Safety integrity level (SIL) is defined as a relative level of risk-reduction provided by a Safety Function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a Safety Instrumented Function (SIF).This is qualitative tool.
A layer of protection analysis (LOPA) is a powerful analytical tool for assessing the adequacy of protection layers used to mitigate process risk. LOPA is semi-quantitative tool.
We will offer course to understand these techniques in better way. The course includes following,
- Safety Instrumentation System (SIS)
- IEC (610508 )Standard Requirements
- Safety Integrity Level (SIL) – Process of assigning SIL levels
- Risk Matrix and Risk Graph
- SIL Review and SIL Specification
- General Requirements of SIL
- Layer of protection analysis – A semi quantitative method
- Overview of LOPA
- LOPA procedure
- Scenario Selection & Consequence
- Initiating event
- Independent layers
- Actual Examples for one system.(For both SIL & LOPA)
- This course will provide clarity in these two methods.
- Participate effectively in SIL/LOPA sessions.
- The knowledge of SIL/LOPA is added advantage and provides an edge over others in industry.
