Side walls of the tray are supported by removable bolster segments formed of resilient open cell foam members enclosed within sleeves. The bolster segments are wrapped within a flap of material extending from under the side wall of the tray and around the bolster segments to secure them to the side walls. The outer edge or end of the flap is secured to the side wall. The bolstered side walls may be repeatedly driven across by industrial vehicles without harming the bolster or side wall. The modular bolster segments may be removed and easily stacked, and the tray folded and rolled into a compact modular form, for transport, storage, and reuse of the portable containment tray. ## Claims ### Claim 1 A portable, modular containment tray system comprising: a tray formed of a chemically resistant fabric and having upward-extending side walls; a plurality of deformable bolster segments positioned adjacent said side walls; and a plurality of flaps extending outward from the perimeter of said tray and disposed at intervals around said perimeter of said tray, said flaps enclosing said deformable bolster segments to secure said bolster segment with said side walls. ### Claim 2 (depends on 1) The tray system of claim 1, comprising: for each said flap at least one fastening mechanism attached thereto for securing said flap to said side wall. ### Claim 3 (depends on 2) The tray system of claim 2, wherein said fastening mechanism is selected from the group consisting of a hook and loop fastener, spring clips, laces, and cords. ### Claim 4 (depends on 1) The tray system of claim 1, comprising: one or more pull handles secured to said side walls. ### Claim 5 (depends on 4) The tray system of claim 4, comprising: said pull handles spaced at intervals along said side walls if more than one said pull handle is attached thereto. ### Claim 6 (depends on 1) The tray system of claim 1, wherein said deformable bolster segment comprises: a resilient core formed from an open cell synthetic foam material cut to a length. ### Claim 7 (depends on 6) The tray system of claim 6, wherein said deformable bolster segment comprises: a member formed as a solid core of open cell synthetic foam material cut to length and a four-sided cross section having at least one right angle. ### Claim 8 (depends on 1) The tray system of claim 1, wherein a said deformable bolster segment comprises: a member formed of a resilient foam material cut to length and having a cross sectional shape including at least one right angle corner. ### Claim 9 (depends on 6) The tray system of claim 6, wherein said deformable bolster segment comprises: a sleeve conformably enclosing said resilient core, said sleeve formed of a chemically resistant fabric. ### Claim 10 (depends on 9) The tray system of claim 9, wherein said sleeve includes at least one air vent at each end of said bolster segment. ### Claim 11 (depends on 10) The tray system of claim 10, wherein said air vent is disposed proximate an upward side of said bolster segment when attached to a said side wall of said tray. ### Claim 12 (depends on 1) The tray system of claim 1, wherein: said flaps are formed to have a width extending along substantially the length of each said side wall. ### Claim 13 (depends on 1) The tray system of claim 1, wherein: said flaps are formed as narrow flaps spaced at intervals along substantially the length of each said side wall. ### Claim 14 A method for installing a portable containment tray system, comprising the steps of: placing, on a site, a containment tray having upward-extending side walls disposed around the perimeter thereof and a first fastening mechanism with said side walls, said containment tray further including flaps extending outward from the perimeter thereof; positioning a plurality of deformable bolster segments adjacent said side walls; surrounding said bolster segments with said flaps; and securing said flaps around said bolster segments using a second fastening mechanism with said flaps. ### Claim 15 (depends on 14) The method of claim 14, further comprising the step of: providing a first fastening mechanism or a second fastening mechanism selected from the group consisting of a hook and loop fastener, spring clips, laces, and cords. ### Claim 16 (depends on 15) The method of claim 15, wherein the step of providing comprises the steps of: attaching said first fastening mechanism to selected locations along the perimeter of said containment tray; and attaching said second fastening mechanism to a corresponding selected portion of said flaps. ### Claim 17 (depends on 14) The method of claim 14, wherein said step of positioning a plurality of deformable bolster segments comprises the step of: forming each said bolster segment from a resilient foam material cut to a predetermined length. ### Claim 18 (depends on 14) The method of claim 14, wherein the step of positioning comprises the step of: forming each said bolster segment from an open cell synthetic foam material cut to said predetermined length. ### Claim 19 (depends on 14) The method of claim 14, wherein the step of positioning comprises the step of: forming said bolster segment to a cross section having at least one right angle corner along said predetermined length. ### Claim 20 (depends on 14) The method of claim 14, wherein the step of positioning a plurality of deformable bolster segments comprises the step of: enclosing said deformable bolster segments in a sleeve formed from a chemically resistant fabric. ### Claim 21 (depends on 20) The method of claim 20, wherein the step of enclosing comprises the step of: including at least one air vent at each end of and in an upward side of said sleeve enclosing a said deformable bolster segment. ### Claim 22 (depends on 14) The method of claim 14, further comprising the step of: forming said flaps to extend along substantially the length of each said side wall. ### Claim 23 (depends on 14) The method of claim 14, further comprising the step of: forming said flaps as separate narrow flaps disposed at intervals along substantially the length of said side wall. ### Claim 24 (depends on 14) The method of claim 14, further comprising the step of: forming said containment tray and said upward-extending side walls of a chemically resistant fabric. ### Claim 25 (depends on 14) The method of claim 14, further comprising the step of: attaching one or more pull handles to said side walls; wherein if more than one said pull handle is attached, attaching said pull handles at spaced intervals along said side walls.
