NR-10, everything you need to know!

What is the difference between NR and NBR?

What differentiates a Regulatory Standard (NR) from a Brazilian Standard (NBR) is mandatory. Regulatory Norms are mandatory standards developed by the Ministry of Labor and Employment (MTE) and are aimed at occupational health and safety, and may generate labor liabilities, penalties, fines, embargo and interdiction in case of non-compliance with such standards.

The Brazilian Standards are part of a group of guidelines prepared by the Brazilian Association of Technical Standards (ABNT) , for standardization. Therefore, the adoption of the established criteria is not legally required.

In which areas does NR-10 apply?

NR-10 applies to all public, private companies or any other establishment that hires employees to work with activities related to electricity, such as:

  • Stages of electricity generation
  • Electricity transmission
  • Electricity distribution
  • Electric power consumption
  • Construction of the electrical project
  • Assembly of electrical project
  • Maintenance of electrical installations
  • Any activity carried out in your vicinity

It is also important to note that in the absence or omission of the official technical standards established by the competent bodies, the applicable international standards must be applied.

Main topics of NR-10

NR-10 makes us aware of the risks that exist when working with electricity and for this reason it is divided into several topics that cover different topics such as:

  • Control measures
  • Collective protection measures
  • Individual protection measures
  • Project security
  • Safety in construction, assembly, operation and maintenance
  • Safety in de-energized electrical installations
  • Safety in energized electrical installations
  • High voltage (AT) work
  • Qualification, qualification, training and authorization of workers
  • Fire and explosion protection
  • Safety signs
  • Work procedures
  • Emergency situation
  • Responsibilities
  • Final dispositions

Is the NR-10 course mandatory?

Yes, it is mandatory! For workers authorized to work in electrical installations, they must have specific training on the risks arising from the use of electrical energy and the main measures for preventing accidents in electrical installations. Annex III of the NR-10 standard informs the minimum requirements for the basic NR-10 course.

What is the importance of having an NR-10 course?

We cannot deny that work with electricity needs a lot of care and that is why the NR-10 course or training serves to raise awareness of the risks present in work with electricity.

Currently, many companies grant NR-10 training when they hire a professional in the field, but it is essential to have an NR-10 certificate, since NR-10 training for companies is generally only valid for the company, this ends up limiting the worker.

It is important to look for an NR-10 course to be aware of the risks present in the area, to have a  differential in the job market  for example. The NR-10 course is indispensable for all professionals in the field of electricity.

Is the NR-10 course valid?

The NR-10 course has a validity, but that does not mean that your certificate must be discarded. When we refer to the expiration date, it is the time to recycle the NR-10 course, which is two years, that is, every two years and I need to recycle the NR-10 course.

The difference between recycling for the full course is the workload, so you need to have completed the full course of NR-10 to perform the recycling. So if you already have a complete NR-10 course and two years have passed, it is not necessary to retake the complete course again, but recycling every two years.

What is the SEP supplementary safety course?

The complementary safety course Electric Power System (SEP) , is for professionals who work with high voltage, exceeding 1000 volts in alternating current or 1500 volts in direct current, between phases or between phase and ground.

The basic NR-10 course is for professionals who work with low voltage, that is, greater than 50 volts in alternating current or 120 volts in direct current and equal to
or less than 1000 volts in alternating current or 1500 volts in direct current, between phases or between phase and ground. To take the complementary SEP course, you must have taken a basic NR-10 course.
