    Effective Firefighting Operations in Road Tunnels2010Report (Refereed)
    Abstract [en]

    The main purpose of this study is to develop operational procedures for fire brigades in road tunnels. Although much progress has been achieved in various fields of fire safety in tunnels, very little attention has been paid specifically to fire fighting in tunnels. This study is focused on obtaining more information concerning how effectively the fire brigade can fight road tunnel fires and what limitations and threats fire brigades may be faced with. This knowledge can help parties involved in tunnel safety to understand safety issues and enhance the level of fire safety in road tunnels. The report is divided into three main parts. The first part consists of a review of relevant studies and experiments concerning various key parameters for fire safety and emergency procedures. The history of road tunnel fires is then summarised and analyzed. Among all road tunnel fires, three catastrophic tunnel fires are highlighted, focusing on the activities of fire brigades and the operation of technical fire safety facilities. In the second part specific firefighting operations are developed. This has been based on previous experience and new findings from experiments performed in the study. In the last part, information is given on how the proposed firefighting operations can be applied to the management of fire safety for road tunnels. Two proposals are developed and presented: fire scenarios for firefighting strategies and tunnel classification models for risk management for fire brigades.

    EPS insulated façade fires from a fire and rescue perspective2013In: 1st International Seminar for Fire Safety of Facades, FSF 2013, 2013, Vol. 9, p. 5003article id 05003Conference paper (Refereed)
    Abstract [en]

    This paper highlights the challenges the fire and rescue services can meet at façade fires involving EPS insulation during construction and use of a building. The EPS characteristics are discussed in respect to the fire and rescue operation and results from orientating fire tests performed at a fire and rescue services training and test field are presented. Types of evacuation solutions, involving the fire and rescue services, where façade fires can delay or completely rule out the possibilities for safe evacuation, are presented. The restrictions in the Swedish building codes regarding use of combustible insulation are analysed and reflections over the practical problems with following the instructions to keep an EPS insulated façade safe through the building's whole lifespan are made. A number of occurred fires involving EPS are discussed and analysed from a fire and rescue perspective. Finally, recommendations are given for the fire and rescue services and future research fields are proposed.

    Measurement of self‐heatingpotential of biomass pellets with isothermal calorimetry2017In: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 41, no 8, p. 1007-1015Article in journal (Refereed)
    Abstract [en]

    In order to assess the risk for spontaneous combustion of biomass pellets during storage it is important to know how prone the fuel is to self-heating, i.e. to determine the reactivity. 

    This article presents the results from isothermal calorimetry tests performed on 31 different biomass pellet batches. The purpose of the tests has been to characterize pellets by measuring the reactivity and investigate how the pellet composition influences the heat release rate and thereby the self-heating potential of pellets. 

    The results from the tests clearly indicate that there is a significant difference in reactivity between different types of pellets. The tested high reactive pellet batches reached maximum specific heat release rates (HRRmax) of 0.61-1.06 mW/g while pellet batches with low reactivity showed HRRmax of 0.05-0.18 mW/g. The tested batches were primarily ranked based on HRRmax but an alternative ranking based on specific total heat release rate during the test period was also used for comparison. 

    The test results also indicate that pine/spruce mix pellets are significantly more reactive than all other types of pellets tested and that pellets consisting of 100 % pine are more reactive than pellets consisting of 100 % spruce. Pellets produced from wine pruning/grape pomace (winery wastes), straw or eucalyptus are not very reactive compared to pellets consisting of pine/spruce. 

    The results also show that the reactivity of the pellets can be reduced by either introducing certain kinds of anti-oxidants into the pellets or by extracting lipids from the raw material of pellets.

    Development of a screening test based on isothermal calorimetry for determination of self-heating potential of biomass pellets2017In: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 41, no 8, p. 940-952Article in journal (Refereed)
    Abstract [en]

    For the risk for spontaneous combustion in storage of biomass pellets to be assessed, it is important to know how prone the fuel is to self-heating. There are traditional methods that are used to determine self-heating characteristics of fuels, eg, basket heating tests. The results from basket heating tests indirectly give the reactivity from a series of tests at high temperatures. This paper presents a sensitive screening test procedure for biomass pellets using isothermal calorimetry for direct measurement of the heat production rate at typical bulk storage temperatures. This method can be used to directly compare the reactivity of different batches of biomass pellets. The results could be used, eg, by storage security managers to gain better knowledge of their fuels propensity for self-heating and thereby for safer storage. A large number of tests have been performed to develop the test procedure presented. Different parameters, such as temperature, type of the test sample (powder/crushed or pellets), mass of test sample, and preheating time, have been varied. Furthermore, gas concentrations in the sample ampoule have been measured before and after some tests to study the oxygen consumption and the formation of CO and CO2. Three different types of pellets with different characteristics were tested to assess the variation in behaviour. Based on these tests, a screening test procedure is presented with a test temperature of 60°C, a sample size of 4 g, a 15-minute preheating period at the test temperature, and 24-hour test duration.

