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 lifecycle.

This two-day course has been developed to provide education in the implementation of the SIF lifecycle and includes a number of syndicated exercises.

Learning outcomes

  • the principles of the SIF lifecycle
  • how to identify hazardous events with special focus on HAZOP
  • how to determine the SIL (Safety Integrity Level) rating for a┬áSIF, using both risk graphs and LOPA
  • how the SIL is verified
  • the ongoing management of SIFs, through operation, maintenance, modification and decommissioning.

Who will benefit

Anyone who would like to develop a broad understanding of SIFs and how they are managed, especially technical/process safety specialists.
