Safety Integrity Level Selection - Systematic Methods Including Layer of Protection Analysis

This book describes a systematic method for selecting safety integrity levels for safety instrumented systems (SIS). This method emphasizes accounting for existing layers of protection. This method 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. The authors distill essential theory into a format that the average control systems engineer can quickly apply. This is not a generic theoretical dissertation, nor a comprehensive treatment of the topic of quantitative risk analysis. 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.
