This course is required for the ISA84 SIS Fundamentals Specialist Certificate Program

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 requirements.

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 (ISA84 SFS).

You will be able to:

• Differentiate between process control and safety control
• Implement the ISA84 standard
• Evaluate process risk levels
• Calculate 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
• Calculate 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: Danger of Overconfidence and Complacency | Lessons Learned from Past Accidents
• Guidelines and Standards: ANSI/ISA | OSHA | IEC | API | NFPA 
• General SIS Design Considerations: Design Life Cycle | Separation of Control and Safety | Independent Safety Layers
• Hazard and Risk Assessment: Hazard Identification | Risk Assessment
• Failure Rates and Modes: Safe vs. Dangerous | Failure Mode vs. Technology | Failure Rates | Test Intervals
• System Technologies: Pneumatic | Relays | Microprocessors
• Operations and Maintenance: Installation | Bypassing | Testing

Classroom/Laboratory Exercises:

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

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