Působení prostředků individuální ochrany na příslušníky HZS hl. m. Prahy v různých zátěžových situacích / Effect of individual protestion to members of the Fire and Rescue Service of Prague in different stress situations.

NÁVRATOVÁ, Šárka January 2015 (has links)
Social and economical development of human society, in this case on the example of Czech republic, logicaly leads to improvement and invention of new individual protection instruments. Maximum protection in proportion to the lowest mobility limitation is the purpose. Diploma thesis explains, firstly, the basic concepts to make clear, what the issue concerns and getting better understanding for people.. It also deals with clothing comfort for firefighters. Clothing comfort can be divided into four groups and as the complex of essential for proper performance and convenience of trespassing firefighter. It is a condition where the optimal physiological functions of the body and neither clothing nor the environment does not create discomfort. Next section of diploma thesis describes the personal protective equipment to protect life and health trespassing firefighter and thereby increase its work in various special occurrences. Each unit of firefighters should be equipped with personal protection equipments, and instructed on how their use it, maintenance and periodic inspection. Another section of the theoretical part is devoted to the means of individual protection, which also protects the body of firefighter and his respiratory system. There are the types of breathing apparatus and a description of the knowledge that a firefighter must have to use the breathing apparatus to be optimized in accordance with the manufacturer's instructions and do not endanger the life of the user. Term minute ventilation is there also explained. Each person has a unique minute ventilation, which is very individual and depends on the work performed. Next point is the kinds of chemical protection suits, which are used during interventions, where the environment is contaminated with hazardous substances. The work of firefighters affects also negative effects. This issue is discussed in the next chapter, which describes the negative effects caused by the occurrence itself and the negative effects caused by climatic conditions at the location. The particular hierarchy of the fire brigade described in the next section, that deals with the General Directorate of Fire Rescue, the Fire Corps Rescue of country and fire protection units and their categories. The types of hazardous substances under the Chemicals Act and in accordance with the Order of chemical services are the last point of the theoretical part. The experiment is described and evaluated in practical part of diploma thesis which was attended by seven firefighters from the firefighter station Petřiny. Firefighters had to gradually undergo a prescribed route, they passed each time using a different suit. In order to avoid skewing the results, the firefighters between attempts to allow sufficient time for stale and soothe the body. They were obtained evaluation parameters in this way that were in the part of result processed and evaluated for total and average air consumption. The values, that were obtained, were subsequently processed into tables and graphs and the results were solved by using comparison and statistical methods. Conclusion of the work is devoted to the evaluation of the optimal protection of the firefighters, proposing measures for improvement and verification of the hypothesis that the performance of member of Prague rescue service is limited by individual protective means in extreme climatic conditions and load performance.

Assessment of the use of personal protective clothing among health workers in selected hospitals of Vhembe District in Limpopo Province, South Africa.

Mukhawa, Cecilia 20 September 2019 (has links)
Department of Advanced Nursing Science / MCur / This study was carried out to assess the use of protective clothing among health care workers in selected hospitals of Vhembe District in Limpopo Province, South Africa. Protective clothing is the corner stone of health care facilities and it remains the most cost effective measure which is currently available in public health intervention. Although personal protective clothing is one of the best lines of protection against hazardous exposures, many healthcare workers either shun this protective apparel or do not wear it in an appropriate manner at the appropriate time. The purpose of the study was to assess the use of protective clothing of health care workers in selected hospitals of the Vhembe District, in the Limpopo province of South Africa. The study followed a quantitative approach using a cross-sectional design. The population comprised of all health care workers in purposefully selected hospitals and the sample was 205 health care workers who were 21 years and older. A questionnaire was selfdesigned in English, translated into Tshi-Venda, Se-Sotho and Xi-Tsonga languages. Data was collected by the researcher in selected hospitals of Vhembe District. The statistical package for social sciences (SPSS version 25) was used to analyse the collected data. Validity and reliability were ensured. Permission to conduct research was obtained from the University of Venda Higher Degree Committee, Department of Health in Limpopo Province for Ethical Clearance, and the institutions where the study was conducted. The use of protective clothing among health care workers was found to be relatively low (8, 3%) probably due to unavailability of protective clothing in the hospitals, allergic reactions and ignorance. Lack of knowledge regarding the use of protective clothing could also explain the low yield of the detected cases for not using protective clothing while on duty in this study. Based on the findings, the study conclusions and recommendations were that all health care workers should follow the stipulated policy on protective clothing and periodic awareness campaigns to be held to conscientise workers on the importance of wearing personal protective clothing. / NRF

