On demand course.

This modular online course aims to provide delegates with an understanding of the implementation of the Safety Instrumented Functions (SIF) life cycle.

Many facilities use Safety Instrumented Functions (SIFs), designed to reduce the likelihood of a hazardous event and hence maintain the ALARP status. SIFs are generally designed and operated in conformance with IEC 61508/ IEC 61511. The codes address SIF design, selection and ongoing management in terms of a life cycle.

Course outline

Module 1 

  • SIF life cycle phase 1
  • SIF life cycle phase 2

Module 2 

  • Introduction to HAZOP and LOPA
  • SIF life cycle phases 3 and 4 

Module 3

Learning outcomes

By the end of this course you will be able to understand:

  • the principles of the SIF life cycle
  • how to determine the SIL rating for a SIF, using both risk graphs and LOPA
  • how the SIL is verified
