||The mankind has passed through a significant historical frontier, including technological processes where hazardous substances are the potential threats for the employees, the public, environment and property and therefore it is inevitable to pay increased attention to the occurrence of the industrial accidents and mainly to their prevention. The area of safety of technical and technological systems is very closely connected not only with the reliability of the processes but also with the technical as well as social, legal and other aspects. There exist several systematic approaches, methods and techniques to assess industrial processes and risks linked to these processes on the European Union level and also on the national level of each member state. We can mention some basic systematic approaches – MOSAR, CPQRA, ARAMIS, PRA (PSA) widely used in this area. But according to the analyst's needs they usually miss structured and systematic approach, how to complete the risk assessment in steps and what the content of each of these steps is. The main focus of this paper is to discuss the theoretical aspects of the risk assessment in industrial processes and to show the possible approach of structured and systematic methods with support of logical diagrams to fulfill all tasks concerning the industrial accident assessment. Last but not least it is to present the research activities of the Department of Crisis Management, University of Å½ilina in Å½ilina, Slovakia. Â© 2012 ISCRAM.
