What is a fire department's role in arson investigation?

The role of a fire department in arson investigation primarily involves providing evidence and expertise. Firefighters and investigators are trained to analyze fire scenes, identify potential causes of fire, and look for signs that may indicate arson. They collect physical evidence, such as accelerants or unusual burn patterns, and work with police and forensic teams to determine the circumstances surrounding the fire.

By gathering and analyzing evidence, fire department personnel contribute critical insights that can help law enforcement agencies build a case against possible arsonists. Their expertise in fire behavior, chemistry, and structural integrity makes them essential to the investigative process, aiding in the overall effort to understand the fire's origin and determine if criminal activity occurred.

The other choices reflect roles that are either outside the fire department's responsibilities or do not coincide with the primary function they serve during arson investigations.
