Summary: | This study aims to analyze the manual transport activity of 50kg bags in a cement production company by
means of ergonomic work analysis (EWA), identifying environmental factors and loaders’ working conditions.
In order for EWA to take place, photographic records, videos and interviews were performed. It covered aspects
related to lifting, transportation and handling of cement bags, as well as observations of loaders’ posture while
performing the activity. In this sense, both qualitative and quantitative aspects were taken into account, which
were evidenced by the use of instruments for determining the concentration of agents in the environment. In
addition, some management tools, such as the cause and effect diagram, and interviews conducted during the
field research were used. It was found that the high rate of absenteeism in the activity is related to the strict
control of productivity, the excessive lifting and manual transport of weights, and repetitive trunk flexion movements.
The results shown by the EWA made it possible to propose preventive measures and some changes in
the work environment.
