Hazardous Liquid Fire Protection Layout for Localized Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection systems for liquid hazardous materials, such as low-expansion foam, CO2, and aerosol systems, require flooding the entire area, pose safety risks, incur high costs, and are not suitable for localized fire suppression, leading to delays and significant secondary damage.
Innovation Solution
A fire protection system that aligns storage arrangements, containment areas, and extinguishing agent outlets to direct escaped liquid hazardous materials to a containment area, using sprinklers that activate locally and discharge extinguishing agents like water or heavy foam to suppress fires efficiently and immediately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If area-wide flooding with extinguishing agent is used, then fire suppression coverage is improved, but water damage and secondary damage increase significantly
Solution Approach 1:
The patent implements local fire suppression by directing extinguishing agent flow specifically to containment areas where hazardous liquids are collected, rather than flooding the entire storage area. The storage arrangement includes inclined surfaces and channels that guide both the hazardous liquid and the extinguishing agent to a localized containment zone, enabling targeted fire suppression and minimizing water damage to surrounding areas.
2Reliability
If low-expansion foam systems are used, then fire suppression capability is improved, but evacuation time and safety risks increase due to area-wide activation
Solution Approach 1:
The system enables localized fire suppression by confining the extinguishing agent discharge to specific containment areas rather than activating the entire storage area. This allows for immediate fire response without requiring personnel evacuation, as the hazardous zone is isolated to the containment area where the extinguishing agent is discharged.
3Reliability
If CO2 or aerosol systems are used, then fire suppression effectiveness is improved, but installation and maintenance costs increase
Solution Approach 1:
The patent utilizes a water-based hydraulic system with pumps, pipes, and nozzles to deliver extinguishing agent to containment areas. This approach replaces complex CO2 or aerosol systems with a simpler, more cost-effective hydraulic infrastructure that can be integrated into existing storage facility plumbing, reducing both installation and maintenance costs while maintaining fire suppression effectiveness.
4Volume of moving object
If storage containers are positioned at height, then storage space utilization is improved, but fire protection access and response time deteriorate
Solution Approach 1:
The patent extracts the fire suppression function from ground-level positioning by implementing overhead sprinkler systems that discharge extinguishing agent directly into containment areas positioned throughout the storage space. This allows storage containers to be positioned at various heights for optimal space utilization, while the extinguishing agent is delivered directly to the containment areas regardless of container position, maintaining rapid response time.

Function Achieved in This Case
Enables localized fire suppression without area-wide flooding, reducing evacuation times, minimizing damage, and lowering installation and maintenance costs, while allowing immediate reuse of unaffected areas.

AI summary
The invention relates to a fire protection system (1, 1') for fire protection for liquid hazardous goods, comprising: at least one storage arrangement (10a, 10b, 10c, 10d) for storing the liquid hazardous goods in at least one storage container (60), at least one collecting region (200), and a first plurality of extinguishing agent outlets (31), wherein the at least one storage arrangement (10a, 10b, 10c, 10d) is designed to direct the liquid hazardous goods into the at least one collecting region (200) when the liquid hazardous goods exit from the at least one storage container (60), and wherein the at least one storage arrangement (10a, 10b, 10c, 10d), the at least one collecting region (200) and the first plurality of extinguishing agent outlets (31) are arranged relative to each other such that in the event of a fire of the liquid hazardous goods, a firefighting action can be carried out by means of a non-hazardous goods extinguishing agent.
