1. No fireworks sign. Obviously, gas stations and other places where flammable and explosive oil products are stored must have signs prohibiting fireworks. Automobile and diesel oil are inflammable and explosive dangerous chemicals. Even a little spark can cause fires and serious accidents.
2. No call sign. Gasoline is a volatile substance, and its molecular density in the air will be relatively high. It is quite dangerous to use mobile phones in places like gas stations. Because the mobile phone may generate RF current with the antenna while receiving radio waves, it may generate sparks at the moment of turning on the phone, which may combine with gasoline molecules in the air, causing fires and explosions.
3. Refueling and flameout sign. When the car refuels without turning off the engine, the engine and motor will keep running. In the process of operation, the possible sparks will combine with gasoline molecules volatilized in the air to explode. That's why if your car doesn't stall when you go to refuel, the staff at the gas station will remind you of the reason.
4. No smoking. Needless to say, flammable and explosive gasoline and diesel oil can cause fires when they meet sparks, not to mention smoking.
5. Escape signs. It is precisely because of the danger of storing flammable and explosive grease in automobile gas stations and the serious consequences after the accident that there will be clear escape signs in the gas station area to remind you how to escape quickly in the event of an accident.
The key areas of fire safety prevention and control in gas stations are just the main safety signs, and there are other safety signs, so I won't list them one by one. In any case, when we go to refuel, we all need to obey the command of the staff at the gas station, actively cooperate with the work of the oilers, and always keep in mind safety to prevent accidents.
