Elevators are complex mechanical and electrical equipment. A small fault will cause the car to stop suddenly, the door will not open, etc., causing people to be trapped. Severe cases may occur such as rushing to the top, squatting at the bottom, sliding the car, etc., resulting in crushing and injuring passengers, or even death. These failures are mostly related to the untimely maintenance of the elevator. Although some users have signed maintenance contracts with relevant maintenance units in accordance with the requirements of the quality supervision department, due to the payment of maintenance fees or the professional ethics of maintenance personnel, the maintenance The company "only repairs, not maintains", resulting in frequent elevator accidents.

When the elevator fails, the safest behavior for the trapped people is to stay in the elevator and wait for professional rescue. But in fact, due to the panic of the trapped people and the untimely rescue, the trapped people will often force the door or climb out of the elevator from the top by themselves, which will bring greater danger. Fear arises.
