Which term describes the history of the fire, beginning at origin and continuing through the spread?

• A. Exigent Circumstances
• B. Fire Cause
• C. Ignition Sequence
• D. Contamination

Answer: (C)

Ignition sequence describes the history of a fire from origin through its spread. It captures how the fire begins, how fuels ignite, and how heat transfer and ventilation drive progression, outlining the order and pathways the fire follows as it grows and moves through the structure. This makes it the best descriptor of how the fire develops over time. Exigent circumstances deal with emergency actions under time pressure, not the fire’s development; Fire Cause is about why the fire started; Contamination is not related to the fire’s history.
