Maxisimising tunnel conectivity and sefety
Creating a protected safety zone and escape corridor for tunnel by-passes
Zitrón has developed the MODULBYP unit to provide a protected safety zone and escape corridor for transport tunnels. Each unit contains connections with the tunnel’s electricity supply grid and data network, thereby enhancing safety measures and rapid communication with support services.
The unit has been designed to comply with all national and European Union regulations and directives for tunnel safety, which stipulate the need for pedestrian cross-connections and entryways with a maximum separation of 300 metres between the two channels of a tunnel.
The cross-connections between the two channels of the tunnel are aimed at providing a guaranteed escape route to the outside and the possibility, where space permits, of a temporary shelter for the safety of users in the event of a fire.
