Elevator safety science knowledge

Nowadays, elevators can be seen everywhere. Whether it is housing, shopping malls, or subway stations, elevators have gradually been integrated into our lives. As elevator rooms become more and more popular, elevator safety knowledge is also in urgent need of popular science. At a critical time, knowing some elevator first aid knowledge can save a life.
1. Elevator power outage
In general elevators, there are many safety ropes on the car, and the safety factor is very high. Therefore, elevators generally do not fall off the elevator shaft. The elevators are equipped with anti-fall safety devices. Even if the power goes out and the lights go out, the safety devices will not fail. There are generally instructions in the elevator to tell you what to do if this happens. Most elevators have emergency bells. You should press this first to tell people around you that someone is trapped in the elevator. If there is a signal in the elevator, you can make a phone call. You should first follow the instructions in the elevator and call the elevator fault helpline. If there is no one on duty on the call for help, call the police. Tell the other party where you are.
2. If the safety rope on the elevator is broken
Of course, this situation rarely occurs. People in the elevator should take some protective actions to avoid serious injury to the body. At the same time, there are buffers at the bottom of the elevator groove, which can also reduce the impact speed when falling, so fatal accidents occur. probability is very low. The purpose of taking protective measures is to avoid damage to the human brain, spine and heart caused by the impulse at the moment of the elevator landing. The details are as follows: Do not stick to the elevator door in the elevator, and keep a certain distance. In order to buffer the impact, you should mainly use your toes to land on the ground, with your heels raised, so that less impact can be transmitted to the legs along the heels; at the same time, the knees are bent, the impact is absorbed by the knees, and the direction of the impact is changed to avoid transmitting it to the spine as much as possible. Going up, it also protects the brain and heart from injury. If there is a handle in the elevator, be sure to hold the handle tightly, so as not to fall due to the unstable center of gravity. The main purpose of this method is to sacrifice the legs and arms in exchange for the spine, heart and brain to be spared. Of course fractures can occur.
3. After the car door and the landing door of the elevator are closed, the elevator does not start running
In this case, you can first press the door open button on the control panel to open the elevator, and then press the door close button to close the elevator door to see if the elevator has cleared the fault and continues to run. This can be repeated once or twice, or you can use your hand to help close the door. If that doesn't work, just press the door button to open the door and let people go. You can notify the elevator management department by ringing the alarm bell or telephone, and repair it by professionals.
4. The elevator stops and does not open the door after running, and is trapped in the elevator car
In such a situation, you must be calm, because the elevator is a mature and safe transportation equipment, and "stopping the elevator" is a safety protection measure for the elevator to operate. At this time, the safe and effective self-rescue method is to inform the elevator manager through the alarm button on the control panel or the telephone, and the elevator professional can rescue it, or you can request 110 for rescue.
It is not recommended to forcibly open the door or rescue yourself from the safety window on the top of the car. Because climbing out of the car does not mean rescue, most passengers are unfamiliar with the elevator shaft and elevator structure, and blind self-rescue often causes greater danger.
5. After entering the car, the elevator starts running without closing the elevator door, and the speed is getting faster and faster
In this case, you should not panic, and you must not rush to escape from the car. The correct thing to do is to keep all passengers as far away as possible from the car door and bend their knees. Because the car will stop suddenly when it exceeds the rated speed or reaches the end station, doing the knee bending action can reduce the discomfort of the human body to the "emergency stop".
