Tehnomobil&LIOS Technology ’s new standard for fire safety solutions in Croatian tunnel network

Tunnels are sensitive traffic bottlenecks and consequently extraordinary vulnerable in case of accidents or fire blasts. Danger for life and enormous economic consequences ask also for technical solutions of prevention and limitation of damage. Tehnomobil and

their partner LIOS Technology have set a new standard for modern fire safety solutions for the road tunnel network in Croatia.  Tehnomobil’s excellent engineering and contracting background in traffic infrastructure and fire fighting industries perfectly match with LIOS Technology’s comprehensive experience in fire detection applications for tunnels and special hazard buildings with an impressive track record of more than 2000 installed fibre optic temperature sensing systems worldwide.

Best fire surveillance for more than 90 % of the road tunnels in Croatia

At present an impressive share of more than 90 % of the Croatian road tunnels Tehnomobil have equipped with the fibre optic fire detection system by LIOS Technology. In 28 tunnels with in total 55 tunnel tubes the purely passive LIOS fibre optic line sensor cable has been installed by Tehnomobil for reliable and fast fire detection. Those tunnels with tube lengths ranging from 500m to almost 6000m were newly opened in recent years or re-opened after full refurbishments where the conventional line type fire detection system could be replaced by the fibre optic LIOS system.

EuroTAP: Brinje Tunnel on Dalmatina highway tops Europe’s safety ranking

The European Tunnel Assessment programme (EuroTAP) place a Croatian tunnel, the “Brinje” at the top of the list, as the best tunnel in Europe in 2007. EuroTAP 2007 inspected 51 major road tunnels important for transeuropean road traffic located in 13 countries across Europe and concluded that none could beat this Croatian tunnel despite the fact the since 2004 tunnels in the European Union must comply with a Directive prescribing minimum safety standards for road tunnels . The Brinje, a 1570m tunnel opened in 2004, located on the A1 between the cities of Zagreb and Split displayed top scores for the fire protection and winning features in all safety categories:

• low risk traffic flows using two tubes,

• 24 hour monitoring from a tunnel control centre manned by trained staff,

• immediate notification of traffic disruptions,

• use of lay-bys or emergency facilities,

• additional escape and rescue routes well marked by evacuation lighting and

• good indications of the escape direction & the distance to the nearest exit.
