ABSTRACT:
A safety device for open receptacles adapted for use with flammable solvents and the like. The safety device comprises a unitary piece adapted to be received within the drain opening of a sink or other receptacle in which parts and mechanical components are temporarily received for cleaning by passage of solvent thereover. The device includes a locating flange, and a wall which subdivides the receptacle drain opening into an ordinary flow path and a second opening. The wall also defines an alternate drain flow path between other portions of the receptacle interior and the drain opening. The alternate flow path to the secondary drain is preferably defined by a contoured wall which cooperates with the interior surfaces of the receptacle to define a drain path for solvent which can flow through the principal drain path. This wall contains a large number of openings so that accidental or even intentional blockage of the drain path cannot be readily accomplished. Accordingly, the possibility of unsafe accumulation of a solvent in the receptacle is greatly reduced and the safety hazard occasioned thereby is eliminated or minimized.
