In terms of fire classes, what does Class D specifically refer to?

Class D specifically refers to combustible metals in the classification of fire types. This classification is crucial for understanding how to effectively combat different types of fires, as metals can burn at extremely high temperatures and may react dangerously to water and other standard extinguishing agents.

Knowing this helps responders prepare for the unique challenges posed by metallic fires. For instance, materials like magnesium or titanium require specific extinguishing agents such as dry powder materials that are designed for metal fires, unlike the methods typically used for flammable liquids or electrical fires that are classified under different categories. Recognizing the specific behavior and risks associated with combustible metals is essential for ensuring safe and effective firefighting strategies.
