Electrical safety: NR-10
The Brazilian standard on the safety of people working with electricity. It has been rewritten and takes effect on 1 June 2027.
Why NR-10 matters
NR-10 sets out the control measures and preventive systems for the safety of everyone who interacts with electrical installations and services. It requires organised documentation, inspections of the installations, procedures, and training and authorisation of workers.
With the new text, companies have less than a year to adapt. Those who start now reach the deadline calmly; those who wait reach it with the labour inspector.
NR-10 (Safety in electrical installations and services) is backed by arts. 179–181 of the CLT. It was rewritten by MTE Ordinance No. 737/2026, published on 1 June 2026, which takes effect on 1 June 2027. Until then, the previous text applies.
