Smoldering poses a severe fire hazard due to the potentially lethal amount of toxic carbon monoxide released, and the possibility to reach flashover (through transition from smoldering to flaming) with heat sources otherwise too weak to directly induce
Bulk oxide determinations from a pair of portland cements provides the basis for calculation precision and accuracy values for X-ray fluorescence (XRF) analysis for both the fused glass bead and the pressed powder sample preparation. Approximately 45

The developers of egress models are in a difficult position. It is in their interest to develop models that are quick and easy to employ and at the same time to reduce accidental model misuse. While default values enables out-of-the-box use of models
This document provides specific detailed guidance and recommendations on the use of emergency stair travel devices, or stair descent devices, for evacuation of persons with mobility impairments during fire emergencies in buildings. The people who would

To date, there is no International standard on the methods and tests to assess the verification and validation (V&V) of building fire evacuation models, i.e., model testers adopt inconsistent procedures or tests designed for other model uses. For instance
Many aspects of indoor environmental quality (IEQ) and the technologies that control or otherwise affect it are interactive and often closely connected. This has important implications for the design and construction of buildings as well as for operation

The purpose of fire blocking barrier materials is to reduce the flammability of soft furnishings ( mattresses and upholstered furniture) by preventing or delaying direct flame impingement from open flames and/or heat transfer from smoldering ignition
An experimental apparatus, known as the NIST full scale continuous feed Firebrand Generator (the NIST continuous feed Dragon) is presented. The experiment device presented in this paper is a scaled up version of the recently developed bench scale

This exploratory set of experiments investigated the impact of external exposure temperatures on Self Contained Breathing Apparatus (SCBA) supply air, and the potential for the supply air to be heated when it is subjected to an elevated temperature
This report documents the second phase of a multi-year program called CHRISTIFIRE (Cable Heat Release, Ignition, and Spread in Tray Installations during Fire). The overall goal of the program is to quantify the burning characteristics of grouped electrical

The study of compressed hydrogen release from high-pressure storage systems has practical application for hydrogen and fuel cell technologies. Such releases may occur either due to accidental damage to a storage tank or connecting piping, or due to failure
Current design approaches to assess the lateral torsional buckling capacity of steel beams in fire are based on the assumption of uniform steel temperature. This paper investigates the effect of temperature gradients on the lateral torsional buckling
This article identifies research needs in automotive fire protection. The work focuses on the problem of post-collision vehicle fires. Recent fire suppression research is cited with special attention given to results cited in the literature as well as
