    A comparative study of test methods for assessment of fire safety performance of bus interior materials2013In: Fire and Materials, ISSN 0308-0501, E-ISSN 1099-1018, Vol. 37, no 5, p. 350-357Article in journal (Refereed)
    Abstract [en]

    This work concerns the assessment of fire performance of interior materials in buses. The widely used test method ISO 3795/FMVSS 302 has received much criticism mainly based on the fact that the test is a small-scale method not suited for bus fires induced by for example fire in the engine compartment or fire in a tyre. Furthermore, test specimens are oriented horizontally, whereas much fire spread in a real bus fire occurs on vertically oriented products. Seventeen products were investigated: 11 textiles, four solids and two insulations. Three test methods were compared: ISO 3795, ISO 6941 and ISO 5658-2. Given the existing criteria for interior materials, it was found that ISO 6941 and ISO 5658-2 place harder requirements on the materials. When the three methods were compared, it was found that ISO 3795/FMVSS 302 and ISO 6941 are insufficient for simulating bus fires typically occurring today. Such fires are often initiated by a fire in the engine compartment or in a tyre and can hardly be simulated by small-scale methods as ISO 3795/FMVSS 302 or ISO 6941 even if the ISO 6941 method to some extent gives results similar to the established large-scale ISO 5658-2 method.

    In-situ measurements of toxic gases in a tube furnace2009Report (Refereed)
    Abstract [en]

    Infrared Polarization Spectroscopy (IRPS) was used to detect and quantify HCl and HCN in an 800 mm long tube furnace. Pieces of a PVC-carpet or pellets of nylon 6,6 were continuously fed into the furnace producing a heavy smoke. This constitutes a very harsh environment from a diagnostic point of view due to the high smoke density and relatively long length of the furnace. Despite this it was possible to quantify HCl and HCN concentrations in the smoke down to a levels of 50 ppm using IRPS. The explanation for this success is twofold. Firstly the IRPS method is inherently almost noise free due to the use of crossed polarisers, creating a virtually zero background. Secondly the problem with laser beam attenuation due to scattering in the smoke, especially with soot particles, decreases in importance with the fourth power of the laser wavelength. This means that infrared measurements represent a great advantage over measurements in the ultraviolet or visible wavelength range. It is concluded that IRPS shows great promise as a new diagnostics tool in fire technology for small-scale as well as for large scale experiments. Furthermore the in situ nature of the method should be emphasized since this means that valuable information is obtained that can not be extracted from sampling methods such as MS/GC or FTIR for example. This information is important, for example, in egress calculations and analysis of fire chemistry. The method can easily be adapted for other gases such as HF, NO, NO2, HBr, CO and SO2.

    Limit-Based Fire Hazard Model for Evaluating Tunnel Life Safety2015In: Fire technology, ISSN 0015-2684, E-ISSN 1572-8099, Vol. 51, no 3, p. 585-614Article in journal (Refereed)
    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.

    Risker med nya energibärare i vägtunnlar och underjordiska garage2016Report (Other academic)
    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.

    Characterization of thermo-physical properties of EVA/ATH: Application to gasification experiments and pyrolysis modeling2015In: Materials, ISSN 1996-1944, E-ISSN 1996-1944, Vol. 8, no 11, p. 7837-7863Article in journal (Refereed)
    Abstract [en]

    The pyrolysis of solid polymeric materials is a complex process that involves both chemical and physical phenomena such as phase transitions, chemical reactions, heat transfer, and mass transport of gaseous components. For modeling purposes, it is important to characterize and to quantify the properties driving those phenomena, especially in the case of flame-retarded materials. In this study, protocols have been developed to characterize the thermal conductivity and the heat capacity of an ethylene-vinyl acetate copolymer (EVA) flame retarded with aluminum tri-hydroxide (ATH). These properties were measured for the various species identified across the decomposition of the material. Namely, the thermal conductivity was found to decrease as a function of temperature before decomposition whereas the ceramic residue obtained after the decomposition at the steady state exhibits a thermal conductivity as low as 0.2 W/m/K. The heat capacity of the material was also investigated using both isothermal modulated Differential Scanning Calorimetry (DSC) and the standard method (ASTM E1269). It was shown that the final residue exhibits a similar behavior to alumina, which is consistent with the decomposition pathway of EVA/ATH. Besides, the two experimental approaches give similar results over the whole range of temperatures. Moreover, the optical properties before decomposition and the heat capacity of the decomposition gases were also analyzed. Those properties were then used as input data for a pyrolysis model in order to predict gasification experiments. Mass losses of gasification experiments were well predicted, thus validating the characterization of the thermo-physical properties of the material. © 2015 by the authors; licensee MDPI, Basel, Switzerland.

