Knowing how to put out a gasoline fire is essential, as gasoline fires are among the most dangerous and unpredictable types of fire you can encounter at home. Even a small leak during a routine task, such as refilling your mower or car, can quickly become a hazardous situation. Gasoline vapor easily ignites at low temperatures, and appropriate handling at a fire scene is crucial for ensuring the safety of people and property, particularly with correct processes and equipment.
This article outlines the specific steps to take in the event of a gasoline fire, including immediate actions to stay safe, how to put out a gasoline fire, the tools you need to extinguish it, and preventative measures to avoid getting burned. Whether it’s in the backyard or driveway, being prepared could save lives.
Understanding Gasoline Fires
Prior to discussing how to handle a gasoline fire, it’s crucial to recognize why gasoline fires pose such significant dangers and necessitate particular responses unlike other types of fires.
What Makes Gasoline Fires Unique?
- Low Ignition Temperature
Gasoline is very volatile, meaning it can catch fire even at comparatively low temperatures. One spark or static spark is sufficient to ignite it.
- Rapid Spread
Gasoline spreads quickly over surfaces, and its vapors are combustible, causing flash fires that can cover large spaces in seconds.
- 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
Leaking gasoline from vehicles, motorcycles, or gardening tools during refueling can lead to a hazardous splash fire, particularly if there is a nearby heat source.
- Improper Storage
Gasoline from vehicles, motorcycles, or gardening tools can leak out when being filled up and can produce a dangerous splash fire — especially if there is a heat source nearby.
- 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 may result in hasty errors. Maintain a clear mindset to evaluate the fire correctly and decide on the safest approach.
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 flames spread quickly or seem unmanageable, immediately dial 911 and leave the location.
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
- Utilize a fire extinguisher that is specifically rated for Class B fires, meant to manage flammable liquids such as 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: Aim the nozzle at the fire’s base. Putting out the fire at the bottom will stop the gasoline from fueling the flames more.
- Squeeze: Squeeze the handle firmly.
- Sweep: Employ a broad motion to encompass the complete region of the fire. Keep going until the flames are fully put out.
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
Douse the fire by fully covering the spot with sand or earth. This removes the oxygen supply from the fire, stopping the burning.
- Baking Soda
Ideal for very small fires, baking soda can neutralize flames by releasing CO₂ when heated.
Important: Never attempt to extinguish fire with water or flammable items such as cloths or paper. Fire can spread with water and can be intensified with flammable materials.
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
In case the fire becomes unmanageable, focus on your safety and await emergency personnel to handle the matter.
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
Fires caused by ignited gasoline in your own backyard or driveway can be lethal, but with the proper preparation and information, you can turn things around. Your best defense against a fire damaging your property is to keep a Class B fire extinguisher close at hand and practice good fuel storage habits. These preventive steps will reduce risks and help prevent a small fire from becoming a major problem.
Keep in mind, safety should always be the top priority. If you’re uncertain about your capacity to manage a fire or how to put out a gasoline fire, contact emergency services right away. By staying informed and prepared, you can create a safe environment for your family without concerns about disastrous incidents that might result in selling a fire-damaged house.
