A tank for transporting fluids on a truck chassis includes a front wall, side walls, a back wall, a top, and a floor. Interior stairs extend from the floor to an opening in the top to allow stair access into the interior with integrated safety handrails on the fill port cover. Stair toe kicks act as internal transverse baffles to help control fluid motion and surging. The stairs also act as a structural stiffener between longitudinal baffles. Horizontal baffles assist in controlling fluid motion and surging. Formed baffles provide strength and stiffness. A baffle interlocking system improves joint integrity and aids manufacturing. Formed outer skins provide structural strength for the tank. Ports located in front and rear bulkheads may be used for tank ventilation or, depending on local safety codes, as secondary access points. Doors or other access openings may be located in the tank bulkheads to provide better interior access.

A trailer that includes a tank with an enclosed interior space configured to hold fluid. The trailer can include a chassis that supports the tank and wheels for moving to desired locations. The tank can include planar opposing sides with rounded corners. One or more baffles can be located within the interior space. The baffles restrict the movement of the fluid within the interior space while the trailer is being moved between locations. This restriction reduces the forces that the moving fluid exerts on the tank which could cause damage to the tank that could result in leaks and failure.

A bulk fluid storage container has a top wall structure and a bottom wall structure held in spaced relation by a side wall structure. An internal baffle assembly is disposed in the fluid storage volume between the side wall structure for reducing fluid sloshing. A fill port formed in the top wall structure has a fill flange for coupling with a source of the fluid. A vent port formed in the top wall structure has a pressure vacuum value. A drain port formed in the side wall structure in a lower region adjacent the gutter region has a drain valve assembly is coupled to the drain port. A frame assembly includes an upper rectangular frame member and a lower rectangular frame member arranged in spaced relation by a plurality of post; wherein the frame assembly surrounds and supports the fluid storage vessel.

The present invention includes systems, assemblies, and methodologies for inhibiting combustion within fluid containers, enhancing the safety of such containers. One aspect includes a novel base module from which assemblies of varying shape and size, suitable for disposing within a variety of different fluid containers, are created. In one embodiment, the base module is made from an expanded mesh which is rolled in a novel cylindrical configuration according to a novel methodology. In another embodiment, the base module may be combined with other base modules to form an assembly.

A flame mitigation device (FMD) for use within a portable fuel container includes a generally cylindrical body having an interior sidewall and exterior sidewall. An annular rim is configured at an upper end of the body and a bottom wall is further configured at a lower end of the body. The FMD includes one or more indented fuel flow members extending from the interior of the annual rim for decreasing cyclonic effect of fuel flowing into the body and a plurality of stepped ribs configured on the interior sidewall of the body for centering diesel and gasoline fuel pump nozzles when inserted into the body. A reverse domed shaped bottom help to disperse fuel though a plurality of substantially rectangular shaped holes through the side wall and bottom wall.

Various techniques are provided for an energy absorbing fluid bladder. In one example, the fluid bladder includes a bladder body and a perforated baffle structure. The perforated baffle structure can be disposed within the bladder body and configured to mitigate a pulse of fluid (e.g., fuel) moving within the bladder body before the pulse reaches the bladder body. Related methods are also disclosed.
