There are a variety of types of fire extinguishers available to the public, using different materials/liquids to fight fires. Such types of fire extinguishers include:

  • Water Extinguishers
  • Foam Extinguishers
  • Powder Extinguishers
  • CO2 Extinguishers
  • Wet Chemical Extinguishers
  • Lithium L2 and M28 Powder Extinguishers
  • Stainless Steel Extinguishers

Types of Fire Extinguishers:

 

Water Extinguisher

Firstly, the water extinguisher is pretty self explanatory. It fights fires through spraying water out of the nozzle. The water extinguisher is best used against solid organic materials, such as wood, paper, plastics, coal, etc. Not for use against burning fat or electrical appliances.

 

Foam Extinguisher

Secondly, theĀ Foam Extinguisher shoots a special cream, resulting in a layer of foam in between the flames and fuel surface. This type of extinguisher is suitable for fires involving both burning solids and liquids. However, this extinguisher is not suitable for use on fat pan and chip fires.

 

Powder Extinguisher

Thirdly, the powder extinguisher. This extinguisher fights fire through a special powder which makes the flames too cool to continue a chemical reaction. The powder extinguisher is suitable or use against organic solids, grease/oil, petrol and gas fires. Whilst safe on live electrical equipment, you shouldn’t use it for electricals, as it can’t easily reach all spaces in equipment. Lithium L2 and M28 Powder extinguishers also fall under this category.

CO2 Extinguishers

Fourthly, CO2 extinguishers shoot carbon dioxide, effectively suffocating the fire, as a fire needs oxygen to continue its chemical reaction. However, ones discharged, the CO2 can dissipate quickly, allowing the fire to potentially reignite. CO2 extinguishers are also suitable for live electrical equipment, however it allows for the possible re-ignition of hot plastic.

 

Wet Chemical Extinguisher

Next, the Wet Chemical Extinguisher is perfect for class F fires involving chip fires, cooking oils & fats, etc. Furthermore, these types of fire extinguishers are often used in kitchens and other places where oils are heated to high temperatures. This extinguisher sprays out a fine mist which sits as a layer of foam at the top of the material.

 

Stainless Steel Extinguishers

Lastly, stainless steel extinguishers. Whilst these are all made out of stainless steel, they come in a variety of variants. Ranging from water to foam, powder to CO2. A steel extinguisher is effectively a highly resistant case for your firefighting lifeline.
