Based on an assessment of the tunnel safety in terms of the four elements - fire, air water and earth - some principal aspects regarding tunnel safety have been established. With respect to tunnel equipment, it appears that rapid fire detection and the subsequent swift tunnel closure for incoming traffic is a main element. In case of fire, it should be expected that active information of tunnel users is required and for this purpose the loudspeakers of the type SLASS are to be considered. The emergency exists need to be attractive to use and should distinguish themselves from the service doors. In case of unidirectional traffic that is never congested, longitudinal ventilation is appropriate for smoke management. Otherwise, smoke extraction is more favourable. Fixed fire fighting systems can be installed to reduce the impact of tunnel fires on the tunnel structure and in order to increase the level o f safety for the tunnel users.
