What to do if you are trapped in an elevator during a power outage

1. Stay calm

In most cases, passengers are trapped in the elevator car due to power outage or malfunction. At this time, the elevator car is stuck between the upper and lower floors. The space in the car is small and the passengers are unfamiliar with each other, which can easily lead to fear. At this time, the most important thing is to stay calm and don't panic. The trapped passengers should comfort each other.

2. Press the elevator's emergency call button immediately

When trapped in an elevator car, passengers must immediately press the alarm button or intercom button on the control panel in the car to call for help, and contact the property and elevator maintenance personnel as soon as possible. They can also use a portable phone to call the rescue number posted in the elevator to inform the location of the faulty elevator and a brief on-site situation.

3. Never smash the elevator!

After getting in touch with the rescuers, just wait patiently and take care of the elderly, the weak, women and children in the car. Usually the rescuers will arrive at the scene within 30 minutes.

4. When you hear someone outside, knock on the door and call for help!

If you call for help but no one comes, the most important thing to do is to stay calm, save your energy, and wait for help. If you hear someone outside, you can knock on the car door rhythmically and continuously to call for help.

5. Don’t smash the ladder! And dissuade others from doing so

Remember! Don't smash the ladder, it's very dangerous! If you force the elevator door open, it is more likely to cause the elevator to fall suddenly due to circuit problems! Therefore, be sure to wait patiently for professionals to come to rescue! !

At the same time, discourage others from trying to pry open the door or use gravity to break through it to escape. The safety window on the roof of the car is not an escape hatch, and it is very dangerous to escape alone without the help of professionals.

Self-rescue methods for elevators trapped during power outages

1. Never try to force open the inner door of the elevator. Even if you can open it, you may not be able to reach the outer door, and it is certainly not possible to open the outer door to escape safely. The grease on the outer wall of the elevator may cause people to slip.

2. If there is an emergency exit on the elevator ceiling, do not climb out. Once the exit panel is opened, the safety switch will stop the elevator. But if the exit panel is accidentally closed, the elevator may suddenly start and make you lose your balance. In the dark elevator shaft, you may be tripped by the elevator cable, or slip on grease and fall from the top of the elevator.

3. If you are trapped in an elevator in a commercial building late at night or on a weekend afternoon, it is possible that no one will approach the elevator for hours or even days. In this case, the safest thing to do is to stay calm and wait for an opportunity to call for help. Listen carefully to the movements outside, and if there are pedestrians passing by, try to attract their attention. If that doesn't work, wait until work hours and then knock on the door to call for help.

Is there a backup power supply in case of a power outage in the elevator?

Community elevators do not need backup power supplies, and national laws do not explicitly require backup power supplies. The national civil building electrical design has requirements. Civil residential buildings above 10 floors are designed according to Class II electrical loads. They must have two power supplies, normal power supply and backup power supply. There is an emergency power supply in the elevator to power emergency lighting and alarms. If there is a sudden power outage, maintenance personnel must arrive within half an hour after receiving the notification to release the person. The biggest consequence is that there is no danger to the person. The power supply system should not cause power interruption in the event of power or line failure, but the country has no clear legal provisions that elevators must be equipped with backup power supplies. Of course, if there is a sudden power outage or a power supply line failure during the operation of the elevator, the elevator will automatically stop running and there will be no danger.

Will I suffocate if I'm trapped in an elevator during a power outage?

If you are trapped in an elevator due to a power outage, you will not suffer from oxygen deficiency. This is because according to relevant national standards, elevators must have enough clearance and cannot be completely closed. The clearance cannot be less than 1% of the net usable area of ​​the elevator. Therefore, if you are trapped in an elevator due to a power outage, do not worry about the danger of oxygen deficiency. You should call for help in time.
