Fire Extinguishers

There are 5 main fire extinguisher types generally in use – Water, Foam, Dry Powder, CO2 and Wet Chemical. It is important that you choose the correct type for your premises, or you may not meet current regulations.

The various types of extinguisher are then classified as to their ability and appropriateness for putting out fires that are started with different types of fuel. The risk to your premises by these 'classes’ assist in determining the most appropriate fire extinguisher types you need. Very often more than one type of extinguisher will be required.

In addition to choosing the right type of extinguisher you will also need to make sure that you have the right size and weight of fire extinguisher as well as the right kind.

  • Class D fires – combustible metals: chemicals such as magnesium, aluminum or potassium
  • Electrical fires – electrical equipment: once the electrical item is removed, the fire changes class
