Tunnel Safety
Fire Modelling and Fire Detection By Dr. Claudia Rexfort, Development and Organisation in Fire Safety, VdS Schadenverhutung GmbH Smoke detection is a common method for an early notification of fires. This article focuses on the smoke detection and the simulation of the process of smoke detection.
Fire Safety in Tunnels During Construction By Prof. Haukur Ingason and Dr. Anders Lunnermark, SP Technical Research Institute of Sweden, Dr. Hakan Frantzich, Lund University and Maria Kumm, Malardalen University. Several fires have already occurred at tunnel construction sites, causing death or injuries to individuals and losses and damage to equipment and the structure of the tunnel itself.
Tunnel Vision - Modern Surveillance Systems are Helping to Improve Safety in Tunnels By Ad Biemans, Product Marketing Manager, Bosch Security Systems Video surveillance of road tunnels reveals increased incidents of reckless driving within tunnels, including more incidents of dangerous overtaking, lane switching, speeding and driving in prohibited lanes.
By Ian Buchanan, European Manager, Spectrex Inc. Detecting various fire scenarios in road and rail tunnels is a complicated task that requires fast and reliable fire detection systems.
Numerical Simulations of Fire Scenarios in Tunnel - Fire Protection Strategies By Giovanni Manzini, Flavio Parozzi, SSG – Nuclear Power Plants and Safety, ERSE S.p.A. and Luca Iannantuoni, Department of Energy - Politecnico di Milano The aim of these simulations was to estimate the effectiveness of different fire-fighting strategies and to mitigate the consequences of fires with a focus mainly on the smoke propagation and air temperature mitigation.
Emergency Ventilation Strategies in a Roadway Tunnel By Dr. Ahmed Kashef, Senior Research Officer, Fire Research Program, National Research Council of Canada Assessing the ability of in-place emergency ventilation strategies to control smoke spread and minimize its impact on tunnel users using both numerical and experimental approaches.
Tunnel Ventilation Effectiveness in Fire Scenarios By Francesco Colella, Dr. Guillermo Rein, Dr. Ricky Carvel and Prof. Jose L. Torero, University of Edinburgh The developed model has been adopted to conduct a comprehensive study of the ventilation system in several tunnels including the 1.5 km long Dartford tunnels (near London, UK).
Fire Detection in Tunnels - An Actual Overview on Technologies and Systems By Dr. Arnd Rogner, CEO, Metaphysics S.A. Linear type heat detectors have been used as the most important technology before, today new technologies as smoke detection, video and others have been coming up or are under investigation.
Introducing A New Era of Underground Safety: Water Mist in Tunnels By Markku Vuorisalo, Tunnel Fire Protection Manager, Marioff Corporation Experience drawn from fire testing and field installations shows that high-pressure water mist technology is an excellent solution for preventing direct and consequential damage to people, tunnel infrastructure and traffic.
Sustainable Tunnel Safety in Increasingly Converging Transport Networks By Urs A. Rufener, Tunnels Within the Fire Safety Applications & Offering Team, Siemens Building Technologies The need to build more and longer tunnels is set to continue to grow in order to cope with increasing road and rail traffic and the need to connect ever more sprawling suburbs to city centers.
Optical Fiber Distributed Temperature Sensing System for Road Tunnel Protection By Dr. Zhigang Liu, General Fire Technologies, Inc., Hidehiko Komeda, Hidenori Higashi, J-Power Systems Corp. and Toshiyuki Furuhashi, Smitomo Electronic The optical fiber DTS system, based on Raman scattering, is a popular fire detection technology with unique advantages used in road tunnel protection.
Passive Fire Protection in Tunnels - The Costs of History Repeating Itself By Wilf Butcher, CEO, Association for Specialist Fire Protection (ASFP) Passive fire protection measures are used in most modern construction, determined by an assessment of the risk to those working, living or travelling within the environment.
