Abstract:
Collapsible fluid containment berms with collapsible sidewalls are disclosed. Support brackets including sidewall support arms may be rotated from lowered positions in which the sidewall is collapsed to raised positions in which the sidewall is generally vertical. The sidewall support arms may be contained in a pocket formed between inner and outer sidewall panels. The support brackets may include bottom legs connected to the rotatable sidewall support arms. The bottom legs may extend generally horizontally outwardly and/or inwardly from the sidewall, and may be contained in sleeves attached to a floor and/or an external skirt of the containment berm. A control strap connected to the sidewall support arms may be used to move the arms between their collapsed positions and their raised positions. A flexible control strap may be pulled to rotate the sidewall support arms around an axis such that the sidewall support arms slide within the sidewall pocket.
Abstract:
Compressible fluid-impermeable berm devices that self-adhere to surfaces such as ground, pavement and floors are disclosed. The compressible containment berm devices include one or more compressible containment wall sections formed from a flexible shell and a compressible filler material. A pre-applied adhesive layer at least partially covers the underside of each compressible containment wall, and is used to adhere and seal the containment wall to the containment surface. Corner joints may be used to connect the compressible containment wall sections together to thereby form the berm devices with a closed perimeter that contains leaks and spills. The compressible fluid-permeable berm devices can be easily removed or repositioned after use leaving little or no adhesive residue.
Abstract:
Protective drain covers, include stiffening members at one end or at opposing ends to increase rigidity in one direction while leaving the other direction flexible. The increased rigidity in the one direction improves the ability to handle and accurately position the protective drain cover for use, while the flexibility in the other direction allows the protective drain cover to be rolled up for storage and future use. The stiffening member(s) can be used as hand-holds to assist in the placement of the heavy protective drain cover and then removal of protective drain cover after use.
Abstract:
Portable collapsible fluid containment devices are disclosed comprising sidewall support braces that rotate from a collapsed generally horizontal position to a raised generally vertical position and lock into place. The sidewall braces may be attached to at least one sidewall of the containment device, and when raised support the sidewall in a fluid containment configuration. The sidewall braces comprise a base support leg, a sidewall support arm rotatably mounted on the support leg, and a locking tab for holding the sidewall support arm in the generally vertical position.

Abstract:
Multiple-can aerosol puncturing systems that are capable of puncturing multiple aerosol cans in a single operation are disclosed. A can holder with multiple chambers and a movable lid are used to contain the aerosol cans. A vertically movable actuation plate with multiple hollow puncturing pins is raised toward the can holder to puncture the lids of the aerosol cans. The heights of the puncturing pins may be staggered in order to puncture the lids sequentially during the same draining operation.
Abstract:
Absorbent containment mats are disclosed. The mats include an upper absorbent layer, a lower liquid impermeable barrier layer, and a peripheral containment edge. The peripheral containment edge may have a lower profile than the absorbent layer. A pressure sensitive adhesive may be applied to the underside of the barrier layer. A durable porous layer may be provided over the absorbent layer.
Abstract:
Shapable protective covers for vertical drains and other holes to prevent spills and other liquids from flowing therein are disclosed. The shapable protective covers include a backing layer with a malleable shapable core and a pliable, tacky sealing layer. The pliable, tacky sealing layer may be secured to the other layers by a bonding layer adhered to or partially embedded in at least one of the layers. The shapable protective covers may be positioned over a vertical drain such that an exposed surface of a pliable, tacky sealing layer contacts a portion of the surface surrounding the vertical drain, thereby preventing liquids from passing through the drain.

Abstract:
Multiple-tube stormwater filter socks may be used to mitigate stormwater environmental runoff of sediment, hydrocarbons and heavy metals. The stormwater filter socks comprise at least two tubes that are spaced apart by a separator web, and are filled with different types of absorbent media. The stormwater filter socks may be placed around the top grate of a storm drain chamber, and around other environmental runoff sources such as trash bins, roof downspouts and outdoor material stockpiles. The multiple-tube stormwater filter socks may be used to mitigate drips and spills of hydrocarbons such as motor oils, and may be used to contain zinc, copper, lead, chromium, cadmium and other heavy metals.
