Modem sensor technologies in conjunction with intelligent software make possible an objective evaluation of sensory perceptions and thus create the basis for equipment containing "sense organs". Systems responding to acoustic, thermal or optical stimulations have long since established themselves in industrial applications. Now the "Electronic Nose" has been developed according to principles of nature and is ready for industrial application. However, in comparison to the human model the Electronic Nose has highly enlarged capabilities. The human sense of smell is subject to external influences and can therefore provide only subjective odour structures. In addition there are gases, which the human nose cannot detect. The recognition of such substances, however, plays a special role in the assessment of situations and processes. This paper outlines the challenges involved in the design and implementation of an efficient and safe system for detection of fire incidents in tunnels. It furthermore outlines the possibilities of Multiple Gas Detection technology (MGD) as solution to improve safety in tunnels.
