Inspection relied on paper sheets with missed checks hard to detect, gauge readings copied afterwards, invisible personnel locations, and separate intercom devices.

Certified explosion-proof handhelds were used in intrinsically safe zones with NFC checkpoint tagging, on-site gauge entry and photo evidence.

Inspection trajectories returned to the monitoring platform in real time with full personnel visibility; built-in intercom covered all inspection communication.

Inspection completion and anomaly detection rates improved significantly, records became assessable electronic data, personnel were fully visible, and device burden was reduced.
