A1 - Hofmann-Böllinghaus, Anja T1 - Small-scale studies on evacuation characteristics of pedestrians with physical, mental or age-related disabilities N2 - Evaluation of evacuation process is common separated by two phases: pre-movement and movement-phase. Individual capabilities of pedestrians have an impact on both and therefore on the time required for safe escape. In view of evaluating the evacuation process, characteristics of realistic movements of pedestrians involved are needed, but so far such data are mainly available for individuals with unrestricted evacuation capabilities only. Due to the lack of available data, parameter studies in an assisted living for people with disabilities were performed to explore the movement during evacuation. Preparation times for assistance (n=10), unimpeded walking speeds (n=34) depending on the assistance devices in the plane as well as walking speeds on stairs (n=11) were focussed. Time to prepare an assistance device for utilisation depends significantly on the kind of device type. Further on, practical experience in handling the devices for assistance has an impact on the preparation time. In contrast to the results of the preparation times, any relation on assistance devices were investigated for the unimpeded walking speed in the plane. A remarkable decrease of walking speed on stairs was observed which is independent from the utilised assistance device. The presented data improve and extend the insufficient engineering data base and raised up questions regarding the complexity of considering pedestrians movement with impairments in evacuation planning.

T1 - Fire safety of FAÇADES with polystyrene foam insulation N2 - As part of energy‐efficient renovations or for the construction of new buildings often external thermal insulation composite (ETIC) are used. In 2015, in Germany almost 37 million square meters were installed. But several fires involving ETIC systems with polystyrene foam (EPS) insulation in Germany led to an extensive discussion about fire safety of such systems. A collection initiated by the Frankfurt fire service of façade fires which include polystyrene insulation foam1 shows that more than two thirds of all reported fires started in front of buildings. In half of these fires burning waste containers were the first burning objects. Consequently, German building authorities called for tests of existing approved ETIC systems with EPS insulation in a fire Scenario representing a burning waste container. As these tests revealed weaknesses in the existing ETIC systems measures were introduced to enhance the systems. However, the recently introduced German test standard DIN 4102‐20 does not take These changes into account. The DIN test represents a fire where flames emerge an opening but is downscaled regarding the size of the fire load and therefore does not represent a fully developed fire in a room. In ETIC systems with EPS insulation, the render is an important factor for the fire performance of these systems as collapse of the render usually leads to very rapid fire development. Intermediate scale tests with ETICs specimens indicate that mechanical damages of the render weaken the System significantly. Challenges and possible measures to enhance fire safety of ETIC systems are discussed.

Nach einer eigenen Internetrecherche brennt etwa an jedem zweiten Tag ein Bus in Deutschland. Die grundlegenden Brandschutzvorschriften für Busse gehen auf die amerikanische Norm FMVSS 302 zurück, die in den 60er Jahren entwickelt wurde und ist quasi weltweit noch immer in sämtlichen nationalen und internationalen Brandschutzvorschiften wiederzufinden. Ziel der FMVSS 302 ist es vor allem, Fahrzeugbrände durch das Rauchen zu verhindern. Verschiedene Untersuchungen zeigen jedoch, dass die meisten Busbrände andere Ursachen haben und zu ca. 80 % im Motorraum entstehen. Auch das Versagen von elektrischen Komponenten ist häufiger die Brandursache. Dies geschah z.B. im Jahr 2008 bei einem schweren Busbrand in der Nähe von Hannover, bei dem sich gerade einmal 13 Passagiere selber retten konnten und 20 Menschen ihr Leben verloren. Einige Brandleichen wurden sogar noch am Sicherheitsgurt angeschnallt aufgefunden. Durch die enorme Zunahme brennbarer Kunststoffteile in Bussen entstand ein bisher unberücksichtigtes Risiko, das bei der Normentwicklung in den 1960er Jahren nicht berücksichtigt wurde. So hat sich die Brandlast seitdem etwa verzehnfacht und das toxische Potential erheblich gesteigert. Nach wenigen Minuten muss bei den Brandopfern bereits mit einem schnellen Tod durch Rauchgasvergiftungen gerechnet werden. Aufgrund der schnellen Brandentwicklung in Bussen können Passagiere in den allermeisten Fällen nicht bis zum Eintreffen der Feuerwehr warten und müssen sich selber retten. Die Zeit für die Selbstrettung muss signifikant verlängert werden, so dass auch mobilitätseingeschränkte Passagiere eine Chance zum Verlassen des Busses haben. Der Vergleich mit Brandschutzanforderungen anderer Transportsektoren (Bahn, Schiff, Flugzeug) zeigt, dass die Anforderungen dort sehr viel höher sind. Sowohl die Entflammbarkeit als auch die Wärmefreisetzung sowie die Rauchfreisetzung werden in diesen Normen begrenzt. Zudem werden Materialanforderungen hinsichtlich der Rauchgastoxizität gestellt. Im Ergebnis dieser Arbeit sollen einerseits Brandschutzempfehlungen für die zweckmäßige und zugleich wirtschaftlich vertretbare Ausstattung von Bussen im Innenbereich unterbreitet werden. Andererseits sollen auch Überarbeitungsvorschläge für Prüftests vorgestellt werden, die den Brandschutz von Kraftomnibussen sicherstellen und erstmals auch Grenzwerte für die Rauchgastoxizität beinhalten. Dazu werden neben den Brandversuchen auch numerische Simulationen mit dem Fire Dynamics Simulator (FDS, Version 5, NIST) durchgeführt, in denen verschiedene Brandszenarien mit unterschiedlichen Buskategorien simuliert werden.

