Which post-incident activity involves scene security and preserving physical evidence?

• A. Crowd control
• B. Salvage and overhaul
• C. Post-incident critique
• D. Initial fire investigation

Answer: (D)

Securing the scene and preserving physical evidence are essential to determine where a fire started and what caused it. The post-incident activity that centers on this is the initial fire investigation. Investigators work to limit access to the scene, prevent tampering, and protect materials that could show ignition sources, accelerants, or other clues. They document conditions, photograph the scene, collect samples, and maintain a clear chain of custody so results are reliable and usable in analysis or legal proceedings. Other activities, like crowd control, salvage and overhaul, or post-incident critique, focus on safety, property protection, or learning from the response, and do not prioritize maintaining scene integrity for investigation.
