One of the most important factors in fire safety is your fire extinguishers, but fire extinguishers are not a one size fits all solution for your business. Here, we will take a look at acquiring the right fire extinguishers for your business or property, and the importance of fire extinguisher maintenance and inspection.

When Do You Need Fire Extinguishers?

You are likely to require fire extinguishers if you are in non-domestic or multi-occupied premises. This includes HMOs and converted flats, as well as businesses. It is also essential that the people on the premises have the correct knowledge of fire extinguishers. This will allow them to safely use an extinguisher if there is an emergency. While you do not need to be an expert, it is a great idea to be fully aware of the correct fire extinguisher to use in each situation. You should also take extinguisher maintenance seriously and consider hiring a fire extinguisher maintenance company.

Types Of Fire Extinguisher

There are different types of fire extinguishers, which are applicable to certain classes of fire. Some extinguishers are suitable for use on multiple types of fire, such as a Water Mist extinguisher. However, it is often a good idea to stick to the specialist equipment for each fire class.

In order to make identifying different extinguishers easy for everyone, the varying types will have different coloured labels.

Class A fires are the most common, involving solid materials such as wood and paper. You can use Water (red label), Foam (cream label), or Water Mist fire extinguishers for these.

Class B fires involve flammable liquids and are best combated with a Foam (cream label) fire extinguisher, but you can also use a Water Mist extinguisher.

Class C fires are caused by gasses and are best fought by using a Powder (blue label) fire extinguisher. Again, you can also use a Water Mist extinguisher on these fires.

Class D fires are caused by flammable metals and require highly specialist powder extinguishers (also a blue label). Not to be confused with regular powder extinguishers.

Class F fires are caused by fats and fatty oils, such as for cooking, and can only be put out with Wet Chemical (yellow label) or Water Mist fire extinguishers.

Electrical fires are also fairly common and involve electrical equipment. They are best combated using a Carbon Dioxide (CO2) (black label) extinguisher. Water Mist and some Foam extinguishers can also be used on electrical fires but must show the 35kVA electrical safety symbol.


In order to make using fire extinguishers as easy as possible for those within the building, suitable fire extinguishers will need to be located and installed as applicable to the specific fire hazard in each area. Think about what type of fire is most likely in each area before installing the extinguishers.
