Alkali Metal Salt Coatings for Wildfire Property Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wildfire fighting methods are inadequate in urban areas, as they are often reactive, inefficient, and pose health risks to firefighters and the public due to the use of phosphorous-based chemicals that decompose into harmful gases, and there is a need for proactive, safer, and more effective fire inhibiting compositions to protect property and life in the Wildfire Urban Interface (WUI) regions.
Innovation Solution
Development of environmentally-clean, aqueous-based wildfire inhibiting biochemical compositions comprising alkali metal salts of non-polymerized saturated carboxylic acids, which form thin crystalline coatings on combustible surfaces to inhibit fire ignition and reduce smoke production, applied using GPS-guided spraying systems to create proactive fire barriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phosphorous-based chemicals are used for wildfire suppression, then fire fighting effectiveness is improved, but harmful gas decomposition occurs posing health risks to firefighters and the public
Solution Approach 1:
The patent converts the harmful phosphorous-based chemicals into beneficial alternatives by using potassium citrate and other safe biochemical compounds that provide fire suppression effectiveness without decomposing into harmful gases. The harmful aspect is eliminated while maintaining the protective function through naturally-derived chemicals that break down into harmless substances.
Solution Approach 2:
The patent changes the chemical composition parameters from phosphorous-based compounds to potassium citrate and other safe biochemicals. This parameter change maintains fire suppression effectiveness while altering the decomposition products from harmful gases to harmless substances, thereby resolving the contradiction between effectiveness and safety.
2Reliability
If conventional firebreak methods are used in urban areas, then fire spread is addressed, but the methods are reactive and inefficient for proactive protection
Solution Approach 1:
The patent applies preliminary action by treating combustible materials with fire-retardant compositions before wildfires occur. The compositions are applied to trees, shrubs, and other fuels in advance to create protected zones, enabling proactive fire spread prevention rather than reactive response after ignition occurs.
Solution Approach 2:
The patent uses fire-retardant chemical compositions as intermediaries between the wildfire threat and combustible materials. These compositions mediate the interaction by creating a protective layer that inhibits fire ignition and spread, enabling proactive protection without direct human intervention during the fire event.
3Reliability
If phosphorous-based fire retardants are applied, then fire suppression is achieved, but environmental pollution and health hazards are increased
Solution Approach 1:
The patent converts harmful phosphorous-based fire retardants into beneficial potassium citrate and other safe biochemical alternatives. These alternatives provide equivalent fire suppression functionality while eliminating the harmful environmental pollution and health hazards associated with phosphorous compound decomposition.
Solution Approach 2:
The patent changes the chemical parameters from phosphorous-based compounds to potassium citrate and naturally-derived biochemicals. This parameter change maintains fire suppression reliability while eliminating harmful environmental factors, as the new chemicals decompose into harmless substances rather than producing toxic gases.
4Reliability
If thick firebreak barriers are created, then fire spread is blocked, but the complexity and resource requirements increase
Solution Approach 1:
The patent uses thin film fire-retardant compositions that form protective coatings on combustible surfaces. These thin films provide effective fire spread blockage without requiring thick physical barriers, thereby reducing the complexity and resource requirements for firebreak creation while maintaining reliable fire protection.

AI summary
Environmentally-clean wildfire inhibitor liquid biochemical solutions produced from an aqueous mixture of alkali metal salt derived from a non-polymerized saturated carboxylic acid such as benzoic acid, and dissolved in water along with a dispersing and coalescing agent, realized as an ester of a non-polymerized saturated carboxylic acid, and dissolved in the water to provide a liquid fire inhibitor solution that can be sprayed on combustible surfaces to form thin alkali metal salt crystalline coatings on the combustible surfaces when and as water molecules in the liquid fire inhibitor evaporate to the environment during drying operations, to inhibit fire ignition, flame spread and smoke development.
