Abstract: A vented suppressive shielding device which may be used in either a permanent building placent or portable device to protect persons or equipment from the effects of an explosive detonation. The shielding is relatively lightweight and comprises a shielding barrier having a frame means, the frame means carrying at least two barrier means in selected position relative to one another. The shielding barrier has oppositely facing surface members, wherein one of these surface members is disposed so as to face an explodable device, with the other surface facing away from the explodable device. Each one of the barrier means is located adjacent to one of the surface members such that one of the barrier means is free to move in the space defined by the frame means and relative to the frame means.
