STOW — State Fire Marshal Peter J. Ostroskey and Massachusetts Firefighting Academy Director David C. Evans are pleased to announce 23 public safety officials completed the Massachusetts Firefighting Academy’s six-day Advanced Fire Investigation course on Friday, May 30, 2019. This rigorous professional training provides public safety professionals with the advanced skills to accurately determine the origin and cause of fires in their jurisdictions and together, build solid, prosecutable cases.
Team Concept of Fire Investigation
State Fire Marshal Ostroskey said, “The team concept of fire investigation has been used successfully in Massachusetts for over 20 years and it starts with joint training.” He added, “When police and fire are trained in the same techniques and procedures together, the consistency leads to accurate origin and cause determinations, and when arson is the cause, solid criminal cases.”
Massachusetts Firefighting Academy Director Evans said, “This course provides students with fire scene experience from investigation through courtroom testimony. They are exposed to the investigatory process as outlined in the National Fire Protection Association Standard 921: Guide for Fire and Explosion Investigations.”
23 Graduates: 17 Firefighters, 1 Local Police Officer, 4 Troopers, 1 State Fire Code Official
The 23 graduates, including one local police officer, 17 firefighters, four State Police troopers and one DFS code compliance officer, represent the following agencies:
- Ashland Fire Department
- DFS-Fire Safety
- Dunstable Fire Department
- Falmouth Fire Department
- Gloucester Fire Department
- Haverhill Fire Department
- Lynn Fire Department

- Northampton Fire Department
- Peabody Fire Department
- Salem Fire Department

The 6-day advanced fire investigation course covers the concepts of fire behavior, scene examination, fire scene documentation, evidence collection, witness interviewing, and management of major fire investigations in more depth than the basic fire investigation class. It also addresses the legal issues of managing fire scenes, evidence collection, and concludes with practical exercises of interviewing witnesses and participating in the courtroom process. Students research and present case briefs on landmark fire investigation cases and scholarly publications. They work with actual assistant district attorneys to prepare their legal cases and participate in a mock trial. The program covers unintentional fires, intentionally set fires, and fatal fires.
Students learn how to effectively collect evidence samples, how and when to avail themselves of resources such as accelerant-detection canines, state police fire investigators in the Office of the State Fire Marshal, and technical experts such as electricians.
Origin and Cause Determination
Fire investigators work first to determine the point of origin of the fire and then its cause. Once they are able to determine where the fire started, they often rely on witness statements to identify the possible sources of ignition at that point and then work to eliminate each possible ignition source, one by one, until they are left with only one most probable cause. Fire investigators are trained to examine a fire scene by going from the minimum amount of burn damage to the point or points with the maximum amount of burn damage. The rationale being that the fire has been burning longest where the most damage is and that is often where the fire began. In addition, they learn to identify fire patterns, which can help investigators determine the intensity and duration of the fire, and the direction in which it spread.
Massachusetts uses a witness-driven protocol of fire investigation. Investigators want to interview people who know the building or saw the fire start as quickly as possible while memories are fresh or before those displaced by the fire become hard to locate. Investigators compare the witness statements to the evidence found in the forensic scene examination to determine the cause of the fire. With possibly a large number of people to interview quickly, the benefit of the added manpower a team investigation brings is clear. Investigators compare notes and often need to re-interview witnesses for clarification. A deep understanding of fire behavior is essential to evaluating witness statements.
Ostroskey said, “It is a challenge to determine the cause of the fire when so much of the needed evidence is destroyed by the fire itself. Fires can also create evidence which assists investigators. This training provides our local fire and police investigators with the skills and knowledge to meet that challenge.”
This course was developed in accordance with NFPA Standard 921: Guide for Fire and Explosion Investigations and NFPA Standard 1033: Professional Qualifications for Fire Investigator.
