about the course          

LOPA is a simplified form of risk assessment. It is used to comply with industry standards and regulatory expectations. Often it is used as an extension of process hazard analysis (PHA). LOPA is used to evaluate scenario risk and compare it with risk tolerance criteria to decide if existing safeguards are adequate, and if additional safeguards are needed. LOPA helps focus limited resources on the most critical safeguards.


WHat will you learn from the course?

At the end of the course, participants will be able to know:

  • Key process safety concepts used in LOPA
  • What you can accomplish using LOPA
  • How to identify scenarios for LOPA studies
  • How to address enablers
  • The meaning of independent protection layers (IPLs)
  • How to identify and qualify IPLs
  • The data needed for studies and their sources
  • How to estimate scenario risks
  • Criteria for making decisions on risk tolerability
  • A procedure for performing LOPA
  • How to document studies
  • Concept, purpose, and principles of LOPA
  • LOPA methodology
  • Selecting scenarios
  • The LOPA processes
  • Describing scenarios
  • Estimating initiating event frequencies
  • Independent protection layers and their reliability
  • LOPA study and documentation
  • Advanced aspects
  • Facilitating a LOPA study
  • Responsibilities and challenges

What is the course methodology?

This course teaches participants to perform LOPA studies. Worked examples are discussed and participants perform LOPA studies to gain experience using the method.

Who should take the course?

This course is designed for:

Process safety personnel, PHA analysts and others who need to apply or understand LOPA.

Prerequisite: An understanding of PHA and PSM and a technical background are desirable. If you are learning LOPA to comply with S84 / IEC 61511


  • What are the benefits of enrolling in this course
    This course will help you understand how significant scenarios are categorized and tolerable frequencies assigned for identified hazardous events. You will also learn to assign risk categories and determine how many Independent Protection Layers (IPLs) should be in place. The course also covers the specification and requirements for a protection layer to be accepted as an IPL.
