What if the elevator suddenly loses power?

1. If the elevator breaks down and stops running, passengers should try to stay calm. You can use the alarm and telephone in the elevator to contact the property management personnel or call 1 10 for help, and wait patiently for the maintenance personnel to handle it.

2. If the elevator falls freely, press the button on each floor quickly.

3. Knee bending; If there are handrails in the elevator, you'd better hold them tightly. If there are no handrails, you can hold your neck with your hands to avoid neck injury. The whole back and head are in a straight line with the inner wall of the elevator, and the elevator wall serves as the protection of the spine.

4. Don't take improper self-help behaviors such as tearing the door and sliding the door.

There is generally no signal in the elevator, so you can knock on the door and call for help to attract the attention of people nearby and let others call for help.

6. Don't get out of the elevator until the fault is handled and the elevator stops.

Precautions:

After the power failure of elevators in high-rise buildings, the state has not clearly stipulated that elevators must have standby power supply. According to the national code for electrical design of civil buildings, civil residential buildings with floors above 10 should be designed according to the second-class electricity load.

That is to say, there must be dual power supplies (including shared power supply and standby power supply), and the power supply system cannot interrupt power supply in case of power failure or line failure, but there is no clear law that elevators must be equipped with standby power supply.
