    Fire Impact Tool- Measuring the impact of fire suppression operations on the environment2021Ingår i: Fire safety journal, ISSN 0379-7112, E-ISSN 1873-7226, Vol. 120, artikel-id 103071Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In Sweden the responsibility for environmental damage when emergency responders are called to an incident is increasingly focussing on the responders. The problem is that most incident response personnel do not have the training and expertise to assess the environmental consequences of their suppression operations. The Fire Impact Tool was developed for training responders about how fire effluents and suppression media affect air, surface/groundwater and soil. The tool has three interdependent parts: fire models (for vehicles and enclosures), an environmental risk assessment (ERA) model for local impacts, and a life cycle assessment (LCA) model for global impacts. Users can create two scenarios that are compared with a reference case in which responders arrive at the incident and prevent the fire from spreading beyond the vehicle or enclosure but do not suppress the fire. The Fire Impact Tool is not intended for use during an actual fire incident. This work does not answer every question for every possible fire scenario, but it does provide a framework for deeper, broader, more comprehensive training and pre-planning. This is a necessary step toward a future in which responders are prepared to make informed decisions about firefighting strategies and tactics that include environmental consequences.

    Fire suppression and manual firefighting of batteryelectric vehicle fires on ro-ro ships2023Ingår i: Proceedings of Seventh International Conference on Fires in Vehicles, 2023, s. 107-Konferensbidrag (Refereegranskat)
    Abstract [en]

    The increased use of electric vehicles has raised a concern about firefighting measures including water spray fire suppression systems (often denoted “drencher systems”) and tactics and equipment used for manual firefighting on ro-ro cargo and ro-ro passenger ships. A test series involving testing of two pairs of geometrically similar internal combustion engine vehicles (ICEV’s) and battery electric vehicles (BEV’s) under as equal test conditions as possible were conducted to investigate the performance efficiency of the drencher system. In addition, manual firefighting equipment and tactics was evaluated on three BEV fire tests. It is concluded that a fire in the two types of vehicles is different but share similarities. However, a fire in a BEV does not seem to be more challenging than a fire in an ICEV for the drencher system design given in current international recommendations. Similarly, there are common (e.g., handheld fire extinguishers and hoses) and new (e.g., fire blanket and water-cooling device) manual firefighting equipment that effectively can be used to control or limit a BEV fire.

    Safe and Suitable Firefighting2022Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The level of protection for personal protective equipment (PPE) in firefighting is important for Swedish shipowners; they want to be sure that the equipment they provide is sufficiently safe for the types of fires that can occur onboard. Shipowners also want to be updated on risks related to the carriage of alternative fuel vehicles (AFVs). Safety products and equipment used onboard ships with a European flag must be certified in accordance with the Marine Equipment Directive (MED) and follow the regulations in the International Convention for the Safety of Life at Sea (SOLAS). For fire suits, this means that they must be certified according to one of three standards listed in MED. Two of these standards cover suits used in special cases, with very intense radiant heat, and should only be worn for short periods. The third standard, EN 469, is the same standard that is referred to the PPE Regulation 2016/42, making EN 469-approved fire suits used among European firefighters ashore. However, EN 469 contains two different performance levels where the lower level is not suitable for protection against risks encountered when fighting fires in enclosures. Based on a user study and a risk assessment for AFVs, a set of suggested changes to MED and SOLAS were prepared, together with a set of recommendations for operators that were found important but not subject for regulations. A ready-to-use quick guide, containing the most important results, has been developed for operators.

    Evaluation of Road Tunnel Fire Safety and Risk2016Ingår i: Proceedings from the 7th International Symposium on Tunnel Safety and Security, 2016, s. 217-228Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The aim of this paper is to help a decision maker to decide whether a road tunnel is safe enough with respect to fire safety. Safety objectives as well as societal, ethical and political objectives are identified for the decision. It is argued that most uni-directional tunnels that comply with minimum EC requirements, with a longitudinal ventilation system along the traffic flow fails safely in the event of fire. Catastrophic fires should not be an issue, even for a risk averse decision maker. Considering the issue of fairness the tunnel is argued to be safe enough, and resources are either better used elsewhere or should be allocated so that the utility is maximized. For high-risk bi-directional tunnels, catastrophic fires could be an issue, in particular if there is no separate emergency pathway. Then a risk aversive decision maker may take extra safety measures against such fires. A risk neutral decision maker would allocate resources so that the utility is maximized. Road tunnel regulation should set minimum requirements rather than cautionary requirements and allow for a probabilistic approach.

