A containment tray for a hazardous material spill pallet for storage of drums containing hazardous material supported on a removable grate, said containment tray comprising
- a bottom wall;
- side walls extending upwardly from the periphery of said bottom wall to form an open-top fluid-receiving chamber;
- a plurality of bottom wall recesses in said bottom wall defining external facing open channels for insertion of pallet lifting means;
- a plurality of support posts, offset from the center of the tray, extending upwardly from said bottom wall, having a grate support surface lying in a grate support plane;
- a ledge, extending outwardly from top edges of said side walls, lying in the grate support plane;
- a peripheral L-shaped flange extending upwardly then inwardly from an outer periphery of said ledge, said L-shaped flange having a substantially vertically oriented and a substantially horizontally oriented face;
- and
- a plurality of flange supports formed by walls extending between said ledge and the horizontally oriented face of said L-shaped flange.
A containment tray according to claim, wherein
- each said flange support is square shaped and partially formed by three walls extending between said ledge and the horizontally oriented face of said L-shaped flange so as to strengthen said horizontally oriented face.
A containment tray for a hazardous material spill pallet for storage of drums containing hazardous material supported on a removable grate, said containment tray comprising
