What are fire extinguishers classified based on?

Fire extinguishers are classified primarily based on the type of fires they are designed to control. This classification is essential because different types of fires require specific extinguishing agents to effectively suppress them. For example, Class A extinguishers are suited for ordinary combustible materials like wood and paper, while Class B extinguishers are intended for flammable liquids such as gasoline and oils. Class C extinguishers are used for electrical fires, and Class D extinguishers are for combustible metals.

Understanding these classifications allows users to choose the appropriate fire extinguisher for the specific hazard they may encounter, enhancing safety and effectiveness in emergency situations.
