Análise das condições ergonômicas de trabalho em atividades de demolição de piso e alvenaria

Abstract

The construction industry stands out in the national scenario due to the high number of absences related to occupational diseases and accidents at work, many of which result from muscle trauma caused by poorly directed workstations and activities. Currently, concern for the health of employees has become an important differentiator in the market, as it contributes to reducing companies’ costs and increasing proactivity. The objective of this monograph is to evaluate the ergonomic risks faced by workers involved in the demolition of masonry and floors in the construction industry. A qualitative research was carried out, descriptions as a case study in a construction site with a demolition stage in a hospital in southern Brazil, helping to survey the ergonomic risks collected on site and performing an analysis of each task using the OWAS method, which allowed identifying the risk associated with each activity. The data were found through photographic records, which allows generating a diagnosis on the posture required by workers during the execution of the tasks. The results obtained are periodic of necessary deadlines for corrective measures, highlighting the importance of applying ergonomic principles in the construction sector, due to the high number of tasks with significant ergonomic risks. It was possible to conclude that the back region and the position of the legs were the areas most affected in the observed tasks, and that the joint application of the ergonomic tool provided more accurate results due to its complementary nature.
