Safety Instrumented Functions

Topic Safety

CPD Hours 14

Overview

This course is also being delivered online – view details >>

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

This two-day course will help you better understand all aspects of the SIF lifecycle, including how to determine the Safety Integrity Level rating for a SIF. The two most frequently used techniques (risk graphs and Layer Protection Analysis) for determining the required SIL are explained in the course. You will also learn about the most common pitfalls and how to overcome them. 

The course draws upon a range of exercises and case studies from different industry sectors.

Learning outcomes

  • The principles of the SIF lifecycle
  • How to determine the SIL (Safety Integrity Level) rating for a SIF, using both risk graphs and LOPA
