L’incendio nel tunnel del Monte Bianco, ove persero la vita 39 persone, è stato il più grave nella storia dei tunnel transalpini. Tale evento disastroso ha spinto, negli anni successivi, a compiere migliorie nel settore della sicurezza antincendio nelle gallerie, ponendo molta attenzione agli aspetti di prevenzione, definendo criteri di progettazione innovativi e metodologie gestionali più efficaci. Lo scopo di questo articolo è quello di esporre delle fasi metodologiche di Fire Investigation atte ad individuare le cause scatenanti, pregresse e latenti, che hanno determinato tale evento accidentale. L’illustrazione di questa attività investigativa rappresenta un caso applicativo di quanto esposto nell’articolo Structural Fire Investigation e ingegneria forense. L’iter investigativo associato a determinate operazioni, in parte codificate, svolte anche attraverso l’ausilio di indagini computazionali (computational investigation), può aiutare a determinare nel dettaglio le cause e migliorare il livello di sicurezza antincendio di tali strutture.Le indagini svolte hanno messo in evidenza i difetti meccanici dell’automezzo e le carenze nella gestione dell’emergenza. Non si tratta dunque di uno scenario imprevedibile (black swans) ma di uno scenario probabile.

Abstract
The Mont Blanc tunnel fire was the most severe in the history of the trans-Alpine tunnels, where 39 people lost their lives. This disastrous event, which took two days of action, prompted, in subsequent years, to make improvements in the field of fire safety in tunnels, paying attention to the aspects of prevention and leading to the definition of design criteria and more effective innovative management methods. The purpose of this article is to expose the various methodological steps of Fire Investigation aimed at identifying all the causes, past and latent, which determined that accidental event. The illustration of this investigative activity in a case of application of the above article Structural Fire Investigation and forensic engineering. The investigative process associated with certain transactions, codified in part, carried out through the use of computational investigations, can help determine in detail the causes and improve the level of fire safety of such structures. The investigations have shown mechanical defects of the vehicle and deficiencies in emergency management. An unpredictable scenario (black swans) is out of question, as it is a very possible scenario.File | Dimensione | Formato | |
