What does the smoke color for a Class Delta fire depend on?

The smoke color for a Class Delta fire is primarily influenced by the type of metal being burned. Class Delta fires involve combustible metals such as magnesium, titanium, sodium, and potassium. Each metal produces different combustion reactions, which generate distinct colors of smoke due to the specific byproducts formed during combustion. For example, burning magnesium can produce bright white smoke, while other metals may yield various shades depending on their chemical properties.

Understanding the behavior of different metals in a fire situation is critical for fire suppression efforts, as the specific characteristics of the smoke can also impact visibility and safety during firefighting operations. Thus, recognizing the type of metal can inform responders about not only the smoke color but also the additional hazards and appropriate methods for extinguishing the fire.
