Introduction: Unmanned aerial vehicles (UAVs) are more often and more boldly used by various uniformed formations, including pilots of the State Fire Service and Volunteer Fire Brigades. Currently, they are used to perform recognition of situations and coordination of activities with the use of RGB and thermal imaging cameras. There are also other applications of UAV, including firefighting, but at the moment they are only conceptual solutions, as they have not been tested during an actual firefighting operation. According to the authors, a drone is currently only a carrier of additional devices and its functionality during the operation depends largely on certainty and reliability of a given UAV structure, as well as on the type and quality of the elements and sensors mounted on it. Methodology: A review of literature and press reports, as well as the authors’ experience in working with UAVs and the results of their research were used to analyse the topic. Conclusions: Indicating a set of key parameters for the UAVs used by fire brigade users is only possible to define its application. Therefore, in this study, the authors presented the most common use of unmanned aerial vehicles, for which key parameters were indicated and the impact of these factors on the obtained results of drones was described. Due to the frequent neglect of camera operation and the importance of their parameters, the authors described the most frequently set parameters of photographs and their impact on the final result, which is of key importance for the usefulness of the collected material.","PeriodicalId":34374,"journal":{"name":"Safety Fire Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41436100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: People with disabilities are a group that requires special consideration when planning evacuation from public utility facilities, because many of these people – depending on the type and degree of their dysfunction – will not be able to evacuate from the danger zone on their own. The inspection carried out in 2019 by the Delegation of the Supreme Audit Office in Poznań confirmed the need to adapt the applicable legal regulations in this regard (in practice, fire safety instructions, evacuation plans, staff training and equipping facilities with adequate equipment supporting the evacuation of people with disabilities) [1]. In addition to legal and technological aspects, a very important factor in the effective evacuation of disabled people are organizational solutions adopted in a given facility, which should take into account the individual specificity (cubature) and functions of a given facility. Methodology: As part of the research process, theoretical research was used, such as: analysis of literature and legal documents, synthesis, general- ization, inference, comparison and analogy. During the research, national and foreign sources (from the United States and Great Britain) were analyzed. The selection of individual countries was guided by the level of development of the solutions adopted in these countries dedicated to supporting the evacuation of disabled people in a situation of threat to their life or health, as well as the availability of data sources. Conclusions: The presented analysis of the conditions for the evacuation of people with disabilities from public utility buildings shows the challenges that both the legislator and managers of facilities in the country face in this area, as well as the emergency services. The latter – similarly to people with disabilities – are the systemic beneficiaries of the desired changes in the area of law and tactics of rescue operations, from the moment of alerting about an event in the facility where there are people who are unable to evacuate themselves. Introducing good practices, verified in other countries, into common application, should significantly improve rescue operations. The expected effect will be to shorten the time of providing help to all people unable to evacuate themselves in an emergency – regardless of their number, as well as the type and specificity of the public facility in which the life or health threatening situation occurred.

Roguski, Dorota Szułczyńska","doi":"10.12845/sft.57.1.2021.7","DOIUrl":"https://doi.org/10.12845/sft.57.1.2021.7","url":null,"abstract":"Aim: The aim of the article is to present examples of rescue and firefighting activities carried out by PSP / national rescue and firefighting system (KSRG) with the use of innovative techniques and technologies resulting from the research and development projects carried out by teams of contractors, which included CNBOP-PIB as a leader or member of the consortium. In practice, the implementation of the obtained results allows for the actual and formal safety of firefighters-rescuers and other participants in rescue and firefighting operations, which is one of the basic duties of research and development units operating in the field of broadly understood fire protection, civil protection and crisis management. Introduction: Achieving the above goal is possible through the use of innovative techniques and technologies in rescue and firefighting operations, which allow reducing the risk of accidents and failures. Due to rational technical solutions, it is also possible to limit or even completely eliminate overloads of the osteoarticular system. The planned effect, which is to increase the safety level of rescue and firefighting operations, can also be achieved with the use of organizational and technical methods resulting from the selection of optimal methodologies, including those in logistics activities. Methodology: The article presents the possibilities of using products created as a result of the implementation of projects financed by the National Centre for Research and Development (NCBiR) related to the improvement of activity management and the use of innovative design solutions for equipment used in the planned activities. The considerations were based on the results of development activities carried out by consortia in which CNBOP-PIB participated. Summary: In literature, innovation is the implementation of a new or significantly improved product (or service), process, new marketing method or a new method of organization in the field of business practices, workplace organization or relations with the environment. Products (and services), processes and methods (technical, organizational and marketing) can be called innovations if they are new or significantly improved, at least from the point of view of rescue and firefighting activities carried out by PSP/KSRG. Conclusions: Effective use of the results of projects financed by NCBiR is one of the fastest ways to implement organizational and technical innovations in system activities. According to the authors, in order to increase the rational use of funds allocated to the implementation of research and development projects, a more active participation of the operator is recommended (in terms of content).

