Impactos do Lean Safety com a Certificação da norma ISO 45001:2018 em indústrias manufatureiras.

Abstract

Brazil loses productivity and resources year after year due to work accidents, also compromising the integrity and lives of thousands of people. According to the guidelines of the ISO 45001:2018 standard, an occupational health and safety management system structured according to the standard can help organizations minimize or eliminate risks and hazards, contributing to accident prevention. Lean tools, fundamentally designed for operational excellence through increased efficiency and waste reduction, can be applied in this context. Therefore, the objective of this study is to associate, highlighting for each requirement of the standard, which Lean Safety tools can aid their implementation in the manufacturing industry, based on the results of the Analytic Hierarchy Process (AHP) matrix. The methods employed included bibliometric research using R software with selected keywords: "Lean" OR "Lean Thinking" AND "safety" OR "ISO 45001" AND "industry" OR "manufacturing". Subsequently, the AHP matrix was applied as a decision-making approach to associate tools and requirements. The results indicated that the most associated requirements were Operation, Improvement, and Planning, with the corresponding tools showing the highest weights being 5S, Single Minute Exchange of Die (SMED), Value Stream Mapping (VSM), and Poka Yoke. The AHP mapping demonstrates synergy between Lean Safety and ISO 45001, facilitating certification through contextual analysis, modification of working conditions, and safety mindset development. Despite the limitation of single-expert judgment, it provides a practical basis for systemic or targeted implementation, enhancing occupational health and safety (OHS) in manufacturing. Empirical validation using the Delphi method, joint cost analysis, and trends such as sustainability and new technologies are suggested.
