Fire Wall Isolation for Aboveground Fueling Station Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Above-ground fueling stations face safety concerns due to the potential for fuel fumes and leaks when the vending/pumping section is oriented close to the fuel storage tank, especially with the presence of electricity and sparks, and there is a need for efficient resource use and space allocation.
Innovation Solution
A double-walled storage tank surrounded by fire-rated panels with an internal fire wall to isolate the dispenser section from the fuel storage section, creating a fuel supply chamber that enhances safety by reducing the risk of fires and explosions, and allows for secure, unattended operation using credit/debit card payments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the vending/pumping section is oriented close to the fuel storage tank, then space allocation is efficient and energy consumption is reduced, but safety risk increases due to potential fuel leaks and fumes near electricity and sparks
Solution Approach 1:
The facility is divided into separate sections: a dispensing section for fueling operations and a storage section for fuel tanks, connected by a protected supply chamber. This segmentation allows close proximity for efficiency while maintaining safety through physical separation of hazardous functions.
Solution Approach 2:
A supply chamber with fire-resistant walls acts as an intermediary zone between the dispensing section and storage section. This intermediate structure contains fuel supply piping and provides a fire barrier, enabling close spacing while preventing direct exposure of fuel storage to ignition sources in the dispensing area.
2Use of energy by moving object
If the vending/pumping section is oriented close to the fuel storage tank, then energy consumption is reduced, but safety risk increases due to potential fuel leaks and fumes
Solution Approach 1:
The facility is divided into separate sections: a dispensing section for fueling operations and a storage section for fuel tanks, connected by a protected supply chamber. This segmentation allows close proximity for efficiency while maintaining safety through physical separation of hazardous functions.
Solution Approach 2:
A supply chamber with fire-resistant walls acts as an intermediary zone between the dispensing section and storage section. This intermediate structure contains fuel supply piping and provides a fire barrier, enabling close spacing while preventing direct exposure of fuel storage to ignition sources in the dispensing area.
3Reliability
If fire resistant panels and protective structures are added, then safety is improved, but device complexity increases
Solution Approach 1:
The supply chamber combines multiple functions: it serves as a protective enclosure for fuel supply piping, a fire barrier between dispensing and storage sections, and a structural element that can support the canopy. This merging reduces overall complexity compared to separate protective structures for each function.
Solution Approach 2:
The fire-resistant supply chamber structure serves multiple purposes: protecting fuel supply infrastructure, providing fire separation, and potentially supporting the canopy structure. This multi-functionality reduces the number of separate protective elements needed, simplifying the overall design.

AI summary
An aboveground fueling facility for storing and dispensing a combustible fluid such as gasoline includes a double-wall storage tank provided in a fuel storage section where the tank is constructed and arranged to store the combustible fluid in a fire resistant tank and box. The facility further includes a dispenser section for dispensing the fuel and an isolating wall which separates the fuel storage section from the dispenser section. The isolating wall is preferably a fire wall and in part defines a fuel supply chamber. An access door provides access for a person to enter or exit the fuel supply chamber. A user may obtain self-service of fuel at the dispenser section which may also be secured by a door. Fire resistant panels are also used as the exterior box structure for the facility and also provide a display or advertising function.
