Electrical Hazard, Risks and Emergency Shutdown Systems Course
Introduction:
Functional process safety involves identifying potential hazardous events that can trigger a chain reaction that could lead to serious or catastrophic consequences. This training course explains the requirements of the international standards IEC 61508 and IEC 61511, for functional safety instrumented systems and, covers the entire life-cycle of safety instrumented systems, from determining what risk control systems are required through to decommissioning. This also includes the separation of basic process control systems and safety instrumented systems (SIS), layers independent protection (LOPs), how to determine safety integrity levels (SILs), technology choices, and field device issues. This training course primarily focuses on establishing conceptual and detailed design requirements, hazard analysis techniques, safety requirements specification, and the commissioning, operating, and maintenance procedures.
Course Objectives:
Upon the successful completion of the workshop, each participant will be able to:-
- Understand the requirements of the international standards IEC 61598 and IEC 61511
- Apply the IEC 61508 Safety Instrumented System Development ‘Safety Life Cycle’ model
- Determine the Safety Integrity Level (SIL) using risk assessment methods
- Understand the specifications of emergency shutdown protection requirements
- Establish specification requirements for the sensor, programmable logic controller and valves
- Follow Management of Change (MOC) procedures for control of future SIS changes
