1. Differences between fire elevators and ordinary elevators
1.1 Power supply settings
Fire elevators: adopt dual power supply design, one for fire protection, to ensure normal operation in case of fire.
Ordinary elevators: only one power supply, which may not be used due to power outages in case of fire.
1.2 Fire protection function
Fire elevators: with fire protection design, can continue to operate in case of fire, for firefighters to extinguish fires and rescue.
Ordinary elevators: no special fire protection requirements, prohibited to use in case of fire.
1.3 Operation buttons and running time
Fire elevator:
Equipped with a dedicated operation button, after the fire is confirmed, other elevators will descend to the first floor, and only the fire elevator can operate.
The running time from the first floor to the top floor does not exceed 60 seconds.
Ordinary elevator: No such function.
1.4 Drainage facilities and fire telephone
Fire elevator:
Drainage facilities are installed at the bottom of the shaft (sump volume ≥ 2m³, drainage volume ≥ 10L/s).
Equipped with a dedicated fire telephone.
Ordinary elevator: No drainage facilities and fire telephone.
1.5 Limitations of ordinary elevators in fire
No power supply guarantee: power may be cut off during a fire.
Chimney effect: The elevator shaft is prone to become a channel for the spread of smoke and fire, threatening life safety.
Limited evacuation capacity: Only a few people can be carried at a time, delaying the escape opportunity.
Risk of electromechanical failure: People may be trapped due to power outages or failures.
2. How to use the fire elevator
2.1 After arriving at the fire elevator antechamber on the first floor, the personnel shall first smash the glass sheet protecting the fire elevator button with a hand axe or other hard objects, and then put the fire elevator button in the on position. The appearance of the button varies depending on the manufacturer. Some have only a round red button, which can be pressed down during operation; some have two operating buttons, one is black with the English word "OFF" on it, and the other is red with the English word "ON" on it. During operation, the red button marked "ON" can be pressed down to enter the fire state; the technical transformation office building has the former, while the new dormitories in buildings B2 and B3 have the latter.
2.2 After the elevator enters the fire state, if the elevator is in operation, it will automatically descend to the first floor station and automatically open
the door. If the elevator has already stopped on the first floor, it will automatically open;
2.3 After entering the fire elevator car, the personnel shall press the "close door" button tightly until the elevator door closes, and release the button only after the elevator starts. Otherwise, if you let go of the door during the door closing process, the door will open automatically and the elevator will not start. In some cases, it is not enough to just press the door closing button. You should press the button for the floor you want to reach with your other hand while pressing the door closing button. You can only let go until the elevator starts.
2.2 Entering the fire state
If the elevator is running, it will automatically descend to the first floor and open the door. If the elevator has stopped at the first floor, the door will open automatically.
2.3 Operating the elevator
After entering the car, press the "close door" button until the door is completely closed. At the same time, press the target floor button and let go only after the elevator starts.
3. Precautions for fire escape
It is forbidden to use ordinary elevators to escape.
Calmly judge your own position and choose a safe escape route.
If you are trapped, call 119 immediately and inform the specific location.
Tip: The fire elevator is a special rescue tool for fire. Ordinary elevators do not have escape functions. Do not use them in confusion.
