The purpose of this study was to find out problems encountered by Foskor Mine workers in Phalaborwa with the use of personal protective equipment and also to find out how these problems can be prevented or solved. A quantitative research study was done using a questionnaire as a data gathering tool on workers who are exposed to occupational injuries and illnesses and who use personal protective equipment for their protection. The findings revealed that even though workers were using personal protective equipment they still got occupational injuries and illnesses. They also had problems with their protective equipment like incompatible types of personal protective equipment, such as weight where heavy personal protective equipment like boots were issued and very hot or cold personal protective equipment incompatible with the temperature of the environment. Some personal protective equipment like gloves were of a wrong size and caused allergy. In some instances unavailability of or unsuitable personal protective equipment posed challenges to these workers. / Health Studies / M. A. (Health Studies)

The thesis, entitled "Analysis of safety in transport and servicing of transport facilities for the selected companies" deals with safety and work-related injuries in transportation and servicing of transport facilities. Occupational injury is caused by a set of several interacting factors. These factors are known as the main source and cause of work-related accidents, which affect the formation of accidents. The most important element in the protection of health and safety is prevention. To evaluate the risks is one of the fundamental principles of the concept of occupational health and safety policy that is enforced in all countries espousing the principles of safe enterprise. The need to protect the health of the individual is already firmly established even in the most basic legal document such as the Constitution of the Czech Republic. The aim of this work is to analyze the factors that are involved in causing accidents at work and on the basis of the analysis, to provide rules and recommendations for farms so that they serve as an aid in the elimination of induced injuries.

The diploma thesis deals with the protection of personnel in cytoreductive surgery and hyperthermic intraperitoneal chemotherapy, focusing on non-medical healthcare workers - anesthetist nurses. The aim of the work was to analyze the knowledge of anesthesia nurses in the use of personal protective equipment, the specifics of selection for the given performance, the use of an electrocautery with integrated suction, the availability of decontamination aids In case of an accident of cytotoxic substances and if the staff is afraid of their own health. The data was obtained through a questionnaire. For the research were selected anesthesia nurses working in operating theaters in selected health care facilities in the Czech Republic. The total number of respondents who participated in the research was 35. The results of the survey revealed that the staff did not find out what PPEs are recommended for this type of operation. It's either because the staff is less linguistically equipped or does not know EBN / EBP or EBM. The staff only uses those PPEs that are available to them. As a good result, 49% of respondents use an integrated electric exhaust system. With regard to the availability of decontamination aids, I have found that most of the staff does not know whether these utilities are available at...

Bakgrund: Pandemin orsakad av Covid-19 har tvingat intensivvården till stora omställningar. Som del av restriktioner för att reducera risk för smittspridning måste skyddsutrustning användas vid patientkontakt med smittad patient. Användandet av skyddsutrustning har introducerat tankar på hur den vårdande relationen mellan patient och intensivvårdssjuksköterska påverkats.  Syfte: Syftet med studien var att belysa intensivvårdssjuksköterskans upplevelse av hur arbetet i skyddsutrustning under pågående pandemi påverkat den vårdande relationen med patienten. Metod: Semistrukturerade intervjuer genomfördes med sex intensivvårdssjuksköterskor. Intervjuerna låg vidare till grund för analys enligt tolkande fenomenologisk analys (IPA).  Resultat: Fyra överordnade teman framträdde ur analysen. I temat fokus på kommunikation framkom olika sätt skyddsutrustningen påverkat kommunikationen. Upplevelsen av avskärmning framkom i temat fokus på distans där närhet uttrycktes som avgörande för en vårdande relation. I temat fokus på lidande beskrevs hur skyddsutrustningen inverkat på lindrande beröring men också att den kan orsaka lidande. Känslor av otillräcklighet i den vårdande relation och maktlöshet inför att inte förmå förändra eller påverka framkom i temat fokus på känslor.  Slutsats: Skyddsutrustningen påverkar den vårdande relationen. Skyddsutrustningen reducerar möjligheten till etablering av vårdande relation vilket riskerar minska patientens möjlighet till delaktighet. Behov föreligger av ytterligare forskning om påverkan med fokus på prevention. Ett organisatoriskt medvetande om skyddsutrustningen inverkan på den vårdande relationen kan ligga till grund för interventioner ämnade att reducera dess negativa påverkan. / Background: The pandemic caused by COVID-19 has forced the intensive care to make several adjustments. As part of restrictions to prevent spread of infection personal protective equipment (PPE) has to be used when in contact with infected patients. The use of PPE has introduced questions of its impact on the caring relationship between the patient and intensive care nurse.  Aim: The aim with this study was to illustrate the intensive care nurses experience of how working in PPE during the pandemic has affected the caring relationship with the patient.  