The compos ii ion of tlie solution used for the fot mat ion of the bubbles has not been ruvealefl by tho inventors. The froth resulting from the release of the liquid from the extinguisher is eight times in volume, that of the original liquid, which therefore, gives it. a largo area-covering capacity. Tli -3 physical properties show the froth to he heavy, tenacious and lusting. Portable means for the application appli-cation of tho method have been provided bv the tine of fire pails, hand ex tin -j'.maters ami portable engines. For large itorage tanks permanent installations are u;ed. Recently a fo.fiftO-barrel tank, when burning at its height, was saved from total destruction bv this method of fire righting. Foitv-eight seconds after application ap-plication the foam blanket smothered the blaze. Tho tank was 114 feet in diameter, diam-eter, presenting 10.200 square feet of surface. sur-face. Projecting of the liquid was accomplished ac-complished by the use of two contain-! contain-! era placed on opposite sides of the tank. According to the experiments conducted, the am-.uiit of foam required can be calculated' cal-culated' m iteconiiuice with the nature of me fire risk and die number of square feet of area requiring protection.