    Medium-scale self-heating tests with biomass pellets2020Report (Other academic)
    Abstract [en]

    A commonly known problem with storage of biomass pellets is the risk for self-heating. The propensity for self-heating depends on several parameters e.g. type of pellets, humidity, ventilation, temperature, type of storage and handling prior to storage.

    Within the framework of the research project SafePellets (Safety and quality assurance measures along the pellets supply chain) a medium-scale methodology to assess the propensity for self-heating has been developed. In addition, methods to study carbon monoxide (CO), carbon dioxide (CO2) and oxygen (O2) concentrations as well as different aldehydes have been tested and evaluated in this study.

    Biomass pellets from three different sources, i.e. 100 % pine; a mixture of spruce and pine and a mixture of straw, seed residue and spruce, were tested in a 1 m3 test container. The test container and the pellets were pre-heated and kept at the nominal test temperature until self-heating occurred, or the test was terminated. Temperatures were measured at more than 40 different positions and gas samples were extracted from the test container and analysed.

    Differences were observed as a function of pellet type, but also as a function of nominal test temperature and ventilation. Significant levels of CO and CO2 and a reduced level of O2 were observed direct after the pre-heating, indicating oxidation of the pellets. Ten different tests were made; ignition occurred in four of them. The higher the nominal test temperature, the higher propensity for self-heating. When ignition occurred, the concentrations of CO and CO2 increased rapidly. It was found that the ventilation conditions were important. In some of the tests, natural convection caused the pellet bulk to cool. In other tests, when the test container was closed, the oxygen concentration dropped, and self-heating was reduced.

    Measurements of CO, CO2 and O2 contributed with information about the tests. However, the results from aldehyde measurements were unconcise and the values have only been used as indicative. Identified aldehydes were hexanal, butyraldehyde, valeraldehyde, formaldehyde, propionaldehyde, acetaldehyde and acrolein.

    Effect of cross section and ventilation on heat release rates in tunnel fires2016In: Tunnelling and Underground Space Technology, ISSN 0886-7798, E-ISSN 1878-4364, Vol. 51, p. 414-423Article in journal (Refereed)
    Abstract [en]

    Model scale fire tests were performed in tunnels with varying tunnel widths and heights in order to study the effect of tunnel cross-section and ventilation velocity on the heat release rate (HRR) for both liquid pool fires and solid fuel fires. The results showed that for well ventilated heptane pool fires, the tunnel width nearly has no influence on the HRR whilst a lower tunnel height clearly increases the HRR. For well ventilated solid fuel fires, the HRR increases by approximately 25% relative to a free burn test but the HRR is not sensitive to either tunnel width, tunnel height or ventilation velocity. For solid fuel fires that were not well ventilated, the HRRs could be less than those in free burn laboratory tests. In the case of ventilation controlled fires the HRRs approximately lie at the same level as for cases with natural ventilation.

    Fire development in different scales of train carriages2014In: Sixth International Symposium on Tunnel Safety and Security. New Zealand. 2014-03-12--14, 2014, Vol. 11, p. 203-15p. 302-315Conference paper (Other academic)
    Abstract [en]

    A fire development analysis of three series of train carriage fire tests in different scales was carried out. These train carriage fire tests included 1:10 model scale tests, 1:3 model scale tests and 1:1 full scale tunnel tests. The heat release rate (HRR) correlations between different scales of carriage fire tests were carefully investigated. The mechanism of fire development is very similar in different scales of tests involving fully developed fires. After the critical fire spread, the fire travelled along the carriage at an approximately constant speed. The maximum heat release rate obtained for a fully developed fire is dependent on the ventilation conditions and also the type and configuration of the fuels, and a simple equation has been proposed to estimate the maximum heat release rate. A global correction factor of the maximum heat release rate is presented and examined.

    Brandsäker energilagring - Sammanställning av risker och forskningsbehov2018Report (Other academic)
    Abstract [en]

    There is a large interest in the possibilities in storing produced energy that is not needed at that particular moment or to store energy when the cost for production of electricity is low. For this reason, different types of energy storage systems are used. With a fast development of new technologies and new forms of application for energy storage systems, it is important to also study the existing and potential risks with these types of systems.

    This prestudy describes the field, its risks and needs for research. It focuses on risks associated with fire, including explosions and when relevant the production of toxic gases. Although the main focus of the prestudy is different types of energy storage systems, the report contains information also on risks associated with storage of solid biofuels and waste. This means that the report contains information on risks and needs for research for batteries, hydrogen, biogas, liquified gases, biofuels and waste.