The project's objective was to finalise a European approach for assessing the fire performance of façades under medium and large fire exposure conditions. The national standards BS 8414‐1:2020/BS 8414‐2:2020 and DIN 4102‐20:2017 served as the foundation for developing the new assessment method. As part of the project, a theoretical round robin, initial testing activities and a large‐scale experimental round robin were carried out. The theoretical round robin aimed to examine how different laboratories interpreted the preliminary assessment method. Subsequently, the initial testing phase explored the design of the fire source, combustion chamber and secondary opening. The experimental round robin involved testing four façade systems across three laboratories using the assessment method documents, resulting in 12 tests for medium‐scale and 12 for large‐scale exposure—24 tests in total. These tests provided data to develop a calibration scheme and define appropriate performance criteria for classification. In this paper, the representatives of the project consortium summarise the research process and outline the proposed testing and evaluation methodology, which is intended to form the foundation of a future European testing standard for façades. The article also highlights the need for further research to establish rules for extended application of test results.

A project consortium from five countries (Sweden, UK, France, Germany and Hungary) applied to the call for tender and was contracted to develop a European approach to assess the fire performance of façades. 24 sub-contractors and 14 stakeholder entities were part of the project. The objective of the European project was to address a request from the Standing Committee of Construction (SCC) to provide EC Member States regulators with a means to regulate the fire performance of façade systems based on a European approach agreed by SCC. In addressing this objective, the project team was asked to consider a number of issues which are presented and discussed.

These data are typically based to young and fit populations. However, the movement abilities of occupants who might be involved in evacuations are becoming more variable—with the building populations of today typically including increasing numbers of individuals: with impairments or who are otherwise elderly or generally less mobile. Thus, there will be an increasing proportion of building occupants with reduced ability to egress. For safe evacuation, there is therefore a need to provide valid Engineering egress data considering pedestrians with disabilities. Gwynne and Boyce recently compiled a series of data sets related to the evacuation process to support practitioner activities in the chapter Engineering Data in the SFPE Handbook of Fire Protection Engineering. This paper supplements these data sets by providing information on and presenting data obtained from additional research related to the premovement and horizontal movement of participants with physical-, cognitive-, or age-related disabilities. The aim is to provide an overview of currently available data sets related to, and key factors affecting the egress performance of, mixed ability populations which could be used to guide fire safety engineering decisions in the context of building design.

Particularly, the capacity estimation is a crucial performance criterion for assessment of pedestrians' safety in built environments. For this reason, several studies were performed during the last decades which focus on the quantification of movement through corridors and bottlenecks. These studies were usually conducted with populations of homogeneous characteristics to reduce influencing variables and for reasons of practicability. Studies which consider heterogeneous characteristics in performance parameters are rarely available. In response and to reduce this lack of data a series of well-controlled large-scale movement studies considering pedestrians using different types of wheelchairs was carried out. As a result it is shown that the empirical relations are strongly affected by the presence of participants with visible disabilities (such as wheelchair users). We observed an adaption of the overall movement speeds to the movement speeds of participants using a wheelchair, even for low densities and free flow scenarios. Flow and movement speed are in a complex relation and do not depend on density only. In our studies, the concept of specific flow fits for the nondisabled subpopulation but it is not valid for scenario considering wheelchair users in the population.

