DESCRIPTION:
BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This is a national phase application corresponding to PCT/CH85/00064 filed Apr. 24, 1985 and based upon a Swiss national application No. 2059/84--0 filed Apr. 28, 1984 under the International Convention.
FIELD OF THE INVENTION
The invention relates to an arrangement for the protection of buildings from terrorist attacks, in particular attacks using explosives, with a protective wall placed before the building.
BACKGROUND OF THE INVENTION
With certain buildings, for example power stations, radio and television stations, pylons for high-voltage lines, military installations or the like, there exists today an increasing danger of acts of terror for political reasons. Hitherto known protective devices for such installations have included relatively high barbed-wire fences or concrete walls, erected at relatively great distances of, for example, about 100 m from the outer wall of the endangered building or construction. However, these obstacles can be overcome relatively quickly by terrorists with special tools, especially by blowing them up, so that the time for alerting the police and their arrival at the scene of the crime is too short to prevent a local destruction of the outer wall of the building, the forced entry of the terrorists into the building, their actual destructive work in the interior of the building and their escape. In addition, there is often no possibility of erecting a protective wall at a considerable distance from the facade wall of the building owing to the lack of space at the locality. Sufficient security for the prevention of logistically carefully prepared acts of terror is thus in most cases not provided for at all.
OBJECT OF THE INVENTION
The object of the invention is to overcome the previously-mentioned disadvantages of the known protective devices, and to provide a protective arrangement which can be placed before the outer wall of the building and cannot be overcome without difficulty and hence relatively great expenditure of time by the terrorists, so that the time required to alert the police and for their timely appearance at the scene of the crime is maximized and prevention of the actual terror attack aimed at the building can be ensured.
SUMMARY OF THE INVENTION
Accordingly, the invention causes a delay in a terror attack by the generation of smoke and fumes. To this end, the protective wall comprises a combustible mass, in which ignition devices are embedded which are capable of being set off by a bomb explosion through a deformation of the protective wall, and, for setting off and, therewith, setting on fire the combustible mass, contain in each case coordinated amounts of two compounds or elements separated from each other and reacting only by mutual contact exothermically chemically together.
According to the invention acts of terror to overcome the protective wall are usually made practically impossible and even the most highly developed professional attack is thwarted through the intense heat and generation of smoke by means of the combustible mass set ablaze by means of the ignition device.
Penetration is delayed to such an extent that even if the protective wall is at last overcome by the terrorists, the actual terror attack on the intended object can be prevented because the police are alerted in time owing to the relatively great expenditure of time required for the local destruction of the protective wall with sufficient safety to the perpetrators.
Because of the far greater effectiveness of the protective wall according to the invention, the gain of time obtainable by using a relatively great distance between protective wall and facade of the building rather pales into insignificance. Therefore, the protective arrangement according to the invention can also be deployed there where the local space conditions do not make such a great protective distance possible; this is particularly the case when the protective wall is composed of two or more suspended walls which are self-contained and formed of armor plate
