During an origin and cause investigation, which items should be photographed and documented?

• A. The origin only
• B. All of the above
• C. The cause only
• D. None of the above

Answer: (B)

When documenting an origin and cause investigation, you aim to preserve a complete record that covers both where the incident began and what contributed to it. Photographing and noting all items related to the origin and to the cause ensures you have a full, objective view of the scene. This includes the origin point itself, surrounding evidence, equipment, materials, and any patterns or indicators of ignition or contributing conditions. A thorough record supports accurate reconstruction of events, helps verify findings, and maintains the integrity of evidence for any regulatory or legal review. Focusing only on the origin misses important context about what caused the event, while focusing only on the cause misses where it started. That’s why documenting everything relevant to both aspects is the best approach.
