3.10 Occupational Safety Regulatory Norms (NRs): NR 10 - Safety in Electricity Installations and Services

The Regulatory Norm 10, known as NR 10, is one of the most important norms when we talk about work safety. It was created with the aim of ensuring the safety and health of workers who, directly or indirectly, interact with electricity facilities and services. This standard is extremely important, as working with electricity can pose significant risks, including electric shocks, burns and even death.

NR 10 covers all phases of electrical energy, from generation to consumption, including transmission, distribution and use. It establishes preventive measures in work safety, seeking to guarantee the safety of all those involved. These measures include the implementation of safety systems and procedures, the use of personal protective equipment (PPE) and specific training.

Main Aspects of NR 10

NR 10 is divided into several sections, each addressing a specific aspect of safety in electrical installations and services. Some of the most important sections include:

Control Measures

This section of NR 10 establishes the control measures that must be implemented to guarantee the safety of workers. This includes de-energizing electrical circuits before any work is carried out, properly signposting workplaces and installing safety devices to prevent accidents.

Collective Protection Measures

NR 10 also establishes collective protection measures that must be implemented. This includes installing barriers and isolation to prevent accidental contact with live parts, using insulating tools and equipment, and implementing safety procedures for working at height and in confined spaces.

Personal Protective Equipment (PPE)

PPE is an essential part of safety in electrical installations and services. NR 10 establishes the requirements for the selection, use and maintenance of this equipment, which include insulating gloves, helmets, safety glasses, rubber boots, among others.

Training

NR 10 establishes that all workers who interact with electricity installations and services must receive specific training. This training must address the risks associated with the work, control and protection measures and emergency procedures.

Conclusion

NR 10 is a fundamental standard to guarantee the safety and health of workers who interact with electricity installations and services. It establishes control measures, collective protection, use of PPE and training, which must be strictly followed to prevent accidents and protect workers' lives. Therefore, it is essential that everyone involved in this type of work has a thorough understanding of this standard and follows its guidelines rigorously.
