Abstract
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.
Claims7
A method of erecting a portable containment berm having a floor and an upright sidewall secured to the floor to present a containment zone, and support structure for the sidewall including a plurality of deployable support assemblies secured to the sidewall and pivotal about respective upright axes during said deployment thereof, there being an elongated, common strap presenting a longitudinal axis and extending along the length of said sidewall and secured to a plurality of said support assemblies, said method comprising the step of simultaneously pivoting said plurality of said support assemblies about said respective upright axes to cause the support assemblies to assume a deployed position extending from the sidewall, said simultaneous pivoting step comprising the step of pulling said elongated common strap to cause the strap to shift along the longitudinal axis thereof and relative to said berm floor and sidewall so that said plurality of support assemblies simultaneously assume said deployed position.
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 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, each of said support assemblies 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 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;
- and
- an elongated, common strap presenting a longitudinal axis and extending along the length of a portion of said sidewall and secured to a plurality of said support assemblies, said strap being shiftable along said longitudinal axis and relative to said floor and sidewall, and operable to substantially simultaneously pivot the connected support assemblies from the retracted to the deployed positions thereof, in order to facilitate erection of said berm.
