    Brannsikkerhet i bygg med massivtre2017Report (Other academic)
    Abstract [no]

    I dette prosjektet er det gjennomført et litteraturstudie på brannsikkerhet ved bruk av massivtre i bygninger.   Problemstillingene det ble jobbet med var temperaturforløp i en naturlig brann, selvslokking og forkullingshastighet. Ut fra litteraturstudiet konkluderer vi med at kunnskapen om brannsikkerhet i forbindelse med massivtre i bygninger er mangelfull.  Det er spesielt rundt problemstillinger knyttet til ubeskyttet massivtre, forkullingshastigheter, delaminering og selvslokking det er flere ubesvarte spørsmål, og dette er forhold som kan ha stor innvirkning på brannsikkerheten i bygninger.   Vi anbefaler at det utarbeides retningslinjer for hvordan anvendelse av massivtre skal håndteres i prosjektering og risikoanalyse for nye bygg

    The effect of fire retardants on smouldering fires in loose fill wood fibre building insulation2017Conference paper (Other academic)
    Abstract [en]

    Building insulation products produced from renewable biomass is becoming increasingly common in buildings due to environmental lifecycle requirements. Biomass insulation products are combustible and can contribute to fires through flaming and smouldering combustion. Incidents have been reported where insufficient spacing between combustible insulation and heat-producing electrical appliances has led to smouldering and subsequent development of flaming fires. Insulation materials often contain fire retardants, though their performance with regard to smouldering fire is not well understood. [1, 2] This study investigates the temperature exposure needed to initiate self-sustaining smouldering fires in loose fill wood fibre building insulation, focusing on the effect of fire retardant content and fibre size. The study is a part of the EMRIS (Emerging Risks from Smoldering Fires) project. The test set-up is shown in Fig 1a [3]. The tested material was 100 grams, 34 kg/m3 spruce wood fibre loose-fill insulation with 4 and 9 % added ammonium polyphosphate fire retardant. Tests with short, fine fibres (Fig 1b) were compared to testst with long, thin fibres. The sample was heated from below until a given temperature was obtained 20 mm above the heater. Temperature and mass loss measurements as well as visual observations of the residue after test (Fig 1c) were used to characterize the onset of self-sustained smouldering. An iterative process was used, with 5 to 8 tests per product. It was found that a high level (9 %) of fire retardant gave an onset of smoldering at lower temperatures (225 °C) compared to a low level (4 %) of fire retardant (290 °C). The lower onset temperature indicates that the insulation with the highest fire retardant content is more prone to smouldering, which is contradictory to the expected performance of the fire retardant. For the same fire retardant content, the onset of self-sustained smouldering combustion was obtained at lower temperatures in insulation materials with smaller fiber sizes than in insulation with larger fiber size (225 vs 280 °C). This study is indicative, the absolute temperatures relate to the given test set-up. Further studies should include a range of fire retardant types and content, to obtain knowledge on their effect on smouldering fires.

    Extinguishing smoldering fires in wood pellets through cooling2017Conference paper (Other academic)
    Abstract [en]

    Extinguishing smoldering fires is a severe challenge for fire brigades, and has proven to be difficult even on the lab scale. In this study, the influence of a closed water cooling loop located within the fuel bed was investigated experimentally. Increasing the cooling led to a system less prone to intense combustion at an early stage, and eventually to complete extinguishment of self-sustained smoldering fires. Extinguishment was obtained in half of the cases with maximum cooling. Extinguishment occurred soon after smoldering had been established, giving a significant reduction in fuel consumption compared to the self-sustained smoldering fires that continued to complete burn-out.

    Smoldering combustion- from pulsations to extinguishment2017Conference paper (Other academic)
    Abstract [en]

    Smoldering is known as a slow, but unpredictable form of combustion. In this study we have looked at how smoldering is affected by water cooling of the fuel bed without direct contact between fuel and water flow. The study is a part of the EMRIS project, and its findings have possible implications for preventing and suppressing fires in industrial storage units.

