Which type of fire extinguisher is suitable for electrical fires and burning liquids?

The correct choice is suitable for fires involving flammable liquids and electrical equipment. Fire extinguishers are classified based on the type of fire they can effectively extinguish.

Class B extinguishers are specifically designed for fires that involve flammable liquids such as gasoline, oil, and grease, which are common in both industrial and household settings. Class C extinguishers are intended for use on electrical fires caused by the failure or malfunction of electrical equipment. When combined, the designation B:C signals that the extinguisher is effective against both burning liquids and electrical fires, making it versatile for situations where these types of hazards may coexist.

This combination is crucial because using the wrong type of extinguisher can be dangerous. For example, using a water-based extinguisher (Class A) on an electrical fire can lead to electrical shock, and using it on flammable liquids could cause the fire to spread. Therefore, a B:C extinguisher is a safe and effective choice for addressing these specific fire hazards.
