Rodney A. Bryant, Olatunde B. Sanni, Elizabeth F. Moore, Robert P. Borthwick, Marco G. Fernandez, Iosif I. Shinder, Jiann C. Yang, Aaron N. Johnson
Two series of independent flow measurements were conducted for cross validation of flow velocity in the exhaust duct of the NIST Large Fire Laboratory. In the first series, two pressure measurement probe types, an S probe and a 3-D probe, were used to

A New Approach to Ventilation Measurements in Enclosure Fires

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

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

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