    Policyutveckling av riskhantering för återvinning av avfall2020Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Sverige och EU har idag högt ställda förväntningar och mål på en cirkulär ekonomi. Inom flera områden finns dock ett stort glapp mellan dessa mål och hur återvinningsbeslut hanteras i praktiken. Ett tidigare RE:Source projekt under 2019 identifierade flera övergripande principer och faktorer för återvinning av avfallsbeslut (Gehandler & Millgård, 2020). Denna studie är en fortsättning och argumenterar för att tvetydighet är en viktig faktor för att minska glappet mellan politiska mål och återvinning i praktiken. Tvetydighet handlar dels om tolkningen och tillämpningen av lagar och begrepp såsom vad som är avfall eller produkt, samt om hur risker och nyttor ska värderas.

    Risks with hydrogen in underground facilities2023Rapport (Övrigt vetenskapligt)
    Abstract [en]

    RISE has previously studied alternative fuels, such as batteries and gaseous fuels including liquid and compressed hydrogen (GH2). Each fuel has its unique risks. Liquid hydrogen (LH2) is a cryogenic fluid and is thus stored in cooled liquid form, which entails specific risks. The purpose of this report is to, based on the current state of research, map the risks of hydrogen in underground facilities in relation to conventional fuels and investigate which technical measures can be taken to reduce the risks. Unlike diesel, hydrogen (and for instance methane or gasoline) has such a low flash point that an emission can be ignited at normal temperature by a small ignition source. Hydrogen is also very buoyant, with strong diffusion and dispersion characteristics, accordingly it accumulates at high points in a subsurface environment. Hydrogen requires very low energy to ignite at or near stoichiometric mixing with air at around 30%. The lower flammability limit is, compared to other flammable fuel/air mixtures high at around 4%, which means that many smaller releases in ventilated spaces will be too lean. Explosions would require a higher hydrogen concentration, above 8% or more. In subsurface environments, containment contributes to a higher increase in pressure, as well as an increased risk of explosion for both GH2 and LH2. The handling of hydrogen underground can therefore be seen as problematic. When it comes to hydrogen as a vehicle fuel, however, there are safety measures to achieve equivalent safety with conventional vehicles. For example, the shut-off valve (mandatory in regulation) on each tank that reduces the risk of leakage, and through the development of explosion-free composite tanks (not mandatory in regulation) in the event of fire that provide a less dangerous fire scenario than a diesel or gasoline tank in case of fire. When it finally comes to transporting hydrogen, pipelines are the long-term sustainable (and safe) alternative. Transport of compressed hydrogen gives a low amount of gas per trailer and entails relatively higher risks than CNG underground, for example in tunnels. The usage of liquid hydrogen, so far, has an impressive safety record, events like BLEVE or fireballs appear to be rare. The transport of liquid hydrogen provides a larger amount of hydrogen per trailer (than for compressed hydrogen) with a relatively lower risk than, for example, LNG in the open, but a slightly higher risk for explosion of accumulated gas compared to GH2 in enclosed spaces. The safety requirements for transport of compressed hydrogen are less stringent than for road vehicles, e.g., with regard to shut-off valves and melt-fuses and could be improved. Several risk mitigation measures for tunnels and other underground facilities have been identified.

