About The Project
Knowledge of fire dynamics is critical for fire investigators to properly identify a fire’s origin. Fire dynamics depend on the relationship of the fuel, heat, and ventilation during a fire event. A ventilation change as simple as a door left open by an occupant fleeing the fire, a window open remote from the fire, or a window that fails as a result of fire growth could greatly impact the fire damage inside the structure. UL Firefighter Safety Research Institutes's (FSRI) fire investigation project completed scientific research into how ventilation impacted fire patterns and electrical system damage in single-family homes.
During the past decade, research conducted for the purpose of examining firefighting tactics has brought focus to the impact that on-going changes in home construction materials, contents, size, and geometry have on a fire incident. Current residential structure fires are predominantly fueled by synthetic contents and commonly become ventilation-limited. How and where the fire receives oxygen, especially with a ventilation-limited fire, impacts the fire growth. This project explores both the subsequent fire damage patterns and exposure of energized electrical cords.
This project was supported by Award No. 2015-DN-BX-K052, awarded by the National Institute of Justice, Office of Justice Programs, U.S. Department of Justice.

UL FSRI assembled a technical panel of national fire investigation experts that represent a range of forensic specialties in both the public, private, academic, and research sectors.Click here to see the project technical panel.