The German research Project SiME is an interdisciplinary cooperation of university and non-university research institutions as well as medium-sized companies, which work together to develop strategies to manage such critical scenarios. In the SiME project, which is funded by the German Federal Ministry of Education and Research, evacuation characteristics of pedestrians with physical, mental or age-related disabilities are investigated to fit consisting numerical evacuation models with data. One of the major tasks of the OvGU was to set up a database of scenarios related to fire, explosion or substance releases in the working and living environment of handicapped people. Therefore, more than 463 fire Events occurring over the last decade in Germany were documented in this database and categorized by a suitable assignment of characteristics e.g. location of fire, ignition source, number of fatalities and injured. The evaluated data were the basis for carrying out a quantitative risk analysis. Thus event trees were set up for different integrative infrastructures with which occurrence probabilities for different scenarios could be calculated for each path. The extent of damage, as a quantity describing the impact, was assumed to be personal injury or death or serious injury. By a risk assessment critical Scenarios could be derived from the risk analysis.

The tests, conducted in Saxony‐Anhalt and Brandenburg, targeted regions with dry, sandy soils and extensive pine stands and aim to improve suppression strategies and wildfire research. The forest experiment was conducted on a 16 × 22 m plot with line ignition using a gasoline‐diesel mix. Fire spread was documented with drone‐based video and infrared imaging. Ninety‐six thermocouples and two gas sensors were mounted on trees, and a mobile FTIR spectrometer enabled real‐time smoke analysis. A tilled and foam‐treated strip prevented uncontrolled spread. Under stable weather conditions (23°C, light wind, low soil moisture), a consistent temperature rise and distinct combustion phases were observed. Smoldering dominated in areas with mosses, grasses, and deadwood, with intermittent flaming, limited flame heights (< 0.5 m), and substantial smoke production. Peak temperatures exceeded 500°C, and CO concentrations reached 238 ppm, though wind turbulence complicated gas sampling. The second experiment on a cut agricultural field near Nauen involved burning approximately 700 m2 using a 20 m ignition line aligned with wind direction. Drone‐based infrared monitoring captured rapid spread on the stubble surface. The results underscore the variability and measurement challenges of outdoor fires and highlight the necessity of continued large‐scale experiments to support physical and numerical wildfire modeling. These findings provide essential empirical data for evaluating vegetation‐specific burning behavior, improving sensor deployment strategies, and refining validation approaches for next‐generation wildfire spread models under central European fuel and weather conditions, and supporting decision‐making in wildfire management.

Within the research project ‘TEBRAS’ the incipient phase of fires was investigated in detail. In the course of the project, it became apparent that the definition of what exactly the incipient phase of a fire encompasses is not definite and depends on the disciplines dealing with the subject ‘fire’. Based on the results of a literature review, an inquiry under experts and laypersons as well as practical fire tests a definition for the phenomenon of the incipient fire was developed which divides it into four phases. Driving key factors for each phase are identified considering the main parameters to detect and extinguish the fire.

Based on a smart multilayer jacket around the fibre over the physical length of the FBG, magnetic fields generated by rotating machine parts, power generators or power cable can be easily detected, analysed and evaluated. Consequently, this innovative, on-line and non-contact inspection method results in an increase in quality and reliability of high-performing machine parts, devices and cables. The basic physical principle is based on a magnetostrictive multilayer system that strains the high-resolution FBG element in presence of magnetic fields. Subsequently, a fixed relationship between induced magnetic field and wavelength change of the FBG element describes the characteristic sensitivity curve. Intensive tests regarding characterisation of this magnetic field FBG sensor have been carried out and its performance has been evaluated.

Fire safety requirements for the burning rate, melting and dripping behaviour of interior materials already exist for many years. However, it remains unclear to what extent the release of smoke, combustion products and their toxicity should be limited. Therefore, a research and development project 82.0723 funded by BASt (Federal Highway Research Institute) was initiated to develop a simplified procedure for testing the toxicity and smoke development in case of fire of interior materials used in buses. The scope of the research included calculations to assess the toxicity of fire gases and the derivation of specifications for the formation of practicable limit values for smoke toxicity. Further investigations are needed to derive these limit values for smoke toxicity in order to be applicable for real fire scenarios in buses.

Individual capabilities of pedestrians have an impact on both and therefore on the time required for safe escape. In view of evaluating the evacuation process, characteristics of realistic movements of pedestrians involved are needed, but so far such data are mainly available for individuals with unrestricted evacuation capabilities only. Due to the lack of available data, parameter studies in an assisted living for people with disabilities were performed to explore the movement during evacuation. Preparation times for assistance (n = 10), unimpeded walking speeds (n = 34) depending on the assistance devices in the plane as well as walking speeds on stairs (n = 11) were focussed. Time to prepare an assistance device for utilisation depends significantly on the kind of device type. Further on, practical experience in handling the devices for assistance has an impact on the preparation time. In contrast to the results of the preparation times, any relation on assistance devices were investigated for the unimpeded walking speed in the plane. A remarkable decrease of walking speed on stairs was observed which is independent from the utilised assistance device. The presented data improve and extend the insufficient engineering data base and raised up questions regarding the complexity of considering pedestrians movement with impairments in evacuation planning.

