What is typically the first step after a fire has been extinguished during an investigation?

In fire investigation, after a fire has been extinguished, the initial step is to assess safety and collect evidence. This phase is crucial because investigators must ensure their own safety and the safety of others at the scene before they can accurately begin collecting and analyzing evidence related to the fire. This includes checking for hazards such as structural damage, potential flare-ups, or the presence of hazardous materials.

Once safety is established, investigators can systematically collect evidence that may include observing and documenting the scene, taking photographs, and securing items that might provide insights regarding the cause and origin of the fire. This foundational step lays the groundwork for subsequent investigative actions, such as mapping the area and conducting interviews. By prioritizing safety and evidence collection, investigators can maintain a structured and effective approach to understanding the fire incident.
