Description
FIELD OF THE INVENTION
[0001] The present invention relates to storage tanks, and more particularly to storage tanks with redundant containment structures for containing hazardous materials.BACKGROUND OF THE INVENTION
[0002] Storage tanks are used throughout the world for a variety of purposes. One of the more significant uses for tanks of this type is for the containment of fuels for use at the location of the tanks, such as to store diesel fuel for emergency power diesel engine generator sets. With hazardous materials such as fuels, it is necessary to provide certain safeguards for the storage tanks to protect the environment from a tank leak. These safeguards are normally the requirements of the authority having jurisdiction that necessitate these tanks have the capability for secondary containment of any liquid that could leak from the primary or inner tank.
[0003] As best shown in FIGS. 1 and 2, an example of a prior art containment tank 10 on which can be mounted a generator 1000, a...

Embodiment Construction
[0023]With reference now to the drawing figures in which like reference numerals designate like parts throughout the disclosure, a containment tank constructed according to the present invention is illustrated generally at 100 in FIG. 3. The tank 100 is constructed similarly to the prior art tank 10 with an inner tank 112 and an outer tank 114. The outer tank 114 that can be utilized in the construction of the container tank 100 can be virtually the same as that used in the prior art tank 10, with a bottom wall 116 and a number of side walls 118 formed from a suitable metal material and secured to one another to form a fluid-tight seal between the respective walls, such as by welding. The side walls 118 each include a central panel 120, a lower flange 122 and an upper flange 124, with the lower flange 122 affixed to the side of the bottom wall 116. The lower flange 122 and the upper flange 124 are joined at each end by an end plate 126, and between the end plates 126 by a number of ...
