What should a fire investigator always be aware of on a scene?

A fire investigator must always be aware of the possibility of rekindle when assessing a fire scene. Rekindle refers to the potential for a fire that has seemingly been extinguished to reignite, which can occur due to smoldering materials or insufficient cooling of hot spots. This risk is particularly vital for investigators to consider as they conduct their examinations, because failing to recognize this possibility can jeopardize their safety and compromise the integrity of the investigation.

In addition to rekindle, fire investigators pay close attention to the scene for other factors such as hazardous chemicals, the presence of bystanders, and the time of day—all of which can have implications for the safety and thoroughness of the investigation. However, acknowledging the risk of rekindle is crucial for making sure that the environment remains safe during evidence collection and analysis. Being cognizant of this risk ensures that the investigation can proceed without the threat of unexpected dangers arising from the remnants of the fire, allowing the investigator to focus on gathering accurate information and evidence concerning the fire's cause and origin.
