Structural Fire Research

On April 12, 2015, a South Dakota firefighter lost their life in a residential structure fire. The first firefighters arrived on scene with reports of a person trapped in the bedroom. When they forced the front door, they experienced thick,…
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 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…
Compartment fire dynamics are very complex with seemingly random behavior. To better understand and predict fire dynamics and smoke spread, there is much to be learned from the results of fire research. Often, we get these results through partial or…
The effects of a compartment fire on a real fire ground is seldom isolated to a single room. In Sweden, for example, over one-third of fire fatalities in apartments are in a room other than the origin room, but in…
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…
Firefighting crew staffing size, alarm response size, and alarm response time are affected by many factors including funding and resource availability, and in turn effect the tactics and outcome at a fire. These companion projects from NIST used field experiments…
This paper from SP Fire Research provides an analysis of the fire behavior in a series of train carriage fire tests. The tests were carried out in three different scale models. In particular, the tests studied different interior materials and…
Understanding compartment fire behavior is key to effective fire safety design and firefighting in buildings. Fire behavior in buildings depends on the properties of the combustibles. This report uses a full-scale model of a residential bedroom to investigate the combustible…
Home fires continue to account for a majority of structural fire deaths, and the bedroom is the most common origin for fatal fires1. This paper details the results of real-scale bedroom fire tests for two realistic scenarios: one with the…
