This course facilitation of Safety Integrity Levels (SIL) assignment is directed at Safety Instrumented Systems (SIS) and Critical Controls in the process industry. The course focuses on the five current methods for determination of SIL according to IEC-61508/61511. Upon successful completion of this course the participants will be able to choose the correct SIL method, assign appropriate safety integrity levels for each safety function and facilitate the team in assigning SIL.
By the end of the program, participants will be able to:
- Assess the risk of a process hazard
- Establish tolerable risk guidelines
- Use common SIL selection methods
- Develop and quantify a simple fault tree
- Perform a Layer of Protection Analysis
- Consider multiple initiating events and outcomes in a LOPA study
