Aim: The aim of the article is to discuss, using literature on the subject, the results of scientific research and fire tests devoted to lithium-ion batteries and electric-powered vehicles, as well as various methods and techniques for extinguishing them. The presentation of these issues is important in terms of identifying the hazards present in construction objects where electric vehicles are parked and charged, as well as conducting effective and safe rescue operations during incidents involving them. Introduction: The development of electromobility, including the growing number of electric vehicles, poses new challenges for fire protection, both in the context of conducting rescue operations and the safety of parking and charging these vehicles at construction objects. Fires on lithium-ion batteries used in electric vehicles follow a different pattern than fires on conventional energy sources. This includes the causes of their origin, the course and methods of extinguishing them, as well as the dangers to those in their zone, including from the toxic products of combustion that are emitted. Consideration of the occurrence of these risks is particularly important in underground infrastructure, where firefighting is more difficult and the ability to eliminate the toxic products is limited. The article discusses the results of scientific research and fire tests involving lithium-ion batteries and electric vehicles, taking into account different methods and techniques for extinguishing them, conducted in Germany, Austria, Switzerland, Sweden, South Korea, the United States of America and Poland, among others. Methodology: The authors prepared the article based on a review and analysis of the results of scientific and experimental research, as well as on the literature. Conclusions: The growing number of electric vehicles increases the likelihood of accidents and fires involving them. This poses a challenge for rescue operations involving the vehicles mentioned above. An analysis of the literature on the subject leads to the conclusion that the catalogue of risks during rescue operations involving electric vehicles is different from that of conventionally powered vehicles. These risks require research, analysis, evaluation and validation. Keywords: fire safety, fire protection, electric vehicles, lithium-ion battery, rescue operations

Aim: Presentation of the potential of the student scientific club for road safety in Poland. Discuss the extent to which the student scientific club in its research activities supports and implements the concepts of identifying road safety risks and submits proposals for improving its condition and related processes. Project and methods: In the research on the visibility of vulnerable traffic participants, a theoretical method – NUR threat analysis – was used to define the research problem.A research problem was formulated in the form of a question: to what extent and under what conditions does NUR visibility affect their safety? Visibility tests were conducted in real conditions after dusk. The following recording devices were used to study the movement parameters of modern means of transportation (bicycles and electric scooters): a Gopro camera, a Sony IV RX10 camera (which realizes 4D recording), a drone with a vision camera, and a Brake Tester retarder. Results: The study of the visibility of vulnerable traffic participants from the perspective of the driver presents parameters for the visibility of pedestrians and cyclists in conditions after dusk. Participants (students) in the visibility study were made aware of the issue of visibility, and therefore the safety of the traffic participant in the situation of illuminated vehicle (bicycle) and without lighting, as well as a pedestrian on the road without a reflective element. They formulated the conclusion that seeing does not mean being seen.The result of the single-track motion tests was that the Brake Tester Model LWS -2/MC retarder, after the performance test, does not provide a measurement of the single-track motion parameters. This is an important practical finding from the research, as vehicle inspection stations are equipped with this device. The acceleration and deceleration values of the bicycle and electric scooter were determined Conclusions: The research activities of the students of the scientific club in question not only make them aware of the risk factors of becoming a victim of an accident as a vulnerable traffic participant, but also allow them to deepen their knowledge, broaden their cognitive perspectives and supplement their skills through practical activities, for example, in the area of NUR visibility determinants or the characteristics of powered vehicles. The transfer of the results of the conducted research is carried out through the participation of students in seminars and scientific conferences, as well as in journalistic activities.

