Why is smartphone use prohibited while refueling? "Why did you ask the oil company?"

[Related article] Is there a merit to sticking to gasoline brands such as "Shell" and "Eneos"?

1) There is a risk of ignition due to electromagnetic waves and static electricity emitted by mobile phones.

2) Because the radio waves of mobile phones adversely affect the gauges of refueling aircraft (same as during takeoff and landing of an airplane)

3) Talking on the phone and operating the screen will distract attention and lead to spills etc.

On the other hand, there is also the opinion that it is just an urban legend and there is no problem at all... So what is the actual situation? When I looked it up, I found that on the website of a certain gas station, the following "prohibited matters" were written in the section "How to use selfies". Click here for images

・Smoking is not allowed inside the self-service station.

・Be sure to stop the engine while refueling.

・Gasoline injection into the container is prohibited.

・Fire is strictly prohibited in the self-station.

・Using a mobile phone while refueling is prohibited.

　It is clearly written. So, this time, I asked Cosmo Oil about the reason. The answer was the above "because there is a risk of ignition due to electromagnetic waves and static electricity emitted by mobile phones."

In other words, "the electromagnetic waves and static electricity emitted by mobile phones cannot be said to be completely free of the risk of ignition". In addition, he also cited that "use of a mobile phone while refueling will distract attention by talking and operating the screen, which will lead to bloating etc." Click here for images

　By the way, there is basically no problem with the impact on instruments. Is there a case where you pay with "Osaifu-Keitai" etc? I don't think so, but he said, "Please refrain from 'refueling'." Incidentally, even at full-service gas stations where staff refuel, not self-service, Cosmo Oil told us to refrain from using mobile phones while refueling. Click here for images

Regarding "There is a risk of ignition due to electromagnetic waves and static electricity emitted by mobile phones," it has not been confirmed whether a mobile phone could actually cause a fire accident, but it should be considered just in case. sea ​​bream.

And about "calling on the phone and operating the screen will distract your attention and lead to spills, etc." is a legitimate concern, so at least while refueling, I concentrated on the refueling operation. It would be better
