The tunnels have smoke removal fans, which are switched on rescue personnel manager arriving at the scene in case of accident. There are also evacuation routes for people, which have illuminated markings and lead people out of one structure to the other and then out of the tunnel.
Tunnelites on suitsueemaldusventilaatorid, mis käivitatakse õnnetuse korral kohale saabunud päästetööde juhi poolt, samuti on inimestele loodud evakuatsiooniteed, mis on tähistatud valgustitega ja juhivad inimesed ühest kehandist teise ning tunnelist välja.
