Smoke color for Class Delta fire?

Smoke color for Class Delta fire?

• A. Depends on the metal being burned
• B. Blue or white
• C. Black or brown
• D. Red

Answer: (A)

Class Delta fires involve combustible metals, and the smoke they produce isn’t fixed. The color of the smoke depends on which metal is burning and the specific metal-oxide particles formed during combustion. For example, magnesium fires often produce bright white smoke, while other metals can generate white, gray, or even differently tinted plumes. Because there isn’t one universal smoke color for all metal fires, the best answer is that the smoke color depends on the metal being burned.
