Process Risk Assessment

Topic Safety

CPD Hours 12


This course will help you to develop the skills and knowledge to identify, assess and communicate process risks from a safety, environmental or business perspective, from a simple qualitative approach to fully quantified assessments.

Learning outcomes

By the end of the course you will understand:

  • the concepts of individual and societal risk 
  • risk tolerability
  • the 5-stage risk assessment process, the different types of process risk assessment and when to apply them
  • techniques for qualitative, semi-quantitative and quantified risk assessment (QRA) including risk matrices, bow tie analysis, LOPA, occupied buildings risk assessment and fault tree/event tree analysis (FTA and ETA)
  • environmental risk assessment using a risk matrix-based approach (CDOIF methodology)
  • the principles of ALARP demonstration.

Who will benefit

  • staff involved in the risk assessment process including supervisors, managers and directors 
  • plant/process operators including maintenance functions 
  • process safety engineers and loss prevention specialists 
  • chemical engineers working toward Chartered status.
