1. How to correctly call the elevator 
Except for the ground floor and the top floor, there are usually two elevator call buttons on each floor in the middle. If you want to go down, please press the downward button, which is usually marked as "↓". If you want to go up, please press the upward button, which is usually marked as "↑". Remember not to press both buttons at the same time as this will increase the waiting time for the elevator. 
2. You should wait patiently for the elevator. 
After calling the elevator, choose a suitable position and avoid blocking the elevator door. This is to ensure that passengers can evacuate in time. Especially, do not lean against the elevator floor door to prevent accidents when the door opens. 
3. How to safely enter and exit the elevator 
The elevator has arrived. The floor door will automatically open. Follow the "enter from bottom to top" sequence. After those waiting in the elevator get out, you can enter the car. When entering the elevator, do it as quickly as possible. The door opening time of the elevator is generally 4 to 6 seconds. If there are many passengers, you can press the call button or have the passengers in the elevator press the door opening button until all the people have entered or exited. 
4. Precautions when entering the elevator car 
When passengers enter the elevator car, if the elevator door is open, they should check whether the elevator is at the floor level position or whether the car is on the current floor. Especially in the dark at night, they should pay more attention. Otherwise, it may cause injury and they should enter and exit quickly. 
5. In case of a sudden power outage or malfunction of the elevator, what measures should be taken? 
In the event that the elevator malfunctions and suddenly stops operating, the safest course of action for passengers trapped inside the car is to remain calm, seek help from outside, and wait for rescue. Do not attempt to escape from the elevator car through the safety window and enter the shaft by yourself, or force yourself to pry open the door for self-rescue. If the elevator suddenly starts moving at this time, it will pose a great danger.
