How can the elevator suddenly lose control and fall to save itself? Is the online statement advisable?
Elevators are basically the vertical means of transportation that urban people contact most now. A normal elevator works 10 hours a day and will start more than 400000 times a year. If you need to take the elevator to and from work, you need to take the elevator at least 8 times a day. When the elevator door is closed, you are blocked in this square meter of space. Have you ever imagined being trapped in the elevator? According to statistics, this happens every 5000 times an elevator goes up and down. But if you want to fall with the elevator and experience free fall, the probability is much lower, because the safety of the elevator is really in place. In case of an accident, how can we save ourselves? Are those statements on the Internet acceptable?
Safety of Elevator
First, the elevator has steel wire ropes. Many people are worried that the steel wire ropes of the elevator are broken. The steel wire ropes of the elevator consist of ten steel wires, and ten steel strands are the steel wire ropes of our elevator. And such a wire rope load-bearing capacity is enough to carry the elevator, our elevator is generally equipped with three. Therefore, the possibility of all broken wire rope almost no. Second, the elevator is equipped with a speed limiter. Once the elevator speed is abnormal, the safety gear will clamp the guide rail to stop the elevator. Third, there are limit switches at the top and bottom of the elevator shaft. When the elevator exceeds the limit position, the traction machine will force the elevator to stop and match the buffer. Even if the brake fails, the impact force can be greatly reduced. In fact, the death rate from elevator accidents is only 0.00000015 percent. Moreover, many accidents are caused by improper use of human beings.
Says circulating on the Internet
In several statements on the Internet, there are those who bend their knees and squat on their backs against the elevator. There are those lying at the bottom of the elevator, and those who say they jump up. So let's simulate the falling situation. The elevator ropes are now all broken, and all the braking devices have no effect. The elevator is like a car rushing to the ground. You are now trapped in the elevator and only have a few seconds to decide.
If you choose to jump upYour body becomes extremely heavy due to the acceleration of gravity, and jumping up is a very difficult thing. Even if you can barely jump up, in these few seconds, can you really grasp the opportunity and jump up a moment before the elevator falls. If you can, then you can choose this way.
If you choose to lie at the bottom of the elevatorWhen you lie on the floor, the impact will indeed be dispersed to your entire body, but the fragile organs inside your body will receive more impact. Of course, when the impact force is within a range, you can protect your fragile head. At the same time, it is indeed an appropriate solution. When it is difficult for you to determine the size of the elevator impact force, you have to make sure that the scattered impact is acceptable to your internal organs and can protect your head. When lying on the floor, it is difficult for you to have any effective means to protect your head.
If you choose to lean back against the elevator and bend your knees and half squat,Back to the elevator, can effectively protect our spine, while helping us to maintain balance, knee squat, is to allow you to reduce the impact of the body to bear. But the degree of reduction is relatively limited. If there is an accident and all safety guarantees are invalid, you should pray that the floor is low enough. As for pressing the button of each elevator, there are actually few users. Moreover, it is better to adjust your posture as soon as possible within the few seconds of falling.
Just like airplanes, although it sounds like many accidents, it is actually very safe to take the elevator and all the safety guarantees do not work. This is much lower than your probability of winning the lottery, which may require you to win several consecutive times. Jackpot. So, don't worry too much. If there is an accident, don't panic and wait for the rescue personnel in the elevator.
