Which action might you be requested to perform by a fire investigator?

• A. Interview witnesses at a fire scene
• B. Collect chemical samples at a fire scene
• C. Keep a log of persons entering a fire scene
• D. Measure the depth of char near the point of origin

Answer: (C)

Keeping a log of everyone entering and leaving a fire scene is a key duty that supports safety and the integrity of the investigation. When a fire investigator is on scene, knowing who has access and when helps prevent contamination of evidence and ensures accountability. The log provides a clear timeline of activity, which can be crucial for reconstructing what happened and for contact if anyone needs to be interviewed or if there are questions about who handled what materials. While interviewing witnesses, collecting chemical samples, or measuring char depth can occur, those tasks are typically handled by investigators or specialists rather than by the frontline crew. The log is the practical, routinely requested action you would be asked to perform to keep the scene organized and credible.
