Fire safety is essential in both residential and commercial settings. Understanding fire classification categories helps determine the appropriate fire extinguisher to use in different situations. Fires are classified based on the type of fuel involved, making it easier to select the correct suppression method.

Fire Classification Categories

Class A – Fires involving common combustible materials like wood, paper, textiles and some plastics. . Class B – Fires caused by flammable liquids such as petrol, oil, grease and solvents. . Class C – Fires involving electrical equipment. Once the power is removed, they can be treated as Class A fires. . Class D – Fires that involve combustible metals like magnesium, titanium, sodium and potassium. . Class K – Fires caused by cooking oils and fats, commonly occurring in commercial kitchens.
