This technical briefing is offered for public live-streamed delivery. It is also available for in-house live-streamed delivery.
Description
LOPA is a simplified form of risk assessment. It is used to comply with industry standards and regulatory expectations. The risk of hazard scenarios is evaluated and compared with risk tolerance criteria to decide if existing protection layers, or safeguards, are adequate, and if additional safeguards are needed. LOPA considers only safeguards that are determined to be Independent Protection Layers (IPLs). The qualification of safeguards as IPLs is the central part of performing LOPA studies.
This technical briefing provides guidelines for qualifying safeguards as IPLs. It is intended for practitioners who are new to LOPA studies and those who need a refresher on the latest approaches. Attendees receive an electronic copy of the technical briefing materials.
What you will learn:
- Qualification criteria for IPLs
- Meaning of dependent failures
- Importance of common cause failures
- Sources of common cause failures
- Types of protection layers
- Conditions for human actions to be credited as IPIs
- Measures that are not normally considered to be IPLs
- Guidelines for qualifying safeguards as IPLs
