What Does an Arson and Fire Investigator Do?

An Arson and Fire Investigator is a highly specialized professional tasked with determining the origin and cause of fires and explosions. They are, in essence, forensic detectives of the fire world. Their work is a critical component of both public safety and the justice system, as their findings can lead to improved fire codes, product recalls, and the criminal prosecution of arsonists.
The role is far more complex than simply arriving at a fire scene. It requires a deep understanding of fire science, chemistry, electrical engineering, building construction, and legal procedures. Investigators must operate under a strict scientific method, meticulously documenting every step of their process to ensure their conclusions can withstand intense scrutiny in a court of law.
Core Responsibilities and Daily Tasks:
- Scene Examination: The primary task is the methodical and systematic examination of the fire scene. This involves identifying the fire's point of origin by analyzing fire patterns (like V-patterns), char depth, and the effects of heat and smoke on different materials.
- Evidence Collection and Preservation: Investigators identify, document, photograph, and collect physical evidence that may indicate how a fire started. This can include anything from melted wiring and malfunctioning appliances to traces of accelerants (like gasoline) or components of an incendiary device. Maintaining a strict chain of custody for all evidence is paramount.
- Witness Interviews: They conduct interviews with firefighters, first responders, property owners, and any potential witnesses to gather information about the fire's behavior, any unusual circumstances observed, and the activities of people before the fire started.
- Research and Analysis: The investigation extends beyond the scene. It may involve researching the history of the property, the financial status of the owners, and the technical specifications of any appliances or systems suspected of causing the fire.
- Report Writing: One of the most critical and time-consuming tasks is compiling detailed, objective, and scientifically-sound reports. These documents outline the investigator's entire process, from initial observations to final conclusions, and serve as the official record of the investigation.
- Court Testimony: Investigators are often called to testify in both civil and criminal court as expert witnesses. They must clearly and confidently present their findings to a judge and jury, explaining complex scientific principles in an understandable way.
- Collaboration: They work closely with a wide range of professionals, including fire departments, police detectives, prosecutors, insurance adjusters, and engineers.
### A Day in the Life of a Fire Investigator
7:00 AM: The day begins at the office, catching up on paperwork from an ongoing case involving a suspicious warehouse fire. You review lab results that just came back, confirming the presence of a specific chemical accelerant in several debris samples. This is a significant breakthrough.
8:30 AM: The dispatch pager goes off. A residential structure fire from overnight has been flagged for investigation. The fire is out, but the battalion chief on scene noted some unusual fire spread patterns that couldn't be immediately explained.
9:15 AM: You arrive at the scene. The smell of smoke and wet ash hangs heavy in the air. After donning your personal protective equipment (PPE)—turnout gear, a helmet, respirator, and steel-toed boots—you meet with the incident commander for a briefing.
9:45 AM - 2:30 PM: The methodical scene investigation begins. You start from the area of least damage and work your way toward the most heavily burned section, a process known as the "reverse progression" of the fire. You photograph everything, create detailed sketches and diagrams of the structure, and take measurements. You identify a clear point of origin in the living room and meticulously excavate the area, layer by layer. You discover the remains of a timing device and some wiring that doesn't belong to the home's electrical system. You carefully collect these items, along with control samples, placing them in evidence containers.
2:30 PM: You take a break to interview a neighbor who called 911. They mention seeing an unfamiliar car speeding away from the house just minutes before they saw smoke. You take detailed notes.
3:30 PM: Back at the office, you properly log and secure the evidence collected from the scene, initiating the chain-of-custody paperwork. You begin drafting your preliminary report, outlining your initial findings and the evidence recovered.
4:30 PM: You collaborate with a police detective assigned to the case, sharing your findings about the potential incendiary device and the witness statement. The case has now officially transitioned from an undetermined fire to a criminal arson investigation. Your work today has laid the foundation for the entire criminal case to follow. The day ends not with a final resolution, but with a clear path forward in the pursuit of answers.

### Beyond the Base Salary: A Look at Total Compensation
The annual salary is only one part of the financial picture for a fire investigator. The total compensation package is often a significant draw, especially in the public sector.
- Overtime Pay: Fire investigation is not a 9-to-5 job. Investigators are on call and frequently work long, irregular hours at scenes, leading to substantial overtime pay, which can increase annual earnings by 10-25% or more.
- Bonuses and Special Pay: Some public departments offer "certification pay" or "assignment pay"—a stipend for holding specific qualifications (like a CFI®) or being part of a specialized unit. In the private sector, particularly insurance, investigators may be eligible for performance-based bonuses tied to case closures or fraud identification.
- Retirement and Pension Plans: This is a major advantage of public-sector employment. Many municipal, state, and federal investigators are enrolled in defined-benefit pension plans, which provide a guaranteed income after retirement based on years of service and final salary. This is a benefit of immense long-term value that is rare in the private sector.
- Health and Insurance Benefits: Government agencies and large private firms typically offer comprehensive health, dental, vision, and life insurance packages with lower employee premium contributions than smaller companies.
- Allowances and Provided Equipment: It is common for investigators to receive a clothing or uniform allowance, a take-home vehicle (a significant financial benefit), and all necessary specialized equipment, from cameras and forensic tools to laptops and mobile phones.
When evaluating a job offer, it's essential to look beyond the base salary and consider the total value of the compensation and benefits package, as it can dramatically impact an investigator's overall financial well-being.
