Like any law-abiding citizen, he stops at the gas pump, turns off his vehicle’s engine, and then begins to fill up. While in this weather, other motorists leave their car engines running. Therefore, should this practice be considered dangerous?
To dispel your doubts about this question that you all ask, do not hesitate to read the following lines.
Is it dangerous to leave your car engine running while refueling?
Probably not, in most cases. Think back to your far-off physics lessons… To create fire, the recipe traditionally comes in the form of a triangle, consisting of three elements: first, fuel; second, an oxidant (usually oxygen); and third, heat or a flammable source. Let’s take each of these factors to provide answers regarding this question.
First, the fuel. Yes, you can definitely smell the fuel (gasoline vapor) when you refuel at a gas station. But gasoline vapors usually don’t burn.. Gasoline vapor only burns when air volume concentrations are between 2 and 8 percent. When the concentration is less than 2%, there is not enough fuel to sustain a flame. And when this exceeds 8%, there isn’t enough oxygen available to combine with the gasoline vapors, so again, combustion is not possible.
The second element, the oxidizer or oxygen. Air contains approximately 20% oxygen. So when you refuel, you are completely surrounded by one of these three factors.
The third element is heat. In fact, there are several potential ignition sources present in a car.
Therefore, the starter can generate hot electrical sparks. Spark plugs ignite the fuel-air mixture inside your engine. They carry tens of thousands of volts of electricity, which are normally well insulated. Nevertheless, if the insulation on the wire breaks, it could ignite gasoline vapors. But in this case, you would have a hard time starting the engine, especially in wet weather.
In some countries, regulations state that the engine must be turned off during refueling. However, some motorists are content to ignore it. This is the case in hot weather and many drivers leave the engine running to take advantage of the air conditioning.. On the other hand, there is no regulation that prohibits running the engine of a vehicle near a driver who is refueling.
However, it is dangerous to leave the engine running with children in the car. They may be tempted to replicate the maneuvers of their parents by pressing the accelerator and changing gears.
Still, if you’re worried your car might catch fire if you leave the engine running while you refuel, you can use your common sense and turn off your vehicle’s engine.
