Who should attend?

  • This course makes it possible to select the appropriate safety reviews and know how to implement them.
Audience :
  • This training is intended for personnel responsible for analyzing HSE risks during design or on existing installations.

Level : Foundation

Course Content

  • Module 1 - RISK & ACCEPTABILITY CRITERIA

      • Risk representation - Risks to people, property and the environment:
      • Potential hazard definition, risk levels, risk matrix, acceptable residual risk.
      • Safety reviews and risk analysis methods.
      • Objectives and implementation conditions: integration into the project planning.
      • Overview of the different reviews and methods. Impact on the Safety Management System (SMS).
      • Selection of the most appropriate method according to the context: new project, existing site and modifications, updating of hazard studies, authorization to operate...
  • Module 2 - HAZID METHOD (HAZard Identification)

      • Organization: identification of attendees, Scheduling the review, documentation, preparation, keywords list development.
      • Animation and conduct of reviews. HAZID review simulation on a simple case.
      • Preparation of the review report, follow-up and closure of actions/recommendations.
      • Fields of application of the HAZID method: APR, design reviews, constructability.
  • Module 3 - HAZOP METHOD (HAZard & OPerability)

      • Organization: identification of attendees, scheduling the review according to the studies development phase, documentation, preparation of the review, cutting of the PIDs.
      • Animation and conduct of reviews. HAZOP review simulation on a simple case.
      • HAZOP quantified.
      • Preparation of the review report, follow-up and closure of actions/recommendations.
      • What-if - Check-list: complementarity with the HAZOP method, interests and limits.
  • Module 4 - LOPA METHOD (Layer Of Protection Analysis)

      • Complementarity with HAZOP review. Principle of LOPA.
      • Concept of safety barriers - Determination of IPL (Independent Protection Layers).
      • Evaluation of the need for a SIF (Safety Instrumented Function).
      • Determination of the required SIL (Safety Integrity Level). Understanding of calculation elements (supplier data, databases).
      • Preparation/animation of reviews, according to IEC 61 511. Simulation of a LOPA on a simple case.
  • Module 5 - USE OF QRA (Quantitative Risk Assessment)

      • Quantitative Risk Assessment (QRA):
      • Overview of the method. Evaluation of the consequences. Probability, IRPA, societal risk, FN curves.
      • Scenario determination, Fault Tree analysis (FTA), Event Tree Analysis (ETA).
      • Bow tie: principle, construction and use. Safety barriers.
      • Use of QRAs: determination of design principles and criteria for the safety of an installation.
      • HSE concept. DAL (Design Accidental Loads).

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • actively participate in reviews, exploit the results of risk analysis,
  • select safety reviews according to the context (new project, modifications) and prepare them.

Ways & Means

  • Simulation of hazard reviews on simple processes.
  • Use of HAZOP manager © if requested in advance.
