Operation Tomodachi -Fire Research Special Issue

July 1, 2016
Author(s)
Samuel L. Manzello, Sayaka Suzuki
NIST’s Engineering Laboratory (EL-NIST) hosted “Operation Tomodachi – Fire Research” on March 16-18, 2015 in Gaithersburg, MD USA. Tomodachi means friendship in Japanese. This workshop was organized by Dr. Samuel L. Manzello of EL-NIST in partnership with

Firebrand Production from Building Components Fitted with Siding Treatments

February 1, 2016
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Firebrand production from real-scale building components under well-controlled laboratory conditions was investigated. Re-entrant corner assemblies were ignited and during the combustion process, firebrands were collected to determine the size/mass

Reduced-scale Experimental Facility to Characterize Firebrand Ignition

November 16, 2015
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Large outdoor fires are a problem in Japan and the USA. In order to prevent losing structures to large outdoor fires, it is important to understand the vulnerabilities of structures to firebrand showers and then, strengthen structures to these exposures

A dimensional analysis on firebrand penetration through a mesh screen

November 15, 2015
Author(s)
Jiann C. Yang, Samuel L. Manzello
A dimensional analysis on firebrand penetration through a mesh screen was carried out to provide a framework to correlate a limited set of experimental data previously reported by Manzello et al. (2011). Two dimensionless variables were obtained. The

Ignition of Wood Fencing Assemblies Exposed to Continuous-Wind Driven Firebrand Showers

July 30, 2015
Author(s)
Sayaka Suzuki, Erik L. Johnsson, Alexander Maranghides, Samuel Manzello
A series of experiments were conducted to examine ignition of wood fencing assemblies subjected to continuous, wind-driven firebrand showers. Specifically, Western Red Cedar and Redwood fencing assemblies were exposed to continuous, wind-driven firebrand

BUILDING COMPONENT IGNTION FROM MULCH BEDS IGNITED BY FIREBRAND SHOWERS

May 16, 2015
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Daisaku Nii
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the world. The 2007 Southern California Fire forced 300,000 people to evacuate, destroyed over one thousand structures, and

DEVELOPMENT OF REDUCED-SCALE EXPERIMENTAL FACILITY TO STUDY FIREBRAND IGNTION

May 16, 2015
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the USA. The best way forward to address the WUI fire problem is hardening of structures [1]. Without standard laboratory

EFFECT OF SIDING TREATMENT ON FIREBRAND PRODUCTION FROM BUILDING COMPONENTS

February 2, 2015
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Wildfires which spread into a community, commonly known as Wildland-Urban Interface (WUI) fires, is a significant problem all over the world. Post-fire investigations have suggested that firebrands are the major cause of structure ignitions. Yet, few

Firebrand Accumulation in Front of Structures in Large Outdoor Fires

December 10, 2014
Author(s)
Samuel L. Manzello, Sayaka Suzuki
The production of firebrands contributes to the spread of disastrous large outdoor fires. As structures are exposed to wind, stagnation planes are produced around structures. In a prior scoping study, the authors demonstrated that firebrands may accumulate

Ignition of Mulch beds exposed to firebrand showers

December 10, 2014
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Mulch is commonly found near buildings and is a useful surrogate to study various fuels that may be present near buildings. To this end, mulch beds were exposed to continuous, wind-driven firebrand showers. These experiments build on our prior work where

Hardening Structures to Resist Wildland-Urban (WUI) Fire Exposures

November 14, 2014
Author(s)
Samuel L. Manzello
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the world. In the USA, over 46 million homes in 70,000 communities are at risk of WUI fires [1-2]. Historically, fire safety

Hardening of Structures to Wildland-Urban Interface (WUI) Fire Expsoures

Samuel L. Manzello
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the world. In the USA, over 46 million homes in 70,000 communities are at risk of WUI fires [1-2]. These fires have destroyed

Ignition of Mulch Beds Exposed to Continuous-Wind Driven Firebrand Showers

August 3, 2014
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Koji Kagiya, Junichi Suzuki, Yoshihiko Hayashi
A series of experiments were conducted to examine ignition of mulch beds to continuous, wind-driven firebrand showers. Shredded hardwood mulch, fitted in beds 1.2 m by 1.2 m with a thickness of 51 mm, was attached to a non-combustible re-entrant corner

Experimental Study of Firebrand Transport

June 1, 2014
Author(s)
Samuel L. Manzello, Kuibin Zhou, Sayaka Suzuki
The NIST Firebrand Generator (NIST Dragon) has been used to quantify the vulnerability of structures to ignition by firebrand attack. The Firebrand Generator is also as useful device to study firebrand transport, and has been used to validate firebrand

Exposing Decking Assemblies to Continuous Wind-Driven Firebrand Showers

June 1, 2014
Author(s)
Samuel L. Manzello, Sayaka Suzuki
A series of experiments were conducted to examine potential vulnerabilities of wood decks to continuous, wind-driven firebrand showers. Sections of wood decks (1.2 m by 1.2 m) were constructed and attached to a re-entrant corner assembly. The deck
