Detailed Information

The Hazardous Area Instrumentation e-learning course enables you to learn all aspects of hazardous areas such as Area Classification, Material & Temperature Classes, Different methods of protection such as Explosionproof, Intrinsic Safety, Pressurization, Increased Safety and others, Fieldbus in hazardous areas, different standards used for hazardous areas, Inspection, maintenance and labeling of hazardous area equipment, certification of hazardous area equipment and more.

What are Hazardous Areas?

Many process plants, facilities, storage tank farms, ships, grain silos have hazardous areas, where the risk of fire and explosion is very high. Special precautions need to be taken in these areas to prevent this. The equipment that is used in this areas has to be of a special design, that will not trigger an explosion and has to be certified for use in such areas. The instruments and electrical devices used in such areas has to be of a type that will not trigger ignition and even if it does, it will not cause an explosion or fire. These instruments are referred to as hazardous area instrumentation and may include devices that use one or several methods of protection such as explosionproof, flameproof, intrinsic safety, pressurization, purging, increased safety, dust ignition proof and so on. Every technique is different and the Instrumentation engineer has to be familiar with the design and maintenance of each of these types of protection.

What do Learners say about this course?

We are the Gulf of Suez Petroleum Company, one of the major Oil & Gas production companies in EGYPT. I would like to express our good impression on such course. It is one of the most comprehensive, information rich and fun at the same time regarding Hazard area classification and its equipment installation practice.
Best regards for the abhisam company!

“Hazardous Area Instrumentation” helped me by its very clear and easy to understand demonstration, to explain and answer our client and colleague queries related to these subjects.
The result was amazing when I received their feedback after years of experience in this area.
I would recommend ” Hazardous Area Instrumentation” to people who need get some training in this field,before trying anything else, since I did this and found the Abhisam product the most effective and helpful among the other training products.
I wish success for Abhisam team for their great work.

Why this Hazardous Area Instrumentation Training Course?

Abhisam is the global pioneer in creating e-learning self paced courses for engineers and technicians all over the world. Hazardous Area Instrumentation is a specialized niche subject, but very critical for any Instrumentation & Control Systems engineer, Automation Engineer or technician to understand. This is because each of the protection techniques mentioned above is different in its design, installation and maintenance. A typical plant or a facility may have several different protection methods, so it is not enough to know just one.

Does it cover Hazardous Area Classification such as Zone 0, Zone 1, Zone 21, etc? What about Divisions?

Yes of course, you can see the detailed contents of the course by scrolling down below. One of the modules is on Hazardous Area Classification and what do the zones and divisions mean and imply but if you are looking for a Hazardous Area Classification course in detail (from the perspective of a Process Engineer rather than an Instrumentation or Electrical Engineer), then please refer to this course here. It deals in depth with classification. This hazardous area instrumentation course also has a classification module, but if you want a highly detailed course on how to classify a hazardous area and decide the extent of the zone or division, then that course has it in more detail.

Why should I buy this course? Is it a Power Point Presentation or a Video?

No, it is not a Power Point presentation or a video of a guy speaking. It is a full fledged self paced e-learning course with animations and simulations to explain key concepts. You will easily understand for example the differences between a threaded connection and a flanged connection from the hazardous area point of view, because of the animations that explain them. You will easily understand how an explosionproof junction box works or how a Zener barrier protects the Intrinsically safe circuit. There is an old saying that “A picture is better than a thousand words”. Well an animation is much better than a 1000 pictures. You can see some examples of it in the Demo. But there is really nothing like it anywhere else.

This training course has several modules (you will spend about 20 hours to complete all of them) that have text, animations & simulations to explain key concepts, situational videos, real life examples of how to design an Intrinsically safe loop for a temperature measurement application and so on. After you complete this course you can take the associated exam and earn a Certificate of Competency and an electronic badge via Credly.

Why can’t I get this for free?

You can of course trawl the internet and search for information but much of this course is created by our experts and is not available online anywhere else. One of the problems with the internet is that for general topics, there is a flood of information and you have tons of it. For specialized and niche topics, there is a lot of information but much of it may be either not authentic, or could be opinions presented as facts, or pure marketing hype or completely outdated.  Standards keep getting updated and you are expected to know the latest version of things. You could theoretically be able to search for everything and compile it and understand it, but you will likely spend at least a year doing it. You surely value your time, do you not? On the other hand, you need to only spend on this course, 16 hours of your time in going through it and then you can always earn a Certificate of Competency plus an electronic badge.

The material in this course is presented in a very structured and logical manner, so one thing leads to the next and you will have several “Ah-Ha!” moments. We do not think you could ever find all this information free on the internet.

Think of this as an investment of your time and money. The returns will be stupendous!

Can I not buy a book?

Of course you can!

However, you will not get all this information in a single book, you will have to buy several. Then, a book will not have animations, so it is kinda hard to understand. However even if you take one look at the animated workings shown in the Abhisam e-learning course, you will understand in a jiffy. Books may be having obsolete information, so that is not a viable alternative to a real training course.

Lastly nobody will issue you a certificate because you read a book.
