Should the engine be turned off and the key removed when refueling a car?

Refueling requires turning off the engine and removing the key. Reasons for turning off the engine during refueling: Gasoline is an electrolyte. If the vehicle is not turned off during the refueling process, although the car is not moving forward, the internal engine and other instruments are still in operation. Not turning off the engine during refueling may cause leakage in the operating instruments, leading to short circuits or other electrical issues. Gas station regulations during refueling: Gas stations strictly prohibit wearing, removing, or slapping synthetic fiber clothing and using mobile phones at the refueling site. Gas stations are most afraid of open flames and static electricity. Synthetic fiber clothing is prone to generating static electricity, so do not get out of the car and slap clothes during refueling to avoid the risk of static electricity igniting gasoline.
After driving for so many years, turning off the engine while refueling is an absolute must, and I strictly follow this every time. When the engine is running, the exhaust pipe reaches extremely high temperatures, and gasoline vapors are highly volatile. Even the tiniest spark could ignite a major fire—this is no joke. Removing the key is also crucial to prevent mischievous kids from pressing the start button or someone driving off with your car after refueling. Last week, the gas station even posted a new notice emphasizing that refueling is only allowed with the engine off, otherwise service will be denied. Safety is no trivial matter—forming this habit only takes an extra ten seconds, so never cut corners and risk potential hazards.
