Abstract

The figure illustrates a chemically resistant, liquid tight containment vessel 9 that is attached to the exterior wall of a chemical loading dock 10. The vessel size is narrow enough to fit between the back wheel 11 of a semi-trailer 12 and the dock 10. The vessel is opened by the truck's ICC bar 13 striking an actuating device 14 which pushes down the hinged lid 15. Counterweights cause the lid to close when the truck is not in position. The top lid is hinged from the inside, and sloped, seals exist on three sides; these features prevent rainwater intrusion when the system is not in use. A liquid indicator exists within the vessel to actuate an alarm for the dock operators in the event of a chemical spill. A limit switch is attached to the lid to notify the operator that the door has opened when a truck arrives.

Truck Dock Chemical Containment System

The figure illustrates a chemically resistant, liquid tight containment vessel 9 that is attached to the exterior wall of a chemical loading dock 10. The vessel size is narrow enough to fit between the back wheel 11 of a semi-trailer 12 and the dock 10. The vessel is opened by the truck's ICC bar 13 striking an actuating device 14 which pushes down the hinged lid 15. Counterweights cause the lid to close when the truck is not in position. The top lid is hinged from the inside, and sloped, seals exist on three sides; these features prevent rainwater intrusion when the system is not in use. A liquid indicator exists within the vessel to actuate an alarm for the dock operators in the event of a chemical spill. A limit switch is attached to the lid to notify the operator that the door has opened when a truck arrives. This switch is also capable of being interlocked to the dock door or the leveler so that chem ical unloading could not occur without the vessel being open.

Some features of the vessel can be substituted or deleted and still provide an effective containment system. Any material that is strong enough and liquid tight can be used. The ICC bar actuated device for opening the vessel is really only effective in the United States installations. In lieu of this device the vessel could be manually opened or have a motorized opener.

The advantages include: No underground double-walled piping, tanks or containment vaults are r...
