Course Description
Learn the Latest Risk Assessment Technique
Layer of protection analysis (LOPA) is the newest methodology for hazard evaluation and risk assessment. On a sliding scale of sophistication and rigor, LOPA lies between the qualitative end of the scale (characterized by methods such as hazard and operability [HAZOP] analysis and what-if analysis) and the quantitative end (characterized by methods using fault trees and event trees).
Make Consistent Decisions on the Adequacy of Layers of Protection
LOPA helps the analyst make consistent decisions on the adequacy of the existing or proposed layers of protection against an accident scenario. The decision-making process is ideally suited for coupling with a company's risk-decision criteria, such as comparison to targets set by your company for controlling risk to "as low as reasonably practical (ALARP)."
Learn All You Need to Know About LOPA
In this 2-day course, you will learn how to apply LOPA. The course will cover fully all the topics in the concept book Layer of Protection Analysis (Center for Chemical Process Safety [CCPS], 2001).
What You Will Learn
- Rules for how and when to use LOPA
- How to develop scenarios for either a new process or changes to a process
- How to develop scenarios starting from a qualitative hazard evaluation (e.g., HAZOP analysis)
- How to estimate the frequency category for the initiating event of a scenario
- How to determine the consequence category for the unmitigated scenario
- How to determine which protection layers meet the criteria for independence and uniqueness and for audits
- How to calculate the scenario risk
- How companies around the world are using LOPA to determine which scenarios pose the greatest risk and which scenarios have residual risk that is too high
The course is divided into four major sections:
Risk Judgment Fundamentals
A company should focus its resources on high-risk scenarios. We will explain how companies around the world are using risk acceptance criteria and risk judgment tools to determine which scenarios pose the greatest risk and whether the current risk is unacceptable.
Risk Acceptance Criteria
You will learn how to help your company establish acceptable risk criteria. You will also learn how to explain these criteria in a risk matrix so that they can be applied during (1) reviews of new designs, (2) management of change, (3) hazard reviews of existing systems, and (4) resolutions of recommendations.
Risk Judgment Techniques
To judge the residual risk of a scenario, you will learn qualitative, semiquantitative, and quantitative approaches for combining (1) the consequence of a scenario, (2) the likelihood of an initiating event, and (3) the effectiveness of the safeguards. Finally, you will have concrete tools for judging when your layers of defense against an accident are acceptable versus when you need further safeguards.
Special Application of LOPA
LOPA can be used for any risk-based decision. And it is particularly useful for (1) moving or strengthening control rooms and equipment because the risk of explosions otherwise cannot be reduced sufficiently and (2) deciding on the integrity level necessary for safety interlocks. The course will present specific instruction for how to make these evaluations. Students will work several exercises to apply what they learn.
Workshops to Help You Learn the LOPA Skills You Need
Most of the course time will be spent in workshops and exercises to learn the rules and the fundamental skills needed to effectively apply LOPA.
Prerequisite(s)
Background and prior training in qualitative hazard evaluation methodologies (such as previous attendance at Course 110, Process Hazard Analysis Leader Training Using the HAZOP and What-if/Checklist Techniques, or the equivalent) are strongly recommended because LOPA builds on the skills and knowledge needed for hazard evaluations.
