20.500.12556/RUL-174180 Zagotavljanje varnosti in zdravja pri delu v procesu galvanizacije Ensuring safety and health at work in the electroplating process Magistrsko delo obravnava varnostne, zdravstvene in okoljske izzive pri procesu galvanizacije. Delo preučuje možnosti zamenjave rakotvornega Cr (VI) z manj škodljivim trivalentnim kromom (Cr (III)), obvladovanje tveganj z uporabo metode HAZOP ter izboljšave za zmanjšanje okoljskega vpliva. Šestvalentni krom povzroča resne zdravstvene težave, med katere sodijo pljučni rak, poškodba dihal, prebavil, kože in oči. V okolju onesnažuje vodo, tla in zrak, kar negativno vpliva na rastline, živali in vodne ekosisteme. Na osnovi fizikalnih in kemijskih značilnosti je bila narejena raziskava, ali je zamenjava Cr(VI) s Cr(III) tehnično izvedljiva. Za oceno tveganj sta bili uporabljeni metodi AUVA in ZVD. Metoda AUVA je kvantitativna metoda, medtem ko je metoda ZVD bolj opisna, kvalitativna. Metoda HAZOP je pokazala, da so največja tveganja povezana s strupenimi hlapi in elektrolitskimi izlivi. Predlagani in uvedeni so bili tehnični in organizacijski ukrepi za zmanjšanje tveganja v procesu galvanizacije, skupaj z usposabljanjem osebja in evakuacijskimi protokoli. Okoljski vidik obravnava zaprte sisteme in pulzno elektrodepozicijo, ki zmanjšata porabo elektrolita za 20-30 % in emisije za 15-25 %. Delo je skladno z evropskimi predpisi, kot je Direktiva 2010/75/EU, ter poudarja potrebo po nadaljnjem razvoju Cr(III) tehnologij in raziskavah alternativnih kemikalij. Predstavlja celovit pristop k varnejšim in trajnostnim galvanizacijskim procesom, ki v čim večji meri skuša ohraniti zdravje delavcev, zagotoviti visoko varnost procesa in skrb za okolje. This master’s thesis addresses the safety, health, and environmental challenges associated with electroplating processes. The work examines the feasibility of replacing carcinogenic hexavalent chromium (Cr(VI)) with the less harmful trivalent chromium (Cr(III)), the application of the HAZOP method for risk management, and potential improvements to reduce environmental impact. Hexavalent chromium is known to cause severe health problems, including lung cancer, as well as damage to the respiratory and digestive systems, skin, and eyes. In the environment, it contaminates water, soil, and air, negatively affecting plants, animals, and aquatic ecosystems. Based on the physical and chemical characteristics of chromium, a study was conducted to assess whether the substitution of Cr(VI) with Cr(III) is technically feasible. Two risk assessment methods were applied: the AUVA method, which is quantitative, and the ZVD method, which is more descriptive and qualitative. The HAZOP analysis revealed that the greatest risks are associated with toxic vapors and electrolyte spills. Consequently, technical and organizational measures were proposed and implemented to mitigate these risks, including personnel training and the development of evacuation protocols. From an environmental perspective, the thesis discusses closed systems and pulse electrodeposition, which reduce electrolyte consumption by 20–30% and emissions by 15–25%. The study is aligned with European legislation, such as Directive 2010/75/EU, and emphasizes the need for further development of Cr(III)-based technologies and the investigation of alternative chemicals. Overall, the thesis presents a comprehensive approach to safer and more sustainable electroplating processes, aiming to protect worker health, ensure process safety, and minimize environmental impacts. galvanizacija krom (VI) krom (III) varnost in zdravje pri delu ocena tveganja galvanization hexavalent chromium trivalent chromium risk assessment safety true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-09-29 13:20:01 2025-09-29 13:20:16 2025-11-26 12:47:26 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 23057 258789123 Zupancic_Blaz_-_Zagotavljanje_varnosti_in_zdravja_pri_delu_v_procesu_galvanizacije.pdf Zupancic_Blaz_-_Zagotavljanje_varnosti_in_zdravja_pri_delu_v_procesu_galvanizacije.pdf 1 0B96720AD9736035ECF635CF553E8106 4f4511119b2a36b82137f3d65566693c1d04346177ac2acd45d7cdd1162047d5 13ed3e62-9d26-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=218944 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
