Training Information

  • Duration:

    1 day

  • Prerequisite:

    The course is suitable for users who are already familiar with Safeti and who have previously attended SA-02 Safeti training. SA-03/06 Safeti advanced modelling and SA-13 Safeti advaced explosion modelling would also be of benefit, but are not mandatory.

    SA-12 Safeti congested explosion modelling extension


Safeti contains a new extension for modelling the risks from explosions. This new approach to explosion modelling takes account of the effects of congestion and confinement when calculating overpressure and impulse results. The new modelling allows the user to select either the Multi Energy and Baker Strehlow Tang explosion methodologies. This course describes how to use the extensive new functionality, including defining obstructed regions, buildings and associated vulnerability characteristics for a range of effect types and creating additional vulnerability sets for use when assessing exceedance criteria. The training goes on to describe the extensive results assessment capabilities of the much extended risk reporting functionality available in Safeti.

Learning objectives

Upon completion of this course, you will understand and be able to use the congested explosion modelling available in Safeti. This course focuses on the features available in the software and explains how to use these to build a model of your plant which includes congestion and confinement information as well as building specific vulnerability characteristics.

Target group

Experienced risk analysts with previous experience using Safeti who need to carry out detailed risk modelling calculations involving explosions. The training does not cover Phast (process hazard analysis software) and Safeti (QRA software) usage and assumes delegates are already familiar with the software.
