Suppression Limits of Low Strain Rate Non-Premixed Flames

January 5, 2011
Author(s)
Matthew F. Bundy, Anthony P. Hamins
The suppression of low strain rate non-premixed flames was investigated experimentally in a counterflow configuration through the development of a methodology that allows establishment of laminar flames free from conductive heat losses. The method allows

Clean agent suppression of energized electrical equipment fires

January 3, 2011
Author(s)
Gregory T. Linteris
The NFPA 2001 standard on the use of clean agents for the suppression of fires arose from the phase-out of Halon 1301. Standard methods exists for specifying the amount of clean agent required for Class A and Class B fires, but the recommendation for Class

Effects of Fuel Location and Distribution on Full-Scale Underventilated Compartment Fires

January 3, 2011
Author(s)
Andrew J. Lock, Cheolhong Hwang, Matthew F. Bundy, Erik L. Johnsson, Gwon H. Ko
Experimental and numerical studies were conducted to investigate the effect of fuel location and distribution on full-scale underventilated compartment fires in an ISO 9705 room. Heptane fuel was burned in three different fuel distributions: single

Modeling Smoldering Fires using the Computer Model CONTAM

December 1, 2010
Author(s)
William D. Davis
The computer model CONTAM was used to simulate the spread of smoke in a house with a working furnace during smoldering fires. Three smoldering experiments from a study on detector sensitivity and siting requirements conducted in 1975 using a two story

Fire Suppression

November 16, 2010
Author(s)
Cary Presser, Jiann C. Yang
Water sprinkler sprays (with relatively large droplet sizes) in residential and commercials structures are probably the most well known application of sprays in fire suppression. In more recent years, water mists (characterized by reduced droplet sizes

PERFORMANCE ASSESSMENTS INSIGHTS ON THE USE OF CEMENTS IN WASTE MANAGEMENT

November 7, 2010
Author(s)
David W. Esh, Jacob Philip, Kenneth A. Snyder
The use of cementitious materials has been proposed in a variety of waste management systems because these materials can have a variety of desirable performance characteristics: hydraulic isolation, chemical isolation, structural stability. Cementitious

A Review of Building Evacuation Models, 2nd Edition

November 1, 2010
Author(s)
Erica D. Kuligowski, Richard D. Peacock, Bryan L. Hoskins
Evacuation calculations are increasingly becoming a part of performance-based analyses to assess the level of life safety provided in buildings. In some cases, engineers are using back-of-the-envelope (hand) calculations to assess life safety, and in

Technical Study of the Sofa Super Store Fire- South Carolina, June 18, 2007 Volume I ***DRAFT FOR PUBLIC COMMENT*** (for final version, see NIST SP 1118, March 2011)

October 28, 2010
Author(s)
Nelson P. Bryner, Anthony D. Putorti Jr., Stephen P. Fuss, Bryan W. Klein
A fire occurred on the evening of June 18, 2007, in the Sofa Super Store in Charleston, SC. NIST analyzed the fire ground, consulted with other experts, and performed computer simulations of fire growth alternatives. Based on these analyses, the following

Fire Effluent Component Yields from Room-scale Fire Tests

October 1, 2010
Author(s)
Richard G. Gann, Jason D. Averill, Erik L. Johnsson, Marc R. Nyden, Richard D. Peacock
Estimation of the time available for escape (ASET) in the event of a fire is a principal component in fire hazard or risk assessment. Valid data on the yields of toxic smoke components from bench-scale apparatus is essential to accurate ASET calculations

Methodology for Calculating Construction Industry Supply Chain Statistics

September 30, 2010
Author(s)
Douglas S. Thomas
Data from the Economic Census provides detailed statistics on the construction industry; however, the data is only gathered every five years. The Bureau of Labor Statistics provides statistics on the construction industry on an annual basis, but these

FIRE PATTERN REPEATABILITY: A LABORATORY STUDY ON GYPSUM WALLBOARD

September 1, 2010
Author(s)
Daniel M. Madrzykowski, Charles Fleischmann
In 2009, the National Research Council (U.S) published a report identifying the research needs of the forensic science community. In the field of fire investigation, one of the specific needs identified was research on the natural variability of burn

Indoor Air Quality in Sustainable, Energy Efficient Buildings

August 15, 2010
Author(s)
Andrew K. Persily, Steven J. Emmerich
Building designers, contractors, owners and managers have long been challenged with providing quality indoor environments at a reasonable energy cost. Current efforts to improve building energy efficiency, including goals of netzero energy use, are

Understanding the Hazards of Grouped Electrical Cables

August 8, 2010
Author(s)
Kevin B. McGrattan, Andrew J. Lock, Nathan D. Marsh, Marc R. Nyden, Jason Dreisbach, David Stroup
CHRISTIFIRE (Cable Heat Release, Ignition, and Spread in Tray Installations during FIRE) is a U.S. Nuclear Regulatory Commission Office of Research program to quantify the mass and energy released from burning electrical cables. This type of quantitative

Infiltration of Outdoor Ultrafine Particles into a Test House

August 2, 2010
Author(s)
Dong H. Rim, Lance L. Wallace, Andrew K. Persily
Ultrafine particles (UFP) have been related to adverse human health effects such as respiratory and cardiovascular mortality. However, human exposure to particles of outdoor origin is heavily dependent on their infiltration into homes, where most people
