Gasoline fires are among the most dangerous and unpredictable types of fires you can encounter at home. A small spill during a routine task like refueling your lawn mower or car can quickly escalate into a life-threatening emergency. With gasoline igniting at low temperatures and spreading rapidly, knowing the right steps and tools to deal with such fires can make all the difference between safely containing the situation and putting lives and property at risk.
This article will walk you through the exact actions to take if a gasoline fire occurs, including immediate safety measures, the proper tools to extinguish the fire, and essential preventative steps to avoid these incidents in the first place. Whether in your backyard or driveway, being prepared could save lives.
Understanding Gasoline Fires
Before jumping into how to respond to a gasoline fire, it’s essential to understand why gasoline fires are so dangerous and require specific responses compared to other fire types.
What Makes Gasoline Fires Unique?
- Low Ignition Temperature
Gasoline is highly volatile, which means it can ignite even at relatively low temperatures. A single spark or static discharge is enough to set it ablaze.
- Rapid Spread
Gasoline spreads quickly over surfaces, and its vapors are flammable, leading to flash fires that can cover large areas almost instantly.
- Water is Ineffective
Unlike some other fires, throwing water on a gasoline fire can make things worse. Water doesn’t mix with gasoline (due to density) and instead spreads the fuel further, intensifying the flames.
Common Scenarios That Cause Gasoline Fires
Here are a few situations where gasoline fires might be triggered at home:
- Spills During Refueling
Dripping gasoline from cars, motorbikes, or lawn equipment while refueling can result in a dangerous splash fire, especially if there’s a heat source nearby.
- Improper Storage
Leaving gasoline in unapproved containers or near ignition sources—like heaters, power tools, or cigarettes—can create a highly combustible environment.
- Lack of Cleanup After Spills
Residual gasoline left on the ground or on cleaning materials, like rags, emits vapors that could ignite from nearby flames or even a spark.
Understanding these causes is key to acting quickly and avoiding mistakes when dealing with a fire involving gasoline.
Immediate Actions to Take
Stay Calm But Act Fast
Panic can lead to rash mistakes. Keep a clear head to assess the fire properly and choose the safest course of action.
Evaluate the Situation
- Small, Containable Fire: If it’s a minor fire that you feel confident handling (e.g., a fire contained to a small spill), you should act quickly with the right extinguishing method.
- Larger Fire: If the fire spreads rapidly or feels out of control, call 911 immediately and evacuate the area.
Ensure Everyone is Safe
Move all people and pets to a safe distance—preferably well outside the immediate area. Gasoline fires not only emit heat but also release harmful chemicals into the air.
How to Put Out a Small Gasoline Fire
Step 1: Grab the Right Fire Extinguisher
- Use a fire extinguisher specifically rated for Class B fires, which are designed to handle flammable liquids like gasoline.
- Place the fire extinguisher near fuel storage areas for easy access in emergencies.
Step 2: Use the Fire Extinguisher Correctly
- Pull the Pin: Start by removing the safety pin.
- Aim: Direct the nozzle at the base of the fire. Extinguishing the flames at the base will prevent the gasoline from feeding the fire further.
- Squeeze: Squeeze the handle firmly.
- Sweep: Use a sweeping motion to cover the entire area of the fire. Continue until the fire is completely extinguished.
Step 3: Alternative Methods Without an Extinguisher
If no Class B fire extinguisher is available, you can still fight a small fire using common household materials like:
- Sand or Dirt
Smother the flames by covering the area entirely with sand or dirt. This cuts the fire off from oxygen, halting combustion.
- Baking Soda
Ideal for very small fires, baking soda can neutralize flames by releasing CO₂ when heated.
Important: Avoid using water or flammable materials like cloths or paper to extinguish the fire. Water can spread the fire, and flammable materials can escalate its intensity.
Safety Precautions During and After the Fire
Follow these critical safety measures when putting out a gasoline fire:
- Avoid Smoke Exposure
Gasoline fires emit toxic fumes. If you inhale too much smoke, move to open air and seek medical attention if needed.
- Beware of Flashbacks
Even after the flames are extinguished, residual gasoline vapors can reignite if exposed to a heat source or spark.
- Leave Major Fires to Professionals
If the fire grows uncontrollable, prioritize your safety and wait for emergency services to address the situation.
Preventing Gasoline Fires at Home
Store Gasoline Properly
- Always use approved, air-tight containers clearly labeled for gasoline storage.
- Store these containers in cool, well-ventilated areas, away from potential ignition sources.
Clean Spills Immediately
- Wipe away gasoline spills promptly. Dispose of used rags in a metal container with a lid to prevent combustion.
Avoid Smoking Near Gasoline
- Never smoke or use open flames near fuel tanks, containers, or spill areas.
Maintain Equipment
- Regularly inspect your lawn mowers, snow blowers, and other fuel-powered devices for leaks or damage.
When to Call Emergency Services
Knowing when to step back and leave it to the professionals is critical:
- The Fire is Out of Control
If flames spread rapidly or the fire becomes too large to handle.
- Property is at Risk
Act quickly if the fire threatens buildings or vehicles.
- Health Risks Arise
Seek immediate help if anyone suffers burns or smoke inhalation.
Calling 911 ensures trained firefighters arrive promptly to manage the situation safely and effectively.
Keep Your Family and Property Safe
Gasoline fires in your backyard or driveway can be deadly, but the right preparation and knowledge can make all the difference. By ensuring you have tools like a Class B fire extinguisher nearby and practicing proper fuel storage habits, you’ll minimize risks and be well-equipped to handle small incidents safely.
Remember, safety always comes first. If there’s any doubt about your ability to control a fire, call emergency services immediately. By staying informed and prepared, you can create a safer environment for your loved ones.
