Zone Classification Services for Hazardous Areas

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.

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.
