Which term describes the apparent design of burned material and the burning path of travel from the origin?

• A. Fire pattern
• B. Fire load
• C. Vent pattern
• D. Area of origin

Answer: (A)

This concept is about how the fire leaves visible clues that show both how the materials were burned and the direction the flames traveled from where the fire began. The term that captures this combined appearance—the design of scorch and char patterns on surfaces and the paths those patterns indicate as the fire moved from the origin—is fire pattern. Fire patterns help investigators reconstruct the fire’s travel route, tell where the fire started, and understand how fuel and ventilation influenced spread.

Fire load refers to how much combustible material is available, which affects how long and intensely a fire burns. Vent pattern describes the effects that openings and ventilation have on flame spread and smoke flow. Area of origin is the specific location where the ignition started. Among these, fire pattern is the term that specifically describes the visible design and travel path from the origin.
