Arson, Explosion and Fire Investigators

Everything you wanted to know about Arson, Explosion and Fire Investigators

What is an arson and fire investigator?

What's a fire investigator, you ask? Well, they're the folks who put their expert skills in fire science, engineering, and forensic techniques to use to figure out where and how a fire started.

When a fire investigator is called to the scene of a fire, they start by collecting physical evidence like ashes, debris, and burn patterns. They also talk to witnesses, take photos and videos, and work with other first responders like firefighters and police officers. It's like a real-life detective work!

Their goal is to uncover the origin and cause of the fire, and if it was arson, they work with law enforcement to bring the culprits to justice.

So there you have it, a fire investigator is an important part of a fire investigation team, who works hard to unravel the mysteries of fires and explosions

What tools do fire investigators use in their work?

Are you curious about the tools that fire investigators use in their line of work? Well, they use a variety of equipment to help them determine the origin and cause of a fire. Let me tell you about some of the tools they use:

Thermal imaging cameras are pretty cool because they can detect heat signatures. These cameras help investigators identify areas of the fire that were the most intense or identify where the fire may have started.

Fire accelerant detection dogs are also used by fire investigators. These specially trained dogs can sniff out flammable liquids that may have been used to start a fire. That's pretty impressive, right?

Fire investigation case management software helps organize and manage the information collected during an investigation. It makes it easier for investigators to keep track of all the information they need to solve a case.

Measuring and mapping tools like tape measures, rulers, and plumb bobs help fire investigators measure distances and angles at the scene. They may also use mapping software to create diagrams or maps of the area.

Digital cameras are used to capture images of evidence, such as burn patterns or charring. These images are then analyzed to help determine the cause of the fire.

Forensic laboratory equipment is used by fire investigators to analyze samples of evidence, such as soot or debris. This helps them determine the cause of the fire.

What are the main steps of a fire investigation?

There are typically five main steps that investigators follow to try and determine the origin and cause of the fire. Let's take a closer look at each of these steps:

First up is the scene assessment. This is where the investigator arrives on the scene and takes a close look around to identify any potential hazards or sources of ignition. They'll look for things like electrical equipment, flammable liquids, or anything else that could have contributed to the fire.

Next comes evidence collection. The investigator will document any physical evidence from the scene, like burn patterns or the condition of objects. This evidence will be carefully collected and preserved for analysis.

The third step is witness interviews. The investigator will interview anyone who might have information about the fire, like the people who were in the building or first responders. These interviews can be crucial in helping to piece together what happened.

After collecting all of this information, the investigator will move on to analysis. This is where they will look at all of the evidence and information gathered during the investigation to try and determine the origin and cause of the fire. This can involve using specialized tools and techniques to analyze things like burn patterns and the behavior of the fire.

Finally, the investigator will write a report detailing their findings and any recommendations for preventing similar fires in the future. The report can be used to help determine the cause of the fire and, if necessary, bring those responsible to justice.

All in all, fire investigations are a complex process that require a lot of careful attention to detail. The specific steps involved can vary depending on the circumstances, but the ultimate goal is always the same: to determine what happened and why.

What is NAFI?

NAFI? It stands for the National Association of Fire Investigators, and it's a group that's dedicated to helping fire and explosion investigators do their jobs better.

NAFI has been around since 1971, and it's grown to become one of the biggest professional organizations for fire investigators in the world. That's pretty cool, right?

So, what does NAFI actually do? Well, its mission is to give fire investigators the knowledge, skills, and tools they need to conduct thorough and effective investigations. They do this by offering all kinds of resources and services, like training and certification programs, a code of ethics, and professional development opportunities.

But that's not all! NAFI also provides its members with access to networking and professional development events like conferences, workshops, and other events where fire investigators can connect, share knowledge, and learn from each other.

Overall, NAFI is an incredibly valuable resource for fire investigators. With all the support and resources it provides, it helps investigators do their jobs better, solve cases more effectively, and excel in their field.


The International Association of Arson Investigators (IAAI) is an organization that specializes in helping fire and explosion investigators improve their skills and knowledge by offering various certifications and designations.

One of their main certification programs is the IAAI-CFI (Certified Fire Investigator) program, which provides a comprehensive curriculum that covers everything needed to conduct a thorough and effective fire investigation. If you're someone who specializes in investigating explosions, then the CFEI (Certified Fire and Explosion Investigator) program might be the perfect fit for you.

If investigating vehicle fires is your area of interest, then you should check out the CVFI (Certified Vehicle Fire Investigator) program. For those who aspire to teach fire investigation courses, the CFII (Certified Fire Investigator Instructor) program is an excellent choice.

On the other hand, if you're looking to support fire investigators in their investigations, then the IAAI-FIT (Fire Investigator Technician) certification program would be ideal. And if you're interested in conducting basic fire investigations, the IAAI-CI (Certified Fire Investigation Technician) program could be your perfect match.

Lastly, the IAAI-ECT (Evidence Collection Technician) program is for those who want to assist in investigating fire incidents. All in all, these certifications and designations are a great way for fire and explosion investigators to enhance their knowledge, skills, and gain professional development opportunities.

What are the different duties of a fire investigator, fire inspector, fire marshal, fire captain and firefighter?

Fire investigators, fire inspectors, fire marshals, fire captains, and firefighters all have different responsibilities when it comes to promoting fire safety and preventing fires.

Fire investigators are like detectives who determine the origin and cause of a fire. They're trained to use their knowledge of fire science, engineering, and forensic techniques to conduct thorough investigations of fires and explosions.

Fire inspectors, on the other hand, make sure that buildings and structures comply with fire safety codes and regulations. They might inspect buildings, review construction plans, and provide education and training on fire safety.

Fire marshals enforce fire codes and regulations, conduct fire prevention activities, and investigate fires to determine their cause. They might also work with other emergency response agencies in the event of a major fire or disaster

Fire captains are leaders within the fire department who oversee the operations of a specific fire station or group of firefighters. They might supervise and train firefighters, coordinate firefighting efforts, and make operational decisions.

Finally, firefighters are the heroes who respond to fires and other emergency situations. They're trained to fight fires, rescue people from burning buildings, and provide emergency medical care. They might also conduct fire prevention activities, like inspections and education.

So, while all of these roles share a common goal of promoting fire safety and preventing fires, each has its own unique duties and responsibilities.
