QR Code Implementation and Production Guide for "One Helmet, One Code" System at Sinohydro Bureau 4 Nila Power Plant
Original article: https://cli.im/article/detail/2330
Digital intelligence leads the way in safety empowerment. The power plant actively explores efficient and precise onsite safety management models, innovatively applying QR code technology as an onsite assistant. This initiative implements real-name verification requirements for worksite operations and enhances standardized management through QR codes.

At Nila Power Plant worksites, each employee has a dedicated safety helmet with a customized QR code. Scanning the code immediately displays the employee's basic information (name, job category, operational permissions, contact details), safety training records, certifications, and health status. The QR code dynamically updates safety technical briefings and training records. If corresponding records are missing, certifications incomplete, or health status suboptimal, workers will be denied worksite access.
The QR code-enabled helmet management system allows safety information to be carried, checked, and viewed anytime. It helps managers quickly verify worker qualifications, preventing potential safety hazards like unauthorized position changes. This system not only facilitates daily safety management but also eliminates inconveniences caused by wearing physical credentials during operations and maintenance.
Additionally, emergency contacts are embedded in QR codes to enable immediate incident reporting and handling. The next phase will achieve full "one helmet, one code" coverage for all teams, driving continuous improvement in worksite safety management through refined information systems.
QR Code Helmet Implementation Overview
To implement certified personnel verification while eliminating physical credential inconveniences, Sinohydro Bureau 4 Nila Power Plant uses CaoLiao QR codes to create personnel codes attached to safety helmets. These codes replace physical certificates and store employee information including:
