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.
