A carrying case, having a hinged lid, is provided with a handle and locks. Within the interior of the case and hingedly connected to the case is a liner, within which are stored sensitive papers. A thermite charge is within a removable boat in the liner and has igniters electrically connected, through a selectively positionable key operated switch, to a battery and through various switch members so that the igniters are triggered upon the occurrence of and one of various events. One switch member is on the handle and is depressed when carrying the case. Other switch members are closed upon tilting; still other switch members are closed if a knife is passed through the exterior of the container. Still other switches are closed in the event that a knife is inserted to prize open the case or the case is opened without being disarmed. Upon the making of an electrical circuit, the igniters ignite the thermite charge to burn or char the papers, the gases escaping through an opening in the lid of the case.
