The Tailings and Dams Management System (TDMS) establishes the guidelines for managing the safety of Vale's dams and tailings storage structures. The TDMS is aligned with the Global Industry Standard for Tailings Management (GISTM) and adopts the most advanced international guidelines as a reference. Through the pillars of People, Routine, Performance and Risk Management, the TDMS defines roles and responsibilities and establishes standards and requirements that translate Vale's Values, Ambitions and Principle for managing the safety of Dams and EARs.

Hazard Identification and Risk Analysis: 

The Hazard Identification and Risk Analysis (HIRA) process is defined through a risk identification and improvement methodology aimed at events classified as Material Unwanted Events (MUEs), which are high-consequence incidents that require the highest level of attention. HIRA assists in identifying priority risks in the company and implementing critical controls that can prevent an MUE from occurring in the first place or minimize the consequences if an MUE occurs and also in the definition of actions with determined and feasible deadlines, for identified vulnerabilities, opportunities for improvement, studies to improve the understanding of a risk, treatments and reduction of risk priority, among others. The identified risks are recorded and managed in Vale's risk management system (Bwise).