Aim: This article presents key information and conclusions about hydrogen-powered motor vehicles, as well as technological equipment and technical infrastructure enabling the work of hydrogen fuel cells in the context of their fire safety, particularly the conduct of rescue operations. The authors’ main areas of consideration are the challenges for emergency services and the possible risks associated with the development and increasingly widespread and varied use of these technologies. Introduction: We are currently in the midst of the biggest energy crisis since the end of World War II. Therefore, the world’s leading economies are taking steps to intensify the production of alternative fuels – including hydrogen – and thus reduce the extraction of fossil fuels. One area of consideration and challenge related to increased extraction, processing and use of hydrogen is safety, particularly fire safety. In this regard, a major challenge is the knowledge, skills, equipment and facilities for rescue operations. Methodology: Based on a review and analysis of literature on the subject and available research results, key information, conclusions and recommendations directed to emergency services conducting operations during accidents and fires involving fuel cells were developed. Taken into account are the specific properties of hydrogen and the need to store it under high pressure. The article reviews the current state of knowledge regarding hazards and how to deal with them when conducting rescue operations during incidents involving hydrogen-powered vehicles. Conclusions: The development of this and other technologies, as well as the use of new alternative fuels, along with the increase in the number of vehicles powered in this way, will undoubtedly result in numerous and varied challenges for fire protection in the near future, including the need for rescue operations. These changes require systemic preparation and improvement of both the knowledge, skills of the rescuers and their equipment. Therefore, it is urgently necessary to work on the preparation/adaptation of appropriate education, training and professional development programs and teaching materials. It is necessary also to clarify the technical requirements for equipment for storing and supplying hydrogen to vehicles for example passenger vehicles and technical equipment in plants such as forklifts or generators for providing electricity in emergency situations. Work on these regulations is currently underway. Keywords: hydrogen drives, fire safety, rescue operations, rescue card

Aim: The aim of the research was to demonstrate that the use of low-emission carbon fuels (obtained using the initial thermal conversion of coal feedstock) in residential heating also makes it possible to reduce mercury emissions from small-scale coal-fired boilers. Project and methods: The publication presents the results of mercury emission tests conducted using five different small-scale coal-fired boilers and five different coal fuels. The research was carried out under laboratory conditions, but also using heating devices of residential users. They covered a wide range of operational parameters, both energy and emission. The flux of coal fuels burned ranged from 2 to 12.2 kg/h, with an equally wide range of boiler efficiencies obtained – 67.6–88.5%. Results: The test results presented in the article show that the amount of emissions of pollutants limited by the criteria of the PN-EN 303-5+A1:2023-05 standard and the ecodesign, namely carbon monoxide, nitrogen oxides, dust and organic substances, depends mainly on the design and operating conditions of the device in which the specific solid fuel is burned. There is a group of pollutants emitted into the atmosphere, for which the amount of emissions depends primarily on the quality of the fuel burned. These pollutants include sulphur oxides and mercury, whose emissions depend primarily on the combustible sulphur and mercury content of the fuel being burned. Conclusions: Experimental studies were carried out to verify what portion of Hg contained in coal during its combustion in domestic boilers with manual and automatic fuel feeding remains bound in bottom ash, and what is emitted into the atmosphere. The content of Hg in bottom ash, regardless of the boiler and fuel used, was at a similar low level, reaching a maximum of about 6% of Hg initially contained in the fuel. As studies have shown, more than 94% of mercury contained in coal fuels burned in small-scale coal-fired boilers is emitted into the atmosphere, contributing significantly to the deterioration of the environment. Replacing traditional coal with low-emission carbon fuels (e.g., such as BC fuel) would significantly reduce mercury emissions from small-scale coalfired boilers, by up to 90% compared to current emissions. Setting a legal requirement for the permissible level of mercury content in coal fuels used in domestic boilers, for example, at a maximum value of 0.05 mg/kg, would reduce mercury emissions from these devices by at least half. Keywords: mercury emission, small-scale coal-fired boilers, low-emission carbon fuel

