If recyclables ignite due to high temperatures, what class of fire would this represent?

The ignition of recyclables due to high temperatures falls under Class A fires. Class A fires involve ordinary combustible materials, such as wood, paper, cloth, and certain types of plastics. When recyclable materials are subjected to high temperatures, they can react similarly to these ordinary combustibles and ignite.

Class A fires are characterized by the burning of solid materials, which is exactly the case with recyclables like cardboard or paper products. Fire extinguishers designed for Class A fires typically use water or foam to cool the materials and extinguish the flames. Understanding the classification of fires is crucial for selecting the appropriate firefighting measures, ensuring safety in environments where such materials are present.

In contrast, other classes of fire, such as Class B (flammable liquids and gases), Class C (electrical equipment), and Class D (combustible metals), pertain to fires resulting from different materials and require specific types of extinguishing agents. Thus, the correct classification of recyclables that ignite due to high temperatures is Class A.
