Protection des tunnels contre les incendies

Abstract : The project’s main goal is not to introduce a new fire suppression system but in fact to describe and analyze two common systems used worldwide, the FM-200 and Water Mist. The FM-200 system is used for specific rooms where fire fighting methods using water are prohibited, to avoid damaging delicate and expensive equipment installed in these rooms. This system has many advantages but it also has its disadvantages. For instance, a detailed study must be done in order to specify the exact FM-200 concentration needed, and the staff evacuation time from the protected rooms before discharge. The Water Mist high pressure system is mainly used in tunnels. This system uses high pressured water (from 80 to 140 bars) to extinguish fires while using a relatively small amount of water. This system is very effective as the water is not discharged directly into the equipments, and of course is not harmful to people. The water compressed at high pressure would put out a fire in a minimum amount of time, without using a large volume of water. The only disadvantage of this system is financial as the pumps required are very expensive. These two systems are only examples from countless Fire Suppression methods in use worldwide. In this report, the two systems introduced above (and all their required equipments) will be explained in detail while being studied in existing projects.
