Class F Fires

Understanding Class F Fires and Fire Extinguisher Ratings

Fire safety is a massive concern for everyone, and it’s crucial to be well-informed about the different types of fires and the right tools to combat them. In this blog post, we will focus on Class F fires, which are fires that involve cooking oils and fats. We will also discuss how Class F fire ratings are assigned to fire extinguishers.

What Are Class F Fires?

Class F fires are a specific category of fire involving cooking oils and fats, such as vegetable oil, animal fat, or even butter. These fires are common in kitchens and other areas where cooking or frying is taking place. Unlike other fire classes, Class F fires are particularly dangerous due to the high temperatures and the potential for the fire to quickly spread if not extinguished properly.

Common causes of these fires include:

1. Overheated oil or fat in cooking pans.

2. Splashes of hot oil onto stovetops.

3. Ignition of grease-laden appliances.

Understanding Class F Fire Extinguisher Ratings

To effectively combat Class F fires, it’s essential to use the right fire extinguisher or firefighting tool. Fire extinguishers are labelled with specific fire class ratings to indicate the types of fires they are suitable for. In the case of Class F fires, specific fire extinguishers must be used. These are likely Wet Chemical fire extinguishers or a not-so-common MultiCHEM fire extinguisher. To find out more about these fire extinguishers, check out a more detailed blog post regarding them HERE.

Class F fire extinguisher ratings typically follow a standard system, which makes it easy for users to select the appropriate extinguisher for the scenario in which they will be placed. These ratings are expressed as “Class F” or “F” and are often accompanied by numerical ratings. For example, you might see an extinguisher labelled as “75F.”

The numerical value accompanying the “Class F” designation represents the scale of the extinguisher’s protection. The number directly correlates to the size of the deep fat fryer it can be used against. For example, a 75F-rated fire extinguisher can be used on all deep fat fryers that are 75 litres and below.  It’s crucial to select an extinguisher with a rating appropriate for the size of the kitchen and the potential fire hazards present.


Understanding Class F fires and knowing how to use Class F fire extinguishers is essential for kitchen safety. Whether you’re a professional chef or a home cook, being prepared for a Class F fire can make all the difference in preventing a minor incident from turning into a major disaster. Always check the fire extinguisher’s rating when choosing a fire extinguisher for a commercial or industrial kitchen.

By following these guidelines and being informed about Class F fires. Hopefully, this can give you the information you need to keep your kitchen and cooking areas safe.

Fire Blankets: A Must-Have Safety Tool for Every Home and Workplace

Fire blankets are an essential safety tool that often goes unnoticed until a fire emergency strikes. These simple yet effective devices play a crucial role in fire prevention and suppression. In this blog post, we will explore what fire blankets are, how they work, and the various ways in which they are used to protect lives and property.

What Are Fire Blankets?

A fire blanket is a piece of fire-resistant fabric, typically made from materials such as fibreglass or a specially treated wool. They are designed to extinguish small fires by cutting off the fire’s oxygen supply, thus smothering the flames. Fire blankets are compact and easy to use, making them an ideal tool for quickly responding to early-stage fires.

How Do Fire Blankets Work?

The fundamental principle behind the effectiveness of a fire blanket is suffocation. When a fire blanket is placed over a fire, it deprives the flames of oxygen, which is essential for combustion. Here’s a step-by-step guide on how fire blankets work:

1. Identify the fire: Ensure that it’s safe to use a fire blanket on the fire, and if it’s a small, contained fire like a grease fire in the kitchen.

2. Pull the fire blanket from its storage pouch or container.

3. Hold the corners of the fire blanket and approach the fire carefully.

4. Gently lay the blanket over the fire, covering it completely and sealing off the flames’ oxygen supply.

5. Leave the fire blanket in place until the fire is extinguished or until professional help arrives.

It’s important to remember that fire blankets work most effectively on small fires. For larger fires, a fire extinguisher or immediate evacuation should be the primary course of action.

Uses of Fire Blankets

1. Kitchen Fires: One of the most common uses of fire blankets is in the kitchen to extinguish grease fires. They are invaluable for containing small stovetop fires and preventing them from spreading.

2. Fire Safety in Laboratories: Fire blankets are often used in laboratories to extinguish small chemical fires. They can also be used to protect individuals who might be in danger during a lab experiment gone wrong.

3. Emergency Fire Blanket: Fire blankets are essential components of fire safety kits, both at home and in the workplace. They are placed in strategic locations for easy access during fire emergencies.

4. Welding and Industrial Settings: A fire blanket can be used to protect against sparks, splatter, and small fires in welding and industrial settings, where hot metal and open flames are common.

5. Emergency Evacuations: A fire blanket can also be used to wrap around individuals in emergency situations to protect them from smoke and heat while exiting a burning building.

Most Common Use

Fire blankets are most commonly used to tackle kitchen fires, especially pan fires, categorised as Class F fires. These fires typically involve cooking oils, fats, and greases and are prevalent in household kitchens. When a kitchen fire erupts, a fire blanket can be quickly and effectively deployed to smother the flames.

