The Class B Fire Extinguisher

The most suitable fire extinguisher for flammable liquids is the Class B fire extinguisher. This type of extinguisher is specifically designed to combat fires involving flammable liquids and gases. It is essential to understand the characteristics and operating procedures of a Class B fire extinguisher to ensure safety in case of emergencies.

Identifying A Class B Fire Extinguisher

A Class B fire extinguisher can be identified by its unique label, which contains a pictograph of a flame over a letter ‘B’. The letter ‘B’ signifies that it is designed for flammable liquid fires. It is important to always check the label to ensure that you have the correct type of extinguisher for the potential fire hazard.

The Types Of Class B Fire Extinguishers

There are various types of Class B fire extinguishers available, each suited for different flammable liquids. The most common types are:

Type of Extinguisher Extinguishing Agent
Foam Fire Extinguisher Aqueous Film-Forming Foam (AFFF)
Carbon Dioxide (CO2) Fire Extinguisher Carbon Dioxide
Dry Chemical Fire Extinguisher Dry Chemical Powder

Foam Fire Extinguisher

A foam fire extinguisher is effective for fires involving flammable liquids such as gasoline, diesel fuel, and oil. The extinguishing agent, Aqueous Film-Forming Foam (AFFF), creates a thick layer that suppresses the fire and helps to prevent reignition.

Carbon Dioxide (CO2) Fire Extinguisher

A CO2 fire extinguisher is ideal for fires involving flammable liquids and gases. The carbon dioxide displaces oxygen, smothering the fire and effectively extinguishing it. This type of extinguisher leaves no residue behind, making it suitable for use in areas with sensitive equipment or food preparation areas.

Dry Chemical Fire Extinguisher

A dry chemical fire extinguisher is versatile and can handle fires involving flammable liquids, gases, and electrical equipment. The dry chemical powder creates a barrier that inhibits the fire’s access to oxygen, effectively extinguishing it. It is important to note that the residue from a dry chemical extinguisher can be corrosive, so proper cleanup is necessary after use.

Using a Class B Fire Extinguisher

Knowing how to operate a Class B fire extinguisher correctly is crucial for effective firefighting. Remember the acronym ‘PASS’ to ensure proper usage:

  • Pull – Pull the pin on the extinguisher.
  • Aim – Aim the nozzle at the base of the fire.
  • Ssqueeze – Squeeze the handle to discharge the extinguishing agent.
  • Ssweep – Sweep the nozzle from side to side, covering the entire fire area.

It is essential to stand at a safe distance from the fire while operating the extinguisher. If the fire becomes uncontrollable, do not hesitate to evacuate and call emergency services immediately.

Additional Safety Measures

While having the right fire extinguisher is crucial, it is equally important to take additional safety measures when dealing with flammable liquids. Some key points to consider include:

  • Store flammable liquids in containers with proper seals and away from sources of ignition.
  • Ensure proper ventilation in areas where flammable liquids are used or stored.
  • Follow all safety guidelines and regulations for handling and transferring flammable liquids.
  • Regularly inspect and maintain fire extinguishers to ensure their effectiveness.
  • Train employees or household members on fire safety procedures, including the correct use of fire extinguishers.


Choosing the right fire extinguisher for flammable liquids plays a vital role in fire safety. A Class B fire extinguisher that is appropriate for the specific type of flammable liquid is essential. Understanding the different types of extinguishers available and how to use them correctly is crucial for effective firefighting. Remember, prevention is key, so always take the necessary safety measures when dealing with flammable liquids.
