Cooking is a joy that brings people together, but it can also come with unexpected dangers. Grease fires are one of the most common—and most hazardous—accidents that can occur in the kitchen. They ignite without warning, spread rapidly, and if handled incorrectly, can cause injuries and significant property damage.
This blog will teach you everything you need to know about grease fire safety, from understanding how they occur to learning step-by-step how to put them out safely. By the end, you'll feel confident about preventing grease fires and how to handle them should the unthinkable happen.
What Causes a Grease Fire? Understanding the Science
Grease fires happen when cooking oils or fats are overheated. Every type of oil has a "smoke point"—the temperature at which it starts to smoke and break down. For many oils, this starts around 375°F to 450°F. If the oil continues to heat beyond the smoke point, it can reach its "flash point," causing the oil to ignite.
Unlike general fires that can be doused with water, grease fires thrive on it. Water evaporates in the hot oil, causing flammable oil droplets to disperse and feed the flames, creating an explosive effect.
Knowing these basics helps you understand why grease fires behave the way they do, making it easier to prevent them and extinguish them effectively.
Prevention First: Avoiding Grease Fires
The best approach to grease fire safety is prevention. Here are crucial steps to help you avoid them in the first place:
- Never Leave Cooking Unattended
Most grease fires happen when people walk away from a hot pan or fryer. Always stay nearby and keep a close watch.
- Use the Right Cooking Oil
Choose oils with a high smoke point, such as avocado or peanut oil, for high-temperature cooking.
- Don’t Overheat Oil
Monitor the temperature of your oil. Use a thermometer to ensure it stays below the smoke point. Fryers commonly have built-in settings for this purpose—use them.
- Keep Flammable Items Away
Keep towels, paper towels, and wooden utensils far from the stovetop to avoid accidental flare-ups.
- Clean Grease Buildup Regularly
Grease buildup on your stovetop, pans, or range hood can catch fire. A quick wipe-down after each use works wonders.

How to Safely Put Out a Grease Fire
Even with the best precautions, grease fires can still occur. If you find yourself facing a small grease fire in your kitchen, follow these steps to stay safe:
1. Turn Off the Burner
Your first priority is to remove the heat source. Turn off the burner or stovetop immediately to prevent the fire from growing.
2. Cover the Flames with a Lid
If the fire is small, carefully slide a metal lid or a cookie sheet over the pan to smother the fire by cutting off its oxygen supply. Don't remove the lid until the pan cools completely.
3. Use Baking Soda or Salt
For tiny fires, you can extinguish flames by pouring baking soda or salt directly onto the fire. Be sure not to use flour or baking powder—they're flammable and will worsen the fire.
4. Use a Fire Extinguisher
If the flames spread beyond the pan, or if you're unsure how to proceed, immediately use a Class B fire extinguisher. These are specially designed for grease and flammable liquid fires.
5. Call 911 If the Fire Grows
If the fire becomes unmanageable or starts to spread across surfaces, evacuate your home and call 911. Never attempt to fight large fires on your own.
What NOT to Do During a Grease Fire
Grease fires can escalate if not handled properly. Here are the most critical mistakes to avoid when dealing with one:
- Never Use Water
It's tempting, but water will aggravate the flames and cause the fire to spread violently.
- Don’t Move the Pan
Attempting to move a flaming pan can cause hot oil and flames to spill onto yourself or other surfaces, spreading the fire.
- Avoid Using Fabric or Paper to Smother Flames
Materials like kitchen towels or paper products are highly flammable and will ignite almost immediately, adding fuel to the fire.
- Don’t Ignore the Fire’s Severity
If the fire doesn't get smaller after you’ve taken steps to extinguish it, evacuate and call for professional help.
Cleaning Up and Restoring Your Kitchen
After successfully extinguishing the fire, it’s essential to clean up thoroughly and assess the damage. Here's how to do it safely and effectively:
- Ventilate the Area
Open windows and use fans to clear the smoke and reduce lingering odors.
- Clean the Affected Area
Remove any charred pots and utensils, and clean surfaces with grease-cutting solutions.
- Inspect for Damage
Ensure your range hood, countertops, and surrounding appliances are undamaged. If anything looks compromised, replace or repair it.
- Dispose Safely
Properly dispose of burnt grease or oil. Seal it in a container and follow local guidelines for disposal.
- Restock Emergency Items
Replace used items such as fire extinguishers or damaged lids.
