Abstract
The scientific article highlights the synthesis of the research results to assess the effect of explosive pressure on the detonation of various quantities of explosives in order to ensure a predictable level of societal security. The results of the experimental researches highlighted in the scientific papers were obtained following the tests with explosive materials performed on different specially configured experimental assemblies in order to analyze the propagation of the pressure wave on a mobile platform with specially configured pressure and gas sensors as well as on the explosion pressure measuring sensors within two modern Kistler systems. The visualization of air pressure waves for the experiments performed with these working montages was done by using a high-speed camera based on the BOS effect applied on fast video filming with adequate quality characteristics on the number of frames per second and the resolution obtained.
Highlights
These hazards have a low probability of occurrence and are either not considered in structural design for economic reasons or addressed indirectly through passive protective measures rather than by structural calculations (NISTIR, 2007)
Note that Ammonium Nitrate has a long history in deliberate attacks

Summary
These hazards have a low probability of occurrence (the order of 10-7 to 10-6 per year) and are either not considered in structural design for economic reasons or addressed indirectly through passive protective measures rather than by structural calculations (NISTIR, 2007). Eurocodes) offer limited information and explicit provisions for designing buildings or other infrastructure assets to resist such events. Engineers need more training and information so that they can provide designs that effectively enhance a building’s response to such loading events. Blasts (explosions) may occur due to deliberate (intentional) or accidental actions. Deliberate explosives come in two general categories, i.e., military and civilian (or commercial). These are referred to as high explosives. Commercial explosives include such products as dynamite, TNT (trinitrotoluene) and Ammonium Nitrate (AN) among others. Note that Ammonium Nitrate has a long history in deliberate attacks. Accidental explosions may be produced by explosives but more often are caused by natural gas
