Abstract: Human activities generate solid or liquid particulate waste suspended in the air, known as particulate matter. Due to the nature of working with wood, carpentry workshops are places where wood dust is generated, which, without proper treatment, causes serious health problems for workers and the community at large. In this study, particulate matter PM2.5 and PM10 generated at the Furniture and Woods Freire Lugo company in the city of Puyo were quantified, along with its influence as a risk factor on workers' health through exposure indices. The methodology involved observing the furniture manufacturing process to define exposure times to wood dust and processing areas. Particulate matter readings were taken using the AEROCET 532 instrument in different work areas. Information about substandard actions and conditions was collected through observation sheets. Among the results, three zones or areas were defined: Planing, Marking, Sanding, and Painting. Substandard actions indicate negligence in the use of personal protective equipment, especially during sanding and painting activities. Additionally, there is inadequate material storage. Regarding substandard conditions, improvements are needed in machinery maintenance processes, electrical installations, and enhancing ventilation and lighting in workspaces. Exposure index results indicate that exposure to wood dust poses an acceptable risk for workers in all areas. However, ventilation systems and the mandatory use of personal protective equipment in the sanding and painting area need improvement. It concludes with some recommendations for improving the company's infrastructure to enhance the working environment.
