SINA can handle and resolve all issues regarding safety in tunnels and the design of all necessary systems.

In accordance with European Directive 2006/54/CE, transposed with Italian Legislative Decree no. 264 of 5 October 2006, SINA took the opportunity to broaden its expertise, which spans from designing and planning improvement works to risk analysis, supporting operators in preparing emergency plans and defining technical and performance specifications for systems and technology installed.

Back in the ‘60s, SINA patented a longitudinal ventilation system installed in various tunnels on the national road network, and since 1975 it has offered methodologies and calculation methods for ventilation systems, which were later approved and adopted by the World Road Association (PIARC).
