What is UL142?
UL142 is a widely recognised safety standard for aboveground tanks. Published by UL, the standard sets out the requirements for the design and construction of steel atmospherics storage tanks intended to store non-corrosive, stable flammable and combustible liquids such as diesel & gasoline. Only tanks approved by UL’s testing and inspection regime can be marked accordingly.
What is UL2085?
UL2085 is a safety standard for Protected Aboveground Tanks for Flammable and Combustible Liquids. A Protected tank is intended to limit the heat transferred to the primary tank during a 2hr fire and protect the tank from physical damage. Typically, this is achieved by adding an insulating material between the inner and outer tank wall. UL2085 tanks can be optionally tested for ballistic protection and vehicle impact, and where these tests have been completed, they are marked accordingly.
What are the main differences between the two approvals?
The major difference between a UL2085 and a UL142 tank is the addition of insulation or other reinforcing materials to create a Protected Tank. A Protected Tank will limit the heat transferred to the inner tank during a fire. The other materials of construction and shop test procedures are broadly aligned between the two standards. However, the addition of insulation material and reinforcement in a UL2085 tank can make the tanks heavy and cumbersome to move if relocation is required.
Why would I as a customer need to consider these approvals?
To ensure the safety and compliance of your fuel tank installation. Compliance can be complex to navigate, and you may need to consider local regulations. Dependent on the situation, the local authority having jurisdiction will require compliance with recognised fire safety codes such as NFPA30, NFPA30A or the International Fire Code. Helpfully, both UL142 and UL2085 listed storage tanks are recognised by these fire safety codes.
What sorts of situations would I as a customer need one approval over the other?
The correct approval will come down to the specific installation and the authority having jurisdiction. Typically, UL2085 tanks are required where there is a permanent installation that has a higher fire risk. This risk could be dictated by factors such as the type of site (construction site vs a marina), setback distances to roads, property lines or buildings or even the liquid being stored. Customers should consult with their health and safety officer if they are unsure as to which type of tank to choose.
