The development of NR-34 was driven by the revival of the shipbuilding sector in 2003 due to offshore oil exploration needs. NR-18 was insufficient for shipbuilding and repair, leading to the creation of the Tripartite Commission on Working Conditions in the Naval Industry (CT Naval) in January 2008. During its first meeting, it was decided to develop health and safety procedures for shipbuilding and repair.
The CT Naval held meetings at shipyards nationwide, creating safety procedures for activities like hot work, scaffolding, working at heights, and load handling. On July 10, 2009, CT Naval proposed creating a new standard to the Permanent Tripartite Commission (CTPP). The draft was put to public consultation and approved by the CTPP on September 22-23, 2010. NR-34 was published on January 20, 2011, titled “Work Conditions and Environment in the Shipbuilding and Repair Industry.”
NR-34 covers safety measures for activities such as hot work, work at heights, exposure to ionizing radiation, blasting and hydroblasting, painting, load handling, scaffolding, temporary electrical installations, leak testing, structural stabilization, work with floating structures, and emergency response plans. Classified as a Sectoral Standard in 2018, NR-34 has undergone eight amendments, all approved by the CTPP.
