Eurotunnel awarded a contact in November last year to a consortium of RodioJ, Fogtec, ACIS, Eiffage, and Spie to develop the system. The test was performed in temperatures high enough to reach and even exceed 100 and 150MW, which equates to a fire involving 40 automobiles.
"A system such as this aids in the evacuation of people and enables the rescue services to work with increased speed and safety," says Mr Dirk Sprakel, managing director of Fogtec. "Due to the ability to control the fire and the minimal amount of water used, structural damage is considerably reduced."
Each fire-fighting station will be around 870m long and will be equipped with a heat detection system. Once the train has stopped, a mist of water will be vaporised in the section where the fire started to create a shower of micro-droplets which absorb the oxygen and heat when they come into contact with the fire. This suffocates the fire, preventing it from reaching temperatures above which the infrastructure in the immediate area starts to sustain damage.
Eurotunnel has suffered two major fires in the Channel Tunnel, both causing serious damage to the infrastructure and major disruption to services. The new fire-fighting stations will complete a range of measures being introduced by Eurotunnel to reduce the risk of fire.
