Why did the gas station shut down the tanker on a thunderous day?

Thunder is a discharge phenomenon in nature. When huge natural energy is released, it will generate static electricity with the surrounding objects, which is invisible to electrostatic people. Generally gas stations are outdoors, and some oil will be exposed to the air. Static electricity is likely to cause oil burning and explosion! But now gas stations are generally closed to refuel, which means that oil will not be directly exposed to the air, and the risk is much smaller!

Oil is a flammable substance, which will ignite when it meets an open flame or electric spark. Therefore, gas stations will pick up warning signs that prohibit fireworks and mobile phones, just to prevent thunderstorm weather, especially when it thunders. Electric spark or open flame contains many charged particles in the air, so you can't refuel when it thunders, which can reduce the danger.

The gas station must be closed when it thunders.
