Fire Extinguisher Classes

The fire classification system is designed to categorise fires into groups based on the type of fuel involved. Each fire class is represented by a letter of the alphabet (with the exception of electrical which are simply referred to as "electrical fires") and an icon. This helps users to select an appropriate fire extinguisher in the event of a fire.

	Class B Fires	Flammable Liquids Fires involving flammable liquids such as petrol, diesel, oils, paraffin etc.
	Class C Fires	Flammable Gases Fires involving flammable gasses such as propane, hydrogen, methane, natural gas etc.
	Class D Fires	Flammable Metals Fires involving flammable metals such as magnesium, lithium, potassium, sodium etc.
	Class F Fires	Combustible Cooking Media Fires involving combustible cooking media such as cooking oils and fats.