    The theoretical framework of fire safety design: Reflections and alternatives2017Ingår i: Fire safety journal, ISSN 0379-7112, E-ISSN 1873-7226, Vol. 91, s. 973-981Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article aims to contribute to discussions and reflections upon the practice and theory of fire safety design. Are we reaching the results we want by the best available means? The theoretical framework of fire safety design is today restricted by a linear design process where mainly quantitative data and methods matters. A deterministic approach to safety ignores the decision-making context and considers each objective in isolation. Alternative methods for the fire safety design could view the design work as an iterative problem solving process between the designers and the stakeholders. Then decision making theory can be applied to solve the problem. In the iterative process key objectives are identified and the problem and its solutions are being reframed, creative inherently safer (cannot fail) and fail safe (forgiving to errors) alternatives are initially aimed at. Design should further embrace a function-centred view of the human-technology-structure system. A utilitarian evaluation that includes also qualitative factors can identify the best trade-offs between conflicting objectives. With a diversity of perspectives on fire safety design, the field of fire safety will be strengthened and be able to assist a rapidly changing world.

    Limit-Based Fire Hazard Model for Evaluating Tunnel Life Safety2015Ingår i: Fire technology, ISSN 0015-2684, E-ISSN 1572-8099, Vol. 51, nr 3, s. 585-614Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Despite the simple one-dimensional symmetry of a tunnel with a longitudinal ventilation flow, risk analysis often comprises resource intensive and complex calculations. The purpose of this article is to present a simple yet precise limit-based model for assessing the possibility for a safe tunnel evacuation. To estimate the model uncertainty, fire dynamics calculations were compared to experimental data. The calculations performed well compared to experimental test data, showing an average difference between 5 and 40% in predicting the time available for evacuation, when criteria for visibility, air temperature, CO, CO2 and O2 concentration and heat flux were calculated. For steadily growing fires, visibility showed a low sensitivity to variability in input parameters with a relative difference at 9% compared to experimental data. Due to several factors it was not possible to estimate the accuracy of HCN calculations. Visualizing the hazards in a time–distance diagram revealed visibility to be the key indicator for calculating ASET for a broad set of plausible input parameters. This resulted in a simple expression for calculating ASET and consequently a simple condition for evaluating life safety.

    Principer och strategier för ventilation vid brand i undermarksanläggningar2018Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The report describes different underground systems including mines and tunnels during construction (tunneling). The key factors that affect fire development in underground systems are described. Proposal and recommendations for ventilation strategies in case of fire are given. The report covers both fuel- and ventilation-controlled fires. In general, a minimal ventilation limits the fire growth and may even inert the fire through ascended smoke. A minimal ventilation also contributes to improved conditions for a first fire extinguishing attempt and evacuation.

    Performance-based design of road tunnel fire safety: Proposal of new Swedish framework2014Ingår i: Case Studies in Fire Safety, ISSN 2214-398X, Vol. 1, nr 1, s. 18-28Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper contains a proposal of new Swedish framework for performance-based design of road tunnel fire safety derived from Swedish and European regulation. The overall purpose of the guideline is to protect life, health, property, environment, and key societal functions from fire. The guideline is structured into five key groups of requirements: #1 Proper management and organisation, #2 to limit the generation and spread of fire and smoke, #3 to provide means for safe self-evacuation, #4 to provide means and safety for the rescue service, and #5 to ensure load-bearing capacity of the construction. Each group contains a hybrid of prescriptive requirements, performance-based requirements, and acceptable solutions. Prescriptive requirements must be fulfilled, however, it is the choice of the design team to either adopt the proposed acceptable solutions, or to design alternative solutions by verifying that performance-based requirements are satisfied. For verification of performance-based requirements through risk analysis the operational, epistemic, and aleatory uncertainties are considerable. Therefore, a scenario-based risk analysis with several specified input variables and methods is recommended for verification of #3 and #5. Indispensable complements are scenario exercises, emergency exercises and similar methods that validate the design and highlight organisational aspects. The proposed design guide has been developed by the authors together with the advisory group established for the work.

    Risker med nya energibärare i vägtunnlar och underjordiska garage2016Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Due to environmental concern, policy goals for transportation aim at using renewable fuels. These include gaseous fuels such as motor gas, methane or hydrogen and electric vehicles. This research project focuses on a literature review to understand the emerging risks with alternative propellants in road tunnels and underground garages. Gaseous fuels and electric vehicles pose new risks compared to the liquid fuels that we are more used to. In particular this concerns gaseous fuels and the risk for pressure vessel explosion, and the release of toxic substances such as hydrogen fluoride from Li-ion batteries undergoing thermal runaway. Two workshops were organized to get feedback from stakeholders and to initiate discussions. Future research, risk reducing measures, rescue service guidance and changes of regulation and guidelines are discussed and proposed.

