Nordic Fire & Safety Days 2018

7 juni 2018

The Nordic Fire & Safety Days 2018, the largest conference on Fire and Safety in the Nordic countries, is this year on June 7th-8th hosted by NTNU Trondheim in Norway. NFSD is an annual event carried out by the Nordic universities and research institutes involved in risk and fire safety. The conference is held by RISE Research Institutes of Sweden, RISE Fire research Norway, in collaboration with the Technical University of Denmark, Lund University, Aalto University, Luleå University, Norwegian University of Science and Technology, University of Stavanger University College Haugesund and Iceland University as well as VTT Technical Research Centre of Finland  Ltd and the Danish Institute of Fire and Security Technology. The days put focus on risk and fire research in the Nordic countries.

One topic to be raised at this year’s conference is the pressure rise in modern buildings on fire, possibly leading to devastating situations. This is a topic, which has been introduced by the research community at the NFSD 2017 thereafter lifted by fire fighters at a workshop in Borås in January 2018. It results now in the key note lecture by professor Simo Hostikka, Aalto university, Finland at the coming Nordic Fire & Safety Days (NFSD) in Trondheim in June 7th and 8th 2018.  It deals with the occurrence of overpressure in burning apartments, which, depending on the orientation of the door, has prevented evacuation from apartments and hindered the fire brigades entrance into the site. Pressure peaks close to 1500 pa after 1 min have been observed. A major objective for the NFSD is to formulate important common areas for Nordic fire research and it seems clear that “Modern Building Fires” fits very neatly into this.

Another discussion at the conference will be the occupational safety on wind turbines, a workplace for around 500 000 technicians in Europe. The fire safety of turbines has been studied in a RISE project. The passive fire safety f.eg. the materials used to construct the turbine generally follow the requirements for buildings, as turbines are machines not buildings. Some safety aspects such as specific requirements apply with respect to evacuation and occupational safety. The work presented at the NFSD 2018 by RISE and the Technical University of Denmark, is a study on the ropes used to descend the tower, which usually takes several minutes. The study showed, the melting temperature for the rope used in the experiment was around 250°C and ignition occurred at temperatures, which are seen during a fully developed fires. More studies are needed to ensure the occupational safety on wind turbines.
