Experimental Investigation of Firebrands: Generation and Ignition of Fuel Beds

April 1, 2008
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Alexander Maranghides, William E. Mell, Jiann C. Yang
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

Analysis of Inter-laboratory Testing of Non-loadbearing Gypsum/Steel-Stud Wall Assemblies

December 1, 2007
Author(s)
William L. Grosshandler, Samuel L. Manzello, Alexander Maranghides, T Mizukami
This report summarizes the results of a test program conducted in 2006 and 2007 by the North American Fire Testing Laboratories (NAFTL) consortium. Gypsum/steel-stud wall assemblies, nominally rated at 1-h, were tested by six different organizations in

Firebrand Generation From Burning Vegetation

February 20, 2007
Author(s)
Samuel L. Manzello, Alexander Maranghides, William E. Mell
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 experiments were performed in the Large Scale Fire Laboratory (LFL) at NIST. The

On the Ignition of Fuel Beds by Firebrands.

December 1, 2006
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Jiann C. Yang
An experimental apparatus has been built to investigate the ignition of fuel beds as a result of impact with burning firebrands. The apparatus allowed for the ignition and deposition of both single and multiple firebrands onto the target fuel bed. The

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

Ignition of Vegetation and Mulch by Firebrands in Wildland/Urban Interface (WUI) Fires.

November 13, 2005
Author(s)
Samuel L. Manzello, Thomas G. Cleary, John R. Shields, Jiann C. Yang
Firebrands or embers are produced as trees and structures burn in wildland/urban interface (WUI) fires. Hot firebrands ultimately come to rest and may ignite fuels far removed from the fire, resulting in fire spread. It is believed that firebrand showers

Measurement of Thermal Properties of Gypsum Board at Elevated Temperatures

May 30, 2005
Author(s)
Samuel L. Manzello, Seul-Hyun Park, Dale P. Bentz, Tensei Mizukami
The thermal conductivity, specific heat, mass loss, and linear contraction for gypsum board types widely used in the USA and Japan were measured both at room temperature and elevated temperatures. The gypsum board types tested include Type X and Type C
