First, press the button on each floor quickly
When an accident occurs, no matter which floor you are on, you should quickly press the buttons on each floor so that when the emergency power is turned on, the elevator can stop falling immediately.

Second, tight handshake
If there is a handle in the elevator, be sure to hold your hand and fix your position so that you can use external force to stabilize our center of gravity and not fall.

Third, close to the interior wall of the elevator
If there is no handlebar in the elevator, put your entire back and head close to the inner wall of the elevator, so that the upper body is in a straight line, so that the elevator can be used as a wall to protect the spine.

Fourth, knee bending
The knees are bent and the heel is lifted. Because when the elevator falls, it will produce strong vibrations, and the ligaments at the knees are very elastic, which is more stressful than the bones, so you can avoid serious injuries.
