The lorry fire that broke out on 26th July 2011 in the Brynglas Tunnel in South Wales caused severe traffic disruption for four days, and this has underscored the potential damage associated with tunnel fires. Could better design reduce the risks? The World Road Association (PIARC) will shortly be publishing a new report on design fires for tunnels, which will go some way towards clarifying how the tunnel fire risks can be assessed and managed. In particular, the report provides updated information on fire heat release rates and the timedevelopment of vehicle fires, based on experimental tests. However, for those seeking instant answers to design fires in tunnels, the report delivers some rather sobering conclusions: a universal design fire cannot be specified, because the probability and size of any fire is inherently unknown.
