Have you ever pulled up to a gas station and left your car running while you pumped gas? Maybe you've even seen other drivers doing it and thought nothing of it.
However, there is a common myth circulating that suggests pumping gas while a car is running can be a dangerous practice.
In this article, we'll explore this myth, examine the facts, and ultimately determine if it's a myth or a fact.
The Myth: Gasoline Vapor Can Ignite
The myth that pumping gas while your car is running is dangerous is based on the idea that gasoline vapor can ignite from the heat generated by your car's engine.
Gasoline is a highly flammable liquid, and it's true that gasoline vapor can ignite under certain conditions.
However, the question remains: is pumping gas while your car is running in one of those conditions?
The Reality: It's Not a Good Idea
The reality is that it is possible for gasoline vapors to ignite when you're pumping gas into your car, but it's also extremely unlikely to happen.
Gasoline vapors are heavier than air, which means they tend to sink and accumulate at ground level.
Additionally, gas pumps are designed with safety features to prevent ignition, such as a vapor recovery system that captures any escaping gas fumes.
However, just because the likelihood of an accident is low doesn't mean you should ignore the risks. Gasoline vapors can still be ignited by a spark, static electricity, or even a cigarette.
Pumping gas with your car running increases the risk of a spark occurring, as your car's electrical system is generating electricity while it's running.
That's why it's not a good idea to pump gas while the car is running.
What Happens If You Pump Gas With the Car On?
The risks associated with pumping gas while your car is running include fire and explosion.
In the event of a spark igniting gasoline vapors, a fire can quickly spread, causing significant damage to your vehicle and putting you and other drivers at risk.
Even worse, if the fire ignites the gas storage tanks at the station, it can result in an explosion that can be deadly.
In 2019, a woman in New Jersey was filling up her gas tank when she accidentally ignited gasoline vapors with a lighter. She suffered severe burns and had to be hospitalized.
Similarly, in 2017, a man in Florida was pumping gas when he dropped his cigarette, igniting gasoline vapors and causing a massive explosion. He suffered severe burns and had to be hospitalized.
Is It Safe to Pump Gas While the Car is Running?
Pumping gas while your car is running is not recommended. While the risk of an accident is low, the consequences can be severe.
To reduce the risk of a fire or explosion, always turn off your car's engine when you're pumping gas.
Additionally, avoid smoking or using your cell phone while you're at the pump, as these activities can also increase the risk of a fire.
If you're worried about the safety of your vehicle, it's worth noting that modern cars are equipped with various safety features that can help prevent accidents.
For example, many cars have an automatic shut-off feature that stops the flow of gas once the tank is full. Additionally, some cars have a low-fuel warning light that alerts drivers when it's time to refuel.
Tips for Pumping Gas Safely
If you want to pump gas while the car is running, here are some tips to do so safely:
- Avoid pumping gas in enclosed spaces, such as garages or parking garages, where gasoline fumes could accumulate.
- If you can smell gasoline fumes or suspect a gas leak, turn off the engine and get help immediately.
- Make sure your car is in the park and the emergency brake is on before you start pumping gas.
- Avoid smoking or using electronic devices, such as cell phones, while pumping gas, as they could ignite gasoline vapors.
- Avoid overfilling your gas tank, as this can cause gasoline to spill onto the ground, creating a fire hazard.
- You should also be careful when handling the gas pump nozzle, making sure not to let it touch your car or other objects that could create a spark.
- Follow any additional safety instructions provided by the gas station, such as not re-entering the vehicle while fueling.
Final Thoughts
In conclusion, the myth that pumping gas while your car is running is dangerous is based on some truth, but the risks associated with this practice are relatively low.
However, just because the likelihood of an accident is low doesn't mean you should ignore the risks.
To ensure your safety and the safety of those around you, it's important to always turn off your car's engine when pumping gas.
In addition to turning off your engine, there are other precautions you can take to reduce the risk of a fire or explosion at the pump.
It's also worth noting that some states have laws prohibiting the practice of pumping gas with your car running.
For example, in New Jersey, it is illegal to pump your own gas, and attendants are required to turn off the car's engine before pumping gas.
