The role of occupational safety in road works: Implementation of preliminary risk analysis in the execution of asphalt resurfacing

Abstract

The aim of this research is to present, through the application of a risk analysis technique, a mapping of dangerous occurrences, the causes and consequences of the risks to which highway construction workers are exposed, as well as to recommend appropriate control measures for the case study investigated. A photographic survey was carried out on a critical stretch of road resurfacing work located on Avenida Dona Otília, in the São Pedro district of Manaus/AM. The Preliminary Risk Analysis (APR) technique was used to draw up a qualitative and quantitative opinion of each function included in the construction work process, with the aim of diagnosing the risks and finding improvements in the working conditions at each position, with a view to the well-being and protection of workers' lives. However, the survey indicated a higher incidence of physical risks, especially in the role of paver operator. It is therefore necessary to introduce an accident prevention policy, training workers to recognize potentially dangerous situations before accidents or near misses occur, and to keep records of both. Another important measure is to check the condition of EPI and implement equipment control sheets. The risk of being run over was observed in all functions, and it is important that there is adequate signage for employees on the road, the works and the maximum speed allowed on these stretches.

“…Desse modo, as fachadas dos edifícios desempenham um papel relevante em termos de sustentabilidade ambiental, pois têm um impacto direto em sua performance lumínica e térmica. Na maioria dos casos, encontrar um método para equilibrar esses índices de desempenho favorece a tomada de decisões na busca pela melhoria do conforto dos edifícios para seus ocupantes (Souza Nascimento, 2019;Queiroz et al, 2021;Zwirtes et al, 2022a;Nascimento et al, 2023).…”
