<p>A portable foldable containment (10) is illustrated for use in containing spilled material and preventing environmental contact. Containment (10) includes a floor (14) and integral side walls (16, 18, 20, 22). Rigid side braces (A), internal braces (B) and second side bracing elements (C) provide support to enable walls (16, 18, 20, 22) to extend upright a considerable distance. Internal braces (B) consist of a first brace segment (26), a second brace segment (28) and a hinge (30). Second side bracing elements (C) consist of a vertical leg (64), a horizontal leg (66), and a resilient hinge (68). These components enable the internal braces (B) and second side bracing elements (C) to be folded allowing walls (16, 18, 20, 22) to be laid horizontally for passage of a vehicle.</p> |
