Hazard Study Leaders

Topic Safety

CPD Hours 26

This is an IChemE approved training course and not delivered directly by the Institution. For more information about the course, contact the training provider directly.


The eight-stage hazard study process covers the full life cycle of a project. It starts at the feasibility stage of a project with a study of the inherent safety of the project concept.

The eight-stage hazard study process then mirrors the development phases of the project through detailed design, construction, commissioning, and ongoing operation. At each stage there is a hazard study technique which aligns with the needs and level of development of the project.

The course consists of a series of training modules that deal with the 8 hazard study stages, plus sessions on related topics designed to improve the capability of hazard study leaders. A series of team exercises are used for the process design stage hazard studies, to give the attendees a chance to put into practice what they have learnt during the lecture.

Additional dates are available visit the TÜV Rheinland Industrial Services website.

Learning outcomes

By the end of this course, you will understand:

  • TUVR’s techniques of the 8 stage hazard process
  • hazard study of continuous, batch, modifications, packages, procedures and other processes
  • revalidation of hazard studies and period review
  • how to develop the necessary skills to lead a team in carrying out hazard studies
  • organising and planning of meetings
  • technical understanding of event consequence in relation to loss of containment of toxic and flammable gases, the types and severity of each type of fire and explosion
  • alignment of hazard study with follow-on studies such as SIL assessment to provide line of sight from hazard to protection to support functional safety assessments
  • the incorporation of human factors in hazard studies
  • the pitfalls and limitations of hazard study techniques.

Who will benefit

Typical attendees would be process design engineers, safety managers, advisors, engineers and works or business technical personnel who are likely to lead hazard studies on a regular basis.
