Containment berms (40) for the collection of hazardous materials are provided which include a floor (42) with an upstanding, continuous, foldable sidewall (44) to define and internal zone (46) for receiving and holding hazardous materials. The sidewall (44) may be supported by means of external support structure (48) and/or internal support structure (50). The support structures (48, 50) each include a plurality of support leg assemblies (52, 52a) which are secured to sidewall (44) and are pivotal about respective upright axes (66, 66a, 150) and are pivotal from retracted positions close to the sidewall (44) to deployed positions extending from the sidewall (44) and substantially perpendicular thereto.

1. A containment berm, comprising: a generally horizontally extending floor;an upright, foldable sidewall connected to said floor to cooperatively present an interior containment zone for holding hazardous material;support structure operably coupled with said sidewall and including a plurality of support leg assemblies secured to said sidewall and being pivotal about respective upright axes proximal to the sidewall, each of said upright axes extending upwardly relative to said floor, said support leg assemblies each having an elongated lower margin and pivotal from a retracted position close to said sidewall to a deployed position extending from said sidewall, said support leg assemblies in the deployed position thereof operable to prevent collapse of said sidewall under the influence of the weight of said hazardous material within the containment zone; andretaining structure associated with each of said leg assemblies and operable to maintain the leg assemblies in said deployed position,each retaining structure comprising an elongated first strap secured to said floor or sidewall at a position laterally spaced from the upright axis of the associated support structure, and to said support leg assembly at a point spaced from said sidewall when the support leg assembly is deployed, such that the longitudinal axis of said first strap is obliquely oriented relative to the elongated lower margin of the associated leg assembly when deployed. 2. The containment berm of claim 1, said support leg assemblies each including a rigid member having an upright section proximal to said sidewall and a lower section extending from said sidewall in said deployed position. 3. The containment berm of claim 2, said rigid member formed of metal or synthetic resin and being generally L-shaped. 4. The containment berm of claim 2, said rigid member being encased within a non-load-bearing, flexible sheath. 5. The containment berm of claim 1, each of said support leg assemblies including a flexible strip of material secured to said sidewall, said flexible strips defining said upright axes and permitting said pivoting of said support leg assemblies. 6. The containment berm of claim 1, said first strap being flexible and having a pair of spaced apart weights oriented such that when said support leg assembly is pivoted about the adjacent upright axis, the first strap moves under the influence of gravity to assist in the deployment of the support leg assembly. 7. The containment berm of claim 6, including a second strap in overlying relationship to said first strap to prevent inadvertent pivoting movement of the support leg assembly from said deployed position. 8. The containment berm of claim 1, including a retaining member pivotally coupled to said support leg assembly in overlying relationship to said first strap, said retaining member operable to prevent inadvertent pivoting movement of the support leg assembly from said deployed position. 9. The containment berm of claim 1, said retaining structure further comprising first and second retaining elements each proximal to said support leg assembly and being pivotal about respective upright axes, said retaining elements extending from said sidewall and in close adjacency with the opposed sides of the support leg assembly when the support leg assembly is in said deployed position, said first strap secured to said first retaining element. 10. The containment berm of claim 9, there being a second retaining strap, said second strap secured to said floor or sidewall and said second retaining element. 11. The containment berm of claim 1, said support leg assemblies secured to said sidewall by means of rail and pin assemblies to permit said pivoting movement of the support leg assemblies. 12. The containment berm of claim 1, including a pull strap operably coupled with at least certain of said support leg assemblies in order to permit simultaneous pivoting movement of the support leg assemblies from said retracted position to said deployed position by pulling on the pull strap. 13. The containment berm of claim 12, said pull strap being secured to said support leg assemblies at the ends thereof remote from said sidewall when said support leg assemblies are in said deployed position. 14. The containment berm of claim 1, said floor and sidewall formed of flexible synthetic resin material. 15. The containment berm of claim 1, said zone being liquid tight to prevent escape of liquid hazardous material from the zone. 16. The containment berm of claim 1, each retaining structure further including a substantially triangular retaining element operably coupled to said support leg and overlying said first strap in said deployed position.
