Should the Car Engine Be Turned Off When Refueling?
1 Answers
When refueling, the car engine should be turned off. The impacts of not turning off the engine during refueling are: 1. The exhaust may emit sparks that mix with gasoline molecules in the air, potentially causing a fire; 2. It generates a large amount of heat that is not easily dissipated, and sparks from the running engine could ignite it; 3. It poses safety hazards, as short circuits or sparks could easily lead to a fire. Precautions to take when refueling include: 1. Do not re-enter the vehicle while refueling; 2. Avoid refueling during thunderstorms; 3. Do not fill the tank to its maximum capacity; 4. Do not wait until the fuel warning light (yellow light) comes on to refuel; 5. The use of communication devices is prohibited.
