A jettison device isolates an object, particularly a potentially hazardous object on a ship, platform or similar object. The jettison device includes a housing with an opening configured to face towards an outside region, and a container configured to hold one or more of the objects. The jettison device further includes a container lock and a container jettison. A ship, platform or other vessel includes at least one of the jettison devices above and at least one jettison device arranged in or near a hull surface with the opening facing a region outside the hull surface.
