Vertical Configurations: These are steel atmospheric tanks intended for aboveground storage of non-corrosive, stable, flammable, and combustible liquids that have a specific gravity not exceeding that of water. Maximum allowable working pressure is 0.5 psig as measured from top of tank. Vertical tanks may be of single or double wall construction. If the tank is a double wall configuration, then it has interstitial monitoring capabilities.
These tanks may also be built with or without multiple compartments for multiple fuel storage. Tanks generally have flat bottoms and conical roofs. Only new materials are used in tank construction. Each tank is sized with the appropriate normal and emergency vent openings as defined in the tank’s standard of construction. Tanks are built to Underwriters Laboratories specification standard UL-142.
