An article storage device is provided for holding a plurality of standardized containers. The standardized containers extend between a bottom surface extending generally horizontally and a top surface spaced from and generally parallel to the bottom surface. The standardized containers further include an opening side perpendicular to the top and bottom surfaces and a door flange extending along the opening side and beyond the top surface. The standardized containers further include a lifting flange attached to the top surface for receiving a lifting tool. The standardized containers are disposed in the storage rack with their respective opening sides facing away from an access space for allowing a retrieval transport apparatus to move in a substantially horizontal plane between the access space to engage the lifting flange without being obstructed by the door flange.
