Course Overview

Safety Instrumented Systems: A Lifecycle Approach (EC50) focuses on the engineering requirements for the specification, design, analysis, verification, and justification of Safety Instrumented Systems (SIS) used in the process industries.

Participants learn how to determine Safety Integrity Levels (SILs), apply Layer of Protection Analysis (LOPA), and evaluate whether proposed or existing systems meet the performance and documentation requirements defined in ISA/IEC 61511 (ISA-84).
