What symbol is used to designate a class C fire extinguisher?

A class C fire extinguisher is designated by a blue circle. This symbol indicates that the extinguisher is suitable for use on electrical fires, which can occur in situations involving live electrical equipment or wiring. The blue circle signifies the specific nature of the extinguishing agent used in class C extinguishers, which is typically non-conductive, reducing the risk of electrical shock when used.

Understanding the classifications and symbols of fire extinguishers is essential for effective fire safety and prevention. Recognizing the different classes of fires—A (ordinary combustibles), B (flammable liquids), C (electrical), D (metal), and K (cooking oils and fats)—and their corresponding extinguisher symbols ensures that individuals can quickly identify the right type of extinguisher to use in the event of a fire. This knowledge not only enhances personal safety but also helps in maintaining a safe environment in workplaces and public spaces.
