An Introduction to Functional Safety and SIL for the Process Industries

An Introduction to Functional Safety and SIL (Safety Integrity Level) in the Process Industries (Oil & Gas, Chemicals, Power Generation, etc)

I.    INTRODUCTION
Functional Safety is a relatively new concept in the world of safety (and industry as well). This whitepaper seeks to explain the concept of Functional Safety and related concepts of demand, safety integrity level, Safety Instrumented Systems and standards used in the area of Functional Safety, to technical professionals, who do not have any background in functional safety. It also explains the importance of Functional Safety Management known as FSM for short, in industry.

II.    WHAT IS FUNCTIONAL SAFETY? WHAT IS A SAFETY FUNCTION?
Safety is simply defined as “freedom from harm”. In colloquial terminology we use the words, risk, hazard, harm and unsafe interchangeably. However, all these terms are actually completely different. Before we start with the concept of Functional Safety, let us understand the differences between hazard, risk and harm.


It is now clear that the Functional Safety Manager should be a technically competent and experienced person, who understands Functional Safety very well. He/She should have adequate training and certification that demonstrates the knowledge and competence in Functional Safety. Also he/she should have people management skills, project management skills and co-ordination skills.

Functional Safety has grown in importance over the last decade. It is not just enough to understand Functional Safety, follow the appropriate and relevant standards such as IEC 61508 and install Safety Systems. It is also important to understand and adequately manage Functional Safety over the entire lifecycle of the plant or equipment. This is known as Functional Safety Management and it is skill that will only increase in demand in the years to come, as emphasis on safety increases.
