In the construction industry there are several areas and various production processes where equipment that produces vibrations is used and where workers are potentially exposed to vibrations. Vibrations are a constant concern for the various dangers they pose to the worker and the occupational diseases associated with them. In the construction sector, about 10% of workers have vascular symptoms and 14% neurological. To assess the daily exposure of construction workers to vibrations and analyze the potential impacts on their health and their day-to-day work. Measurements were made to workers in construction site in Coimbra. The data collection process was performed using a triaxial vibration meter. We found that some of the tasks analyzed exceed the limit value of daily exposure stipulated by law. It was also found that the workers most exposed to vibrations are those who have less literary qualifications and that, in turn, are also those who have less knowledge about the health impacts associated with this same exposure. The study of occupational vibrations is extremely important for the construction sector. It is essential that there is more and more monitoring and implementation of preventive measures, aiming to provide workers with more safety and a better quality of life at work.
