Abstract
A remote spill containment apparatus that includes a horizontally oriented cylindrical housing, preferably formed of a single piece of rolled sheet steel closed front and back by welded spun plates. The upper, forward cylinder quadrant is cut away to form the access opening which is closed by an L-shaped lid hinged to rotate for storage beneath the housing to permit safe access to the housing interior. A single, infinitely adjustable post supports the rear of the housing for free access to the spill drain valve assembly located at the cylinder bottom. The round parts prevent snow and rain accumulation above the access opening and reduce manufacturing costs, weight and space of the unit. Spill liquid within the housing flows toward the bottom centerline lowest zone for selective removal through the spill valve assembly.
