When there is a fire in the car engine, the driver should stop quickly, open the door to let the passengers get off by themselves, then cut off the power supply, take off the fire extinguisher on the car and aim at the fire surface to put out the fire.
When a car is knocked down and a fire breaks out, passengers will be seriously injured or killed because the parts of the knocked-down car are damaged. The first task is to try to save people. If the door is not damaged, you should open the door and let the passengers escape. The above two methods can also be carried out simultaneously.