Method: Semi- structured interviews was conducted with six intensive care nurses. The interviews served as data for an interpretative phenomenological analysis (IPA).  Results: Four superior themes emerged from the analysis. In the theme focus on communication emerged different way of which the PPE has affected communication. The experience of being shielded emerged in the theme focus on distance where closeness was expressed as essential. In the theme focus on suffering was the PPE´s impact on touch described and also its potential cause of suffering. Emotions of inadequacy in regards to the caring relationship and powerlessness in regards of not being able to change or affect emerged in the theme focus on emotions.  Conclusion: The caring relationship has been affected by the use of PPE. PPE reduces the possibility of establishing a caring relationship which endangers the patient’s active participation. There is need for further research about affect with focus on prevention. An organizational awareness regarding PPE´s effect on the caring relationship could lay the foundation for interventions supposed to reduce its negative impact.

I december 2019 rapporterades de första fallen av ett virus benämnt som covid-19 i Wuhan, Kina. Viruset sprider sig snabbt och i takt med den okontrollerade spridningen blir också trycket på sjukvården allt högre. Samtidigt som vården gör allt i sin makt för att räcka till så rapporteras det om global brist på skyddsutrustning. Tillverkningen av ett kirurgiskt munskydd, från fiber till färdig produkt, består av ett omfattande system och kräver material av specifika fibrer som framställs i avancerade processer. Att skapa ett munskydd som besitter möjligheten för återanvändning hade varit ett alternativ i syfte att minska risk för att munskydd tar slut samtidigt som engångsförbrukning minimeras. Syftet med denna studie är att studera och analysera materialval, framställning, konstruktion och krav för kirurgiska munskydd. Studien syftar också till att undersöka alternativa möjligheter till att skapa ett återanvändbart munskydd. Val av metod för insamling av material har haft sin utgångspunkt i litteraturstudier av främst vetenskaplig karaktär. Då ämnet är högaktuellt har nyhetsartiklar från betrodda dagstidningar varit av värde. Intervjuer av kvalitativ läggning genomfördes i syfte att skapa en överskådlig inblick i vårdarbetet. Ett kirurgiskt munskydd fungerar som en skyddande barriär mot överföring av smittämnen mellan personal och patient och är generellt uppbyggt i tre olika lager. Det inre lagret, mittenlagret, är tillverkat genom en process kallad nonwoven meltblown medan de två yttre lagren, det övre och det undre, tillverkas genom en process kallad nonwoven spunbond. Dessa tre lager kalendreras sedan samman och bildar själva filtermediet som därefter veckas och sys i en konverteringslinje. Munskydd är en engångsvara och slängs direkt efter användning. Nawar Kadi, som är professor på Textilhögskolan i Borås, arbetar för tillfället med ett projekt som syftar till att utveckla ett delvis tvättbart munskydd som fungerar att återanvända. I dagsläget finns många aspekter att beakta och frågor att besvara innan projektet går att förverkliga i praktiken men med rätt förutsättningar, ekonomisk stöttning och framförallt beprövade metoder med bakomliggande forskning är möjligheten till att skapa ett återanvändbart munskydd inte långt borta. / In December 2019, the first cases of a virus called covid-19 were reported in Wuhan, China. The virus is spreading rapidly and in connection with the uncontrolled spread, the pressure on healthcare is also increasing. At the same time as healthcare is doing everything in its power to suffice, a global lack of protective equipment is reported. The manufacture of a surgical face mask, from fiber to finished product, consists of a comprehensive system and requires materials of specific fibers produced in advanced processes. Creating a face mask that possesses the possibility of reuse would have been an alternative with the aim of reducing the risk of face mask ending while minimizing disposable consumption. The purpose of this study is to analyze material selection, manufacture, construction and requirements for surgical face masks. The study also aims to explore alternative ways of creating a reusable face mask. The choice of method for collecting material has been based on literature studies of a primarily scientific nature. As the topic is highly current, news articles from trusted newspapers have been of value. Qualitative interviews were conducted with the aim of providing a clear insight into the healthcare work. A surgical face mask serves as a protective barrier against the transmission of infectious agents between staff and patients and is generally constructed in three different layers. The inner layer is made by a process called nonwoven meltblown, while the two outer layers, the upper and the lower, are made by a process called nonwoven spunbond. These three layers are then calendered together to form the filter media, which is then pleated and seamed in a converting line. The surgical face mask is a disposable item and is discarded immediately after use. Nawar Kadi, who is a professor at Textilhögskolan in Borås, is currently working on a project aimed at developing a partially washable face mask that thus functions to reuse. At present, there are many aspects to consider and questions to answer before the project can be realized in practice but with the right conditions, financial support and proven methods with underlying research, the possibility of creating a reusable face mask is not far away.

