Evaluation of Railway Tunnels Safety for Operation Involving Trains Carrying Dangerous Goods – Fire Hazard and Risk Assessment Implemented with Probabilistic Methods

Published: 12 April, 2010

There are several “magic numbers” available in fire engineering literature, determined on expert judgement or statistical data collected about experiments or real fires reports, which can be regarded as design values for a certain fire scenario, e.g. the curve and the peak value of the HRR arising from the fire of a car or a wood pallet, as other fundamental parameters characterizing a fire scenario [1].

The choice of a certain “reference scenario” among a class of possible fire scenarios, the lack of knowledge and the randomness about the phenomena involved, are different sources of uncertainty affecting the outputs of any quantitative fire threat assessment.
