Identificação e análise de riscos à saúde e segurança do trabalhador da construção civil utilizando sensoriamento vestível (wearable)

Abstract

This research demonstrated that the use of wearable sensing technologies can enhance the way health and safety risks are identified in construction. From the analysis of two distinct construction sites — a retrofit project in Porto Alegre and a conventional building site in Portão — 58 occupational risks were mapped, six of which were classified as critical, mainly in physically demanding activities such as the removal of ceramic coatings and plaster. The workers’ profile revealed young professionals, with low levels of schooling and limited experience, exposed to conditions that go beyond physical effort: 25% showed symptoms of Common Mental Disorder (CMD), associated with psychosocial factors such as productivity pressure, task insecurity, and intense heat. Environmental and physiological monitoring highlighted the direct influence of climate (external temperature) and tasks on vital parameters, with increases in heart rate and blood pressure during critical activities. These findings reinforce the importance of scheduled breaks and task redistribution as effective protective measures. The study also advanced by proposing a predictive model capable of explaining 75% of risk variation, showing that wearable sensors can support real-time decisionmaking and anticipate situations of physical and mental illness. In summary, the results reveal that the integration of technology, environmental indicators, and attention to psychosocial aspects not only broadens the understanding of risks but also points to concrete pathways for creating safer, healthier, and more humane construction sites.
