WHAT IS A HAZARDOUS AREA?
A Hazardous Area is a location in a manufacturing plant, storage area, tank farm or similar industrial facility where there is a risk of explosion and/or fire due to the nature of the materials handled there. These materials can be flammable or explosive or both and can include hydrocarbons such as Acetone or Methane, as well as seemingly “safer” materials such as iron dust, coal dust or grain. These places are also referred to as “classified locations”.
Abhisam has several hazardous area training courses that help you learn and get certified.
What is the purpose of hazardous area classification? Why should we bother?
The risk of a fire and/or explosion in a hazardous area (classified location) is much higher than a non hazardous area. We therefore need to take several steps that include engineering as well as operational measures to prevent accidents and disasters in these places. These are carrying out a hazardous area classification of the location (that divides the area into different zones such as Zone 0, Zone 1 or Zone 2 for liquids and vapors and into Zone 10, Zone 11 and Zone 12 for dusts and fibers). Note that the concept of Zone is from the CENELEC standards (later incorporated into the IEC standards) and is different from the Division Concept (Division 1, Division 2) that is in the National Electric Code (NEC) in the NFPA standard.
After this, we need to ensure that only those equipment that are suitable to be used in that particular area is allowed to be operated. So for example an Electric motor that is suitable for use in Zone 2 only, cannot be used in Zone 1 and so on. Note that these restrictions apply not only to electrical equipment but also to electronic instrumentation too.
What is ATEX?
If your plant or facility is in the European Union (EU), then you need to also comply with the ATEX directives.
ATEX is short for “ATmosphere Explosive” and is an EU directive that is applicable for all hazardous areas located in the European Union.
There are two directives, one is for owner / operators of the places that have hazardous areas (such as chemical manufacturing plants) and the other is for equipment suppliers, whose equipment is installed in these hazardous areas.
Note that this equipment includes not only Electrical & Instrumentation equipment, but even mechanical equipment like compressors and pumps.
These are referred to as “ATEX non-electrical equipment” and these too need to be suitable for use in these hazardous areas.
These directives are not just guidelines, they are the law and if you do not abide by them, you would be breaking the law.

Protection Techniques for Hazardous Areas
There are many ways to protect equipment in hazardous area from causing fires and explosions. These are called as protection methods and could be explosionproof, flameproof, intrinsic safety, pressurization, purging, increased safety, non-incendive and so on. There are other engineering methods to protect mechanical equipment as well, especially those that fall under ATEX.
Additionally, you also need to implement strict administrative controls in these places, such as carrying out a gas test before issuing a permit for hot work, not allowing stuff like matches and lighters into these areas and so on.
Both the engineering controls and administrative (management) controls together will ensure that your hazardous area will not be the scene of the next disaster.
Are Hazardous Areas only present in places like Oil platforms or petroleum refineries?
No. Although one might think that hazardous areas are only prevalent in the process industry (such as Oil & Gas, Chemicals, etc), in reality, they exist in many other locations as well such as grain silos, food processing plants, mines and coal handling facilities to name just a few.
Recently, there was a dust explosion in a factory that made aluminum alloy wheels for automobiles. So you can be sure that hazardous areas go beyond just the hydrocarbon processing industry.
You need to do a risk assessment for your workplace, if you believe that it may have places that could come under the definition of a hazardous area.
Abhisam has online courses, workshops & consulting services that cover hazardous areas, as well as other topics such as Process Safety, Occupational Safety, Functional Safety, Automation systems, IoT, Big Data and Cybersecurity. On this page, we will be only discussing Hazardous Area Instrumentation, Hazardous Area Classification, Intrinsically safe systems, ATEX and related topics .
You can explore other pages of the Abhisam site to get more information on HAZOP, LOPA, Hazardous Area Classification, Industrial Cybersecurity, Personal Protective Equipment and similar related subjects.
Hazardous Area Training
We have the following Online Courses / E-learning courses, related to Hazardous Areas. Each of these courses, consist of several modules, that have text, animations & simulations, graphics, assessments, examples, real life case studies that help you become a professional.
You can complete them from anywhere, such as from the comfort of your home, or office, or anywhere else.
You can either take them online over the internet (Online version), or download it to your Windows PC (when you buy the Standard version).
On passing the associated exam, you can get qualified as a professional, earn an electronic certificate with a unique ID number and a badge, that can be added to your Linked In Profile or other places online such as email signatures. This displays your qualifications and competencies to your colleagues, peers and potential employers and clients.
Hazardous Area Classification
Hazardous Area Classification is one of the first steps to be carried out if a location has been deemed to have the presence of flammable or explosive vapors, gases or dusts.
It should be done carefully to avoid either underclassification (could lead to unsafe conditions) or overclassification (could lead to cost escalation).
It covers the following topics in these modules:
a) Basic Concepts.
b) Properties of Materials.
c) Standards for Hazardous Area Classification (covers both CENELEC/IEC and NFPA).
d) Carrying out a Hazardous Area Classification (with detailed steps).
e) Practical Case Study of a Hazardous Area Classification project.
f) Common Myths about area classification.
g) Self Assessment Test.

Intrinsic Safety (IEC Code Ex-i) is one of the best methods to ensure protection in hazardous areas.
However, it is applicable only to low power systems such as Instrumentation, Electronics, Automation & Control systems. Implementing an Intrinsically safe installation is completely different from implementing other protection methods like explosionproof. The philosophy is totally different.
This self learning software based training course, is the easiest and fastest way to learn this subject at your own pace.
This course consists of the following modules.
1.Introduction to Hazardous Areas.
2. Basic Concepts of Intrinsic Safety.
3. Zener Barriers.
