Results from a Full-scale Smoke Alarm Sensitivity Study

February 27, 2009
Author(s)
Thomas G. Cleary
A series of 24 full-scale experiments was conducted during the summer of 2008 to examine the effects of alarm type (photoelectric, ionization, and dual sensor), alarm location, fabric type (100 % cotton and 100 % polyester), polyurethane foam density

On the Development and Characterization of a Firebrand Generator

May 1, 2008
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

TOWARDS A TEST METHOD FOR HYDROGEN SENSOR PERFORMANCE

April 2, 2008
Author(s)
Nathan D. Marsh, Thomas G. Cleary
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)

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

Performance of Home Smoke Alarms Analysis of the Response of Several Available Technologies in Residential Fire Settings (NIST TN 1455-1)

December 1, 2007
Author(s)
Richard W. Bukowski, Richard D. Peacock, Jason D. Averill, Thomas G. Cleary, Nelson P. Bryner, William D. Walton, Paul A. Reneke, Erica D. Kuligowski
This report presents the results of the project and provides details of the response of a range of residential smoke alarm technologies in a controlled laboratory test and in a series of real-scale tests conducted in two different residential structures

Preliminary Performance Assessment of Commercially-Available Hydrogen Sensors

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

Firebrand Production From Burning Vegetation

November 30, 2006
Author(s)
Samuel L. Manzello, Alexander Maranghides, William E. Mell, Thomas G. Cleary, 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

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

A Test Methodology for Multiple Sensor Multiple Criteria Alarms

September 26, 2004
Author(s)
Thomas G. Cleary
Multiple sensor-multiple criteria fire alarms hold promise for improving fire detection by both increasing sensitivity to fire while decreasing nuisance alarms. Eventually, to provide a fair assessment of performance, some type of uniform testing protocol

Residential Nuisance Source Characteristics for Smoke Alarm Testing

September 16, 2004
Author(s)
Thomas G. Cleary
Nuisance scenario tests were performed in the manufactured home used in the Home Smoke Alarm fire test series. The scenario selections were based on what are commonly thought to be causes of residential nuisance alarms, and were designed to mimic normal
