NIST TEAM DEVELOPS SCREENING TOOL FOR NEW FIRE SUPPRESSANTS.

The Next Generation Fire Suppression Technology Program, led by a MST scientist, is the Department of Defense's research effort to identify alternatives to the commonly used fire suppressant halon 1301 ([CF.sub.3]Br), now known to deplete stratospheric ozone. A key portion of this program is the development of tools to evaluate the fire suppression performance of new candidate extinguishants for use in suppressing in-flight aircraft fires. A NIST team has completed work on the Transient Application, Recirculating Pool Fire (TARPF) Facility. This device measures the suppression effectiveness of impulsively discharged gases (such as from a pressurized storage bottle or solid propellant gas generator), the impact of a hot surface on continuous suppression, the impact of a recirculating flow and the impact of a liquid spray. The flow patterns in the device have been modeled to extend the applicability of the experimental results to a variety of conditions prevalent during aircraft fires.
