Quantitative analysis of occupational accidents in building maintenance

Abstract

This study aims to quantitatively analyze occupational accidents due to falls during maintenance in buildings, focusing on building cleaning activities carried out in Brazil over a 15-month period. The research used data extracted from Occupational Accident Reports (CATs), organizing them according to geographic, occupational, temporal and injury nature criteria. The methodology was structured in four stages: survey, tabulation, statistical analysis and calculation of conditional probabilities. The results indicated a higher incidence of accidents among workers in the maintenance services group, predominantly between 30 and 39 years old, with fractures standing out as the most common type of injury. The information obtained reveals weaknesses in the preventive systems adopted and reinforces the importance of the adequate use of PPE, ongoing training and monitoring of safety standards. As a future development, it is recommended to expand the database and include qualitative approaches to complement the findings and guide improvements in occupational safety practices in the construction industry.
