Geofencing, IoT Wearables & Blockchain for Worker Safety (Looking for Insights )

Hi everyone, I’m working on a 3-week university project about safety methods in industrial environments using digital twins, IoT wearables, and blockchain. The idea is to track a worker in a high-risk area (accidents, dangerous zones, restricted access), collect sensor data, use geofencing to detect unsafe behavior, visualize everything in a digital twin, and store alerts or incidents on blockchain for traceability.

Has anyone here worked on something similar or has experience with IoT safety systems, geofencing, or digital twins in industrial contexts? Any advice or resources would be super helpful!
