Which concept regarding physical evidence and the fire scene is NOT the sole responsibility of the fire investigator?

• A. Documentation
• B. Evaluation
• C. Reconstruction
• D. Preservation

Answer: (D)

The key idea is that safeguarding physical evidence at a fire scene is a shared duty, not something one person does alone. Documentation, evaluation, and reconstruction are activities that the fire investigator typically leads: documenting the scene with notes, photos, and sketches; evaluating the evidence to understand its relevance to origin and cause; and reconstructing the sequence of events to explain how the fire progressed. Preservation, on the other hand, involves protecting the scene and evidence from contamination, alteration, or loss, and this requires cooperation from multiple parties—responders, law enforcement, building owners, and others who may access the scene. While the investigator initiates and oversees preservation, it isn’t solely their responsibility.
