Mechanism Analysis and Prevention Method for Tunnel Fire

Abstract:

By analyzing the typical fire cases and tunnel fire statistics during 2008 to 2013 in Fujian province of China, results shows that the main causes for the fire were vehicle accidents and spontaneous combustion. By the investigation, there are three approaches to prevent the tunnel fire exposed to different combustibles. For flammable solid, an effective method to prevent fires is to decrease the maximum environment temperature and the product concentration. For flammable liquid, adjusting the ambient temperature and enhancing ventilation can prevent or reduce the fire accidents. For flammable gas, the effective method to prevent the fire is to decrease the fuel density and the ambient temperature. So, for long tunnels or busy tunnels, it must strengthen the management of the vehicles. Moreover, in the hot season and rush hour it should control the ambient temperature inside the tunnels.
