A series of measurements was made to characterize the structure of a 1 m diameter methyl 12 alcohol (methanol; CH3OH) pool fire steadily burning with a constant lip height in a quiescent 13 environment. Time-averaged local measurements of gas-phase
Roof assemblies are known to be vulnerable to firebrands in urban and wildland-urban interface fires. In the 2016 urban fire in Japan (Itoigawa-City Fire), at least 10 structures were ignited by firebrand showers and three of these structures were ignited
A lump-capacitance heat transfer model was developed to model the operation of a slug calorimeter constructed of metal with a Curie point. The resulting formula has been successfully used to infer total heat flux to a metal structural member in a fire by

Polydopamine coatings containing additional bioderived flame retardants were used as coatings for polyurethane foam and cardboard. The ability to form intumescing coatings was crucial for achieving good flame protection. Dopamine can effectively
A simple laboratory-scale experimental method was developed to study firebrand generation processes. As part of these experiments, Japanese wind facilities were used to elucidate the effect of wind speed on the firebrand generation. It was found that very

Hybrid fire testing is a new technique (under development) to performing fire test. It was inspired from subtructuring method and assumes testing individual structural members, as during standard fire testing, which communicate with the analytical

Seven National Metrology Institutes (NMIs) from France, United States, United Kingdom, Russia, Mexico, China and Germany participated in an inter-laboratory comparison on thermal conductivity measurements by the Guarded Hot Plate method. This action was
A shared feature in the rapid spread of large outdoor fires are the production or generation of new, far smaller combustible fragments from the original fire source referred to as firebrands. A simplified experimental protocol has been developed that
Fire spread occurs via radiation, flame contact, and firebrands. While firebrand showers are known to be a cause of spot fires which ignite fuels far from the main fire front, in the case of short distance spot fires, radiation from the main fire may play
As part of recent building code change discussions, it has been suggested that by increasing the spacing of boards, it may be possible to mitigate ignition of wood decking assemblies from wind-driven firebrand showers. An experimental series was undertaken

This paper presents a basis for designing the ASTM E119 fire environment in a large compartment of about 10 m wide, 7 m deep and 3.8 m high constructed in the National Fire Research Laboratory of the National Institute of Standards and Technology. Using

This report presents the experimental investigation of a test fire in a large compartment of about 10 m wide, 7 m deep and 3.8 m high constructed in the National Fire Research Laboratory of the National Institute of Standards and Technology. The test fire
The National Institute of Standards and Technology (NIST) has previously demonstrated that, despite assumptions to the contrary, typical modern commercial building envelopes are not particularly airtight, resulting in significant energy costs. It has also

Large outdoor fires are an increasing danger to the built environment. Wildfires that spread into com- munities, labeled as Wildland-Urban Interface (WUI) fires, are an example of large outdoor fires. Other examples of large outdoor fires are urban fires

The use of halons for fire fighting is being phased out due to their deleterious effects on stratospheric ozone. This paper describes the findings of part of a study designed to characterize and identify super-effective thermal fire-fighting agents as

This paper presents the development of a thin filament pyrometry method to characterize the time- varying temperature field in a medium-scale pool fire in a quiescent environment. A digital camera with optical filters and zoom lens was used to record the

A workshop of the permanent working group, sponsored by the International Association for Fire Safety Science (IAFSS), entitled Large Outdoor Fires and the Built Environment(LOF&BE) was held from 2:00 pm to 4:00 pm on Sunday June 30, 2019. The workshop was
This study reports on the change in flammability of cotton fabrics caused by water-insoluble gel coatings applied from a single bath solution formulated with polymeric micelles and flame retardant amphiphiles. The flame resistant coatings are made from low
Several series of measurements were made to characterize medium-scale pool fires steadily burning in a well-ventilated, quiescent, open environment. Time-averaged local measurements of radiative and total heat flux were made in steadily burning methyl
Experiments were conducted using mock-ups of full-scale roofing assemblies to determine if any insight into firebrand generation from real-scale structures as well as actual urban and wildland-urban interface (WUI) fires was possible using simpler
Firebrands are produced from combustion of both vegetative and structural fuels in large outdoor fires. It is well known that firebrand generation, transport, and ignition mechanisms result in rapid and potentially devastating fire spread processes in

There are a variety of fire protection technologies that have the potential to improve life safety in residences including barrier fabrics for upholstered furniture, new nano-scaled flame retardants, or better fire detector technology. However, there is no
