Fire Extinguishing in Complex Facilities – A Study of Large Fire Extinguishing

Abstract: This report analyzes fire extinguishing solutions that might cut time between fire alarm and fire extinguishing at the European Spallation Source. A special design fire with a very high peak heat release rate is used. The method used includes a literature study, meetings with supervisors and ESS representatives and participation in workshops and study visits. Some fire protection measures are already planned, but additional measures are investigated, namely automatic fire extinguishing systems and manual fire suppression. The conclusion of the report is that the time aspect is crucial and that combining different local automatic extinguishing systems with an on- site First Responder team might save crucial time. The team should be educated in firefighting, equipped with several fire suppression systems and have the possibility to use positive pressure ventilation. Also, some improvements for an intervention by the municipal fire brigade are presented.
