Functional Safety & SIS — Functional Safety

Course FS1E
Functional Safety & Safety Instrumented Systems (SIS)

Information about course FS1E

This Functional Safety & Safety Instrumented System (SIS) course covers key concepts from IEC 61511, focusing on safety lifecycle phases. Topics include:

Introduction: Basic definitions, SIF, SIS, SIL, failure types, diagnostics, and safety lifecycle overview.
Risk Analysis & Safety Requirements: HAZOP, Risk Graph, LOPA, protection layers, and Safety Requirements Specification (SRS)
Design & Implementation: SIF architectures, SIL calculations (PFDavg, MTTFS), and real-world examples
Operation & Maintenance: Proof testing, bypass management, maintenance, modifications, and Functional Safety Assessments (FSA).
Final Review: Key concept reinforcement.

Participants have 60 days of access to a virtual classroom with PDFs, videos, Excel templates, Word documents, and 17 instructional videos. The course includes practical examples, exercises, evaluation tests, and options for live sessions depending on the package. Certain versions also qualify participants for a certification exam.
