Norma Regulamentadora No. 14 (NR-14) establishes minimum safety requirements for the construction, installation, operation, and maintenance of furnaces, in accordance with Brazilian labor laws. Originally issued in 1978, it underwent a single revision in 1983, along with other regulations. Unlike later norms, the tripartite model wasn’t used for its revision, as it wasn’t adopted in Brazil until 1996. NR-14 was not discussed in the Tripartite Permanent Paritarian Commission (CTPP) and did not have a Tripartite National Thematic Commission (CNTT) for oversight.
