Illustration of a grease fire

If you’re faced with a grease fire, know that fast and correct actions can save your home. Knowing how to put out a grease fire involves immediate steps you can take to extinguish flames safely—like smothering the fire with a metal lid and using baking soda—but equally important is knowing what not to do, such as throwing water on the fire, which can exacerbate the situation. This guide outlines what to do in the crucial first moments of a grease fire and offers practical advice on safely resolving these dangerous situations and the proper extinguishers to use.

Key Takeaways

  • Immediate response to a grease fire is critical and includes smothering the fire with a metal lid, applying baking soda or salt, and using a Class K or B dry chemical fire extinguisher, but never water.
  • The use of water, wet towels, moving the pan, or using incorrect extinguishing agents such as flour can exacerbate a grease fire and should be strictly avoided.
  • Preventing grease fires involves understanding cooking oils’ smoke points, maintaining a clean and tidy cooking environment, and taking swift action to evacuate and call emergency services if the fire becomes uncontrollable.

Understanding Grease Fires

A grease fire is not your typical house fire. It begins when cooking oil becomes too hot, leading to boiling, smoking, and eventually igniting. The result? A voracious fire that can cause significant damage and even threaten lives by igniting other combustible items and spreading throughout the home. Home cooking fires, like grease fires, are a scenario that no one wants to face, but being prepared is crucial.

One essential rule when dealing with grease fires is never to use water to put them out. Water and oil don’t mix, and in the context of a fire, this can lead to disastrous results. When water is thrown onto burning oil, it vaporizes instantly, expanding and carrying the burning oil with it. The result can be a huge fireball that spreads the fire rapidly and intensifies the heat.

Understanding the nature of grease fires is the first step towards handling them effectively. By knowing what causes them and what can make them worse, we can take steps to prevent them and react appropriately if one does occur.

Immediate Actions to Extinguish a Grease Fire

When a grease fire starts, immediate action is crucial. Knowing what to do in those first few seconds can prevent a small flame from turning into a devastating blaze. We’ll explore three immediate actions to extinguish a grease fire: smothering it with a metal lid, applying baking soda or salt, and using a fire extinguisher.

Smother with a Metal Lid

One of the most effective ways to extinguish a grease fire is to smother it with a metal lid or cookie sheet. By sliding a metal lid over the burning pan, you deprive the flame of the oxygen it requires to burn, effectively suppressing the fire. It’s important to use oven mitts or metal tongs to shield your hands from the heat.

However, not all lids are suitable for this. Specifically, you should avoid using glass lids. Glass can shatter from the intense heat of the fire, creating additional hazards when used as a heat source.

Once the lid is in place, it’s crucial to leave it there until it is cool. Removing the lid prematurely could reintroduce oxygen and cause the fire to reignite. The aim is to completely smother the fire, eliminating its source of oxygen.

Apply Baking Soda or Salt

Baking soda and salt are common household items that can be used to put out a grease fire. These substances work by depriving the flames of oxygen, thereby extinguishing the fire. When baking soda is heated, it produces carbon dioxide gas, which can smother a grease fire.

However, using baking soda or salt to extinguish a grease fire requires a sufficient amount to smother the flames. A small sprinkle won’t be enough; you need to pour on a liberal amount to effectively smother the fire.

Remember, while baking soda and baking powder are effective, not all powders are created equal when it comes to fire suppression. Flour, for example, should not be used to suppress a grease fire.

Activate a Fire Extinguisher

Fire extinguishers are a common sight in many homes and are an essential tool in fighting fires. However, not all fire extinguishers are the same. For a grease fire, a Class K fire extinguisher, specifically designed for kitchen fires, is the right choice. Wet chemical extinguishers are an example of Class K fire extinguishers. If a Class K extinguisher is not available, a Class B dry chemical extinguisher can be an alternative.

Using a fire extinguisher should be considered a last resort due to the risk of contaminating the kitchen area with chemicals. It’s also crucial not to use the wrong type of fire extinguisher. Employing the wrong type of extinguisher can exacerbate the situation, making it more dangerous.

