    Assessment of occupational health and safety issues in geothermal energy systems
    (ECOS 2020 Local Organizing Committee, 2020) Erten, B.; Oral, B.; Utlu, Z.
    Geothermal energy is a sustainable, low cost, inexhaustible, environmentally friendly energy source. On the other hand, the fact that it can be used in many ways, such as electricity generation, heating, and cooling in the health sector, makes geothermal energy important in the world. For this reason, occupational health and safety (OHS) is of great importance in the success of geothermal energy projects, system efficiency, assessment of environmental impacts, protection of human health and prevention of economic losses. In this study, a holistic approach to geothermal energy plants with OHS issues has investigated. Accordingly, a literature survey has conducted on the dangers encountered or may be encountered in geothermal power plants, occupational health, and safety issues. Also, national and international legal regulations were researched. In this regard, Turkey, as well as legal regulations applied in areas where Iceland and the Philippines in geothermal energy production in the world, have shared first place. To analyze the functioning of field application is made observations in a geothermal power plant in Turkey. In this regard, it has been determined that national and international labors in geothermal energy should be supported with a common language, scientific infrastructure, applicability, and legal regulations that will form a basis in terms of OHS. By defining the environmental effects, dangers, and risks of geothermal systems, the emphasis has been placed on the work to be done in the field of OHS. In conclusion, when the legal regulations and literature on geothermal power plants are examined, it is seen that there is a need for guidance studies on the location and importance of OHS issues. © ECOS 2020.All right reserved.

    Evaluation of electrical field effects of façade type a PV panel with occupational health and safety perspective, a case study
    (ECOS 2020 Local Organizing Committee, 2020) Erten, B.; Karabuga, A.; Utlu, Z.
    In this study, the trend towards sustainable building concept has increased considerably in recent years. For this reason, the environmental impacts of photovoltaic (PV) systems integrated into the building have been examined in terms of occupational health and safety (OHS) for buildings that produce their own energy. In addition, the efficiency of the integrated PV systems outside the building is discussed. Therefore, the study is based on two main factors such as environmental effects and system efficiency. We measured the electrical field (electric, magnetic and electromagnetic) of the façade type PV system that building-integrated in Turkey for investigating the environmental effect. The measurements are carried out using the relevant standards, legal regulations and measurement methods at a total of 16 points in the front, top, back and in the inverter room of the panel one day per month for one year. The measurements include the electrical field values of the PV system area, the indoor areas covered by the PV area and the inverter room where the electrical systems are located. The measurements made in the inverter room are evaluated separately, since people are not intense and are located in a separate room. There are specific situations in terms of danger and risks due to the different functioning in this area. Measurement results are interpreted in accordance with OHS rules and legal regulations in terms of human, environment and workplace. While this study highlights the effects of electrical field effects occurring in façade type PV systems in terms of the OHS, it contributes to the proactive approach, which is the main purpose of the OHS. In result of this study, we have obtained during the measurement period, electric field values vary between 0.053 and 0.096 V/m. In addition, we have measure electromagnetic flux values are between 0.154 and 0.242 Gauss. © ECOS 2020.All right reserved.
