New NR10: Obligation and Criminal Liability
The new NR-10 requires immediate attention because it consolidates stricter electrical risk management requirements, aligning the standard with the Occupational Risk Management model (GRO) established by NR-01 and raising the level of technical evidence expected in audits, inspections, and expert investigations. This is not merely a documentation update: the new NR-10 now demands clear consistency between the risks identified, the control measures implemented, the training provided, and the operational evidence that proves compliance in practice.
This understanding is not limited to NR-10, as it represents a broader regulatory direction that impacts how other Brazilian Regulatory Standards are interpreted and applied (such as NR-33, NR-35, NR-12, NR-20, and others involving critical risks), especially when they require practical training, operational procedures, rescue teams, and objective proof of competence.
From a legal standpoint, this also applies to training delivered in any language: the language of delivery does not remove the obligation to ensure real understanding of the content and practical compatibility with the specific risks involved, otherwise the training may lose its technical validity as a preventive control measure.
Regarding the effective date, the regulatory scenario indicated is that publication will occur in February and that there will be a one-year adaptation period after publication, following the transition approach typically used to allow companies to adjust their management systems, training programs, and operational controls. However, this interval should not be interpreted as “free time” for inactivity: the longer a company delays compliance, the greater the risk of documentary and technical inconsistencies, especially because audits and expert assessments tend to compare the company’s real operational practice against the best available evidence of effective risk control.
Why does the new NR-10 require immediate attention from companies? When does it take effect, and why is staying updated so important?
The new NR-10 demands immediate attention from companies because it raises the standard for electrical risk control, linking the regulation more directly to the Occupational Risk Management framework (GRO) established by NR-01 and making technical evidence requirements far stricter in audits, inspections, and expert investigations. This is not simply a paperwork revision: the updated standard reinforces that organizations must demonstrate a clear and verifiable connection between the hazards identified, the preventive measures implemented (prioritizing engineering solutions, collective protections, and PPE), effectively validated qualification, and the operational procedures applied in the field under real working conditions.
In practice, this increases accountability and drastically reduces tolerance for “generic” training programs that lack traceability, do not match the specific risk profile, and cannot provide evidence of compatible practical competence. The impact is straightforward: if a company cannot technically support what it claims to do, it becomes exposed both to regulatory authorities and to forensic scrutiny in the event of incidents, accidents, or legal disputes.

Which professionals need the New NR-10 training, and why is it mandatory?
The New NR-10 training is required for any professional who performs electrical work or is exposed to electrical risk, whether directly or indirectly. This includes electricians, electrical technicians, maintenance technicians, engineers, supervisors, team leaders, and workers who access electrical rooms, panels, energized equipment, or installations. Under the New NR-10 logic, companies must prove that workers have real competence compatible with the actual risk, not generic certificates. Therefore, professionals involved in planning, executing, supervising, or authorizing electrical activities must be trained to ensure technical compliance and to avoid regulatory and criminal liability exposure.
What are the main changes from the old NR-10 to the new NR-10, and why does this change how companies must prove compliance?
The new NR-10 is not just a wording update: it changes the compliance standard itself. In practice, it now requires structured electrical risk management supported by evidence, aligned with the Occupational Risk Management framework (GRO) of NR-01, demanding consistency between identified risks, control measures (engineering controls / collective protections / PPE), real qualification, procedures, and operational proof. This reduces the space for generic training and “paper-only” documentation. From now on, what matters is what the company can technically prove during audits, inspections, and expert investigations.
| Topic | Old NR-10 (previous version) | New NR-10 (revision) | Practical impact |
|---|---|---|---|
| Management model | More focused on technical requirements and documentation | Strengthens alignment with Occupational Risk Management (GRO/NR-01) | Requires real management evidence, not only paperwork |
| Electrical risk approach | More generic treatment | Explicit risk management, linked to controls and evidence | Lack of consistency becomes liability |
| Control measures priority | Strong emphasis on PPE | Prioritizes engineering controls + collective protections, PPE as complementary | Risk control must start at the source |
| Incident energy / arc flash | Limited references, uneven application | Stronger trend toward requiring technical criteria, including in design/control | Increased pressure on technical records and specifications |
| PPE selection | General criteria | More objective, risk-based selection criteria | Wrong PPE becomes evidence against the company |
| Training | Often treated as a “standard course” | Reinforces role- and risk-based training, with traceability | Generic certificates lose technical value |
| Operational procedures | Required, but frequently bureaucratic | Requires procedures applicable to real field conditions, integrated with controls | Procedures must work in practice, not only exist on paper |
| Audit/expert evidence | Documents were often enough | Operational evidence gains weight: practice, records, and consistency | Compliance shifts to “show how you do it” |
| Accountability | Focus on obligation to train and document | Higher exposure: inconsistency can generate technical and legal liability | Failures become serious legal risk |
Why can no NR training course be 100% online, especially when it involves critical risks and practical activities?
No NR training course can be 100% online because Brazilian Regulatory Standards are focused on real occupational risk control, which requires verifiable practical competence, not just theoretical knowledge. When an NR involves operational execution, use of equipment, critical procedures, risk analysis, control measures, and emergency response, the company must be able to prove that the training provided is compatible with the actual risk, including practical evaluation where applicable.
Furthermore, during audits, inspections, and expert investigations, compliance is not supported by a generic certificate, but by the consistency between the risks identified in the PGR (NR-01), the training content delivered, the practical application in the field, documented records, and operational procedures. For this reason, 100% online courses tend to fail precisely where it matters most: in real-world practice, objective evidence, and traceability, which are essential to reduce legal liability and ensure effective safety control.

Why is using only an interpreter not enough to deliver an NR course in another language, and why must a qualified technical professional translate and conduct the training?
Because NR training is not a language class it is technical risk-control training with legal responsibility. An interpreter may translate words, but usually cannot guarantee technical accuracy, correct use of regulatory terminology, alignment with operational procedures, and, most importantly, real applied understanding of the workplace risks. In high-risk NRs (NR-10, NR-33, NR-35, NR-12, NR-20, etc.), a misunderstanding can become a failure in risk control, and a failure in risk control can lead to accidents, legal liability, and even criminal exposure.
That is why translation and course delivery must be handled by a qualified technical professional with domain expertise, real field experience, and standardized technical vocabulary. Language is only the “medium”; what companies must prove in audits and expert investigations is valid, traceable training compatible with the real risk, and that requires a specialist not just simultaneous interpretation.
Can a refresher course (“reciclagem”) or only a GWO certification be used as full compliance proof to conclude NR training requirements?
No. A refresher course or GWO certification alone does not replace full NR training requirements, because NR compliance depends on risk-based qualification, traceability, and technical compatibility with the company’s real operational scenario. Refresher training is only valid when it is linked to prior qualifying training, documented competence, and the specific risks identified in the PGR (NR-01). Likewise, GWO is an important international standard, but it does not automatically meet Brazilian NR legal requirements, especially regarding documentation, local regulatory scope, and proof of practical competence. Therefore, relying only on “reciclagem” or GWO is not sufficient to legally and technically conclude NR compliance.
