I believe that everyone is familiar with the escape of bed sheets, so what is the correct escape posture? What is the essentials? On February 5, a fire broke out in a rooftop pedicure store in Zhejiang, killing 18 people. After the incident, many people thought of the "sheet escape" method. Is this trick really reliable? On the morning of February 9, Modern Express reporter invited the firefighters of the Fangjiaying Fire Squadron of the Nanjing Public Security Fire Department Drum Tower Fire Brigade to teach everyone the correct posture of the bed sheet escape. The fire department reminded that it is not a last resort and does not recommend that you choose “sheets to escape†because it has higher requirements for the psychological quality and physical strength of the parties. In the event of a fire, the first thing to do is to call 119. Experimental site Firefighters demonstrate escape "correct posture" At 10 o'clock on the morning of February 9, the reporter of Modern Express came to the Fangjiaying squadron to do the experiment. The firefighters had prepared eight 1.8-meter-long sheets in advance and formed a rescue rope. Is it difficult to escape the sheets? What should I do with the knot between the sheets? What kind of posture should I use when I escape? At the experimental site, the firefighters gave a demonstration to the reporter. Essentials 1: Knot the sheets It is understood that the fire department generally uses rescue ropes during rescue, and the use of sheets to tie knots is similar to rescue ropes. The most common one is "double flat knot". How to play specifically, see the steps: The first step: tie a half knot on the two sheets, pay attention to save the length of the sheets; Step 2: Put the two halves together and form a dead buckle. Tighten. Fang Jiaying squadron Yang Xiangxiang squad leader told reporters that this will tie the sheets, not only can maximize the length of the sheets, but also the knot is not easy to slip, will not easily loose. When you escape, make sure the knot is not loose. In addition to the bed before the knot, but also on the sheet escape rope, every other small section to make a summary, in order to facilitate escape. Essentials 2: Attach the sheets to a stationary object After connecting the sheets with "double flat knots", the next thing to do is to tie the sheets to the fixed object. Because the day's experiment was carried out on a training tower used by firefighters for training, the firefighters tied the sheets to the pipes in the building. If the fire broke out in the residents' home, where should the sheets be tied? The squad leader Luo Jie told reporters that due to the thinness of the pipes in the home, it is generally recommended to tie the sheets to the legs or cabinets to ensure that they can withstand the weight of the escape personnel. The fixed position is chosen, and the most important thing is to tie the knot. At the experimental site, the firefighters introduced two ways of knotting. In the case where the length of the sheets is sufficient, the two knots can be attached at different locations simultaneously to avoid slipping. Specific steps are as follows: First, double winding double knot: 1. Roll the sheets around the cylinder twice 2. The secondary rope presses the main rope to make a knot 3. The secondary rope is pressed against the main rope to make a knot, and it can be tightened. Second, the conclusion: 1. Take the sheet around the column and grab it; 2. Then, after winding the secondary rope around the column, pull it out of the circle; 3. Reinforce the main rope and the secondary rope with a half knot. Note that the secondary rope is 15-30 cm long. Essentials 3: Escape posture After the sheet cover is fixed, the escape position must be correct. In this regard, the firefighters conducted demonstrations for the reporters on the spot: 1. Wrap the sheets around your right foot; 2. The right foot is clamped to the left foot and the foot is pressed against the bed sheet; 3. Grasp the bed rope with both hands and do not slip directly to prevent the hand from being injured by friction. Both hands should grasp the sheet rope and alternately grasp it downwards; 4. At the same time, slowly slide your feet down according to the knot, not too fast, but be sure to clamp the rope. Firefighters reminded that the escape of bed sheets has a higher requirement for physical strength, especially arm strength. Don't look down when you escape, so as to avoid fear of heights. If you have a fire in your home, if the sheets are not long enough, you can escape through the sheets to the downstairs household. Reporter experience Overcome the fear of high security "landing" At the experimental site, the reporter saw the firefighters slipping down from the 3rd floor of the training tower about 8 meters above the ground, and the speed was very fast. Yang Zhuxiang told reporters, "Our firefighters are more experienced. It usually takes about 5 minutes from knotting to slipping, but for ordinary citizens, it is certainly not so fast." Then, if the ordinary citizens escape through the sheets, is it not reliable? The modern Express reporter conducted the experience. Yang Xiangxiang helped the reporter wear a safety helmet and tied the safety rope for the reporter. "First stand on the window sill, grab the sheet rope, the sheets are wrapped around the right calf, and the sheets are placed under the right foot. When the descent is going down, you should use your right foot to buckle your left foot and slowly release the rope." Yang Xiangxiang explained to reporters the main points of operation. The reporter first stood on the window sill, grabbed the sheets with both hands, faced the wall, and then slowly slipped. At first, the reporter's hands clenched the sheets and slowly slid down, feeling that the hands were rubbed by the sheets and felt some pain. "Don't be so slippery, you have to alternate between the two hands, grab the knot on the sheets and step down." Listening to Yang Xiangxiang's prompt, the reporter descended according to his method, and the hands feel more comfortable, the two hands alternate. Hold the knot on the sheets and slowly descend, while your right foot is on your left foot and slowly relax the sheets wrapped around your right foot. Following the sheets, the reporter dropped smoothly to the ground. In the process of "sheets escape", the reporter realized that it is very difficult to grab the sheets by both hands, and it is very difficult to control the weight by the strength of both hands. It is very difficult for ordinary people. Therefore, the bed is wrapped around the right foot and then placed on the left foot, supporting a part of the weight with the foot, feeling a lot of effort. In this regard, the firefighters reminded that if the sheets on the feet are loosened during the process of falling, or if the feet feel very difficult, you can also put your feet on the wall to ease the weight of the upper limbs and slowly descend. Fire reminder Not at all Don't try to escape the sheets Although the experience is relatively smooth, it is carried out with safety precautions. If you slip off the stairs, the situation is much more dangerous. The fire department reminded that the risk of bed sheet escape is high. If it is not a special emergency, it is not recommended for the public. It is recommended that the public should wait for the rescue of the fire department when taking certain self-rescue measures.
