What can be considered a characteristic of Class D fuels?

Class D fuels specifically refer to combustible metals, which include materials such as magnesium, titanium, sodium, and potassium. These metals burn at high temperatures and require special extinguishing agents for fire suppression. Understanding the classification of fires is critical for ensuring proper handling and response techniques, as different materials require different firefighting approaches due to their unique burning characteristics.

The reference to geographic location, combustibility at lower temperatures, or the nature of organic materials pertains to other fire classes and does not accurately categorize Class D fuels. Firefighters must be equipped with knowledge about these fuels to respond effectively and safely when dealing with metal fires, as their behavior in combustion is distinct from other fuel classes.
