Aboveground Double Walled Fire Rated Tanks
In the United States, if you store over 250 US gallons of fuel aboveground for commercial purposes you must ensure:
UNITY SHIELD FIRE RATED TANKS REMOVE THE NEED FOR BUND WALL CONSTRUCTION AND REDUCE SEPERATION DISTANCES
Bunded areas should be sized to hold 110% of the capacity of the largest storage tank and are traditionally constructed from concrete or masonry adding to project costs and build times.
All SHIELD fire rated fuel storage tanks are manufactured using a steel double-walled construction, essentially a tank within a tank, and fireproofed to give a 4-hour fire rated protection rating as standard.
This integral secondary containment system creates an internal self-bunded solution and ensures traditional bund wall containment areas are no longer required.
SHIELD FIREGUARD Double-Walled Tank = 100% Steel Primary Tank + 10% Fireproof insulated interstitial space + Secondary Mild Steel Outer Tank which equates to a bunded area of 110% of the storage tanks capacity.
Each tank is constructed with a minimum 3” interstitial space around the primary tank and filled with a lightweight, monolithic and highly efficient fireproof material. This protects the primary tank and contents in the unlikely event of a fire or extreme heat.
This complies with all secondary containment requirements for aboveground storage tanks (AST) and UL 2085 which is intended to limit the heat transferred to the primary tank during a fire and to protect the tank from physical damage.
OUR SHIELD FIREGUARD TANKS COMPLY WITH ALL STATE AND FEDERAL ABOVEGROUND STORAGE TANK REGULATIONS
UL standard, UL 2085 references a tank construction intended to limit the heat transferred to the primary tank when the construction is exposed to a 2-hour hydrocarbon pool fire.
Our SHIELD fire rated tanks not only passed the UL 2 hour fire test but exceeded it with a consistent 4-hour fire rating as standard. It has also be designed to provide additional protection to the primary tank against projectile impact and vehicle impact.
SHIELD fire rated tanks are built to Underwriters Laboratories, UL-142 and UL 2085 specifications and carry the FIREGUARD® certification mark. They also also meet the CARB, California Air Resource Board, testing requirements for air emissions and are built in accordance with the Steel Tank Institute’s F-941 standard.
SHIELD FIREGUARD® UL-2085 construction standard meets and exceeds all the requirements set forth by UL-2080 for Fire Resistant Tanks.
The Hazardous Materials Code from the National Fire Protection Association (NFPA) outlines fundamental safeguards for the storage, use, and handling of flammable and combustible liquids and hazardous materials in and around all occupancies and facilities within a commercial environment.
Safeguards such as defined minimum separation distances between fuel storage areas and buildings or public areas. However, practical on-site conditions can challenge these minimum separation distances and in doing so, break NFPA guidelines. That is how a SHIELD FIRE RATED TANK can help.
Due to the high fire-resistant nature of the SHIELD fire rated tanks, they can be positioned within recommended minimum separation distances. In doing so, they provide an incredibly practical and cost effective fuel storage solution in confined areas.
Of course, all applications have to be accessed on an individual basis but to date, our SHIELD fire rated tanks have provided many a workable solution on site.
