Solution Overview
Problem
Current methods for cleaning and decontaminating firefighting equipment are ineffective in removing carcinogen toxins, particularly on porous surfaces, and may require costly equipment or generate problematic waste, failing to fully remove hazardous chemicals like benzene and PCBs.
Innovation Solution
A microbiological cleaning formulation comprising an aqueous solution of sporogenous microbial species and nonionic surfactants, which can be blended with additives and solvents, is applied to contaminated surfaces to effectively remove organic carcinogens from firefighting gear and equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If surfactant-based aqueous solutions are used for cleaning, then cleaning action is provided, but wetting characteristics are poor on certain polymeric surfaces
Solution Approach 1:
The patent changes the chemical parameters of the cleaning solution by incorporating specific surfactants and chelating agents that modify the solution's interaction with polymeric surfaces. The formulation includes nonionic surfactants and chelating agents that alter the surface tension and wetting properties, enabling effective cleaning on polymeric firefighting equipment surfaces that were previously difficult to wet and clean.
2Ease of manufacture
If detergent and water preparations are used, then cleaning action is provided, but foams are generated which are problematic for disposal
Solution Approach 1:
The patent employs a biodegradable microbial formulation that decomposes the carcinogens through biological action. The microbial spores and enzymes break down the contaminants into harmless substances, eliminating the need for extensive foam disposal procedures. The formulation itself is designed to be environmentally benign and easily disposed of after use.
3Object-affected harmful factors
If hot air washing is used, then carcinogen removal is achieved, but bulky and costly equipment is required
Solution Approach 1:
The patent replaces the mechanical/thermal hot air washing system with a chemical-biological solution. Instead of using high-temperature air circulation equipment, the invention applies a microbial cleaning formulation that biodegrades carcinogens through enzymatic action. This substitution eliminates the need for bulky hot air washing chambers, filters, and associated equipment, reducing both cost and complexity while maintaining carcinogen removal effectiveness.
4Ease of manufacture
If known cleaning preparations are used, then general cleaning is provided, but porous surfaces are not effectively cleaned
Solution Approach 1:
The patent specifically addresses porous surfaces by incorporating chelating agents and microbial enzymes that can penetrate and bind to contaminants within the porous structure. The formulation includes agents that interact with the porous nature of the surfaces, allowing the cleaning action to reach into and clean the porous matrix where carcinogens accumulate, thereby effectively cleaning porous firefighting equipment surfaces.
5Ease of manufacture
If known cleaning preparations are used, then surface cleaning is provided, but carcinogen toxins are not fully removed
Solution Approach 1:
The patent converts the harmful carcinogen toxins into beneficial substrates for microbial growth. The microbial spores in the formulation use the carcinogens as food sources, breaking them down through metabolic processes. This transforms the harmful contaminants into harmless decomposition products, achieving complete carcinogen removal rather than merely surface cleaning, thereby eliminating cancer risks associated with firefighting equipment contamination.
