Course Description

Achieved Safety Instrumented Functions (SIL)

Achieved Safety Instrumented Functions (SIL): 2 Day Training course for Engineers and Designers

This Achieved Safety Instrumental Functions (SIL) training course aims to provide delegates from the engineering and design industry with a thorough grounding in the underlying principles of the IEC 61511 functional safety standard.

Using a combined training approach involving both lectured learning and practical exercises this course guides delegates through basic principles to advanced issues relating to SIL (Safety Instrumented Functions.)

Delegates can expect the following learning outcomes from completing this course:

  • Understand the concepts underpinning SIL calculation
  • Identify what information is essential before starting the SIL calculation
  • Apply correct formulae for serial or parallel instrument configurations
  • Derive instrument failure rates from commonly available sources
  • The benefits and disadvantages of manufacturers certificates
  • Appreciate the complexities of a ‘human in the loop’
  • What checking and approval is needed for different Safety Integrity Levels
  • Calculate the SIL

Suitability - Who should attend?

This course is aimed at engineers and designers involved in calculating or verifying the performance of new or existing safety instrumented functions.

Training Course Content
