Nowadays, high-rise buildings are everywhere, and the elevator failures that follow are even more strange. The phenomenon of trapped elevators has occurred from time to time. Today, Xiaobian summed up the "four major questions about elevator failure", hoping to give friends to senior residents. Bring help!

1. Will the elevator failure fall?

Firefighters say that normal-use elevators generally do not fall, and the bottom of the elevator usually has a safety anti-drop device so that the elevator does not fall. In the event of a power outage, the safety device will not malfunction, so the elevator will not slip out of the elevator trough. Forcing the door during operation, jumping in the elevator, and overloading are the three main causes of accidents in the elevator. In fact, it has been verified by experts that forcing the door and jumping in the elevator will not directly cause the elevator to fall, but it will cause the normal operation of the elevator to take emergency measures suddenly. The emergency stop will cause the elevator door to be locked and cannot be opened; The load is the direct cause of the elevator falling.

2. Will it be suffocated in the trapped elevator?

In a narrow elevator, many passengers are worried about suffocation if they are trapped for a long time. Firefighters said that the elevators currently in use must meet the ventilation requirements before they can be put on the market. Any elevator has a vent, not a seal. In addition, even if the elevator is powered off, the ventilator has a backup power source. There are also many moving parts in the elevator. Some connected locations, such as the junction between the elevator car wall and the elevator car top, have gaps, which are generally enough for everyone to breathe.

3. Can passengers forcibly open the door when they are trapped in the elevator?

The firefighters also reminded everyone that there is no danger that the elevator does not fall. If the passenger forcibly opens the elevator door, it will not only cause the elevator to be unnaturally de-energized, but also increase the abnormal wear and tear of the elevator steel cable and brakes. The effect of emergency braking of brakes and other equipment, there is a hidden danger. In fact, the root cause of the elevator falling is long-term friction loss or man-made damage, so the elevator needs to be maintained once every 15 days. When we take the elevator, we should also pay attention to whether the riding tools are detected on time. Is there an insecure factor?

4. How is the safest trapped elevator safe?

"Keep calm, just to get help and get help and rescue as soon as possible." Firefighters said that there are emergency telephones or intercom systems in the elevator, you can get in touch with the outside world in time, and you can press the alarm bell on the target. Most elevators cover the mobile phone signal. People trapped can call the “Elevator Maintenance Phone” or “Urgent Repair Phone” on the safety inspection qualified sign to ask for help from professional elevator maintenance personnel. You can also call 119 or 110. Ask the firefighters or the police for help. In addition, you can also use the hand to shoot the door, "咚咚咚, 咚咚咚" to tap to send a distress signal.
