Fireguard UL 2085 Fire-Protected Aboveground Tanks

Compliance Made Simple with Newberry

The Fireguard UL 2085 tank is a thermally insulated, double-wall, fire-protected aboveground storage tank built to STI/SPFA specification F941. A layer of monolithic insulation between the primary and secondary walls gives the tank a two-hour fire rating, so it keeps the fuel inside below a safe temperature even in a hydrocarbon pool fire. Every Fireguard is built by an STI-licensed fabricator under an independent, third-party quality-control program. With a century-long track record and some of the fastest lead times in the U.S., Newberry ships the size you need when you need it.

How a Fireguard tank works

Fireguard is a tank-within-a-tank. A steel primary tank holds the fuel; a steel secondary tank surrounds it; and the space between the two walls is filled with a lightweight monolithic insulation. That insulation is what earns the two-hour fire rating: in a fire it slows heat transfer to the primary tank, while the sealed interstitial space provides both secondary containment and a path for leak monitoring. The result is a single tank that satisfies fire protection, spill containment, and leak detection at once, without a separate dike or vault.

Fire protection and UL 2085

UL 2085 is the standard for protected aboveground tanks. To carry the listing, the complete tank assembly is fire-tested, hose-stream tested, and impact tested, and Fireguard is also projectile (ballistics) resistant when built to the required steel thickness. F941 tanks are tested and listed under UL 2085, ULC-S655, or SwRI 93-01, and are intended for installation under NFPA 30, NFPA 30A, NFPA 31, or the International Fire Code.

Two-hour fire rating verified by full-scale furnace testing
Hose-stream resistant and vehicle-impact resistant construction
Projectile (ballistics) resistant when specified
A 4-hour fire rating is available under SwRI 93-01 with 6-inch insulation

UL 2085 Applications

Fireguard tanks suit sites that need fire-rated fuel storage in tight or occupied areas: fleet fueling, bulk oil and lubricant storage, backup-generator supply, fuel farms, and commercial or industrial sites where local fire code requires a protected aboveground tank rather than a plain double-wall. The insulated, impact-resistant design is what lets these tanks sit closer to buildings and property lines than a standard UL 142 tank.

FAQ

A Fireguard UL 2085 tank is a thermally insulated, double-wall aboveground fuel tank with a two-hour fire rating. A layer of monolithic insulation between the steel primary and secondary tanks protects the fuel from heat in a fire, while the double wall provides built-in secondary containment. It is built to STI specification F941 and listed to UL 2085.

UL 2085 is the standard for protected aboveground storage tanks. To be listed, the whole tank assembly must pass a two-hour fire test, a hose-stream test, and a vehicle-impact test. It is the standard fire marshals and codes reference when a fuel tank needs to sit near buildings, occupied areas, or property lines.

A UL 142 tank is a standard steel aboveground tank, single or double wall, with no fire rating. A UL 2085 tank like Fireguard adds
monolithic thermal insulation insulation and fire, impact, and hose-stream testing for a two-hour fire rating. Where local code requires fire-protected storage, UL 2085 is specified; where it does not, UL 142 may be enough.

Standard Fireguard tanks carry a two-hour fire rating under UL 2085. A four-hour rating is available as an option under the SwRI 93-01 standard, which requires six inches of insulation; contact Newberry to specify it.

Newberry offers Fireguard UL 2085 tanks from 300 to 20,000 gallons, with inner-tank dimensions and approximate weights listed for each size. You can size a tank to your fuel volume with the Tank Chart Calculator.

No. The double-wall design is the secondary containment. The sealed space between the primary and secondary tanks contains any leak from the primary and can be monitored, which meets EPA SPCC secondary-containment requirements without a separate dike or vault.

Yes. UL 2085 listing requires the tank to pass a vehicle-impact test, and Fireguard tanks are also projectile (ballistics) resistant when built to the required steel thickness. This is part of why they can be installed in exposed or high-traffic locations.

Fireguard tanks are built to STI specification F941 and listed to UL 2085 (or ULC-S655 / SwRI 93-01), built to UL 142 and NFPA 30 and 30A, and meet IFC and CARB standing-loss-control air-emission requirements. They are intended for installation under NFPA 30, 30A, 31, or the International Fire Code.
