ABSTRACT:
A lined metal box for the containment and possible transportation of solid state electronic components is provided with a lid having a key-actuated securing latch therefor. In order to assure that no high voltage can be applied to the case, and more particularly its contents during the transfer thereof, the key for the metal case is provided with a grounding so adapted to ensure grounding of the case before the lid can be released and the contents therein made accessible. The box lining comprises an electrically conductive foam lining, to ensure that no cumulative electrostatic charge can build up, as all such charges leak to the box structure. At the time of unloading the box, the box is grounded and all electrostatic potentials are effectively reduced to the ground value.
