This course facilitation of Safety Integrity Levels (SIL) assignment is directed at Safety Instrumented Systems (SIS) and Critical Controls in the process industry.  

The course focuses on the five current methods for determination of SIL according to IEC-61508/61511. Upon successful completion of this course the participants will be able to
choose the correct SIL method, assign appropriate safety integrity levels for each safety function and facilitate the team in assigning SIL.

Upon successful completion of this course, the delegates will be able to:

Ø  Assess the risk of a process hazard

Ø  Establish tolerable risk guidelines

Ø  Use common SIL selection methods

Ø  Develop and quantify a simple fault tree

Ø  Perform a Layer of Protection Analysis

Ø  Consider multiple initiating events and outcomes in a LOPA study

This course is designed for engineers responsible for risk management decisions by determining SIL for each safety function, supervisory personnel who are responsible for determining SIS design standards and environmental and safety personnel who are responsible for reducing risk associated with environmental and safety incidents.
