Work package 4 of the Saphedra project, “Building a European Platform for evaluation of consequence models”, is aimed at an identification of existing experimental campaigns for the validation of the tools for consequence modelling identified in WP1 of this project. On the basis of the classification into various phenomena proposed in WP 1, the identified experimental campaigns will be described in the following. This report contains a description of experimental campaigns associated to typical phenomena resulting from the release of hazardous materials. The results of the analysis of these experimental campaigns is then summarised in form of a spreadsheet. This spreadsheet is to be seen as an integral part of the report of WP4.

This report forms the output of WP3 of the SAPHEDRA project, which is to review existing model evaluation protocols and to make recommendations for the structure and content of a new evaluation method that can be broadly applied to models used in risk assessment studies for hazardous materials.

The report identifies a shortlist of the accident scenarios associated to new and emerging risks related to industrial technologies. The document also describes the results of the gap analysis between emerging risk scenarios and existing consequence models. A set of test cases for the comparison of the available models is also identified. The results of the gap analysis between emerging risk scenarios and existing consequence models are also reported. A set of test cases for the comparison of the available models is also identified.

An accidental release of hazardous chemicals will typically result in a number of potential physical effects. Depending on the properties and the storage conditions of the material, several typical phenomena may occur: fire, explosions or toxic exposures. In order to evaluate the potential danger, so-called “consequence assessment” models can be applied to predict the physical behaviour, or the phenomena occurring upon release of a hazardous substance. Work package 1 of the Saphedra project, “Building a European Platform for evaluation of consequence models”, is aimed at an identification of existing tools for consequence modelling. In order to be able to identify and describe these tools, a classification into various phenomena is proposed. This document contains a description of typical phenomena, associated with the release of hazardous materials. This classification is then applied to collect and describe various tools in the form of a spreadsheet. This spreadsheet is to be seen as an integral part of the report of WP1.

This report published by the UK HSE forms the output of work package  three of the SAPHEDRA project, which was to review existing model  evaluation protocols and to make recommendations for the structure and  content of a new evaluation method that can be broadly applied to models  used in risk assessment studies for hazardous materials.
