Is it dangerous to drive away without turning off the engine while refueling?

[LaLuke]

It's not a big deal. Not turning off the engine while refueling poses risks, but once refueling is completed, there's no issue. Turn off the engine when refueling: The main risk of not turning off the engine while refueling comes from the high temperature generated by the running engine. High temperatures accelerate fuel evaporation, and during refueling, fuel vapor mixes with air to form a combustible gas, which can ignite and cause an explosion with just a spark. Do not use mobile phones while refueling: The threat of using a mobile phone while refueling lies in the electromagnetic radiation from the phone. If it encounters charged particles, it can generate sparks, igniting the fuel vapor. Although the probability of this happening is extremely low, since it's a regulation, it indicates that the danger certainly exists.
