Fire extinguishers are designed to tackle specific types of fire and there are six different classes of fire and several different types of fire extinguishers, which are as follows:-
Water extinguishers are one of the most cost-effective ways to fight Class A fires, those fuelled by solid materials such as paper, wood and textiles.
All water extinguishers have a red label and the four different types of water extinguishers are: water jet, water spray, water with additives and water mist or fog.
Foam fire extinguishers can be used on Class A and B fires. They are most suited to extinguishing liquid fires such as petrol or diesel and are more versatile than water jet extinguishers because they can also be used on solids such as wood and paper. Foam extinguishers have a cream label.
Powder extinguishers are a good multi-purpose fire extinguisher because they can be used on Class A, B and C fires. They can also be used on fires involving electrical equipment however, they do not cool the fire so it can re-ignite. Powder extinguishers have a blue label.
Carbon dioxide extinguishers (CO2)
CO2 extinguishers are ideal for places with a lot of electrical equipment such as offices or server rooms because they are safe to use on fires involving electrical apparatus. Carbon Dioxide Extinguishers (CO2) have a black label.
Wet chemical extinguishers
Wet chemical extinguishers are suitable for use on Class F fires involving cooking oils and fats, such as lard, olive oil, sunflower oil, etc. They have a yellow label.
Fire blankets are primarily used on hot oil fires such as frying pans or small deep fat fryers. They can also be used on someone whose clothing has caught fire by the person smothering the fire.
