In the event of an emergency, you need to jump to make a living, and then you connect the torn pieces of bed sheets and the like. With the help of radiators or heavy furniture in the room, you pull the rope and slide it all the way down. This is a lot of film and television works. Lens. These methods have also been used by many people as an option in emergency survival. In fact, this approach looks very good, the actual operation is very difficult, and it requires rigorous training, it is recommended that we do not blindly follow suit.
"Lifeline" is not so easy to use
"The state certified professional rescue ropes, safety ropes, airborne ropes, life-saving ropes, 10-50 meters, and necessary for disaster prevention." After the fire in the Shanghai building, the lifeline began to sell on Taobao. The description of these ropes indicates its purpose: “When a fire or other disaster occurs, one end of the lifeline is secured with a rescue hook, the other end is tied to the user’s waist, and the rope is grasped by both hands and descends slowly down the wall until ground."
From the point of view, the use of lifeline is very simple. However, professionals say that it is misleading for people to survive. Users who once participated in mountaineering and outdoor sports and participated in the Yushu earthquake disaster relief said that “one horse cleans dustâ€: “Don’t say it is on the top floor of the 20th floor, that is, the three or four-story buildings. The decline in accordance with the instructions is the same as the effect of direct jump. Because almost no one has such a large amount of power, it is a step by step rope, unless you have undergone rigorous, professional, hard training.Do not believe, you can ask how many pull-ups you can do? Locking the dangling? Can we single-handedly pull the body? After all, we are not the heroes who fly away."

★ Step 1 to buy the necessary accessories, about a hundred dollars
1 set of stainless steel expansion bolts, about 5 yuan; one hanging piece, about 10 yuan; one plum lock, about 10 yuan; one big steel lock, about 5 yuan, one static rope, about 40 yuan (rope According to the purchase of the building, two or three yuan per meter); 8 word down one, 40 yuan; assuming you are 12 meters high on the 4th floor, then you want to buy 20 meters rope, must be 8 meters more.
★ Step 2 should be set on the wall anchor
First of all, you choose a wall outside your own balcony or outside the window. This wall needs two characteristics: “easy accessibility†and “no vertical obstruction to the groundâ€. In an emergency situation, after breaking the glass of your balcony, your hands and body are easily accessible. The most important thing is that this wall is higher than the top of your head when you will break out of the window.
Next, a hole is drilled in the wall, a stainless steel expansion bolt is punched into the hole, and the hanging piece is loaded into the expansion screw and tightened. Then install the Meihao lock on the hanging piece. At this time, a safety anchor is formed. The anchor point formed by the hanging piece and the Meihao lock can effectively reduce the moment effect and the safety anchor can bear more weight. Finally, hit a double 8 knot on one end of the rope, put the knot of the double 8 knot into the plum lock, and tighten the plum lock. The rope and wall are fixed.
