Grease fires are one of the most dangerous types of kitchen fires, often starting in a matter of seconds and spreading rapidly if not addressed correctly. Unlike regular fires, attempting to extinguish a grease fire with water can cause the flames to flare up, creating a fire worse scenario and putting both lives and property at risk. Understanding how to respond quickly, what tools to use, and the preventive measures to take can mean the difference between a minor incident and significant damage.
In this blog, we will cover everything from the causes of grease fires to the following steps you should take to put out a grease fire safely and prevent it in the future.
Explaining Grease Fires
A grease fire occurs when cooking oil, fat, or grease reaches its flash point and ignites. These fires can be extremely volatile, as the burning oil can easily catch fire and spread across the stove, counters, and nearby combustible materials. They are a leading concern in home cooking fires and are responsible for many kitchen-related emergencies reported to the fire department and fire safety authorities, such as the National Fire Protection Association. Unlike ordinary fires, water should never be used, as it can cause the hot oil to splatter and worsen the situation.
Why Grease Fires Start
Grease fires usually happen due to heat mismanagement or unsafe cooking practices. Recognising common causes is key to preventing these incidents.
Overheated Oil
Hot oil is the most frequent culprit in kitchen fires. When oil exceeds its flash point, it can ignite immediately, turning a small flare-up into a dangerous grease fire. Oils like vegetable, peanut, or canola have different ignition temperatures, so monitoring the heat source immediately is critical.
Cooking Fat Left Unattended
Leaving a pan or pot of fat or oil unattended on the stove top is a recipe for disaster. Even small quantities can ignite quickly if heat is not controlled, turning home cooking fires into emergencies that could cause significant damage.
Flammable Items Near Heat
Items like baking sheets, towels, flour, or paper can catch fire if placed too close to a burner or grill. Even larger quantities of flammable food ingredients like baking powder or kosher salt stored nearby can contribute to fire spread in the kitchen.
Immediate Steps to Take
Knowing how to put out a grease fire safely requires calm, quick action and the right materials. Following these steps can greatly reduce the risk of escalation.
Stay Calm and Act Quickly
The first thing to do is stay calm and assess the situation. Panic can cause mistakes, increasing the risk of injury or property damage.
Smother the Flames Safely
Cover the pan or pot with a metal lid or baking sheet to smother the fire and cut off the oxygen supply. A wet towel can also be used carefully to cover small fires, but it must be damp, not soaked, to avoid creating steam that could spread the flames.
Turn Off Heat Sources
Immediately turn off the heat on gas or electric burners to prevent the fire from gaining more intensity. Removing the heat source immediately is essential to control the fire and prevent flare-ups.
Use Appropriate Fire Extinguishers
For more severe fires, a dry chemical fire extinguisher or ABC fire extinguisher is the best bet. These units are designed to extinguish class A, B, or C fires safely. Avoid using water, as it can cause burning oil to splash and make the fire worse.
Keep a Safe Distance While Responding
Maintain a safe distance from the flames and ensure other household members are evacuated. Using long-handled tools and standing back allows you to control the fire safely while reducing the risk of burns.

Preventing Grease Fires in the Kitchen
Prevention is always better than response. Simple habits can significantly lower the likelihood of kitchen fires.
Regular Cleaning and Oil Management
Regular cleaning of the stove, burners, and grill surfaces removes grease buildup, a common contributor to fires. Proper disposal and management of cooking oils further reduce the risk.
Monitoring Cooking Temperatures
Keep an eye on hot oil and fat when cooking. Using a thermometer or monitoring heat levels can prevent oils from reaching their flash point, helping to avoid sudden ignition.
Safe Cooking Practices
Avoid leaving food unattended, maintain a clear workspace free of flammable items, and be mindful of fats, oil, and grease near the heat. Using lids, pots, and proper containers helps extinguish potential small fires before they escalate.
When to Call Emergency Services
Even with precautions, some fires may become uncontrollable. Knowing when to call the fire department is critical.
Fire Spreading Beyond Control
If flames extend beyond the pan, pot, or stove top, evacuate the area immediately and call emergency services. Attempting to fight a spreading grease fire can lead to injury or significant damage.
Smoke or Flames in Multiple Areas
A fire that produces smoke or flames in more than one part of the kitchen or house is a sign of escalation. Quick evacuation and professional intervention are required.
Risk to Yourself or Others
If anyone is at risk from flames or smoke, do not attempt to fight the fire yourself. Safety of household members comes first, and calling the fire department ensures trained personnel handle the situation safely.
Final Thoughts
Grease fires are a leading cause of home cooking fires, but understanding how to put out a grease fire safely can prevent injuries and significant damage. Following the following steps, keeping heat under control, and using appropriate extinguishers or smothering techniques like metal lids or baking sheets can greatly reduce fire risks. For additional protection, residential water mist fire suppression systems offer advanced coverage and rapid response, providing peace of mind in home kitchens and domestic properties. Regular maintenance, awareness, and readiness ensure that kitchen fires remain manageable and safely contained.
