The consequences of not wearing a seat belt can be disastrous. I. Proper use of the safety rope 1. Fix one end of the escape rope or escape ladder to a sturdy object, attach the other end to the seat belt or wrap it around the waist, fasten the safety hook, and throw the rescue rope down through the window. 　　2. Put on protective gloves, hold the life rope with both hands, hook the sole of your left foot around the window sill, push off the exterior wall with your left foot; once you are stable, pull your left foot out of the window. 　　3. Bend the legs slightly, push hard against the wall with both feet, keep the arms straight with relaxed hands, look downward, and slide down using the life rope. 　　4. When nearly at ground level, bend the right arm forward, tighten the ropes, bend the legs, and let the toes touch the ground first. 　　II. What are the structures available for safety ropes? Safety ropes are required to have a diameter of more than 16 mm, with no unevenities in diameter, twisting, strength, or kinks throughout their length; they should also be easy to process and handle, and cost-effective. Commonly used structures include: 1. Three-strand twisted rope (three-strand nine-ply rope): It is composed of three twisted strands twisted in the opposite direction to that of the rope, and this is a method of twisting the rope without changing its twist rate. 　　2. Four-strand twisted rope (single rope with four strands): It is formed by twisting four strand fibers, with a core fiber inserted among them, into a rope without any deformation. The perimeter of this rope is more circular than that of a three-strand twisted rope, and no core strand is included when making it thin. 　　3. Multi-strand rope: Three twisted strands are used as the constituent strands, which are then twisted together to form a rope; however, this method is rarely used these days. 　　4. Six-strand twisted rope: Six strands are combined with a core wire of the same diameter and twisted together to form a structure similar to that of a steel wire rope. However, when fibers are used entirely, it deforms during use, so this manufacturing method is rarely employed. 　　5. Woven rope: Made by interweaving strands of S-twist and Z-twist in the same number at an angle to the length direction of the rope. Compared to twisted ropes, it features no kinking and its ends are less likely to loosen. 　　III. Requirements for the installation of horizontal safety ropes for holding on to 1. The horizontal safety ropes for holding on to should preferably be made of 6×37+1 steel wire ropes with plastic coatings on their fiber cores; their technical properties must meet the requirements specified in GB/T 1102 \"Round-wire steel ropes\", and they must come with a product manufacturing license as well as a certificate of conformity upon leaving the factory. 　　2. The ends of the steel wire rope shall be fixed to a sturdy and reliable frame, with it being wound around the frame at least 2 times; padding shall be used when it comes into contact with the corners of the frame. 　　3. For the fixed connection at the end of the steel wire rope, rope clamps (also known as wire rope clips) should be used. The clamp plates should be placed at one end of the longer portion of the wire rope, and the number of clamps should be no less than 3. The spacing between the clamps should be at least 6 times the diameter of the wire rope. The safety clamp should be installed about 500 millimeters away from the last clamp; a sufficient length of wire rope should be left to form a safe bend before it is clamped to the main rope. 　　4. The fixing height of the steel wire rope should be 1.1–1.4 m; a fixing support point should be installed every 2 m; the sag of the steel wire rope after it is fixed should be 10–30 mm. 　　5. The hand-held horizontal safety rope is intended solely as a guide rope for workers performing work at heights in special situations, and must not be used as a hanging point for safety belts. It is necessary to regularly check whether the fixing ends or points are loose, and whether the steel wire rope is damaged, corroded, or has broken strands. 　　IV. Precautions for using safety ropes 1. It is strictly prohibited to use hemp ropes as safety ropes. 2. If the length of the safety rope exceeds three meters, a buffer must be installed to ensure the safety of workers working at heights. 　　3. Two people cannot use the same safety rope at the same time. 　　4. When performing high-risk tasks, to enhance the safety of workers at heights while they are in motion, in addition to fastening their safety belts, they should also attach themselves to safety ropes.
