What is one key aspect of conducting a thorough fire investigation?

One key aspect of conducting a thorough fire investigation is considering all potential sources and factors. This approach ensures that the investigation is comprehensive and unbiased, allowing the investigator to identify various elements such as ignition sources, fuel materials, the environment, and any relevant human factors. By analyzing these components, investigators can form a complete picture of the circumstances surrounding the fire incident.

Incorporating multiple sources of information, including witness accounts, historical data, and physical evidence, contributes to building a solid case and can lead to more accurate conclusions. This consideration of a wide range of factors aligns with the principles outlined in NFPA 921, which emphasizes the importance of a systematic and methodical approach to fire investigation. Such thoroughness is essential to prevent oversight and to establish the cause and origin of the fire accurately.
