EVALUATION OF EFFECTS RESULTING FROM INTENTIONAL OR ACCIDENTAL DETONATION OF EXPLOSIVE DEVICES BEFORE AND POST-EVENT
Abstract
Unwanted effects of detonation of explosive materials (explosions) can occur due to deliberate actions (terrorist attack) or accidental. Modelling the effects of the explosion on the environment and the urban neighboring, occupies an important place in global and national research programs for the modernization of techniques for the safe use of explosives, in order to combat and operatively counter accidental explosions or those based on their use for terrorist purposes. The current trends are on the way to approximate as accurately as possible the manifestation of the effects of the explosion in order to anticipate the final results. This approach cannot be developed without addressing the interaction between explosive devices and the adjacent environment on which the effects caused by their detonation are manifested. These studies are performed on theoretical models that allow the approximation of the real conditions, encountered in practice. Subsequently, with the help of the experimentally obtained results, a large number of solutions for the design of security measures involving the intentional or accidental detonation of explosive devices can be verified. The paper presents a practical way to analyze, test, evaluate before and after the event of representative explosion scenarios, with the help of a specialized software application of American origin. Based on the results of grapho-analytical quantification of the specific associated hazards, an assessment is made of the risk situations generated by the detonation of explosive devices of different types and constructions, in order to determine the level of safety or the corresponding degree of insecurity.