Aim: The aim of the article is to present the legal aspects of the use of new technologies. Accelerating the progress of civilization through the rapid development of technology is a challenge for both the legislator and entities who, when applying the law, interpret imperfect regulations or have to deal with the lack of regulations on a daily basis. In this publication, the author discusses legal aspects related to the development and implementation of new technologies and answers the question whether the applicable regulations combine the intentions of the creators of the regulations with social and economic needs. Introduction: The essence of all development is the improvement and expansion of human and technological capabilities and potential. Civilizational development is a system of interconnected vessels based on mutual social, cultural and technological interdependencies, and all these spheres of public life are inextricably linked with legal regulations. Without elementary knowledge of regulations, it would be difficult to make rational decisions regarding everyday life, therefore legal standards should include solutions adequate to the needs of citizens and the economy. In case of new technologies, which are subject to continuous and dynamic changes, the traditional norm-setting model known as hard law does not fully achieve its goals, and what is more, the applicable law does not keep up with the development of new technologies. Methodology: he article describes the current state of knowledge in the field of selected aspects of new technology law. The work uses theoretical research methods, including the analysis of applicable regulations and the literature and views of the doctrine, as well as the results of the research work of the author of the publication. Conclusions: Current legal regulations do not keep up with new technologies. The legislative process itself is complicated and very long. The introduction of new regulations and legislative changes requires, among others, inter-ministerial and social arrangements, work in Sejm and Senate committees, voting in Parliament, and finally the signature of the President of the Republic of Poland. The above-mentioned legal activities take time, and new technologies mean variability and dynamism – a constant fight against time. The development of technology is certainly a new challenge for legislators, for whom cooperation with the scientific community and representatives of various technological industries is an opportunity to create regulations that support rather than limit the development of 21st century technologies.

Aim: The main objectives of this article are to characterise chemical hazards and to identify the factors (circumstances) affecting the effectiveness of responses to them, the cooperation of rescue units and the local community. The article details the methods and principles of rescue operations undertaken when various hazards are present. Introduction: With the increasing chemicalisation of the economy, at the same time indispensable in people’s daily lives, the associated chemical and environmental risks are increasing. The article presents their typology based on the sources of potential incidents. The categorisation was narrowed down to hazards caused by industrial plants using chemicals and their mixtures and transport units transporting dangerous goods. The typology also includes references to selected organisational elements of rescue and firefighting operations affecting their effectiveness. Project and methods: W związku z realizacją celu pracy analizie poddana została literatura z zakresu badanego problemu, a także obowiązujące akty prawne dotyczące ochrony środowiska, przewozu materiałów niebezpiecznych oraz właściwości substancji chemicznych i ich mieszanin. W badaniach wykorzystano również sondaż diagnostyczny z ankietą, obserwację systemową oraz doświadczenie własne z bieżącej organizacji ćwiczeń WPOR, ZPOR w ZDR we współdziałaniu z PSP. W celu zgromadzenia danych wykorzystano materiały publikowane przez Komendę Główną Państwowej Straży Pożarnej. Dokonano analizy możliwych zdarzeń awaryjnych z udziałem czynników chemicznych stwarzających potencjalne zagrożenie dla życia ludzkiego, mienia oraz środowiska naturalnego. Methodology: The typology also includes references to selected organisational elements of rescue and firefighting operations affecting their effectiveness. The research also used a diagnostic survey with a questionnaire, system observation and own experience from the current organisation of WPOR, ZPOR exercises in ZDR in cooperation with PSP. Materials published by the Headquarters of the National Fire Service were used to collect the data. An analysis of possible emergency events involving chemical agents posing a potential threat to human life, property and the environment was carried out. Results: The essence of actions in the context of chemical rescue is to minimise the hazard, to establish the location of the source of the emission in a short time and to stop the releasing chemical substance. These elements are influenced by the even distribution of forces and resources across the country. Recognition of chemical emissions is also an important element, which will be facilitated by the participation of a representative of the engineering and technical team representing the plant. On the other hand, an important step in recognising the threat will be the implementation by SGRChem – in all provinces – of readiness level C on conducting imaging reconnaissance using advanced technical means.

