Date and location
1 – 2 July 2015, Health and Safety Laboratory, Harpur Hill, Buxton,
Derbyshire, SK17 9JN
Layers Of Protection Analysis (LOPA) is a risk assessment method used to determine and hence demonstrate the ability of existing and proposed safeguards to protect against identified hazard scenarios and to meet predetermined risk based criteria.
The Process Safety Leadership Group (PSLG) prepared specific guidance for the applications of LOPA to determine the required safety integrity level (SIL) for overfill protection of highly flammable fuel storage tanks at sites similar to Buncefield. The course presenter was a member of the PSLG LOPA working group that developed the LOPA guidance. This course will draw on that guidance, its relevance to LOPA assessment in general, and pitfalls identified during the assessment of a large number of LOPA studies from the petrochemical industry.
What will the course cover?
- LOPA, uses and complexity
- When to use LOPA and when to consider QRA
- LOPA study prerequisites and preparation?
- LOPA target frequencies
- Human Factors
- Input data sources and uncertainty
- How to perform LOPA; LOPA rules and IEC 61511 requirements, scenario’s, conditional modifiers, enabling events, Independent protection/mitigation layers
- LOPA Outcomes; regulator expectations, ALARP considerations
- Example pitfalls associated with LOPA
- Case study examples
Who should attend?
The course is aimed at those engineers, managers and safety professionals who have a basic knowledge of risk assessment possibly gained through HAZOP studies and PHA studies, who would like to have an understanding of the LOPA method and how to apply LOPA and the pitfalls commonly associated with this type of analysis.
