When it comes to fire safety, not all fires are the same. One of the most dangerous and challenging types of fires involves cooking oils and fats. These fires, categorized as Class F fires, require a specialized approach to extinguish safely and effectively. This is where oil extinguishers, commonly known as wet chemical extinguishers, come into play. In this article, we’ll explore what oil extinguishers are, how they work, and why they are indispensable in kitchens and industrial settings.
What is an Oil Extinguisher?
An oil extinguisher, technically referred to as a wet chemical extinguisher, is designed specifically to combat fires involving high-temperature cooking oils and fats. These extinguishers contain a potassium-based solution that cools the fire and creates a barrier over the burning oil, preventing re-ignition. They are highly effective and are the only recommended extinguishers for Class F fires.
Why Are Oil Fires Dangerous?
Oil fires are uniquely hazardous due to several factors:
- High Ignition Temperatures: Cooking oils and fats can reach temperatures exceeding 200°C, making them prone to spontaneous ignition.
- Re-ignition Risk: Residual heat in the cooking vessel or surrounding area can reignite the fire, even after the initial flames are extinguished.
- Water Danger: Pouring water on oil fires can cause the fire to spread explosively. When water hits hot oil, it instantly vaporizes into steam, propelling burning oil droplets into the air.
These risks make oil fires one of the most dangerous types, especially in environments like commercial kitchens where large quantities of oil are used.
How Does an Oil Extinguisher Work?
Oil extinguishers use a wet chemical agent to combat oil fires through a multi-step process:
- Cooling Effect: The liquid solution rapidly cools the burning oil and surrounding surfaces, reducing the risk of re-ignition.
- Saponification Process: When the chemical comes into contact with the hot oil, it reacts to form a thick, soapy layer. This layer smothers the flames and seals the surface of the oil, cutting off its oxygen supply.
- Smothering Flames: The barrier prevents oxygen from reaching the fire, effectively extinguishing it and stopping the chemical reaction.
This unique mechanism makes oil extinguishers the safest and most effective choice for Class F fires.
When and Where to Use an Oil Extinguisher
Oil extinguishers are essential in any setting where cooking oils and fats are used, including:
- Domestic Kitchens: For households that frequently use deep fryers or large quantities of oil.
- Commercial Kitchens: In restaurants, fast food outlets, and catering businesses where industrial deep fryers are common.
- Food Processing Facilities: Industrial settings that handle oils in bulk for food production.
They are also required in compliance with fire safety regulations in many jurisdictions, including the UK.
Steps to Use an Oil Extinguisher Safely
- Assess the Situation: Ensure the fire is not too large or spreading uncontrollably. If it is, evacuate immediately and call emergency services.
- Pull the Safety Pin: This prepares the extinguisher for use.
- Aim at the Base of the Fire: Position the nozzle towards the burning oil, ensuring the extinguisher is held upright.
- Discharge the Extinguisher: Squeeze the handle and apply the chemical in a controlled, sweeping motion, covering the entire surface of the fire.
- Monitor for Re-ignition: Once the flames are out, observe the area to ensure the fire doesn’t reignite.
Proper training in using oil extinguishers is crucial for effective fire response.

Oil Extinguishers vs. Other Extinguishers
While oil extinguishers are ideal for Class F fires, other types of extinguishers are not suitable:
- Water Extinguishers: Can worsen oil fires by spreading burning oil droplets.
- Foam Extinguishers: Effective for Class B fires but not as efficient for hot cooking oils.
- CO2 Extinguishers: Useful for electrical fires but may not cool the oil enough to prevent re-ignition.
- Powder Extinguishers: Can extinguish flames but leave a mess and lack the cooling effect needed for oil fires.

Tips for Preventing Oil Fires
- Never Leave Cooking Oil Unattended: Fires often start when oil is overheated without supervision.
- Use a Thermometer: Monitor oil temperature to avoid reaching its flashpoint.
- Clean Grease Buildup: Regularly clean kitchen surfaces and equipment to prevent grease fires.
- Install Fire Suppression Systems: Especially important in commercial kitchens.
