This week, Massachusetts Firefighting Academy instructors delivered the U.S. Fire Administration National Fire Academy's Fire Investigator: First Responders course to students drawn from the fire service and law enforcement. The two-day class gives an entry-level overview of fire chemistry; the first responder's role in fire suppression and fire investigation; and the importance of evidence identification and preservation. It's a prerequisite for the MFA's Fire Investigator program. | Massachuse
