Why Should I Install Fire Extinguishers?

Fire extinguishers are a crucial element of fire protection and fire safety, so it is important that your premises has the right type of extinguishers available and installed correctly for safe usage. When purchasing fire extinguishers for the first time, it is a good idea to have a specialist installer such as Spire Security carry out a site survey to recommend the correct type and locations for your new extinguishers. There are several different types of fire extinguisher, all of which are suited for different types of fires and flammable materials.  The different types of fire are referred to as Fire Classes.

Class A Fires: these involve organic solids such as wood and paper
Class B Fires: these involve flammable liquids
Class C Fires: these are fires involving flammable gasses
Class D Fires: These are fires involving burning metals (such as aluminium swarf)
Class F Fires: fires involving fats such as those used in deep fat fryers
Electrical Fires ( the letter E is not used, instead the symbol of an electrical spark is shown) : fires caused by electrical equipment

Each fire class has it’s own type of extinguisher best suited to putting out the fire. These are colour coded to indicate the extinguisher medium used. New fire extinguishers are manufactured to the standard BS EN 3.

The Right Extinguishers for You

Depending on the fire risks in your business premises, you may require more than one type of extinguisher to suit the potential flammable materials used. The different types of extinguisher match up to the different fire classes described above.

Foam Extinguishers : Used on burning solids (class A) and liquids (class B), foam is an excellent choice for most general office requirements.

Wet Chemical Extinguishers : these are used on fat fires and deep fat fryers (class F). The chemical bonds with the burning fat and stops the supply of oxygen to the fat.  Used in professional kitchens.

Water Extinguishers : Only used on class A fires, water cools down the fire and prevents re-ignition.  Newly developed dry water mists can be used on class A, B, C and F fires.

Powder Extinguishers : Also known as ABC powder or dry powder. These are versatile and can be used for class A, class B and class C fires. They cannot be used on class F as the jet would spread the burning fat. Not to be used in confined spaces, as the powder can easily be inhaled.

CO2 Extinguishers : these units use pure carbon dioxide to suffocate fire and leave behind no residue once the fire is extinguished.  They are mainly used for fire fighting on live electrical equipment, so they are often installed next to foam extinguishers in offices with computers.

Spire Security can work with you to create a plan for the ongoing servicing and maintenance of your fire extinguishers.  It is important that your extinguishers are regularly serviced to ensure they function correctly should they ever be needed! It is the responsibility of a business owner or responsible person for a building to ensure that extinguishers are serviced in accordance to the BS 5306-3:2017. This does not apply to maintenance-free P50 fire extinguishers.