Understanding Smoke Alarm Chirps

Smoke alarms are our silent guardians, but when they start chirping, they can be quite vocal about it. Keep in mind that not all chirps are created equal. They can be the alarm’s way of communicating various issues, from a simple battery change to more serious problems.

Understanding each type of smoke alarm chirping noise helps with identifying the cause of the chirping. The initial steps in assessing a smoke alarm include checking for smoke and assessing the pattern of beeping. Knowing the difference between a low battery warning, an end-of-life signal, or a malfunction alert can save you a lot of trouble—and a lot of sleep!

Mistakes to Avoid During a Grease Fire

While knowing what to do in a grease fire is crucial, it’s equally important to understand what not to do. Certain actions can worsen the situation, turning a manageable fire into a full-blown inferno.

First and foremost, never pour water on a grease fire. The rapid vaporization of water can spread burning grease around, making the fire worse. It’s also vital not to move the pan that’s on fire. Doing so could cause hot oil to spill out, leading to burns and spreading the fire.

Using a wet towel to smother a grease fire is another mistake to avoid. The moisture in the towel can create steam and cause the grease to splatter, spreading the fire. Finally, don’t use flour or similar fine powders to extinguish a grease fire. These substances can contribute to a dust explosion or worsen the flames.

Strategies for Grease Fire Prevention

Prevention is always better than cure. This principle holds true for grease fires. By understanding the characteristics of cooking oils, monitoring the cooking process, and maintaining kitchen cleanliness, we can prevent grease fires and significantly reduce the risk of such incidents.

Know Your Cooking Oils

An essential step in preventing grease fires is understanding the smoke points of different cooking oils. Each oil has a unique smoke point, the temperature at which it starts to smoke and can catch fire. For instance, avocado oil can withstand high temperatures, making it ideal for searing. On the other hand, olive oil is better suited for medium-heat cooking like sautéing.

Not all oils are created equal. Refined oils can endure higher temperatures before smoking, compared to unrefined oils, which typically offer more nutritional value. Furthermore, the smoke point of cooking oils can decrease with repeated use, making oils with initially high smoke points more versatile and longer-lasting.

Knowing the smoke points of various oils and choosing the right one for your cooking method can significantly reduce the risk of a grease fire when you heat oil.

Regular Maintenance and Cleanliness

A clean kitchen is not only a pleasant place to cook but also a safer one. Grease fires can spread to other parts of the kitchen where grease splatters are present, which is why keeping your kitchen clean is crucial in fire prevention.

One effective way to clean up grease spills is to sprinkle baking soda over the affected areas. Baking soda is a recommended method for cleaning grease spills, as it helps to break down the grease and make it easier to wipe away.

What to Do If You Can’t Control the Fire

Despite our best efforts, there may be times when a grease fire becomes uncontrollable, or even electrical fires occur. In such cases, it’s important to remember that property can be replaced, but lives cannot.

If a grease fire gets out of control, the first action should be to:

  1. Evacuate the area immediately.
  2. Once everyone is safely out of the area, call emergency services.
  3. Don’t attempt to fight a large fire yourself; professional firefighters are trained to handle such situations.

The key is not to delay in calling for help. Fires can escalate rapidly, and every second counts. If there’s any doubt about your ability to extinguish a small grease fire safely, it’s imperative to call the fire department at 911 immediately.


In conclusion, understanding grease fires is the first step towards handling them effectively and safely. Knowing how to extinguish a grease fire quickly, the common mistakes to avoid, and the strategies for prevention can help ensure your safety and that of your loved ones. Remember, when it comes to fires, prevention is always preferable, but being prepared for the worst is equally important. At A&J Fire Extinguisher, we understand that one of the most crucial tools to prevent fires from escalating is a reliable fire extinguisher. Let’s keep our kitchens, the heart of our homes, safe and fire-free.
