Firefighting safety and efficiency in twin-tube city road tunnels

Abstract: Key question: Can firefighting tactics in twin-tube road traffic tunnels be made safer and more efficient through infrastructure design and installed equipment. Method: A literature study was conducted, and individuals in the Nordic countries with experience in the field were interviewed. All gathered knowledge was analyzed, and suggestions for solutions were brought forward. Results: They included how to use different parameters that affect firefighting tactics in the design phase to evaluate if the design provides an opportunity to perform rescue operations - providing valuable insights into the opportunity to increase firefighters safety and efficiency in twin-tube tunnels, with the potential to minimize the consequences in case of emergencies.
