A Guide to Tank Regulations: UL-2085 vs. UL-142

When it comes to on-site fuel storage, safety and compliance are non-negotiable. Purchasing a fuel tank isn’t just about capacity—it also means understanding and complying with the necessary safety standards to keep your storage secure and reliable. Whether you’re managing fuel for a fleet, construction site, or industrial facility, following the right tank regulations ensures safety and environmental protection.

Two of the most common standards for aboveground fuel storage tanks are UL-142 and UL-2085. While both provide necessary protections, they differ in fire resistance, impact durability, and environmental safeguards. This guide breaks down the key differences between UL-2085 and UL-142, outlines regulatory requirements, and offers insights to help you stay compliant and maintain your fuel tank safely and efficiently.

What are the Key Differences between UL-2085 and UL-142?

Fuel tank regulations vary based on the location of the tank, with both standards ensuring secondary containment, safety, and fuel protection. The UL-142 standard is a widely recognized standard for aboveground storage tanks, requiring rigorous testing in materials, design, strength, leakage prevention, and proper labeling. These measures help minimize risks associated with storing flammable liquids, ultimately protecting both the handlers and the fuel quality.

Some jurisdictions and applications require a UL-2085 tanks, which offers enhanced protection. They feature fire-resistant materials between the two walls of the tank, increasing its safety in the event of a fire or ballistic impact.

Why are These Regulations Important?

Understanding the differences between UL-142 and UL-2085 will help businesses select the appropriate fuel tank while ensuring compliance with industry regulations. Following these standards is important for both safety and legal requirements. Other key regulations and requirements to keep in mind when choosing a fuel tank include:

• SPCC Rule (Spill Prevention, Control, and Countermeasure): This EPA regulation mandates facilities to implement spill prevention and mitigation plans.
• State and Local Regulations: Many jurisdictions have specific fuel tank requirements based on national standard, requiring either a UL-142 listing or a UL-2085 listing. Consulting local authorities ensures adherence to all applicable laws.
• Fire Codes: Compliance with fire safety regulations, such as those set by the National Fire Protection Association (NFPA), is necessary. UL-2085 tanks, with their fire-resistant design, may be necessary in areas with stricter fire codes.

How to Determine One Regulation Over the Other

Selecting the right fuel tank standard depends on the installation requirements and the regulations set by the governing authority. UL-2085 tanks are typically required for permanent installations in areas with stricter regulations, such as California, metro city areas, and some coastal markets. Other factors influencing this requirement include the type of site and the tank’s proximity to property lines or buildings.

Considering these variables, businesses that require bulk tanks should consult with their health and safety officer or local regulatory body to ensure they select the appropriate tank for compliance and safety. The variations to consider are:

• Type of site – Different environments, like construction zones, marine facilities, or industrial sites, may have specific safety and regulatory requirements.
• Proximity to infrastructure – Setback distances from roads, property lines, buildings, or other structures can determine the level of fire protection needed.
• Type of liquid stored – The flammability and volatility of the liquid being stored impact the tank requirements and safety measures.
• Local regulations and permitting – Regional fire codes, environmental laws, and zoning restrictions may influence tank selection.
• Consulting safety experts – Businesses should work with health and safety officers or local authorities to ensure compliance with industry regulations and best practices.
