Course Description
The international and US standards for Safety Instrumented Systems (SISs), IEC 61511 and ISA 84, require that Safety Integrity Levels (SILs) be determined for Safety Instrumented Functions (SIFs) to meet tolerable risk criteria. The standards identify several methods that can be used for this purpose including Layers of Protection Analysis (LOPA), risk graphs, and risk matrices.
This course explains how these three methods can be used. Course participants learn a procedure for SIL determination and practice performing SIL determination using each method.
What you will learn:
- Process safety concepts for SIL determination
- Requirements of SIS standards for SIL determination
- The role of hazard and risk analysis in the allocation of safety functions
- What is meant by a hazardous event
- How to identify SIFs in a process
- How to use risk tolerance criteria in SIL determination
- Procedure for SIL determination
- Use of risk matrices to determine SILs
- Use of risk graphs to determine SILs
- Use of LOPA to determine SILs
Who Should Attend
Facility personnel who are involved in implementing standards for safety instrumented systems.
Prerequisites
An understanding of LOPA is required. Attendance at Primatech’s training course, Layers of Protection Analysis (LOPA) for Process Safety, meets this requirement. Knowledge of the IEC 61511 / ISA 84 standards on safety instrumented systems and a technical background are desirable.
Credits
0.7 Continuing Education Credits (CEUs) or 7 Professional Development Hours (PDHs) are awarded.
