SOCRATES: a computerized toolkit for quantification of the risk from accidental releases of toxic and/or flammable substances
A computerised toolkit for quantification of the risk from accident releases of toxic and/or flammable substances is presented. Methodological and procedural steps for quantifying the consequences and the associated risk to health is presented, along with their implementation in a user-friendly computer package. The methodology and the associated toolkit have the capability of integrated risk analysis, that is calculation of two risk indices: individual risk and group risk. The code is capable of handling multiple accident scenarios, complex terrain dispersion and uncertainty quantification (including parameter and model uncertainty), and is characterised by a user-friendly graphic user interface. An application of the methodology and the code in a case study is also provided.