    Risks associated with alternative fuels in road tunnels and underground garages2017Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Due to environmental considerations, much current transportation policy development is aimed at increasing usage of renewable energy sources. These include gaseous fuels such as LPG, methane, and hydrogen, along with electricity. This research project focused on a literature review that was intended to research the risks involved in using alternative fuels in road tunnels and underground garages. Gaseous fuels and electric vehicles pose new risks that we, due to our greater familiarity with liquid fuels, are unused to. The greatest of these relate to gaseous fuels and pressure-vessel explosions, and the release of toxic gases such as hydrogen fluoride from Li-ion batteries undergoing thermal runaway. Two workshops were organised to obtain feedback from stakeholders and initiate discussion regarding the issue. Future research, risk-reducing measures, rescue service guidance, and changes to regulations and guidelines are discussed and proposed in this report.

    CNG vehicle containers exposed to local fires2019Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Fuels with a high energy density have contributed to the development of modern communities. On the other hand, fuels contain energy that, during some conditions, can result in incidents, not least within transportation. CNG vehicles are designed according to safety standards of UNECE, including events such as fire. In case of a fire a thermally activated Pressure Relief Device (TPRD) should empty the container before a pressure vessel explosion potentially can occur. CNG tanks are according to UNECE regulation 110 tested against a 1.65 m long pan fire. However, local fires are not included in these tests. This report presents fire tests of CNG containers performed both with a UNECE compatible fire source and with a local fire source. Any pressure vessel explosion and jet flames were characterized for two different types of CNG containers, namely steel and composite. In five out of six tests the safety of the CNG containers prevailed also in the event of a local (0.24 m by 0.24 m) pan fire, meaning that no pressure vessel explosion occurred. In real vehicle fires, where the fire extends from its local characteristics to a more developed fire that expose the CNG containers to a larger extent, these tests support that TPRDs most likely will activate. The experience from running these test series call for that the fire source should be more accurately defined with regards to fuel and dimensions and a local fire should be included in the UNECE Regulation 110.

    Tactical depressurization of hydrogen containers with civilian rifle and ammunition2022Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    There can be situations, for example if gas containers have been damaged in a vehicle crash, when the fire and rescue service would like to depressurize the gas containers through shooting with a civilian rifle. Modern high-pressure hydrogen containers are designed for a working pressure of 700 bars. This means that they have a very thick and strong shell made of composite material. At the same time the fire and rescue service only have access to civilian rifles and ammunition that can be bought for hunting purposes. Thus, tactical and safe depressurization of hydrogen containers is a big challenge. RISE have, together with the Södra Älvsborgs Fire and Rescue Services (SÄRF), Swedish Civil Contingency Agency, and Lund University conducted shooting tests of gas tanks mounted on a hydrogen gas vehicle and three stand-alone hydrogen gas tanks. The shooting tests were conducted at Remmene shooting field in Sweden. Thirteen shooting tests with hydrogen tanks placed in favouarable positions were performed. Out of these, only four tests were succesful in puncturing the individual gas tank in a single shot. Furthermore, two unwanted events occurred; one rupture (after 7 shots) and two powerful jets (after 20 and one shot respectively). This shows that further development and research is required in order to develop a method to safely depressurize high pressure hydrogen tanks.

    Principles and policies for recycling decisions and risk management2020Ingår i: Recycling, E-ISSN 2313-4321, Vol. 5, nr 3, artikel-id 21Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Swedish recycling businesses argue that the Non-Toxic Environmental target gets too much weight and that resource efficiency gets too little focus, which results in decreased recycling. The purpose of this paper is to highlight different factors that recycling of waste decisions should consider, as well as contributing to a constructive discussion of the overall principles and policies for recycling. How recycling works in practice is explored based on nine interviews with stakeholders from the governmental agency level to recycling businesses. Theory with regards to ethics, risk, decision-making, governmental policy and laws is summarised. Finally, the discrepancy and connection between practice and theory is analysed. If recycling of waste is seen as a decision problem, the choice is between to recycle (in different ways) or not to recycle (i.e., energy recovery and/or landfill). Based on risk and decision theory, all relevant goals should be considered. This requires a broader problem framing when goals are in conflict. All parties agree that recycled and virgin material should be treated equally. From a higher policy perspective, it should then be demonstrated that any use of material (recycled and/or virgin) minimize environmental impact and promotes long-term sustainability. © 2020 by the authors.

