Towards a Process to Quantify the Hazard of Fire Protection Design Alternatives

May 1, 2019
Author(s)
Paul A. Reneke, Morgan Bruns, Stanley W. Gilbert, Chandler P. MacLaren, Richard D. Peacock, Thomas G. Cleary, David T. Butry
There are a variety of fire protection technologies that have the potential to improve life safety in residences including barrier fabrics for upholstered furniture, new nano-scaled flame retardants, or better fire detector technology. However, there is no

Estimating Smoke Detector Effectiveness and Utilization in Homes

November 6, 2018
Author(s)
Stanley W. Gilbert
This report sets out to answer three questions. What effect does installing smoke detectors have on reported fires and casualties for the “average” household? How much of an effect would increasing smoke detector utilization have on the total number of

Evaluation of Spacecraft Smoke Detector Performance in the Low-Gravity Environment

April 25, 2018
Author(s)
Jiann C. Yang, Thomas G. Cleary, Marit Meyer, D L. Urban, George W. Mulholland, Victoria Bryg, Zeng-guang Yuan, Gary A. Ruff
In the interest of fire prevention, most materials used in the interior construction of manned spacecraft are non- flammable, however, they do produce smoke when overheated. Spacecraft smoke detectors will ideally detect smoke generated by oxidative

Polarized Light Scattering of Smoke Sources and Cooking Aerosols

October 1, 2017
Author(s)
Thomas Cleary, Amy Mensch
Light scattering data was gathered during experiments conducted in an ANSI/UL 217 test room constructed at NIST to assess the performance of currently available smoke alarms. Smoldering and flaming fires along with cooking experiments were conducted. The

Smoke Characterization and Feasibility of the Moment Method for Spacecraft Fire Detection

February 17, 2015
Author(s)
Jiann C. Yang, Thomas G. Cleary, George W. Mulholland, Marit Meyer, Victoria Bryg, D L. Urban, Zeng-guang Yuan, Gary A. Ruff
The Smoke Aerosol Measurement Experiment (SAME) has been conducted twice by NASA and provided the first real-time aerosol data in a spacecraft micro-gravity environment. Flight experiment results have recently been analyzed with respect to comparable

Pyrolysis Smoke Generated Under Low-Gravity Conditions

January 17, 2015
Author(s)
Jiann C. Yang, Thomas G. Cleary, George W. Mulholland, D L. Urban, Gary A. Ruff, Zeng-guang Yuan, Marit Meyer, Victoria Bryg
A series of smoke experiments were carried out in the Microgravity Science Glovebox on the International Space Station (ISS) Facility to assess the impact of low-gravity conditions on the size distribution and structure of the smoke aerosol. This

Smoke Alarm Performance in Kitchen Fires and Nuisance Alarm Scenarios

February 6, 2013
Author(s)
Thomas G. Cleary, Artur A. Chernovsky
Tests were conducted to assess the performance of various residential smoke alarms to kitchen fires and nuisance alarm cooking scenarios. A test structure representing a kitchen, living room and hallway was constructed to conduct the tests. Eight different

A Literature Review of the Effects of Fire Smoke on Electrical Equipment

July 31, 2012
Author(s)
Richard D. Peacock, Thomas G. Cleary, Paul A. Reneke, Daniel Murphy
A review is presented of the state of the art of smoke production measurement, prediction of smoke impact as part of computer-based fire modeling, and measurement and prediction of the impact of smoke through deposition of soot on and corrosion of

MEASUREMENTS OF EFFECTIVE DIFFUSION COEFFICIENT OF HELIUM AND HYDROGEN THROUGH GYPSUM

September 14, 2011
Author(s)
Jiann Yang, William M. Pitts, Marco Fernandez, Kuldeep Prasad
An experimental apparatus, which was based on the ¿-scale garage previously used for studying helium release and dispersion in our laboratory, was used to obtain effective diffusion coefficients of helium and hydrogen (released as forming gas for safety

An Analysis of the Performance of Smoke Alarms

June 21, 2011
Author(s)
Thomas G. Cleary
Test results from the NIST 2008 Smoke Alarm Sensitivity Study were used in a smoke alarm performance analysis to examine the effects of pre-movement time, reduced travel speeds through smoke, and smoke optical density limit on occupant survivability given

Performance of New and Aged Residential Fire Smoke Detectors

April 1, 2011
Author(s)
Jason D. Averill, Richard G. Gann, William F. Guthrie, Daniel Murphy
As part of the Consumer Product Safety Commission (CPSC) technical staff program to determine the effects of emissions from imported drywall on residential electrical, gas distribution, and fire safety components, the National Institute of Standards and

Results from a Full-Scale Smoke Alarm Sensitivity Study

April 9, 2010
Author(s)
Thomas G. Cleary
A series of 24 full-scale experiments was conducted to examine the effects of alarm type (photoelectric, ionization, and dual sensor), alarm location, fabric type (100% cotton and 100% polyester), polyurethane foam density, ignition scenario, and room

Smoke Aerosol Measuremen Experiment (SAME)

March 5, 2010
Author(s)
Jiann Yang, Thomas Cleary, D L. Urban, Gary A. Ruff, William Sheredy, Zeng-guang Yuan, G W. Mulholland
This is the final report of a research project entitled Smoke Aerosol Measurements Experiment (SAME). Smoke and/or fire detection in the spacecraft is crucial to the success of future long term space travel. It has been realized that the gravity force

Full-Scale Residential Smoke Alarm Performance

September 8, 2009
Author(s)
Thomas G. Cleary
A series of 24 full-scale experiments were conducted in a multi-room structure to examine the effects of alarm type (photoelectric, ionization, and dual sensor), alarm location, fabric type (100 % cotton and 100 % polyester), polyurethane foam density

Testing the Performance of Hydrogen Sensors

September 8, 2009
Author(s)
Nathan D. Marsh, Thomas G. Cleary
The acceptance of hydrogen as a widely-available energy source will depend to some extent on the perceived and actual safe dispensing and storage of hydrogen by the general public. Reliable detection of an accidental hydrogen gas release and mitigation of
