    ISA EC50 Instructor Interview

    Description:

    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 (IEC61511) standard.

    This course is required for the ISA84 Safety Instrumented Systems Certificate Programs. You can register for the course only or for the certificate program which includes course and exam.

    Those who successfully complete this course and pass the exam receive the designation of ISA84 SIS Fundamentals Specialist.

    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:

    "The lab sessions were very helpful. I was very pleased with the course. More so than any other technical course I have been to. I feel that I really learned something."
    - Shawn Coughlan
    • 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

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