    TUSC HANDBOK Brandskydd under byggtiden för tunnlar och andra undermarksanläggningar: Med exempel på risker och förslag på åtgärder2022 (uppl. 2)Bok (Övrigt vetenskapligt)
    Abstract [sv]

    Ingen ska skadas eller drabbas av sjukdom på grund av sitt arbete. Detta ställer krav på genomtänkt utformning av brandskyddet och utrymningssäkerhet under byggtiden för tunnel eller andra undermarksanläggningar. Ett syfte med denna handbok är att tydliggöra vilka krav som ställs på brandskydd under byggtiden, samt ge exempel på vanliga brandrisker och förslag på hur dessa kan hanteras.

    Handboken vänder sig till aktörer, såsom byggherrar, projektörer, entreprenörer och byggarbetsmiljösamordnare, involverade i planering, projektering och byggnation av undermarksanläggningar. Med undermarksanläggning menas här väg-, järnväg-, vatten-, avlopps- kabel- och distributionstunnel, bergrum och slutförvar.  Handboken omfattar inte gruva, byggnader ovan mark, eller brandskydd i färdigställd anläggning.

    Handboken är avsedd att användas som vägledning och inspiration vid planering, projektering, genomförande, samt utbildning och övning med fokus på brandsäkerhet.

    Återvinning av avfall: Beslut och riskbedömning2020Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Syftet med den här studien har varit att synliggöra olika faktorer som en besluts- eller riskbedömningsmetod kan beakta i olika utsträckning, att göra en jämförelse mellan nuvarande metod eller praxis och besluts- och riskbedömningsmetoder från andra områden, till exempel trafik, innehåll av kemikalier i produkter, brand och olyckor, eller riskhantering i stort, samt bidra till en konstruktiv diskussion gällande mål och övergripande principer för återvinning av avfall. Bakgrunden till projektet är att det har framgått att återvinning av anläggningsmassor har minskat i och med tillämpningen av Naturvårdsverkets handbok (2010:1). En åsikt som framkommit från en utvärdering av handboken är att miljömålet Giftfri miljö får för stor tyngd och att resurshållning får för lite fokus. I takt med att klimatfrågan blir alltmer akut, och eftersom återvinning i många fall ger en minskad klimatpåverkan, kan denna begränsning ifrågasättas. Det är dock idag oklart hur avvägningen mellan en giftfri miljö och resurseffektivitet ska göras.En litteraturstudie har genomförts i två delar, dels gällande beslut och riskhantering och dels gällande etik. Den första delen syftade till att ge teori om riskbeslut utifrån grundläggande steg som bör ingå i en beslutsprocess. Den andra delen av litteraturstudien, etiken, presenterar teori om etiska aspekter kopplade till besluten. Etiken är central eftersom den länge sökt svar på frågan hur vi bör handla.Vidare har även nio intervjuer genomförts med olika intressenter, från myndighetsnivå till verksamhetsutövare, för att fånga hur återvinning av avfall fungerar i praktiken. Från intervjuresultatet utkristalliserades temat ”Målet Giftfri miljö och de svårigheter som kan uppstå vid dess praktiska tillämpning”. som diskuterades vidare i ett arbetsmöte. Inbjudna till arbetsmötet var framförallt de som hade intervjuats och som hade relevanta roller för det valda temat.Om återvinning av avfall ses som ett beslutsproblem står valet mellan att återvinna (på olika sätt), eller att inte återvinna (dvs. deponering, förbränning eller energiutvinning). Utifrån beslutsteori bör alla mål som berörs beaktas. Detta kommer troligtvis för svårare fall kräva ett breddat perspektiv, se figur nedan, som inkluderar miljörisker kopplade till de olika alternativen.

