Using your phone while fuelling your car has long been thought to be a possible cause of gas-station fires. However, there is no evidence to support this claim. The Federal Communications Commission (FCC) states that while it is theoretically possible for a spark from a cell phone battery to ignite gas vapour, the potential threat is minimal. The primary reason you shouldn't use your phone at the pump is that it is a major distraction. Driving off with the gas pump still in your car because you were checking your email can be extremely dangerous.

What You'll Learn

Cell phones can cause gas-station fires
It is a widely held belief that cell phones can cause gas-station fires. Gas pumps around the world bear stickers cautioning motorists to turn off their phones while refueling. This belief has led to laws and company policies banning the use of cell phones at gas stations.
However, there is conflicting evidence regarding the role of cell phones in causing gas-station fires. While some incidents have been attributed to cell phones igniting gas fumes, experts and experiments have cast doubt on this theory. They suggest that static electricity, not cell phones, may be the culprit in these fires.
Despite the conflicting evidence, it is important to take precautions when handling flammable materials such as gasoline. Following the posted rules and guidelines at gas stations can help reduce the risk of fires, regardless of the source of ignition.
To ensure safety, it is generally recommended to turn off your cell phone and avoid using it while refueling your vehicle.

Distraction is dangerous
In addition, while cell phones themselves are unlikely to generate a spark that could ignite fuel vapors, the car battery could. Some experts have found charges of up to 60,000 volts on people who get in and out of their cars while refueling, which could potentially ignite gasoline fumes.
Furthermore, the act of refueling a car requires careful attention to avoid issues with the pump. By using your phone, you may become distracted and accidentally overfill your tank, spill fuel, or forget to replace the gas cap. These mistakes can be costly and dangerous, and it's always better to be cautious when handling flammable materials like gasoline.
To ensure safety, it's best to leave your phone in the car and focus on the task of refueling. This allows you to be fully present and aware of your surroundings, reducing the risk of accidents or mishaps caused by distractions. Remember, the few minutes it takes to refuel your car are a small price to pay for your safety and the safety of those around you.

Static electricity is a risk
The risk of static electricity is heightened when individuals get in and out of their cars while refuelling. This movement can create a static charge of up to 60,000 volts, which is more than enough to ignite gasoline fumes. Therefore, it is recommended to leave your phone inside your car and focus on the task of refuelling to minimise the risk of static electricity causing a fire.
Additionally, the phone can be a distraction, and it is crucial to pay attention when handling flammable materials like gasoline. By staying alert, you can respond to any issues with the pump and be aware of your surroundings, including moving cars.
While there has been no documented case of a phone causing a fire at a gas station, the potential risk of static electricity igniting gas vapours remains a valid concern. Therefore, it is always better to be cautious and avoid using your phone while fuelling your car.

Sparks can ignite fuel vapour
While the likelihood of sparks from your phone igniting fuel vapour is slim, it is still a possibility. This is because sparks can ignite fuel vapour, and your phone can produce sparks.
Sparks are tiny bursts of electricity that can occur when there is a sudden discharge of electrical energy. This can happen when a circuit is interrupted or when two objects with a voltage difference come into contact. In the case of your phone, the circuit is the path that electricity travels through the device, and the voltage difference can occur when the phone is connected to a power source, such as a charger.
Fuel vapour, on the other hand, is a mixture of volatile organic compounds (VOCs) that evaporate from gasoline or diesel fuel. These vapours are highly flammable and can be easily ignited by a spark. Once ignited, the vapours can cause a fire or explosion, depending on the concentration of the vapours and the size of the spark.
To prevent sparks from igniting fuel vapour, it is important to keep all sources of electricity away from the fuel source. This includes not using your phone while fueling your car, as the phone could produce a spark that could ignite the fuel vapour. It is also important to ensure that the fuel tank is properly sealed and that there are no sources of ignition nearby.
While the chances of your phone producing a spark that ignites fuel vapour may be slim, it is always better to be safe than sorry when dealing with flammable materials. So, the next time you're fueling up, it's best to keep your phone in your pocket and focus on the task at hand.

You could drop your phone
While it is unlikely that using your phone while fuelling your car will cause an explosion, it is still not advisable to do so. One of the main reasons for this is that you could drop your phone.
Firstly, consider the potential damage to your phone. Dropping your phone on a hard surface, such as the floor of a gas station, could result in a cracked screen or other damage that may impair its functionality. Given the cost of repairing or replacing a phone, this is an outcome that most people would want to avoid.
Secondly, a dropped phone could cause a distraction. If you are in the middle of an important call or are waiting for a much-anticipated text, you may be tempted to try and retrieve your phone immediately. This could result in you not paying full attention to the task at hand, which could lead to spills or other accidents. As a gas station is a busy and dangerous place, it is important to remain focused and aware of your surroundings at all times.
Additionally, if your phone is dropped in an area where fuel is present, it could become contaminated. This could potentially impact the performance of your phone and may even pose a safety risk if the fuel comes into contact with the phone's battery.
Finally, it is worth considering the potential impact on others. If you drop your phone and block a busy fuel pump, you could cause delays for other customers. This could lead to frustration and even confrontations with other drivers who are in a hurry.
In conclusion, while the chances of causing an explosion by using your phone at a gas station are extremely low, the potential consequences of dropping your phone are significant. It is therefore advisable to leave your phone in your car or pocket while fuelling up to avoid any unnecessary risks or distractions.
