Comparison of Modern and Legacy Home Furnishings

This demonstration highlights the changes furnishings have had on flashover times.

Effectiveness of Fire Service Vertical Ventilation and Suppression Tactics

UL FSRI is examining the impact of vertical ventilation (through the roof), both naturally induced and as a firefighting tactic, on fire growth behavior in residential structures.

Firefighter Exposure to Smoke Particulates

UL partnered with the Chicago Fire Department and the University of Cincinnati College of Medicine to further investigate the causal relationship between sub-micron smoke particles and the risk of cardiovascular problems.

Firefighter Safety and Photovoltaic Systems

UL examined concerns of photovoltaic (PV) systems and potential impacts on firefighting operations.

Governors Island Experiments

UL has partnered with NIST, FDNY, and GIPEC to conduct townhouse fire experiments to advance firefighter safety.

Impact of Ventilation on Fire Behavior in Legacy and Contemporary Residential Construction

UL examined fire service ventilation practices and the impact changes in modern home geometries have had upon fire behavior.

Improving Fire Safety by Understanding the Fire Performance of Engineered Floor Systems

The main objective of this project was to improve firefighter safety by increasing the level of knowledge on the fire response to basement fires.

Structural Stability of Engineered Lumber in Fire Conditions

UL, in collaboration with the Chicago Fire Department, Michigan State University, and the International Association of Fire Chiefs, completed a fire research study to understand firefighters hazards posed by the use of lightweight construction of wood trusses and engineered lumber in roof and floor designs.

Study of Residential Attic Fire Mitigation Tactics and Exterior Fire Spread Hazards on Fire Fighter Safety

UL FSRI is leading a 2-year study to examine fire service attic fire mitigation tactics and the hazards posed to firefighter safety by the changing modern residential fire environment and construction practices.

Study of the Effectiveness of Fire Service Positive Pressure Ventilation During Fire Attack in Single Family Homes Incorporating Modern Construction Practices

This study will examine the use of PPV during fire attack in modern home geometries and will serve as a comparison to the two previous studies on horizontal and vertical ventilation tactics used by the fire service across the country every day. This project will address the concerns the firefighter community has expressed and provide a baseline for choosing the most appropriate type or types of ventilation on the fire ground. The results and conclusions of this project will be used to improve firefighting tactics, fireground safety and fire dynamics knowledge.
