Which classes of fires are recognized in fire extinguisher use?

The classes of fires recognized in fire extinguisher use are Class A, B, C, and D. Class A fires involve ordinary combustibles such as wood, paper, and cloth. Class B fires occur with flammable liquids and gases like gasoline or oil. Class C fires are associated with electrical equipment, and Class D fires involve combustible metals such as magnesium or potassium.

Understanding these classifications is essential for properly selecting and using fire extinguishers, as each class requires different types of extinguishing agents to effectively combat the specific fire type. This classification system ensures that individuals can respond appropriately to different fire situations, enhancing safety and effectiveness in fire management.
