THE SEVERITY OF HGV FIRES IN TUNNELS
To date, only one experimental fire test of a heavy goods vehicle (HGV) in a tunnel has been carried out. This fire test was not typical of real HGV fires in tunnels for a number of reasons. A new fire model has been developed to estimate the size of HGV fires in tunnels. Based on the results of three different research projects, this model predicts the probability distribution of maximum fire size for a HGV fire in a tunnel, subject to longitudinal ventilation, and also the probability of this fire spreading to an adjacent HGV. The preliminary version of the model, CERBERUS A1.1, is briefly described. Results are presented for a number of different longitudinal ventilation velocities, vehicle separation distances and cargo types. The trends observed in these results and their implications for life safety are discussed. Development of the model is ongoing, the intended future capabilities of the model are briefly discussed.
