Safety procedures

The teams use the latest equipment

The Tunnel teams use a computerized management tool, which collects and analyses 35,000 pieces of data to ensure safety. It allows automatic, rapid, and appropriate interventions based on the incident detected (lighting, ventilation, triggering help, etc.). The control station operators manage this system using monitors and a giant video wall.

3,860 sensors detect any rise in temperature: with the 3,860 thermal sensors distributed throughout the tunnel length, the detection system alerts the control centre to any abnormal rise in temperature.

157 cameras detect any incident inside the tunnel. These video-surveillance cameras are permanently connected to a system that analyses the images.They automatically and immediately detect anything abnormal: objects in the road, slowing down, stopped vehicles, etc. The goal: to alert and trigger appropriate safety procedures.

37 emergency exits, which are located every 300 meters and are clearly marked, enable your safety during an emergency in the Mont Blanc Tunnel while waiting for evacuation by specialized teams. These shelters, pressurized and supplied with fresh air to prevent smoke from entering, have two fire doors (2 hours of fire resistance). They are equipped with video phones that connect directly to an operator and allow you to access an underground evacuation tunnel. This is complemented by 36 emergency stop locations and 116 SOS stations allowing you to park and contact the Tunnel teams if necessary.
