You are well aware of the role of Functional Safety and Safety Instrumented Systems (SIS), in protection of assets and people. In recent years, there have been extensive studies on the best ways of making our process plants safer and the conclusion is, that by just doing one thing right, which is -increasing the reliability of the Safety related Instrumentation and Control systems in a plant, we can make these plants much safer. It is not enough for automation & control professionals to know about just process control systems or instrumented systems, you need to know about Safety Instrumented Systems too. Taking this Abhisam Safety Instrumented Systems training course is by far the fastest and easiest way of learning SIS online and getting certified.

Safety Instrumented Systems- Why are they important?
Companies have realized that negligence (or ignorance), in respect of an instrumented system and especially of a Safety Instrumented System can be really disastrous, literally. Look at just a few recent cases that have been listed below (scroll down to see).
Incident: Caribbean Petroleum, Puerto Rico, 2009– Accident caused due to non working of the overfill protection instruments (part of the Safety Instrumented System). A massive fire and explosion sent huge flames and smoke plumes into the air at the Caribbean Petroleum Corporation near San Juan, Puerto Rico. The resulting pressure wave damaged surrounding buildings and impacted moving vehicles. The final report into the incident was released by the US Chemical Safety Board and it was non working of the overfill protection system (part of the Safety Instrumented System).
Morgantown, North Carolina,USA, 2006
Explosion at a polymer manufacturing plant led to total damage of the facility, with a human fatality and several injuries. Investigations found out that a lack of process safety standards and non implementation of automatic interlock systems (in other words, logic solver of the Safety Instrumented Systems) as the root causes of the disaster.
Buncefield, UK, 2005- non working of the Overfill prevention system (part of the Safety Instrumented System)
The Buncefield industrial disaster was one of the biggest disasters to strike the chemical and petrochemical industry in Europe in recent years. The blasts that occurred were so loud, they were heard as far away as France! (Buncefield is in the UK) The root cause was found out not because of the logic solver but due to a bypassed level switch (part of the Safety Instrumented System) on the site.
Of course, you agree, that safety instrumented systems are essential and are operational in many plants and facilities around the globe. But mere operation and existence of such a system, does not ensure, that it will always work as designed , is it not?
You need to know it in depth, to make it work for you.
To make it work for you, you need to know these systems thoroughly ( We mean not from a programming point of view but from a users point of view). You need to get trained in all the concepts and ideas, including applicable codes and standards, ( including international Standards for safety instrumented systems such as IEC 61508:2010 and IEC 61511:2016, ISA S84) plus good engineering practices of these critical Systems. Note that here, when we refer to such systems, we also include Emergency Shutdown Systems (ESD), Safety Shutdown Systems, High Integrity Pressure Protection Systems (HIPPS) and all similar systems that are used to ensure the safe operation of plant and machinery, using highly reliable instruments, controllers, valves and other electrical and pneumatic/hydraulic elements and devices.
A SIS is of several safety instrumented functions, also known as SIFs. Many of these SIFs together form a SIS. Each SIS is therefore composed of several sensors, logic solvers and final control elements like actuators, control valves and dampers. However, the jargon associated with these sophisticated safety instrumented systems is so tedious and even confusing, that even experienced professionals cringe at the mention of Triple Modular Redundant, 2oo3 voting, SIL 3 or IEC 61508.

Free SIS information and Whitepapers
Integrated SIS DCS
Earlier the BPCS (in many cases a DCS) and SIS used to be completely different systems, with almost no connection between them. Lately, however there have been many vendors that provide”Integrated” SIS and DCS. How good are these? What are their advantages? Are there any risks in this approach?
Introduction to Functional Safety and SIL
This free Introduction to Functional Safety and SIL whitepaper gives you an easy to understand guide to these topics. Learn about the Safety Lifecycle, Functional Safety Management, Safety Integrity Level, basics of international standards IEC 61508 and IEC 61511/ ISA S84 and more.
