How should different classes of fire be treated?

Different classes of fire are defined based on the materials that are burning, and each class requires specific extinguishing agents and methods to be effectively managed. This specificity is crucial because using the wrong type of extinguishing agent can exacerbate the fire or create additional hazards.

For example, Class A fires involve ordinary combustibles like wood, paper, and cloth, and they can be effectively fought with water. However, Class B fires involve flammable liquids such as gasoline or oil, where water is not only ineffective but can also spread the fire. These require foam, dry chemical agents, or certain types of extinguishing powder. Class C fires pertain to energized electrical equipment, where using water can conduct electricity and pose a severe risk of electrocution, necessitating the use of non-conductive agents such as carbon dioxide or dry chemicals.

Understanding the nature of the materials involved in each fire class allows firefighters to choose the proper method and extinguishing agents, ensuring they handle the situation safely and effectively. Hence, recognizing the need for targeted strategies based on the class of fire is crucial for fire prevention and safety practices.
