The elevator plummeted from the 35th floor, and the woman staged a textbook escape, what dangers may

In today's society, there are more high-rise buildings, and when the floors are relatively high, many elevators are installed, because it is a bit too troublesome to take the stairs. However, there is a certain risk in taking the elevator, if the elevator fails, it may cause some injury to people, and in serious cases, it may lose life. This scene happened in Fuzhou, Fujian Province, a lady took the elevator as usual, and when she felt that the elevator was weightless, she quickly pressed all the floors, and quickly walked out of the elevator when it stopped on the 12th floor.

This series of operations has made a lot of praise, and the lady is really calm and calm.

On December 22, in Fuzhou, Fujian, a lady entered the elevator as usual, and soon found that the elevator had a feeling of weightlessness, and there was also a sudden drop, so the lady quickly pressed all the remaining floors, and then went out in time when the elevator stopped on the 12th floor. After the lady stepped out of the elevator, the elevator door was smashed and she was not harmed as the lady reacted quickly.

Second, the danger that may occur when taking the elevator is actually when taking the elevator, it is possible to cause injury to us, especially when the elevator breaks down. When the elevator breaks down suddenly, when we enter or exit the elevator, if the elevator suddenly descends or rises, it may cause irreparable damage; If the elevator suddenly rises or falls in the elevator, it may also cause us some damage if the elevator suddenly rises or falls.

3. When encountering elevator failures, what should we do When encountering elevator failures, we cannot shout and maintain a certain amount of physical strength. If you find that the elevator is weightless or too fast, you must quickly press all the floors, and the body is only close to the inside of the elevator, if there is a railing, you must hold the railing, and if you don't, you must hold your neck with both hands, and bend your legs slightly, so as to protect your own safety as much as possible and wait for help.

Elevator rides can be very dangerous. For example, the elevator suddenly falls, the elevator suddenly loses power, the elevator stops where it is not on the ground, and so on. Therefore, when we take the elevator, if there is danger, do not panic, we must be calm and calm.

Hold your head in your hands, lower your center of gravity, press the elevator distress button, and wait quietly for rescue.

A rapid descent of the elevator will occur. The elevator is stuck in the middle of two floors. The elevator doors won't open. There is no signal for a power outage in the elevator, and the elevator power failure is locked inside and cannot get out, etc., these can happen.

When taking the elevator, there may be a danger of stopping or descending rapidly, in this case, we should respond calmly, half-squat to support the handle, and wait until it is stable and then call the distress number to wait for rescue.

When taking the elevator, there will be a lot of dangers, for example, the elevator will fail, which will also cause many people to be trapped in the elevator, and then there will be a sudden fall, and then when taking the elevator, you must pay attention to protect your own safety, and master the corresponding escape skills.

There are many direct primordial allergens that lead to the risk of elevators. Taking the recent accidents as an example, the property side said that either the operation was not in place, or it was still in the commissioning stage. Behind the true and false statements, a core problem is exposed, that is, the maintenance standards and responsibilities of elevators are still not clear enough.

For example, in the Zhanjiang elevator accident, some people in the industry pointed out that China's current "Elevator Manufacturing and Installation Safety Specifications" are defective in the implementation. If the specification requires that the elevator should have an upward overspeed protection device, it is considered that as long as the brake does not brake directly on the traction wheel through the intermediate shaft, it is deemed that the elevator has an upward overspeed protection device.

Because the elevator is aging, there is no daily maintenance, so it will occur frequently.

It may be that these elevators have existed for a long time, so they will lead to disrepair and will lead to such failures.

If the elevator suddenly falls when taking the elevator, the following mistakes are handled in () aThe knees are in a bent position.

b.Hurry up and press the Jingheng button on each floor.

c.The entire back and head are close to the interior wall of the elevator in a straight line.

d.Knock on the door in a panic (correct answer).

