Whether you're a home cook whipping up dinner or a parent making breakfast for the kids, knowing how to handle a grease fire is a critical skill. This blog will guide you through understanding grease fires, safely extinguishing them, and preventing them from happening in the first place.
By the end of this article, you'll feel more confident about protecting your home and loved ones in the heat of the moment.
Understanding Grease Fires
Before tackling a grease fire, it's important to understand how they start and why attempting to extinguish them with water can make things worse.
What Causes a Grease Fire?
A grease fire occurs when cooking oil or fat reaches its "smoke point"—the temperature where it begins to smoke and break down. This temperature varies depending on the type of oil but is generally between 325°F and 450°F (163°C to 232°C).
Once the oil overheats beyond the smoke point, it can catch fire, often ignited by nearby heat sources like the stovetop burner. Adding food or liquids to overheated oil can also trigger a flash fire.
Common causes of grease fires include:
- Leaving cooking oil unattended on high heat
- Overheating oil while deep-frying
- Pouring wet or frozen ingredients into hot oil
- Not maintaining a clean stovetop, leading to grease buildup
Why You Should Never Use Water
It's instinctive to douse a fire with water, but this is the absolute worst thing you can do in a grease fire situation. Water and burning oil react violently, often causing the fire to explode outward. This spreads flames further across your kitchen and can lead to severe burns.
Instead, grease fires require oxygen deprivation, heat removal, or chemical extinguishers to effectively put them out.

A Step-by-Step Guide to Safely Extinguishing a Grease Fire
If a grease fire erupts in your kitchen, staying calm is key. Follow these steps to handle it safely and effectively.
1. Turn Off the Heat
The first step is to eliminate the heat source that's fueling the fire. Turn off the burner or stovetop immediately, but do so cautiously to avoid getting too close to the flames.
2. Do Not Use Water or Flour
Remember: water will make the fire worse. Similarly, do not use flour, sugar, or baking powder, as these can ignite and worsen the flames.
3. Cover with a Metal Lid or Baking Sheet
Cutting off the fire's oxygen supply is one of the most effective ways to extinguish it. If possible, carefully place a metal lid or baking sheet over the flames. Avoid using glass, as it can shatter under high heat.
4. Use Baking Soda or Salt (if small and manageable)
For smaller grease fires, pour a generous amount of baking soda or salt directly onto the flames. These materials smother the fire by absorbing heat and cutting off oxygen. Always keep some baking soda handy in your kitchen as a precaution.
5. Use a Fire Extinguisher (Class B or ABC)
If the fire is too large to manage with the steps above, grab your fire extinguisher. Ensure it is a Class B or ABC extinguisher—designed for flammable liquids like oil. Aim at the base of the fire and use short bursts to smother it.
6. Evacuate and Call 911 if Necessary
If the fire continues to spread or feels uncontrollable, evacuate your home immediately. Close the door to contain the fire as much as possible and call 911 for emergency assistance. Property can be replaced—your life cannot.
Preventing Grease Fires
The best way to deal with a grease fire? Prevent it from happening in the first place. Here are some preventative tips to keep your kitchen safe.
Practice Safe Cooking Habits
- Never leave hot oil or grease unattended on the stove.
- Use a deep fryer with temperature controls to prevent overheating.
- Dry food thoroughly before adding it to hot oil to prevent splattering.
- Always cook with the handles of your pots and pans turned inward to avoid accidental spills.
Maintain a Clean Kitchen
Grease build-up on stovetops, ovens, and range hoods is a common fire hazard. Make it a habit to wipe down cooking surfaces and equipment after each use.
Use the Right Cooking Oil
Different oils have different smoke points. Choose oils with higher smoke points for frying, such as avocado oil or peanut oil, to reduce the risk of overheating.
Be Prepared
- Keep a Class B or ABC fire extinguisher in your kitchen and ensure everyone in your household knows how to use it.
- Have baking soda and salt accessible—but NOT flour or sugar.
- Install working smoke detectors in your kitchen and regularly check their batteries.
Real-Life Lessons in Handling Grease Fires
Success Story
Jane, a busy mom of three, was frying chicken wings when the oil overheated and caught fire. Because she had prepared for such an event, she quickly turned off the heat, covered the pan with a metal lid, and smothered the flames with baking soda. The fire was extinguished in seconds, and her kitchen (and family) remained unharmed.
Cautionary Tale
On the other hand, Tim, a college student, panicked when his skillet caught fire while cooking bacon. Forgetting his kitchen safety basics, he poured water onto the flames. The fire quickly spread, engulfing the curtains and causing significant damage to the apartment. Fortunately, Tim escaped unharmed, but the incident served as a stark reminder of why preparation matters.