    Extinguishing Smoldering Fires in Wood Pellets with Water Cooling: An Experimental Study2019In: Fire technology, ISSN 0015-2684, E-ISSN 1572-8099, Vol. 25, no 1, p. 257-284Article in journal (Refereed)
    Abstract [en]

    Smoldering fires in stored or transported solid biofuels are very difficult to extinguish. The current study has explored heat extraction from the combustion zone as a method for extinguishing such flameless fires. Heat extraction from the sample was made feasible using water flowing through a metal pipe located inside the sample. The fuel container was a steel cylinder with insulated side walls, open at the top and heated from below. Wood pellets (1.25 kg, 1.8 l) was used as fuel. Results from small-scale experiments provide proof-of-concept of cooling as a new extinguishing method for smoldering fires. During self-sustained smoldering with heat production in the range 0 W to 60 W, the heat loss to the cooling unit was in the range 5 W to 20 W. There were only marginal differences between non-extinguished and extinguished cases. Up-scaling is discussed, cooling could be feasible for preventing smoldering fires in silos.

    Analyse av dødsbranner i Norge i perioden 2005 - 20142017Report (Other academic)
    Abstract [no]

    I denne studien er informasjon fra brannstatistikk og andre kilder fra perioden 2005 – 2014 analysert, for å få mer detaljert kunnskap om hvem som omkommer i brann og hvorfor de omkommer. Dermed kan tiltak iverksettes mer målrettet for å redusere antall omkomne.  Følgende spørsmål er forsøkt besvart i studien: 1. Hvilke risikofaktorer forbindes med de som omkommer i branner i Norge? 2. Hva er årsakene til dødsbranner i Norge? 3. Hvordan kan dødsbranner best forebygges?  I den aktuelle perioden er det registrert 517 branner med 571 omkomne. Vi har kartlagt informasjon fra 347 politirapporter, identifisert 387 omkomne og trukket ut informasjon fra pasientjournalene til 248 av de omkomne.

    Analysis of 985 fire incidents related to oil- and gas production on the Norwegian shelf2018In: Safety and Reliability: Safe Societies in a Changing World / [ed] Stein Haugen, Anne Barros, Coen van Gulijk, Trond Kongsvik, Jan Erik Vinnem, 2018, Vol. 1, p. 1847-1854Conference paper (Refereed)
    Abstract [en]

    Fire is a major threat in the petroleum industry. However, little has been published about the fire related incidents that have occurred in the Norwegian petroleum sector. To gain more knowledge, data from 985 incidents in the 1997 - 2014 period has been analysed. Examples of factors studied are type of facility involved, involved area or system, consequences and severity level. The analysis of the fire incidents reveals that even though many incidents are reported, the large majority of these have not imposed risks for severe fire accidents. It has also provided valuable information regarding possible dangerous situations, commonly in-volved areas, types of equipment as well as types of activity that were involved. Twenty-nine percent of the incidents were false alarms, which must be regarded as a high number in an industry where any production stop could be extremely costly.

    Analysis of fatal fires in Norway in the 2005 – 2014 period2017Report (Other academic)
    Abstract [en]

    In this study, information from fire statistics and other sources has been analyzed to get more detailed knowledge than before about who dies in fires and why. This will help to implement more targeted measures in order to reduce the number of people perishing in fires.  The study attempted to answer the following questions: 1. What risk factors are associated with those who perish in fires in Norway? 2. What are the causes of fatal fires in Norway? 3. How can fatal fires best be prevented?  A total of 517 fires with 571 fatalities are registered in the official fire statistics in the 2005 – 2014 period. We have examined 347 police investigation reports, identified 387 deceased and  extracted information from 248 medical records.

    Abstract [en]

    Five-hundred-and-seventy-one fatalities were registered in the official fire statistics in Norway between 2005–2014. However, little is known about the victims. This study collected information from several sources to build a holistic database and gain more knowledge about the technical and social aspects of the incidents, forming a basis for more targeted measures. Human behaviour greatly affects the risk of fire, which supports why social aspects of incidents should be considered when identifying risk factors associated with the victims. The results showed a clear distinction between victims above and below the age of 67 with respect to risk factors. For the elderly, reduced mobility, impaired cognitive ability, mental disorders and smoking were observed risk factors. For the younger victims known substance abuse, mental illness, alcoholic influence and smoking were observed, mostly in combination. This shows that fire is a social problem, and should be prevented by initiating customised measures

    Utredning - branntekniske ytelser for kledninger og overflater2018Report (Other academic)
    Abstract [en]

    The Norwegian Building Authority (DiBK) has asked RISE Fire Research to review the preaccepted fire performances for coverings and linings in the guidelines to the Norwegian building regulations. Requirements for both interior and exterior coverings and surfaces(façades) have been evaluated.

