Risk assessment, prevention and health support at a workplace of a selected plant in the Olomouc administrative region
SVOBODOVÁ, Klára
The objective of this work was to assess the health risk of local muscular stress of the upper limbs associated with the operator's job at a workplace of a selected plant in the Olomouc administrative region and to propose adequate provisions. Three research questions were asked: (i) "Are the permitted levels, set as percent fractions of the maximum load, complied with in the operator's job?" (ii) "Are the hygiene limits regarding the numbers of movements complied with in the operator's job?" (iii) "Which preventive actions are suitable to counteract the risk of local muscular stress during machinery assembling work?" This research was conceived as qualitative investigation. The group examined comprised employees at the position of operator at a workplace of a selected plant in the Olomouc administrative region. The research work comprised data collection by using the method of direct, non-participating and overt observation, and study of professional literature, applicable legislation and test protocols and reports. I processed the results of measurement and compared them with the hygienic limits laid down by Government Decree No. 361/2007 Coll. (as amended). Based on the assessment of the data obtained, I classed the operator's job as Category 3 with respect to the local muscular stress factor examined, based on the criteria set by Regulation No. 432/2003 Coll. (as amended). Based on the risk assessment and categorization of labour I proposed appropriate preventive measures to mitigate the effect of local muscular stress during the operators' work. I set up a simple questionnaire asking for a subjective assessment of the locomotive system stress during work as a tool for a more comprehensive assessment of the operators' local muscular stress. Based on the research I formulated the following hypothesis: "In view of the increasing trend of incidence of occupational diseases of the limbs due to overload, and taking into account the appreciable social and economic impacts of such diseases, more attention should be devoted to a systematic search, assessment and evaluation of the local muscular stress factor risk during work."
