Final Report Released on Positive Pressure Ventilation and Positive Pressure Attack
The UL Firefighter Safety Research Institute (UL FSRI) published its report on the Study of the Effectiveness of Fire Service Positive Pressure Ventilation During Fire Attack in Single Family Homes Incorporating Modern Construction Practices.
This work was performed by UL FSRI as part of a research study funded by the Department of Homeland Security’s Assistance to Firefighters Grant Program. The full scientific report provides the fire service with scientific data to further understand a tool and tactic that has been in use for over 30 years. It includes an outline of the entire project, a detailed description of the results from the two compartment burns, 24 cold flow experiments, 25 full scale fire experiments and two smoke exhaust experiments along with the tactical considerations. The tactical considerations, developed by the project technical panel, provide concepts to enhance the understanding of how positive pressure attack and positive pressure ventilation affect the fire dynamics in a residential structure.
The accompanying fire service summary report provides a condensed overview of the project along with all of the same tactical considerations found in the full scientific report.
