The safety instrumented system PDF was written to provide an overview of key terminology and aspects of the safety life-cycle according to IEC 61511 edition 2. The eBook is aimed at process industry functional safety applications of safety instrumented systems - SIS. It takes many years to master the technical aspects of functional safety and safety instrumented systems, and we believe that simplified guides can really help those who are on that journey.

The safety life-cycle for the process industry sector comes from the IEC 61511 standard. It is essentially a flowchart depicting the stages of different activities needed to assess hazards and then develop protection layers to prevent or mitigate risk. The life-cycle from IEC 61511 focuses on Safety Instrumented Systems (SIS) as one of the critical specialist protection layers that need careful specification, design, testing and maintenance.The safety instrumented system PDF contains around 30 pages of free information, including links to other resources and a unique safety life-cycle flowchart showing the inputs, procedures and outputs expected in real-life projects involving SIS.