The research also used a diagnostic survey with a questionnaire, system observation and own experience from the current organisation of WPOR, ZPOR exercises in ZDR in cooperation with PSP. Materials published by the Headquarters of the National Fire Service were used to collect the data. An analysis of possible emergency events involving chemical agents posing a potential threat to human life, property and the environment was carried out. Results: The essence of actions in the context of chemical rescue is to minimise the hazard, to establish the location of the source of the emission in a short time and to stop the releasing chemical substance. These elements are influenced by the even distribution of forces and resources across the country. Recognition of chemical emissions is also an important element, which will be facilitated by the participation of a representative of the engineering and technical team representing the plant. On the other hand, an important step in recognising the threat will be the implementation by SGRChem – in all provinces – of readiness level C on conducting imaging reconnaissance using advanced technical means.

Aim: The purpose of this article is to review information on firefighting hoses in terms of their division and the materials used in their production, and to determine if and how external factors affect their strength and durability. Introduction: Firefighting hoses are one of the most important products of technical equipment of Fire Protection Units. Since they are an indispensable element during rescue and firefighting operations, conducting research on the strength of fire hoses is needed and extremely important from the point of view of fire protection. Project and methods: Technological advances in the area of using various types of materials for fire hoses over time have had (and continue to have) a significant impact on the undertaking of rescue and firefighting operations, the speed with which these operations are carried out, as well as their effectiveness. Therefore, at the beginning of the article, a historical outline of the fire hoses used for firefighting in various countries around the world over the years was made. In the following part of the article, the influence of external factors on the adhesive strength of firefighting hoses used in fire protection units in Poland was analysed. The effect of exposure to a 3% foam solution of a fire extinguishing agent on hose tape samples placed in this solution was tested, depending on the time of direct contact of the samples with this agent. The effect of UV exposure (under wetting and drying conditions) on the hose tape samples was also studied, with time intervals of different lengths. Results: When testing the exposure of the hose tape samples to UV light (for 90 minutes, at 38 ± 3°C, without water spray, followed by water exposure for 30 minutes, at 50 ± 10% humidity), decreasing trends were observed for the average values of delamination strengths. Tests were also made on a series of samples exposed to a 3% solution of aqueous foam extinguishing agent on the hose tape, both externally and internally. Declining trends were observed for the mean values of adhesive strengths (after 3 and 6 weeks). The impact of factors such as exposure to UV radiation, as well as the impact of the foam extinguishing agent solution negatively affects the hose tape, reducing its strength. The article was prepared on the basis of the authors’ own research results, as well as available sources, both national and foreign, based on the available literature on the raised issues.

Aim: The aim of the article is to discuss issues related to the functioning of the current Regulation of the European Parliament and of the Council (EU) No. 305/2011 establishing harmonized conditions for the marketing of construction products and the problems identified in this regard, as well as to discuss the assumptions of the proposal of the European regulation for construction products in the harmonized area. This article analyses and indicates the links of the proposal in question to the “European Green Deal” manifested in its inclusion of the assessment and communication of information on the environmental performance of construction products and the promotion of the circulation of construction products. Introduction: The area of conformity assessment of construction products in the EU is currently regulated by the Regulation 305/2011. Its main objective was to improve the functioning of the single market and improve the free movement of construction products in the EU by establishing harmonized conditions for their marketing. In practice, this meant allowing construction products to be legally marketed in one member state. However, the European Commission, after its analysis, identified some shortcomings in its implementation, which required further analysis and discussion. As a consequence, a draft of a new regulation establishing harmonized conditions for the marketing of construction products, amending Regulation (EU) 2019/1020 and repealing Regulation (EU) 305/2011 was developed to address a significant number of issues related to standardization, simplification for micro-enterprises, market surveillance and the enforcement of regulations. Methodology: The article uses theoretical research methods, including an analysis of the EC’s report on the ongoing analyses of Regulation 305/2011 and reports from entities directly involved in the opinion of the proposed regulation. The publication also includes the authors’ own formal and substantive interpretation of selected passages of the proposed regulation, which establishes harmonized conditions for the marketing of construction products. Conclusions: The proposal of the new regulation has both strengths and opportunities from the revision, as well as weaknesses and threats, or poses new challenges. Identifying the problems hindering the functioning of the single market for construction products, the EC pointed to two general goals of the CPR revision, i.e. to create a smoothly functioning single market for construction products and to contribute to the goals of green and digital transformation. The implementation of measures resulting from the entry into force of the new regulation will only show in practice whether the changes introduced have had the intended effect.

