Less chance of “fire at your back”

 

During aggressive interior attacks of pre-flashover fires, applying compressed-air foam absorbs more heat than water, lessening the chance of potentially deadly fire compartment flashover. As attack teams advance through dwelling interiors and move past rooms where flames have been knocked-down, the wetting and penetrating action of a foam blanket applied on room furnishings reduces the chance of a rekindle and “fire at their backs.”
