Hazardous location compliance ties together area classification, equipment marking, installation practice, and traceable records across the equipment lifecycle.
This article highlights considerations for Competency for Inspection per IEC 60079-17 under maintenance programs themes. It is educational and not a substitute for project-specific standards, certificates, or AHJ rulings.
UKCA marking for explosive atmospheres replaced EU CE for Great Britain; technical requirements often track ATEX but conformity routes differ.
Gas groups (IIA, IIB, IIC) and dust groups (IIIA, IIIB, IIIC) constrain equipment selection; mismatched groups are a frequent cause of project rework.
IEC 60079-0 establishes general construction and testing requirements; part-specific standards (60079-1, 60079-7, 60079-11, etc.) add detailed rules for each type of protection.
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.
