SWIRL METHODS FOR BLANKETING A TANK WITH FOAM TO COMBAT FIRE OR HAZARD, PARTICULARLY FOR ALCOHOLS OR THE LIKE

摘要

Methods for blanketing a tank containing a flammable/combustible liquid, and in particular hydrophilic liquids, polar solvents, alcohols or ethanols or the like, with foam, including landing primary nozzle footprints) proximate to, or on, downwind inner tank wall portions, the trajectories streaming generally with the wind over upwind tank wall portions and rebounding off of downwind inner tank wall portions at an acute angle, less than perpendicular, thereby inducing a general swirl foam run pattern.