Musiał","doi":"10.12845/sft.58.2.2021.11","DOIUrl":"https://doi.org/10.12845/sft.58.2.2021.11","url":null,"abstract":"Purpose: The aim of the article was to analyze motorcycle accidents in Poland on the basis of statistical data from the Polish Police Headquarters from 2019. The author presents the collected data in the form of charts, broken down by causes, the number of events in individual months, and the age of the perpetrators, injured and victims. The work also deals with the issue of dealing with victims of motorcycle accidents as part of first aid and rescue. Introduction: Every year, the number of casualties on Polish roads is increasing. Accidents affect all forms of transport and communication. Modern technologies used in the production of motor vehicles, a number of forms of improving their skills available to drivers offered by training entities and the improving infrastructure of roads in the country predispose to increased traffic on Polish roads. Drivers often lose control of their vehicles, forgetting about the potential dangers of recklessness and irresponsibility. Various types of traffic incidents involving these vehicles then take place. The chances of motorcyclists during traffic accidents, despite the security measures used in helmets and protective clothing, are small. Methodology: The main research tool used during the work on the article was the analysis of data contained in the documentation. The data presented in this study constitute the material entitled Road accidents in Poland in 2019 provided by the General Police Headquarters (KGP) Road Traffic Office. The author has made a statistical analysis of the above-mentioned data to visualize road accidents involving motorcyclists and their consequences. The events in which a motorcyclist was injured and the most common causes of accidents caused by motorcyclists, the age of the perpetrators of accidents – motorcyclists, as well as fatalities and injuries in these road accidents are presented. Conclusions: In 2019, motorcyclists made up a large group of people who died or were seriously injured in road accidents. The number of traffic accidents and the number of killed motorcyclists is greater than 2018. Data analysis allowed to define the most common causes of accidents involving motorcyclists caused by drivers of other vehicles. These include: failure to give right-of-way and incorrect behavior on the road while driving, such as turning, changing lanes or overtaking. On the other hand, the most common causes of accidents caused by motorcyclists are: excessive speed, incorrect overtaking, no safe distance from other vehicles, failure to give right-of-way.

On the other hand, the utilitarian goal was to present the improvement of the organization of documenting a mass incident with the use of drones and photogrammetry tools. Design and methods: As part of the exercise consisting of a simulation of a communication disaster, the activities were documented using the func - tionality of unmanned aerial vehicles which interact with an IT system (Pix4D application). The characteristic drone models which can be used in the monitoring of a disaster site were presented. The discussed research approach describes the methods used to perform drone flights and to what extent the photogrammetric method of processing digital images obtained from drones was used. The issue of field measurements (control points, control lines), the purpose of which was to determine the accuracy of mapping and matching to the coordinate system, was discussed. Results: As part of the research, images were captured and taken with the use of UAVs and IT systems, which were collated and compared with the results of measurements from the visual inspection of the disaster site, performed in a traditional manner by the representatives of the procedural entity. A comparative analysis of the collected research material leading to a comparison of the work results captured by means of the traditional procedural forms with the methods and techniques of modern technologies (drone with the Pix4D Cloud application) allows for the following conclusions to be drawn. For short measuring sections (up to 15 meters), the measurement accuracy of the two methods differs by about 1.5%. For longer measuring sections (up to 100 m), the measurement error is approx. 2.3%. Conclusions: In case of the UAV method and the application Pix4D Cloud, the sources of measurement errors should be seen in the accuracy of rendering of the details of the model (the quality of imaging) and the ability to use this application. On the other hand, when using the police method, in which the measurement trolley is the measuring tool, the sources of error should be seen in the uneven terrain, the obstacles in the terrain, and the measurement error of the tool itself (the trolley). The innovation of the project to use UAVs certainly gains importance especially in a terrain with limited accessibility, i.e. in hilly and mountainous terrain, at road intersections or forks.

