To use the right fire extinguisher, it is first important to get a know-how of its types. Below are some of these: 

  • Class A: Fires involving ordinary combustibles such as wood, paper, or cloth.
  • Class B: Fires involving flammable liquids or gases.
  • Class C: Fires involving electrical equipment.
  • Class D: Fires caused by flammable metals.
  • Class F: Fires caused by cooking oils and fats.

This classification of fires helps workplaces and their employees understand the type of fire hazard that may occur and how to effectively deal with it. 

For instance, in a wood production factory, the workers should know that a class-A fire is most likely to occur. Therefore, these factories should set up fire extinguishers that deal with class A types of fire as safety hazards.

Types of Fire Extinguishers

After getting familiar with the classes of fire, let us have a look at some types of commonly used fire extinguishers:

  • Foam extinguishers: Foam fire extinguishers are suitable for both Class A and Class B types of fire. It employs foam to dampen down the flames.
  • Carbon Dioxide (CO2) extinguishers: As the name tells CO2 fire extinguishers to use carbon dioxide to extinguish the fire and are used for Class B and Class C types of fires.
  • Dry powder extinguishers: It uses dry powder to dampen the fire. This is to keep in mind that dry powder can be messy and should be handled with proper tools. This type of fire extinguisher is used for all classes of fires (A, B, C, D, and F).
  • Wet chemical extinguishers: These are suitable for Class F fire types only. The particular liquid type of chemical helps to extinguish the fire. Wet chemical extinguishers are mostly designed for commercial kitchens, where cooking and oils and fats are common fire risks.
