A containment berm comprising a containment material that is configured to provide at least a floor and four walls of the berm, a plurality of brackets positioned on the floor and adjacent to the inside surface of the four walls, and a top rail. Each bracket comprises a vertical member, connecting member, and horizontal member. A first end of the vertical member is pivotally connected to a first end of the horizontal member at a first pivot point. A first end of the connecting member is pivotally connected to the horizontal member at a second pivot point between the first and second ends of the horizontal member. The top rail extends around a top perimeter of the four walls of the berm. Each bracket comprises a clamp portion that is situated on a second end of the vertical member and that clamps onto the top rail.

1. A containment berm comprising: (a) a containment material that is durable, flexible and chemically resistant, the containment material configured to provide at least a floor and four walls of the berm, wherein each wall has an inside surface;(b) a plurality of brackets positioned on the floor and adjacent to the inside surface of each of the four walls, each bracket comprising a vertical member, a connecting member, and a horizontal member, wherein a first end of the vertical member is pivotally connected to a first end of the horizontal member at a first pivot point, wherein a first end of the connecting member is pivotally connected to the horizontal member at a second pivot point between the first end of the horizontal member and a second end of the horizontal member; and(c) a top rail, wherein the top rail extends around a top perimeter of the four walls of the berm;wherein each bracket comprises a clamp portion that is situated on a second end of the vertical member, the containment material forms a hem along the top perimeter of the berm, the top rail extends through the hem, and the clamp portion clamps onto the top rail at a cut-out in the hem;wherein the clamp portion comprises; a stationary bracket that is concave in shape and pivotally connected at a bottom end of the stationary bracket to a pivoting bracket that is concave in shape and that has a recess;a bolt with a pivoting end that is pivotally connected to a top end of the stationary bracket; anda wing nut;wherein to close the clamp portion, a top end of the pivoting bracket is pivoted toward the top end of the stationary bracket, the bolt is inserted into the recess in the pivoting bracket, and the wing nut is tightened on the bolt; andwherein both the stationary bracket and the pivoting bracket are concave in shape so that the top rail fits inside of the clamp portion when it is in a closed position. 2. The containment berm of claim 1, wherein each bracket comprises a bottom end, and wherein the bottom end of each bracket fits into a pocket in the floor of the berm. 3. The containment berm of claim 1, wherein a second end of the connecting member comprises a hole that extends laterally through the connecting member, wherein the vertical member comprises at least two holes that extend laterally through the vertical member between the first and second ends of the vertical member, and wherein a pin extends through the hole in the connecting member and one of the at least two holes in the vertical member. 4. The containment berm of claim 1, wherein the clamp portion is situated directly above the first pivot point. 5. The containment berm of claim 1, further comprising a geotextile pad situated between the bracket and the containment material proximate to the first pivot point. 6. The containment berm of claim 1, further comprising at least one corner brace, wherein the at least one corner brace comprises two clamp portions and a cross-bar, wherein the clamp portions clamp onto the top rails of adjacent walls of the berm, and wherein the cross-bar extends between the two clamp portions. 7. The containment berm of claim 1, wherein the vertical member comprises a channel extending from the first end of the vertical member to the second end of the vertical member, and wherein the connecting member fits into the channel in the vertical member when the bracket is fully collapsed.
