Mathematical Modeling of Wildland-Urban Interface Fires

June 1, 2011
Author(s)
Randall J. McDermott, Ronald Rehm
This paper presents a simple model to demonstrate the effect on grass-fire propagation of the winds induced by structural fires in a Wildland-Urban Interface (WUI) setting. The model combines an empirical formula for wind-driven grass-fire spread and a

EXPOSING GLAZING ASSEMBLIES TO FIREBRAND SHOWERS

May 16, 2011
Author(s)
Samuel L. Manzello, Sayaka S. Suzuki, Yoshihiko Hayashi
An experimental campaign was undertaken to determine vulnerabilities of glazing assemblies to firebrand bombardment using the NIST Dragon installed in the Building Research Institute’s Fire Research Wind Tunnel Facility (FRWTF). Results of these

PROCEEDINGS OF THE NATIONAL FIRE SERVICE DATA SUMMIT

May 9, 2011
Author(s)
Jason D. Averill, Lori Moore-Merrell, Kathy Notarianni, Robert Santos, Doug Wissoker
Effectively managing a fire department requires an understanding of and an ability to demonstrate how changes to resources will affect community outcomes. It is imperative that fire department leaders, as well as political decision makers, know how fire

Assessing the shelf-life of a prototype reference material for product emissions testing

May 2, 2011
Author(s)
Cynthia H. Reed, Daniel V. Samarov, Dennis D. Leber, Zhe Liu, John Little
The National Institute of Standards and Technology (NIST) and Virginia Tech (VT) are developing a volatile organic compound (VOC) reference material to validate product emissions chamber testing. To verify the storage method of the material and determine

Inter-laboratory study approach to validate the performance of a prototype reference material for product emissions testing

May 2, 2011
Author(s)
Cynthia H. Reed, Andrew K. Persily, Zhe Liu, Steve Cox, John Little, Wolfgang Horn, Olaf Wilke, Katharina Wiegner
Product emissions chamber testing involves a complex protocol with several sources of measurement uncertainty (ASTM, 2010; ISO, 2006). Despite the potential for significant variability in measurement results within and among laboratories, there is no

Rheological Characterization of Flow Table Reference Material

April 29, 2011
Author(s)
Chiara F. Ferraris, Haleh Azari
The flow table is a standardized test that is widely used to qualify a mortar to be tested for compressive strength and air content. It is also the only standard test to quantify a mortar workability property. Therefore, the calibration of this device is

LABORATORY ACCELERATED AND NATURAL WEATHERING OF STYRENE-ETHYLENE-BUTADIENE-STYRENE (SEBS) BLOCK COPOLYMER: ACCELERATION AND CORRELATION

March 23, 2011
Author(s)
Kar T. Tan, Christopher C. White, David J. Benatti, Deborah S. Jacobs, Donald L. Hunston
Indoor accelerated and outdoor field weathering of styrene-ethylene-butadiene-styrene block copolymer have been studied by Fourier transform infrared (FTIR) spectroscopy. In the indoor accelerated experiments, specimens are exposed to ultraviolet-visible

Technical Study of the Sofa Super Store Fire, South Carolina, June 18, 2007, Volume I

March 14, 2011
Author(s)
Nelson P. Bryner, Stephen P. Fuss, Bryan W. Klein, Anthony D. Putorti Jr.
A fire occurred on the evening of June 18, 2007, in the Sofa Super Store in Charleston, SC. NIST analyzed the fire ground, consulted with other experts, and performed computer simulations of fire growth alternatives. Based on these analyses, the following

High Pressure Release and Dispersion of Hydrogen in a Partially Enclosed Compartment

March 1, 2011
Author(s)
Kuldeep R. Prasad, Thomas G. Cleary, William M. Pitts, Jiann C. Yang
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 direct PRD

CHARACTERIZING FIREBRAND EXPOSURE DURING WILDLAND-URBAN INTERFACE FIRES.

February 2, 2011
Author(s)
Samuel L. Manzello, Ethan I. Foote, John Liu
This study examines the size distribution and other characteristics of firebrand exposure during the 2007 Angora Fire, a severe Wildland-Urban Interface (WUI) fire in California. Of the 401 houses that received direct interface fire exposure 61% were

EXPOSING SIDING TREATMENTS AND WALLS FITTED WITH EAVES TO FIREBRAND SHOWERS

February 2, 2011
Author(s)
Samuel L. Manzello, Sayaka S. Suzuki, Yoshihiko Hayashi
An experimental campaign was undertaken to determine vulnerabilities of siding treatments and walls fitted with eaves to firebrand bombardment using the NIST Dragon installed in the Building Research Institute’s Fire Research Wind Tunnel Facility (FRWTF)

Spent Fuel Cask Seal Performance Testing: Interim Report (NIST TN 1687)

January 31, 2011
Author(s)
Jiann C. Yang, Edward J. Hnetkovsky
High-temperature metallic seal performance tests were performed. All the tests were conducted at either 800 °C or 427 °C for 9 hours in a electrical furnace. In the three repeated tests under similar beyond-design-basis thermal exposure conditions of 9

Enticing arsonists with broken windows and social disorder

January 6, 2011
Author(s)
Douglas Thomas, David Butry, Jeffrey P. Prestemon
Arson rates vary widely across the U.S., and much of this variation can be traced to fuel and weather factors related to ignition success and socioeconomic factors shown to influence crime rates. In criminology, it is well understood that indicators of

Droplet/Surface Interaction: Relevance to Fire Suppression

January 5, 2011
Author(s)
Anthony P. Hamins
Due to the ban of Halon 1301 under the Montreal Protocol, new liquid fire suppressants have been proposed as possible alternatives to Halon 1301 in certain fires. It has been reported that in the case of water mist fire suppression systems, a large
