Do you know why the gas station disables the phone?

1, the phone used in the petrol station, will produce a fire phenomenon
In the use of mobile phones will find this phenomenon, when the phone calls, the surrounding electrical interference is relatively large, such as the radio instantaneous noise, TV screen interference, etc., the main reason is the phone calls or phone calls, around the phone The main line, such as the antenna, circuit boards, panels, etc., will produce induced electromotive force, the electromagnetic field is the strongest, and the magnetic field is the strongest, the conductor in the magnetic field, the storage tank calibration methods includes: shell, cable, circuit board, internal line, Especially the components on the phone, the resulting induced electromotive force is the strongest induction electromotive force will produce the induced current, if the phone antenna is not connected, the phone inside the circuit board contact is not good, the battery contacts are likely to produce loose phenomenon At the same time, in the mobile phone signal electromagnetic field items will also produce static accumulation, static electricity is also the main cause of the phenomenon of ignition.
2, the gas station can form explosive gas
Gas station is a special place, likely to cause gasoline, natural gas and other explosive gas leakage, especially in the process of refueling oil and gas generated in the air, especially in summer, high temperature, gasoline volatilization, resulting in high concentration of oil and gas stations Gasoline is the most dangerous in liquid fuels. Gasoline is a mixture of hydrocarbons containing 5 to 12 carbon atoms, lighter than water and insoluble in water, volatile at room temperature, temperature probe calibration than air, so easy to accumulate In the low-lying, with the air to form an explosive mixture, the explosion limit of 1.3% to 6%, petrol steam minimum ignition energy is only 0.2 mJ, so any small sparks or naked eye can not see the static electricity will lead to space gas explosion combustion.
Mobile phone in the call or in the process of mobile phone switch, the internal will produce sparks. Oil and gas diffusion when all-pervasive, once into the phone, you may encounter a spark, and this spark is enough to ignite the explosion within the limits of explosive gas Fire accident occurred.
3, the mobile phone signal electromagnetic field will affect the fuel system computer motherboard work stability
Mobile phone in the call, a strong mobile phone signal electromagnetic field will be connected with the portable fuel transfer pump in the power supply lines, communication lines on the induced electromotive force, that is, the formation of interference pulses, interference pulse into the tanker and control machine, will affect the refueling equipment computer Motherboard work stability, which will cause the program is not running properly, crash, data loss, parameter changes, measurement is not accurate and some difficult problems.
