Abstract: The present invention, in its most elemental form, comprises an above ground storage vessel for volatile liquids in which an inner storage chamber is formed in proportion to an outer shell, leaving a space between them which is capable of containing up to 110% of the storage capacity of the inner storage chamber, which chamber is completely encapsulated in a volume of a non-conductive particulate medium of a type which has the capacity to entrap up to 45% of its volume of the storage vessel within its boundaries, and which is sufficiently compactible as to be capable of supporting the entire storage vessel and its contents centrally within the confines of a protective outer shell.
