An Introduction to Safety Instrumented Systems in the Process Industries

[Webinar Replay] Safety instrumented systems monitor process variables such as pressure, flow, level and temperature. If any of those variables are outside their normal range, it means something is wrong, and these systems will bring the equipment and process to a safe state.
This introductory webinar will focus on the engineering requirements for the specification, design, analysis, and justification of safety instrumented systems used in the process industries. Topics will include:

  • Understanding the difference between process control and safety control
  • A summary of the ISA 84 (IEC 61511) standard lifecycle
  • The difference between safe and dangerous failures
  • An introduction to safety integrity levels
  • Items that need to be included in the safety requirements specification
  • What it takes to design systems (sensors, logic solvers, and final elements) to meet the different safety integrity levels
Key Take-Aways
  • Understand the basic lifecycle requirements of the ISA 84 (IEC 61511) standard
  • Learn the basics of determining the required safety integrity levels for the different safety instrumented functions that comprise a safety instrumented system
  • Gain an understanding of what needs to be included in the safety requirements specification, and why
  • Discover the basics of what it takes to design systems to meet the different safety integrity levels
