When safeguarding flammable materials in wildfire-prone areas, selecting the right fuel storage tank is critical. Fuel storage systems must be fire-resistant, structurally reliable, and compliant with federal and state regulations. Among the most widely recognized standards in the fuel storage industry are UL-142 and UL-2085. While both carry Underwriters Laboratories certification, they serve different purposes and offer distinct safety benefits—especially in environments where fire hazards are prevalent.
Understanding UL-142 Fuel Tanks
UL-142 tanks are steel aboveground tanks intended for the storage of flammable and combustible liquids. These tanks are single-wall or double-wall and typically used for:
- Diesel fuel
- Gasoline
- Waste oil
- Solvents and chemicals
Key features of UL-142 tanks:
- Constructed from carbon steel
- Designed for easy installation and inspection
- Often cost-effective
- Require additional containment measures for fire protection
However, UL-142 tanks are not inherently fire-resistant. While durable, they need secondary containment systems or fire-resistant barriers when used in wildfire zones. This makes them a less favorable choice in regions such as California, Colorado, and Arizona, where fire safety standards continue to evolve.
What Makes UL-2085 Tanks Fire-Rated?
UL-2085 tanks, also known as "protected" tanks, are specifically engineered to resist extreme temperatures, including direct flame exposure. These tanks feature:
Thermal insulation: Two layers of steel encase an insulating material that helps deflect radiant heat and flames.
Impact resistance: Designed to withstand vehicle impacts and projectile hazards.
Secondary containment: Built-in containment to protect against leaks.
Applications best suited for UL-2085 tanks include:
- Commercial fueling stations in fire-prone areas
- Emergency generator fueling
- Military and municipal fuel storage
- Remote construction sites
Because of their design, UL-2085 tanks offer superior protection in areas subject to wildfires or industrial fire risks, aligning with regulations set by the EPA and local fire authorities.

Why UL-2085 Tanks Are Preferred for Fire Zones
In high-risk environments, the margin for error is slim. UL-2085 tanks provide:
- Reduced risk of ignition during wildfires
- Extended fuel storage integrity during natural disasters
- Compliance with stringent NFPA and state-level codes
- Enhanced environmental protection through spill containment
For industrial operators, municipalities, and contractors working in wildfire-affected regions, investing in a UL-2085 tank is a proactive risk mitigation strategy.
