What are the dangers of refueling without turning off the engine?
2 Answers
The hazards of refueling without turning off the engine: 1. When opening the fuel tank cap, fuel may spray out, creating a safety hazard; 2. The engine continues to run with current flowing, which can lead to short circuits or leakage, posing a significant fire risk; 3. The surrounding area of the car generates considerable heat. During refueling, the concentration of fuel vapor mixed with air around the tank increases. If a spark occurs while the vehicle is running, the gasoline molecules in the air can easily ignite, leading to danger. Precautions for refueling: 1. Do not use mobile phones; 2. No smoking; 3. Turn off the engine and power supply before refueling.
Having driven for so many years, I'm well aware of the extreme dangers of refueling without turning off the engine. The most immediate risk is fire and explosion. When the engine is still running, the temperature in the exhaust pipe and engine compartment is terrifyingly high, and gasoline is a highly flammable and explosive liquid. Even a slight vapor leak or spill coming into contact with a heat source can trigger a major fire. This not only endangers your own life but could also burn people and vehicles nearby—the scenario is truly horrifying. I've seen some friends carelessly do this, resulting in severe vehicle damage and astronomically high repair costs. Secondly, safety hazards also include sudden vehicle movement. If the driver forgets to shift to neutral or step on the brake, the car might lurch forward during refueling, hitting the fuel pump or people, causing accidents. Environmentally, keeping the engine running also increases exhaust emissions, polluting the air. Every time I go to the gas station, I consciously turn off the engine—this not only protects myself and others but also complies with safety regulations. Developing this simple habit can prevent unnecessary trouble.
