Removing and inspecting debris can reveal whether an item burned from the top down or bottom up. Which term describes this burn direction?

• A. The time of ignition
• B. The color of smoke
• C. The direction of burn
• D. The fuel type

Answer: (C)

The concept here is burn direction. When you remove and inspect debris, you can see how the fire progressed through the object—whether flames and scorching moved from the ceiling downward or from the floor upward. That observed progression is described as the direction of burn. This helps determine where the fire originated and how it spread.

Other terms don’t describe this progression. The time of ignition tells you when the fire started, not which way it traveled. The color of smoke reflects combustion conditions and material involved, not the burn direction. The fuel type identifies what fed the fire, not the direction it burned.
