Best Answer

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

Class B and E CO2 fire extinguishers are used for fires involving electrical apparatus. They have no post fire security which means that the fire could reignite.

Dry Powder Blue

Class A, B and C Dry powder extinguishers can be used on Class A, B and C fires. Dry powder is not recommended for use inside because it can obscure vision and damage goods and machinery.

Wet Chemical

Yellow Class F Wet chemical extinguishers are for fires involving cooking fats and oils. They are most suitable for use in restaurants and kitchens.

The fire extinguisher contents are designed to interact with the fuel/air boundary, so you need to aim at where the fuel is burning, that is, "at the base of the flames."
