SUBJECTIVITY IN DAM RISK MANAGEMENT: THE IMPACT OF THE TRAINING OF CIVIL DEFENSE AGENTS

Abstract

The collapses of mining tailings dams in Mariana (2015) and Brumadinho (2019) highlighted structural weaknesses in risk management and safety governance in Brazil. These disasters exposed flaws in regulatory oversight, corporate hierarchy, and the role of Civil Defense agents in disaster prevention and response. This study investigates how the lack of technical training of Civil Defense agents influences the greater or lesser presence of subjectivity in decision-making in dam safety management. The research adopts a qualitative approach through documentary analysis, considering official reports, regulatory frameworks and academic studies. To rank the factors that impact the subjectivity of these agents, the GUT Matrix (Severity, Urgency and Tendency) was used. The results indicate that inadequate training, hierarchical corporate structures and the lack of clear protocols significantly compromise risk governance. In addition, the absence of structured training limits the ability of agents to interpret technical reports, question business practices, and implement effective preventive measures. Although technical training is not the only determining factor for efficient management, the study highlights its importance in reducing vulnerabilities and increasing objectivity in decisions. The findings highlight the need for ongoing training, independent audits, and improvement of regulatory standards. The study also recommends greater involvement of local communities in safety protocols to ensure transparency and accountability. These measures are essential to prevent future disasters and strengthen dam safety governance in Brazil.
