DNA-based Nanocomposite Bio-Coatings for Fire Retarding Polyurethane Foam

May 2, 2014
Author(s)
Yu-Chin Li, Yeon S. Kim, John R. Shields, Rick D. Davis
Layer-by-Layer (LbL) assembled multilayer thin films of deoxyribonucleic acid (DNA), chitosan (CHI), and montmorillonite (MMT), were studied in an effort to produce fully renewable, bio-based fire retardant coatings for flexible polyurethane foam. The PUF

Evaluating Fire Blocking Performance of Barrier Fabrics

October 15, 2013
Author(s)
Shonali Nazare, William M. Pitts, Shaun M. Flynn, John R. Shields, Rick D. Davis
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

OBSERVATIONS ON THE GENERATION OF TOXIC PRODUCTS IN THE ISO/TS 19700 CONTROLLED EQUIVALENCE RATIO TUBE FURNACE AND THE CONTROLLED ATMOSPHERE CONE CALORIMETER

June 24, 2013
Author(s)
Nathan D. Marsh, Richard G. Gann, John R. Shields, Marc R. Nyden
Efforts are underway in several research groups to adapt existing flammability test methods for the determination of yields of toxic compounds such as CO, HCN, and HCl. These include the NFPA 269 / ASTM E 1678 radiant furnace apparatus, the ISO/TS 19700

Guidelines for Evaluating Fire Blocking Barrier Fabrics

April 18, 2013
Author(s)
Shonali Nazare, William M. Pitts, Shaun M. Flynn, Rick D. Davis, John R. Shields
This document provides guidelines to quantify fire performance properties of fire blocking barrier materials used in soft furnishings. In an attempt to enable a priori selection of fire barrier materials such that the final upholstered product complies

Comparison Testing Protocol for Firebrand Penetration through Building Vents: Summary of BRI/NIST Full Scale and NIST Reduced Scale Results

January 25, 2010
Author(s)
Samuel L. Manzello, Seul-Hyun Park, John R. Shields, Yoshihiko Hayashi, Sayaka Suzuki
An ASTM task group on vents, organized within Subcommittee E05.14.06, External Fire Exposures, has developed a reduced scale test method (not presently a standard) aimed at evaluating the ability of vents to resist firebrand intrusion into attic and crawl

On the Development and Characterization of a Firebrand Generator

Author(s)
Samuel L. Manzello, John R. Shields, Thomas G. Cleary, Alexander Maranghides, William E. Mell, Jiann C. Yang, Yoshihiko Hayashi, Daisaku Nii, Tsuyoshi Kurita
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

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

Assessment of a Medium-Scale Polyurethane Foam Flammability Test.

February 1, 2008
Author(s)
Thomas J. Ohlemiller, John R. Shields
Six polyurethane foams of widely varying flame retardant levels have been tested in two modes: as four, fabric-wrapped cushions in a chair mock-up based on California Technical Bulletin 133 and in a two foam slab Vee configuration that uses multiple

Aspects of the Fire Behavior of Thermoplastic Materials.

January 1, 2008
Author(s)
Thomas J. Ohlemiller, John R. Shields
Thermoplastic polymers pose unique new challenges (resulting from the movement of burning melt material) for the understanding and control of fire growth on objects that incorporate them. Both full density thermoplastics such as polypropylene and

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

High Throughput Flammability Characterization Using Gradient Heat Flux Fields.

December 1, 2005
Author(s)
Jeffrey W. Gilman, Rick D. Davis, John R. Shields, Richard H. Harris Jr.
The quest for small-scale flammability tests useful for predicting large-scale fire test performance is an enduring undertaking. Often, this work is motivated by limited access to larger quantities of samples, in the case of materials development efforts

Nanoparticle Networks Reduce the Flammability of Polymer Nanocomposites.

December 1, 2005
Author(s)
Takashi Kashiwagi, F Du, J F. Douglas, K I. Winey, Richard H. Harris Jr., John R. Shields
Synthetic polymeric materials are rapidly replacing more traditional inorganic materials, such as metals, and natural polymeric materials, such as wood. As these synthetic materials are flammable, they require modifications to decrease their flammability

Nanoparticle Networks Reduces Flammability of Polymer Nanocomposites

December 1, 2005
Author(s)
Takashi Kashiwagi, F Du, K Winey, Jack F. Douglas, Richard H. Harris Jr., John R. Shields
Synthetic polymer materials are rapidly replacing more traditional materials such as steel, nonferrous metals and natural polymeric materials. Because these novel materials are combustible under certain conditions, their utilization often requires

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
