Resumen

Introduction: This study assessed the impact of implementing an Occupational Health and Safety Management System (OHSMS) based on ISO 45001:2018 at a primary forest processing facility in Puno, Peru—an industrial site characterized by high occupational risks. Methods: A quasi-experimental design with pre-test and post-test measurements was applied to a census of 37 employees (n=37). Data collection involved a 22-item structured survey mapped to the ISO 45001 clauses, the IPERC matrix for risk assessment, and direct observations. Results: Post-intervention results showed significant improvements (p < 0.001) across all clauses, with safety perception increasing by 45%, leadership participation by 41%, and proper use of personal protective equipment by 52%. The most significant progress was observed in Planning (Z = 4.47), Support (Z = 4.99), and Performance Evaluation (Z = 4.55). Conclusion: Implementing ISO 45001:2018 produced measurable advancements in preventive culture and risk mitigation. These findings provide empirical support for adopting the standard in Small and Medium-sized Enterprises (SMEs) within developing economies.
