Ergonomic Analysis

Abstract The profession of a seller (especially in small grocery stores) does not enjoy a social respect. The reasons for this are, above all, low requirements, low salary and difficult working conditions. In addition, too little attention is paid in the literature to this profession from the point of view of safety and hazards at work. However, the problem of working conditions in the position of a salesman is an important issue concerning a very large number of people. The paper deals with this difficult topic by describing selected methods of ergonomic analysis and using them to assess occupational risk at the seller’s workplace. In the paper, the results of the Ergonomic Checkpoint List, as well as the results of questionnaire surveys are presented. All the results are related to the possibility of proper identification and the probability of hazards occurrence in the position of a seller.

Musculoskeletal disorders cause serious problems that affect workers in many sectors. The objective of this study is the ergonomic analysis of melon cultivation farmers in Almeria-type greenhouses. For this, the rapid upper limb assessment (RULA) method has been applied after carrying out a detailed process of observing the farmers’ tasks. The study shows that 65% of the postures have a very-high-risk level, 26% high, 9% average, and no posture is found with a low risk. They also show that in 69.57% of the postures, the upper limbs are less affected than the others such as the neck, trunk, and lower limbs. Measures are proposed to improve the working conditions for workers.

Ergonomic Analysis

Abstract For the analysis of musculoskeletal workload and associated potential hazardous working conditions as well as musculoskeletal symptoms in worker populations among various occupations different approaches are taken, and extensive data collection studies are being accomplished. Questions are targeted on musculoskeletal workload and associated potentially hazardous working conditions can be categorized into seven indices (force, dynamic and static load, repetitive load, climatic factors, vibration and ergonomic environmental factors). Evaluation focus on standing, sitting, walking and uncomfortable postures, the indices constitute a brief overview of the main findings on musculoskeletal workload and associated potentially hazardous working conditions. The validity of the findings is fair when compared with an index of psychosocial working conditions and discomfort during exposure to physical loads. Worker groups with contrasting musculoskeletal loads can be differentiated on the basis of the indices and other factors. It appears that most indices and factors show significant associations with low back and/or neck-shoulder symptoms. This simulation model NIOSH analysis can be used as a simple and quick approach to identify worker groups in which a more thorough ergonomic analysis indicates possible improvements in load factor using particular exoskeletons at work.

Methodological Strategy

This study aims to analyze the impacts of the lack of ergonomic view in the projects of equipment design on workers’ health from the maintenance sector, in the mining industry context. To understand the operators’ health, maintenance activities of three types of equipment were analyzed: pump, crusher and sieve. The methodological strategy of Ergonomic Analysis of the Workplace (EWA) was used. Thus, changes in these activities are required, since some postures adopted for their performance were considered severe and with high risk. Bearing weight above the shoulders and uncomfortable positions are conditions resulted from failures in the equipment designs. To alleviate the problem, it is suggested the adoption of innovative tools or the creation of new supportive devices to improve working conditions of these maintenance professionals.