T1 - Closing Data Gaps and Paving the Way for Pan-European Fire Safety Efforts: Part I—Overview of Current Practices for Fire Statistics N2 - The analysis of the current state of fire statistics and data collection in Europe and other countries is needed to increase awareness of how fire incidents affect buildings and to support pan-European fire prevention and fire mitigation measures. The terminology and data collected regarding fire incidents in buildings in the EU Member States were mapped to obtain meaningful datasets to determine common terminology, collection methodology, and data interpretation system. An extensive literature review showed that fire data collection systems have been instrumental in informing firefighting strategies, evidence-based planning, prevention, and educational programmes. Differences and similarities between fire data collection systems were also investigated. The amount and quality of the information in fire statistical recording systems appear to be influenced by the complexity and structure with which the data are collected. The analysis also examined the existing fire statistics in the EU Member States and a few other countries. Finally, a detailed investigation of the number of fires, fire deaths, and injuries from 2009 to 2018 in several countries was examined based on data from a report by CTIF. The trends showed differences attributable to the existing fire statistical practices in terms of terminology and data collection, and interpretation. Part II proposes a common terminology for selected fire statistical variables. The results provide relevant information regarding fire safety at the European level and should be used to guide the development of more uniform fire statistics across Europe.

T1 - Fire safety of interior materials of buses N2 - This study provides an analysis on the fire safety of passengers and the fire protection of coaches and buses. A brief review of major bus fire incidents, an overview of current regulations in Europe, and their limitations are presented. The study finds that the current small-scale fire test methods described in UN ECE Reg No. 118 need to be replaced by test methods that can assess the reaction to fire of materials when exposed to ignition sources of varying sizes. To address these shortcomings, the study proposed an expert recommendation to update the material fire safety requirements and testing for buses. Additional measures are proposed, derived from objectives and strategies applied in other transport sectors, and can be tested through existing European and international standards, which are widely used by several industries. These measures aim to extend the time with tenable conditions for a safe evacuation in case of fire, reduce the degree of damage to buses, reduce the risk for fast and excessive thermal exposure on modern energy carriers needed for a more sustainable transport sector.

The focus is particularly on regions with extensive pine forests, like in Eastern Germany. The relevance of smoke gases is well illustrated by the example of wildfires in Québec, influencing air quality in New York, in 2023. By employing a modified DIN tube furnace, a bench‐scale test set‐up, the research emphasizes the examination of smoke composition from tree species and ground cover, prioritizing gases while disregarding particles. Key smoke gases are identified as CO, CO2, SO2, HCN, C3H4O (acrolein) and CH2O (formaldehyde) and their concentrations are compared with Acute Exposure Guideline Levels (AEGL) limits. Acknowledging the limitations of AEGL usage and the problem with direct quantitative comparison of toxicant concentrations (cf. ISO 29903‐1:2020), the study highlights variations in smoke composition across different samples. The results of the studies reveal a significant disparity in CO concentration between dry and fresh pine needles. Frequently, the AEGLs of key gases are exceeded significantly. The elemental analysis of the barks indicates distinct differences in composition, reflecting in the concentrations of smoke gases. The ratio of 1 mole of substance turnover to the identified key components will be used to determine input parameters for the subsequent numerical simulation.

