Hazardous location compliance ties together area classification, equipment marking, installation practice, and traceable records across the equipment lifecycle.
This article highlights considerations for Class I Division 1 vs Division 2: Practical Differences under area classification themes. It is educational and not a substitute for project-specific standards, certificates, or AHJ rulings.
Documentation packages should include certificates, declarations, drawings, BOMs with manufacturer part numbers, and installation conditions of use.
Non-electrical equipment (e.g., pumps, gearboxes) falls under ATEX 2014/34/EU Category rules and machinery integration with ignition hazard assessment.
Cable glands, conduit seals, and enclosure entries are part of the certified assembly; torque, thread type, and compound fills must match certificate conditions.
Map your equipment EPL and type of protection to the classified area, then verify installation conditions of use, cable entries, grounding, and maintenance intervals. Keep declarations and certificates version-controlled.
