Abstract: A lightweight portable fire resistant containment system has an outer shell and an inner shell that fits inside the outer shell, forming an insulating air gap. A lid closes the outer shell, defining a closed storage space. The outer shell, inner shell and lid are fabricated from high temperature resisting ceramic fibers and are bonded together with an inorganic or charred bond to form a light weight integral component. A stainless steel sheet wrap prevents ingress of flame and hot gas into the bonded ceramic fibers of the outer shell and lid. The inner shell outer surface has a metallic infrared reflecting wrap limiting radiation received from the inner surface of the outer shell. The inner surface of the inner shell has an encased ceramic porous body infiltrated with solidified phase change material, absorbing latent heat of fusion from the interior surface of inner shell and limiting temperature exposure of valuable stored documents and photographs.

Abstract: A method and inhibitor are provided for substantially diminishing the deleterious effects of a bomb blast such as is commonplace with terrorist activities. A generally flexible container filled with a liquid, generally water, is shaped and adapted to substantially cover a bomb to obscure substantially all open spaces from the bomb. The water serves to absorb a large proportion of the energy of the bomb blast and therefore reduces the most dangerous effects of bombs namely that of secondary shrapnel which generally does the most damage and the container and water prevent, to a substantial extent, any primary shrapnel or other debris from being blown out with substantial force. The invention also provides special containers of various different designs as well as a method of manufacturing such containers which are preferably of a resilient nature.
Abstract: On an attack-endangered side of members (1, 6) of a fixed frame and a sash frame mounted swingably therein, respective bombardment-inhibiting profiles (11, 12) with overlapping edge margins (11', 12') are provided. In the overlap region these safety profiles (11, 12) define a gap (13). Since the edge surfaces of the bombardment-inhibiting profiles (11, 12) which define the gap (13) are formed with respective ridges (4, 17) and grooves (15, 16) intermeshed with one another, the gap course is sinusoidal. This offers a high degree of security against shoot-through and break-in in the gap region of the door or of the window.
Abstract: A bulletproof door and door jamb construction includes a door jamb which includes a vertically and horizontally extending opening therein in an area where bullet shrapnel fragments can pass freely therethrough into the hollow interior of the door jamb so that the spent fragments lose their energy and do not enter the protected area behind the door by otherwise passing through the crack or space between the door and door jamb.
