Análise ergonômica no transporte manual de cargas: um estudo de caso em uma indústria de cimento

Abstract

This study aims to analyze the manual bags transport activity of 50kg in a cement production industry through ergonomic work analysis (aet), identifying environmental factors and working conditions of boots. For the aet possible, photographhic records were used, videos and interviews, addressing aspects of the survey, transportation and handling of cement bags, as well as observation of boots posture while performing the activity. Thus, they were taken into account both the qualitative aspects, as quantitative, as evidenced by the use of instruments for determining the concentration of agents in the environment, as well as some management tools, such as cause and effect diagram and interviews conducted during the field research. It was found that the high rate of absenteeism in the activity is related to rigid control of productivity, excessive lifting and manual transport weights and repetitive movements of the trunk flexion. From the results shown in aet, it was possible to propose preventive measures and some changes in the conditions of the working environment. To this end, he defended the existence of a proactive ergonomics program, task shifting and rest breaks, in order to minimize the effects of heavy workloads
