A form-coded collar assembly that is configured to be attached around a filling pipe extending into an underground fuel storage tank and comprises a radial lip defining an opening at its open end, and a system having a plurality of such form-coded collar assemblies. The collar assembly has a base plate with a hollow center comprising a greater footprint than the filling pipe; a form-coded collar that corresponds to a substance contained within the underground storage tank; and a sidewall extending between a user-facing surfaces of said base plate and said form-coded collar.

A rapid deployment containment tank includes an inflatable container and a self-contained compressed gas source. The container defines a liquid chamber and an open top through which a liquid passes into the liquid chamber. The container is shiftable between a deflated configuration and an inflated configuration. The container includes a flexible base wall and a flexible sidewall cooperating to define the liquid chamber. The sidewall projects from the base wall along an interface and includes an air chamber. The air chamber includes a plurality of tubular columns spaced apart along the interface. The compressed gas source is coupled to the container and is fluidly connected to the air chamber to supply a compressed gas for inflating the container. The tubular columns are fillable with the compressed gas to cause the sidewall to lift upwardly from the base wall, as the container shifts from the deflated configuration to the inflated configuration.

A bladder for retaining material to be stored within a bladder tank. The bladder comprises a flexible enclosure comprising a floor portion connected to one or more wall portions, and a leak retention enclosure having upper and lower edges sealed to the flexible enclosure to create a sealed chamber between the flexible enclosure and the leak retention enclosure. Leakage of material from within the flexible enclosure adjacent to the sealed chamber is received within the sealed chamber and retained by the leak retention enclosure.

A roll-off tub style container which is leak-proof to prevent liquids in the container from draining onto the ground or roadways. In one embodiment of the invention, the floor of the container has an upwardly and rearwardly extending inclined portion at the rearward end thereof to prevent liquid in the container from coming into contact with the tail gate of the container. In another embodiment of the invention, the rearward end of the container is elevated during transport to prevent liquid in the container from coming into contact with the tail gate. In yet another embodiment of the container, the floor of the container is inclined upwardly and rearwardly from the forward end thereof to the rearward end thereof. A liquid collection tank may be positioned beneath the floor of the container which has an inlet in fluid communication with the interior of the container and a discharge outlet provided thereon to permit liquid in the tank to be selectively drained therefrom.

A device for securely storing liquid hazardous material. The device includes a housing for receiving a storage container for the liquid hazardous material. The housing has a rear protective wall which is designed to protect a rear side of the storage container, a first and a second side protective wall which are designed to protect two side walls of the storage container, and a front protective wall which is designed to protect a front side of the storage container, and a fluid-permeable platform which is designed as a supporting surface for the storage container within the device, and a collection region which is fluidically connected to an inner region of the housing. The front protective wall is designed to be arranged on the storage container in order, when the storage container is received in the device, to form the housing.

A containment tray for holding, transporting and/or storage of objects, such as, preferably, liquid-filled or, more preferably, oil-filled objects. More particularly, the invention relates to a containment tray capable of holding, transporting and/or storing liquid-filled industrial objects and preventing leaking of both hazardous and non-hazardous materials from such objects when in the containment tray into the outside environment.
