What type of fire extinguisher should be used on ordinary combustibles?

The appropriate fire extinguisher for ordinary combustibles, which include materials such as wood, paper, cloth, and many plastics, is labeled as class A. Class A extinguishers are specifically designed to handle fires involving these types of materials by using water or foam to extinguish the flames effectively.

The effectiveness of a class A extinguisher lies in its ability to cool the burning material and remove heat, suppressing the fire until it is completely out. This makes class A extinguishers essential in residential settings, offices, classrooms, and similar environments where ordinary combustibles are prevalent.

Understanding the classifications of fire extinguishers is crucial for safety and ensures that the proper type is used in various fire scenarios, as using the wrong type can lead to ineffective fire suppression and potentially endanger lives and property.
