The certification of maintenance electricians is a crucial process that ensures these professionals possess the necessary skills and knowledge to safely and effectively perform their duties. The NBR 15152 standard provides a comprehensive framework for the qualification and certification of maintenance electricians. This standard outlines the requirements, processes, and competencies needed to achieve and maintain certification.
Understanding NBR 15152
NBR 15152, established in January 2015, details the systematic approach required for the qualification and certification of maintenance electricians. It defines the roles, responsibilities, and activities of these professionals, who work in various environments such as fields, workshops, and laboratories. The standard is crucial for maintaining high safety and operational standards across electrical maintenance services.
Qualification Requirements
To qualify as a maintenance electrician under NBR 15152, candidates must meet several criteria. The minimum educational requirement is the completion of the 5th year of elementary school. Additionally, candidates must demonstrate satisfactory performance in a recognized training course of at least 160 hours. Those with a technical course in electrotechnics are exempt from this requirement.
Moreover, candidates must complete a 40-hour course in NR-10, which focuses on safety regulations for electrical installations and services. For those undergoing recertification, a minimum of 20 hours is required.
The Certification Process
The certification process involves both theoretical and practical examinations. Candidates must register with an accredited Personnel Certification Body (PCB) and provide documentation verifying their educational background, technical training, and work experience. Physical and mental fitness, as defined by the standard, must also be demonstrated.
Candidates must pass a written or theoretical exam with a minimum score of 50% on each element of Unit 1 and an overall average of 70%. The practical exam, which evaluates the competencies detailed in Unit 2, requires a minimum score of 70% on each task and an overall average of 70%.
Post-Examination Procedures
After passing the exams, candidates undergo a technical-pedagogical interview to discuss their performance and receive feedback. This interview helps in identifying strengths and areas for improvement, providing a foundation for ongoing professional development. A detailed report of the candidate’s performance is issued, serving as a guide for their future career path.
Appeals and Recertification
Certified professionals have the right to appeal decisions regarding exam results, suspension, or cancellation of certification. Appeals must be formally submitted to the PCB, which is required to respond within 30 days. If the appeal is not satisfactorily resolved, it can be escalated to Inmetro and ultimately to the Brazilian Committee for Conformity Assessment (CBAC).
Maintaining certification requires ongoing adherence to the standards set by NBR 15152. This includes continuous professional development and regular recertification to ensure that maintenance electricians remain updated with the latest practices and technologies in their field.
Conclusion
The certification of maintenance electricians as per NBR 15152 is vital for ensuring the safety and efficiency of electrical maintenance services. By adhering to rigorous standards and a structured certification process, electricians can provide high-quality services while minimizing risks associated with electrical work. This not only protects the electricians themselves but also ensures the safety and reliability of electrical systems in various settings.
