Fossil fuels, including coal, oil, and natural gas, are the primary sources of energy worldwide. When burned, these fuels release carbon dioxide, a greenhouse gas that traps heat in the atmosphere, leading to global warming. The burning of fossil fuels has resulted in rising carbon emissions, with oil contributing a third of the world's carbon emissions and coal responsible for over 0.3°C of the 1°C increase in global temperatures. Natural gas, while promoted as a cleaner alternative, is still a fossil fuel, accounting for a fifth of global carbon emissions. The continued rise in emissions from fossil fuels is impeding efforts to limit global warming, highlighting the need for alternative energy sources and reduced dependence on fossil fuels.

It is safer to turn off your car while fuelling to avoid a fire
While it is technically possible to refuel a car with its engine running, it is not recommended. For safety reasons, it is always best to turn off your car engine while refueling at the pump. Gasoline vapors can escape from the tank and, if the car is on, these vapors can come into contact with static electricity, which can ignite a fire and lead to an explosion. Although the risk of a large fire is relatively small, gas stations are public places with other people and cars around that you could put at risk.
It is also important to avoid using any electrical accessories, such as the rear defroster, phone chargers, or cigarette lighters, while refueling, as these could also cause a spark and increase the risk of fire. If you smell gas during refueling, stop the process immediately and do not continue until the issue has been addressed by an attendant.
Carbon canisters are devices that can help to reduce the risk of gas station fires by trapping vapors until the engine is running, at which point they are sucked into the engine and used as fuel.
Finally, if you leave your car running while refueling, there is a risk that someone could accidentally engage the drive gear and move the car with the fueling nozzle still in the tank. Therefore, it is safer to turn off your car while refueling to avoid the risk of fire and other potential accidents.

Static electricity from your phone can increase the risk of a fire
Static electricity is a well-known cause of fires at gas stations. When a person re-enters a vehicle and slides across the seat, they can acquire a static charge of thousands of volts due to the friction between their clothing and the car seat. This static charge can then be discharged at the nozzle, igniting the gasoline vapors and causing a flash fire.
While it is true that static electricity can cause fires at gas stations, there is no evidence that cell phones have ever caused such fires. The UK Petroleum Industry Association and Brian Madderson of the Petrol Retailers Association have both stated that cell phones pose a negligible ignition risk. Dr. Stepan Lucyszyn, an electrical engineering specialist, explained that a phone battery is unlikely to generate a spark with enough energy to ignite fuel vapors.
However, it is important to note that mobile phones can be a distraction at gas stations, which are busy and dangerous places. Phil Thomas, a trading standards officer, warned about the risk of dropping a phone, which could cause a spark and ignite fuel vapors.
To stay safe at the gas pump, it is recommended to follow these guidelines:
- Stay near your vehicle's fueling point when using a self-serve station.
- Do not go back into your vehicle when refueling, as this can create a static charge.
- If you must re-enter your vehicle, discharge any static electricity by touching a metal part of the outside of your car away from the filling point before touching and removing the gas nozzle.
- Always turn off your engine, headlights, and ignition before refueling.
- Never smoke, light matches, or use a lighter while refueling.
- Do not overfill or top off your gas tank to avoid spills.
- Do not use your phone while refueling to avoid distractions and the risk of dropping it.
By following these safety guidelines, you can help reduce the risk of a fire caused by static electricity or other ignition sources at the gas station.

Faulty spark plugs can cause unburnt fuel to enter the converter and overheat
Spark plugs have one of the most important jobs in a vehicle: to provide the spark that powers the engine. They don't wear out very quickly, but their lifespan can vary depending on the type of plug and your driving habits. Typically, spark plugs last around 80,000 miles before they need replacing. However, faulty or worn spark plugs can lead to a range of issues that can cause long-term damage to your engine.
One of the most common symptoms of bad spark plugs is engine misfires. If a spark plug isn't firing correctly, the engine's combustion process is disrupted, causing the engine to stutter or jerk, especially during acceleration. This can lead to poor engine performance and increased fuel consumption, causing you to make more trips to the gas station.
If left unchecked, faulty spark plugs can cause unburnt fuel to enter the catalytic converter, leading to fouling and overheating. This can result in serious and costly catalytic converter damage. The catalytic converter is the engine's exhaust cleaner, and spark plugs that are not firing correctly can put undue stress on it.
To prevent this issue, it's important to ensure that your spark plugs are the correct type and are installed properly. Spark plugs with the appropriate type of internal resistor must be selected to maximize engine efficiency and power. Regular maintenance and inspections can help identify spark plug issues early on and prevent more serious problems down the line.

Gasoline vapours can escape and trigger the check engine light
It is not recommended to leave the engine running while refuelling your vehicle. This is primarily because of the risk of fire, however, it can also cause the check engine light to turn on.
The check engine light can be triggered by a variety of issues, one of which is gasoline vapour escaping from the fuel tank. When you open the gas tank to fill it up, you are opening a normally sealed container, and this allows vapours to escape. The vehicle's computer detects this vapour leak and triggers the check engine light.
The EVAP system is designed to capture fuel tank vapours and prevent them from escaping into the atmosphere. A properly functioning EVAP system will recirculate gasoline vapours and keep them contained. However, if there is a leak in the EVAP system, vapours can escape, leading to the check engine light turning on.
A loose or faulty fuel cap can also result in unintended emissions and trigger the check engine light. The fuel cap is part of the EVAP system and helps to prevent vapours from escaping the fuel tank. A loose cap can affect the vehicle's emission control systems and cause a check engine light to turn on.
In addition to the risk of fire and the potential for triggering the check engine light, leaving the engine running while refuelling can also waste gas due to the car idling. It is recommended to shut off the engine and unplug any charging devices before refuelling to ensure safety and avoid potential issues.

Smoking near the pump is dangerous and prohibited by the International Fire Code
It is important to exercise caution when fuelling your car to prevent accidents and potential fires. One crucial safety measure is to refrain from smoking near the pump. Smoking near the pump is not only dangerous but is also prohibited by the International Fire Code.
The act of smoking near gas pumps poses a significant fire hazard due to the presence of flammable gasoline vapours. These vapours can easily ignite if exposed to an ignition source, such as a lit cigarette or even a spark caused by static electricity. The consequences of such an ignition could be catastrophic, leading to explosions and putting the smoker, attendants, and other customers at severe risk of injury or even death.
To mitigate this risk, it is imperative to adhere to the International Fire Code, which explicitly prohibits smoking at gas stations while pumping gas. This prohibition is enforced through the display of warning signs at the pumps, and non-compliance can result in legal consequences. If individuals notice someone smoking near the pumps, they should immediately notify the station attendant or manager, who is responsible for taking appropriate action to ensure the safety of everyone on the premises.
In addition to smoking, other activities that can generate static electricity, such as using a cell phone or vaping, should be avoided while pumping gas. By following these precautions and being vigilant about our actions, we can significantly reduce the chances of a fire or explosion occurring during fuelling. It is crucial to prioritize safety and comply with the International Fire Code to protect ourselves and those around us from potential harm.
While the primary focus is on the dangers of smoking near the pump, it is also worth noting that running your car engine while refueling is not advisable. Although the chances of a fire may be minimal, leaving the engine running increases the risk of gasoline vapour ignition. Turning off your vehicle is a simple yet effective precaution to ensure a safer fuelling process.
