Safety Instrumented Systems
Covering more than any other course available today at a price that is less than any other!
Dear Friend,
You are here, reading this page, because you are well aware of the role of 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 Instrumentation and Control systems in a plant, can make these plants much safer.

On the other hand, negligence (or ignorance), in respect of Safety Instrumented Systems (SIS) can be really disastrous, literally. Look at just a few recent cases below.
MODULE 1- Introduction to SIS
  • What are Safety Instrumented Systems?
  • Basic Ideas about SIS
  • Functional Safety
  • Instrumented Systems & Safety Instrumented Systems
  • BPCS
  • BPCS and SIS
  • Safety Instrumented Function
  • Safety Instrumented Function-2
  • Safety Instrumented Function-3
  • Emergency Shutdown Systems
  • Need for a separate SIS
  • Simulation exercise
  • Learnings from the exercise
  • Typical architecture
  • Integrated BPCS & SIS
  • Integrated BPCS & SIS-2
  • Examples
  • Differences between BPCS & SIS
You have seen how detailed and comprehensive this course is, as compared to any other course anywhere. So what are you waiting for?

Includes how to assess and also verify Safety Integrity Level (SIL)
Caribbean Petroleum, Puerto Rico, 2009
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. Preliminary cause found, was non working of the overfill protection system (part of the Safety Instrumented System).

Petrolia, Pennsylvania, USA, 2008
Thousands of residents of surrounding areas had to be evacuated to safer places when there was a release of large quantities of Oleum (fuming Sulfuric acid), from a chemical plant. The root cause was determined to be non implementation of a proper Safety Instrumented System.

Danvers, Massachusetts, USA, 2006
Massive explosion at an ink processing plant causes destruction of plant as well as surrounding homes, injuring many residents of surrounding areas. Cause? Lack of safety interlocks and automatic shutdown systems (in other words a Safety Instrumented System) in the plant.

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, Safety Instrumented Systems) as the root causes of the disaster.

Buncefield, UK, 2005
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 to be a probable malfunctioning Safety Instrumented System in one of the plants on the site.

The list goes on and on.....

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 ( I 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 of Safety Instrumented Systems. Note that here,  when we refer to Safety Instrumented Systems(SIS), 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 instruments, electrical and pneumatic/hydraulic devices.

However, the  jargon associated with these sophisticated process control systems is so put-offing and even confusing, that even experienced professionals cringe at the mention of Triple Modular Redundant, 2oo3 voting, SIL 3 or IEC 61508.

Does it really have to be this way?

No! Not really.

You can get this e-learning course on Safety Instrumented Systems(SIS) and learn all about these systems, in the comfort of your home or office.

Just download this Safety Instrumented Systems e-learning course today and for a fraction of the price that you would otherwise pay for a classroom training course, learn everything that you wanted to know about SIS (but didn't know whom to ask).

Of course, you could always pass this up and decide to go for that seminar or classroom training, whenever that is offered , or buy a book on this topic,


remember that any of the following things can happen.....

a) this low price will not last for long

b) you will forget all about this, till the time comes for you to explain to somebody higher up, as to why you installed the 2oo3 Safety Logic Solver  instead of the alternate 1oo2 Logic Solver , OR (God forbid)-you have to explain to a government inspector why you felt that SIL 1 was adequate for your Safety Instrumented function instead of a SIL 3 that he felt should have been required.

c) You forget about this e-learning course completely. Then you enroll yourself in an expensive $ 3000 classroom course, travel halfway around the globe to attend it, spend some more of your undernourished training budget on it  and then forget whatever you learned when the time comes to finally apply the concepts learned in your work.

e) You decide to skip this offer and opt to buy a book (or books) on this topic. However, there are a couple of problems. The first is that not a single book is available on the market, that covers all the topics that you need to know. On the other hand, there are a lot of things in every book, that you can safely skip, without missing anything. Thus, if you wish to source your knowledge of Safety Instrumented Systems from books, you will have to buy not one, but several. They also cost a pretty penny (are not cheap at all). The cost of just two of them will be more than the price of this course.

So, why don't you simply download this first of its kind training course on Safety Instrumented Systems and

a) Be assured that you have the best course on Safety Instrumented Systems in an e-learning format.

b) Have access always, to the entire course (it will reside silently on your computer  24/7), for as long as you retain your computer. There is no recurring license fee. This means once you buy a license, you can access it for as long as you wish, on the same computer.

c) Get a comprehensive course that has several Flash based animations and rich graphics, explained in a very simple to understand way, with accompanying text, that will remove all the "complexity" that is normally associated with this subject.

d) Join the hundreds of other engineers and technical professionals all over the world, who have downloaded this course and benefitted greately from it.

Go ahead and BUY IT.  Still unsure?    Download or View Online a free trial  of this SIS e-learning course here.

The investment amount is only $ 399 US at present , which will be increased shortly, once the early bird offer ends. Comparable classroom courses, from other providers, cost in the range on thousands of dollars.  There are also some so called online courses from some other service providers (they are just their stale powerpoint presentations from some earlier classes), but they are available in Modules (you have to pay a weekly access to view these modules). Plus you never know which modules you need, so you either end up buying a few and remaining still unsure about the subject OR you end up buying ALL and spend much more than this $399 now.

So DOWNLOAD this course and also take our FREE online exam that results in a Certificate of Competency, on passing, that you can show to your current or prospective employers or clients.
