Avaliação da segurança no trabalho durante a operação de medidores de vazão e coleta de amostras de água em recursos hídricos

Abstract

This study investigates the compliance of hydrometricians’ activities with Regulatory Standards NR 06, NR 17 and NR 31, focusing on safety, health and ergonomics at work in aquatic environments. Given the importance of water resource monitoring for sustainable water management, it is essential to ensure safe conditions for workers involved in these activities. The objective was to characterize the occupational risks faced by hydrometricians and to evaluate the appropriate use of Personal Protective Equipment (PPE) and ergonomic practices. The methodology included the application of checklists in the field and direct observations of working conditions, complemented by a comparative analysis with the existing literature. The results indicated that, despite general compliance with the standards, there are gaps, such as the absence of signage in risk areas and the need for a more complete ergonomic assessment. The analysis suggests that, although safety practices are being followed, improvements are needed, especially in the supervision and provision of specific PPE, such as respiratory masks and protective glasses. It is concluded that, although the safety of hydrometricians complies with regulatory standards, there is room for improvements to ensure a safer and more efficient work environment. The adoption of proactive safety practices and the continuous review of protection policies are essential for the comprehensive protection of these professionals.