Definitions of evacuation are different in many standards and publications in the field of fire safety engineering. The introduction of a unified version of the definition will allow for a precise description of this process. The diversity of its forms and types in the literature on the subject requires the introduction of an appropriate classification. This will allow for systematization of various forms of evacuation and conducting more precise research on individual types of the evacuation process. Introduction: The evacuation process takes into account the possibility of moving not only people, but also animals and property from a place of danger to a currently safe place. It is a process that does not always take place in an organized or orderly way, and its effect is to leave the place of danger by all people. The complexity of the evacuation process allows it to be divided due to various forms, ways of conducting it, or objects subject to evacuation. In the literature on the subject, many definitions of various forms of evacuation have been formed, i.e. general, phase, organized, self-evacuation, indepen- dent, rescue, primary, gradual, selective, sequential, full, preventive, partial, successful, total, successful, successful, secondary, primary, intervention, managed, directed, unmanaged, I degree, II degree, III degree, etc. Methodology: The authors reviewed the available definitions of the concept of evacuation and proposed a new definition to describe the process in more general terms. In addition, the authors conducted a review of the forms of evacuation and its classification occurring in scientific publications within the national scope. As a result of the detailed analysis, a preliminary classification of individual determinations of the evacuation process was made. Conclusions: The concept of evacuation has a much broader meaning than the current definitions of this process. The analysis shows that evacuation should be defined as a process of moving people, animals or property from a place of danger to a place currently safe. For the purposes of this article, a total of more than 25 evacuation process determinations have been identified, which have been classified into 12 categories. Progress in many areas, i.e. construction, development of transport and urban infrastructure and the occurrence of public demonstrations/events, affects the need to verify existing definitions for the needs of new conditions. The publication aims to draw attention to the need to introduce a systematic analysis of the classification of the evacuation process. Such classification will allow for the proper identification of all kinds of variables that have different effects on different forms of this process. The introduction of such a division will allow the use of appropriate measures, tools and procedures to ensure an adequate level of human saf","PeriodicalId":34374,"journal":{"name":"Safety Fire Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66333618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rabajczyk, Grzegorz Rabajczyk","doi":"10.12845/sft.58.2.2021.1","DOIUrl":"https://doi.org/10.12845/sft.58.2.2021.1","url":null,"abstract":"Aim: The article presents information on the issue of CO2 emission (called greenhouse gas) from the energy sector, along with tools enabling the deter- mination of CO2 emissivity used to manage this process and the directions of actions taken to minimize the negative impact on the climate. Introduction: CO2 is one of the substances essential for the functioning of life on Earth. On one hand, it is an important element of the carbon cycle in nature, being the basis for the synthesis of carbohydrates. On the other hand, it belongs to the group of greenhouse gases responsible for the climate change – and for this reason, it must be subject to constant control. Due to this fact, appropriate measures are taken, including changes in law, in the scope of emission, as well as the introduction of modern technological solutions aimed at monitoring and reducing CO2 emission. Activities undertaken in the area of energy, the branch of the economy generating the largest amounts of anthropogenic CO2, accounting for 41% of global emissions of this gas, are of significant importance [1]. The developed tools, allowing to calculate the amount of carbon dioxide emissions, expressed by emission indicators, allow for the assessment of the activities undertaken both in terms of ecology and economy. Methodology: The article was prepared on the basis of a review of selected literature, and reports as well as applicable legal requirements in the field of the discussed subject. Conclusions: The implemented measures aimed at the application of emission indicators in the area of energy allowed for the definition of forecasts and the determination of the directions of activities, in order to reduce the emission of CO2. The gradual implementation of new technological solutions, enabling energy production based on biomass or other renewable energy sources, allows for the reduction of the emission of this gas. However, given the constantly increasing energy demand, it is a slow process which is not sufficient to stop the observed changes. Therefore, it is necessary to take further steps, to develop more reliable and homogeneous tools that would make it possible to compare the results regardless of the place of emission or the type of fuel used. However, it should be noted that it is necessary to cover all stages of the construction and operation of the energy sector with the measures mentioned above, which generate CO2 emission, and not only the combustion process itself.