    Brandrisker i transformatoreroch reläverksamhet medsupport2008Report (Other academic)
    Abstract [sv]

    Vid en brand, eller incident som kan leda till brand, ger en tidig upptäckt och omedelbar åtgärd en minimerad skadebild. De flesta ställverk är obemannade. Det förekommer underhållsverksamhet under begränsad tid men till största delen har ställverken ingen personal på plats. Många anläggningar ligger också långt från tätbebyggt område vilket medför långa insatstider för räddningstjänsten och ansvarig personal. Vår utgångspunkt är därför att föreslå åtgärder som ger minsta möjliga stilleståndstid vid brand eller incidenter som kan leda till brand. Det är också viktigt att kunna övervaka och styra skeenden på distans. Resultatet av denna studie kan sammanfattas i följande rekommendationer. 1. Möjliggör tidig upptäckt med hjälp av högklassig detektionsutrustning. 2. Möjlighet att omedelbart identifiera problemet, från bemannad station, exempelvis via fjärrkamera. 3. Möjlighet att koppla bort problemområdet från kraftkällan efter identifierad incident. 4. Det bör finnas släcksystem som aktiveras automatiskt via detektion eller manuellt (fjärrutlösning). 5. Man bör använda släckmedel för relärum som inte skadar elektronikprodukter. 6. Täta genomföringar för att förhindra brandspridning och skadlig påverkan av brandgaser i angränsande rum. 7. Man bör utveckla släcksystem för transformatorer som kan aktiveras innan brand utbryter. 8. Möjliggöra access även i strömlöst tillstånd 9. Särskilja redundanta system 10. Viss överkapacitet på transformatorn

    Det har visat sig mycket svårt att få en tydlig bild av förekomsten av bränder eftersom de tillfrågade parterna, typiskt kraftbolag, endera inte har någon tillfredställande dokumentation över tillbud, eller har som policy att inte lämna ut den typen av uppgifter. Förbättrade rutiner för dokumentation av tillbud är en förutsättning för en långsiktig förbättring av brandskyddet. Kunskapen om bränder och explosioner i transformatorer är mycket mer begränsad än bränder i byggnader och liknande. Därför behövs ytterligare studier av de mekanismer som föregår och orsakar en transformatorexplosion. Vi föreslår ett antal forskningsprojekt i syfte att kartlägga dessa mekanismer. I förlängningen kan detta resultera i system som förhindrar eller begränsar konsekvenserna av det som idag leder till att transformatorer exploderar.

    Abstract [sv]

    220 schools. Damage and defects in school buildings SP has investigated more than 220 school buildings between 1978 and 1997, finding damage in most of them. This report describes the damage and defects that we have found in building materials, functions, building services systems and structural parts of the buildings. The report also describes mechanical and biological mechanisms that have contributed to the damage. In general, most of the buildings have exhibited several defects, with the most noticeable damage being caused by moisture. The damage has been caused by defects, but the number and diversity of these defects is striking. The report describes our experience: the text is complemented by no less than 174 figures and diagrams. There are differences between them, with more than one defect being illustrated in many of them. Many different types of faults have been found in the buildings: in general, several faults taken together have led us to the damage that we found. To some extent, the report describes where the faults have occurred: we have found faults that can be ascribed to all stages of the building and use processes, and to all parties involved. Faults have manifested themselves as faults in one or more of the building's functions or features, with the main causes being found in three functions: moisture resistance, airtightness and air handling. These functions are interdependent and can exacerbate each other. Airtightness, for example, forms an important element of moisture resistance, while the contamination (mildew etc.) caused by moisture damage can find its way into the indoor air through air leaks in the building structure (airtightness failure), powered by pressure differences established by the ventilation system (air handling), if there is an air flow from the area of moisture damage.

    Using plate thermometer measurements to calculate incident heat radiation2013In: Journal of fire sciences, ISSN 0734-9041, E-ISSN 1530-8049, Vol. 31, no 2, p. 166-177Article in journal (Refereed)
    Abstract [en]

    The plate thermometer is a device used mainly to measure temperatures in fire resistance tests according to ISO 834-1 and EN 1363-1 and to measure the so-called adiabatic surface temperature. However, it can also be used to measure incident radiant heat flux (q·″inc) as a simpler, more robust and less-expensive alternative to water-cooled heat flux meters. The accuracy of the measured q·″inc is subject to simplifications in the heat transfer analysis model and uncertainties of parameters such as convective heat transfer coefficients, emissivities and ambient gas temperatures. This study investigates the accuracy of the model itself, isolated from the uncertainties of the physical surrounding, by comparing a simple one-dimensional model to the results of finite element modelling. The so-obtained model includes a heat transfer coefficient due to heat losses of the plate thermometer, found to be KPT = 8 W/m2 K and a heat storage lumped heat capacity CPT = 4200 J/m2 K for an ISO/EN standard plate thermometer. The model is also compared to real field experiments.

    Combustion Characteristics of Municipal Solid Waste Bales2013In: Fire Technology, Vol. 51, no 1, p. 109-127Article in journal (Refereed)
    Abstract [en]

    Combustion behaviour of municipal solid waste bales is a rarely studied topic hitherto. However, there is dire need to devote research on the topic because baling as a storage methodology is getting popular among waste management companies and fire episodes in such storage sites can have devastating economic, environmental and social implications. In this study, thickness of low density polyethylene (LDPE) plastic sheets (12 layers, 6 layers and no layer) and type of ignition source (pilot ignition, thermal radiation) were investigated to see their effect on combustion behaviour of bales. In total eleven tests with a single bale in each test were performed. It has been found that the bales not wrapped with LDPE plastic sheets may pose higher hazards for adjacently stored material to catch fire as the value of maximum heat release rate observed for them was higher than those wrapped with LDPE plastic sheets. Furthermore, it has been found that LDPE plastic wrapping do not contribute significantly to the combustion of bales when exposed only to thermal radiation from an adjacent fire. However, it plays a significant role in ignition of bales in case exposed to a pilot flame ignition source. Molten LDPE plastic trapped between the adjacently stored bales was found to be another important factor influencing the combustion of bales.
