The objective of PRACTICE project is to improve the preparedness and resilience of the EU member states and associated countries to an attack from a terrorist group using non conventional weapons such as CBRN (Chemical, Biological, Radiological and/or Nuclear agents) materials. The existing situation is characterized by a fragmented structure as regards technology, procedures, methods and organization on national level as well as EU-level.The project will be based on the development of a new toolbox focusing on 1) identification, organization and establishment of knowledge of critical elements in the event structure thorough studies of a wide selection of scenarios, real incidents and exercises and 2) analysis and identification of gaps in the current response situation and organization and integration of the allocated response capabilities or functions in a toolbox of equipment, procedures and methods and 3) an allocated system or kit for public information, decision-support, first-responder training and exercises.These response capabilities functions are to a great extent universal in character and independent of national organizational structures. The concept and developed system will therefore provide EU and member states with a flexible and integrated system for coordinated response to CBRN terrorist attack, which is easier to adapt to various national organizations and regulations.Particular attention will be given to integration and understanding of human factors and societal aspects in all the parts of the project. The final concept and integrated response system (toolbox) and subsystems will be tested and validated. A whole system demonstrator will be shown and tested in the final phases of the project.
