Modular mobile safety structure for containment and handling of hazardous materials

A modular mobile safety structure for housing containers of hazardous materials and providing sump-type secondary containment for receiving spillage and leakage of said hazardous materials from said containers that are housed within said modular mobile safety structure, said modular mobile safety structure comprising:

• (a) first and second modular storage units, said first modular storage unit being positioned adjacent said second modular storage unit and secured thereto to form a tandem arrangement of modular storage units for treatment and handling of said hazardous materials, said first and said second modular storage units each comprising:
• (i) a rectangular shaped base assembly including a framework of a welded assembly of steel components, said framework of said base assembly comprising:
• (A) a pair of front and rear support members and a pair of side support members that are arranged end to end to define a rectangular shaped structure, a first group of four corner fittings having first and second orthogonally disposed sides, a top portion and a bottom portion, each end of each of said side support members being attached to the first side of a separate one of said first group of four corner fittings and each end of each of said front and rear support members being attached to the second side of a separate one of said first group of four corner fittings;
• (B) a pair of inverted T channel support members disposed substantially parallel to said front and rear support members, one end of each of said inverted T channel support members being attached to one of said side support members and an opposite end of each of said inverted T channel support members being attached the other of said side support members, each of said inverted T channel support members having a base channel member and a floor support channel member mounted on a top portion of said base channel member;
• (C) first and second floor support members respectively attached to an inner side of said front support member and an inner side of said rear support member;
• (D) a first generally rectangular shaped steel plate mounted on a bottom portion of said front, rear and side support members and a bottom portion of the base channel support member of said pair inverted T channel support members wherein said first generally rectangular shaped steel plate mates with said front, rear and side support members forming a substantially rectangular open secondary container that is leakproof, said open secondary container receiving spillage and leakage of said hazardous materials from said containers that are housed within each of said first and said second modular storage units;
• (E) a removable grating type floor supported by said base assembly and resting upon said first and said second floor support members and the floor support channel members of said pair of inverted T channel support members, said removable grating type floor extending substantially horizontally atop said open secondary container;
• (ii) inner and outer side walls extending perpendicularly upward from said base assembly, a rear wall extending perpendicularly upward from said base assembly and a front wall extending perpendicularly upward from said base assembly, one end of each of said inner and said outer side walls being secured to a separate one of the opposed ends of said front wall and the other end of each of said inner and said outer side walls being secured to a separate one of the opposed ends of said rear wall to form a rectangular shaped assembly of upstanding walls;
• (iii) a rectangular shaped roof mounted atop said rectangular shaped assembly of upstanding walls and extending horizontally over an interior space that is defined between said front and rear walls and between said inner and said outer side walls;
• (iv) each of said front, said rear and said inner and said outer side walls and said roof comprising:
• (A) a rectangular shaped framework of structural steel support members, at least one outer wall panel mounted to an outer surface of said rectangular shaped framework, an inner wall panel mounted to an inner surface of said rectangular shaped framework, a pair of stack sheets of gypsum type board sandwiched between said at least one outer wall panel and said inner wall panel, said pair of stack sheets of gypsum board being secured to said inner wall panel, and a fiberglass insulation material interposed between said pair of stack sheets of gypsum type board and said at least one outer wall panel;
• (B) said pair of stack sheets of gypsum type board within each of said front, rear and side walls and said roof providing for a fire rating of at least four hours for said modular mobile safety structure and said fiberglass insulation material allowing said modular mobile safety structure to be adapted for use under varying climatic conditions;
• (C) the rectangular shaped framework of said roof having a second group of four corner fittings wherein a first and a second of said second group of four corner fittings are positioned at a top edge region of the inner side wall of said first and said second modular storage units
• (D) a first and a second of said first group of four corner fittings being positioned in proximity with a bottom end region of the inner side wall of said first and said second modular storage units;
• (b) a first pair of container conlinks for coupling the first and the second of said second group of four corner fittings of said first modular storage unit to the first and the second of said second group of four corner fittings of said second modular storage unit;
• (c) a second pair of container conlinks for coupling the first and the second of said first group of four corner fittings of said first modular storage unit to the first and the second of said first group of four corner fittings of said second modular storage unit;
• (d) said inner side wall of said first and said second modular storage units having a bellows support frame, the bellows support frame of the inner side wall of said first modular storage unit being aligned with the bellows support frame of the inner side wall of said second modular storage unit when said first modular storage unit is positioned adjacent said second modular storage unit to form said tandem arrangement of modular storage units;
• and
• (e) a bellows having one end thereof connected to the bellows support frame of the inner side wall of said first modular storage unit and an opposite end thereof connected to the bellows support frame of the inner side wall of said second modular storage unit, said bellows allowing access between said first modular storage unit and said second modular storage, said bellows being removable from the bellows support frame of the inner side wall of said first and said second modular storage units.
