The important international standard for the safety related systems; the concept of petrochemical process safety life cycle; the design steps of safety instrument system (SIS); the failure safe control systems and methods for hazard and operability studies are introduced.

Safety Integrity relates to the ability of a safety-related system to achieve its required safety functions,and the safety integrity levels(SILs) are determined at the system requirements stage of the safety life cycle.
