RISK ASSESSMENT MODELING AND VISUALIZATION

The MEMbrain toolkit provides methodological and computer-based suppor t for personnel responsible for the management of emergencies. It link s geographical information system (GIS) technology to environmental mo nitoring, emergency preparedness planning, accident simulation, and cr isis time communication. Tools were developed for municipal fire and r escue operations in the Finnish sub-project of MEMbrain. The users wer e given easy access to basic registers of population, building, teneme nt and property information, and state-of-the-art tools for risk asses sment were integrated into the GIS framework. Chemical accidents can o ccur in varying conditions and evolve in numerous ways. The quantitati ve models incorporated into the RISKWIT consequence modelling software package cover the variations well, and make the reliable quantitative assessment of accident consequences possible.
