A salvage drum for hazardous materials includes a container and a lid threaded thereon. Projections on the container and lid are engaged by a lever, such as a two-by-four beam. The lever is wrenched to tighten the lid on the container. The projections are symmetrically spaced around the container and lid. The lever can be a bar having a crank with teeth.
