AGI Westeel Fireguard® Horizontal Dual Wall ULC and UL Certified Fuel Tanks are fully contained, protected and fire rated ULC or UL certified horizontal storage solution, that are also fully customizable to fit any fuel storage application.

AGI Westeel’s licensed ULC S655 and UL 2085 Fireguard® tanks are dual-wall fire-protected above ground storage tanks typically used where setback limitations or regulatory requirements restrict the use of traditional dual wall tanks. Fireguard® tanks feature inner and outer steel tanks with a unique lightweight thermal insulation material that exceeds the ULC/UL 2-hour fire test in a 2,000°F rapid rise furnace while maintaining 75% less weight than traditional concrete. The insulating material is also 75% lighter than concrete, reducing shipping, installation and relocation costs.

Additional features include ballistics protection – where ammunition fired from a .30 caliber rifle will not penetrate the primary tank at 30.5 meters – and impact protection – where the tank has a tested ability to prevent leakage of the primary tank when hit by a 5,455 kg weight moving at 16 km/h, 450 mm above grade. Fireguard® tanks are the only tanks that meet all these standards: ULC S655 and UL 2085 listed “protected” tanks Ballistics and impact protection Both inner and outer steel tanks are built to ULC/UL standards NFPA 30 and 30A International fire code Canadian fire code California Air Resources Board standing loss control testing requirements for air emissions STI Standard F941 for Thermally Insulated Above Ground Storage Tanks Fireguard® tanks are not simply a concrete encased tank. The external tank wall both ensures dual containment and protects the insulation from the elements, eliminating cracking and flaking commonly found in concrete-encased tanks.
