Abstract

A wildfire defense spraying process for spraying and protecting property and combustible surfaces with an environmentally-clean water-based liquid fire inhibitor that inhibits fire ignition and flame spread caused by hot flying wildfire embers created during a wildfire storm. The wildfire defense spraying process involves maintaining a storage tank containing a supply of environmentally-clean water-based liquid fire inhibitor comprising a major amount of tripotassium citrate (TPC) and minor amount of triethyl citrate (TEC) dissolved in a major amount of 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 ready for immediate spraying on combustible property. When a spraying-trigger signal is received by an automated wildfire detection system, a mobile phone or other intelligent source, an electric-powered hydraulic pump system is automatically energized and pumps environmentally-clean water-based liquid fire inhibitor from the storage tank through piping, under pressure, to spray heads mounted about the property, to produce a spray pattern of environmentally-clean water-based liquid fire inhibitor that covers all the property and combustible surfaces to be defended against wildfire. When the hydraulic pump system completes its pumping operations, the hydraulic pump system automatically shuts off. As water molecules in the sprayed environmentally-clean water-based liquid fire inhibitor evaporates to the environment, thin fire-inhibiting potassium salt crystalline coatings form on the sprayed combustible surfaces, inhibiting fire ignition and flame spread in the presence of wildfire embers.

First claim

What is claimed is:

1. A wildfire defense spraying process for spraying a combustible building on property with an environmentally-clean water-based liquid fire inhibitor that inhibits fire ignition and flame spread caused by hot flying wildfire embers created during a wildfire storm, said wildfire defense spraying process comprising the steps of:
(a) maintaining a supply tank containing a supply of environmentally-clean water-based liquid fire inhibitor comprising a major amount of an alkali metal salt of a nonpolymeric carboxylic acid, and a minor amount of a coalescing agent realized in the form of an organic chemical compound dissolved in a major amount of water according to a prespecified formulation, wherein said environmentally-clean water-based liquid fire inhibitor remains stable without the formation of solids at expected operating temperatures, and ready for immediate spraying on the property;
(b) using an electric-powered hydraulic pump system to pump said environmentally-clean water-based liquid fire inhibitor from said supply tank through piping to a set of spray heads mounted about the building and said property, to produce a spray pattern of environmentally-clean water-based liquid fire inhibitor covering the building and property to be defended against wildfire; and
(c) wherein, when said electric-powered hydraulic pump system completes pumping environmentally-clean water-based liquid fire inhibitor from said supply tank and its automated spraying operations, said electric-powered hydraulic pump system automatically stops pumping operations, and as water molecules in the environmentally-clean water-based liquid fire inhibitor evaporate to the environment, thin fire-inhibiting alkali metal salt crystalline coatings form on the sprayed property, inhibiting fire ignition and flame spread in the presence of wildfire.

2. The wildfire defense spraying process of claim 1 , wherein step (b) comprises sending an electronic message over a digital cellular network to automatically activate said electric-powered hydraulic pump system via a wireless remote power control switch used in said wildfire defense spraying system.

3. The wildfire defense spraying process of claim 1 , wherein step (b) comprises using a mobile smartphone to send an electronic message over a digital cellular communication link between said mobile smartphone and a wireless remote power control switch employed to supply electrical power to said electric-powered hydraulic pump system at said wildfire defense spraying system.

4. The wildfire defense spraying process of claim 1 , wherein step (b) comprises receiving a radio control signal over a digital cellular communication network, and automatically triggering the spraying of said environmentally-clean water-based liquid fire inhibitor from said storage tank when said radio control signal is transmitted by a mobile smartphone operating over said digital cellular communication network.

5. The wildfire defense spraying process of claim 1 , wherein said alkali metal salt comprises tripotassium citrate (TPC) and said coalescing agent comprises triethyl citrate (TEC), and wherein said thin fire-inhibiting alkali metal salt crystalline coatings comprise thin fire-inhibiting potassium salt crystalline coatings.

6. The wildfire defense spraying process of claim 1 , wherein said expected operating temperatures of said wildfire defense spraying process extend over a range from about 34 F to about 120 F.

7. The wildfire defense spraying process of claim 1 , wherein said spray pattern comprises a linear spray pattern generated by said spray heads mounted on the property to form a clean-chemical wildfire break against any incidence of a wildfire storm.

8. The wildfire defense spraying process of claim 1 , wherein said spray pattern comprises a resulting spray pattern encircling the property generated by said spray heads mounted on the property to form a clean-chemical wildfire protection zone against any incidence of a wildfire storm.

9. A wildfire defense spraying process supported on a parcel of property having a building thereon, said wildfire defense spraying process comprising the steps of:
(a) maintaining a storage tank containing a supply of environmentally-clean water-based liquid fire inhibitor comprising a major amount of an alkali metal salt of a nonpolymeric carboxylic acid, and a minor amount of a coalescing agent realized in the form of an organic chemical compound dissolved in a major amount of water according to a prespecified formulation, wherein said environmentally-clean water-based liquid fire inhibitor remains stable without the formation of solids at expected operating temperatures, and ready for immediate spraying on the property;
(b) using a battery power supply system to supply electrical power to an electric-powered hydraulic pump system connected to said storage tank, and pumping environmentally-clean water-based liquid fire inhibitor through piping operably connected to a set of spray heads mounted about the building and property, and spraying said environmentally-clean liquid fire inhibitor according to spray patterns generated by said spray heads, and covering the property and building to be defended against wildfire; and
(c) wherein, when said electric-powered hydraulic pump system completes pumping the environmentally-clean water-based liquid fire inhibitor from said storage tank through said piping and said spray heads to produce a spray pattern of environmentally-clean water-based liquid fire inhibitor over the property and building, said electric-powered hydraulic pump system automatically stops pumping operations, and as water molecules in the environmentally-clean water-based liquid fire inhibitor begin to evaporate, thin fire-inhibiting alkali metal salt crystalline coatings form on the sprayed property and building, inhibiting fire ignition and flame spread in the presence of wildfire.

10. The wildfire defense spraying process of claim 9 , wherein said alkali metal salt comprises tripotassium citrate (TPC) and said coalescing agent comprises triethyl citrate (TEC), and wherein said thin fire-inhibiting alkali metal salt crystalline coatings comprise thin fire-inhibiting potassium salt crystalline coatings.

11. The wildfire defense spraying process of claim 9 , wherein said expected operating temperatures of said wildfire defense spraying process extend over a range from about 34 F to about 120 F.

12. The wildfire defense spraying process of claim 9 , wherein said spray pattern comprises a linear spray pattern generated by said spray heads mounted on the property to form a clean-chemical wildfire break against any incidence of a wildfire storm.

13. The wildfire defense spraying process of claim 9 , wherein said spray pattern comprises a resulting spray pattern encircling the property generated by said spray heads mounted on the property to form a clean-chemical wildfire protection zone against any incidence of a wildfire storm.

14. A wildfire defense spraying process supported on property with a building to be protected against wildfire, said wildfire defense spraying process comprising the steps of:
