Description
Phast Risk 6.6 contains an extension for modelling the risks from explosions. This approach takes account of the effects of congestion and confinement when calculating overpressure and impulse results and allows selection of either the Multi Energy or Baker Strehlow Tang explosion methodologies. This course, which complements SA-12, goes into more technical details about the explosion and vulnerability modelling available in the Phast Risk explosion extension. It describes the theory behind the Multi Energy and Baker Strehlow Tang models as implemented in Phast Risk and provides background information on some of the guidance in the literature on how these should be used in practice. These include the GAME, GAMES and RIGOS projects and the Yellow and Purple Book guidance documents. This training also provides hands-on guidance on best practice approaches to breaking up real plant geometries into obstructed regions based on the literature.

Learning objectives
Upon completion of this course, participants will have a good understanding of the theoretical basis of the congested explosion modelling and vulnerability modelling features available in the Phast Risk explosion modelling extension. This course focuses on the theorectical basis of the modelling in the software, not software usage per-se, both in terms of the calculation of effects from explosions and the impact of different vulnerability characteristics on overall risks to people.

Target group
Experienced risk analysts with previous experience using Phast Risk who need to carry out detailed risk modelling calculations involving explosions and need a good understanding of the theoretical basis of the explosion modelling capabilities. The training does not cover Phast and Phast Risk usage and assumes delegates are already familiar with the software, including the functionality provided by the explosion risk extension.
