Can I play with my mobile phone when the car is filling up at the gas station?

There are many gasoline molecules mixed in the air molecules of gas stations. Because of the characteristics of gasoline, gasoline molecules volatilized into the air will be closely combined with air molecules, and they will burn when they meet sparks, which will lead to more gasoline molecules "restlessness". The explosion accident is not far away. If you think about the worse consequences, it will be big news to ignite a huge underground oil depot. Therefore, it is common sense that everyone must ban open flames at gas stations.

After entering the gas station, it is forbidden to use lighters, matches and other items, and before refueling, the car is required to turn off the engine, because in addition to naked eye observation, the circuit in the car will also emit small sparks when starting, which is also one of the safety hazards.