Examensarbetet har utförts vid ABB Power Transformers i Ludvika i plåtverkstaden, där stora transformatorlådor svetsas ihop. Tillsammans med vår handledare på företaget utformades ämnet för examensarbetet att bedöma luftkvalitet och arbetsmiljö vid punktsvetsning i koppar. Det fanns misstanke om att exponeringen för koppar var hög och en utvärdering av luftkvaliteten behövde därmed göras. Ingen tidigare exponeringsmätning vid svetsning i koppar har genomförts i plåtverkstaden.   Syftet med examensarbetet var att utvärdera och komma fram till tre åtgärdsförslag för att skapa en bättre arbetsmiljö vid punktsvetsning samt att begränsa exponeringen av svetsrök som bildas vid svetsning i koppar. Tre åtgärder var företagets önskemål. En exponeringsmätning av luftföroreningar vid svetsning i koppar gjordes för att kontrollera halten av ämnen i svetsröken, i förhållande till de hygieniska nivågränsvärdena. Exponeringsmätningen gjordes personburet. Dessutom gjordes stationär mätning samt mätning med direktvisande instrument. Användning av skyddsutrustning och ventilationen granskades. I samband med exponeringsmätning genomfördes intervjuer.   Resultatet av exponeringsmätningarna har visat att det hygieniska nivågränsvärdet för koppar överstegs kraftigt vid punktsvetsning med MIGsvetsmetoden. Nivågränsvärdet för koppar är 0,2 mg/m3 och det högsta uppmätta värdet uppgick till 1,05 mg/m3, mätt utanför svetsvisiret. Utifrån observationer om användning av skyddsutrustning har det noterats att det finns tillgång till lämplig skyddsutrustning men att den inte används i den utsträckning som den borde. De tre åtgärdsförslag vi utvecklade är att; (1) införa rutiner för filterbyte med jämna mellanrum, (2) börja använda integrerade utsug i större utsträckning samt att (3) förbättra lokalens ventilation genom att installera deplacerande ventilation. De två beräknade åtgärdskostnaderna, åtgärd (1) och (2), följer företagets PayOff-princip på 3 år.   Examensarbetet ska bidra till att alla medarbetare i plåtverkstaden blir medvetna om de risker som exponering av svetsrök innebär, men även att de tänker på sin egen och andras säkerhet och hälsa i deras dagliga arbete samt vidtar åtgärder som effektivt minskar exponeringen av svetsrök. Att satsa på en bra arbetsmiljö innebär kostnader för exempelvis inköp av skyddsutrustning och utbildning om risker. Detta bör dock inte ses som en kostnad utan att det snarare är en investering på sikt, som förbättrar medarbetares hälsa och prestationsförmåga i arbetet. Avslutningsvis: Att satsa på en bra fysisk och psykosocial arbetsmiljö är en investering för att få ett väl fungerande och lönsamt företag! / This thesis has been carried out at ABB Power Transformers in Ludvika at the plate shop, where large transformer boxes are welded together. The topic of the thesis was formulated together with our supervisor at the company, to assess air quality and work environment at the spot welding of copper. Copper exposure was suspected to be high, and an evaluation of air quality was needed. No previous exposure measurements when welding in copper have been made in the plate shop.   The purpose of this study was to evaluate and come up with three proposals for actions to create a better working environment for spot welding as well as to limit exposure to welding fumes generated during welding of copper. An exposure measurement of air pollutants during welding of copper was done to evaluate copper exposure compared to threshold limit values of substances in welding fume. Exposure measurements were made with personal monitors. In addition, measurement with stationary equipment and measurement with directreading instruments. The use of protective equipment and ventilation were studied. In connection with measurements interviews were made.   