Abstract

A remotely-triggered wildfire defense spraying system installed on property with a building, and adapted for spraying the building and property with an environmentally-clean water-based liquid fire inhibitor for defending against wildfire by inhibiting fire ignition and flame spread caused by hot flying wildfire embers created during a wildfire storm. The wildfire defense spraying system includes: a storage tank containing environmentally-clean liquid fire inhibitor comprising an alkali metal salt of a nonpolymeric carboxylic acid, and triethyl citrate (TEC) dissolved in water according to a prespecified formulation, wherein the environmentally-clean water-based liquid fire inhibitor remains stable without the formation of solids at expected operating temperatures, and for immediate spraying on property. A fluid pumping loop having a hydraulic pump system is connected to spray heads and the storage tank, and is operably controlled by a remote control switch. When the hydraulic pump system is remotely activated by a remotely generated trigger signal (e.g. from a mobile smartphone or remote wildfire detection system), the hydraulic pump system pumps environmentally-clean water-based liquid fire inhibitor from the storage tank and through the spray heads to produce a spray pattern of environmentally-clean water-based liquid fire inhibitor covering the combustible surfaces on the property. As water molecules in the sprayed environmentally-clean water-based liquid fire inhibitor evaporate to the environment, fire-inhibiting alkali metal salt crystalline coatings form on the sprayed combustible surfaces, inhibiting fire ignition and flame spread in the presence of wildfire embers.
