Time of arrival is considered what type of information to provide to fire investigators?

• A. Essential
• B. Immediate
• C. Additional
• D. Redundant

Answer: (C)

When investigators reconstruct what happened, they rely on data that helps establish the timeline and context, as well as the key facts about where and how the fire started. Time of arrival from responding units adds important context for the incident chronology, helps verify dispatch records, and can reveal delays that might have affected conditions on scene. It does not directly determine the fire’s origin or cause, which are the core investigative questions, so this information is considered additional rather than essential. It’s not redundant, because arrival times can be cross-checked across multiple units and used to corroborate statements and fill gaps in the timeline.
