Fire Extinguisher Types
Fires are divided into five main types, depending on the nature of the fuel involved:
Class A fires involve solid fuels, such as wood
Class B fires involve flammable liquids, such as petrol
Class C fires involve gas
Class D fires involve metals, such as potassium or magnesium
Class F fires involve cooking oils
Before this classification system, there was a classification of electrical fires, but since electricity itself is a cause of fire, these types of fires have been incorporated into the main classes. Once you have turned off the electricity the fire becomes the same as any other.
This table shows, at a glance, the fire extinguisher types suitable for each class.
