Safety Instrumented Systems: A Life-Cycle Approach

ISA 84 Level IaeSolutions is offering the ISA course EC50, Safety Instrumented Systems: A Life-Cycle Approach on Monday February 10th to Friday February 14th.  This course is part of the ISA/IEC 61511 SIS Fundamentals Specialist Certificate Program.   Your course registration includes your registration for the exam.

Safety Instrumented Systems: A Life-Cycle Approach (EC50) 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 (IEC61511) standard.

Those who successfully complete this course and pass the exam receive the designation of ISA/IEC 61511 SIS Fundamentals Specialist Certificate.

 CEU Credits: 3.2
 Length: 4.5 days                                                       Course Hours: 8:00 a.m. – 4:00 p.m.

Certification of Completion: A Certificate of Completion indicating the total number of CEUs earned will be provided upon successful completion of the course.

You will be able to:

  • Differentiate between process control and safety control
  • Implement the ISA84 (IEC 61511) standard
  • Evaluate process risk levels
  • Select Safety Integrity Levels (SILs) for Safety Instrumented Functions (SIFs) 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, imperfect manual testing, and bypassing
  • Determine optimum system test intervals
  • Specify and select safety instrumented systems
  • Apply the documentation requirements for process safety management, regulations, and industry standards

 

You will cover:

  • Introduction: Accidents and Resulting Regulations | Lessons Learned From Past Accidents | Standards & Guidelines of Interest
  • Scope & Safety Life Cycle: Management Issues | Design Life Cycle |
  • Safety Layers: Independent Safety Layers | Separation of Control and Safety
  • Risk, Hazard Analysis, Safety Integrity Levels: Hazard Identification | Risk Assessment | Selecting Safety Integrity Levels | Layer of Protection Analysis
  • Failure Modes & Reliability Concepts: Safe vs. Dangerous | Failure Mode vs. Technology | Failure Rates | Modeling Techniques | Test Intervals | Fault Tolerance Requirements
  • System Technologies: Pneumatic | Relay | Microprocessor | Field Devices | Certification | Prior Use
  • System Design: Requirements Specification | General Design Issues (Environment, Interfaces, Bypasses, Resets, etc.)
  • Operations and Maintenance: Installation | Operation & Maintenance | Testing | Management of Change | Decommissioning

 

Classroom/Laboratory Exercises:

  • Calculate device failure rates
  • Model system performance for relay and software-based logic systems
  • Model the impact of different configurations, field devices, automatic diagnostics, manual test intervals, common cause, and imperfect manual testing and bypassing
  • Determine the SIL (safety integrity level) of a sample functions and design a system to meet the performance requirements
  • Classroom Copies of ISA/IEC 61511 standards will be provided for your use during the course

 

A hand-held/scientific calculator should be brought to class.
