Safety Integrity Levels

Book authored by exida partners Edward Marszal & Eric Scharpf. The book describes a systematic method for selecting safety integrity levels for safety instrumented systems (SIS). Although numerous methods are being used in industry, the method presented, which includes layer of protection analysis, is rapidly becoming the most common. The reason for its popularity stems from its ease of use while providing accurate results. This method emphasizes accounting for existing layers of protection. By doing so, the SIS is not over-designed and over-priced. This method ensures that the maximum return on risk reduction investments is achieved.
