Final answer:
Fires from combustible metals produce a "class D fire," which involves metals like magnesium, titanium, lithium, potassium, and sodium. These fires burn at high temperatures and produce unique flame colors that can help identify the metal.
Step-by-step explanation:
Fires from combustible metals produce what is known as a "class D fire." Class D fires involve combustible metals such as magnesium, titanium, lithium, potassium, and sodium. These metals have the ability to catch fire and burn at high temperatures, often with a very bright flame. When these metals burn, they can produce unique flame colors that can be used to identify the metal involved.
