Refueling While Engine Is Running: Safety Risks, Dos & Don’ts

When you pull up to a petrol station, you might be tempted to leave the engine running while you refuel, especially during Dubai’s hot summer months when you want to keep the air conditioning on. But while it may seem harmless, refueling with the engine running poses real safety risks that many drivers overlook. 

In this blog, Drive UAE will explain why this practice is dangerous, what you should do instead, and the essential dos and don’ts to keep you safe while refueling in the UAE.

Why You Should Never Refuel While the Engine Is Running

Leaving your engine on while pumping fuel can lead to serious accidents. Petrol vapour is highly flammable. When the engine runs, several components, such as the alternator, spark plugs, or even the exhaust system, generate heat and electrical sparks. These sparks can ignite fuel vapours that escape during refueling, leading to fire or even explosions.

Even though modern fuel pumps and vehicles are designed with safety mechanisms, the risk still exists. Here’s why experts recommend always switching off the engine before refueling:

• Static Electricity Build-Up: Static charges can develop when you exit and re-enter your car, especially in dry conditions. A small spark when you touch the nozzle can ignite fuel vapours.
  
• Ignition Risk: A running engine continuously produces heat and small sparks, increasing the chance of ignition if vapours are present.
  
• Fire Hazard: Petrol fumes are invisible but highly flammable. A single ignition source is enough to cause a fire.
  
• Legal Implications: In the UAE, petrol station safety regulations require drivers to switch off their engines before refueling. Ignoring this rule can lead to fines or penalties.
  

Simply put: even if it feels convenient, keeping your engine on during refueling isn’t worth the risk

Safety Risks of Refueling While Engine Is Running

Let’s look deeper into the specific dangers involved when you leave your engine running during refueling:

1. Explosion Risk
   Petrol vapours can accumulate near the fuel nozzle or around the car’s tank. If these vapours come in contact with engine heat or electrical sparks, they can ignite instantly.
   
2. Fire Spread
   Once a fire starts near the fuel nozzle, it can spread rapidly to the entire vehicle. This not only endangers your life but also puts nearby vehicles and petrol station staff at risk.
   
3. Fuel Spillage
   A running engine can cause minor vibrations. These vibrations sometimes make the fuel nozzle slip, leading to fuel spillage. Even small spills increase fire risk and waste fuel.
   
4. Damage to Vehicle Components
   Some vehicles have advanced emission control systems that regulate air and fuel vapour pressure. Refueling while the engine is on can confuse the sensors or damage these systems over time.
   
5. Violation of Safety Protocols
   UAE petrol stations are strict about safety compliance. Leaving the engine on can be seen as negligence, and attendants may refuse service until the car is fully turned off.
   

Dos and Don’ts When Refueling Your Car

Refueling safely doesn’t take much effort, it’s about following basic precautions. Here’s what every driver should remember:

Dos

• Always turn off the engine before opening the fuel cap.
  
• Switch off the ignition and accessories such as air conditioning, headlights, and radios.
  
• Step out of the car calmly and avoid re-entering until you finish refueling to reduce static build-up.
  
• Keep your mobile phone away while at the pump; although rare, electronic signals can interact with vapours.
  
• Follow the attendant’s instructions if you’re at a full-service station.
  
• Use only approved fuel containers if you’re refilling extra fuel.
  

Don’ts

• Don’t smoke or use open flames near fuel pumps.
  
• Don’t keep the car running to stay cool; turn off the engine and step out instead.
  
• Don’t top off the tank after the pump automatically stops, it can lead to overflow and fuel waste.
  
• Don’t leave children or pets unattended in the car while refueling, especially under the sun.
  
• Don’t rush the process, take a moment to ensure everything is safe and secure.
  

Best Practices for Safe Refueling in the UAE

The UAE has some of the most modern and well-managed petrol stations in the region, but personal safety still comes first. Here are additional practices to keep in mind:

• Choose reputable fuel stations like ADNOC, ENOC, or EPPCO that follow national safety regulations.
  
• Wait until the engine cools down if you’ve just completed a long drive.
  
• Avoid distractions, don’t use your phone or chat while refueling.
  
• Keep an eye on the fuel level to prevent overfilling or spills.
  
• Report any leaks or spills immediately to the station attendant.
  
• Make sure the fuel cap is tightly closed after refueling to prevent vapour leakage.
  

What to Do in Case of a Fire or Fuel Spill

Even with all precautions, accidents can happen. If you ever face a fire or spill while refueling, here’s what to do immediately:

1. Stop fueling right away – Release the handle and step back from the vehicle.
   
2. Move to a safe distance – Get at least 15–20 meters away from the car.
   
3. Alert station staff – They are trained to handle such emergencies and have fire extinguishers nearby.
   
4. Do not start your car – If fuel has spilled, don’t attempt to drive away until it’s cleaned properly.
   
5. Call emergency services if needed.
   

These steps can make a major difference in preventing injury or greater damage.

Legal Guidelines on Refueling Safety in the UAE

According to UAE Civil Defence regulations, petrol stations are strictly monitored to ensure compliance with fire and safety standards. All vehicles must have engines switched off during refueling, and smoking is strictly prohibited on-site. Failing to follow these rules can lead to fines and possible suspension of refueling privileges.

Moreover, attendants at UAE stations are trained to stop service if a driver ignores safety instructions. Following these rules not only keeps you safe but also respects the people working hard to maintain these facilities.

Conclusion

Refueling while the engine is running may seem convenient, but it’s never safe. The risks of fire, explosion, or equipment damage far outweigh the few minutes of comfort. Always switch off your engine, step out of the vehicle, and refuel carefully. Safety at petrol stations is everyone’s responsibility.
