Safety Instrumented Systems & Functional Safety

Industrial processes can develop hazardous conditions that normal process control alone may not be able to prevent or contain. When critical parameters move beyond safe operating limits, Safety Instrumented Systems provide an independent layer of protection designed to detect dangerous conditions and move the process toward a safe state. The effectiveness of this protection depends not only on individual devices, but on correctly defining safety functions, establishing required integrity, maintaining independence, and ensuring reliable performance throughout the system lifecycle.
 

Boost Consulting & Training offers this course to develop a practical understanding of Safety Instrumented Systems and functional safety within industrial environments. Participants explore protection layers, Safety Instrumented Functions, SIL concepts, SIS architecture, sensors, logic solvers, final elements, lifecycle activities, testing, failure behavior, and performance verification. Practical exercises connect hazard scenarios with the engineering decisions required to establish and maintain effective safety functions.
 

The main concept of this course is to translate process hazards into clearly defined and dependable safety functions that reduce risk and continue to provide the required protection throughout their operating lifecycle.

• Explain the principles of functional safety and the role of Safety Instrumented Systems.
• Distinguish SIS from basic process control and other protection layers.
• Defining the purpose and components of a Safety Instrumented Function.
• Interpret Safety Integrity Level concepts and their relationship with risk reduction.
• Evaluate sensors, logic solvers, and final elements within SIS architectures.
• Recognize failure modes and factors affecting safety-function reliability.
• Apply testing, maintenance, and management principles across the SIS lifecycle.
• Evaluate safety-function performance and identify conditions requiring corrective action.
