What are the main requirements and conditions established by the Brazilian NR-10 regarding safety in electrical installations and services?


a) The NR-10 establishes the minimum requirements and conditions to implement control measures and preventive systems to ensure the safety and health of workers who interact directly or indirectly with electrical installations and perform services with electricity. The norm requires the elaboration of the Electrical Installations Record (PIE), which must contain, at least, safety and health technical and administrative procedures and instructions, documentation of inspections and measurements of the Atmospheric Discharge Protection System (SPDA) and electrical grounding, specification of collective and individual protection equipment and tools, documentary evidence of the qualification, authorization, and training of workers, results of electrical insulation tests performed on individual and collective protection equipment, certifications of electrical equipment and materials in classified areas, and technical inspection reports updated with recommendations and adaptation schedules.

In its last revision, the concept of electricity work management was strongly introduced due to the need for several specific controls to be implemented for the execution of activities with electricity. The norm even mentions previous analysis at the project level and determines collective protection levels for risk control.

The norm also establishes the minimum requirements for the operation of elevators, cranes, industrial conveyors, and conveyor machines, among others.
