Today's buses generally open the door through an electrically controlled switch that controls the hydraulic lever above the door. Power is provided by air pressure, and the control part is implemented by a circuit.

If a bus accident such as spontaneous combustion damages the circuit, the door cannot be opened. At this time, the emergency switch of the vehicle must be used to open the door.

In the process of escape, we must also pay attention to maintaining a low posture. There was a fire on the bus.
