OCRA method for ergonomic risk assessment of work tasks

Tema ovog diplomskog rada je OCRA metoda za ergonomsku procjenu rizika ponavljajućih radnih zadataka. Zbog lakšeg razumijevanja područja prvo se opisuje ergonomija i njezin značaj u prevenciji mišićno-koštanih poremećaja koji se javljaju na radnim mjestima zbog nepravilnog pozicioniranja i držanja prilikom obavljanja radnih zadataka tj. zbog loše ergonomski oblikovanih prostora. U ovom radu se naglašava bitnost ergonomije u oblikovanju radnog prostora i utjecaja na zdravlje. Nakon upoznavanja s ergonomijom i mišićno-koštanim poremećajima slijedi detaljan opis OCRA metoda uz kratke primjere. Uz to slijedi i studija slučaja u proizvodnji agruma gdje se primijenila OCRA metoda za otkrivanje najrizičnijih radnih zadataka. Na kraju rada je prikazan konkretan primjer i ergonomska analiza pomoću OCRA metode te razlika između komisioniranja iz vertikalnog i horizontalnog karusela na određenom radnom mjestu uz izračun te zaključak.The topic of this thesis is the OCRA method for ergonomic risk assessment of repetitive work tasks. For easier understanding of the field, ergonomics and its importance in the prevention of musculoskeletal disorders that occur in the workplace due to improper positioning and posture when performing work tasks, ie due to poorly ergonomically designed spaces, are first described. This paper emphasizes the importance of ergonomics in the design of the work space and the impact on health. After getting acquainted with ergonomics and musculoskeletal disorders, a detailed description of the OCRA method follows with brief examples. This is followed by a case study in citrus production where the OCRA method was applied to detect the most risky work tasks. At the end of the paper, a concrete example and ergonomic analysis using the OCRA method and the difference between commissioning from the vertical and horizontal carousel at a particular workplace with the calculation and conclusion are presented