    The review is based on a study of previous and existing Norwegian building regulations, and in addition, we have also examined how the classes for coverings and linings are applied and interpreted in the Swedish and Danish building regulations.

    Today's pre-accepted fire performance, class B-s3, d0, for exterior cladding including a cavityon facades is evaluated, based on the British investigations after the fire in Grenfell Tower inLondon in June 2017. A simple assessment of how the façade systems that were tested according to the British standard BS 8414-1 probably would behave if tested according to the method SP FIRE 105.The report concludes with several recommendations on revision of the text in the guidelines to the building regulations TEK17 intended to prevent misunderstandings regarding the fire regulations for coverings and linings.

    Smouldering Combustion inLoose-Fill Wood Fibre Thermal Insulation: An Experimental Study2018In: Fire technology, ISSN 0015-2684, E-ISSN 1572-8099, Vol. 54, no 6, p. 1585-1608Article in journal (Refereed)
    Abstract [en]

    A bench-scale experimental setup has been used to study the conditions necessary

    for smouldering ignition in four types of loose-fill wood fibre thermal insulation, and

    to study the development of the smouldering process. The products varied with regard to

    wood species, grain size and fire retardant chemical additives. The test material was

    placed in an insulated open top container and heated from below. Temperatures within

    the sample and mass loss were measured during the tests. Both the fibre size and the level

    of added fire retardant seem to influence the smouldering ignition. Two different types of

    smouldering were identified in this study. Materials undergoing smouldering Type 1

    obtained maximum temperatures in the range 380C to 440C and a total mass loss of

    40 wt% to 50 wt%. Materials undergoing smouldering Type 2 obtained maximum temperatures

    in the range 660C to 700C and a total mass loss of 80 wt% to 90 wt%. This

    implies that Type 2 smouldering involves secondary char oxidation, which represents a

    risk for transition to flaming combustion and thereby a considerable fire hazard. This has

    been an exploratory project and the results must therefore be considered as indicative.

    The findings may, however, have implications for fire safety in the practical use of loosefill

    wood fibre insulation in buildings, and further experimental studies should be performed

    with this in mind to obtain more knowledge about the topic.

    Metode for evaluering av branner2015Report (Other academic)
    Abstract [no]

    Denne rapporten beskriver en enkel metode som kan anvendes ved mindre omfattende evalueringer av branner. Med metode menes her en systematikk for gjennomføring av evalueringer. En mindre omfattende evaluering vil være en gjennomgang der det enten er få forhold ved brannen som skal undersøkes, eller der situasjonen er relativt oversiktlig. Metoden er deretter anvendt på en brann i et sykehjem. Evalueringen av denne hendelsen er ikke fullstendig gjennomført, men fungerer som et eksempel på hvordan metoden kan brukes.

    Rett tiltak på rett sted: Forebyggende og målrettede tekniske og organisatoriske tiltak mot dødsbranner i risikogrupper2015Report (Other academic)
    Abstract [no]

    Personer som på ulike måter kan kategoriseres som sårbare, er overrepresentert i dødsbrannstatistikken. Derfor er det viktig å finne fram til effektive og målrettede tiltak som kan forhindre framtidige dødsbranner der personer som tilhører det som omtales som sårbare grupper er involvert. I rapporten brukes en helhetlig analytisk tilnærming som skal fange opp mangfoldet av dimensjoner som kan påvirke forebygging av dødsbrann, og hvordan disse virker i samspill med hverandre. Prosjektet har operert med en forståelse av sårbarhet som inkluderer både det fysiske miljøet, de menneskelige behovene og de sosiale og organisatoriske omgivelsene. En del av rapporten retter seg mot tekniske løsninger som kan brukes for å forbedre brannsikkerheten til sårbare grupper. Det har vært et mål å finne ut hvordan organisatoriske og tekniske tiltak kan brukes og ses i sammenheng, og hvordan tekniske tiltak kan implementeres, vurderes og dokumenteres.
