The SWT (Safety Working in the Tranchees) project consists of setting up technical training on the securing of trenches during the installation of buried networks. The aim of the project is to provide employees in the construction sector with skills in the field and to be made aware of the risks inherent in this type of work.Several specific training courses are planned as light shielding, heavy shielding and safety during trench work. Different virtual immersion type experiments will also be developed as part of this project.This project is also part of the national campaign “Vision Zero” which aims to reduce occupational risks in the workplace.
