With the expansion of global grain production, in which Brazil ranks 4th with 7.8%, and, in light of the estimated production for the 2022/2023 harvest of 309.9 million tons, there is a deficit in storage capacity, currently representing 60.9% of production. Given the importance and expectation of expanding, it is necessary to prevent illnesses and accidents linked to this process. This work aims to develop an occupational hazards management model during the grain storage and drying processes, to determine the hazards that workers are exposed in their activities. The methodology was applied in western Paraná, Brazil, in a grain drying and storage unit during the inter-harvest and harvest periods to analyze, identify, evaluate, prioritize, and develop an action plan for the hazards. Among the hazards identified in the literature and at the site, exposure to heat and noise was evaluated, generating a score that represents the hazard situation in the environment. Of the 104 possible points in the evaluation, occupational exposure to heat obtained the lowest score of 70 (regular level), compared to noise with a score of 90 (normal level). For solving identified non-conformities, it can be highlight the replacement of thermal protection gloves and installation of a on-site temperature and humidity meter. With the methodology, it is possible to evaluate hazards and propose mechanisms that lead to their resolution, prioritizing the most critical levels according to the generated score.
