Fire investigators examine fire scenes after the fire is extinguished in order to determine the origin of the fire. In addition to having fire fighting experience, they also often pursue associate's degrees in fire science technology and receive training from the National Fire Academy and the International Association of Arson Investigators. Professional certification is available to those who meet the experience and education requirements and pass an exam.

Essential Information

Fire investigators examine fire scenes after they're extinguished to establish the fire's cause and origin. They may question witnesses, gather evidence and document fire scenes. Their findings are often used in arson or criminal cases. Many fire investigators begin their careers as firefighters then advance to investigative positions.

Many aspiring fire investigators obtain training through the National Fire Academy (NFA), which offers various training courses for all government sectors at its Maryland campus. The NFA's course in fire and arson origins and causes is a 10-day program that equips trainees with the technical and scientific skills to conduct fire investigations. The curriculum covers fire physics, electrical and vehicle fires, scene documentation and interrogation techniques among other topics. Trainees also gain hands-on instruction by participating in real-life, fire investigations.

Formal Education

Those interested in becoming fire investigators may also benefit from earning formal education in fire science or engineering. Associate of Applied Science in Fire Science Technology programs are designed for students pursuing advancement in the fire service profession. Courses may include fire prevention principles, investigation methods, fire fighting tactics, emergency medical technician training, fire service administration and legal issues.

Professional Certification

Many fire investigators demonstrate professional competency by earning certification. The IAAI offers the Certified Fire Investigator (CFI) designation to applicants with at least 150 education, training and experience points ( They must prove eligibility by providing diplomas, transcripts, letters of testimony and proof of work history.
