What term refers to the borders or boundaries of fire patterns?

• A. Fire Boundaries
• B. Perimeter Lines
• C. Lines of Demarcation
• D. Heat Lines

Answer: (C)

Lines of demarcation describe the borders where the fire’s effects end and undamaged area begins. This boundary shows the edge of a burn pattern and marks the transition from burned to unburned material, which helps investigators map how the fire spread and where it originated. Recognizing these lines lets you see the extent and direction of damage, assess whether a single ignition caused the pattern, and identify any anomalies that might suggest accelerants or multiple sources. While other phrases might sound related, lines of demarcation is the standard term used to denote the border of a fire pattern.
