USE OF WATER BASED FIXED FIRE SUPPRESSION SYSTEMS IN URBAN ROAD TUNNEL FIRE PROTECTION
Urban road tunnels are critical components of the transportation systems in the city around the world. Ensuring fire safety in urban road tunnels is more challenging than ever due to the specific features of the tunnels, increased traffic and inadequate safety rules. Fixed fire suppression systems are used as an effective fire protection measure in the built environment. But, many countries have not considered them necessary or even acceptable for tunnel protection. However, with a significant increase in the number and the scale of fire accidents in tunnels around the world, there is renewed interest in the use of fixed fire suppression systems for tunnel protection. This paper firstly reviewed current activities into use of water based fixed fire fighting system in the urban road tunnel. The concern is focused on the use of these systems in tunnel environments, such as the visibility reduction during evacuation caused by water discharge, their performance in suppressing shielded fires, potential hazards presented by hot steam and deflagration generated in suppressing large flammable fuel fires. Comparisons of these systems will then be drawn to get full knowledge on the most suitable suppression systems for tunnel protection. The challenges associated with the use of these systems in tunnel applications will also be identified.
