ABSTRACT:
A method of selectively closing off a loading dock opening defined by a loading dock pit recessed within a floor of a building and a doorway into the building, the method comprising: (a) repositioning a pit seal panel having a substantially incompressible height and width to a barrier position where the pit seal panel closes off a rectangular area substantially spanning an entire vertical dimension and an entire widthwise dimension of the loading dock pit; and (b) lowering an overhead door to concurrently contact the pit seal panel and the floor of the building to close off the loading dock opening.
