What should I do if I'm trapped in an elevator?
When trapped in an elevator, the built-in alarm bell and intercom system can be used to call for rescue and contact the elevator duty room or elevator maintenance personnel. If no one answers, you can use your mobile phone to call 119 for emergency assistance and wait for firefighters to come to your rescue.
Will there be oxygen deficiency when trapped in an elevator?
When taking an elevator, the elevator car is not a closed space. It has ventilation openings and exhaust fans, which do not cause suffocation. When we are trapped in an elevator, we should remain calm and not panic, just wait for rescue.
How to self rescue when an elevator falls?
In general, when an elevator suddenly falls, it is caused by the breakage of the steel wire rope that pulls the elevator. The speed is 4 meters per second. Once it falls to the ground at full speed, the huge rebound force of the elevator car will shake the internal organs of people, and also cause damage to the legs, spine, and cervical spine.
When encountering an elevator falling, passengers should remain calm and remember not to engage in blind self rescue behaviors such as knocking on doors or kicking, otherwise the danger will increase.
If suddenly trapped in an elevator, one should use the telephone, alarm bell, walkie talkie, mobile phone and other devices inside the elevator to seek help, and avoid turning the elevator equipment by oneself.
If unable to contact the outside world, you can shout or take off your shoes and knock on the door to send a signal for help. If there is no response, do not frequently kick or tap the door, maintain physical strength and wait for rescue.
If the elevator falls or rushes to the top, quickly press all the buttons on all floors. When the emergency power is turned on, the elevator can stop falling further.
If there is a handle in the elevator, holding the handle tightly with one hand can fix the position of the person and prevent them from falling due to unstable center of gravity.
When the elevator falls, the entire back and head are tightly pressed against the interior wall of the elevator, forming a straight line. By bending the knees, it can withstand greater impact pressure.