Problems encountered by Foskor mine workers with the use of personal protective equipment

Pilusa, Mogale Ludwick 30 November 2008 (has links)
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)

Die ontwikkeling van ’n veiligheidsmodel ten opsigte van die gebruik van persoonlike beskermende toerusting in die beroepsveiligheidsomgewing / THE DEVELOPMENT OF A SAFETY MODEL APPLICABLE TO THE USE OF PERSONAL PROTECTIVE EQUIPMENT IN THE OCCUPATIONAL SAFETY ENVIRONMENT (translated from Afrikaans)

Schoeman, Johann Petrus January 2013 (has links)
Proefskrif ten opsigte van die voldoening aan die vereistes vir die graad: Doctor Technologiae: Omgewingsgesondheid in die Fakulteit Toegepaste Wetenskappe aan die Cape Peninsula University of Technology 2013 / The economical impact of occupation-related diseases and injuries places an immense financial burden on the inhabitants of a country and its industry. There is little doubt that the human factor is the single most important contributing factor to critical work-related accidents. Safety measures in the field of occupational health and safety are normally implemented according to a specific hierarchy, whereby the use of personal protective equipment is seen as the last outcome to protect workers against accidents and disease. However, there is little doubt that the correct use of personal protective equipment can protect a worker against injury and even death. The purpose of this research was to address a limitation through the development of a risk model that is specifically aimed at the application of personal protective equipment in the field of occupational health and safety. This model informed the factors influencing the use of personal protective equipment, and is instrumental in the prevention of unsafe behaviour at work. This documented method of research analysed various risk models from previous research studies in order to develop a new model, the Factor Integration Model (FIM). This model consists of five components each with its own specific elements that are interrelated. Each element has a specific value that was determined by 20 local and international experts in the field of occupational health and safety. The 54 elements of the model were used to create an electronic Excel®-based questionnaire, namely the Electronic Risk Categorising Package (ERK). The ERK can be utilised to categorise the worker`s use of personal protective equipment into a low, low medium, high medium and high risk scale. The utilisation and efficiency of ERK were tested at six different industries by comparing the categorisation of ERK with that of the supervisors. In order to prevent research bias, neither the researcher nor the supervisors were familiar with each other’s categorisations. The results were compared and the ERK showed a correct categorisation of the use of personal protective equipment in 75% of the cases. It was further found that in the cases where the prediction was not 100% correct, the ERK noted the borderline cases and the human factor of wrong prediction by the supervisor had to be considered. The research concluded that the use of personal protective equipment is influenced by various factors and should not be seen in isolation. The role of both management of a company and human behavioural change should never be underestimated. The ERK is a useful aid to predict risk behaviour as well as the use of personal protective equipment in the occupational health and safety field.

Pelikán, Jakub January 2016 (has links)
This thesis deals with common problem health protection at work. Namely hand protection during the work in very cold environment. It’s an analysis of materials suitable for apparatus used for measuring the thermal resistance of the gloves. There was analysed a range of materials. Every single sample was tested for heat conductivity and afterwards was assessed the suitability of materials. Heat was generated by electricity. Ocured heat fields was assessed with thermocamera. After performed experiments of carbon fiber we haven’t reached any satisfying results which we could use for manufacturing of this device. On the other hand kapton film has given very interesting results which we would recommend eventually. Kapton film needs to be modify according to the method listed in the conlusion. This thesis gives us a clear overview and inspiration for additional research of this device. It finds it’s place in research facilities and companies manufacturing protective clothing.
