Which term refers to observable effects of fire on materials such as charring or glazing?

• A. Fire Growth Rate
• B. Fire Origin
• C. Fire Scene Reconstruction
• D. Fire Effects

Answer: (D)

Observable effects of fire on materials, such as charring or glazing, describe the actual physical changes heat and combustion cause on objects and surfaces. This is what investigators document to understand how the fire interacted with the materials present. Charring shows that wood or other fuels were exposed long enough to carbonize, while glazing indicates high heat causing a surface to become glassy or melt. Other terms relate to different aspects: how fast the fire grew, where it originated, or the overall process of interpreting the scene. So, the observable material changes are called fire effects.
