What Are the Hazards of Refueling with the Engine Running?
3 Answers
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.
I've dealt with similar incidents before, and it's truly dangerous to leave the engine running while refueling. The biggest hazard is the potential for fire or even explosion, as a running engine can produce sparks or heat. If gasoline vapors come into contact with these sparks, ignition can happen instantly. Static electricity is another issue—when a person carrying static charge touches the fuel tank, it can discharge and cause a major fire. Additionally, gasoline can easily spill or leak, especially when the vehicle is shaking, which increases safety risks. Near gas stations, this behavior could trigger a chain reaction, endangering other vehicles and people. I always remind my friends that turning off the engine while refueling not only avoids these risks but also saves fuel and reduces emissions. After all, safety is no small matter—forming this habit takes just minutes but can protect your entire family's well-being.
I remember seeing my neighbor uncle make this mistake at the gas station when I was young. His truck engine was running, and a small static electricity spark nearly caused a fire while refueling. Smoke billowed out, scaring everyone away. Besides the potential explosion, keeping the engine running also wastes gasoline and increases air pollution. Gasoline vapors evaporate quickly and are harmful to inhale. Every time I go to the gas station, I turn off the engine first before getting out of the car and check if the surroundings are safe. Making a habit of such small things can prevent major troubles and also teach children about safety. Over time, you realize this is not just about protecting yourself, but also respecting other drivers.