This type of fire is the common use of these fire blankets due to them being the perfect size for the blanket to handle. The pan offers a contained location for the fire, and after it is covered by the blanket, it makes the fire very restricted and keeps the user safe.

Gently placing the fire blanket over the flaming pan, prevents the fire’s access to oxygen, extinguishing it without the need for water or other potentially dangerous extinguishing agents. Using a fire blanket in this manner not only helps prevent the fire from spreading but also minimizes the risk of injury and property damage. Kitchen fires are a common scenario where a fire blanket can prove its worth, making it an indispensable safety tool for every home.

Our Fire Blankets

The fire blankets that we offer at Fireology come in three varying sizes. These are Small (1m x 1m), Medium (1.2m x 1.2m) and Large (1.8m x 1.2m).


A fire blanket is a simple yet highly effective tool for fire safety. It offers a quick and easy way to suppress small fires and protect individuals in emergency situations. Every home and workplace should have one of these blankets readily available and regularly checked to ensure they are in good condition. 

Remember, while fire blankets are valuable, they are not a substitute for other fire safety measures like smoke detectors and fire extinguishers. Fire safety is a collective effort. Still having the right tools and knowledge is essential for preventing and managing fire emergencies effectively.

Kitchen Fires: Causes, Prevention, and Safety Tips

The kitchen is often considered the heart of the home, a place where families gather to prepare and share meals. However, it is also one of the most common areas for household fires to occur. In this informative blog post, we will explore the causes of kitchen fires, how to prevent them, and important safety tips to keep you and your loved ones safe.

Causes of Kitchen Fires  

1. Cooking Unattended:

One of the leading causes of kitchen fires is leaving food unattended on the stove or in the oven. A momentary distraction can quickly lead to disaster.

2. Grease and Oil Fires:

Cooking with oil can be dangerous, as it can easily ignite if it becomes too hot. Grease fires can spread rapidly and are difficult.

3. Flammable Objects Near the Stove:

Towels, pot holders, paper towels, and other flammable materials left too close to a hot burner can catch fire.

4. Electrical Appliances:

Faulty or misused electrical appliances, such as toasters, microwaves, or coffee makers, can also be a source of kitchen fires.

5. Gas Leaks:

Stoves that use gas can be dangerous if there is a leak. Gas leaks are often accompanied by a strong odour, but they can sometimes go unnoticed until a fire occurs.

Preventing Kitchen Fires

1. Stay in the Kitchen:

Whenever you are cooking, stay in the kitchen to keep an eye on the food. Avoid leaving the kitchen unattended, especially when using the stovetop or oven.

2. Maintain Appliances:

Regularly inspect and maintain your kitchen appliances, such as stoves, ovens, and microwaves, to ensure they are in good working condition.

3. Keep Flammable Objects Away:

Keep flammable materials like dish towels, pot holders, and paper towels away from the stove and other hot surfaces.

4. Use Oil with Caution:

When cooking with oil, use a deep fryer thermometer to monitor the oil’s temperature. Never overheat it, and always keep a lid nearby to smother any flames if a grease fire occurs.

5. Install a Smoke Detector:

Make sure your kitchen is equipped with a smoke detector, and test it regularly to ensure it is functioning correctly.

Safety Tips for Kitchen Fires

1. Know How to Use a Fire Extinguisher:

Keep a fire extinguisher in the kitchen and know how to use it. The PASS (Pull, Aim, Squeeze, Sweep) method is the most common technique for using a fire extinguisher.

2. Never Use Water on Grease Fires:

Water can cause a grease fire to spread rapidly. Instead, use a fire extinguisher or cover the pan with a lid to smother the flames.

3. Use a Fire Extinguisher or a Fire Blanket:

If a small fire breaks out, you can use an appropriate fire extinguisher (likely Class F) or a fire blanket to smother the flames.

4. Call 911:

If a fire gets out of control, evacuate your home immediately and call 911 for professional help.

Class F Fires

Class F fires are a specific category of fires primarily involving cooking oils and fats, particularly in commercial kitchens and restaurants. These fires are characterised by the ignition of hot cooking oils and fats, which can quickly become extremely dangerous due to their high temperatures and the potential for splattering and spreading. 

Class F fires pose a unique challenge because they cannot be effectively extinguished with water, as water can cause the burning oil to splatter and spread the flames. Instead, specialised fire suppression systems and extinguishing agents, such as Wet Chemical fire extinguishers, are used to control and extinguish Class F fires safely. 

These extinguishing agents work by cooling the oil and creating a barrier to prevent re-ignition. Proper training and equipment are crucial when dealing with Class F fires to minimise the risk of injury and property damage in commercial kitchen environments.


Kitchen fires are a serious safety concern, but with proper precautions, they can be prevented. Always stay vigilant while cooking, keep your kitchen well-maintained, and know how to respond in case of a fire emergency. By following these guidelines, you can help ensure that your kitchen remains a safe and enjoyable place for cooking and sharing meals with your loved ones.
