A tunnel is one of the most complex building in construction and maintenance. Generally, they are used to ease transit and reduce travel times. The available safety concepts are shared according to national frameworks between firefighters, technical relief organizations and armed. They is no common concept in firefighting in tunnels between these organisations and between the European members states. Professional exchange should be mandatory but it is spare and unstructured. SAFEINTUNNELS will close a knowledge and action gap for firefighters and victims by:• Firstly, firefighting in tunnels are highly customized strategies reflecting local and/or regional conditions (place, type and age of tunnel, rescue scheme applied etc.) on the one hand, but on the other hand, it has common nominators that can and should be shared. EU-Platforms for this purpose are neither available nor established – difficult to believe.• Secondly, for firefighting in tunnels the technical devices are often derivations of other complex devices in firefighting; their range of applications are extremely broad and will increase even further with the Trans-European transport network and the growing urbanization across Europe– e.g. the reciprocal dependence of tunnels and bridges orchestrating the different types of traffic through the Alps.• Thirdly, devices for firefighting in tunnels are designed to rescue the affected people and safeguard firefighters in this special state of emergencies, under substantial time constraints and in situations with unknown or unforeseen variables. Therefore, the firefighters usually use the most expensive devices in the fleet of vehicles and rescue trains for firefighting (most of which are funded by taxpayers).The scheme will be further developed to allow vocational training and education of Vet teachers and comply with the ECVET-standard. It shall be applicable and adaptable to all tunnels in use independent of the year of construction.
