Fire Causation and the Role of a Forensic Engineer

Fires can be caused by a wide range of circumstances: human activity, unique climatic conditions, electrical hazards, and improper storage or handling of flammable materials. To help you narrow down information about the event, we analyze the fire through its four stages: ignition, growth, full development, and decay.

Forensic engineering in fire causation refers to the practice of using engineering principles to analyze a fire scene and determine the most likely cause of a fire by examining physical evidence like burn patterns, damage patterns, material analysis, and electrical systems, with the goal of identifying the ignition source and contributing factors that led to the fire incidentthis information is often crucial for legal proceedings, insurance claims, and preventing future fires.

Key aspects of forensic engineering in fire causation:
  • Analyzing fire patterns:

    Examining the shape, depth, and direction of burn patterns on surfaces to pinpoint the origin of the fire. 

  • Examining electrical systems:

    Inspecting wiring, appliances, and electrical outlets for potential faults or overheating that could have sparked a fire. 

  • Material analysis:

    Identifying the materials present at the fire scene and analyzing how they burned to understand the fire’s progression. 

  • Structural assessment:

    Evaluating damage to building structures to determine the fire’s intensity and potential contributing factors like structural weaknesses. 

Common causes of fires investigated by forensic engineers:
  • Accidental ignition sources: Faulty wiring, overloaded circuits, malfunctioning appliances, open flames, heat sources 
  • Intentional ignition (arson): Deliberate setting of a fire using accelerants 
  • Chemical reactions: Improper storage or handling of flammable chemicals 
  • Combustion issues: Improper fuel-air mixture, malfunctioning fuel systems 
Important considerations in fire causation investigations:
  • Fire dynamics: Understanding how heat, oxygen, and fuel interact to influence fire spread and behavior 
  • Evidence preservation: Properly collecting and documenting physical evidence from the fire scene 
  • Expert testimony: Presenting findings in a clear and concise manner to explain the cause of the fire in legal proceedings 

Uncovering Truth Through Forensic Science

Multidisciplinary Collaboration & Precision

Forensic Engineering plays a crucial role in the investigation of fires and failures. Our engineers are tasked with determining the factors that led to a particular event and providing a defensible opinion based on the facts. As a result, our forensic engineers work closely with the investigation, evidence, and technical service teams to complete multi-disciplined analyses during an investigation. We are ready to provide the expertise and support of our Forensic Engineers through the fire analysis process. Contact Us today to learn how we can help!
