From April 1, 2023, the new standard AQ 3010-2022 "Safety Code for Gas Station Operations" will be implemented, replacing the original AQ 3010-2007.

The fixed combustible gas detector is usually equipped with two lower limit alarm points (the specific value is related to the model of the alarm host): "10% LEL" is the first level alarm, and "25% LEL" is the second level alarm. The portable gas detector is usually equipped with a lower limit alarm point of 25% LEL and a upper limit alarm point of 50% LEL.

As a radio communication tool, mobile phone can induce radio frequency current in the antenna receiving radio through radio waves (radio frequency electromagnetic radiation) transmitted by radio transmitter. When RF current circulates between metal conductors, RF sparks will be generated if corrosion or poor contact occurs. As long as the duration of the radio frequency spark exceeds 1 microsecond and the energy is greater than 6 milliwatts, the mixture of methane and air gas will be ignited. Because gasoline is a volatile substance, radio frequency sparks generated by mobile phones can easily cause explosions and disasters in the flammable hazardous areas caused by the leakage of oil and gas tanks and natural gas pipelines.
