Nowadays, elevators can be seen everywhere, whether it is housing, shopping malls, or subway stations, elevators have gradually been integrated into our lives.With the increasing popularity of elevator rooms, elevator safety knowledge is also in urgent need of popular science.At a critical time, understanding some elevator first aid knowledge can save a life.

1. Elevator power failure

In general, there are many safety ropes on the cars of elevators, and the safety factor is very high.Therefore, the elevator generally does not fall into the elevator slot.The elevators are equipped with anti-fall safety devices. Even if there is a power failure and the lights are 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 first press this to tell the people around you that someone is trapped in the elevator.If there is a signal in the elevator, you can make a call. You should first follow the instructions in the elevator and call for help for elevator failure.If no one is on duty on the call for help, then call the police.Tell the other party where you are.

2. If the safety rope on the elevator is broken

Of course, this rarely happens. People in the elevator should take some protective actions to avoid serious physical injury. At the same time, there are buffers at the bottom of the elevator trough, which can also reduce the impact speed when falling down, so the probability of a fatal accident is very low.The purpose of taking protective measures is to avoid damage to the human brain, spine, and heart caused by the instantaneous impulse of the elevator to the ground.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 impulse, you should mainly use your toes to the ground and your heels to be cocked, so that less impulse can be transmitted along the heel to the leg; at the same time, bend your knees, bend your knees to withstand the impulse, and change the direction of the impact force, try to avoid transmission to the spine, while protecting the brain and heart from damage. If there is a handle in the elevator, be sure to hold the handle tightly so that you will not fall due to unstable center of gravity.The main purpose of this method is to sacrifice legs and arms in exchange for the spine, heart, and brain from damage.Of course, fractures may occur.

3. After the car doors and floor doors of the elevator are closed, the elevator will not start operation.

In this case, you can first press the door opening button on the control panel to open the elevator, and then press the door closing button to close the elevator to see if the elevator is relieved of the fault and continues to operate.You can repeat it once or twice, or you can push it by hand to help close the door.If it doesn't work yet, I have to press the door button to open the door and let people go.The elevator management department can be notified by ringing the alarm bell or telephone, and it will be repaired by professionals.

4. After the elevator is running, the elevator stops and does not open the door, and is trapped in the elevator car.

In this situation, you must be calm, because the elevator is a kind of technically mature and safe transportation equipment, and “stopping the elevator” is a safety protection measure for the elevator's operation failure.At this time, the safe and effective self-rescue method is to inform the elevator manager through the alarm button or telephone on the control panel, and the elevator professionals can rescue or request 110 rescue.

It is not recommended to forcibly open the door or rescue yourself from the safety window of the car roof.Because climbing out of the car is not tantamount to rescue, most passengers are not familiar with the elevator shaft and elevator structure, and blind self-rescue often causes greater danger.

5. After entering the car, the elevator door is not closed and the elevator starts to run, 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 approach is to keep all passengers as far away from the car door as possible and bend their knees.Because the car will stop abruptly after exceeding the rated speed or reaching the terminal station, knee flexion can reduce the body's discomfort with “emergency stop”.
