Ergonomic Evaluation as a Holistic Evaluation in Company Assembly Hydrometers

Abstract

The manual assembly equipment has been cited as one exposed to several ergonomic constraints, such fractionation is associated with the task of occupation, facilitating the monotony and high number of repetitive movements that may cause occupational diseases of physical and psychological harm. Seeking to adapt the work to the characteristics and skills of professionals in the assembly of the sector totals, ergonomic intervention System Human-Machine Task was performed in an industry located in Recife-PE assembly of water meters, comprising the steps of Ergonomic Assessment, Ergonomic Diagnose and Ergonomic Projects. To meet the objectives of the first stage, unsystematic observations, documentary analysis of records and PPRA PCMSO Company, open interviews and structured questionnaires with workers in the sector were applied. In the second stage, the deepening of the problems found in the first study were from task analysis, systematic observations for analysis of postures assumed, according Worksheet RULA (Rapid Upper Limb Assessment) analysis of the physical costs from the implementation of the diagram discomfort/pain, and anthropometric studies by two-dimensional anthropometric dummies. In the third step, were proposed suggestions for improvements to the problems encountered and prioritized. The results indicated order problems and physical environmental, organizational, job, biomechanical and psychosocial. The high levels of discomfort/pain are justified by inadequate occupational postures combined with repeatability of movements in accomplishing the task. Therefore, are necessary changes and adjustments in working conditions of workers in the sector under study, to provide them better quality of life.
