Mobile phones are not allowed in gas stations, so how can I pay better?

Yuan Keliang, deputy director of the Luoyang Municipal Emergency Management Bureau, who participated in the TV politics, said that there are indeed places where supervision is not in place, and a variety of measures will be taken in the future to prohibit all use of mobile phones in the refueling area of gas stations in the city

Second, set up obvious warning signs in a conspicuous position at the gas station, prompting the driver not to scan the code to pay in the refueling area, and it is strictly forbidden to use mobile phones such as dialing mobile phones, WeChat chatting and taking pictures.

Song Yubo, an associate professor at Southeast University's School of Cyberspace Security, explained that the use of mobile phones to cause gas stations to burn requires two conditions: first, the concentration of oil and gas mixture on site must reach a certain proportion, and second, the power of the electromagnetic waves of mobile phones is large enough to produce electrical sparks on the circuit.

Therefore, it is theoretically possible to make a call in a gas station or use other functions of the mobile phone to trigger oil and gas**, but in real life, the probability is very low, as long as we keep the place of payment away from the gas gun, the risk factor will be reduced.

The prohibition of using mobile phones at gas stations is to prohibit the use of mobile phones to call**, because mobile phones will increase the transmission power in order to maintain the quality of the call when calling, because static sparks are likely to be generated at high frequency and high power, mobile phone payment can be used. Cash payments are also available.

Hello, recently some places have been expertly demonstrated, mobile phone payment in the gas station is also a security risk, it is estimated that the use of mobile phone payment will no longer be allowed, in this case you need to use cash payment or card payment. Hope mine is helpful to you.

If the gas station clearly stipulates that mobile phone payment cannot be used, you can pay by card or cash, because people do not like to carry cash when traveling, you can consider using a card to pay, which is safe and convenient.

Mobile payment is available. Just can't hit **.

I don't think many people still go out with their wallets and cash these days. It's because with the advancement of our technology, more and more people are now joining the ranks of mobile payments. Mobile payment is fast and convenient, which not only saves the trouble of making change, but also saves the contact between the two parties, especially during the epidemic, which is undoubtedly a better way.

However, as far as I know, many hospitals do not allow the use of mobile payment, and gas stations do not allow mobile phone scanning code payment. Why is that? Why is it not recommended to use a mobile phone at a gas station?

Follow this article, let's go to the ** reason.

If you want to know why gas stations don't support mobile phone scanning code payment, you must first understand why gas stations prohibit the use of mobile phones. There are many gas stations in China, and it is clearly stipulated that the use of mobile phones is prohibited in the gas station area, because once the mobile phone is used, there are risks and potential safety hazards. Through some news reports, we know that if you use a mobile phone at a gas station, it may cause a spark, the main reason is that when we use mobile, electromagnetic waves will be generated, and in the gas station, if the concentration of oil and gas mixture is high, the electromagnetic wave caused by the mobile phone will produce sparks when it reaches a certain power, which will cause the mixture of gases to be generated.

Then we can understand why it is not recommended to use QR code payment. Strictly speaking, scanning code payment is also a way to use mobile phones, which will also produce a certain amount of electromagnetic waves, but compared to the first call, the power of this electromagnetic wave is relatively small, and it is usually not easy to produce electric sparks, that is, the possibility of generating ** is relatively small, but it does not rule out the situation in case. Therefore, many gas stations prohibit QR code payment for safety reasons.

If you don't have cash on your body, and you can only pay by scanning the code, you should explain to the staff that you can scan the code outside the gas station area.

This is a very normal thing, and it is also for the safety of everyone, because it is life-threatening to pay with a mobile phone scanning code, and it is very likely to happen**.

The inside of the mobile phone is some electronic components, and when the mobile phone is used, a rather weak discharge phenomenon will be generated inside, resulting in tiny electric sparks. If the proportion of gasoline gas in the air near the gas station is too high, it can also cause such an electric spark.

In the same way, if there is a gas leak at home, please do not use the ** alarm in the room. Because the moment you pick up the microphone, an electric spark can be generated inside the machine, and the gas concentration in the room is too high, which will cause.

Hazards of Disaster:

Electrostatics. 1. Analysis of the electrostatic initiation mechanism of flammable and explosive liquids.

Static electricity may be generated in the process of flowing, stirring, sedimentation, filtration, shaking, spraying, splashing, scouring, perfusion, etc., and static electricity often causes fire and ** of flammable and explosive liquids. Its initiation mechanism is based on the theory of the electric layer.

