What is the main responsibility of a Fire Investigator at a fire scene?

The main responsibility of a Fire Investigator at a fire scene is to investigate the cause of a fire. This involves collecting evidence, interviewing witnesses, and analyzing fire patterns to determine why the fire occurred and how it spread. The Fire Investigator plays a crucial role in understanding fire behavior, which can help in fire prevention efforts and in prosecuting arson cases if applicable. This work is essential not only for community safety but also for improving firefighting techniques and protocols based on findings from previous fire incidents.

The other roles mentioned, such as educating the public about fire safety, responding to emergency calls, and repairing fire and EMS vehicles, are important duties within the fire service, but they fall under different job descriptions and do not specifically relate to the investigative aspect of understanding fire causes and origins.
