Protected Above Ground Storage Tanks
Fireguard® is a registered trademark of the Steel Tank Institute (STI).
Selecting an above ground fuel storage tank involves more than simply choosing the right capacity. The level of fire protection, environmental protection, installation requirements, and long-term durability should all be considered before making a decision.
A UL 2085 Fireguard® tank is one of the most protective above ground fuel storage systems available. It combines a steel primary tank, an outer steel containment tank, and fire-resistant insulation into one factory-built unit. This design helps protect the stored fuel while also providing secondary containment and added fire resistance.
Protected fuel storage tanks are commonly selected for locations where dependable fuel storage is essential. Hospitals, emergency generator systems, municipalities, fleet operations, and industrial facilities often use these tanks because they combine several important safety features into one complete storage system.
If your project requires additional fire protection, or if your local Authority Having Jurisdiction (AHJ) requires a protected tank, a UL 2085 Fireguard® tank may be the right choice.
What Is a UL 2085 Fireguard® Tank?
A UL 2085 Fireguard® tank is a protected above ground storage tank that has been tested and listed to the UL 2085 standard. It is designed to safely store a wide variety of flammable and combustible liquids while providing additional protection beyond a standard above ground storage tank.
These tanks are commonly used for storing:
- Diesel fuel
- Gasoline
- Biodiesel
- Aviation gasoline (Avgas)
- Jet A fuel
- Waste oil
- Other compatible flammable and combustible liquids
Unlike a standard UL 142 above ground storage tank, a UL 2085 Fireguard® tank is built with several additional protective features that improve both fire resistance and environmental protection.
These features include:
- Double-wall steel construction
- Built-in secondary containment
- Fire-resistant insulation
- Enhanced impact resistance
- Enhanced ballistic resistance
- Reduced heat transfer during an external fire
Together, these features help make UL 2085 tanks one of the safest options available for above ground fuel storage.
Benefits of a UL 2085 Fireguard® Tank
Superior Fire Protection
The biggest advantage of a UL 2085 Fireguard® tank is its ability to provide increased fire protection.
The insulation located between the inner and outer steel tanks helps slow the transfer of heat during an external fire. This additional protection can provide valuable time for emergency responders while helping reduce the amount of heat reaching the stored fuel.
Because of this added protection, UL 2085 tanks are frequently specified by engineers, architects, insurance providers, and local fire officials for projects where fire safety is especially important.
Built-In Secondary Containment
Every UL 2085 Fireguard® tank includes an outer steel tank that surrounds the primary storage vessel.
If the inner tank were ever damaged, the outer containment tank is designed to capture the product and help prevent fuel from reaching the surrounding environment. Built-in secondary containment may also reduce the need for separate containment structures depending on local regulations.
Long Service Life
UL 2085 tanks are built from heavy-duty steel and are designed for many years of dependable service. With routine maintenance and periodic inspections, these tanks continue to provide reliable fuel storage for commercial, industrial, agricultural, and government facilities.
Their durable construction allows them to perform well in demanding environments where dependable fuel storage is critical.
Easier Installation
Unlike many concrete vault systems, UL 2085 Fireguard® tanks arrive at the job site as complete factory-built units.
Because the system is already assembled, installation is often faster and less complicated. This can reduce labor, minimize site preparation, and simplify the overall installation process while providing a compact storage solution.
