    The study on particulate matter evaluation in the production area of CAUCHOSIERRA S.A. included an analysis of all activities involved in the tire retreading process. All operators are exposed to chemical risks, including respiratory agents that severely impact health. The methodology adopted for the evaluation of particulate matter in the production area follows the guidelines of the Technical Guide for the Evaluation and Prevention of Risks Related to Chemical Agents in the Workplace. It is based on the method recommended by UNE-EN 689 and the qualitative assessment by INSHT. This approach encompasses the stages of identification, measurement, evaluation, and the proposal of control measures. Significant concentrations of PM 1.0, PM 2.5, and PM 10 particles were identified during the process, frequently exceeding the daily exposure limit values (VLA-ED), especially for respirable particles and compounds such as carbon black. These results were compared with the exposure limits established by the ACGIH and the MAK list, highlighting a potentially hazardous exposure for workers. To validate the tests, Pearson's coefficient was applied, as recommended by ISO 17025:2017. The Guide to the Expression of Uncertainty in Measurement (GUM) was used to calculate the uncertainties associated with the measurements, ensuring a precise and reliable assessment of the data obtained. Finally, control measures were proposed through the development of various protocols, including specific activities to mitigate particulate matter exposure in the production area.
