Fire Extinguisher Classes and Suitability

Each type of fire extinguisher is suitable for different types of burning media and will have a fire rating based on the volume of fire that they are capable of extinguishing. Below is an overview of each type of fire extinguisher including its rating and suitable uses.

CLASSIFICATION

SUITABILITY

Dry Powder

good for class a suitable for class b suitable for class C unsuitable for class F suitable for electrical fire

Ideal for use in mixed risk environments and offer excellent all round fire protection. With a unique class C rating, powder fire extinguishers are the only effective solution for fires involving flammable gases.

AFFF (Foam)

Ideal for use on fire involving solid combustible materials and are highly effective on flammable liquid fires. The layer of foam applied by these extinguishers helps to prevent re-ignition after the fire has been extinguished.

CO2

Suitable for use on flammable liquid fires and are extremely effective at extinguishing fire involving electrical equipment. CO2 is also one of the cleanest extinguisher agents and leaves no residue behind.

Water

Suitable for use in environments containing solid combustible materials such as wood, paper and textiles. It is important to remember that water conducts electricity and should not be used around electrical equipment (unless water extinguishers with additive are used).

Classes

Fires are identified using a classification system. Each class identifies the type of fuel involved and allows appropriate fire extinguisher media to be identified.
