Abstract
An oil and waste line connection spillage containment apparatus, constructed from non-corrosive and rustproof materials, includes a substantially cylindrical container which has two openings for receiving oil and waste loading and unloading lines therein. The lines are connected within the container.

Any oil and waste spilled from the connection is removed from the container when the lines are disconnected, or alternatively, a removal line with an auxiliary valve affixed thereto, is used to siphon the oil and waste from the container to the loading line. When the unloading line is removed from the opening in the container, a plug having vent holes for releasing gas from the container, is inserted into the opening. The plug and cover are attached to the loading line with an attachment cable. A lock having a hasp is received through passages defined in first and second tabs attached to the container and cover, respectively, for locking the…
