This form of fire cause evidence is used to spread the fire from one area of the structure to another or from one floor to another

• A. Trailers
• B. Fire Patterns
• C. Accelerants
• D. Photographs

Answer: (A)

Trailers are burn trails that show the path the fire took as it moved through a structure. They leave evidence along surfaces—such as char, soot, or melted materials—that marks the route the flames and heat followed, helping investigators see how the fire spread from one area to another or from one floor to another. By tracing these trails, you can infer the direction of travel, which rooms were involved, and where the fire likely originated. This type of evidence is distinct from fire patterns (the shapes and geometry of burn), accelerants (substances used to start or intensify the fire), or photographs (documentation of evidence).