T1 - Modeling fire scenarios in buildings with CFD N2 - In the frame of the European harmonization, new European technical standards (Eurocodes) have been developed in recent years. Classical methods, like tables and simplified analytical procedures, as well as general engineering techniques are allowed by the Eurocodes for the fire protection design. The modeling and calculation of fire scenarios with CFD (Computational Fluid Dynamics) numerical methods is one of the general engineering methods. It is nowadays still difficult to check and evaluate the CFD results for their use as technical documents for fire safety design. Analytical engineering techniques, zone models and CFD-models have been used and compared in the present work for the prediction of the fire development in a building. To solve the conservation equation for the CFD-model, the CFD-program FDS, with the mixture fraction model, and the CFD-program FLUENT, with the one step reaction model as well as with the volumetric source term model, have been used. The combustion of polyurethane is modeled in FDS by specifying the heat release rate and the stoichiometry. For the combustion in volumetric source term model, the heat release rate and the smoke release were specified with respect to the stoichiometry. The input parameter for the one step reaction model is the pyrolysis mass flow. In the one step reaction model, the transport equations for polyurethane, H₂O, N₂, O₂, CO₂, CO and C (soot) are solved and the heat of combustion is determined from the standard formation enthalpy of all the components. In volumetric source term model, the transport equation is solved for air and smoke. FDS solves the transport equation for the mixture fraction. To model the fire development, and where no literature data was available, the required material characteristics like specific heat capacity, absorption coefficient and heat of combustion were measured. In all the investigated CFD-models the heat- and species transport equation has been solved and the absorption coefficient of soot has been considered. Furthermore, the fire development has also been investigated using zone models with the programs CFAST and MRFC. Results from analytical engineering techniques (plume calculations), which were design criteria in the past, have been used as plausibility checks for the present work. The calculation results from the investigations were compared to measurements in the same building performed by the National Institute for Standards and Technology (NIST).

T1 - Evacuation dynamics under consideration of vulnerable pedestrian groups N2 - The understanding of human behavior during evacuation processes is an important matter to improve the safety of infrastructures. In many countries, the implementation of performance based codes enables fire safety engineers to use computer based calculation tools to predict and evaluate pedestrian movement and human behavior in buildings. The models are based on experimentally obtained parameters and theoretical models. Pedestrian behavior can be influenced by the characteristics of the buildings (e.g. type of the building) as well as the characteristics of individuals and the pedestrian group. This paper shows that the approach of Required Safe Egress Time (RSET) / Available Safe Egress Time (ASET) is imprecise with regard on heterogeneous pedestrian groups, because this concept completely neglected the variability’s in individual pre-movement and movement abilities.

A collection initiated by the Frankfurt fire service of façade fires which include polystyrene insulation foam shows that especially fires which started in front of the buildings led to more severe fires of the façade than fires that started inside the buildings. In several fires the ignition source were burning waste containers. Three large scale tests which were initiated by German building ministries showed weaknesses of the existing systems when challenged by a bigger fire source in front of the façade. Since then measures have been introduced to enhance these systems and an additional test with a 200 kg wood crib in front of a large test rig has been used for approval of ETICS. However, the recently introduced German draft standard DIN E 4102-20 does not take these changes into account although real cases and the large scale tests showed that fire scenarios with a bigger ignition source as a waste container are not covered by the DIN E 4102-20. Numerical investigations show that regarding the heat flux to the area above the opening (e.g. a window) also only a fraction of real fires is covered. Additionally damaged systems have been investigated using the Single Burning Item (SBI) test with higher heat release rates of the burner. The damage significantly influenced the fire development of the specimen. Collapse of a damaged coating of an ETIC system occurred during the test and had a sudden fire growth as a result as the whole specimen was suddenly on fire. Several effects which could be seen in the intermediate scale tests correspond to observations which were made in the real cases. In Germany insulation of existing buildings is often enhanced with application of ETICS. In most cases the buildings are in use at the time when the construction takes place. At several stages of the construction process large amounts of unprotected polystyrene are stored in immediate proximity of the building and unprotected polystyrene can be in place on the façade for several weeks. As a consequence of the investigations challenges and possible measures to enhance fire safety of ETIC systems are discussed.

This designation facilitated the investigation of vegetation types, soil structure, and soil dryness. Brandenburg and Saxony-Anhalt are identified as the driest regions in Germany according to the annual mean soil moisture data. In these regions, 48% to 73% of the forests are composed of pine species. The soil profile is characterized by a relatively thin organic layer, measuring between 0.2 and 0.3 meters, underlain by sandy substrates. Consequently, surface and ground fires are more prevalent in these areas compared to other types of fires, such as crown fires. To investigate the influence of local vegetation, it goes through two aspects. One is laboratory study, the local vegetation samples were collected and tested for the thermal properties, such as activation energy, heat content and reaction kinetic of pyrolysis and dehydration. At the same time, small and medium scale combustion experiments were conducted to investigate the burning behavior. The other aspect is using the thermal properties as the input parameters for the development of numerical simulation in the computational fluid dynamics (CFD) tool. These models were then be validated with the combustion experiments, as a baseline for the further scaling up of the models, in order to investigate how the parameters influencing the fire spread in a large-scale case numerically.

The fire spread externally over the building faccade and internally along the staircase and affected all the flats above leading to two fatalities. It is estimated that the fire was discovered minutes after ignition and the fire service was called very shortly after the detection and was at the scene 9?min after the call.
