Exhaust flow measurements have been found to be a significant source of uncertainty for measurements of heat release rate in large-scale fire experiments. Asymmetric or skewed velocity distributions are often present in the exhaust ducts for open

An analysis of oxygen concentration measurements is conducted to investigate compartment ventilation before a potential backdraft phenomenon. Experiments are performed in a 2/5th scale compartment of varying configurations such as fuel flow time, spark

In the last twenty years, wildland-urban interface (WUI) fires have been growing in severity and size. The structures destroyed by WUI fires have devastated entire communities and have cost billions of dollars while significantly impacting the social
This report documents the design and performance of a second-generation phi meter used in multi-scale experimental applications. A constructed second-generation phi meter is implemented in bench and 2/5th scale experiments to demonstrate the instrument's
In our previous work, the fire performance of seven upholstery materials combinations - including six barrier fabrics, one cover fabric and one flexible polyurethane foam - was assessed by (1) full-scale chair mock-up tests and (2) a newly developed bench

A generic graph neural network-based model is developed to predict the potential occurrence of flashover for different building structures. The proposed model transforms multivariate temperature data into graph-structure data. Utilizing graph convolution

PRIMARY AUDIENCE Fire protection and fire probabilistic risk assessment engineers conducting or reviewing fire modeling that supports fire probabilistic risk assessments related to characteristics (e.g., ignition, fire growth, and peak heat release rate)
Casualties in fires--and in particular, deaths--are tail events. The average fire does not cause deaths or injuries. There is increasing evidence that the people susceptible to dying in fires are a specific subset of the people in homes. It seems likely

The purpose of this paper is to report the first of four planned fire experiments on the 9.1 m × 6.1 m steel composite floor assembly as part of the two-story steel framed building constructed at the National Fire Research Laboratory. This paper presents

It can be assumed that smoke alarms reduce reported fires and casualties by reducing on average the amount of time it takes to detect a fire. This paper sets out to determine by how much that detection time is reduced. It does so by comparing the effect of

A series of fire experiments are being conducted on the 2-story steel framed building with composite floors in the National Fire Research Laboratory. This paper presents a brief overview of experimental design and discusses some results of the first test

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

According to a recent NFPA report, 49 % of reported home fires involve cooking equipment, with cooktops accounting for 87 % of cooking-fire deaths and 80 % of the civilian injuries [1, 2]. Between 2014–2018, U.S. fire departments responded to an estimated

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 '
The accuracy of the exhaust flow measurement contributes significantly to the uncertainty of calorimetry measurements for large fire testing. Less than ideal flow characteristics such as skewed velocity distributions are typical of these largescale flows

Cooking equipment is involved in nearly half of home fires in the United States, with cooktop fires the leading cause of deaths and injuries in cooking-related fires. In this study, we evaluate 16 electrochemical, optical, temperature and humidity sensors

In our previous study, an innovative method for sterilization, inertization, and valorization of organic fraction of the municipal solid waste (OFMSW), to be recycled in the production of composite panels, had been developed. In this follow-up work, the

Fire fighter fatalities and injuries in the U.S. remain too high and fire fighting too hazardous. Until now, fire fighters rely only on their experience to avoid life-threatening fire events, such as flashover. In this paper, we describe the development of

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

In this work, we investigated fire growth in a furnished compartment intended to mimic a living room where a couch was the main fuel load. Three TB-117-2013 compliant and commercially available couches were procured. The couches were identical except for

Effective July 1, 2007, the U.S. Consumer Product Safety Commission promulgated a standard to severely reduce the heat release rate and the early heat output from mattresses and foundations when ignited by a flaming ignition source. This study estimates

Regulations for cigarette ignition resistance (CIR) of soft furnishings (beds and upholstered furniture) and less fire-prone cigarettes have contributed substantially to the decrease in losses from cigarette-initiated fires over time. Two Standard
