Tunnel vision: A new perspective


Reports on a research project in which the Hagerbach tunnel facility in Switzerland was used to study the effects of water mist on the heat, smoke and carbon dioxide produced in a tunnel fire. The aim was to establish clear guidelines for tunnel fire management in terms of making optimum use of ventilation and water mist with a view to minimising the dangers to human life. Presents and discusses the results. Concludes that water mist systems activated whether automatically, by linear heat cable or manually, can give persons involved in a fire valuable minutes in which to escape.
