What are the consequences of forgetting to turn off the engine when refueling a car?

[LaMargaret]

Forgetting to turn off the engine when refueling a car can have the following consequences: 1. The vehicle's engine is running at high speed, and friction can easily generate static electricity. A short circuit to ground can ignite flammable gases, leading to rapid combustion; 2. The exhaust pipe of an idling car can reach temperatures of several hundred degrees Celsius. If gasoline drips during refueling and encounters this high temperature, it can quickly evaporate and reach the ignition point, causing a fire; 3. If the engine is not turned off, the fuel pump continues to operate, generating a large number of bubbles in the fuel tank. As the fuel level rises, flammable gases can overflow. During refueling, it is prohibited to make phone calls or smoke. In winter, avoid wearing clothes made of synthetic fibers, nylon, or knitted materials, as they can generate static electricity. Do not use plastic containers to hold gasoline or diesel, as sparks generated upon impact can ignite the fuel tank, effectively turning it into a bomb.
