Process Hazard & Risk Analysis - EFSTAS

Process Hazard & Risk Analysis


EFSTAS (formerly ProSalus) is an accepted course provider for the Process Hazard & Risk Analysis training of the TÜV Rheinland Functional Safety Training Program.

The FS Engineer (TÜV Rheinland) certificate demonstrates competency in the fundamentals of Functional Safety and provides a skill set that is transferable from one work situation to another and enables staff to fulfill responsibilities and to perform activities to recognised standards of competence on a regular basis, in order to

  • reduce risks
  • satisfy legal and regulatory requirements
  • meet the organisation’s safety and business objectives.

By understanding:

  • The PHRA principles and concepts in the internationally agreed standards IEC 61508 and IEC 61511,
  • The concepts and principles behind international standards that cover the area of process hazard and risk assessment and how and when to apply them including:
    • Hazard identification (HAZID) – ISO 17776
    • Hazard and operability study (HAZOP) – IE 61882
    • Event Tree Analysis – IEC 62502
    • Fault Tree Analysis – IEC 61025
    • Failure Mode and Effect Analysis – IEC 60812
  • Tolerable risk targets and the concept of reducing risks to as low as reasonably possible (ALARP)
  • The concepts and differences between qualitative, semi quantitative and quantitative risk assessment methods and when and how to apply them,
  • How to set up, use and apply the most popular safety integrity level (SIL) risk assessment methods: Hazard Risk Matrix, Risk Graph, Layers of protection analysis (LOPA).
  • The Interface between PHRA and the Safety Requirements Specification (SRS).

Target Group

Process Engineers, Safety Engineers and managers, Operations personnel and managers, Instrument engineers, as well as Maintenance engineers and personnel, consultants, advisors, persons involved in management, engineering, operations and safety of process operations as well as persons with HAZID study experience and who are involved in any of the early lifecycle phases for process hazard and risk assessment, allocation of safety layers and safety requirements specification.

Day 1

Will provide an introduction to the background, concepts and principles to be applied during the course, process hazard analysis, risk assessment, allocation of safety functions and process and functional safety compliance and competency management will be discussed in depth and participants will be introduced to the concepts of the international standards that cover this area of risk assessment and risk reduction.

The topics covered are:

  • Introduction to TUV Rheinland Functional Safety Program
  • PHRA background - IEC 61508 and IEC 61511
  • Process, Functional Safety & Competency Management
  • Introduction to Concepts and Principles of Hazards, Risk and ALARP
  • Application of Risk Reduction Techniques
  • Hazard Identification (HAZID)
  • Introduction to the Case Study – Session 1
  • Hazard and Operability Study (HAZOP)
  • Case Study – Session 2

Day 2

Develops on the case study work carried out in day one, taking the output from the HAZID and HAZOP studies and selecting appropriate techniques such ETA, FTA and FMEA and applying them to the course case study.

The topics covered are:

  • Hazard Risk Matrix Calibration and Application
  • Case Study – Session 3
  • Event Tree Analysis (ETA)
  • Case Study – Session 4
  • Fault Tree Analysis (FTA)
  • Case Study – Session 5
  • Failure Modes and Effect Analysis (FMEA)
  • Case Study – Session 6

Day 3

Develops on the case study work carried out in day one and two taking the output from the study and selecting appropriate techniques for selecting human factors and for Safety Integrity Level (SIL) Determination such HEART, PHEA, Risk Graph, LOPA, developing the SRS and applying them to the course case study.

The topics covered are:

  • Introduction to Human Error Analysis:
  • Human Error Assessment and Reduction Technique (HEART)
  • Predictive Human Error Analysis (PHEA)
  • Performance Influencing Factors (PIF)
  • Case Study – Session 7
  • Risk Graph Calibration and Application
  • Case Study – Session 8
  • Layers of Protection Analysis (LOPA)
  • Case Study – Session 9
  • Developing the Safety requirements Specification (SRS)
  • Case Study – Session 10
  • Format of Exam and preparation and close

Day 4

  • Exam


In accordance with the TÜV Rheinland Functional Safety Training Program:

  • A minimum of 3 to 5 years experience in the field of functional safety.
  • University degree or equivalent engineering experience and responsibilities as certified by employer or engineering institution.


Day four consists of a four-hour two-part proficiency examination with:

Part 1 = 30 multiple-choice questions – 1 Hour

Part 2 = Case Study with 7 milestone questions – 3 Hours


  • The training is led by Colin Easton a globally recognised expert in functional safety.
  • This training will provide participants with the knowledge for understanding and mastering the application of the most popular and internationally adopted methods and tools for identifying, assessing and managing the hazards and risks associated with their process operations, as well as the confidence to a take a more active role in the PH&RA process.
  • Successful participants, who also have sufficient experience, will achieve the prestigious FS Engineer (TÜV Rheinland) PHRA certificate.
  • The course will provide three days of classroom tuition and practical guidance, mixed with a practical case study based on a real life example, which will take the participant through the PH&RA process concluding with the development of the SRS.
