Earth Continuity — Inspection Requirements for Ex Equipment
This article covers Earth Continuity — Inspection Requirements for Ex Equipment. Effective earthing is required for all Ex equipment. This guide covers earth continuity inspection requirements, common earthing deficiencies, and how to classify earth-related issues under IEC 60079-17.
Key Requirements
This inspection topic is covered in depth in IEC 60079-17 and tested in CompEx Ex03 and Ex04 assessments. Understanding the correct approach to this inspection scenario is essential for safe hazardous area inspection practice.
EX Academy's 15 inspection simulations cover this and related inspection scenarios. Each simulation presents a real work order, equipment data, and inspection findings that require deficiency identification and classification — exactly as you will face in your CompEx assessment.
Classification Guide
When assessing this type of deficiency, always apply the fundamental question: does it compromise the protection mechanism? Use the Category X/A/B/C framework from IEC 60079-17 to make your classification decision and document your findings clearly.
