This document provides documentation for creating and running Monte Carlo simulations with the Consolidated Fire And Smoke Transport (CFAST) model using the CFAST Fire Data Generator (CData). The method follows the general framework set forth in the '
Devastating large outdoor fires have been responsible for destruction of vast amounts of infrastructure and loss of human life. Wildland fires that spread into urban areas, known as wildland-urban interface (WUI) fires, are capable of enormous destruction
Wildland fires that spread into urban areas, termed wildland-urban interface (WUI) fires, are becoming more and more common across multiple locations of the world. An important component in rapid spread of large outdoor fires is the production or

The primary objective of this project is to assess structure-to-structure fire spread for structures located in the Wildland Urban Interface (WUI). Full-scale fire experiments will be conducted in which various types of structures (sources of fire) will be

The 2020 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through four separate lenses

The Camp Fire ignited on November 8, 2018 in the foothills of the Sierra Nevada in Butte County, California. The first 24 hours were characterized by a fast-moving fire with initial spread driven by high winds up to 22 m/s (50 mi/h) and long-range spotting
Wind plays an important role in the built environment. Large outdoor fires in the built environment are no exception. Under strong wind, firebrands fly far, which leads to quick fire spread. In this study, the effect of structure to structure separation

A series of experiments was conducted to investigate the pre-combustion and combustion properties of corn oil heated in pans from 10 cm to 26 cm diameter by a residential electric- coil element cooktop. For comparison, torch-ignited gasoline, heptane and

Two virtual workshops 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), were held this past August (2020). The first session was held

The fire blocking performance of barrier fabrics laminated to upholstery materials was investigated. The results are two-fold. The first involves information gathered directly from cone calorimetry tests conducted on foam/fabric composites to better

The extinguishment processes of cup-burner flames by adding a halon-replacement fire-extinguishing agent C6F12O (Novec 1230) to coflowing air in normal gravity have been studied computationally and experimentally. The time-dependent, axisymmetric numerical
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
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
Studies of human behavior during emergencies have observed that when presented with situational cues that a hazard may be present, humans can fail to act on this information in a timely manner. Models of human behavior in response to fire-related

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
