The red button of the bell is usually an alarm clock. Don't press it unless there is danger. There are triangle buttons next to the elevator door, one for going upstairs and the other for going downstairs.

Precautions for taking the elevator:

First, the elevator cannot be overloaded. When the elevator gives an alarm, you should take the initiative to quit and wait for the next trip. It is very dangerous to overload the elevator.

Second, when the elevator door is about to close, don't rush into the elevator forcibly to prevent the elevator from closing, and avoid one foot inside and one foot outside, which will be hurt. When the elevator door is about to close, it is forbidden to put your hand into the door gap and try to reopen the elevator. Keep a distance from the elevator door, and pay special attention to prevent clothes or other personal items from being squeezed by the elevator door when opening and closing the door.

Never press panic button when the elevator is running normally, otherwise it will bring you unnecessary trouble. If you need to keep the elevator door open, you should hold down the open button. If you need to carry things, you can ask other passengers to hold down the open button for you.

Fourth, when taking the elevator, if the elevator door is not closed properly, it will run, indicating that the elevator is faulty. Passengers should not take it and report to the maintenance personnel at the same time.

Before coming to the elevator, passengers should first check whether there is a sign of "Elevator Stop Maintenance". If the elevator is under maintenance, this sign should be hoisted and passengers are not allowed to ride.

Six, in the event of a fire, the elevator should be parked on the floor where the fire or fireworks have not spread. Passengers are not allowed to use the electric elevator to escape, but to escape from the safety exit of the stairs.
