Safety Integrity Level (SIL) Training

[2-Day Basic Training]

Safety Instrumented Functions (SIFs) is established as means of instrumentation to bring the process to a safe state. The key objective of the Safety Integrity Level (SIL) Classification is to determine the required reliability of the SIFs based on an assessment of the impacts on the Personnel Health and Safety, Economic and Environmental consequence. The study involves defining the elements forming the SIF, identifying the design intent, identifying the initiating events along with the frequencies, development of the incident scenario if the SIF fails on demand, as well as Independent Protection Layers (IPLs) to safeguard the hazardous scenario.


  • Use of SIL Classification methodology as per IEC 61511 and IEC 61508 to determine the SIL requirement for a Safety Instrumented Function (SIF);
  • Determining SIL level based on the severity of the consequences to personnel safety, environment pollution and asset damage;
  • Determining Independent Protective Layers as additional mitigation measures to reduce the SIL requirement.
  • Determining SIL Classification for final element.

Who should attend?

  • HSE/Safety Engineer, Process Engineer, Instrumentation Engineer, Operation, Maintenance Engineer.
