UL 142 is a construction standard for steel tanks. |
1) Typically, products complying with a given standard would also comply with all the standards listed
below. As an example, protected tanks would generally meet the requirements for both fire resistant and UL 142 tanks.
2) All of the standards require emergency venting of both the primary tank and secondary containment to assure safe
operation of the tank system in the event of a fire. |
