What type of fire extinguisher is suitable for electrical fires?

• A. Aqueous film-forming foam (AFFF)
• B. Carbon dioxide (CO2)
• C. Wood wool
• D. Water-based extinguishers

Answer: (B)

The most suitable fire extinguisher for electrical fires is carbon dioxide (CO2). CO2 extinguishers work by displacing oxygen in the area around the fire while also cooling the burning materials. This is particularly effective for electrical fires, as CO2 does not conduct electricity, making it safe to use on live electrical equipment. Other types of extinguishers, such as aqueous film-forming foam (AFFF) and water-based extinguishers, can pose risks when used on electrical fires. AFFF extinguishers may not be suitable because they contain water and can conduct electricity, which could lead to further hazards. Similarly, water-based extinguishers, which are effective on materials like wood and paper, should never be used on electrical fires as the water can cause shock or worsen the fire condition by making the electrical components more conductive. Thus, carbon dioxide extinguishers are specifically designed to combat fires fueled by electrical sources without the risk of conducting electricity, making them the ideal choice in these situations.
