Today's buildings are getting taller and taller, so the reliance on elevators is also increasing. The quality of the elevator directly affects the safety of people's lives. If the elevator encounters such a terrible situation, how should we deal with it ?

• In fact, as long as the elevator is properly maintained, it is still a fairly safe device. In order to ensure the safety of the people, many countries have elevator-specific regulations. For example, the elevator must be equipped with an alarm button, an open (close) door button and an emergency stop button. Some elevators also have equipment such as intercom, backup battery lighting, etc. Many elevators also have overload warnings to prevent accidents caused by excessive weight, and most elevators are equipped with CCTVs, so that people outside the elevator can see what is happening in the car.
• Although the probability of elevator crashes in the world is not high, when you are in a narrow space like an elevator, and the speed of the stall and fall is so fast that you will not have time to respond, it is best to have some self-help before the accident occurs. method, just in case.
• Many people think that when the elevator falls, just jumping up at the moment of touchdown can reduce the impact force and reduce the damage, but this is wrong. It will enter a weightless state of "free fall", just like when astronauts come to outer space, so it is impossible to squat down and make a "jump up" response. The "bounce time" that people can maintain is very short, and it is very likely that the impact will be aggravated when they land. In addition, if you successfully jump up in a weightless state, your head will violently hit the top of the elevator, which is also a disaster, because we have no way to estimate which part of the body will land first during free fall, nor can we judge whether the jump is up or down. Where will it hurt later, plus it is too difficult to jump.
• Therefore, if you unfortunately encounter the problem of elevator falling, first of all, if you have a bag, or have boxes or boxes around you, quickly put them on top of each other and stand up. There is some buffering effect.
• If there is a handle in the elevator, please hold the handle tightly with both hands to avoid falling down due to the unstable center of gravity, and keep your back and head in a straight line against the wall, using the wall as a protective wall for the spine, to avoid the spine landing on the ground It was a huge impact at that moment. Finally, the knees are slightly bent, showing a bent posture. Because the ligaments of the knee are very elastic human tissues, they can withstand the pressure of strong impacts.
• In addition, when you find that the elevator is falling rapidly, you can also press all the floor buttons, which is also a "fall prevention command" that can effectively start the elevator.
