ABSTRACT:
An above ground storage facility for volatile and inflammable liquids which includes a concrete vault formed as a base and cylindrical upstanding walls on or integral with said base. An inner liquid container formed of metal has a metal base resting on ribs of the vault base to space the metal container from the vault base. Cylindrical walls of the liquid container are sealed to and rise from said metal base. The walls of the metal container are spaced inwardly from the inner surface of the vault walls to leave an annular envelope of air around the metal container. A conical roof is secured and sealed to the upper edges of the metal cylindrical walls and the roof has peripheral edges which overlie and are spaced from the upper edges of the concrete wall and the annular air envelope around the steel container. The roof edges are shaped to protect the space between the vault and the container from the elements while allowing air passage from the envelope to the atmosphere to allow escape of condensate which may collect on the steel container or on the inner surface of the vault walls.
