CHE6011N03: Layer of Protection Analysis
About This Course
- Anatomy of an incident
- Difference between safeguards and independent protection layers (IPL)
- What is a "safety instrumented system (SIS)”, a “safety instrumented function (SIF)”, a “safety integrity level (SIL)” and a “basic process control system (BPCS)”?
- LOPA/SIL assessment: LOPA steps
- Initiating events: Types and likelihood
- Frequency modifiers
- Estimating consequences
- Type of IPLs
- Active BPCS and alarms
- SIS and pressure relief devices
- Passive fire and gas deluge systems
- Basic IPL rules
- IPL integrity
- Determining scenario frequency
- Pros and cons of LOPA; typical team members
- SIL study and reporting
- Safety lifecycle of SIS
- Overview of safety standards: IEC 61511/61508, ISA TR84.00.02-2002
What You'll Learn
In this practical 2-day workshop, you will learn about the fundamentals of LOPA, its advantages and limitations, and how you can leverage it to make decisions about layers of protection used in a hazard scenario. By the end of the workshop, you will be able to:
- Define an independent protection layer (IPL)
- Differentiate between safeguards and independent protection layers (IPL)
- Decide if a process needs a safety instrumented system (SIS)
- Assign a safety integrity level (SIL) to SIS
- Understand the safety lifecycle of SIS
Entry Requirements
