The probability of a fire caused by cell phone calls is very small.
1999, the whole world believes that mobile phones can cause fires.
Looking through a lot of information, I found that there were a lot of reports about mobile phones detonating gas stations as early as 1999.
Guo Baoshan of Hebei Petroleum Group published a paper in Oil Depot and Gas Station in April 1 "Mobile phones must be prohibited in fire and explosion dangerous places". It reads: It is reported that three years ago (that is, 1996), there were 1 gas stations in Australia that exploded because customers used mobile phones.
The high-frequency radio signal sent by the mobile phone and the discharge energy of the battery are enough to cause combustion, and the use of mobile phones and walkie-talkies should be prohibited in gas stations. At that time, mobile phone manufacturers such as Motorola, Ericsson and Nokia also mentioned in the instructions: Don't use mobile phones at gas stations.
So at that time, it was generally believed that mobile phones would cause gas station explosions at home and abroad, and newspapers all over the world rushed to report them. At that time, from 65438 to 0996, gas stations all over the country successively issued regulations prohibiting the use of mobile phones.
The research shows that the probability is only 10/0.
What is the truth? Can cell phone calls really cause fires or explosions? The explosion of the Australian gas station mentioned in the previous article was specially sought.
In 2005, the Australian Transportation Safety Administration published 1 paper "Static Fires at Retail Gas Stations", which investigated 243 fires allegedly caused by mobile phones from 1993 to 2004. The previous news said explosion, but there was no explosion in the report, and the word used was fire. Actually, it's not as exaggerated as we thought
The study found that the real cause of the recorded fire had nothing to do with the mobile phone. Many times it is caused by human static electricity, not the problem of mobile phone communication. And after so many years, mainstream academic research also believes that in gas stations, cell phone signals and batteries will not cause explosions.
Professor Adam of Kent University published a paper in Health, Risk and Society, entitled "Real Risk and Illusion Risk of Gas Station: Strange Cases of Cell Phone, Fire and Static Electricity". It synthesizes the research of universities, mobile phone manufacturers and academic societies, and draws a conclusion: mobile phones may cause fires in theory, but the conditions are very harsh, which is almost impossible in reality.
What are the odds? In 20 19, Ontario Technical Standards Safety Bureau of Canada gave a data: 65438+ 1 over 100 billion. How did you work it out? This is a big number. They explained that in the past 20 years, there have been no 1 gas station fires in Canada.
Canada has 65438+ billion refueling times every year, and the probability of causing a fire is very small. So in Ontario, Canada, it is allowed to pay by mobile phone directly next to the air gun.
Although the probability is small, it should not be underestimated.
According to the regulations, we can't actually scan the code to pay in the car.
But interestingly, many countries in the world, such as Canada and Britain, still don't allow the use of mobile phones around oil guns.
Refer to Safety Code for Gas Station Operation (AQ30 10-2007) and Code for Design and Construction of Automobile Filling Stations (GB50 156-20 12). The explosion danger zone is within 3m of the tanker, and communication equipment is strictly prohibited in this zone. So the purpose of this regulation is to nip in the bud. Although it is almost impossible to happen, this probability is not 0, so it is still necessary to standardize and life is precious.
And the safety management level of each gas station is different. Unified standards, no use, easy to understand and clear. There is no ambiguity, and there is no disregard for the situation, right?
What is the correct method?
For us, the correct way to refuel at a gas station is to get off at a place 3 meters away from the oil gun and scan the code to pay, which is relatively safe. Compared with mobile phones, static electricity is the so-called "culprit" of many gas stations.
Or a paper from Kent University, which says: There are many gas station fires caused by static electricity, which are clearly recorded in Europe and America. Especially in America, a lot has happened. In 2003 alone, there were about 1 00 cases. Therefore, in fact, we should pay more attention to static electricity.
If you run to the vicinity of the oil gun and have a look, how much will it cost and how much will it cost? Isn't it just a glimpse? Or check whether the fuel tank cover is closed properly. Check your static electricity first.
How to get there? Above the gas station, you will find a round metal block on the side of the gun, which is marked "Discharge static electricity, hands". Just touch it and it's very convenient.
It's good for you, too Sometimes when you are fine at the gas station, you just sit there and say, "It doesn't matter if I don't have static electricity." Back to the office building, press the elevator button and get electrocuted. Therefore, it is better to remove static electricity when refueling.
Mobile phones are used in gas stations, and the probability of explosion is very low.
Generally speaking, using a mobile phone at a gas station, whether making a phone call or paying for it, has a very low probability of causing an explosion, which is basically unlikely to happen.
But as long as it is possible in theory, we'd better be careful, just in case. It's good to stay away from the oil gun and keep it above 3m when paying. You can get rid of static electricity.
