Mission Safety

As a native of Toulouse, Charles Gris saw the first metro line being built as a child. He was later involved in the construction of the second line as a mechanic. When an opportunity arose in 2024 to continue his involvement in the expansion of the Toulouse metro at Implenia France, the decision was clear.

"Once you've worked in tunnel construction, this passion never lets you go. I am proud to be involved in such an iconic project in my city."

Charles Gris, Prevention and Environment Officer

Since then, he has been working on the Métro Toulouse project as a prevention and environment officer, coordinating safety inspections and visits from the labor inspectorate and ensuring compliance with safety regulations on the construction site. "I check that personal protective equipment is being worn correctly, that pedestrian routes are sufficiently safe and that collective protection devices are working properly," he explains. "All of this is to ensure that everyone involved can work under the best possible conditions."

In addition to these tasks, Charles is also a survival instructor, a key role in risk prevention in underground environments. "It's about educating everyone involved about possible risks so that they can react correctly in an emergency," he emphasizes.

In addition to specialist knowledge, his position requires above all human qualities: social skills, communication skills, awareness, adaptability and the ability to convince others of the importance of vigilance and compliance with regulations, especially in an environment as demanding as tunnelling.
