ISA-84 training course

Safety Instrumented Systems – Design, Analysis & Justification

This course focuses on the engineering requirements for the specification, design, analysis, and justification of safety instrumented systems for the process industries. Students will learn how to determine safety integrity levels and evaluate whether proposed or existing systems meet the performance and documentation requirements defined in the ISA-84 standard.

You will be able to:

Differentiate between process control and safety control
Understand and implement the ISA-84 standard
Evaluate process risk levels
Determine Safety Integrity Levels (SILs) using a variety of techniques
Analyze the performance of different logic system technologies
Analyze the performance of various sensor, logic, and final element configurations, as well as the impact of diagnostics, test intervals, common cause, system size, and more
Determine optimum system test intervals
Specify and select safety instrumented systems
Satisfy the documentation requirements for process safety management, regulations, and industry standards

You will cover:

Introduction: Danger of Overconfidence and Complacency | Lessons Learned From Past Accidents
Guidelines and Standards: ANSI/ISA | AIChE | IEC | HSE | OSHA
General SIS Design Considerations: Design Life Cycle | Separation of Control and Safety | Independent Safety Layers
Hazard and Risk Assessment: Hazard Identification | Risk Assessment | Determining Safety Integrity Levels | Layer of Protection Analysis
Failure Rates & Modes: Safe vs. Dangerous | Failure Mode vs. Technology | Failure Rates | Test Intervals
System Technologies: Pneumatic | Relay | Microprocessor | Field Devices | Certification | Prior Use
Operations and Maintenance: Installation | Bypassing | Testing | Management of Change | Decommissioning
Class Examples: Putting it all together

Classroom/Laboratory Exercises:

Calculate device failure rates and determine safe vs. dangerous performance
Model system performance for relay and software based logic systems
Model the impact of field devices, automatic diagnostics, manual test intervals, common cause, and more
Determine the SIL (safety integrity level) of a sample processes and design an SIS to meet the performance requirements
