Who typically performs fire cause determination in large departments?

• A. By primary investigator
• B. By external consultants
• C. By delegation
• D. By committees

Answer: (C)

In large fire departments, fire cause determination is typically performed by delegation to a trained investigator or a dedicated fire investigation unit within the department. This setup ensures that someone with specialized training handles the investigation, uses consistent methods, collects evidence properly, interviews witnesses, and documents findings in a standardized way. It also keeps the workload manageable by distributing cases across a qualified team rather than relying on a single person or an ad hoc group. External consultants might be brought in for particularly complex cases, but the routine, organized approach is to assign the task to internal investigators who have the authority and accountability to complete the determination. Committees tend to be slower and less practical for on-scene or timely investigations, which is why delegation to an internal, trained unit is the typical practice.
