Nowadays elevators are everywhere, whether it is housing, shopping malls, subway stations, elevators have gradually integrated into our lives. With the increasing popularity of elevators, elevator safety knowledge is in urgent need of science. At a critical time, knowing some elevator first aid knowledge can save a life. The following small series will give you some knowledge of elevator safety.
1. the elevator is out of power
In general elevators, there are many safety ropes on the car, and the safety factor is very high. Therefore, the elevator generally does not fall off the elevator trough. The elevators are equipped with anti-drop safety devices. Even if the power is cut off, the lights will be extinguished and the safety devices will not malfunction. The elevator will firmly clamp the rails of the two emperors in the elevator trough so that the elevator will not fall. There are usually instructions in the elevator to tell you what to do and what to do. Most elevators have emergency bells. You should first drop this and tell the people around you that someone is trapped inside the elevator. If there is a signal inside the elevator, you can make a call. You should first call the elevator for help in accordance with the instructions in the elevator. If the call is not on duty, call the police. Tell the other person where they are.
2. If the safety rope on the elevator is broken
Of course, this kind of situation rarely happens. It usually happens on elevators that have been in disrepair. The people in the elevator should do some protective actions to avoid serious injury to the body. At the same time, there are buffers at the bottom of the elevator trough, which can also be reduced. The impact speed at the time of the 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 landing.
The details are as follows: Do not stick to the elevator door in the elevator, and keep a certain distance. In order to cushion the impulse, you should mainly use the tiptoe to touch the ground and the heel to lift up, so that less impulse can be uploaded along the heel to the leg; at the same time, the knee is bent, the knee is bent to bear the impulse, and the direction of the impact force is changed to avoid transmission to the spine. Go up and protect the brain and heart from injury. If there is a handle in the elevator, be sure to shake hands so that you don't fall because of the unstable center of gravity. The main purpose of this approach is to save the spine, heart and brain from injury by sacrificing the legs and arms. Of course, fractures may occur.
3. What should I do if the elevator does not start after the elevator car door and landing door are closed?
In this case, it is likely that the contact of the door lock electrical contact of this layer is caused by poor contact. You can press the door open button on the control panel to open the door, then press the close button to let the elevator close the door to see if the elevator has lifted the fault. run. It can be repeated one or two times, or it can be pushed by hand to help close the door. If it still doesn't work, just press the door open button to open the door and let go. The property management department can be notified by an alarm or telephone to be repaired by a professional.
4. After the elevator runs, the elevator will not open the door and be trapped in the elevator car.
In this case, we must be calm, because the elevator is a mature and safe transportation equipment, and the “stopping ladder” is a kind of safety protection measure for the elevator to operate failure. At this time, the safest and most effective way to save yourself is to inform the property manager through the alarm button or telephone on the control panel, rescue by the elevator professional, or request 110 rescue.
It is not advisable to forcibly open the door or rescue it from the safety window of the car top. Because climbing out of the car is not equal to rescue, most passengers are unfamiliar with the elevator shaft and elevator structure, and blind self-rescue often poses greater danger.
5. After entering the car, the elevator door starts to run without closing the elevator, and the speed is getting faster and faster.
In this case, you should not panic, you must not rush to escape the car. The correct approach is to keep all passengers as far away as possible from the car door and do knee flexion. Because the car will exceed the rated speed or reach the end station, it will stop suddenly. Doing the knee flexion can reduce the body's incompatibility to the "emergency stop".
