1. Children cannot ride the elevator alone.

2. It is forbidden to lean on or hit the elevator door.

   Reason: ①The elevator is divided into inner and outer layers of doors

                 ②The inner layer is the car door of the elevator car, which runs with the elevator

                 ③The outer layer is the hall door of each landing

                 ④ Lean on the hall door. If the elevator runs to this floor and opens the door, the person will fall into the car.

                 ⑤If the elevator does not run to the floor, but the hall door accidentally opens by itself, people will fall into the shaft

                 ⑥Although the hall door has a certain thickness, because the door is movable, there are two rollers above and there are sliders below, so it is not as strong as imagined.

3. It is forbidden to overload the elevator, otherwise it will cause the elevator to slip down, and people or objects in the middle of the elevator door will be injured.

4.It is forbidden to use the body or objects to prevent the closing of the elevator door. Being caught by the elevator door will cause various injuries.

5. It is forbidden to jump around or chase and make trouble in the elevator, otherwise the shaking of the elevator will cause a malfunction and trap passengers in the elevator.

6. In the event of an accident such as elevator shutdown or failure, passengers will not be suffocated, because the ventilation holes of the elevator car will be connected to the outside of the building. Usually, passengers feel suffocation, which is caused by excessive tension.

7. It is forbidden to open the elevator door without authorization.

  Reason: ①If the elevator is stuck in the middle of the floor, it will be very dangerous to open the car door

                ②There is a gap of about fifteen centimeters between the elevator and the hoistway wall. Opening the car door may cause passengers to fall into the hoistway.

8. When trapped in an elevator, be sure to stay calm.

   Reason: ①Press the alarm button of the car control panel;

                 ②Press the intercom button or use the intercom to seek help from the monitoring center;

                 ③Call the phone on the front wall of the car and contact the maintenance department of the elevator company for help.

                 ④ You can try to slap the sedan door, and if someone outside hears it, you can ask them for help.
