While it is widely known that there are multiple types of fires, most people do not realise that there are actually six different types. According to the UK government the six different fire types with their combustible component can be found below:

Class A – organic solids (eg. paper, wood)

Class B – flammable liquids (eg. petrol, spirits)

Class C – flammable gasses (eg. propane, butane)

Class D – burning metals (eg. magnesium, lithium)

Class F – cooking oil and fat (eg. olive oil, butter)

Electrical Fires – electrical equipment (eg. computers, printers). A symbol for an electrical spark is used rather than the letter E

There are a total of 8 different types of fire extinguishers. The extinguishers you require will depend on the use of your space and the potential hazards that may be present. Luckily, our engineers have the knowledge and experience required to direct you as necessary. The information below summarises the different type of fire extinguisher with their colour codes and the fires that they extinguish:


Type BS EN 3 Colour Code Fire Class
Water Red A
Water Mist White and Red A, F
Foam Red with a cream panel above the operating instructions A, B
Dry Powder Red with a blue panel above the operating instructions A, B, C, electrical
Carbon Dioxide Red with a black panel above the operating instructions  B, electrical
Wet Chemical Red with a yellow panel above the operating instructions A, F
Specialist Powder Red with a blue panel above the operating instructions D


British Legislation states that it is mandatory for fire extinguishers to comply with the above colour coding which is why having the knowledge about fire extinguisher colours is important to have control over emergency situations shall they arise.

BS EN3 is the most up to date EU standard which ensures that all fire extinguishers conform to one coding system. The BS EN3 standard replaced the previous regulation in 1997 and has been strictly followed for over 20 years.

Fire extinguishers for fire classes A, B and F each carry a rating. The fire ratings are a number that indicates the size and severity of the fire that it will be effective against. The larger the number, the bigger fire it can extinguish. The fire ratings will always be displayed as a number next to the fire class (eg 3A, 15B, 25F). Class C, D and the electrical symbol carry no fire rating system.

Extinguishers capable of extinguishing class F fires have a four-tier rating system. Class F extinguishers are all tested at 4 benchmark levels of 5, 15, 25, and 75 litres of cooking oil. If an extinguisher can exceed this benchmark level it will be have the rating corresponding to its ability. For example, if a fire extinguisher can put out a fire of 25 litres of cooking oil it will have the rating 25F.

There are regulations governing how often fire extinguishers must be serviced in commercial and public buildings. The BS 5306-3 (2017) regulations stipulate how often fire extinguishers need servicing. Fire extinguishers should be visually inspected monthly for damage or pressure loss and serviced once a year. All water, foam and powder extinguishers must be emptied and refilled every five years. CO2 extinguishers must also be refurbished after ten years. There is an exception with the Britannia P50 servicing-free extinguishers which only need to be serviced after ten years (visual inspections are still required). After an extinguisher has been used it must also be refilled even if it was only partially used.

Our engineer’s are fully trained to deal with all aspects of servicing and maintaining fire extinguishers so if you have further questions or enquiries regarding  fire extinguishers for you or business, please call us on 01942 562 021.
