Which of the following should be included in the incident timeline?

• A. Key times, locations, and actions taken by responding personnel
• B. Personal opinions about the responders
• C. Irrelevant financial records
• D. Speculation about future incidents

Answer: (A)

An incident timeline is a chronological record of events as they unfold during an incident. It should be factual, precise, and easy to verify. Including key times, locations, and actions taken by responding personnel is essential because it shows exactly how the incident progressed: when responders arrived, where they moved, and what steps they took. This level of detail supports coordination, accountability, and after-action review, and helps align with other records like dispatch logs and radio transmissions. Personal opinions about the responders have no place in the timeline because they introduce bias. Irrelevant financial records and speculation about future incidents also distract from the factual sequence of events and can mislead investigators. Focus on observable, verifiable details: timestamps, locations, and concise descriptions of actions, including who performed them when applicable.
