✓ Ensure the safety of workers descending into the underground
✓ To respond in a simple way to regulatory constraints
✓ Take into account the technical constraints: low temperatures (-30°C), shock resistance and high humidity
Each worker is equipped with a PUCK ID. At the entrance of the well, an antenna is installed to pick up the tag attached to the helmet of each worker, which will ensure that the worker has entered the well. Once the worker goes down into the well, another antenna located in the well will pick up the tag again to ensure that the worker has gone down.
At the same time, a tag checker has been installed, which allows to check the correct functioning of the PUCK ID before the descent in the well. If the LED of the tag checker is green, the PUCK ID is working, so the worker can descend.
If the LED is red, it means that the PUCK ID has a malfunction, so it must be changed in order to properly equip the worker and ensure his safety.
This parallel solution allows to secure the identification solution.
✓ Reliability of personnel counting
✓ Safety in case of incident
✓ Better control of access to the shaft
✓ Simplicity in the verification by the team that no isolated worker is in the tunnel
