UL 2085 Fireguard® Specification
Fireguard®, a Fire-Rated, Lightweight Double Wall Steel Aboveground Storage Tank.
The Fireguard® Thermally Insulated Aboveground Storage Standard is based on the application of sound engineering principles and the combined experience of STI membership, which includes state of-the-art manufacturing considerations. It represents a composite of input from users, regulatory authorities, manufacturers, and consultants. Fireguard® represents the second generation of thermally protected aboveground storage tanks with its unique double wall and insulated design. Other designs have relied upon costly, heavy materials such as concrete to provide secondary containment and insulation. However, Fireguard® uses three inches of lightweight monolithic thermal insulation between the two walls of steel to minimize heat transfer from the outer tank to the inner tank.
The thermal insulation material is a composition of perlite, cement, water and special ingredients carefully mixed to standardized proportions. The light weight of the completed tank unit eases relocation on projects that demand additional fire protection.
The Fireguard® design responds to the latest demands of the fuel and chemical storage marketplace where fire-rating, environmental safety and relocation are primary concerns.
The Fireguard® fuel-storage design provides secondary containment to prevent spillage or pool fires as well as both thermal insulation and emergency venting for a two-hour fire rating. A two-hour fire rating signifies that the structural integrity of the tank will not be compromised, for at least two hours, if a fire were to surround the tank system. The secondary containment provides 110 percent containment of the primary tank’s capacity.
The steel outer wall of the tank is coated to prolong the Fireguard® tank’s weather resistance and to further reduce maintenance needs.
Fireguard® tanks are built in accordance with Steel Tank Institute Publication No. F941, “Standard for Thermally Insulated Above-ground Storage Tanks.” Tank capacities can be specified from less than 200 gallons to 5000 gallons. Smaller capacities typically provide greater ease of relocation.
Fireguard is a registered trademark of the Steel Tank Institute. Fireguard tanks are built by licensed members of STI.
