Which fire class would involve materials like rubber and plastics?

The correct classification for materials like rubber and plastics is Class A. Class A fires primarily involve ordinary combustibles such as wood, paper, cloth, rubber, and many types of plastics. These materials are characterized by the ability to ignite and produce ash upon burning.

Class A fires are typically extinguished using water or other methods that cool the burning materials, and fire-fighting agents designed specifically for this class efficiently remove heat and assist in controlling the fire.

Understanding fire classes is essential for effective fire response, as it guides firefighters in selecting the appropriate extinguishing method and agent. In this case, rubber and plastics belong to the solid combustible category, aligning them with Class A characteristics.
