An overpack salvage drum including a drum body for holding a package to be overpacked, a lid adapted to be rotatably threaded onto the drum body to seal the package held in the drum body therein, and a clip adapted to be operatively associated with the lid before the lid is rotatably threaded onto the drum body. The clip is adapted to break in preference to the lid and the drum body in the event that the initial integrity of the seal between the lid and the drum body is compromised.