When a liquid comes into contact with a solid, two layers of charges with equal amounts and opposite signs are formed at their interface, i.e., the electric layer. The main reason for the formation of the galvanic layer is that the liquid medium can be dissociated into positive and negative ions in different ways. For example, polar molecules, liquids, or impurity molecules can be dissociated directly.

2. Analysis of the electrostatic initiation mechanism of flammable and explosive gases.

Pure gases are not charged under normal conditions. High-pressure gases are ejected with static electricity because of the presence of solid or liquid particles suspended in these gases. When the high-pressure gas is mixed with solid particles, the particles and gas flow together in the tube when the gas is ejected at high speed, and the particles and the inner wall of the tube are in frequent contact - separation process, resulting in the particles and the pipe wall respectively with the same amount of different charges.

Presumably everyone knows that you can't take calls in gas stations, which is common sense of safety, but with the popularity of scanning code payment, and in order to prevent and control the epidemic, many gas stations have launched "no contact refueling without getting off the car", drivers can complete the payment by scanning a code while sitting in the car, this payment method provides convenience to people, so is it dangerous for gas stations to pay with mobile phones?

The Haining Belt Ruji City Procuratorate inquired about the danger of using mobile phone payment at gas stations, and tested the equivalent plane wave power density (W m2) of mobile phones in four states with communication experts

1. Standby state: The equivalent plane wave power density in the standby state of the mobile phone is;

3. Scan code payment status: The equivalent plane wave power density in the mobile phone scan code payment state is;

4. Call state: The equivalent plane wave power density of the mobile phone in the call state is.

As a non-stupid parallel electrical communication tool, the radio waves emitted by the radio transmitter can make the antenna receiving the radio produce radio frequency current, if the current circulates between the metal conductors when the contact is poor and produces radio frequency sparks, then it may cause **.

Through the above tests, it is concluded that the electromagnetic radiation power of the mobile phone in the state of scanning code payment is far greater than the electromagnetic radiation power in the state of mobile phone call, so the possibility of using mobile phone scanning code payment next to the fuel dispenser is greater than that of calling. After discussion, experts concluded that there are security risks associated with mobile payments next to the tanker.

It is understood that at present, Nanjing, Luoyang, Suzhou and other regions in China have banned the use of mobile phone scanning code payment in the refueling area. Now mobile phone scan code payment has been widely used in various scenes of life, many people go out without cash, for this situation, if the car owner wants to scan the code to pay, then need to move to the gas station convenience store or office area to use the mobile phone scan code payment.

The gas station staff said that although moving to the convenience store or office area for mobile phone scanning code payment is not as convenient for customers as directly scanning the code next to the gas dispenser, but customers can understand that they must go to the service desk far away from the gas station to scan the code to pay, after all, this is related to everyone's safety, and running two more steps can avoid the situation caused by mobile phones.

Playing a cell phone at a gas station is very dangerous, although the phone does not produce a curved fire. However, when the mobile phone receives or transmits high-frequency electromagnetic waves, there will be high-frequency currents in it, and if the mobile phone has poor contact, there will be a chance to generate electric sparks.

As long as the spark lasts for 1 microsecond and the discharge energy is 6 milliwatts, it may cause gas combustion. Gasoline is a volatile substance, when the mixing ratio of gasoline and air in the environment reaches a certain standard, it may be caused by high-frequency current, static electricity and other ignitions. Therefore, even if the gas station does not post a sign prohibiting **, when we are refueling, we must consciously not pick up **.

First, smoking is strictly prohibited: the surface temperature of cigarette butts is generally 200 to 300 degrees, which is very easy to ignite gasoline, and a large number of flammable gas molecules gather near gas stations.

Second, the refueling must be turned off: during the operation of the vehicle, the gas flow of the intake and exhaust, and the subtle aging on the line, will produce static electricity and even sparks, especially in humid weather, the concentration of gasoline increases, and the probability of electric sparks igniting gasoline greatly increases.

Third, don't slap chemical fiber clothing when refueling: Clothes made of chemical fiber fabrics are very easy to generate static electricity, so don't get out of the car and pat when refueling, so as not to cause unpredictable dangers. Fourth, it is forbidden to repair cars at gas stations:

When repairing the car, the leakage of high-temperature parts of the engine or the pressure system will cause fire, especially the fault of some electrical short-circuits is more dangerous.
