Occupational safety in large industrial projects is a critical factor that directly impacts worker integrity and project efficiency. In Brazil, Regulatory Standards NR-35, NR-12, and NR-10 establish essential guidelines to ensure safe working environments. This article explores the practical application of these standards, presenting real cases and updated data.
NR-35: Work at Heights
NR-35 sets minimum requirements for safety in work performed at heights, defined as activities conducted above 2 meters from the lower level, where there is a risk of falling. The standard requires proper planning, organization, and execution, including:
- Training and qualification of workers;
- Use of appropriate personal protective equipment (PPE);
- Implementation of collective protection measures.
A relevant case study is that of Sul Brasil Alpinismo, which performed technical cleaning of structures and machines at height in a continuously operating factory. Using rope access, the company executed the cleaning without interrupting operations below, strictly following NR-35 and NR-12. The project was completed in 12 days, with no recorded accidents.

NR-12: Safety in Machinery and Equipment
NR-12 defines technical references and protective measures to ensure safety in the operation of machinery and equipment. Its main points include:
- Identification of risks associated with machines;
- Implementation of physical protections and safety devices;
- Specific training for operators.
Fast Solution, since 2000, has been dedicated to adapting industrial machines to NR-12. In one of its projects, the company developed and installed custom physical protections on industrial band saws, reducing operators' exposure to risk zones. This type of intervention demonstrates the importance of customized solutions to meet NR-12 requirements. Source
NR-10: Safety in Electrical Installations and Services
NR-10 establishes requirements and conditions to ensure the safety of workers interacting with electrical installations. The main aspects of the standard are:
- Development of procedures and work instructions;
- Training and qualification of professionals;
- Use of appropriate protective equipment.
An illustrative case is that of PDCA Engenharia, which conducted inspection reports in more than 60 large industrial sites, identifying non-conformities and establishing adjustment plans according to NR-10. This work resulted in improved operation and maintenance practices of electrical installations, increasing worker safety. Source
Integration of Standards in Large Industrial Projects
The simultaneous application of NR-35, NR-12, and NR-10 in large industrial projects requires an integrated approach. The company Codee developed a multitenant platform for industrial compliance management, automating the management of NR-10 and NR-12 standards. In 12 years of continuous operation, the platform served more than 165 companies, maintaining uptime above 99.9%, demonstrating the effectiveness of technological solutions in safety management.

Conclusion
Effective implementation of NR-35, NR-12, and NR-10 in large industrial projects is essential to ensure worker safety and legal compliance of projects. Real cases demonstrate that, with proper planning, continuous training, and use of appropriate technologies, it is possible to achieve high standards of safety and operational efficiency.
