What Are the Hazards of Refueling with the Engine Running?

[DelilahRose]

The hazards of refueling with the engine running include: 1. When opening the fuel tank cap, fuel may spray out, creating a safety hazard; 2. The engine continues to operate, and with electric current flowing, short circuits or leakage may occur, easily leading to fire accidents; 3. The surrounding heat of the vehicle is relatively high, and during refueling, the concentration of fuel vapor-air mixture around the fuel tank increases accordingly. If sparks occur during vehicle operation, gasoline molecules in the air can easily ignite, posing a danger. Precautions for refueling are: 1. Refuel in the morning or evening to avoid direct sunlight at noon; 2. Add more fresh fuel before long trips; 3. Do not exceed the upper limit of the fuel tank; 4. Avoid using electronic devices; 5. No smoking; 6. Park the vehicle, turn off the engine, and shut off the power.
