Real-Time Particulate Monitoring - Detecting Respiratory Threats for First Responders: Workshop Proceedings

December 1, 2007

Author(s)

Rodney A. Bryant, Kathryn M. Butler, R Vettori, P Greenberg

The overhaul of a fire scene is a stage of firefighting where respiratory protection is often disregarded due to the perception of low risk and the desire to remove the heavy and cumbersome self-contained breathing apparatus. The need for alternative

Real-Time Particulate Monitoring Detecting Respiratory Threats for First Responders: Workshop Proceedings

December 1, 2007

Author(s)

Rodney A. Bryant, Kathryn M. Butler, R Vettori, P Greenberg

This workshop brought together members of the fire service, particulate detector manufacturers, public health professionals, airborne particulate researchers, and standards organizations to discuss the need for better technology to assess the level of

A New Approach to Ventilation Measurements in Enclosure Fires

September 5, 2007

Author(s)

Rodney A. Bryant

The application of Stereoscopic Particle Image Velocimetry (SPIV) is a new approach to quantifying the ventilation in enclosure fires. SPIV is a non-intrusive optical measurement technique which measures the displacement of tracer particles in a flow. The

Author(s)

Rodney A. Bryant

There is a need for real-time identification of hazards to enable selection of appropriate respiratory protection for firefighters. The challenge is to transfer the protocols and technology used in industrial environments where the respiratory threats are

Characterization and Identification of Super-Effective Thermal Fire Extinguishing Agents. Final Report. NGP Project 4C/1/890.

December 1, 2006

Author(s)

William M. Pitts, Rodney A. Bryant, L G. Blevins, M L. Huber

The use of halon 1301 for fire fighting is being phased out due to its deleterious effects on stratospheric ozone. This report summarizes the findings of a three-year study designed to characterize and identify super-effective thermal fire-fighting agents

Large-Scale Particle Image Velocimetry Measurements of a Fire-Induced Doorway Flow.

November 13, 2005

Author(s)

Rodney A. Bryant, Erik L. Johnsson

Quantifying the ventilation available to a room fire is an important step to understanding fire behavior. The fresh air that moves into an enclosure provides the oxygen necessary to support the combustion while also serving to moderate the temperature of

Dissipation of Oxygen From Outward Leak of Closed Circuit Breathing Device

October 18, 2005

Author(s)

Kathryn M. Butler, Rodney A. Bryant, J G. Kovac

Closed circuit breathing devices recycle exhaled air after scrubbing carbon dioxide and adding make-up oxygen from a tank of pure oxygen. Use of this equipment allows first responders to work for up to four hours without swapping out cylinders

Particle Image Velocimetry Measurements of Buoyancy Induced Flow Through a Doorway

September 1, 2005

Author(s)

Rodney A. Bryant

Quantifying the ventilation available to an enclosure fire is an important step to understanding fire behavior. Accurate measurements of mass flow rate across an enclosure opening require a complete mapping of the velocity and density fields due to the

Stereoscopic Particle Image Velocimetry Measurements of Flow Through a Doorway of an Enclosure Fire Analogue

March 23, 2005

Author(s)

Rodney A. Bryant

A fire within a room or enclosure acts as a pump, pulling ambient air in while pushing combustion products mixed with air out. The openings through which the gases flow are referred to as vents and typically are doorways and windows. Quantifying the
