Consequence Modelling Techniques

Topic Safety

CPD Hours 4

Price £235 + VAT


This new online course will help you understand a range of consequence modelling techniques, including their advantages and limitations. You’ll learn how to define the possible outcomes of hazardous material release and the impact of hazards on people, environment and property.

This four-module course will also demonstrate how to define source terms, discuss different approaches to consequence modelling and regulatory requirements for consequence modelling.

Learning outcomes

By the end of the course, you will understand:

  • how to identify a set of major accident scenarios on a facility handling hazardous materials
  • which type of models available for different scenarios and which are appropriate at different stages of plant design or operation
  • the limitations of the various model types
  • how to define the possible outcomes of hazardous material release eg fire, explosions, and toxic effects
  • the requirements of modelling these hazards
  • the possible impact of hazards on people, the environment and property
  • the importance of defining source terms (initial conditions), including uncertainty
  • regulatory requirements for consequence modelling.

Who will benefit

Project and plant managers, safety managers on COMAH sites responsible for preparing safety reports and interpreting modelling results, professionals using consequence models and/or their results and want further guidance on the bases, validity and uses of modelling or those new to the field of process safety who need to understand the potential scale of accidents and the consequences.
