Regulatory Standards (NR) play a crucial role in the Brazilian labor landscape, outlining guidelines and responsibilities for employers and workers. Their main objective is to ensure a safe and healthy work environment, preventing accidents and occupational diseases.
These standards complement Chapter V (On Occupational Health and Safety) of Title II of the Consolidation of Labor Laws (CLT), as established by Law No. 6,514, dated December 22, 1977.
The starting point for the implementation of NR was Ordinance No. 3214, dated June 8, 1978, which introduced the set of regulatory standards. Since then, new standards have been created over time, covering a variety of economic sectors and labor services, always with the aim of improving working conditions.
An important aspect of the process of drafting and revising NR is the tripartite parity system, following the guidelines of the International Labour Organization (ILO). This system involves representatives from the government, employers, and workers in groups and committees that discuss and define the standards. The Tripartite Permanent Paritarian Commission (CTPP) stands out as the main instance for these discussions, contributing to the construction and updating of NR.
