Area Classification

What Will You Learn?

• The Concept of Area Classification
• Understand why industrial sites are divided into zones to manage risks of fire and explosion.
• Zone Definitions
• Learn the differences between Zone 0, 1, 2 (gas/vapor) and Zone 20, 21, 22 (dust), including how often explosive atmospheres are expected in each.
• Practical Examples
• See real-world cases like tanks, silos, conveyors, and ventilation systems where these zones apply.
• Safety Standards & Regulations
• Explore international frameworks such as IEC/ATEX (Europe) and NEC Division system (North America).
• Equipment Selection
• Discover how electrical and mechanical devices must be certified for use in specific zones to prevent ignition.
• Risk Management Practices

Material Includes

• Video Lectures
• Clear explanations of concepts like Zone 0/1/2 and Zone 20/21/22, with animations showing real-world industrial layouts.
• Downloadable Course Notes & Handouts
• Concise summaries of standards (IEC/ATEX, NEC Divisions), definitions, and key safety measures.
• Case Studies
• Real examples from oil & gas, chemical plants, and food processing industries to illustrate classification in practice.
• Interactive Diagrams & Zone Maps
• Visual aids showing how hazardous zones are laid out in facilities.
• Quizzes & Practice Tests
• Multiple-choice questions to reinforce learning and check understanding.
• Checklists & Templates
• Ready-to-use tools for risk assessment, zone classification, and compliance audits.
• Reference Standards
• Extracts and guidance from IEC, ATEX, and NEC documents for deeper study.
