“The safety induction for new hires was handled smoothly. Elion brought their own AV equipment and kept the session engaging. We’re thinking of repeating this monthly.”
Zone Classification Services for Hazardous Areas
Last Updated: 2026
Zone classification identifies and categorizes areas where flammable gases, vapours, or combustible dust may create an explosion risk, so the right electrical and mechanical equipment can be selected. Elion classifies hazardous areas per IS/IEC 60079 and PESO guidelines, delivering classified-area drawings and a compliance report — trusted since 2010 across 30,000+ audits.
What is Zone Classification?
Zone Classification involves identifying and classifying areas where flammable gases, vapors, or dust may be present to prevent explosions and ensure operational safety. It is critical for industries like oil & gas, pharmaceuticals, chemical processing, and paint manufacturing.
Elion’s Zone Classification services help you comply with IS/IEC 60079 standards, ATEX directives, and Indian regulatory requirements, ensuring your facility’s safety and regulatory adherence.
| Gas/Vapour Zone | Dust Zone | Description |
|---|---|---|
| Zone 0 | Zone 20 | Explosive atmosphere is present continuously, frequently, or for long periods. |
| Zone 1 | Zone 21 | Explosive atmosphere is likely to occur during normal operation. |
| Zone 2 | Zone 22 | Explosive atmosphere is not likely to occur during normal operation, but if it does occur, it will exist only for a short period under abnormal conditions. |
Standards We Follow
- IS/IEC 60079 Series (Explosive Atmospheres)
- ATEX Directives (2014/34/EU)
- Petroleum Rules and PESO guidelines
- NFPA and other relevant international standards
Why is Zone Classification Important?
- Prevents ignition sources in hazardous areas.
- Ensures the selection of appropriate electrical and mechanical equipment.
- Reduces fire and explosion risks.
- Supports compliance with statutory requirements and insurance conditions.
- Improves overall safety culture in hazardous environments.
Our Zone Classification Methodology
Step 1: Process Understanding
We study the processes, materials handled, and plant layout to identify potential hazards.
Step 2: Data Collection
Material safety data, ventilation data, and operational parameters are collected.
Step 3: Hazard Analysis
Evaluation of flammable material sources, leakage likelihood, and dilution.
Step 4: Classification of Zones
Zones are classified based on IEC/ATEX guidelines:
- Zone 0 / Zone 20: Continuous presence of explosive atmosphere.
- Zone 1 / Zone 21: Likely presence under normal operation.
- Zone 2 / Zone 22: Unlikely, but possible under abnormal conditions.
Step 5: Documentation & Drawings
We provide classified area drawings, detailed zone classification reports, and recommended control measures.
Step 6: Training & Advisory
We train your team on working safely in classified zones and equipment selection.

Factors That Decide Zone Classification Cost in India
Zone classification cost depends on: plant size and number of process areas, complexity of materials handled (gas, dust, or both), whether new classified-area drawings are needed from scratch or an existing classification is being reviewed, and site location.

Client Testimonial
EHS Officer, Specialty Chemicals Unit
“Good response from our team for the chemical spill drill and awareness session. We had a minor leak last year and this training was timely. They even explained the MSDS sheet details clearly.”
HR Coordinator, Shared Services Office
“Elion conducted ergonomics training for our office support staff. They gave tips that don’t need any budget—just posture, breaks, and seating angles. Everyone found it useful.”
Logistics Supervisor, FMCG Warehouse
“Warehouse safety training was organized at our distribution center. The module covered stacking, material flow, and emergency handling. One or two team leads found the content basic, but the newcomers appreciated it.”
Site Incharge, Metro Rail Project
“The hot work and gas cutting safety training helped us address some recent near-misses. Our fabrication contractors said it was the first time anyone explained why permits matter, not just how to fill them.”
HR Manager, Corporate Insurance Firm
“We held a training on ergonomics and workstation safety. Elion’s speaker had a practical approach—suggested small furniture changes and posture tips that didn’t cost much but helped our office staff.”
Plant Head, Frozen Foods Facility
“Elion covered cold storage safety and ammonia handling well. Some of our technicians said it was the first time they understood how to respond to leaks. We may request them for a follow-up drill.”
HR Officer, Apparel Manufacturing Unit
“Our garment unit required machine safety awareness for new joiners. Elion kept it interactive and used visuals from our own plant, which the workers related to.”
Operations Manager, Steel Trading Yard
“The crane and material handling training helped reduce near misses in our yard. The trainer also gave tips that were not in the slides, based on their field experience. That made a difference.”
Admin Manager, IT Park
“We requested a training module on emergency evacuation procedures. Elion included site-specific examples which helped. The mock drill later was well-coordinated too. Our fire wardens felt more confident after the session.”
