Class C fires involve what type of materials?

Class C fires specifically involve energized electrical equipment. This classification is crucial because the approach to extinguishing a Class C fire differs significantly from other types of fires due to the presence of electricity. Using water or foam on such fires can pose a significant risk of electrical shock to the firefighter and can also potentially damage the electrical equipment.

Firefighting agents suitable for Class C fires often include dry chemical agents or carbon dioxide (CO2), which can effectively extinguish the fire without conducting electricity. Understanding this classification helps responders choose the correct suppression method, ensuring both safety and effectiveness in managing the fire.

In this context, while other classes deal with materials like combustible cooking oils, organic materials, or combustible metals, Class C distinctly refers to the risks and methods associated with electrical fires, making it imperative for facility fire brigade members to have a solid grasp of these classifications.