Aim: The purpose of the article is to present the hypothesis that the use of discrepancies in audiovisual materials can significantly increase the effectiveness of detecting various types of deepfake and related threats. In order to verify this hypothesis, the authors proposed a new method that reveals inconsistencies in both multiple modalities simultaneously and within individual modalities separately, enabling them to effectively distinguish between authentic and altered public speaking videos. Project and methods: The proposed approach is to integrate audio and visual signals in a so-called fine-grained manner, and then carry out binary classification processes based on calculated adjustments to the classification results of each modality. The method has been tested using various network architectures, in particular Capsule networks – for deep anomaly detection and Swin Transformer – for image classification. Pre-processing included frame extraction and face detection using the MTCNN algorithm, as well as conversion of audio to mel spectrograms to better reflect human auditory perception. The proposed technique was tested on multimodal deepfake datasets, namely FakeAVCeleb and TMC, along with a custom dataset containing 4,700 recordings. The method has shown high performance in identifying deepfake threats in various test scenarios. Results: The method proposed by the authors achieved better AUC and accuracy compared to other reference methods, confirming its effectiveness in the analysis of multimodal artefacts. The test results confirm that it is effective in detecting modified videos in a variety of test scenarios which can be considered an advance over existing deepfake detection techniques. The results highlight the adaptability of the method in various architectures of feature extraction networks. Conclusions: The presented method of audiovisual deepfake detection uses fine inconsistencies of multimodal features to distinguish whether the material is authentic or synthetic. It is distinguished by its ability to point out inconsistencies in different types of deepfakes and, within each individual modality, can effectively distinguish authentic content from manipulated counterparts. The adaptability has been confirmed by the successful application of the method in various feature extraction network architectures. Moreover, its effectiveness has been proven in rigorous tests on two different audiovisual deepfake datasets.

Aim: The aim of the research was to verify the assumptions regarding the need to unify and standardize the design of tank vehicles in order to make it easier for rescuers from specialized chemical-ecological rescue groups (SRGChem) to make the right decisions at the scene. Ultimately, such unification is expected to allow the safe elimination of the threat by improving the rescue efforts of the groups in question. To carry it out, it is necessary to analyse rescue operations and draw conclusions, which should be made available to the manufacturers of tank vehicles, carriers and SGRchem rescuers. Project and methods: In the first stage of consideration, an analysis of the literature was carried out, followed by a survey of the rescuers who are members of SRGChem in order to find out their opinions on the unification of the construction of tank vehicles. Questions included emergency unloading valves. Interviews were also conducted with experts familiar with the issues of the subject in question, in particular practitioners who perform command functions in the SGRchem on a daily basis. Results: A survey of emergency responders from specialized chemical and environmental rescue groups shows that the vast majority of this group sees a significant problem arising from the varied design of tank vehicles for transporting hazardous substances. An overwhelming number of respondents indicated that unification of the construction of tank vehicles transporting hazardous substances is feasible, but requires a lot of discussions with the manufacturers in terms of seeking new solutions, i.e., insurance relief for tank vehicles that would be certified for unified construction. Conclusions: The transportation of hazardous materials is a complex process that requires specialized knowledge. The organization of transport in accordance with current safety regulations and standards ensures not only the minimization of risks arising from the transport of hazardous materials, but also its full efficiency. It is important to remember that every participant in the transport of dangerous goods has certain responsibilities. The greatest scope is imposed on the carrier and the shipper. At the same time, it is necessary to pay attention to an indispensable element of transport safety – that is, training, which should be carried out for all employees who come into contact with dangerous goods. All these considerations lead to the conclusion that unification of the construction of tank vehicles would have a significant impact on improving the safety of transport and the effectiveness of ongoing rescue operations.
