Which statement is true regarding the use of dry powder extinguishing agents on Class D fires?

The statement that no single extinguishing agent will control or extinguish fires in all combustible metals is accurate. Class D fires involve combustible metals such as magnesium, titanium, and sodium, which have unique burning characteristics. Each type of combustible metal may require a specific drying powder extinguishing agent tailored to its properties to effectively suppress the flames.

Some dry powder agents are designed for specific metals, while others may not work effectively depending on the type of metal involved in the fire. This variability is crucial for firefighters to understand, as using an inappropriate agent could lead to the fire exacerbating instead of being extinguished. Proper training and knowledge about the characteristics of combustible metals and the corresponding extinguishing agents help ensure the safety and effectiveness of fire suppression efforts involving Class D fires.
