Road Administration has made changes

the reason that the system worked as it did in Gudvanga Tunnel in 2015 is that the fire brigade GUIDES others: fast possible to the city and to have fresh air in the back. Regional Manager in the NPRA, Helge Eidsnes, say that they no looking at approaches to whether the automatic steering arm.

– We have actually changed on these routines. In new tunnels are the completely different governance ways, where ventilation not automatically reversed. We look at how ancient tunnels can be upgraded, that will look for the system. We ein løpande dialogue with the fire department to put in place the best possible measures in each tunnel, victory Eidsnes.

If so, then fekk fire brigade criticism that they controlled ventilation in the direction where it was most people and cars to satisfy inside the tunnel. AIBN pointed also to bad information to dei trapped, poor communication and facilitation to salvage out of the tunnel. Mellum says that the situation is anything better this a time.

– road users came better out and ein losing in and turned the ventilation after an assessment, and it is EiT big strides, and ein right tactics that should be further developed.

  • Public Roads Administration should establish opportunities for and recommend enrollment check before innkøyring to expose tunnels.
  • NPRA should review and improve the equipment and routines by fires in tunnels. It should also be developed technology that ensures real-time information and instructions for Road Traffic Management Centre that ensures immediate notification of road users in case of fire.
  • The Road Traffic Centers Lane should tie to naud online tunnels.
  • DSB should further develop how the fire department’s efforts and smoke control can best support the self-rescue principle for tunnel fire.
