Functional Safety is an important part of industrial safety and is used in many industries and business sectors, to protect plants and other assets, people and the environment.

Today, modern plants and facilities including those in sectors such as Oil Extraction and refining,  Gas processing, Chemicals, Mining & Metals, Pulp & Paper, Power Generation, Pharmaceutical manufacturing, all use Safety Instrumented Systems extensively, to have safe and reliable operations.

Also, these industries all over the world, need to be compliant to international standards such as IEC 61508 and IEC 61511 (ISA S84 in the US). These systems need to be designed correctly, engineered, built, installed, commissioned and maintained as per these standards in order to really ensure the safety of assets, people and the environment. They also need to be secure against various cyber security threats.

This Abhisam e-learning course covers all that you need to know about these systems at a fundamental level and also get certified.

You need not refer to boring, outdated and irrelevant books to learn it. 

This self paced e-course, is a highly engaging course with text, Interactive Animations & Simulations, real life examples, videos and interactive assessments! No need to attend boring classroom style sessions or Zoom lessons that leave you frustrated.

This Functional Safety and SIS e-learning course is a superior alternative to live training and can be taken anywhere and anytime. You can take the associated exam and earn a certificate and electronic badge for the Functional Safety & SIL Course (Level 1).

The Self Assessment test helps you evaluate yourself before you take the certification exam. It can be considered as a Functional Safety mock test.

Just get this Functional Safety e-learning course today and for a much lesser price that you would be paying for any other course out there!

Note that it includes all the necessary information that you need to know about Functional Safety and SIL including SIL Determination with examples plus cybersecurity aspects of SIS. 

NO classrrom course covers all this at such a low price.

Can I not get this information free from elsewhere?

There is a myth  “Just Google it”

Unfortunately it is not true. If you Google for terms like Functional Safety or SIL or cyber security of SIS,  you are likely to get a large number of related articles, videos, ebooks and other material. It will take you a long time to go through it and at the end of this whole exercise you may

      1.  Not be able to string it all together-most information on the internet is in bits and pieces (although large ones). It is not put out there as a logical construct or in any sequential manner. This is to be expected since it is all from different sources who may have different competencies, different interests and view points.
      2.  Be more confused than what you were before you started searching for it, after wasting several days of your time.
      3. You may not be sure that whatever information you get is current (updated) and authentic. Standards and Practices keep getting updated all the time and you must know the most current ones.
      4. You will not be getting any certificate for your efforts.

Plus you will spend several hours of your time doing all this for zero returns on your investment!

On the other hand, when you take this Abhisam Functional Safety course, you know that

      1.  It is very carefully made, with subject matter experts in the field of FS and SIS, with logical progress from one module to the next.
      2. Utilizes animations and simulations to help you understand concepts real quick. These are not available anywhere else.
      3. Get access to a real life situational videos, that clearly help you understand actual situations in industry.
      4.  Earn a Certificate when you pass the associated exam and also get an electronic badge that can be displayed online on places such as LinkedIn. Get Noticed as an Expert!

Can I not simply buy a book? That will be much cheaper!

Of course, you could always pass this up and decide to go for  buy a book on this topic, but, remember that there are some disadvantages with this approach

      1.  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.
      2.  Some of these books may be outdated and obsolete.
      3.  Watching an animated simulation makes you grasp a concept much faster than merely reading about it.
      4.  Finally, nobody gives you a certificate if you simply read a book!
