What Does a Fire and Arson Investigator Do?
Learn About the Salary, Required Skills, & More
If you've ever seen the result of a house or structure fire, then you know what kind of carnage an arsonist is capable of causing. Fire brings destruction, and it can be devastating to a family or business, even if no one is hurt in the process. To the untrained eye, fires cause total devastation without the slightest trace of evidence. Unless, of course, you're a fire and arson investigator.
Most states and many local governments have established an investigative body to look into incidents of fire and arson. These agencies employ specially trained inspectors and investigators to root out the causes of fires to aid in future prevention and to bring criminals to justice.
Fires present unique challenges to law enforcement professionals and thus require specialized knowledge and training. If you enjoy problem-solving and challenging puzzles and are interested in investigations, chemistry, physics, and fire science, then a job as a fire and arson investigator may be the perfect criminology career for you.
Fire and Arson Investigator Duties & Responsibilities
The job of a fire investigator often includes:
- Responding to and investigating fire scenes
- Identifying and collecting evidence
- Determining whether or not a crime has been committed
- Writing reports
- Identifying potential motives and suspects
- Interviewing witnesses and interrogating suspects
- Arresting suspects
- Working closely with other law enforcement partners
- Providing courtroom testimony
Arson investigators generally do not initiate investigations but respond to requests from fire departments or other law enforcement agencies in the event of suspicious fires or circumstances. They may also work for private corporations, such as insurance companies, to investigate fires in the event it has been determined no crime has occurred.
Fire and arson investigators may spend time working in laboratories and conducting experiments to learn more about how fires start and spread. They also study the effects of accelerants and the type of evidence they may leave, and share that information with other investigators.
Fire and arson investigators are sworn law enforcement officers and work for state law enforcement agencies, police departments or fire departments. They are specially trained to identify and collect evidence relating to fires and make determinations as to their causes. They are also tasked with identifying potential suspects in the event they find that arson has occurred.
Fire inspectors and arson investigators may also inspect structures, homes, and businesses to ensure they meet fire safety standards and regulations to prevent or mitigate the effects of a major fire.
Investigators use a combination of crime scene investigation, interview, and interrogation techniques and knowledge of fire science to inspect scenes. They look for evidence of the use of accelerants, such as gasoline and other flammable materials, and work to identify the source, starting point and spread of fires.

College education: Fire investigator careers are among the many criminal justice careers that do not require a college education. However, in light of the scientific nature of fire investigations, a college education will be quite beneficial, particularly in criminal justice, criminology, and especially fire science or chemistry.
Police academy: Because fire investigators are usually law enforcement officers, job candidates will need to attend a police academy. Some departments may sponsor academy training, while others will require candidates to obtain law enforcement certification prior to being hired. It's always best to check with your individual agency of interest for specific requirements before completing the job application.
Experience: As with other detective and investigator careers, prior law enforcement experience is preferred and may often be required. Also, veteran's preference points are often awarded and candidates with past relevant work experience, education and training will receive preference in hiring. Certifications are available from several fire investigator associations.
Background check: Employment as a fire or arson investigator will also likely require a thorough background investigation. It may include a credit check, criminal history check and perhaps even a psychological and polygraph exam.
Training: Fire departments typically have a classroom section of the program in addition to on-the-job training.

- Critical-thinking skills: Fire inspectors need to recognize code violations and recommend ways to fix the issue, and they must be able to analyze the evidence from a fire and reach a reasonable conclusion.
- Detail oriented: Fire inspectors must pick up on details when they inspect a site for code violations or investigate the cause of a fire.
- Physical strength: Fire investigators may need to move heavy debris out of the way at the site of a fire in order to get a more clear understanding of the scene.
