This document summarizes the PRACTICE project which aims to develop an integrated toolbox to improve coordination and response to CBRN terrorism events in Europe. The toolbox will integrate capabilities across different response organizations. It will identify key event parameters and operational functions to map how first responders detect and handle events. The toolbox concept and tools will be developed through workshops with end users and validated through field testing and training kits. The goal is to enable a faster, more precise response to CBRN events through improved information sharing and optimized resource use.
