Journal article (peer-reviewed)abstract
- Recent catastrophic fires in road tunnels and a new confidence in water-spray and mist systems have had a profound effect on the use of fixed fire-fighting methods in tunnels. Closing the tunnel for a long time would cut revenue and alter the route users typically take. Life-safety issues are more important in dense-traffic urban tunnels, but also where there is a risk of queuing. In Sweden, for example, installation of a FFFS system solved a difficult discussion between fire-rescue services and the road administration concerning risks associated with queuing in both new and future tunnels located in densely populated areas. Experiments have been carried out both on liquid-pool fires in pans and on large and small vehicles, or vehicle mock-ups. In all cases, experiments have been conducted in tunnels that are longer than the Ofenegg tunnel, with greater cross-sectional areas and with totally different ventilation conditions.
