Thermal imaging cameras (TIC) are becoming an important tool for many firefighters and other first responders. However, due to the lack of performance standards for TIC, a wide variety of designs and capabilities are provided to end users with little
All combustibles produce heat and smoke that, in sufficiently high concentration, may be hazardous to life safety. Incapacitation can result from exposure to the asphyxiant gases, irritant gases, and heat. Irritant gases and visible smoke can reduce a

This paper examines smoke control and occupant evacuation in WTC 1 and WTC 2 on September 11, 2001focusing on the impact region and above for each tower. Approximately 2,000 individuals were at or above the area of impact in WTC 1 and WTC 2 who did not

Some of the most effective flame inhibitors ever found are metallic compounds. Their effectiveness, however, drops off rapidly with an increase of agent concentration, and varies widely with flame type. Iron pentacarbonyl, for example, can be up to two
From inception to completion, software development projects need structure and organization so that good quality, user-friendly software is produced on time and within budget. The structured approach presented in this paper will help you achieve those

The present paper discusses the results of a multiple laboratory test program aimed at determining the consistency of large scale furnace testing. The North American Fire Testing Laboratories Consortium (NAFTL) organized a multiple laboratory test program
Cameras are often used for visual servoing or realtime mapping of the external environment in both autonomous and teleoperated tasks with a dexterous manipulator. Nominal operations will likely produce manipulator configurations that occlude the line-of
As the usage of pervious concrete continues to increase dramatically, a better understanding of the linkages between microstructure, transport properties, and durability will assist suppliers in mixture proportioning and design. This paper presents various
During the past year, the National Institute of Standards and Technology (NIST) has continued work on many projects and started a few new efforts to improve firefighter safety. In addition to the research projects listed below, the Fire Fighting Technology
Although the number of Christmas tree fires is low, the fires carry a higher level of hazard than other fires that occur in a residential structure. This study, supported by the U. S. Fire Administration, has the following three objectives: 1) characterize

A unique experimental apparatus has been constructed in order to generate a controlled and repeatable size and mass distribution of glowing firebrands. The present study reports on a series of experiments conducted in order to characterize the performance
CFAST is a two-zone fire model used to calculate the evolving distribution of smoke, fire gases and temperature throughout compartments of a constructed facility during a fire. The modeling equations used in CFAST take the mathematical form of an initial

Recent investigations demonstrated that the processes of hydrating tricalcium silicate pastes are made favorable by the addition of certain quantities of dicalcium silicate. Optimization of these processes was reflected in the increased compressive
A simple thermal model to predict the failure of electrical power, instrument, and control cables is described. The model is intended as a subroutine for deterministic fire models, and it is of comparable accuracy and simplicity to the activation
As part of an effort to develop standard test methods for the performance of commercial hydrogen sensors, we employed the Fire Emulator / Detector Evaluator, an instrumented flow system designed to study the response of fire detectors (smoke, heat, gas)

Police, firefighters, and emergency medical personnel are some of the first responders that are utilizing thermal imaging cameras in a very practical way every day. However, few performance metrics have been developed to assist first responders in

A series of real scale fire experiments were performed to determine the size and mass distribution of firebrands generated from Douglas Fir (Pseudotsuga menziesii) trees. The results of the real scale fire experiments were used to determine firebrand sizes
Accurate heat release rate measurements provide essential information to defining the fire safety characteristics of products. The size, complexity, and cost of full-scale fire tests make achieving accurate and quantitative results a serious challenge. A
The use of thermal imaging cameras (TIC) by the fire service is increasing as firefighters become more aware of the value of these tools. The National Fire Protection Association (NFPA) is currently developing a consensus standard for design and
