The UK Fire Extinguisher Colour Code System
The UK follows a specific colour-coding system for fire extinguishers. This system uses colours on both the body and the label to indicate the type of extinguishing agent on the inside.
In the UK, the colour of all fire extinguishers is red, specially named signal red. A coloured panel on the label is used to differentiate between the various types of fire extinguishers. This labelling system allows users to easily identify where fire extinguishers are located and the type of extinguishing agent inside the extinguisher. So, what colours are used for different extinguishing agents?
Types of Fire Extinguishers and Their Colours
Water Fire Extinguisher Colour
Water fire extinguishers have an all-red body. These red fire extinguishers are suitable for Class A fires involving solid materials like wood, paper and textiles. They work by cooling the fire. Remember, water fire extinguishers should not be used on electrical fires!
Foam Fire Extinguisher Colour
Foam extinguishers come in the signature signal red colour but have a cream-coloured panel. A cream fire extinguisher is effective against Class A and Class B fires, which involve flammable liquids like petrol or oil. The foam creates a blanket over the fire, smothering it and preventing re-ignition.
Dry Powder Extinguisher Colour
These dry powder extinguishers are red with a blue panel on the front. These blue fire extinguishers contain a fine powder that effectively smothers the fire. They are very versatile as they can be used on Class A, B and C fires. Some dry powder extinguishers are also suitable for electrical fires.
CO2 Fire Extinguisher Colour
Carbon dioxide fire extinguishers are red on the outside with a black panel. A black fire extinguisher is ideal for electrical fires and Class B fires. They work by using carbon dioxide to displace oxygen, starving the fire of its fuel. These extinguishers leave no residue, making them suitable for use around sensitive equipment.
Wet Chemical Fire Extinguisher Colour
With a yellow panel, wet chemical extinguishers are specially designed for Class F fires involving cooking oils and fats. Yellow fire extinguishers work by creating a soap-like substance that cools and seals the surface of the oil, preventing it from reigniting.
Fire Classes and Their Corresponding Fire Extinguishers
Fire classes are defined by the fuel source of the fire. We have summarised the fire classes and the appropriate fire extinguisher to help you understand what to reach for in the event of a fire.
It is important to note that electrical fires don’t have a specific fire class. For fires involving electrical equipment, it is best to use carbon dioxide or dry powder extinguishers.

Understanding Fire Extinguisher Labels
Fire extinguisher labels provide crucial information at a glance. They typically include:
The same label may also be placed in the form of a sign on the fire extinguisher stand or near a fire extinguisher. These labels reiterate the same information to ensure you have read and understood the type of fire extinguisher you are using.
