Updating explosive materials together with developing technologies and making many areas available increased the consumption of explosives. Incorrect and unconscious use of explosives in mines and quarries where explosive rock excavations are made, in industrial structures, in all kinds of construction activities may cause structural damage in underground and aboveground structures, and psychological problems in living beings. In order to minimize the problems such as vibration, air shock and dust caused by blasting applications, it is necessary to carry out blasting performance analyzes and apply appropriate blasting patterns to the field structure. While the appropriateness of these analyzes and designs is determined, damage criterion tables and graphs are used that are generated by many countries. Until 2005, USA (USBM, OSMRE) evaluation tables were utilized in Turkey and after this year, "Turkish Damage Assessment Criteria", which is similar to American norms, took place in the "Environmental Hazard Assessment and Management Regulation" of the Ministry of Environment and Forestry. Especially, whether the vibration effects caused by detonation damaging to surrounding settlements and constructions is determined by accepting the boundary curve in the Turkish damage assessment chart. In some cases, however, even if the vibration values obtained from the blasting applications remain below this curve, they can cause some damage to the constructions. In this study, damage potentials of blasting applications made with nonel ignition system are evaluated according to Turkish and German DIN 4150 damage assessment criteria. As a result, it has been understood that all vibration values obtained from blasting applications are below the Turkish damage assessment curve and there is no potential for any damage. However, when considered according to the German DIN 4150 norm, a few particle velocities appeared to be at the bottom and potentially damaging to the curve showing the highest permissible limit for unstable constructions such as mudbrick, old worn historical artifacts.
