Fires are classified into how many distinct classes?

Fires are classified into four distinct classes based on the type of fuel that is burning. These classifications help in determining the appropriate firefighting methods and equipment to be used in extinguishing the fire.

Class A fires involve ordinary combustible materials such as wood, paper, and cloth. Class B fires involve flammable liquids like gasoline and oils. Class C fires occur with energized electrical equipment, making it critical to use non-conductive extinguishing agents. Class D fires involve combustible metals, which require specialized extinguishing methods.

Understanding these classes is vital for ensuring safety protocols are followed during firefighting and training. By categorizing fires, responders can efficiently manage and combat them while minimizing risks to themselves and surrounding environments.
