First of all, what is gasoline? So no, it’s not a decomposing dinosaur as I already explained to you in a previous episode on the subject. Gasoline is a liquidliquid flammable which comes from the distillationdistillation of oiloil. It is used as fuel for so-called “high-speed” engines. combustioncombustion internal “. We are talking here about planes, boats or even carscars. Not all cars, but those that use spark ignition engine fuel. To put it simply: I am distinguishing here between cars that have a gasoline engine and those that have a diesel engine. It’s important not to confuse the two when you’re at the gas pump, otherwise you risk causing your car’s engine to explode, which is not very practical for driving it. And then there are the hybrid carshybrid cars and those that run 100% on electricity. But anyway, we’re getting away from the subject. Coming back to the essence, it is a mixture ofhydrocarbonshydrocarbons to which additives have been added. Today we have many types of essences which are manufactured according to several recipes, and which are put on the market, so that everyone can find what they want.
Watch out for sparks!
When we talk about “refueling”, it therefore amounts to transferring a flammable liquid from one tank to another. And that releases explosive vapors. A single spark, just one tiny mini-spark, coupled with obvious bad luck, could be enough to blow up the entire gas station. It’s scary, isn’t it? Especially since this kind ofaccidentaccident happens more often than you think. We still have around twenty fires declared around the world each year because of this, so it’s not a myth. But could a cell phone really be the cause of one of these departures? feufeu ? Some say that a simple telephone can ignite the gasoline vapor that escapes from the nozzle used to refuel. A 100% charged phone battery would carry within it several million times theenergyenergy necessary for the production of a spark, which, we recall, could cause everything to blow up. It really wouldn’t be fun, it would even be super dangerous. If the battery is malfunctioning, if it is damaged, in theory, it could produce a spark and then, boom! So. Except that, well, that’s in theory.
In practice, there has never been an explosion caused by the use of a telephone near a gas station. So in idea, yes, there is a risk, but it is almost zero, therefore negligible. Well, all the same, it’s a bit scary given the damage it could cause, so let’s stay careful. Especially since if you ever drop your smartphone, it could come into contact with gasoline and, on the one hand, it risks becoming unusable, because its electronic components are not very friendly with gasoline, but in more than two, there is always this risk of a spark. But that won’t happen if we stay careful!
The other problem with using our phone is that we tend to focus exclusively on it, which could cause us to do something stupid with the gas pump. And honestly, given the consequences there may be, maybe now is not the time to clown around with this flammable liquid. Yes, it’s you I’m looking at too, all of you who have already left with the pump still attached to your car. For all these reasons, in some parts of the world, the use of cell phones is even prohibited at the station, and you can receive a fine or have points taken off your license if you are caught in the act!
So, a few reminders and tips for refueling safely. First of all, never forget to turn off your vehicle. Same thing, you could cause a fire. Likewise, no smoking or taking out electronic devices. Because yes, we talked about the cell phone because it is the most logical, but a computer is the same thing. Finally, two final tips: be careful not to overfill the tank, and especially not with gasoline that is not suitable for your car! Otherwise… There you go, I think we’ve covered it, I won’t keep you any longer, because gas pumps are really not the best place to discuss, but at least now you will know everything on the precautions to take!
