UL Firefighter Safety Research Institute (FSRI) is proud to release the full scientific report and fire service summary report for 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 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 2 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.

This work would not have been possible without the support and dedication of the project technical panel. The 24-member panel, guided UL FSRI through each step of the project. Their tireless work is what makes this research applicable to fire service members world-wide.
