): Four strands are used, in which a core rope is sandwiched, and the rope is twisted without deformation. The outer circumference of this rope is approximately circular than the three-strand reins, and the core rope is not clamped when the string is made.
3, multi-flower rope: the three strands of reins as a strand, and then smashed synthetic rope, but now rarely used.
4. Six-strand reins: The six strands are sandwiched by a core wire of the same diameter and twisted to form the same structure as the wire rope. However, when all of the fibers are used, they are deformed during use, so this method is rarely used.
5. Braided rope: It is made by using the same number of S and Z strands, which are diagonally intersected with the long direction of the rope. Compared with the tying rope, it has the characteristics of no kinking and the end of the rope is not easy to open.
Third, the safety rope use precautions
1. It is strictly forbidden to use the hemp rope as a safety rope.
2. If the length of the safety rope exceeds three meters, a buffer must be installed to ensure the safety of the workers at height.
3. Two people cannot use a safety rope at the same time.
4. When carrying out high-risk operations, in order to make the high-altitude workers safer on the move, when the seat belt is fastened, it should be hung on the safety rope.
