UL 142 tanks provide dependable above ground fuel storage for commercial, industrial, agricultural, and municipal operations. Available in single wall and double wall construction, they safely store diesel fuel, gasoline, lubricants, used oil, and many other compatible liquids.
In addition, you can choose from capacities ranging from 185 to 30,000 gallons, along with pumps, gauges, coatings, equipment packages, and other custom options. Whether you need a basic storage tank or a complete fueling system, we’ll help you choose the right tank for your project.
The UL 142 standard, Standard for Aboveground Flammable and Combustible Liquid Tanks, is a nationally recognized safety standard developed and published by UL (Underwriters Laboratories). It establishes construction requirements for above ground steel tanks that store combustible and flammable liquids, helping provide consistent quality and safety.
As a result, many fire marshals, building departments, insurance companies, and other Authorities Having Jurisdiction (AHJs) recognize or require UL 142 tanks for above ground fuel storage. Local requirements vary, so it’s always a good idea to check with the authority overseeing your project.