    Med ett bredare perspektiv inses att inget alternativ är riskfritt. En multikriterieanalys kan väga de olika faktorerna mot varandra för att se vad som väger tyngst, vad som ur miljöbalkens perspektiv är mest rimligt, dvs. ger mest miljönytta. Ett bredare perspektiv gynnar långsiktig hållbarhet och på sikt alla miljömålen.På ett övergripande plan bör återvunnet och jungfruligt material behandlas lika. Ur ett cirkulärt perspektiv borde man på motsvarande sätt behöva visa att valet av material främjar långsiktig hållbarhet.

    BREND 2.0 - Fighting fires in new energy carriers on deck 2.02022Rapport (Övrigt vetenskapligt)
    Abstract [en]

    The project BREND investigated risk with alternative fuel vehicles inside ro-ro spaces. BREND 2.0 is a continuation and has in particular investigated two of the major risks identified in BREND, namely the risk of toxic gases from electric vehicle fires and the risk of a pressure vessel explosion for fire exposed biogas or hydrogen vehicle tanks. Simulations of electric vehicle fires inside a ro-ro space based on real input fire data has been performed. Field experiments that investigate the conditions that can lead to pressure vessel explosion were made with fire exposed biogas and hydrogen tanks. Recommendations are given about how ro-ro space fires in alternative fuel vehicles, or indeed any vehicle fire, can be managed.

    Qualitative Risk Analysis of Dangerous Goods with Alternative Propellants2016Ingår i: Proceedings from the 4th International Conference on Fire in Vehicles - FIVE 2016, 2016, s. 247-248Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    This qualitative risk analysis of dangerous goods transports with alternative propellants was ordered by the Swedish Civil Contingencies Agency (MSB). Scenario combinations consisted of five alternative fuels, six accident scenarios and five types of dangerous goods cargo. The alternative fuels were: methane, hydrogen, ethanol, methanol and dimethyl ether. The accident scenarios consisted of refuelling, fire in tire or engine, tunnel accident, road collision and sabotage of fuel tank. The dangerous goods were limited to: ammonium nitrate, petrol/diesel, methane, ethyl chloride, and EX/II cargo as defined in the ADR regulation. The main identified risks are due to the risk of pressure vessel explosion of gaseous fuels as it: 1) Threatens to detonate explosive load or ammonium nitrate. 2) Cause rescue service to take a defensive approach which will lead to larger consequences. Since there are sustainable liquid fuel alternatives such as bio diesel, this may be a better choice for dangerous goods transportation.

    Förnybar flytande biogas (LBG) till sjöfart i praktiken2024Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Reducing the environmental and climate impact of shipping propelled by liquefied natural gas (LNG) requires the introduction of alternative fuels such as liquid biogas/biomethane (LBG) (Jivén et al., 2022). Today, only a small part of the biomethane produced in Sweden is liquefied into LBG and an even smaller part is used as fuel for shipping. The price and availability of biogas is governed by supply and demand in an international market where shipping, industry and heavy trucks demand biogas. The biogas then needs to be processed into upgraded biogas (biomethane) or LBG quality in order to be transported and used in the respective sectors inside and outside of Sweden. The trend is for a larger proportion of biogas to be liquefied into LBG. The market has thus gone from a local market, where biogas was produced in the city's wastewater treatment plant and the city buses ran on biogas, to an international market where biogas often is transported in the same way as fossil gas and marketed using the fossil gas together with certificates. The project "Renewable liquid biogas (LBG) for shipping in practice" was carried out by IVL Swedish Environmental Research Institute and RISE in 2023 together with stakeholders from the shipping sector, ports and industry organizations for biogas. The project has studied the conditions required to make LBG available to shipping in practice at Swedish ports. The study shows that the major obstacles to an established use of LBG in the shipping sector in Sweden today are pricing/willingness to pay that is affected by international market prices, lack of suitable logistical solutions as well as the absence of the piece of the puzzle that is the business model and cooperation needed to make available the large volumes of biogas that shipping may demand. The stakeholders in the project estimate their total need of biogas to 3 TWh in a short term, and 10 TWh in a longer term. The project has identified a number of conclusions and recommendations for future work, including that the potential for biogas is large and untapped, but that new solutions for the distribution and logistics of LBG are needed. There is a clear interest from maritime actors as they see biogas as a strategic solution and the dialog between actors in the industry remains important. A change in the tax system could be needed so that more actors can use the green gas principle for LBG. In addition, a functioning "marketplace" is needed, which simplifies for sellers and buyers of LBG, and agreements/contracts are needed that are longterm and to a greater extent based on the costs of producing and providing LBG.

