ABSTRACT:
A waste disposer safety device comprises a first member positionable adjacent access to a waste disposer and a second member with access restriction, the first and second members being rotatable with respect with one another to achieve an "off" position and an "on" position whereby in the "on" position, in which operation of the waste disposer is enabled, there is no hazardous access to the grinding chamber thereof, and an "off" position in which the second member can be removed for access to the grinding chamber whereby in that position the grinder motor is inoperable. Switches for accomplishing the on/off condition of the first member and second member and of the waste disposer may be electromechanical or magnetic, among other types of switches.
