Choosing the right fuel tank isn’t always straightforward. Tank selection depends on a variety of factors, from the conditions and accessibility of the site to the required volume of fuel storage.  In certain situations, you’ll need a fuel tank that offers an added layer of security – that’s where the UL2085 tanks come in.

Rather than viewing a fuel storage tank with UL2085 as a universal requirement, it’s helpful to understand the situations where you can make the most of their unique features and use them for risk mitigation.

What Is a UL2085 Tank?

UL2085 is a certification standard for protected aboveground storage tanks used to store flammable and combustible liquids. To achieve certification, a UL2085 fuel tank must meet stringent performance requirements related to fire protection, impact resistance, and ballistic resistance. 

Key characteristics typically include:

• Double-wall construction with integrated secondary containment
• Thermal insulation designed to limit heat transfer during a fire
• Two-hour fire resistance testing
• Impact resistance testing
• Ballistic resistance testing

These requirements distinguish UL2085 tanks from standard aboveground storage solutions that may not provide the same level of protection.

5 Reasons to Consider a UL2085 Tank

A tank with UL2085 certification is a specialist storage solution best deployed in situations where flammable liquids may be at risk, requiring sufficient protection. Here are some of the most common on-site and transport situations where UL2085 is useful. 

1. Proximity to Buildings and Valuable Assets

Not every site has the luxury of placing fuel storage far away from people, equipment, or buildings. It’s important to consider where your fuel tank will and can be safely placed relative to nearby structures, equipment, or operations.

Urban projects, industrial facilities, utility sites, and constrained construction locations often face space limitations. In these environments, decision-makers frequently evaluate whether a protected tank design offers advantages compared to other storage options.

Ideally, fuel storage should be placed within access of the active areas across your site, so refueling can be completed easily and efficiently, and away from potential hazard areas. If you’re working in a confined space with restricted access options, it’s key to consider the risk of fire and damage to buildings, high-value equipment and critical infrastructure. In this situation, the additional fire and impact protections of UL2085 tanks make them a more complete solution for the task. 

2. Fire Risk Considerations

Every fuel storage application carries some level of fire risk, but certain environments may warrant greater scrutiny and the added security a UL2085 tank offers.

Factors that may increase the risk of fire include:

• Areas with heavy equipment activity
• Locations where large volumes of flammable liquid are stored
• Sites located close to ignition sources
• Facilities where fuel availability is operationally critical

UL2085 tanks incorporate insulation and are subjected to fire-performance testing that goes beyond the requirements of many conventional aboveground tank designs.

3. Exposure to Vehicle Traffic or Physical Impact

As a byproduct of their functionality and necessity of access on busy job sites, fuel tanks are often positioned in busy operating environments.

High-density construction projects, fleet facilities, equipment yards, and industrial sites can subject tanks to elevated risks from:

• Trucks
• Forklifts
• Heavy machinery
• Site traffic

Tanks with UL2085 certification have also been tested against impact-resistance requirements intended to evaluate how they perform under physical stress scenarios.

4. Security, Damage Prevention, and Meeting Legal Requirements 

Fuel is a valuable asset, and storage systems are increasingly expected to protect both the fuel itself and the equipment attached to the tank.

While security features vary by manufacturer, many organizations evaluating fuel infrastructure consider:

• Protection from accidental damage
• Protection from intentional tampering
• Protection of hoses, pumps, and ancillary equipment
• Fuel-loss prevention

These concerns often become part of the broader conversation when reviewing higher-protection tank options.

Additionally, local codes, insurance requirements, and regulations can vary significantly depending on your location and project type.

5. Critical Operations

Some facilities simply cannot afford fuel interruptions. When working on critical sites and scenarios such as hospitals, data centers, emergency response facilities and utility infrastructure, safe and secure access to fuel is critical. 

In these applications, the consequences of fuel loss can extend well beyond the value of the product itself. The ability of a storage system to continue protecting fuel during adverse events becomes an important consideration.

UL2085 vs. “Fireguard®” – Understanding the Terminology

A common source of confusion is the use of the term “Fireguard® tank.”

Fireguard® is a trademarked product name, while UL2085 is the certification standard. If a specification, jurisdiction, or project stakeholder references a “Fireguard® tank,” the underlying requirement is often related to the tank meeting UL2085 protected tank criteria.

Understanding this distinction can help simplify conversations around fuel storage requirements and help you choose the right product.

A Solution for Every Situation with Western Global

There is no universal trigger that automatically determines when a UL2085 tank is the best tank for the job. The decision is typically influenced by a combination of factors, including:

• Site layout
• Proximity to buildings and operations
• Fire exposure concerns
• Impact risks
• Fuel security considerations
• Business continuity needs
• Local regulatory and stakeholder requirements