    Test Method and Performance of Fire Detection Systems in Tunnels2016Ingår i: Proceedings from the 7th International Symposium on Tunnel Safety and Security, 2016, s. 485-496Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The results of a study carried out for the Swedish Transport Administration on fire detection in road tunnels is presented. Laboratory tests and numerous large-scale tests were carried out in order to verify a proposal for a test method for fire detection systems. The main aim was to investigate possible fire detector systems and to see if they could fulfil the requirement given by the Swedish Transport Administration to detect the fire within 90 seconds. The tests are presented as well as a recommendation for testing detection systems in Swedish road tunnels. In order to perform the fire test, pans of different sizes were tested in order to obtain a reasonable fire size. The method proposed requires the use of three 0.6 m diameter standard pans, each containing eight litres of 95 octane gasoline, and air flow velocities of 2 m/s and 6 m/s. It was found out that using only one 0.6 m pan is sufficient if early warning is required without identifying the position for the fire-fighting system.

    Metoder för att testa dukar och membran i tunnlar och bergrum2018Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Tunnel and rock lining systems are used for drainage and icing protection. These systems can consist of any combination of concrete, metal, plastic or textile. The report summaries the available methods, both for testing and for installation. The large variation in both systems and test methods often make it difficult for constructors or designer to understand the importance of different methods. The report gives indication of what type of linings exists and how to ensure the fire safety of such systems. Fire safety properties can be verified in three different ways: #1 Full systems can be tested in full scale fire tests, #2 a section of the system can be tested in standardized furnace tests, or #3 plastic and/or textile membrane can be tested with regards to requirements on fire spread. It is suggested to require that a fire should not be able to propagate in the system. This can be verified with #3 above requiring class B, C or D according to EN 13501-1. If the lining system offers structural fire protection, it can be verified suing #2 above.

    Proceedings from the Seventh International Conference on Fires in Vehicles: STAVANGER, NORWAY, APRIL 24-25, 20232023Proceedings (redaktörskap) (Refereegranskat)
    Abstract [en]

    These proceedings include papers and extended abstracts from the 7th International Conference on Fires in Vehicles – FIVE 2023, held in Stavanger, Norway, April 24-25, 2023. The proceedings include an overview of research and regulatory actions coupled to state-of-the-art knowledge on fire related issues in vehicles, such as passenger cars, buses, trucks and trains, or related infrastructure, such as car parks or vehicle transport at sea. Fires in transport systems are a challenge for fire experts. New fuels that are efficient and environmentally friendly are rapidly being introduced, with emphasis on high energy density batteries. This rapid development, however, introduces new fire risks not considered previously and we risk getting a situation where we do not have enough knowledge to tackle them. In this context FIVE represents an important forum for discussion of the fire problem and for exchange of ideas. Fire protection in road, rail, air, and sea transport is based on international regulations since vehicles cross borders and the safety requirements must be the same between countries. Therefore, understanding of safety and regulations must be developed internationally and the FIVE-conference has a significant role to play as a place to exchange knowledge. FIVE attracts researchers, operators, manufacturers, regulators, rescue services and other key stakeholders. Of particular value is the mix of expertise and the international participation in the conference. The conference is unique as it includes fires in different types of vehicles. In recognition of the fact that many of the fire problems faced by these vehicles are the same, the solutions to them can also be similar. In the proceedings you will find papers on vehicle fire development, bus fires, alternative fuel and electric vehicles, and car park fires. We are grateful to the renowned researchers and engineers presenting their work and to the keynote speakers setting the scene. We sincerely thank the scientific committee for their expert work in selecting papers for the conference.
