Types of Fire Extinguishers to Use for Class B Fires and Their Applications

In modern society, fire hazards pose a serious threat to people's lives and property, especially when different types of fires require different extinguishing methods. Using the wrong fire extinguisher could exacerbate the fire, making it even more dangerous. Understanding the correct fire extinguisher to use for different types of fires is crucial. This article focuses on Class B fires and the appropriate fire extinguishers to use in the event of such fires.

What Are Class B Fires?

Class B fires refer to fires caused by flammable liquids and gases. Common examples of Class B fires include those caused by oils, gasoline, alcohol, solvents, natural gas, and other flammable liquids or gases. These types of fires cannot be extinguished effectively with water, as water may spread the fire or worsen the situation. Therefore, choosing the appropriate fire extinguisher is key to controlling a Class B fire.

Types of Fire Extinguishers for Class B Fires

1. Foam Fire Extinguisher
   Foam fire extinguishers are an ideal choice for extinguishing Class B fires, especially those involving oils and liquid fuels. Foam works by creating a blanket over the burning surface, cutting off the oxygen supply and extinguishing the fire. Foam extinguishers are highly effective in putting out most oil fires and, due to their coverage properties, help prevent re-ignition.

2. Dry Powder Fire Extinguisher
   Dry powder fire extinguishers are another highly effective tool for Class B fires. The principle behind dry powder extinguishers is the release of a fine chemical powder that interferes with the chemical reactions necessary for combustion. Dry powder extinguishers are not only suitable for Class B fires but also for Class A (solid combustibles), Class C (electrical fires), and even Class D (metal fires). They are particularly useful in environments with oil fires or chemical solvent fires, offering fast action and excellent results.

3. Carbon Dioxide (CO₂) Fire Extinguisher
   CO₂ fire extinguishers are commonly used to combat Class B fires involving oils and solvents. The working principle of CO₂ extinguishers is to rapidly release carbon dioxide gas, reducing the oxygen concentration around the fire and thereby extinguishing the flames. CO₂ fire extinguishers are also safe to use around electrical equipment, as they leave no residue and do not cause damage to sensitive machinery.

4. Halotron Fire Extinguisher (Halogenated Fire Extinguisher)
   Halotron extinguishers are highly effective for Class B fires, especially in environments where fire suppression is needed without causing environmental damage or equipment harm. Halotron works by chemically interrupting the combustion process, offering a clean, efficient way to put out fires in sensitive environments, such as data centers or industrial sites where equipment protection is paramount.
