An appliance containment device may include a shell having a shell floor and a shell wall, and a cover having a cover floor and a cover wall. The cover wall and shell wall may be coupled together. A first mat may be coupled to the cover floor. A container cavity for receiving portions of an appliance may be formed above the cover floor and shell floor, and the cavity may be bounded horizontally by the shell wall and cover wall. Lower portions of an appliance may be positioned in the container cavity. Optionally, the device may include an encasement which may be positioned around the upper portions of the appliance with lower portions of the encasement extending into the container cavity, thereby allowing the device to encase the appliance within the shell, cover, and encasement.