Wolny","doi":"10.12845/sft.58.2.2021.7","DOIUrl":"https://doi.org/10.12845/sft.58.2.2021.7","url":null,"abstract":"Aim: This article attempts to present the issues related to the search for alternatives to energy resources in all sectors of the economy. The direction of the search is to choose “green energy” (in this case hydrogen), which, due to its potential wide application, is already beginning to be treated as an instrument of carbon neutrality. Most EU countries have agreed that they will be carbon-neutral by 2050, which should result in the reduction of greenhouse gas emissions to the atmosphere by around 95% compared to the beginning of the gas emissions calculation in 1990. However, achieving emission neutrality will require a far-reaching elimination of emissions not only in the power sector, but also in other sectors (including industry, transport and heating). These areas still rely on emission fossil fuels (coal, crude oil and natural gas), which cannot be directly replaced with electricity from RES. Introduction: Hydrogen is not a source of energy, but it is a very effective carrier. Although it is practically not in the free state, it is very often found in the form of chemical compounds such as CH4 (methane) or H2O (water). In order to extract the energy it contains, it must be isolated from the molecules it is composed of. Hydrogen can be transported via gas pipelines (gaseous) or tankers (liquefied). It is currently used in the petrochemical industry, in - cluding for oil refining and chemical industry for the production of fertilizers, ammonia or methanol. Recently, hydrogen has become a topic that is often discussed in the public space in the context of climate protection (and thus decarbonisation of the economy). This fuel is credited with extraordinary potential and applicability in so many areas that it should be widely regarded as oil of the 21st century and a key element of the new energy policy. Moreover, the investment in hydrogen should support sustainable growth and job creation, which will be critical when recovering from the COVID-19 pandemic. Methodology: The article provides an overview of research questions and the most recent results of considerations. It presents a multidimensional and interdisciplinary analysis of the suitability of alternative fuels and the implementation of the related projects. The analysis of the topic was based on, among others, on the project of the Polish Hydrogen Strategy, which is important for the further development of research topics and cooperation in this field. Conclusions: For the energy sector that processes available forms of energy, hydrogen is probably a good choice for the future. It can be an alternative to natural gas in providing backup capacity for renewable energy sources that produce energy dependent on weather conditions (i.e. sun and wind). Hy- drogen, which has the advantage of high energy density, is also a good tool for storing renewable energy and for transmitting and distributing renewable energy over long distances.

Wyszomirska","doi":"10.12845/sft.58.2.2021.2","DOIUrl":"https://doi.org/10.12845/sft.58.2.2021.2","url":null,"abstract":"Purpose: The aim of the article is to discuss tax issues related to the settlement of subsidies for the implementation of projects in the area of\"Security and Defense\". The grant beneficiaries face numerous problems with the interpretation of the provisions of the VAT Act, which may result in serious financial consequences in the event of incorrect application of the VAT Act. This publication analyses and indicates solutions to these problems, which are most often raised by consortia, both in applications for tax interpretations and in complaints to administrative courts of both instances. Introduction: Among the important forms of activity for the security and defence of the state, a special role is played by scientific and research and development projects, which not only increase the potential of scientific and industrial entities, but also create Polish know-how in the field of critical technologies in the area of \"Security and defence\". The implementation of projects financed from the state budget places on the beneficiaries the obligation of a \"regime\" method of settling public funds, both by applying the provisions on public procurement, constructing civil contracts, taking into account the fact that funds from subsidies are available, as well as performing special diligence in tax settlements with the tax authorities. Methodology: The theoretical research methods were used in the work, including the analysis of literature, judgments of common courts and the Pro - vincial and Supreme Administrative Court, as well as tax interpretations issued by the Director of the National Revenue Administration. The publication also provides an interpretation of national regulations as well as directives and case law of the Court of Justice of the European Union.

Project and methods: In many places around the world, scientists conduct tests related to the use of mechanical tactical ventilation with the use of mobile positive pressure ventilation fans. These devices are used by fire protection units, among others, for the removal of thermal decomposition products resulting from fires, posing a threat to people staying in construction facilities during events and hindering rescue operations. Achieving the expected effects through the use of mechanical tactical ventilation depends on many factors, among others, on the appropriate technical parameters and the ability to use the fan. Describing the essential features that should be characterized by the devices in question, attention in particular should be paid to: mobility, durability, reliability and effectiveness. To confirm these features, mobile fans should be tested using properly validated test methodologies. This publication presents a draft of the test program that allows to confirm the effectiveness of mobile fans, i.e. aerodynamic efficiency (flow rate), stream shape (area of the effective speed distribution), operating time, noise, weight and dimensions. Conclusions: Mobile fans used by fire protection units are an important tool supporting the effectiveness of rescue operations. However, in order for them to be used in an optimal way, it is necessary to comprehensively examine the technical parameters, and then – adequately to these parameters – to develop appropriate procedures for their use. In the context of the aforementioned testing, despite the large scientific achievements in this field, there are still areas that require improvement, with particular emphasis on standardized testing methodologies and the measurement infrastructure dedicated to them. For this reason, the authors indicated important technical and functional features that determine the effectiveness of mobile fans and recom - mended selected methods on the basis of which these features can be verified. The intention of the project is to provide rescuers with greater comfort when choosing and using the devices in question. The basis for this comfort is to be aware of the availability of equipment with confirmed functional characteristics and the possibility of referring to the developed guidelines for the proper use of fans in accordance with their parameters.
