The exigent circumstances rule allows fire investigators to:

• A. Gather evidence without a warrant
• B. Conduct an investigation as long as the integrity of the scene is maintained
• C. Collect evidence only with consent
• D. Delay investigation until the scene is secured

Answer: (B)

Exigent circumstances allow investigators to act quickly when waiting for a warrant could result in the loss of evidence or pose an immediate danger. In a fire scene, that means you can proceed with the investigation without delay to preserve what’s there, but you must take care to keep the scene’s integrity intact—avoid unnecessary disturbance, document conditions as you go, and maintain proper custody of any evidence. This is why the best choice describes conducting the investigation as long as the integrity of the scene is maintained. It isn’t a blanket permission to seize evidence without any constraints, it isn’t limited to consent, and it isn’t about delaying until the scene is fully secured.
