There are different types of fire extinguishers, each designed to combat specific types of fires. The most common types of fire extinguishers include:

  1. Water-based extinguishers: These extinguishers are effective against fires caused by ordinary combustible materials, such as wood, paper, and cloth.
  2. Foam extinguishers: Foam extinguishers are suitable for fires based on flammable liquids like gasoline, oil, and solvents. The foam creates a barrier between the fuel and the oxygen, smothering the fire.
  3. Carbon dioxide (CO2) extinguishers: CO2 extinguishers are ideal for electrical fires and fires involving flammable liquids. The carbon dioxide displaces oxygen, effectively suffocating the fire.
  4. Dry chemical extinguishers: Dry chemical extinguishers are versatile and can be used on various types of fires, including those caused by electrical equipment, flammable liquids, and combustible materials.
  5. Wet chemical extinguishers: Wet chemical extinguishers are designed for fires involving cooking oils and fats commonly found in kitchens.

Classification of Fire Extinguishers

The classification system for fire extinguishers is based on the type of fuel involved in the fire. Here are standard-based classifications of fire extinguishers and usage. 

  1. Class A: These kinds of extinguishers are meant for fires involving common combustible items like paper, wood, cloth and plastic. They utilize foam or water as its fire extinguishing agent.
  2. Class B: These types of extinguishers are used for fires based on flammable liquids like gasoline, oil, grease, and solvents. They typically use dry chemical agents, such as carbon dioxide (CO2) or dry powder.
  3. Class C: These extinguishers are designed for fires involving energized electrical equipment, such as appliances, wiring, and circuit breakers. They use non-conductive agents like CO2 or dry powder to suppress the fire without conducting electricity.
  4. Class D: These kinds of extinguishers are created for fires involving combustible metals like sodium, potassium, titanium and magnesium. They use special dry powder agents to smother the fire and prevent re-ignition.
  5. Class K: These types of extinguishers are used for fires involving fats, greases and cooking oil commonly found in commercial kitchens. They use a wet chemical agent that reacts with the hot oil to form a soapy foam, cooling and suppressing the fire.

It’s important to note that some fire extinguishers are multi-purpose and can be effective against multiple classes of fires. However, it is crucial to select the right fire extinguisher based on the specific fire hazards present in your environment. Additionally, it is recommended to have proper training on how to use the fire extinguisher effectively and safely.
