This work presents a second-generation phi meter capable of making simultaneous real-time measurements of the global equivalence ratio and combustion product concentrations (i.e., water vapor, carbon dioxide, and oxygen). The fuels initially examined are

A series of time-averaged temperature, velocity, and gas species measurements are made along the centerline of propane fires established on a 37 cm diameter gas burner situated in a quiescent environment. Fires with heat release rates of 20 kW and 34 kW
The COVID-19 pandemic kept people at home, in either a voluntary or non-voluntary capacity, in many countries. These suggested countermeasures were prominent in the so-called initial waves of the pandemic, especially from March 2020 to May 2020. As people
A fire started in Shurijo Seiden, or the main hall of Shurijo Castle, Naha-city, Okinawa, Japan on the morning of October 30th, 2019. The fire resulted in loss of 8 structures and many important Okinawan cultural assets. The original Shurijo Castle was
Over the past few years, the large outdoor fire problem has been a growing concern throughout the world. It is recommended to clear the combustibles around homes and within communities to avoid potential loss of properties, as firebrand shower ignition is

The development of fire prevention and mitigation technologies with a benign toxicological and environmental profile has become of particular interest in the USA due to the recent adoption of state regulations that severely restrict the use of flame

A series of measurements was conducted using a bidirectional probe to characterize the upward speed in the plumes of medium-scale pool fires burning a variety of gaseous and liquid fuels. Time-averaged local measurements of the upward velocity were

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
