Abstract

A mobile safety structure for the storing and handling of containers of hrdous materials comprising multiple modular storage units. The modular storage units may be configured in tandem to form one embodiment of the modular mobile safety structure. In this configuration access between the interiors of adjacent modular storage units is provided by a bellows which is connected to and removable from a bellows support frame in a side wall of each modular storage unit. The modular storage units may also be configured in a stacked arrangement to form an alternate embodiment of the modular mobile safety structure. In this configuration access between the interiors of the stacked modular storage units is provided through an opening between units in the stack. A pull down safety ladder affixed to the roof assembly of all units except the top unit in the stack allows the user to gain access to each unit in the stack of modular storage units. Each modular storage unit includes a secondary containment feature in the form of a base assembly having a containment pan. The base assembly also provides a framework for supporting a floor of removable grating which allows access to the containment pan. Each modular storage unit further comprises front, rear and side walls and a roof of very sturdy construction employing interior and outer surface steel panels supported by a generally rectangular shaped tubular steel framework for each wall and the roof of the mobile safety structure.
