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.

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.

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.

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.

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 [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

Abstract [en]

This paper presents a set of recommended reaction-To-fire test methods and related criteria for different construction products and furnishing products for use on offshore petroleum industry facilities. The system was first developed and published in 2008, as a response to performance based fire safety regulations. It has since then been extensively used by petroleum companies operating on the Norwegian shelf. The recommendations have been revised and updated recently to take revisions and developments of regulations, standards and test methods into account. These recommendations can be used as a part of the risk management system where the fire safety in high risk application areas shall be controlled, and are not limited to application of materials on facilities in the offshore petroleum industry only.
