After the Alarm Sounds: How We Got Here, Where We Are, and Where We Should Go

April 1, 2011
Author(s)
Jason D. Averill, Erica D. Kuligowski, Richard D. Peacock
This article reviews the history of egress design and code requirements in the United States, describes the current state-of-the-art in egress design and modeling, and offers a strawman research agenda for future egress research.

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

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

Building Occupant Egress Data

August 27, 2010
Author(s)
Richard D. Peacock, Erica D. Kuligowski
Data on people movement on stairs were collected from 9 office and residential building evacuations in the United States. The buildings involved in this study range from 6 stories to 62 stories in height. The data were collected by positioning video

Report on Residential Fireground Field Experiments

April 27, 2010
Author(s)
Jason D. Averill, Lori Moore-Merrell, Adam M. Barowy, Robert Santos, Richard D. Peacock, Kathy Notarianni, Doug Wissoker
Over the past three decades, fire department response has expanded from fire prevention and fire suppression to include multiple other community services such as emergency medical services, hazardous materials response, and special rescue. Today, service

Rethinking Egress: A Vision for the Future

November 30, 2009
Author(s)
Jason D. Averill, Richard D. Peacock
New technologies and research are redefining the state-of-the-art in building evacuation. The time is right to rethink the entire infrastructure of egress from buildings in light new opportunities to address the economic and life-safety issues

Building Occupant Safety Research 2008

June 12, 2009
Author(s)
Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski, Richard W. Bukowski
Historically, building egress systems have evolved in response to specific large loss incidents. Currently, systems are designed around a concept of providing stair capacity for the largest occupant load floor in the building with little or no

Stairwell Evacuation from Buildings: What We Know We Don't Know

June 12, 2009
Author(s)
Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski
Occupant descent down stairwells during building evacuations is typically described by measureable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn, predictive models of building evacuation use these

Mass Notification Messages: Workshop Proceedings

March 30, 2009
Author(s)
Erica D. Kuligowski, Richard D. Peacock, Jason D. Averill, Richard W. Bukowski
This workshop provided a forum to discuss research and best practices regarding mass notification message creation and dissemination. The goal of the workshop was to provide a forum where representatives from federal agencies could exchange ideas and

Stairwell Evacuation from Buildings: What We Know We Don't Know

January 1, 2009
Author(s)
Richard D. Peacock, Jason D. Averill, Erica D. Kuligowski
Occupant descent down stairwells during building evacuations is typically described by measurable engineering variables such as stairwell geometry, speed, density, and pre-evacuation delay. In turn, predictive models of building evacuation use these

On the Significance of Transient Heat Release Rate Excursions Above a Set Limit

November 1, 2008
Author(s)
Thomas J. Ohlemiller, Richard D. Peacock
When a heat release rate limit for a consumer product is set by a regulatory agency, it is of interest to know whether small excursions above that limit, such as may occur due to production line variability, represent a disproportionate increase in fire

Smoke Control and Occupant Evacuation at the World Trade Center

June 21, 2008
Author(s)
M J. Ferreira, S M. Strege, Richard Peacock, Jason D. Averill
This paper examines smoke control and occupant evacuation in WTC 1 and WTC 2 on September 11, 2001focusing on the impact region and above for each tower. Approximately 2,000 individuals were at or above the area of impact in WTC 1 and WTC 2 who did not

Required Safe Egress Time: Data and Modeling

January 1, 2008
Author(s)
Jason D. Averill, Paul A. Reneke, Richard D. Peacock
This paper identifies sources of uncertainty in RSET (required safe egress time) calculations, with focus on data and modeling. A model for efficiently calculating the range of egress solutions for a particular design is presented. Three recommendations

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
