Understanding Class B Fires:  Prevention and Extinguishing

When it comes to fire safety, understanding the different classes of fires is crucial for effective prevention and response. Class B fires, often referred to as flammable liquid fires, are a common type of fire hazard. In this informative blog post, we’ll explore what a Class B fire is, its causes, and the fire extinguishers that can be used to combat them.

What Is a Class B Fire?

Class B fires are fires involving flammable liquids. These can include a wide range of liquids, such as gasoline or oil. These types of fires are characterised by their ability to spread rapidly, producing intense flames and potentially hazardous situations. They can occur in various settings, from industrial facilities to homes, making it essential to be prepared for such emergencies.

Causes of Class B Fires

Class B fires can be sparked by various factors, including:

1. Spills and Leaks: Accidental spills or leaks of flammable liquids are common causes of these types of fires. Even a small spill can ignite if exposed to a spark or open flame.

2. Electrical Faults: Faulty wiring or electrical equipment can produce sparks that ignite nearby flammable liquids.

3. Human Error: Careless handling of flammable substances, such as smoking near fuel storage areas, can lead to flammable liquid fires.

4. Equipment Malfunctions: Mechanical failures in machinery that handle or store flammable liquids can cause fires.

Extinguishing Class B Fires

When dealing with a Class B fire, choosing the right fire extinguisher is crucial for effective suppression. There are a few types of fire extinguishers suitable for flammable liquid fires:

1. Carbon Dioxide (CO2) Fire Extinguishers: CO2 extinguishers displace oxygen, suffocating the fire. They are highly effective for Class B fires and leave no residue, making them ideal for use around sensitive equipment. These extinguishers can also be used against Electrical fires, making them very useful.

2. Foam Fire Extinguishers: Foam extinguishers create a barrier over the surface of the flammable liquid, cutting off its oxygen supply and cooling the fire simultaneously. They are suitable for Class A and Class B fires.

3. Dry Powder Fire Extinguisher: Dry Powder extinguishers release a fine chemical powder onto the fire. This powder interrupts the fire’s chemical reaction by smothering the flames and preventing oxygen from reaching the fuel source. Dry powder extinguishers are effective against Class A, B, C and Electrical fires.

3. Clean Agent Fire Extinguishers: Clean agents work by interrupting the chemical reaction without leaving any residue. They are ideal for flammable liquid fires and are environmentally friendly.


Understanding Class B fires and having the right fire extinguisher on hand is essential for effective fire safety. Whether at home or in the workplace, being prepared for these types of fires can save lives and property. 

Always ensure that your fire extinguishers are up to date and regularly inspected and that you and those around you are familiar with their proper use in case of a fire-related emergency. By being informed and prepared, you can help protect yourself and potentially your loved ones against the devastating consequences of flammable liquid fires.
