What symbol represents a Class A fire extinguisher?

A Class A fire extinguisher is indicated by a green triangle symbol. This classification is used for fires that involve ordinary combustibles such as wood, paper, cloth, and some plastics. The green triangle helps firefighters and individuals quickly identify the type of extinguisher needed for this kind of fire, ensuring that an appropriate response is executed to effectively extinguish the flames.

In contrast, the other symbols represent different classes of fire extinguishers: a red square typically indicates a Class B extinguisher, which is used for flammable liquids; a blue circle denotes a Class C extinguisher for electrical fires; and a yellow star is used for Class D extinguishers, which are designed for combustible metals. Understanding these symbols is crucial for safety and effective fire management.
