Setbacks for Aboveground Tanks Used for Public Access Vehicle Fueling - See PDF for table PDF
1A vaulted tank is one placed in a liquid-tight concrete enclosure consisting of 4 walls, a top and a bottom that completely encloses the tank and provides protection from physical damage and limits heat transfer from a high intensity liquid pool fire.
2 A protected tank is a listed and labeled system that consists of a primary tank along with integral secondary containment which provides protection from physical damage and limits heat transfer from a high intensity liquid pool fire. Systems listed as complying with UL 2085 or an equivalent standard are considered protected tanks.
3 A fire-resistant tank is a listed and labeled primary tank with or without integral secondary containment that provides protection from heat transfer from a high intensity liquid pool fire. Systems listed as complying with UL 2080 or an equivalent standard are considered fire-resistant tanks.
