Since 2022, Nexa has maintained and continuously improved a robust risk management system for its operational activities, structured according to the G-MIRM (Global Mining Industry Risk Management) methodology developed by the University of Queensland in Australia, with the aim of fostering a strong culture of risk-based decision-making. More than 4,000 employees and 6,000 permanent contractors have already been trained to identify, assess, and manage risks associated with processes, changes, and new projects, as well as routine and non-routine activities and service fronts, applying these concepts in practice through:

• Definition and management of critical controls in Mining and Smelter operations: catastrophic loss scenarios were mapped, and the respective critical controls were established; these are periodically inspected and audited based on reference standards and action plans aimed at continuous improvement.
• Critical risk protocols: protocols with specific requirements to prevent fatalities associated with the main risks present in metallurgical and mining operations are defined, communicated, and reviewed regularly.
• Dynamic risk assessment: Changes in processes, technologies, personnel, or operational conditions undergo a structured change management process, including hazard identification, risk assessment, and definition of necessary controls prior to implementation.
• Task risk assessment: activities are analyzed using management system tools, such as Work Permits and Task Risk Analysis, conducted jointly by leadership and the operators directly involved.
• Creation of reference standards: technical and operational standards are developed and maintained for activities classified as high-risk, guiding procedures, qualification requirements, equipment, and minimum controls.
• Reporting of risk conditions: workers have access to the “Fale Fácil” communication tool to record, in a simple and accessible manner, hazardous situations, near-misses, and opportunities for improvement identified during routine operations.
• Systematic monitoring by leadership: there is a structured schedule for verifying and supporting risk management at all levels of the organization, ensuring the effective use of tools, the quality of analyses, and the implementation of continuous improvement actions.
