Ventilation Research

Underwriter Laboratories (UL) Firefighter Safety Research Institute (FSRI) completed a series of experiments adding to their wealth of information to evaluate how firefighting tactics effect fire behavior, firefighters, and building occupants. The purpose of the study is to improve fire…
Underwriter Laboratories (UL) Firefighter Safety Research Institute completed a series of experiments to evaluate positive pressure ventilation (PPV) during fire attack and to provide the fire service with scientific knowledge of the effects of PPV tactics. The series of experiments…
Full-scale, live-fire experiments provide excellent results, but they are very expensive and time consuming. This report from SP Fire Research in Sweden examines a method to model train carriage fires using CFD (computational fluid dynamics) computer simulations. An accurate simulation…
Modern home construction, layouts, and furnishings have changed the way that fires develop. The Instituut Fysieke Veiligheid (Institute for Safety) and Brandweeracademie (Dutch National Fire Service Academy) in the Netherlands have compiled this report, ‘It Depends’ - Descriptive Research into…
Over the past two decades The Netherlands have experienced a number of line-of-duty deaths. One such incident in 2008 claimed the lives of three firefighters when they were caught by a sudden fire spread in a hangar. Investigations determined that…
Underwriter Laboratories (UL) Firefighter Safety Research Institute has worked with Firehouse Magazine and BullEx to produce a free, interactive training program on tactical fireground considerations based on nearly a decade of research. UL has been researching topics such as building…
While there is much great information generated from firefighter experience and fire research, this information cannot be effectively used by firefighters until it is fully understood. This article from Fire Fighting in Canada provides an excellent explanation of the differences…
Traditionally, buildings were constructed with compartmentalization to help reduce fire spread. Research into this building style resulted in the compartment fire framework, used to describe the fire dynamics in a typical “compartment”. However, modern building have deviated from the traditional…
Underwriter Laboratories (UL) Firefighter Safety Research Institute recently completed a series of experiments to evaluate tactics for fighting exterior and attic fires, and to provide the fire service with scientific knowledge of the dynamics of these fires and the effects…
Fire spread throughout a building is influenced by factors including geometry, fire size, and ventilation. This project from Kyoto University in Japan seeks to create a mathematical method to model the fire spread between rooms. To validate the work, the…
