For oil and gas, chemical, pharmaceutical, food, and mining facilities, the same ignition triangle drives engineering: fuel, oxidant, and an effective ignition source under fault or normal operation.
This article highlights considerations for EMC Shielding Changes vs Ex Enclosure Integrity under compliance & audits 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.
Book a consultation with HazloLabs when markets or standards change mid-project—early alignment saves retest cycles.