Speaking of a realistic question, I just want to ask you what you relied on to grasp that the elevator was about to fall before the elevator fell to the ground? Let's put it this way, before the elevator falls to the ground, he has a lot of heavy protection, the first speed limiter, he will break the safety switch if he exceeds the rated speed, and at the same time will link the machinery, that is, the safety gear, he will hold the guide rail, so that the elevator will not fall, if it falls I can only tell you not to stand in the elevator **, people lean on the car wall, half squatting test, people do not panic, impatient, just keep a good psychology. You should start with one layer, quickly press all the layer buttons, squat with your legs slightly flexed, and your back against the wall, this position will try to protect your spine and knees as much as possible when hitting the ground.

Many times, we often subconsciously look at problems from the perspective of God, and it is difficult to experience a certain problem personally, and the result of this is that we often measure problems through life experience, the so-called "empiricism" or "stereotyped thinking"! For example, the elevator fails, of course, we will not dare to dare to have the opportunity to experience what it feels like to have an elevator failure, in fact, there is nothing special, theoretically, if the elevator fails on the 20th floor, there is no difference between you jumping from the 20th floor! Don't raise the bar here to say that the elevator has friction, and the bottom of the elevator has various cushioning effects, etc., this kind of lifting the bar is meaningless, and it is no longer discussed.

We will only discuss the hypothetical scenario of an elevator in free fall! Then the question is very simple: suppose you jump from the 20th floor, and you can jump at the moment when you are almost on the ground, and then Lingshi Town may not be thrown to your death?

We can gradually rise from low to high and understand a little bit. Jumping from the first floor shouldn't be too much of a problem, you have the opportunity to buffer the time of contact with the earth by "jumping", and you won't fall to death, at most you will be injured! Then there is the second floor, the third floor, all the way to the 20th floor.

You will find that this is the process of quantitative change, specifically to jump from several floors will fall to death, we can't be sure, but jumping above the 5th floor is basically no way to survive! The most important point: in a free-fall elevator, are you sure you can jump?

You can't jump unless you squat before the elevator fails! In a malfunctioning elevator, it's the equivalent of stepping on a board and jumping from a high altitude.

Death cannot be avoided, because there will be such a high inertia, and it will cause a very serious impact, and the damage is relatively high.

No, this situation is very dangerous, and if the posture of the jump is not correct, it can lead to death at any time.

Unlikely, because when a person is descending in an elevator, there is simply no way to stand up straight, and there is no way to pick up.

When the elevator falls, due to the principle of inertia, you can hardly jump with your eyes, and how do you determine at which second the elevator will hit the ground, and what is the correct way to do it?

1.First of all, if you encounter a sudden rapid fall of the elevator, you must adjust your mentality as soon as possible to reduce your panic, otherwise your brain will be blank and difficult to protect yourself.

2.Then no matter how many floors you are on, even if it is dozens of floors high, first you should first light up all the floor buttons below the floor you are onPress from the bottom to the top。Because the elevators can only be controlled, there is a chance that the elevator may stop on a certain floor in the middle, reduce the height of the fall, and reduce the harm to life.

When the elevator falls, if the emergency braking loses its effect and the elevator continues to fall, can the jump be avoided?

Let's assume that death can be avoided with this approach

Then the condition that death can be avoided is to accurately judge the time when the elevator lands and master the time when it needs to jump.

I think this probability is very small, the first is to judge the time of the elevator landing, usually we can see the elevator to the bottom of the prompt, but it does not mean that the elevator landed, the depth of the elevator shaft is generally not clear to non-professionals. As a result, we can't predict when we need to jump. In this way, even if this method can be avoided, the chances are very, very small.

Again, from the principle of mechanics, when the elevator falls, it will produce a downward force, and only by reaching an upward force of the same force can the safety of passengers in the elevator cabin be guaranteed. If you fall from the 20th floor, there is only one upward power support with the same 20th floor falling power. We knew that the elevator was falling very fast, and even if I had a few seconds to jump up, it would be difficult for me to jump to such a height.

Inése Hens, a physicist at the Gravity Research Institute of the Gede Society in Germany, gave three reasons: the elevator falling process is often extremely short, and people may not have time to react at all; It just jumped at the moment when the elevator touched the ground, and the timing was difficult to grasp; Even if you jump, the rate of jumping is difficult to reach the level of the elevator falling, so the injury is difficult to avoid.

If the elevator falls and jumps up a second before it hits the ground, will it survive?

