What do the symbols on a fire extinguisher indicate?

The symbols on a fire extinguisher are specifically designed to provide crucial information about the size and type of fire that the extinguisher is capable of extinguishing. These symbols indicate the classifications of fires, such as those involving ordinary combustibles (Class A), flammable liquids (Class B), electrical equipment (Class C), and other types. By understanding these symbols, users can quickly identify the appropriate extinguisher to use in an emergency situation, ensuring effective response to different fire scenarios. This knowledge is essential for safety in both recreational boating situations and other environments.
