How should you aim a fire extinguisher's stream when extinguishing a fire?

The stream should be aimed directly at the base of the fire. This will extinguish the source of the flame. Aiming it at the flame itself will have little impact. Always use the correct type of extinguisher for the fire source

Class A - fires involving solid materials such as wood, paper or textiles.

Class B - fires involving flammable liquids such as petrol, diesel or oils.

Class C - fires involving gases.

Class D - fires involving metals.

Class E - fires involving live electrical apparatus. (Technically 'Class E' doesn't exists however this is used for convenience here)

Class F - fires involving cooking oils such as in deep-fat fryers.

Water Red

Class A Water extinguishers are used on Class A fires. They are not suitable for fires fuelled by flammable liquids or where electricity is involved.

Foam Cream

Class A and B Foam is a versatile fire extinguisher. Used for Class A and B fires.

CO2 Black
