Abstract: A mobile safety structure for the storing and handling of containers of hrdous materials which comprises 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. The mobile safety structure 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. There is sandwiched between the interior and outer surface steel panels of each wall a pair of gypsum boards and R-19 fiberglass insulation. The fiberglass installation allows the user of mobile safety structure to adapt the structure for use under varying climatic conditions, while the gypsum board provides the structure with at least a four hour fire rating.

Abstract: A storage enclosure for storing containers of hazardous materials with a secondary containment feature being provided by at least one secondary containment shelf suspended from a sub-roof assembly by a plurality of support rods, whereby the secondary containment shelves are suspended within the enclosure free of support from and/or engagement with the side, rear, and front walls, so as to facilitate retention of the containers on the shelves in the event of movement of the unit walls in response to any disturbance, such as in an earthquake, or the like, of the unit. The secondary containment shelf is of a very sturdy construction, employing relatively heavy gauge steel sheets having upstanding, liquid-tight, marginal portions providing a secondary containment of spills or leakage of materials from containers stored on the shelf. Each shelf having at least one drain pipe depending therefrom, for facilitating such spillage or leakage from containers stored thereon.

Abstract: A trailer for transporting an environmentally safe modular storage unit caining hazardous materials over the highways at speeds approaching about fifty five miles per hour. The trailer has a rectangular shaped frame and a hitch assembly extending longitudinally forward from front end of the rectangular shaped frame. The hitch assembly is coupled to a tow truck or other suitable vehicle to allow the trailer and the modular storage unit to be towed from a hazardous material site to a collection or storage site. The trailer is a tandem axle trailer equipped with electrical brakes and a lighting system. The underframe of the trailer includes a tandem axle wheel system which has four wheels and an oil lubricated hub and drums.
