The how, what, and where of safety zones: recent findings

Date: December 2, 2014
Presenter(s): Bret W. Butler
Description: Bret Butler presented a webinar on December 2, 2014. Current safety zone guidelines for wildland firefighters are based on the assumption of flat ground, no wind, and radiative heating only. Recent measurements in grass, shrub and crown fires indicate that convective heating can be significant especially when wind or slope are present. Measurements and computer modeling supports this finding and suggests that convective energy transport should be considered when assessing safety zone effectiveness any time wind or slope is present. The results of the research are presented along with recommendations for modifications to current safety zone guides.
