Abstract: A containment vessel for liquid waste including an inlet for introducing liquid waste into the container, and a coating of a gelling substance adhered to the interior surface of the vessel by an adhesive which dissolves when contacted by the liquid waste to release the gelling substance and thereby transform the liquid waste into a non-pourable gel. A tip indicator indicates if the vessel has been tipped after the vessel has been put into service. Also, an in-service indicator indicates that the vessel has been put into service and that the tip indicator has been released. A full indicator indicates when the contents of the vessel reaches a predetermined level of fullness. A vent for venting the interior of the vessel during filling of the vessel is automatically closed off when the vessel has reached such predetermined level of fullness. The inlet to the vessel may be connected to a drain opening of an embalming table by means of an expandable tube which allows for adjustment of the height of the table.