The results of exposure measurements showed that the occupational exposure limit value for copper was exceeded considerably during the spot welding with the MIG welding process. The threshold limit value of copper is 0,2 mg/m3 and the highest value measured was 1,05 mg/m3, measured outside the welding shield. Based on observations on the use of personal protective equipment it has been noted that protective equipment is available but not used to desired extent. Three control actions are proposed; (1) routines to change the respiratory protective equipment filter regularly, (2) start using local exhaust integrated in the welding gun to a greater extent and (3) improve the ventilation in the plate shop by installing displacement ventilation. The calculated costs for two of the actions, action (1) and (2), fulfill the company's payoff principle of 3 years.   The thesis will contribute to making all employees in the plate shop aware of the risks that the work involves exposure to welding fumes. But even that they think of their own and others' safety and health in their daily work and adopt measures that effectively reduce exposure to welding fumes. To invest in a good working environment involves costs, such as protective and risk education. However, this should not be viewed as a cost but rather that it is an investment in the long run, that improve employee health and performance at work. In conclusion: To invest in a good physical and psychosocial work environment is an investment to get an efficient and profitable business!

Workplace injuries are common in today's society due to a lack of adequately worn safety equipment. A system that only admits appropriately equipped personnel can be created to improve working conditions and worker safety. The goal is thus to develop a system that will improve construction workers' safety. Building such a system necessitates computer vision, which entails object recognition, facial recognition, and human recognition, among other things. The basic idea is first to detect the human and remove the background to speed up the process and avoid potential interferences. After that, the cropped image is subjected to facial and object recognition. The code is written in Python and includes libraries such as OpenCV, face_recognition, and CVZone. Some of the different algorithms chosen were YOLOv4 and Histogram of Oriented Gradients. The results were measured at three respectively five-meter distances. As a result of the system’s pipeline, algorithms, and software, a mean average precision of 99% and 89% was achieved at the respective distances. At three and five meters, the model achieved a precision rate of 100%. The recall rates were 96% - 100% at 3m and 54% - 100% at 5m. Finally, the fps was measured at 1.2 on a system without GPU. / Skador på arbetsplatsen är vanliga i dagens samhälle på grund av att skyddsutrustning inte används eller används felaktigt. Målet är därför att bygga ett robust system som ska förbättra säkerhet. Ett system som endast ger tillträde till personal med rätt skyddsutrustning kan skapas för att förbättra arbetsförhållandena och arbetarsäkerheten. Att bygga ett sådant system kräver datorseende, vilket bland annat innebär objektigenkänning, ansiktsigenkänning och mänsklig igenkänning. Grundidén är att först upptäcka människan och ta bort bakgrunden för att göra processen mer effektiv och undvika potentiella störningar. Därefter appliceras ansikts- och objektigenkänning på den beskurna bilden. Koden är skriven i Python och inkluderar bland annat bibliotek som: OpenCV, face_recognition och CVZone. Några av de algoritmer som valdes var YOLOv4 och Histogram of Oriented Gradients. Resultatet mättes på tre, respektive fem meters avstånd. Systemets pipeline, algoritmer och mjukvara gav en medelprecision för alla klasser på 99%, och 89% för respektive avstånd. För tre och fem meters avstånd uppnådde modellen en precision på 100%. Recall uppnådde värden mellan 96% - 100% vid 3 meters avstånd och 54% - 100% vid 5 meters avstånd. Avslutningsvis uppmättes antalet bilder per sekund till 1,2 på ett system utan GPU.