Even if you can jump, you won't be unscathed. After all, the total process is still free fall. The time spent in the air is also very short, so can you ensure that you are in the air when the ground is facing the recoil force of the elevator?

No, you will still be hurt. Just like you are on Earth, no matter what you do, you follow the Earth. Although the effect is not the same, the single principle is the same.

If you catch it, 80% of it won't hurt, and if you jump, it's probably useless because you can't stay in the air, and you will land when the elevator lands.

What about after the jump?

Or free fall, the danger is the same, the consequences are the same.

Internal forces do not do work.

It's hard to say this question, it depends on whether you fell from the 2nd floor or the 20th floor. The 2nd floor is fine, but you didn't react so quickly when the 20th floor fell, and you will still be hit by some materials when you react.

No, Galileo's free-fall experiment tells us that you and the elevator will fall at the same time, but your feet are not on the elevator during the fall. As for being unharmed, looking at how many floors this elevator is, the height must be large, and the fall should be worse. . . Hope it helps.

An upward bouncing force is required to slow down the body instantly, which requires a lot of bouncing force. Humanity can't do it at the moment.

Theoretically, if you jump more than the second you hit the ground at the moment you fall from the 5th floor, and you can stay in the air for a second second, congratulations, you survived.

How hard do you need to jump to make your speed suddenly become zero when you land, this force is enough to push you to death.

Usually we all know that the elevator is inseparable from life now, and the elevator has also brought us a lot of convenience, but some people are worried about the elevator falling, so is the probability of the elevator falling? The elevator in the community fell from the 16th floor to the 1st floor, causing many injuries? For this question, many friends want to know the answer, let's find out quickly.

Is there a high chance that the elevator will fall.

Not too. Each straight ladder is pulled by wire ropes, generally 5-8. The number of wire ropes is calculated based on the friction coefficient of the traction wheel and the load of the elevator.

As we all know, the wire rope is difficult to break, even if one or two of them are broken, the elevator will not fall, and the rest of the wire rope will work normally. People often hear, or have encountered the elevator from a dozen floors suddenly dropped several floors, in fact, this is not "falling" but the elevator "slide" phenomenon, that is, the elevator in the process of operation to detect a system problem, the automatic reset measures, is the elevator self-adjustment phenomenon. The up and down speed of the car is monitored in real time by the speed limiter, and once the car is out of control and overspeeding, the speed limiter will start the safety gear and immediately stop the car system on the guide rail.

The correct posture to avoid danger when an elevator falls is.

If there is a handle in the elevator, hold the handle with one hand, and the whole back and head are close to the inner wall of the elevator, in a straight line, and the knees are bent in a bent posture. Because you don't know when the elevator will hit the ground when it falls, and you are likely to die with a broken body when you fall. Don't panic, keep a cool head and take action.

Quickly press all the buttons on each floor, and when the emergency power is activated, the elevator can stop immediately and continue to fall. If there is a handle in the elevator, please hold the handle with one hand, and the entire back and head should be close to the inner wall of the elevator, and use the elevator wall as a spine protection to fix the position of your person to prevent falling. Bend your knees, tuck your toes up, and inhale.

Ligaments are the only tissues in the human body that are rich in elasticity, so the knee bend is used to withstand the stress of heavy blows and minimize injury.

What is the cause of the elevator falling.

1. Stop and automatically return to the base station during operation: In the process of operation, once the elevator fails, the elevator will automatically choose the nearest flat floor or return to the base station (usually the first floor), open the door and release people. At this point, passengers may mistakenly think that the elevator has fallen to the first floor, but in fact, this is a way of protecting the elevator, and if you press all the floor buttons at this time, it will not be useful and may even cause interference.

2. Slight fall due to weighing device error: the elevator has its own weighing device, which will provide starting capacity according to the weighing information. When the elevator is just started, the force provided by the motor is not enough to pull everyone up, and there will be an error in the weighing device, and the elevator will fall slightly, which is normal.

3. Brake failure or elevator overload causes falling: This is the real elevator fall accident, but in the actual situation, the elevator's anti-fall and anti-overspeed system will brake urgently, which can protect our lives, so there is no need to panic.
