Safety Instrumented Systems Verification— Practical Probabilistic Calculations William M. Goble and Harry L. Cheddie This book clearly explains how to do probabilistic calculations to accomplish safety integrity level (SIL) verification for safety systems. Starting with a description of the safety lifecycle, the authors show where and how SIL verification fits into the key activities from conceptual design through commissioning. The book not only explains the theory and methods for doing the calculations, the authors also provide many examples from the chemical, petrochemical, power, and oil & gas industries.

Safety Integrity Level Selection: Systematic Methods Including Layer of Protection Analysis Edward M. Marszal and Eric W. Scharpf This book describes a systematic method for selecting safety integrity levels (SILs) for safety instrumented systems (SIS). This method emphasizes accounting for existing layers of protection and ensures that the maximum return on risk reduction investments is achieved. This reference demonstrates the application of quantitative risk analysis techniques and tools to the problem of safety integrity level selection. They distill essential theory into a format that the average control systems engineer can quickly apply. It is a focused process for applying simple, yet powerful, tools of quantitative risk analysis specifically to the problem of selecting safety integrity levels for safety instrumented systems.
