Why not play mobile phone at the gas station?

In addition to the warning signs of "no fireworks", gas stations often see related slogans of "no use of mobile phones". For the former, we can strictly abide by it, but for the latter, we find that many people take an indifferent attitude, and the phenomenon of using mobile phones in gas stations is still very common, especially for some passengers who come into the station with the car, there are more women than men.

When employees at gas stations are not busy at work, they see some thugs coming forward to dissuade them, but when they are busy, they have no time to take care of these things. And sometimes even if the staff come forward to discourage, many people don't understand it very well, and disputes often occur, and some people say they don't know; There are still quite a few people who tend to be impatient or even rude; Some people simply turn a deaf ear.

To be honest, although I haven't made a cell phone call at the gas station, I don't quite understand why the gas station can't make a cell phone call. I hope your magazine can give an answer.

The editorial department replied:

In view of the above problems, the editorial department specially invited Fan Miao of China Petroleum Liaoning Sales Fushun Branch to answer your questions.

As we all know, gas stations dealing in inflammable and explosive articles belong to high-risk industries, and "safety first" is the most basic requirement for gas stations. Common safety measures in gas stations mainly include stopping motorcycles to refuel, employees in gas stations must wear anti-static clothes, and it is forbidden to use naked flames and mobile phones in gas stations, and it is forbidden to refuel in plastic barrels. One of the most difficult things to manage is to prohibit customers from using mobile phones at gas stations.

Root evidence

First of all, people have misunderstandings about the security risks caused by using mobile phones in gas stations. Some people think that the explosion of gas stations is alarmist, and they have never heard of the explosion caused by mobile phones. In fact, there is a certain scientific basis for the explosion caused by mobile phones.

As a radio communication tool, mobile phone can induce RF current through radio waves (RF electromagnetic radiation) emitted by radio transmitter. When RF current circulates between metal conductors, if corrosion or poor contact occurs, RF sparks will occur. As long as the duration of RF spark exceeds 1 microsecond and the energy exceeds 6 MW, the mixture of methane and air will be ignited. Because gasoline is a volatile substance, in the flammable gas danger zone formed by the leakage of oil and gas tanks and natural gas pipelines, the radio frequency sparks generated by mobile phones can easily lead to explosions and disasters.

When a gas station injects gasoline into the fuel tank of a car or motorcycle through an oil gun, the oil and gas in the original empty fuel tank drifts outward, and the newly injected gasoline also volatilizes into the air, so that the oil and gas density around the refueling vehicle suddenly increases. At the same time, in order to make communication signals clearer, people use mobile phones with high frequency and high transmission power, which still pose a serious threat to gas filling stations, although they meet the national standards. Because computer control is widely used in refueling stations now, high-intensity mobile phone signals will be induced by computer equipment, and the instantaneous electronic friction between them may ignite fuel vapor and cause an explosion. The current required to ignite the gas is very small, and the electrostatic current generated by the mobile phone in the working state can completely reach this limit. If you encounter cloudy or foggy weather with high air humidity and low air pressure when picking up and unloading oil products at refueling and filling stations, the density of oil and gas will increase accordingly due to poor air circulation, and the possibility of explosion caused by picking up mobile phones will further increase.

In addition, because the mobile phone itself does not have explosion-proof function, if the mobile phone is used for a long time or the quality of the mobile phone itself is poor, the circuit of the internal chip of the mobile phone is easy to short-circuit, which will cause a small amount of sparks when the mobile phone is answered, and will also cause the gas station to explode.

Secondly, the way to prohibit customers from using mobile phones at gas stations is relatively simple. At present, the main way for gas stations to prohibit customers from using mobile phones at gas stations is persuasion, but sometimes the effect of persuasion is not ideal. On the one hand, customers are not clear about the safety management regulations of gas stations, and think that it is unnecessary for gas station employees not to use mobile phones at gas stations, which is easy to produce rebellious psychology. On the other hand, customers know that they can't use mobile phones at gas stations, but they are lucky. They unilaterally think that using mobile phones will be fine, so they don't listen to the persuasion of gas station employees and go their own way.

Leader "

There is a customer talking on his cell phone in the gas station. What should I do? Judging from the current situation, the author thinks that the following measures should be taken: First, publicize the dangers of using mobile phones in gas stations through newspapers, radio and printed leaflets, so as to let customers know that it is unsafe to use mobile phones in gas stations. The second is to strengthen employees' safety awareness and sense of responsibility. For customers who use mobile phones at gas stations, we should do everything possible to stop them, and actively and patiently do a good job of explaining them to win their understanding and support. Third, the use of mobile phone signal shields and other equipment, resulting in the gas station area can not normally use mobile phones to talk.

It is not uncommon for customers to use mobile phones at gas stations. Gas stations should be prepared for danger in times of peace, but they should be prepared for danger. We can't turn a blind eye to this phenomenon. We should take effective measures to eliminate potential safety hazards and ensure the safety of gas stations.
